The population after 40 years will be 400,000 animals, and the population after 65 years will be approximately 336,000 animals.

To determine the population after a certain time period, we can use the formula for exponential decay;

N(t) = N0 × \((1/2)^{(t/T)}\)

Where;

N(t) is the population at time t

N0 is the initial population

t is the time elapsed

T is the half-life of the population

Given;

N0 = 1.6 million

T = 20 years

Let's calculate the population after 40 years;

N(40) = 1.6 million × \(1/2^{(65/20)}\)

= 1.6 million × (1/2)²

= 1.6 million × (1/4)

= 400,000

Therefore, the population after 40 years will be 400,000 animals.

Now, let's calculate the population after 65 years;

N(65) = 1.6 million × \((1/2)^{(65/20)}\)

= 1.6 million × \((1/2)^{(13/4)}\)

≈ 1.6 million × 0.210

≈ 336,000

Therefore, the population after 65 years will be approximately 336,000 animals.

The extracellular matrix has no influence on the cells it envelops. The polysaccharides in the extracellular matrix influence the cell's growth size.

Tight junctions close gaps between cell membranes, enhancing an internal cavity's selectivity by forming a strong barrier against fluids and ions. Tight connections constitute the blood-brain barrier. Gap junctions, on the other hand, create microscopic holes to join neighbouring cell cytosols.

As a result, integrins are kinases. Integrins are ligands and extracellular matrix proteins are receptors.

When sympathetic nervous system (SNS) activity increases during exercise, the diameter of arteries increases. Option 7 correct.

During exercise, the sympathetic nervous system is activated, leading to a series of physiological responses to support increased physical activity. One of the effects of SNS activation is vasodilation, which causes an increase in the diameter of arteries. This vasodilation is primarily observed in the arteries that supply the working muscles, allowing for increased blood flow to meet the oxygen and nutrient demands of the muscles during exercise.

The dilation of arteries helps to improve blood flow and oxygen delivery to the muscles, enhancing their performance. It also helps in the removal of metabolic waste products, such as carbon dioxide, from the muscles. The increased diameter of arteries lowers resistance to blood flow, resulting in increased cardiac output and perfusion of the exercising muscles.

It's important to note that SNS activation during exercise can also lead to other physiological responses, such as an increase in heart rate, force of contraction, and the release of epinephrine and norepinephrine, which further support the cardiovascular adjustments necessary for exercise. However, the specific effect on artery diameter is vasodilation.

The Punnett square for the cross between a plant with the genotype tt and another plant with the genotype Tt shows that the offspring will have a 50% chance of having the genotype Tt and a 50% chance of having the genotype tt.

To fill in the Punnett square for the cross between a plant with the genotype tt and another plant with the genotype Tt, we need to consider the alleles of each parent and their possible combinations.

The genotype tt represents a homozygous recessive individual, where both alleles for the trait are lowercase (t). The genotype Tt represents a heterozygous individual, where one allele is uppercase (T) and the other allele is lowercase (t).

Let's set up the Punnett square:

      |  T  |  t  |

---------------------

 t  | Tt | tt |

---------------------

 t  | Tt | tt |

---------------------

In the top row, we place the alleles from the plant with the genotype Tt: T and t. In the first column, we place the alleles from the plant with the genotype tt: t and t.

Now, we can fill in the spaces within the Punnett square by combining the alleles from the top and side:

- The top-left square receives one T allele from the Tt parent and one t allele from the tt parent, resulting in the genotype Tt.

- The top-right square receives one T allele from the Tt parent and one t allele from the tt parent, resulting in the genotype Tt.

- The bottom-left square receives one t allele from the Tt parent and one t allele from the tt parent, resulting in the genotype tt.

- The bottom-right square receives one t allele from the Tt parent and one t allele from the tt parent, resulting in the genotype tt.

Energy is transferred from lower to higher trophic levels of the food chain in any ecosystem.

In other words, energy is transferred when primary consumers feed on producers, when secondary consumers feed on primary consumers, and so on.

However, when energy is transferred through feeding from lower to higher trophic levels, a certain percentage of the energy is lost to the surroundings as heat.

In actual fact, scientists believe that about 90% (and not 30%) of the energy is lost as heat to the surrounding. Only about 10% of the energy is converted to useful energy.

Answer: Biomagnification refers to the process by which the concentration of a contaminant increases as you move to higher trophic levels in a food chain or food web. In other words, as organisms consume other organisms, the contaminants present in the prey accumulate and become more concentrated in the bodies of the predators.

To understand this process, let's consider an example involving a water ecosystem. Suppose a pollutant is released into the water, such as a pesticide or heavy metal. The primary producers, such as algae or aquatic plants, absorb small amounts of the contaminant from the water. As herbivorous organisms consume these primary producers, they ingest the contaminants along with their food.

Since the contaminant is not easily broken down or eliminated from the organisms' bodies, it accumulates over time. As a result, the concentration of the contaminant becomes higher in the herbivores than in the primary producers. Now, when carnivorous organisms consume the herbivores, they not only accumulate the contaminant from their own food but also from all the prey they have consumed. This leads to an even higher concentration of the contaminant in the carnivores.

Therefore, biomagnification describes the phenomenon where the concentration of a contaminant increases significantly as you move up the food chain or trophic levels. The highest concentration of contaminants is often found in top predators, such as large fish, birds of prey, or mammals, which can have adverse effects on their health and reproductive capabilities.

It's important to note that biomagnification primarily occurs for persistent and non-biodegradable contaminants that cannot be easily metabolized or excreted by organisms. These contaminants are often lipophilic (fat-soluble), which allows them to accumulate in fatty tissues and remain in the organism's body for long periods, leading to biomagnification.
