Endoplasmic reticulum serves as transpiration area. The correct option is B.

<h3>What is endoplasmic reticulum?</h3>

The endoplasmic reticulum (ER) is a large, dynamic structure in the cell that performs numerous functions such as calcium storage, protein synthesis, and lipid metabolism.

The ER's various functions are carried out by distinct domains, which include tubules, sheets, and the nuclear envelope.

The endoplasmic reticulum can be smooth or rough, and its function is generally to produce proteins that allow the rest of the cell to function.

Ribosomes, which are small, round organelles that make proteins, are found in the rough endoplasmic reticulum.

Thus, the correct option is B.

From which of the following does the right atrium receive blood?
olga2289 [7]

The right atrium receives blood returning from others parts of the body through the superior vena cava and the inferior vena cava.  

Explanation:

The pathway of circulation begins in the right atrium which receives the carbon dioxide-rich deoxygenated blood returning through the systemic circulation.  

The deoxygenated blood from regions superior to the heart, i.e., the head, neck, shoulder areas are collected through the superior vena cava and that from the parts inferior or lower to the heart like visceral organs, extremities, trunk, hip etc are brought through the inferior vena cava.

Both these venous systems (superior and inferior) fill the right atrium.

The right atrium then pumps the deoxygenated blood to the right ventricle via the tricuspid valve.

The right atrium is filled with blood during diastole.

In beetles, the gene for color and the gene for pattern are located on the same chromosome and exhibit recombination. The lined
Pie

Explanation:

The genes that determine color and pattern are linked.

  • Solid pattern allele (L) is dominant over lined pattern (l)
  • Blue color allele (B) is dominant over aqua color (b)

<h3><u>Initial cross</u></h3>

Homozygous lined aqua beetle has the genotype <em>lb/lb</em>

It can produce only 1 type of gamete: <em>lb</em>

X

Homozygous solid blue beetle has the genotype<em> </em><em>LB/LB</em>

It can produce only 1 type of gamete:<em> </em><em>LB</em>

The F1 is formed by the union of the parents' gametes, so it will have the genotype  <em>lb/LB</em>

<h3><u>F1 test cross</u></h3>

Test crosses involve a homozygous recessive individual.

<u>The homozygous recessive individual</u><u><em> lb/lb</em></u><u> can only produce 1 type of gamete:</u>

  • <em>lb</em>

<u>The F1 individual </u><em><u>lb/LB</u></em><u>  can produce 4 types of gametes:</u>

  • lb - parental
  • LB - parental
  • lB - recombinant
  • Lb - recombinant
