I believe that spermatocele is a cyst that develops in the epididymis and is filled with a milky fluid containing sperm. It is an abnormal sac that develops in the epididymis which is a small, coiled tube located on the upper testicle that collects and transports sperm. A spermatocele is usually painless and filled with milky or clear fluid that might contain sperm.
Answer:
If one parent has blood type B and the other parent has blood type O, the percentage of the blood type of the offspring will depend on the genotype of the parent with blood type B.
Explanation:
Knowing the blood type of the offspring of the cross between parents with blood type B and O raises two possible scenarios, depending on whether the genotype of the parent (type B) is B|B or B|O.
Blood type is an inherited trait and is characterized by the presence or absence of surface antigens A and B in the red blood cells, which genetically behave as co-dominant traits.
- <em>Blood type A</em><em> contains antigen A and its genotype can be A|A or A|O.
</em>
- <em>Blood type B </em><em>contains the B antigen, whose genotype can be B|B or B|O.
</em>
- <em>Blood type AB </em><em>contains both antigens and a single A|B genotypic expression.
</em>
- <em>Type O blood lacks surface antigens, and is the recessive trait so its genotype is O|O.</em>
<u>Scenario 1: Parent with genotype B|B.</u>
In this case, knowing that the genotype for type O is always O|O, all offspring would be of blood type B, genotype B|O.
B|B X O|O
Alleles B B
O B|O B|O
O B|O B|O
100% of the offspring would be of blood type B.
<u>Scenario 2: Parent with genotype B|O.</u>
In this case, 50% of the offspring will have blood type O and 50% B.
B|O X O|O
Alleles B O
O B|O O|O
O B|O O|O
In no scenario would offspring of blood type A be possible.
C. It is DNA that provides the information needed to make proteins, which are essential for life. They do this by containing all genetic information
Answer: Option D) Cells in multicellular organisms are specialized to perform certain functions.
Explanation:
Multicellular organisms include humans, reptiles, birds etc. While unicellular organisms include amoeba, paramecium etc
From the examples given, the cells of multicellular organisms are specialized in function in that:
- cells that perform similar functions are put together as tissues, organs or system e.g digestive system consists of the similar cells that help to break down food into pieces
On the other hand, unicellular organisms possess just one cell that do all the functions.
Thus, the difference between both is that cells in multicellular organisms are specialized to perform certain functions.
