Independentcy of osteoblast and osteoclastin bone remodelling is called as

Answer»

In the bone-remodeling unit, the rate of osteoclast generation DETERMINES the EXTENSION of the bone-remodeling unit, whereas the life span of osteoclasts determines the depth of resorption. Although both genesis and apoptosis of osteoclasts lead to changes in osteoclast number and bone resorption, ALTERATION of osteoclast life span might represent a more effective mechanism to accomplish rapid changes in bone resorption rate.

Sex steroids have profound effects on osteoclasts. Both estrogens and androgens inhibit osteoclast generation by regulating the production of pro-osteoclastogenic cytokines (such as IL-6 and IL-1) by cells of the stromal/osteoblastic lineage. Estrogens also induce apoptosis of mature osteoclasts. This, together with an inhibitory effect of the hormones on osteoblast generation, leads to attenuation of the rate of bone remodeling.

Mice receiving excess glucocorticoids exhibit reduced osteoclast progenitors, but cancellous osteoclast number does not decrease in the early phases of the disease, because glucocorticoids prolong the life span of preexisting osteoclasts. This effect may account for the early transient increase in bone resorption in patients with hyperglucocorticoidism. In contrast to the rapid prosurvival effect of glucocorticoids on mature osteoclasts, glucocorticoids induce a decrease in osteoclast formation caused by a reduction in the pool of osteoblastic cells that support osteoclastogenesis. This effect leads to the TYPICAL low remodeling rate observed in chronic glucocorticoid-induced osteoporosis.

Explain the construction and working of solar light, solar water heating system and solar cooker with the help of neat and labeled diagrams

Answer»

THE CONSTRUCTION OF SOLAR STREET LIGHT. Solar lighting system is the use of natural light to provide illumination. Solar lighting system is the technology of obtaining usable energy from the light of the sun using semiconductor materials and this is energy efficient lighting technology.


Solar water heater uses radiation from the sun to heat up water. Solar water heater does not consume any fuel, so it is used in developing countries like in Africa where fuel is relatively expensive but sunlight is abundant. ... A SIMPLE solar water heater can be constructed using everyday materials.


Construction of a box-type solar COOKER: A box-type solar cooker consists of the following components:

Box (B): This is an insulated METAL or a WOODEN box. It is painted black from inside because black surface absorbs more heat. The box may be provided with four roll-wheels.

Glass COVER (G): A cover made of two sheets of toughened glass held together in an aluminium frame is used as a cover of the box B.

Plane mirror reflector ®: A plane mirror reflector fixed in a frame is fixed to the box B with the help of hinges. The mirror reflector can be positioned at any desired angle to the box. The mirror is positioned so as to allow the reflected sunlight fall on the glass cover of the box.

Cooking containers ©: A set of containers made of aluminium and blackened from outside are kept in the box B. These containers are also painted black because black surface absorbs more heat.

Working: The food is cooked in a shallow vessel of the container. The box has a transparent covering of glass sheet over it. The solar cooker is placed in sunlight and reflector (plane mirror) is adjusted in such a way that a strong beam of sunlight enters the box through the glass sheet. The blackened metal surfaces in the wooden box absorb infra-red radiations from the beam of sunlight and heat produced raises the temperature of blackened metal surface to about 100°C.

The food absorbs heat from the black surface and gets cooked. The thick glass sheet does not allow the heat produced to escape and thus, helps in raising the temperature in the box to a sufficiently high degree to cook the food.

Biologists use ball-and-stick models to study complex molecules by representing atoms with balls and bonds with sticks. DNA is a biological molecule that contains millions of atoms. What is a limitation of using a ball-and-stick model for DNA? Some kinds of atoms that are found in DNA must be left out of the models. DNA has so many atoms that the size and cost of a model could be too great. It is impossible to distinguish different kinds of atoms with models. The chemical bonds between the atoms in DNA must be part of the models.

Answer»

Ball and stick MODEL is considered to be the molecular model of chemical substance which display both 3 dimension position of atoms as WELL as BONDS between them.

The atoms are represented typically by means of spheres connected VIA rods that represent the bonds.

Triple or double bonds are usually indicated by TWO or three curved rods respectively.

Why it is said that vernacular names create confusion

Answer»

It is said that vernacular names CREATE confusion in case of plants. Every region has its own name for a PLANT and thus it SOMETIMES can create confusion.

Using scientific names can eradicate that confusion as it is constant everywhere.

But scientific names are not known to everyone and THEREFORE identification of a plant BECOMES impossible for commoners.

Extinction of tiger can destabilise the entire forest ecosystem and result in a large scale loss of biodiversity'Justify this statement'

Answer»

"When you remove ONE element from a fragile ecosystem, it has far reaching and long lasting effects on biodiversity. This impacts on local communities, habitats and other species which SHARE the tiger's home.

The tiger is at the top of the food chain in all the ecosystems it lives in. As such, it keeps populations of deer, wildbore, sambar and gaur in check. Without the tiger to control them these prey species would expand.

This excessive population would then totally RAVAGE its food source - vegetation. If the vegetation in the JUNGLES was devastated, smaller ANIMALS and insects would not survive there."

What is Homoeostatis and Hormonal Feedback System

Answer»

HOMEOSTASIS
the process by which the body reacts to changes in order to keep conditions inside the body.
FEEDBACK MECHANISM
Hormones alter conditions inside the CELL, usually in response to a stimulus. That means they are activated at specific times. So they MUST be turned on and then turned back off. What turns these hormones and their responses on or off?

Hormone Regulation: Feedback Mechanisms

Hormones control many cell activities, so they are very IMPORTANT for homeostasis. But what controls the hormones themselves? Most hormones are regulated by feedback mechanisms. A feedback mechanism is a loop in which a product feeds back to control its own production. Most hormone feedback mechanisms involve negative feedback loops. Negative feedback keeps the concentration of a hormone within a narrow range.

Negative Feedback

Negative feedback occurs when a product feeds back to decrease its own production. This type of feedback brings things back to normal whenever they start to BECOME too extreme. The thyroid gland is a good EXAMPLE of this type of regulation. 

36.

Parents blood found in the child but the child and parents blood group doesnot similar? Why? Justify your answer.

Answer»

There can totally be the CASE that the BLOOD group of the child does not match to either of his parents

Let me explain it in this way-

For eg. mother has blood group of A and father has B

for mother- either she may have IA Ia or Ia i

For father— he may be Ib Ib or Ib i

So here the child can have his blood group as FOLLOW--

Ia Ia × Ib Ib = AB

Ia Ia ×Ib i =AB or A

Ia i × Ib Ib = AB or B

Ia i × Ib i = AB or A or B or O

So blood group of child can be or cannot be same as that of PARENT.

Why are unsaturated fats better than saturated fats for human ?

Answer»

Is saturated or unsaturated fat better for you?

Last reviewed Fri 27 Apr 2018

By Gillian D’Souza

Reviewed by Natalie Butler, RD, LD

Table of contents

Overall, saturated fat has a LESS healthful effect on the body compared to unsaturated fat. This means unsaturated fat may be a wiser dietary choice, although there are some exceptions.

According to recent FINDINGS, consuming saturated fat may not be bad for health as researchers once thought.

Fat is an essential nutrient that the body NEEDS to function properly. Fats provide ENERGY, absorb CERTAIN vitamins and minerals, help maintain body temperature, and insulate the body's vital organs.

The most recent Dietary Guidelines for Americans (2015–2020) recommend that adults get between 20 to 35 percent of their daily calories from fat.

The effects of deforestation on the following. Wild animals . Environment . Villagers ( rural areas ) . Cities. Earth . The next generations

Answer»

Deforestration means cutting down of trees. Deforestration affects food chain also. As we know that For eg', DEER eats plants,then deer is eaten by canrnivore animal eg Tiger. Carnivore animals are those animals which EAT meat.. Meat eaters...
If we CUT down trees it affects ENVIRONMENT badly.. Plants clean the carbon monoxide coming from factories, chimneys.. We should PLANT more and more trees..
Humans depend on trees also.So we should plant more and more trees.
We get food from plants..

How many divisions are required in a root tip cell to produce 100 cells?

Answer»

Answer:

99

Explanation:

Because

of the Arithmetic division. In first division two CELL are formed but only one cell Undergoes division and the SECOND cell formed get preserved this cycle CONTINUE which means in every step

no. of division = n-1

EG 99 divisions = 100 - 1

* 1 cell( preserved cell ) are Produced during 2nd division because another cell will under go division again

* 2 cell get preserved duing 3rd division

* 3 cell get preserved during 4th division

* 4 cell get preserved during 5th division and so on.

If in a population the predicted genotype is changed then write atleast two possible conditions for this to be happen

Answer»

Key Points

Natural selection can cause microevolution (change in allele frequencies), with fitness-increasing alleles becoming more common in the population.

Fitness is a measure of reproductive success (how many offspring an organism leaves in the next GENERATION, relative to others in the GROUP).

Natural selection can act on traits determined by alternative alleles of a single gene, or on polygenic traits (traits determined by many genes).

Natural selection on traits determined by MULTIPLE genes MAY take the FORM of stabilizing selection, directional selection, or disruptive selection.
