Consumers pass about 1% of the available energy to the next trophic level.

1 answer:

8 0

The answer to this would be false.

Here is information provided by another Brainly user:

“As little as 10 percent of the energy at any trophic level is transferred to the next level; the rest is lost largely through metabolic processes as heat.”

I hope this information answers your question.

The scientists modified the genes that were turned on/off (expressed) in mice. What happened to the offspring of these mice?

daser333 [38]

The resulting mice will be induced with the changed gene either on or off. The offspring will have altered genes if both the alleles have the trait. This is a heritable change.

Explanation:

Making gene on or off is a process of gene regulation when one of the gene is methylated or histone modification to prevent access to transcription factors hence no expression of the protein. This process is called epigenetics.

The resulting progeny in mice will receive the allele of on or off the gene. Such genes with altered allele are also called as

The altered genes will be expressed in the resulting progeny of mice.

The epigenetic genes can be reverted with environmental effects in the offspring paramutable alleles. They are heritable.

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 the probability that, given enough time, all tigers in the population will have horizontal stripes is 30% = 0.3.

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

Available data:

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%.
