why does the presence of telomeres protect the ends of linear chromosomes?
To prevent the loss of genes as chromosome ends wear down, the tips of eukaryotic chromosomes have specialized DNA “caps” called telomeres. Telomeres need to be protected from a cell's DNA repair systems because they have single-stranded overhangs, which "look like" damaged DNA. ...

Cellular organelles have different structures. Mitochondria, for example, possess highly folded inner membranes in addition to their outer membranes. Vacuoles, on the other hand, are only surrounded by a single-layer membrane; they do not have an inner membrane.
Why do cellular organelles have different structures?
A.
Organelles that are less important to the cell have less sophisticated structures.
B.
All of the organelles in a particular organism are identical, but organelles in different organisms are unique.
C.
The structure of a cellular organelle mimics the appearance of the organism.
D.
The structures of cellular organelles are related to their functions.
Answer:
D
Explanation:
Different oganelles do their own function.
The structures of organelles differ because the structures of organelles are related to their functions.
What are the functions of cell organelles?An organelle is a subcellular structure that has one or more specific functions in a cell, such as an organelle in the body. The most important cell organelles are the nuclei, which store genetic information.
Organelles are small structures in the cytoplasm that perform functions necessary to maintain homeostasis in the cell. They are involved in many processes, such as energy production, the formation of proteins and secretions, the destruction of toxins, and responding to external signals.
Examples of membrane-bound organelles include the nucleus, endoplasmic reticulum, Golgi apparatus, mitochondria, plastids, lysosomes, and vacuoles.

Answer:
destruction of forests
Explanation:Unfortunately, this resulted in the loss of most of the Bengal Tigers habitat. Because of the destruction of forests, where tigers live, the Tiger population decreased dramatically. The new habitat space for tigers was scattered and very small. Many tigers died because they didn't have anywhere they could sustain to live.
The concentration of sodium on the inside of the cell is 20 mM. The outside of the cell has a sodium concentration of 115 mM. Which mechanism of ion uptake would best move sodium from the inside of the cell to the outside? osmosis diffusion passive transport active transport.
Answer:
It's active transport
Explanation:
The mechanism of ion uptake that would best move sodium from the inside of the cell to the outside is active transport.
What do you mean by Ion uptake?Ion uptake may be defined as the process of movement of ions from one side of the membrane to the other.
Active transport helps in the movement of ions against the concentration gradient. It also requires energy. The active transport of small molecules or ions across a cell membrane is generally carried out by transport proteins that are found in the membrane.
Therefore, the mechanism of ion uptake that would best move sodium from the inside of the cell to the outside is active transport.

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.

During DNA replication, the ____ strand is assembled in the ____ direction from helix unwinding and is synthesized by ____ replication.
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.

The figure shows structures in a cell.
The figure shows the steps involved in DNA replication.
The figure shows stem cell differentiation.
The figure shows where mitosis occurs in the cell cycle.
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.

A particular diploid plant species has 48 chromosomes, or two sets. A mutation occurs and gametes with 48 chromosomes are produced. If self-fertilization occurs, the zygote will have _____ set(s) of chromosomes.
Answer:
4 sets
Explanation:
Both gametes will each have 48 chromosomes (2 sets). So if fertilisation were to occur, two of those gametes (both with 2 sets each) the zygote will have 4 sets.
If self-fertilisation occurs, the zygote will have two set(s) of chromosomes.
What is self fertilisation?Self-fertilization, also known as self-pollination, is a type of sexual reproduction in which a hermaphroditic or monoecious organism fertilizes its own gametes. This means that the male and female reproductive organs are present in the same individual, allowing for self-fertilization to occur.
In plants, self-fertilization can occur through a variety of mechanisms, including self-pollination by wind or gravity, or by the transfer of pollen from the anther to the stigma of the same flower. Self-fertilization can also occur in animals that are hermaphroditic, such as some species of snails and slugs.
Self-fertilization can have both advantages and disadvantages for the organism. It can ensure reproduction in isolated or low-density populations, but it can also limit genetic diversity and increase the risk of inbreeding depression.
