Answer:

Character Monocotyledon Dicotyledon

Definition The plants in which the seed have only one cotyledon are known as monocots. Such plants are MONOCOTYLEDONS. The plants in which the seed have two cotyledons are known as dicots. Such plants are dicotyledons.

Answer:

The main DIFFERENCE between Attitude and EGO is that while attitude is a person's opinion about other things or persons, the ego is a person's THOUGHT about himself. Attitude MAKES a person think and act differently from others in a good manner while the ego makes a person lonely or ALOOF from others.

Answer:

Clouds form when the invisible water VAPOUR in the air condenses into VISIBLE water droplets or ice crystals. There is water around us all the time in the form of tiny GAS particles, also known as water vapour. There are also tiny particles floating around in the air – such as SALT and dust – these are CALLED aerosols

Answer:

Primary succession

• It occurs in an area which is barren or lifeless.
• Soil is absent at the beginning of PRIMARY SUCCESSION and the environment is not SUITABLE for sustaining normal life forms.
• There is no humus in the beginning as soil is absent.
• Establishment of biotic community is very slow rather than in SECONDARY succession it is very faster e.g., succession on newly cooled lava.

Answer:

im Of The Experiment

To study and demonstrate the amount of water that is imbibed by raisins.

Theory

What is imbibition?

It is the phenomena wherein water adsorption takes place by substances without solution formation. Example: When seeds are immersed in water, they swell due to imbibition. This SWELLING up causes a temporary increase in the volume of the cell and does not require ENERGY as MATERIALS are transported passively.

Raisins increase in size due to imbibition of water. The quantity of water imbibed can be obtained by considering the difference in the mass between the dry raisins and the swollen raisins.

How is water transported to different parts of the plants?

It is transported through imbibition, diffusion, and osmosis.

What are imbibants and adsorbents?

They are the substances that imbibe water. Example of imbibants – Starch. The adsorbent is the liquid that is imbibed.

Why does Imbibition occur?

It primarily occurs due to the presence of lyophilic and hydrophilic colloids. Through the sub-microscopic capillaries that are located on the body’s surface water is imbibed.

The imbibition of water continues until a dynamic equilibrium is established which causes an increase in the imbibant’s volume resulting in imbibitional PRESSURE which is of enormous magnitude.

How is imbibition affected?

Some factors that can affect the imbibition rate are:

Temperature – Imbibition rate is directly affected by the temperature

Imbibant’s nature – Starch has lesser capacity while proteins have a great IMBIBING capacity.

Solute’s concentration – It is indirectly proportional to the rate of imbibition. Increase in the rate of imbibition is observed when the concentration of solute is less.

Imbibition rate is directly related to the surface area of the imbibant. The greater the surface area the more the rate of imbibition.

Significance Of Imbibition

Germination of seed is inducted by imbibition

The force generated by imbibition is required for the cohesion of water to the elements of xylem

Retention of water by fruits is due to imbibition

Ripening of ovules into seeds is due to imbibition as it causes water movement to the ovules.

Also Refer: Germination of seed

Materials Required

Beaker.

Spatula.

Petri dish.

Blotting paper.

Distilled water.

Electronic balance.

25-30 raisins with their stalks intact.

Procedure Of The Experiment

Take a clean and dried small beaker and add distilled water.

Take around 20 clean, dried and fresh raisins with their stalks.

Weigh the selected 20 raisins on an electronic balance.

Make note of the measurement.

Now add the weight 20 raisins into the beaker with distilled water.

Leave the raisins undisturbed and allow it to soak in water for around 2 to 3 hours.

Take a clean and moisture-free petri dish and cover spread the blotting paper.

Now slowly remove the soaked 20 raisins into a petri dish with the help of a spatula.

Gently pat dry the raisins.

Now again weigh the soaked and dried 20 raisins on an electronic balance.

Make note of the measurement.

Now calculate the difference between the two readings.

Observations

Dry raisins weigh x_________ gm

Swollen raisins weigh y ___________ gm

Calculations

The water absorbed by the raisins weigh = (y – x) gm

The water absorbed by the raisins in percentage = (x-y)/x

Answer:

advantages:

In MULTIPLE fission, the parent cell divides into many DAUGHTER cells. it leads to GREATER chances of SURVIVAL! beneficial for the species.. eg plasmodium.

Many beings/organisms are created at a time. this may be important for the organism if it can't survive for a long time.

disadvantages:

The disadvantage is that SINCE the daughter cells are identical in genes, any changes in the environment that is harmful to one would put the entire population of that group in danger.

Explanation:

Replenishment of soil is essential to regain its CHEMICAL and PHYSICAL properties so that the soil remains fit for CULTIVATION. ... During the fallow period, the soil replenishes its nutrients by the ACTION of microbes and other ANIMALS like worms, insects.

ANSWER:

Adenosine deaminase (ADA) DEFICIENCY is a genetic disorder. In this disease, the GENE coding for the enzyme ADA gets deleted leading to deficiency of ADA abd problems in immune system. Adenosine deaminase (ADA) deficiency in PATIENTS can be treated by gene replacement therapy or enzyme replacement therapy. On this treatment patients are regularly injected with the functional ADA enzyme.

Disadvantages of this procedure :

• It does not completely ERADICATE the disease.
• requirement of repeated doses of the enzyme makes it expensive.

Explanation:

Answer:

If the progenies PRODUCED by a test cross show 50% dominant trait and 50% recessive trait, then the cross in which the genotype of an unknown dominant phenotype can be determined by crossing it with an individual homozygous recessive phenotype for that trait is called a test cross.

This cross determines whether the dominant character is coming from homozygous dominant genotype or heterozygous genotype (e.g., tallness coming from Tt) when Tt is crossed with tt, we OBTAIN Tt (TALL) individuals in the program.

Thus, this test can be USED to determine the hetrozygosity of the plants.

Answer:

Lysosomes

Explanation: Death is a process that consists of different phases that lead to the DECOMPOSITION of the body. One of the first phases, which OCCURS MINUTES after death, is the process known as autolysis, which BEGINS once the cells are deprived of oxygen.

During autolysis, the body's enzymes begin to digest the membranes of the cells, breaking down the whole cells. This process is initiated by organelles known as lysosomes, which are in charge of releasing these enzymes that are involved in the 'digestion of the human tissues.

Answer:

A FUNDAMENTAL principle of nutrition and metabolism is that body weight change is ASSOCIATED with an imbalance between the ENERGY content of food eaten and energy expended by the body to maintain LIFE and to perform physical work. Such an energy balance framework is a potentially powerful tool for investigating the regulation of body weight. However, we need a better understanding of the components of energy balance and their interactions over various time scales to explain the natural history of conditions such as obesity and to estimate the magnitude and potential SUCCESS of therapeutic interventions.

EXPLANATION:

Soil pollution affects food security by REDUCING crop YIELDS and quality. Safe, nutritious and good quality food can only be PRODUCED if our soils are healthy. Without healthy soils, we won't be ABLE to produce enough food to achieve ZeroHunger.
