Classify each description as true of introns only, exons only, or both.A-present in eukaryotic genomesB-generally absent from ba
maxonik [38]

The right answers are:

A-present in eukaryotic genomes ==> Both exons and introns

B-generally absent from bacterial genomes ==> Introns

C-part of the final mRNA strand ==> Exons

D-code for an amino acid sequence ==> Exons

E-removed from initial mRNA strand prior to translation ==> Introns

F-present in the DNA used as the template for transcription ==> Both exons and introns

In the genes of eukaryotic organisms, the exons are the segments of an RNA precursor that are conserved in the RNA after splicing and that are found in mature RNA in the cytoplasm. The segments of the RNA precursor that are removed during splicing are called in opposition to introns. Exons are mainly found in messenger RNAs (mRNAs) encoding proteins. Some mRNAs may sometimes undergo an alternative splicing process in which one or more exons may be excised or some introns preserved in rare cases.

Describe two examples of steroids. For Each example, describe its physiological function
NARA [144]


Testosterone is an example of a steroid.  Its physiological functions include:

1. Determines the the gender of a developing embryo.

2. Development of reproductive organs and the prostrate gland in males.

3. Responsible for secondary sexual characteristics in males such as deeper pitch, increased muscle bulk, hair on the upper lip.

4. Regulates normal sperm development.

Another steroid is cholesterol. Physiological functions include:

1. Helps maintain the structure  of cells and vessels improving overall health and function in the body.

2. Precursor to important sex hormones such as testosterone and estrogen.

3. Used as an insulator around nerves and is absolutely essential for brain function.

4. Precursor to Vitamin D,  which supports a healthy immune and nervous system

Adaptations of cones and rodes
iris [78.8K]

Answer:

Both cones and rods participate in dark adaptation, slowly increasing their sensitivity to light in a dim environment. Cones adapt faster, so the first few minutes of adaptation reflect cone-mediated vision.

PLS HELP!!! What best describes the relationship between
rusak2 [61]

Answer:

Interspecific competition

Explanation:

Interspecific competition occurs when two different species occupy the same environment as they coexist and depend on the same limited resources for survival. As a result of these limited resources, there's competition between the different species with each species having their different levels of fitness. Their level of fitness determines how well they will complete with other species. This will also determine if they will go extinct or thrive in such environment where there's interspecific competition.

The graph given shows the growth of the relative population size of two different species grown together.

It shows that P. aurelia, with time, outcompetes P. coudatum.

This graph clearly suggest that interspecific competition has occurred. Both species are competing for the same limited resources.

P. aurelia has a greater fitness which enables it to outcompete the other species sharing the same environment with it.

Interspecific competition beats describes the relationship between the two species in graph B.
