16. Why should the recessive phenotype be used first to determine the q squared value instead of the dominant phenotype to deter

podryga [215]

The recessive phenotype is used first to determine the q squared value because it is only expressed when h0m0zygous.

<h3>What is a recessive phenotype?</h3>

A recessive phenotype is a phenotype which expresses the recessive trait of a gene.

The recessive phenotype is always h0m0zygous for that triat to be expressed.

In the Hardy-Weinberg equilibrium equation, the allele and phenotype frequencies are given as follows:

p^2 + 2pq + q^2 = 1

where;

p^2 is the h0m0zygous dominant phenotype frequency
2pq is the heterozygous phenotype frequency
q^2 is the h0m0zygous recessive phenotype frequency

Therefore, the recessive phenotype is used first to determine the q squared value because it is only expressed when h0m0zygous.

Community ecologists study the factors that determine the abundance of different species. The Abundance of three algae species (

Tema [17]

Answer:

Explanation:

Given that:

The abundance of three algal species in Lake A is now represented by the vectors:

[97, 84, 43] and [100, 80, 50]

Now if we look at Lake A, the change occurring in the vector of algae species can be determined as:

a = [100 -97, 80 - 84. 50 - 43]

a = [3, -4, 7]

Thus, the magnitude of that change is:

$|a| = \sqrt{(3)^2 +(-4)^2+(7)^2}$

$|a| = \sqrt{9+16+49}$

$|a| = \sqrt{74}$

$|a| =8.6 \ mg/mL$

The abundance of three algal species in Lake B is now represented by the vectors:

[25, 59, 22] and [20, 63, 15]

At Lake B, the change occurring in the vector of algae species can be determined as:

b = [20 -23, 63 - 59. 15 - 22]

b = [-3, -4, -7]

Thus, the magnitude of that change is:

$|b| = \sqrt{(-3)^2 +(4)^2+(-7)^2}$

$|b| = \sqrt{9+16+49}$

$|b| = \sqrt{74}$

$|b| =8.6 \ mg/mL$

Hence, for both Lake A and B, the magnitude of change is the same.

Define the five systems of the biosphere be sure to include information to distinguish each system from the others

Virty [35]

Hello!

By the most general biophysiological definition, the biosphere is the global ecologicalsystem integrating all living beings and their relationships, including their interaction with the elements of the lithosphere, geosphere, hydrosphere, and atmosphere.

A population of wolves predates a population of moose on Isle Royale, Michigan, where there are fewer wolves than moose to start

andrew11 [14]

Complete question:

A population of wolves predates a population of moose on Isle Royale, Michigan, where there are fewer wolves than moose to start. The wolves prey on the moose and eat well, allowing them to have abundant offspring. However, as the wolf population rises, the moose population drops, and over time, the wolf population begins to drop also because of the reduced availability of resources. As the wolf population drops, moose are able to better survive and reproduce, causing the moose population to rise. With this abundance of moose, the wolf population is able to rebound until their population exceeds the moose population’s ability to support the number of wolves. Which population dynamic does this series of oscillations represent?

Delayed density dependence
Delayed density independence
Extinction vortex
Carrying capacity

Answer:

Delayed density dependence

Explanation:

The Delayed density dependence occurs when two species are in interaction (prey-predator or parasite-host), and the dynamic of each population follows the dynamic of the other population. The natality and mortality rates of one species follow the rates of the other species.

Delayed density dependence dynamics regulate populations and allow the occurrence of equilibrium or balance in nature.

Predator-prey scenarios

Assuming that the prey lives in the ideal environment with no predators, it shows an exponential growth rate. Prey can grow, develop, and reproduce, increasing its population size. The more available items, the more predator there will be. The predator population increase in size, and its presence affects the prey populations, leading it to decrease. So there are fewer available items to prey on.

The prey population also affects the predator population. After the increase in the predator population size, the number of available prey decreases. The predator lives in an ideal environment but depends on the prey density. The more predators there are, the fewer prey there will be left. The predator population decreases exponentially due to the item's lack. The predation rate depends on density as well as natality and mortality rates.

So, to sum up,

prey population increases in size
predator population increases in size
prey population decreases in size
predator population decreases in size

In this particular example, the wolves population follows the moose population and vice-versa. It is not simultaneous. It happens with a delay.

Moose influences the wolf population because they are their source of food. The more moose, the more wolves there are. The fewer moose, the fewer wolves there are.

This is a density-dependent dynamic because both populations are affected when they reach a high value.

What type of weak bond is formed when the oxygen of one water

Amanda [17]

Answer:

hydrogen bond

Explanation:

The slight positive charges on the hydrogen atoms in a water molecule attract the slight negative charges on the oxygen atoms of other water molecules. This tiny force of attraction is called a hydrogen bond. This bond is very weak.
