Suppose there are two homologous chromosomes. Each chromosome contains a single mutant allele in different parts of the chromoso
Harlamova29_29 [7]

Answer:

Cross overs can lead to formation of chromosome pairs that have no mutant allele.

Explanation:

Cross overs can lead to formation of chromosome pairs that have no mutant allele.

For example -

Suppose "X" is a mutant  allele and "x" is a mutant free allele.

Now when two homologous chromosomes contains a single mutant allele in different parts of the chromosome are crossed the following offspring are produced

X x

X XX Xx

x Xx xx

"xx" is a mutant free genotype.

Thus, crossing over can create a single mutation-free chromosome

Which describes the missing step?
Nimfa-mama [501]

Answer:

The missing step is oxygen is removed from the water after step 3.

Explanation:

The steps listed by Xavier are:

  1. <em>Water is drawn in trough pores and enters the central cavity. </em>
  2. <em>Food is filtered and digested. </em>
  3. <em>Water leaves trough an opening at the top of the body.</em>

Porifera or sponges are aquatic, immobile invertebrates whose structure is saccular with an upper opening, the osculus.

Sponges absorb water through their pores, where the porocytes are found, and through flagellated cells -the coanocytes- the movement that allows the entrance of water to the spongocele or atrium is produced, in addition to the phagocytosis of organic elements.

Once the water is in the interior chamber of the sponges, the organic particles are phagocyted to be digested, and the oxygen is removed from the water, and passes through diffusion into the cell.  The waste products, as well as carbon dioxide, are released into the water that will be expelled through the osculus.

<u><em>In Xavier's list, the missing step is the removal of oxygen from the water, before it is expelled from the body of the sponge</em></u><em>.</em>

olya-2409 [2.1K]

Answer;

-PET scan

A PET scan uses radioactive markers in the blood to monitor blood flow and metabolic activity via x-ray

Explanation;

-A positron emission tomography (PET) scan is an imaging test that helps reveal how the tissues and organs are functioning. A PET scan uses a radioactive drug (tracer) to show this activity. This scan can sometimes detect disease before it shows up on other imaging tests.

-A PET scan is used to diagnose certain health conditions, to plan treatment, to find out how an existing condition is developing, and to see how effective a treatment is.

-In a PET scan, a machine detects radiation that is emitted by a radiotracer. A radiotracer consists of radioactive material that is tagged to a natural chemical, such as glucose.
