Imagine that you are a marine biologist and you notice that a certain type of crab tends to be considerably smaller in a local b

ay than the same type of crab is in the water outside the bay. What hypothesis might account for this difference? How would you go about testing this hypothesis?

Answer:

Hi, I can try to help.

One hypothesis that could account for the difference in size between the two crabs is the amount of salt in the water. (also called salinity.) Written in "if-then" scientific form, this would be:

<em>"If the salinity levels are lower in a local bay than outside the bay, then the  crabs in the local bay will be considerably smaller than the crabs living outside the bay."</em>

You could go about testing this by measuring the salinity levels where the crabs live, and seeing if there's a major difference in the two bodies of water.

The answer is survival



This is the ceasing of the existence of any particular species. ... A condition in which two populations of the same species, over time, can no longer breed with each other to produce live offspring. Survival. This is the set of skills and abilities necessary for an organism to live. If you’re looking for a one word answer, it’s survival.

A population of 100 tigers has 30 with horizontal stripes. Using pedigrees, you ascertain that horizontal striping is caused by
bixtya [17]

Assuming that this population is in Hardy-Weinberg equilibrium, we can sayt that  <em>the</em><em> probability</em><em> that, given enough time, all tigers in the population will have horizontal stripes is</em><em> 30% = 0.3.</em>

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

<u>Available data:</u>

  • Population size, N = 100 tigers
  • Number of Tigers with horizontal stripes = 30
  • Horizontal stripes is caused by an autosomal recessive mutation.

We need to know the probability that all tigers in the population will have horizontal stripes, which is the recessive phenotype.

We assume that the population is in Hardy-Weinberg equilibrium, so there should be no evolution.

Since the population is in H-W equilibrium, the allelic, genotypic and phenotypic frequencies will remain the same generation after generation.

Now, we will calculate the allelic and genotypic frequencies of horizontal striped individuals in the population.

There are 100 individuals, and only 30 have horizontal stripes.

So, the phenotypic frequency, F(HS) is 30/100 = 0.3 = 30%

Since this is a recessive phenotype, this value equals the genotypic frequency, F(hh) = 30%

Finally, we can get the allelic frequency by taking the square root of this value.

F(hh) = q² = 0.3

f(h) = q = √0.3 = 0.55 = 55%

According to these calcs, the probability for the fixation of the recessive allele is 55%, and the probability that all individuals express the recessive horizontal stripes phenotype is 30%.

Dephosphorylation of glycogen synthase: ____________
jenyasd209 [6]

Answer:

b. Increase in activity of glycogen phosphorylase.

Explanation:

Glycogen synthase exists in two forms which is phosphorylated form which is covalent modification of serine residues by ATP and dephosphoryated form which is obtained using phosphatase on phosphorylated form. Glycogen phophorylase catalyzes hydrolysis of glycogen which shortens glycogen molecules.

The diagram represents a model of DNA replication.
mr_godi [17]

Although there is no attachment, the best answer would be option B.

DNA replication occurs in opposite directions along a strand of DNA.

The leading strand is replicated continuously in the 5' to 3' direction towards the replication fork.

The lagging strand is replicated discontinuously in the 5' to 3' with segments of DNA known as Okazaki fragments.

The number of major histocompatibility (MHC) protein combinations possible in a given population is enormous. However, an indivi
attashe74 [19]

Answer:

The correct answer is "each of the MHC genes has a large number of alleles, but each individual only inherits two for each gene".

Explanation:

In normal conditions, an individual has only two different alleles for a given gene: one inherited from his mother and the other from his father. However, this does not mean that among humans, there are only two different alleles for each gene. The major histocompatibility (MHC) genes are a clear example of this, since there are multiple combinations for each MHC class. For instance, there are 40 very similar alleles only for the HLA-B27 subtype.
