The algae, walleye pollock, and orca populations could have all affected the moon jelly population. What additional evidence do

STALIN [3.7K]

Answer:

There is a balance of resources, shelter, and number of species inside the region which is under consideration. While, the moon jelly's population may increase due to lack of presence of the competition for the resources that are present by means of other consumers of zooplankton that would enhance the growth of the moon jelly's.
Along, with that the decrease in the number of predators which are mainly the big marine animals inside the region that would increase the level or growth of the moon jelly's.

Suppose the human trait for hair type is controlled by a simple dominant and recessive relationship at one locus. Curly hair, C,

Zepler [3.9K]

Answer:

The frequency of the dominant allele, C $= 0.2234$

and the heterozygous genotype, Cc $= 0.1736$

Explanation:

Given -

Curly hair, C, is the dominant allele, and straight hair, c, is the recessive allele

Thus, C is dominant over c

The genotype frequency of curly hair is $52$ in $131$ students

so, remaining $131-52 = 79$ are straight hair students.

Since straight hair is a recessive allele , the genotypic frequency of "cc" is

$\frac{79}{131}\\0.6030$

Frequency of "cc" is represented by $q^{2}$

Thus frequency of allele "q"

$= \sqrt{0.6030} \\= 0.7765$

As per Hardy Weinberg's I equation -

$p+q=1\\p + 0.7765=1\\p = 0.2234$

As per Hardy Weinberg's II equation -

$p^{2} +2pq + q^{2} =1\\0.2234^2+2pq+0.6030=1\\2pq= 0.1736$

Hence,

The frequency of the dominant allele, C $= 0.2234$

and the heterozygous genotype, Cc $= 0.1736$

You are interested in studying a receptor and decide to make a knockout mouse. However, you notice severe developmental defects

Sveta_85 [38]

Answer:

Cell–cell interaction

Explanation:

Based on the scenario being described it can be said that the developmental process that has most likely been affected are known as Cell–cell interaction. These are the direct interactions that exist between cell surfaces that allow them to communicate with one another. Doing so by receiving signals and initiating transduction pathways. Therefore since these are functions that have been disrupted it's safe to say that the Cell-cell interaction has been affected.

Match each component of biodiversity to the example of how it contributes to ecosystem stability.

professor190 [17]

Answer:

Genetic diversity: Some individuals in a population of wild rabbits are resistant to a new disease.

Ecosystem diversity: If the population of wild rabbits decreases, a bobcat can switch its diet to squirrels or woodchucks.

Species diversity: Populations of wild rabbits from a forest and from a neighboring meadow can interbreed, which increases variation.

Biodiversity of an ecosystem is usually explored by three diversities which are responsible for ecosystem stability they are : genetic diversity, ecosystem diversity and species diversity.

Genetic diversity is the variety of genes within a population of species. Each species consists of individuals bearing different genetic composition. Some individuals in a population of wild rabbits are resistant to a new disease because they exhibit genetic diversity within the population as a consequence some individuals exhibit genes which protect them against new disease.

Species diversity is the variety of species within an ecosystem. Populations of wild rabbits from a forest and from a neighboring meadow can interbreed, which increases variation is an example of species diversity. The wild rabbits from a forest and a neighboring meadow are two species living in an ecosystem stating the diversity of species in an ecosystem.

Ecosystem diversity is the variety of ecosystems in a given region.If the population of wild rabbits decreases, a bobcat can switch its diet to squirrels or woodchucks is an example of ecosystem diversity because in an ecosystem there is interaction of organisms as predator prey relationship. This example is also relating with predator prey relationships in an ecosystem.
