Erythrocytes (red blood cells)have no nucleus, mitochondria, orother organelles at maturity. Theseorganelles are ejected when the RBCenters the bloodstream, or shortlythereafter. Should this still beconsidered a cell? What will be theeffect of having no nucleus? In thesecells, the lack of mitochondria is anadvantage. Why?
Answer:
Erythrocytes are not considered true cells, because of their lack of a nucleus. The effect of having no nucleus makes their self-reproduction impossible, and the absence of mitochondria is a disadvantage because they have to obtain energy by alternative reactions.
Explanation:
Erythrocytes, or red blood cells, are the structure in charge of transporting gases in the blood. When these cells are mature, they have already lost their nucleus —in order to have space to house the hemoglobin molecule— which prevents mature red blood cells from being able to reproduce.
Additionally, red blood cells do not have mitochondria —the main energy generator in eukaryotic cells— so in order to obtain energy they need to perform lactic fermentation, with a lower enegetic yield, which may be a disadvantage, but sufficient for this structure to perform its function.

1. How much force accelerate a bicycle and rider with mass 60 kg at 1.5 m/s?
Answer:
Force, F = 90 N
Explanation:
Given that,
Mass of the bicycle and rider, m = 60 kg
Acceleration of the bicycle and rider, a = 1.5 m/s²
We need to find the force acting on the bicycle and rider to accelerate. Let it is F. Its force is given by :
F = ma
F = 60 kg × 1.5 m/s²
F = 90 N
So, the force acting on the bicycle and rider is 90 N.

Suppose a scientist found a new fossil that indicated it was a primitive mammal. Relative dating techniques place the age of this fossil at a much earlier time than mammals were thought to exist. What effect will this finding have on understanding of the history of life?
A.
The split between mammals and nonmammals in the tree of life needs to be shifted back.
B.
A new branch needs to be added to the tree of life.
C.
An existing branch on the tree of life needs to be removed.
D. Other fossils need to be retested to be sure that the ages assigned to them are not in error.

The structure labeled "A" open and close the sites where the gases, carbon dioxide and oxygen, are exchanged during photosynthesis. What is the structure labeled A?
The structure A in the question seems missing but the given answer is based on the description given in the question.
Answer:
The gaseous exchange of carbon dioxide(CO2) and oxygen(O2) occurs through small, regulated openings called stomata during photosynthesis.
Therefore the Structure A is Stomata

A scientist is extracting the DNA of a multicellular organism. He finds that 20% of the strands bases are Thymine. Based on Chargaff's rule, what percentage of the
strands bases would be Adenine?
A. 20%
B. 70%
C. 40%
D. 60%
Answer:
A. 20%
Explanation:
A DNA molecule consists of four nucleotides viz: Adenine (A), Thymine (T), Guanine (G), and Cytosine (C). According to Chargaff in his complementary base pairing rule, these nucleotides pair with one another in such a way that A bonds to T, while G bonds to C.
Based on Chargaff's rule, the amount of Adenine in the DNA is equal to the amount of Thymine while the amount of Guanine is equal to that of Cytosine i.e. A=T, G=C.
A + T + G + C = 100%
Hence, in this question, a scientist finds that 20% of the strands bases are Thymine. This means that the amount of Thymine in that DNA will also be 20%. S
Since A=T = 20% in accordance to Chargaff rule.
