Answer:
The figure shows where mitosis occurs in the cell cycle
Explanation:
The strength in the figure is the figure shows where mitosis occurs in the cell cycle and the figure shows stem cell differentiation. Thus, option D is correct.
What is mitosis?
A cell prepares for cell division by replicating its chromosomes, segregating them, and creating two identical nuclei during the mitotic process. The cell's contents are typically evenly divided into two daughter cells with identical genomes after mitosis.
A cell copies each chromosome during mitosis and distributes one copy to each of its two daughter cells. With regard to our example of an instruction manual, it is crucial that each person receive a duplicate of each page.
Each chromosome must be delivered to each of our cells exactly once, without any errors, or the cells may have problems carrying out the genetic instructions.
Therefore, Mitosis occurs after G2 stage in the cell cycle.The strength in the figure is the figure shows where mitosis occurs in the cell cycle and the figure shows stem cell differentiation. Thus, option D is correct.

why is a chromosome smaller than dna
Answer:
A chromosome is not smaller than DNA
Explanation:
In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.
what is the genotype of a ""normal"" male with no hemophilia a?
Answer: XHY
Explanation:
The hemophilia disease will be present in the progeny if they solely carry the Xh allele/alleles and lack the XH gene, the genotype of man is XhY.
What is hemophilia?Haemophilia was once thought of as an example of Mendelian inheritance since the disease phenotype is caused by a mutation in just one gene (F8 or F9).
But research has shown that the illness has strong genetic and phenotypic heterogeneities. The gene for either the factor VIII protein or the factor IX protein has a mutation (different from normal) in hemophilia patients.
The mutation makes the body manufacture insufficient amounts of factor VIII or factor IX.
Therefore, A normal phenotype will result from having one XH allele because this condition is recessive, the genotype of a man is XhY.

what plant cell organelle performs photosynthesis?
A group of students was asked to explain how one organelle in a plant cell directly supports the work or
another organelle to maintain cellular homeostasis. Which of the following students provides the BEST
explanation?
A. Student 1: Lysosomes supply amino acids which ribosomes use to build proteins.
B. Student 2: Vacuoles store genetic information which are used to construct the cell wall.
C. Student 3: Chloroplasts produce simple sugars which mitochondria use to provide energy for the cell.
D. Student 4: Golgi Bodies sort and package lipids which the Endoplasmic Reticulum uses to make proteins.
Answer:
Letter D. Golgi Bodies sort and package lipids which the Endoplasmic Reticulum uses to make proteins.
The student that provides the best explanation is as follows:
Student 3: Chloroplasts produce simple sugars which mitochondria use to provide energy for the cell.What is Cellular Homeostasis?Cellular homeostasis may be defined as the capability of a cell in order to maintain relative stability and function as alterations take place in the internal or external environment.
According to the question, the Lysosomes are the fatal or self destrcutive bags for living cells. Vacuoles store nutrients as well as waste substances of the whole cell in order to prevent cells from being contaminated.
The sorting of important molecules like lipids and proteins is initiated through the endoplasmic reticulum and proceeds to the Golgi bodies through the anterograde pathway.
While the photosynthetic organelle chloroplast captures the radiation energy from the sun and synthesizes simple sugar like glucose which is used by another organelle mitochondria to provide energy for the cell.
Therefore, the correct option for this question is C.

Answer:
F1 Generation
Explanation:
In the study of genetics the offspring of the P generation is referred to as the F1 generation.
In the study of genetics, the offspring of the P generation are referred to as the F1 offspring, or first fillial offspring. Their genetic makeup depends on their parents.
What is inheritance?Inheritance explains how the genes from the parents pass down to the offspring. An example is when both parents are tall because they are purebred, then all the F1 offspring are tall.
The T is represented by tall, and the t is represented by short. TT is purebred tall, and tt is purebred short. When two parents (P generation) are heterozygous for tallness, such as Tt, each will produce gametes such as T and t. From these gametes, three types of individuals are formed, such as purebred tall (TT), heterozygous tall (Tt), and purebred short (tt). These are called F1 offspring.
Hence, in the study of genetics, the offspring of the P generation are referred to as the F1 offspring, or first fillial offspring.

Leading Same Continuous
Explanation:
;)
During DNA replication, the leading strand is assembled in the same direction from the helix unwinding and is synthesized by continuous replication.
What is DNA replication?The biological process of creating two identical copies of DNA from a single original DNA molecule is known as DNA replication. All living things replicate their DNA, which is the most crucial component of biological inheritance.
Because each of the two copies of DNA has one strand that is old and conserved and the other is newly created at the time of replication, this process is known as semiconservative replication.
Thus, during DNA replication, the leading strand is assembled in the same direction from the helix unwinding and is synthesized by continuous replication.
