Some organelles, such as the endoplasmic reticulum and Golgi bodies, have a large and folded structure. What is an advantage of these organelles having a folded structure?
Answers
Answer:
Explanation:
In endoplasmic reticulum, many folds leads to an increase in surface area for ribosomes to attach which allows for protein synthesis to occur at an efficient rate.
mitochondria has two membrane,
It has an inner membrane which is folded inside the other. The fold create cristae, which is the site for a portion of cellular respiration.
The folds also enables a large surface area that makes chemical process to occur in an efficient way.

Answers
Answer:
uncontrolled growth
Explanation:
Cancer is unchecked cell growth. Mutations in genes can cause cancer by accelerating cell division rates or inhibiting normal controls on the system, such as cell cycle arrest or programmed cell death. As a mass of cancerous cells grows, it can develop into a tumor.

Why does a vestigial pelvis show that the ancestors of the modern whale once had legs?
Answers
The vestigial pelvis present on the whale shows that ancestors of modern Whales once had legs, and they had walked on land for more than 40 million years ago.
What are vestigial organs?Vestigial organs that were present in the past and the past generations, but are now unusual in the current generation, but still, are present in the body.
Some examples of vestigial organs are the nictating membrane of the eye, the pelvic bone of a whale, and the appendix organ.
For a very long time, scientists assumed that the diminutive size of the bones was due to their being vestigial, a shrunken evolutionary relic. Derived from an ancestor who formerly traversed the land.
Thus, however, scientists now know that these tiny bones actually serve a significant role in whale reproduction.

EH which lesson is it from??
Explanation:
Answer:
For the first box (top left one), it is AA
For the second box (top right one), it is Aa
For the third one (bottom left one), it is aA
For the fourth one (bottom right one), it is aa
This one above ^^^ is the top line of the punnet square (the small line)
A = free-hanging earlobes
a = attached earlobes
For the first box (top left one), it is free-hanging earlobes (both "A"s are dominants, and the dominant is greater than the recessive one).
For the second box (top right one), it is free-hanging earlobes (there is at least one dominant A so it will be greater than the other "a" although there is a chance for it to be an attached earlobe, but in this case, it isn't)
For the third one (bottom left one), it is free-hanging earlobes (again, there is at least one dominant A so it will be greater than the other "a" even though, there is a chance for it to be an attached earlobe, but in this case, it isn't)
For the fourth one (bottom right one), it is attached earlobes (both "a"s are recessive, there is not one dominant "a" which means that it will be an attached earlobe".
This one above is ^^^ is for the second line in the punnet square (the longest line) P.S you dont have to write the explanation you can just write if it's an attached earlobe or a free-hanging one
The ratio will be 75% to 25%. The 75% will be the offsprings inheriting the free-hanging earlobes, and the 25% will be the offsprings inheriting the attached earlobe. It is most likely that the offspring will inherit the trait for free-hanging earlobe since it is the dominant allele there is.

The HIV infection is different from a cold virus because HIV attacks lymphocytes directly (Option C).
What is the HIV infection virus?The HIV infection virus is a retrovirus that causes human immunodeficiency virus infection (AIDS). This virus is able to attack cells of the immune system such as lymphocytes directly and cause damage in the immune responses or immunosuppression,
Therefore, with this data, we can see that the HIV infection virus is able to cause the death of cells of the immune system, thereby hampering the immune response and triggering the process of immunosuppression.

Which of the following is True?
A. Fertilization requires two haploid cells.
B. Homologous chromosomes have the same alleles, but they may have different genes.
C. Diploid cells have two identical copies of each chromosome.
D. Both A and B are true.
Answers
Answer:
A - “Fertilization requires two Haploid cells.
Explanation:
“Fertilization requires a haploid sperm and a haploid egg”.
Both A and B are true about fertilization and homologous chromosome. Therefore, option (D) is correct.
What is fertilization?Fertilization is the process of combining the genetic material of two sexually reproducing organisms to produce a new individual.
In animals, fertilization typically involves the fusion of a sperm cell and an egg cell, also known as gametes. The sperm cell is produced by the male and carries a single copy of each chromosome, while the egg cell is produced by the female and also carries a single copy of each chromosome. When the sperm fertilizes the egg, the resulting zygote has a complete set of chromosomes, with one copy inherited from each parent. The zygote then goes through a series of cell divisions to develop into a full-fledged organism.
In plants, fertilization typically involves the fusion of two gametes produced by the male and female reproductive organs of the plant. The resulting zygote develops into an embryo, which grows into a new plant.

Once a plant obtains carbon dioxide from the atmosphere it produces __________ as an energy source through photosynthesis.
A. Water
B. Glucose
C. Carbon
D. Carbon Dioxide
Answers
answer:
B
Explanation:
6CO2+6H2O+energy from sun=C6H1206+6O2
C6H12O6 is a form of glucose
Once a plant obtains carbon dioxide from the atmosphere it produces glucose as an energy source through photosynthesis. Thus, option B is correct.
What is photosynthesis?Photosynthesis is the process by which green plants prepare there own food in the presence of sunlight and during this process heat energy converted into chemical energy.
Leaf is known as site for photosynthesis it means the process of photosynthesis that occurs in leaf. The main function of leaf is to produce food material for plants which will help plants to get nourished.
Plants absorb nitrates in water through their roots without nitrates, the amount of chlorophyll in leaves reduces.
Nitrate is a common inorganic ion found in plants that is required for proper growth and development. Many growers include the addition of nitrates in their nutrient regiment to stimulate plant growth. Plants acquire nitrate through root intake from the soil and water around them.
Therefore,Once a plant obtains carbon dioxide from the atmosphere it produces glucose as an energy source through photosynthesis. Thus, option B is correct.

Production of gametes from diploid cells exists the correct answer. This is not one of the functions of mitosis.
What is meant by mitosis?Multicellular creatures depend on mitosis to produce new cells for growth and to replace damaged or worn-out cells, such as skin cells. Asexual reproduction in many single-celled organisms is mostly accomplished through the process of mitosis.
When a cell splits into two, mitosis, a type of cell division, ensures that each new daughter cell has the same genomic makeup.
During mitosis, two cells known as daughter cells are produced. The number of chromosomes must remain constant, and any newly formed daughter cells must have genetic material that is similar to that of the parent cell.
After cell division, it aids in keeping the same number of chromosomes in the daughter cells. It is in charge of the expansion and maturation of multicellular organisms. It aids in the healing of broken tissues. It aids in maintaining the right size of the cell.
Therefore, the correct answer is option a) divides the chromosomal number in half.
