Protozoa organisms are a WIDE RANGE most of which are FREE living single celled eukaryotes.

Proto means first

Zoa means animals

So all protozoal SPECIES are assigned to kingdom Protista.

Answer:

The EVOLUTION of the seed habit is related to the retention of the megaspore. Heterospory is thus considered an important STEP in evolution as it is a precursor to the seed habit. Heterospory evolved FIRST in pteridophytes such as SELAGINELLA and Salvinia

Food pyramid is defined as graphic INTENDED to illustrate the principles of good NUTRITION with fruit and vegetables on the BOTTOM representing the BULK of healthy diet and fats and oils at the top.

it is a chart that can be used to see how MANY serving of each food should be eaten each day. it is for having good health. vegetables and fruits gives a lot of vitamins and minerals and few fats but fruits often have more calories and sugar.

It turns to affects the production of the cropand their income. By drying them INSTANTLY, itcould store crops from damages within due course of TIME. When it dry, it starts to evaporate the moisture in the grains so that it is not attacked by fungi.

The THREE PHASES of TAXONOMY were identified by A.P DE Candolle in 1813.

This is similar to a SITUATION where expenses are more than income. Exactly what happens when animal BODY doesn't get enough food for energy synthesis is what will happen in plants.

Photosynthesis is an anabolic pathway. Carbon dioxide from the atmosphere and water from soil get converted to glucose in plants in the presence of sunlight. This glucose acts as food in plants.

Respiration is a catabolic pathway. The glucose breaks down into carbon dioxide and water by using oxygen to release energy. This process is similar to the process of DIGESTION in animals where a complex molecule is broken down into simple molecules.

Now, in a case of prolonged fasting in man the body doesn't get proper food and thus no nutrients are provided to it. To compensate this LOSS the carbohydrates, fats and proteins in the body START breaking down into their simpler forms.

Something similar happens in plants. When the rate of respiration is more than the rate of photosynthesis, the biomolecules present in plants break down to compensate the reduced rate of photosynthesis. This results in loss of dry weight of the plant.

The stopping of menstruation is called menopause. The average age for menopause is 51 years old, but some women will have it a year or two earlier, and some will have it a year or two later. Early menopause is possible, and can happen in a woman’s mid-to-early 40s.

Menopause occurs when the ovaries, which usually make estrogen along with other hormones, stop producing estrogen. Prior to that, women experience something called perimenopause, which are the years leading up to menopause. Some PRESENT with skipped periods or a change in flow—either lighter or heavier. It's normal to expect some changes in your BLEEDING in the latter half of your 40s, but it's still a good idea to talk to your doctor about any changes or abnormalities.

Once a woman begins going through perimenopause, she may start to get symptoms. These symptoms vary from person to person and even from culture to culture. Some women will skip cycles for a couple of months at a time during perimenopause, but if a woman experiences 12 months straight without a cycle during this time, that's menopause. The main symptom of menopause is, of course, no periods for 12 months straight.

Other symptoms of perimenopause include hot flashes, which also vary from person to person. Flashes could last a few seconds or several minutes, and occasionally occur at night, which may cause difficulty sleeping. Some women will also experience hormonal changes that might affect their MOOD, causing depression, anger or impatience.

Menopause also causes changes to the VAGINA. A woman’s vagina may become a little thinner, a little dryer and a little LESS elastic without estrogen. Lack of estrogen may also affect the urethra, which is located right above the vagina, causing it to become dry and inflamed. This may cause some pain with intercourse.

Bone loss also starts to increase with menopause. Once estrogen levels decrease, the bone will start to deteriorate gradually, which can lead to osteopenia, which is weakness of bone, or osteoporosis. Bone loss occurs predominantly in the hips, wrists and spine, which can be very dangerous, as a hip fracture could really change a woman's lifestyle.

FUNCTION OF FILAMENT::::

The MALE reproductive PART of a flower is referred to as the stamen and consists of the filament and the anther. The filament is a stalk-like STRUCTURE that attaches to the base of the flower and SUPPORTS the anther, which is the structure that produces pollen.

Generally, Planktonic Foraminifera or Globigerinacea Superfamily can be comprehensibly described by test trochospiral, planospiral or streptospiral; wall macroperforate, with perforations regularly and geometrically arranged; surface MAY be pitted, with or without spines in adult, but may be smooth in adult excepted for scattered pustules; aperture interiomarginal or areal. As Mr. Afghah nicely mentioned above, keel or carane is the BEST element to distinguish VARIOUS genera, so being or not as well as their arrangement can help us to identify the planktonic foraminifera.

According to the attached file, I believe the age of sediments which you are studying on, is so IMPORTANT to identify correctly. Cretaceous or TERTIARY? Could you please tell me which one?

have talked about the hazards of excess ozone in the troposphere. The troposphere is the layer of the atmosphere that is closest to Earth, running from 0-12 km above the earth's surface.

What we will talk about now is hazards of too little ozone in the stratosphere – the region of the atmosphere that extends from about 12 - 50 km above Earth.

Ozone forms naturally in the stratosphere via dissociation of molecular oxygen (O2) by ultraviolet radiation, and subsequent combination of atomic oxygen (O) with molecular oxygen. Ultraviolet radiation is short wave, high intensity radiation, indicated on the reaction below as hv. (I can't seem to make this hv show as being above the line, indicating that the reaction takes place in the presence of hv, but that's where it should be.)

O2---(hv)-------> O+ O

O + O2 -------->O3

The ultraviolet radiation that dissociates molecular oxygen is referred to as uv-c radiation. It is very short wavelength (<242 nm [recall a nanometer [nm] is one billioneth of a meter]) and very high intensity radiation. This is not the same as uv-b radiation, which is biologically damaging wavelengths, and which we'll SAY more about in a moment.

IT IS IMPORTANT TO HAVE O3 IN THE STRATOSPHERE --

It is earth's primary shield against damaging uv-b radiation. This radiation is also short wave (280 - 320 nm) and high intensity. Ozone absorbs radiation in the 220 - 320 nm band and so keeps most of it from penetrating to earth. Why do we want to be shielded from uv-bradiation?

Well, uv-b radiation is biologically active radiation. It is RESPONSIBLE for causing damage such as:

skin cancers
cataracts
damage to immune systems
injury to plants
injury to marine organisms

Ozone concentrations peak in lower stratosphere (25 - 35 km above Earth), where it serves this protective function. Peak concentrations are generally <10 ppmv. Above this height, the density of gases is so low that O rarely finds O2 to COLLIDE with, so there is not much O3 formation, and below this height, too little high intensity solar radiation (uv-c) penetrates to dissociate much molecular oxygen.

Ozone is also destroyed naturally in the stratosphere, being dissociated by ultraviolet radiation:

O3 ----(hv)----> O + O2

This is the reaction that is responsible for O3's absorbtion of uv radiation that would otherwise reach earth.

The O atom then typically joins with an O2 molecule to reform O3. The O3 goes on to dissociate and reform many times, usually until it collides with a free O atom, forming two relatively stable O2 molecules.


O3 + O --------> 202 (conversion to relatively stable O2)

That is, O3 formation and destruction are normally in a steady state in the stratosphere, such that the rate of its formation is equal to the rate of its removal. (Ozone is also destroyed by odd nitrogen and hydrogen radicals in catalytic cycles which won't GO into, but which have generally been in balance with rates of formation.)

So, what is the concern all about? It is actually a fascinating story.

BIOFERTILIZERS :

Biofertilizers are living microorganisms that improve the heath and quality of different types of soils that help the plants obtain the necessary nutrients. The soil becomes more nutritious and helps the seeds and roots grow to their FULL potential . Biofertilizers activate the microorganisms that are found in the soil, thus restoring the soils' natural fertility and protecting it against soil DISEASES and droughts, which STIMULATES the growth of plants.

BIOPESTICIDES :

biopesticides, or also KNOWN as Biological Pesticides, are natural pest control agents that are obtained from natural substances . They can come from minerals, plants, and bacteria. Using biopesticides has advantages over using conventional pesticides, because biopesticides are less toxic to the environment and natural life .They play an important role in the protection of agricultural foods and protection against unwanted microbial organisms 

The ionization properties of the active-site residues in enzymes are of considerable interest in the STUDY of the catalytic mechanisms of enzymes. Knowledge of these ionization CONSTANTS (pKa values) often allows the researcher to identify the proton donor and the catalytic nucleophile in the reaction MECHANISM of the enzyme. Estimates of PROTEIN residue pKa values can be obtained by applying pKa calculation algorithms to protein X-ray structures. We show that pKa values accurate enough for identifying the proton donor in an enzyme active site can be calculated by considering in detail only the active-site residues and their immediate electrostatic interaction partners, thus allowing for a large decrease in calculation time. More specifically we omit the calculation of site-site interaction energies, and the calculation of desolvation and background interaction energies for a large number of pairs of titratable groups.

The pKa values (ionization constants) of the active-site residues in an enzyme are of importance to the functionality of the catalytic mechanism of the enzyme. Often a catalytic reaction is initiated by the transfer of a proton from a protein residue (the proton donor) to the substrate, and one of the steps in an enzymatic reaction mechanism is normally a nucleophilic attack on a substrate atom or the stabilization of a positively charged intermediate. For catalysis to take place, the proton donor MUST be protonated.

Please NOTE that in case of a post-hysterectomy scenario, a vaginal vault is prepared and the vaginal opening will now end in a blind ending. The semen DEPOSITED during intercourse will get deposited locally and eventually resorped by the tissue or leak out as SECONDARY discharge. Please note that to some extent this also happens in a regular scenario where the uterus is present and in most cases the opening of the uterus which opening into the roof of the vagina (known as Cervix) is tightly closed and allows only some of the semen to ENTER the rest will COME out or get resorped as mentioned above.

In single cells of Nicotiana tabacum L. an auxin-only signal induces elongation and DNA endoreduplication.

A subsequent cytokinin +auxin signal induces cell division first as amitosis leading to DNA DEDUPLICATION,then as mitosis coupled to
normal cycling.During the hormone induced cell elongation nuclei endoreduplicate,there DNA content keeping pace with the INCREASING cell volume.

Ultimately cells can increase their nuclear DNA upto about 16 C.When cell division is induced in these elongated cells,the LARGE nuclei divide by amitosis in a seemingly random way as the two daughter nucleido not always fit in binary series of C-values.

During the subsequent amitotic divisions the nuclear DNA content and the cell volume are further reduced.Finally, cells REGAIN mitosis and start cycling on the 2C/4C level, forming microcalli from which normal plantlets can be regenerated

The chemical compounds, including both fumigants and contact insecticides, which are approved by FAD/WHO for use on food grains to control storage insects, are regularly reviewed. Their safety in use, for PEST control OPERATORS and food-grain USERS, is carefully CONSIDERED before approval is given and that approval may be withdrawn if new circumstances indicate the need for the exclusion of a particular compound. In general, the contact insecticides that are approved for use are compounds of relatively low mammalian toxicity, which are considered to be non-hazardous when applied at prescribed dilution rates for the purposes indicated.

Hearing aids are the INSTRUMENT of choice for the majority of the 26 million Americans with hearing loss, but for those who are deaf or SEVERELY hard of hearing, cochlear implants may be a better option.


While hearing aids amplify sound, a cochlear implant transforms sounds into electrical energy that stimulates your auditory nerve. Your hearing health PROFESSIONAL can recommend the best treatment option for you; however, cochlear implants are traditionally better SUITED for individuals with severe to profound hearing loss – especially for those who have already developed their speech and language skills and haven’t had any LUCK with hearing aids.

Both hearing aids and cochlear implants work best for individuals diagnosed with sensorineural hearing loss, meaning they have damage to the hair cells in the inner ear and/or the nerve pathways from the inner ear to the brain. Sensorineural hearing loss is the most common type of hearing loss in the United States.
