The given question is incomplete as options are not provided, however the options are as follows :
- Golgi bodies
-lysosomes
-microvilli
-multiple nuclei
Answer:
The correct answer is - golgi bodies.
Explanation:
Goblet cells and glandular epithelial cells are cells that produce and secretes a specific type of products that are termed as the mucin to protect the skin and layer mucous membrane they place.
These cells are characterized by a large amount of Golgi body and endoplasmic reticulum as they are involved in the exocytic pathway which means they secrete, glycoproteins, mucin, and other substances. Golgi bodies needed to modify, synthesis, and secretion.
Thus, the correct answer is - golgi bodies.
1) The correct answer is: 128 combinations.
The genetic combinations that are possible through independent assortment can be calculated as 2^n; where n is the number of different chromosomes.
So, using this formula for 7 chromosomes:
2^7 = 128 different combinations.
2) For a zygote produced by two barley parents, the number of possible genetic combinations can be calculated as: 2^n * 2^n
So, for 7 chromosomes: 2^7 * 2^7=16384
Answer: Plants use Carbon Dioxide to produce sugars and energy, so you could expect the high-energy sugars to be depleted as the sugars are used to produce energy, and the sugars cannot be replaced as fast as they are being used.
Answer:
The correct answer is -
Thymine: 20%
Guanine: 30%
Cytosine: 30%
Explanation:
According to Chargaff's rule which states that the purine residues are equal to the pyrimidines residue in DNA sample which means A+G = T+C where A is adenine, G is guanine, C is cytosine and T is thymine. It is also known that A is always equal to T and C is equal to G.
So, A+G+T+C = 100
20+20+G+C
100-40 = G+C
60= G+C
as we know G is equal to C similarly A is equal to T
Thus, G = C= 30%
A= T= 20%
Somatic mutation
This happens in a single
cell of a developing somatic tissue. This cell is the progenitor of a
population of identical mutant cells, all of which have descended from the cell
that mutated. Additionally, they do not occur in cells that give rise to gametes;
therefore, the mutation cannot be passed on to descendants by sexual means. Somatic
mutation are often called acquired mutation because the change in genetic structure
is not inherited from a parent for they do not affect the germline. Thus, to
maintain the mutation, the individual containing the mutation must be clone.
Example: In red delicious apple, the
mutant allele that determine the golden color of an apple arose in a flower’s
ovary wall, which eventually developed into a fleshy part of the apple. The seeds
are not mutant so it will still give rise to red apple tree. Therefore, the golden
delicious apple originally arose from a mutant branch of a red delicious apple
tree.
Germline mutation
If a gene is altered in a germ cell,
the mutation is called germinal mutation. Germline tissue is set aside in the
course of development to form sex cells. Germ cells gives rise to gametes, so if
a mutant sex cell participates in the fertilization, then the mutation will be
passed on to the next generation. Moreover, germinal mutations will not be
expressed in the individual containing the mutation.
<span>Example: A hereditary case of
albinism are often link to germline mutation where individual of this disorder
are more prone to many types of cancers and may have impaired visions.</span>
