Answer:

When the per capita rate of increase ( r) takes the same positive value regardless of the population size, then we get exponential growth. When the per capita rate of increase ( r) decreases as the population increases towards a maximum limit, then we get logistic growth.

Explanation:

Exponential population growth: When resources are unlimited, populations exhibit exponential growth, resulting in a J-shaped curve. When resources are limited, populations exhibit logistic growth. In logistic growth, population expansion decreases as resources become scarce.

Answer:

A. A glycerol head with 3 fatty acid tails

Explanation:

One glycerol attached to 3 fatty acids each

The structure of a Triglyceride is  a glycerol head with 3 fatty acid tails. Hence the correct option is A.

The structure of a triglyceride consists of a glycerol molecule bonded to three fatty acid tails. Glycerol is a three-carbon alcohol with a hydroxyl group attached to each carbon, while fatty acids are long hydrocarbon chains with a carboxyl group at one end. Through a condensation reaction, the hydroxyl group of each glycerol molecule combines with the carboxyl group of a fatty acid, resulting in the formation of an ester bond.

This process is repeated three times, with each fatty acid binding to a different carbon of the glycerol molecule, thus forming a triglyceride. The three fatty acid tails provide energy storage and insulation properties, while the glycerol molecule serves as a backbone for their attachment. Triglycerides are the main storage form of fat in animals and plants.

Hence the correct option is A.

Answer:

Adenine, thymine, cytosine, guanine

Explanation:

some things use uracil instead of guanine but its less common. also to remember which ones pair up, remember Apple in the Tree (Adenine pairs with Thymine), and Car in the Garage (Cytosine pairs with Guanine).

Answer:

reversible reaction

Explanation:

The double arrow denotes a reversible reaction. The reactants become products and the products can become reactants again using the same process.

Explanation:

Conduction, convection and radiation are the modes of heat transfer:

Conduction:

Microscopic level of heat transfer

Also called as thermal diffusion(takes place due to atomic vibrations) and is highly invisible

Primarily occurs in solid-solid systems and stagnant liquids

Convection:

Macroscopic level of heat transfer

Primary occurs in fluids(involves bulk movement of fluids)

2 types of convection are possible — with external source of energy (forced convection) and without external source of energy (free convection)

Radiation:

Transfer occurs through electromagnetic waves

No medium is required unlike conduction and convection. Radiation can occur even in vacuum.

These are different processes of transferring energy from one place to another.

Radiation is the sunlight and (heat). It travels as electromagnetic wave and does not need matter to transfer energy. Hence radiation is the only mode of transferring energy in vaccuum, for example, light of visible and invisible wavelengths reaches from the sun and other stars as electromagnetic radiaton. Human body emits heat wave as radiation.

Convection and conduction refers to energy transfer through the motion of matter. The difference is how the molecules of matter move during the energy transfer.

Convection is that mode of energy transfer when matter also transfer from one place to another during energy transfer. Molecules of liquids and gases can move. So convection occurs in liquids and gases. It is visible when water is boiled on a gas burner.

Molecules of solids are too tightly bound to move. They vibrate about some average positions in space. Conduction is that mode of energy transfer when matter on average is not transferred from one place to another. Propagation of sound through solid wall is an example.

Explanation:

If the concentration of molecules outside the cell is very high relative to the internal cell concentration, the rate of diffusion will also be high. If the internal and external concentrations are similar (low concentration gradient) the rate of diffusion will be low.

Answer:

These findings tell us that possibly this protein has an enzymatic function, that is, it is an enzyme.

Its function can be catalytic as well as analytical.

The substrate binding site should be the largest, while the other regulatory site is the smallest.

Explanation:

This happens since hormones regulate their enzymatic activity through inhibitory sites.

They have another smaller binding site, where when an inhibitory molecule binds, it deforms the morphology of the protein causing it to no longer bind to its substrate at the binding site, therefore they inhibit the chemical reaction that is happening within the enzyme. both catalytic and analytical.

Answer:

4 frogs per year is the answer

In logistic growth, a population's per capita growth rate gets smaller and smaller as population size approaches a maximum imposed by limited resources in the environment, known as the carrying capacity (K).

Formula used:  dN/dT= rN{1-N/K}

Given: k= 840 frogs

            N= 212, r= 1 year

To find: r=?

Solution:

putting value in equation:

                          dN/dT= rN{1-N/K}

                          dN/dT = 1 x 212 {1-212/840}

                   so,    dN/dT= 158.57 ( approx)

Final answer: The correct option is (c)

158 frogs per year

Thus, we can conclude that 158 frogs per year will be the population of frogs.

Vegetative cover and type of soil.

Explanation:

Vegetative cover and type of soil are the factors that affects the amount of runoff that occurs in an area. Vegetative cover reduce the amount of runoff because it makes the soil porous which absorb more amount of water inside the soil while on the other hand, type of soil also affects the runoff such as sandy soil absorb most of the runoff water and sometimes no water is available for runoff.

Answer:

This organism is able to carry out both photosynthesis and cellular respiration. That's why cellular respiration is essential for the survival of the Euglena.

A sequence of chemical processes known as cellular respiration convert glucose into ATP, which can then be used as energy for a variety of bodily functions.

Glycolysis, the citric acid cycle, and oxidative phosphorylation are the three basic processes that take place during cellular respiration. The citric acid cycle happens in the mitochondrial matrix, oxidative phosphorylation happens on the inner mitochondrial membrane, and glycolysis happens in the cytoplasm.

Glucose, ATP, and NAD+ are the initial reactants and ATP and H2O are the end products of cellular respiration. The enzymes phosphofructokinase-1, pyruvate dehydrogenase, and isocitrate dehydrogenase control the rate of cellular respiration.

Disorders that interfere with cellular respiration often impair one or more of the enzymes necessary for it, such as succinyl-CoA synthase or pyruvate kinase.

Therefore, A sequence of chemical processes known as cellular respiration convert glucose into ATP, which can then be used as energy for a variety of bodily functions.
