[tex]\begin{array}{lll}&\underline {\text {Prokaryotic}}& \underline {\text {Eukaryotic}}\\ \\ \text {Nuclear \ membrane \ and \ nucleus} & \text {No \ true \ nucleus \ or} & \text {Has \ a \ true \ nucleus} \\& \text {nuclear \ membrane} & \text {nucleoli \ and \ nuclear \ membrane}\\\\ \text {Membrane \ bound \ cell \ organelle} & \text {None &Present} \\\\ \text {Chromosome \ number \ and \ shape} & \text {One} & \text {Several, more \ than \ one} \end{array}[/tex]

Explanation:

Prokaryotic cells

The plasma membranes surround prokaryotic cells, however, within their cytoplasm, there are no organelles bound to the membrane and there is no nucleus in the prokaryotic cell which differentiates it from the eukaryotic cells

Eukaryotic cells

Eukaryotic cells also have plasma membranes, ribosomes and cytoplasm. Eukaryotic cells also have membrane-bound nucleus, membrane bound organelles, such as chloroplast, mitochondria, endoplasmic reticulum, and Golgi apparatus which together differentiates it from a prokaryotic cell

2. Give one possible reason why the population decreased in 1990 after it had reached its
carrying capacity
1 I

Answers

Answer: The population exceeded its carrying capacity because there were more resources available so many deer reproduced and the population quickly exceeded the carrying capacity.

Explanation:

When the population size exceeds the carrying capacity, the population must decrease. One possible reason is the lack of available resources to support this population size.

What is Carrying Capacity?

A growing population that inhabits a limited space is gradually affected by density, rebounding in the multiplication rate.

The population growth per capita rate decreases as population size increases.

The population reaches a maximum point delimited by available resources, such as food or space. This point is known as the carrying capacity, K.

Carrying capacity refers to the maximum point at which the environment can support a growing population.

K is a constant. It coincides with the population size when natality rate and mortality rate are equal to each other. This is the equilibrium point.

If the population size, N, is inferior to K ⇒ the population still grow.  When N approximates to K ⇒ the population's growth speed decreases. When N=K ⇒ the population reaches equilibrium, When N is superior to K (N>K) ⇒ the population must decrease in size because there are not enough resources to maintain that size.

So when the population size exceeds K, carrying capacity makes the population decrease in size. This is because there are not enough resources for this population to survive.

Probably this population's size exceeded the carrying capacity because there were available resources and animals were not predated by any other species. So this population kept growing until they exceeded the carrying capacity level.

Once they did it, the environment could not support this population size, probably because of the lack of available resources, so the population had to decrease in size. Mortality rate must have increased while natality rate must have decreased.

One possible reason is the lack of available resources to sopport this population size.

D) A population of deer show an increase in antler size over time, which allows them to obtain more mates

Answers

Answer:

D) A population of deer show an increase in antler size over time, which allows them to obtain more mates during mating season

Based on Darwin's ideas, a population of deer show an increase in antler size over time, which allows them to obtain more mates during mating season (Option D).

What is evolution?

According to Darwin, evolution can be defined as descendence with modification, which mainly occurs via natural selection.

Natural selection can be defined as the differential survival and reproduction of the fittest organisms.

In this case, intraspecific competition favors deers more adapted to reproduce in the population.

In conclusion, based on Darwin's ideas, a population of deer show an increase in antler size over time, which allows them to obtain more mates during mating season (Option D).

Black-footed ferrets are native to the Great Plains. They spend most of their
time underground in prairie dog burrows. Which factor would increase an
area's carrying capacity for black-footed ferrets?
A. Increased competition for space
B. Increased number of diseases
C. Increased number of predators
D. Increased availability of food

Answers

Answer:

D. Increased availability of food

Explanation:

Trust

The factor that would increase an area's carrying capacity for black-footed ferrets is the increased availability of food. The correct option is D.

What is carrying capacity?

Carrying capacity is defined as the average population size of a species in a given habitat.

Environmental factors such as adequate food, shelter, water, and mates limit the species population size. If these requirements are not met, the population will decline until the resources recover.

If there is more food available in an area, more black-footed ferrets can survive and reproduce, increasing the species' carrying capacity.

Increased competition for space, more diseases, and more predators would all reduce the carrying capacity of black-footed ferrets by reducing the number of individuals that could survive and reproduce in the area.

Thus, the correct option is D.

You observe every fall that the trees in the forest lose their leaves, but by the following fall, the leaves have disappeared. The most accurate explanation for this observation would be:

Answers

The tree produces a layer called abscission layer, in which nutrients and water are prevented from reaching the tree which stops the leaves from growing

The tree creates a layer known as the abscission layer, which prevents nutrients and water from reaching the tree and inhibits the growth of the leaves. Hormones in the trees cause the process of abscission.

What is abscission layer?

Tiny tubules in the abscission layer are responsible for carrying carbohydrates back into the tree and delivering water to the leaf, flower, or fruit.

The amount of nutrients and water that pass through the tubes is decreased in the autumn because cells in the abscission start to expand and exude a waxy substance.

Abscission of leaves, which takes place in the fall, is the natural loss of an old leaf at the base of the petiole. Many physical and biochemical changes occur during leaf abscission, most of which are controlled by plant hormones.

Therefore, every fall that the trees in the forest lose their leaves.
