Gamete;
When the zygote resulting from fertilization of an ovum (female sex cell) continues to grow, producing new cells by mitosis. This will continue until it reaches sexual maturity and then produce new cells by meiosis. These new cells, the germ cells gives rise to sex cells or the gametes.
Zygote;
The result of uniting the sex cells i.e the sperm and the egg is a zygote
Interkinesis;
Or interphase II is a period of rest that cells of some species enter during meiosis between meiosis I and meiosis II. During interkinesis, the single spindle of the first meiotic division disassembles and the the micro tubules reassemble, into two new spindle for the second meiotic division.
Kinetochore;
This is the protein complex assembled on the centromeric region of DNA. It provides the major attachment point for the spindle microtubles during mitotic or meiotic division to pull the chromosomes apart.
Haploid;
This is the quality of a cell or organism having a single set of chromosomes. Organisms that produce asexually are haploid organisms
To test how fertilizer affects tomato plants, a farmer divided a field of young
tomato plants into 10 plots of equal size. The farmer then put fertilizer on half
of the plots and no fertilizer on the other half of the plots. What is the control
group in this experiment?
Answer:
The plots with no fertilizer
Explanation:
In an experiment, the control group is used as a comparison for the experimental group (the group being actively changed and observed).
So, in this experiment, the control group is the plots with no fertilizer.
This acts as a good control group because it provides a normal standard to show the effect of fertilizer on the tomato plants.
So, the control group in this experiment are the plots with no fertilizer.

How do buffers play a role in
homeostasis in living things?
Answer:
Buffers are commonly used in living organisms to help maintain a relatively stable pH.
In biological systems, chemical buffers prevent sharp and sudden changes in pH.
In biology, homeostasis refers to stable conditions required for the survival of organisms.The pH is a scale used to determine how acidic/basic water is. The pH range from 0 to 14 ( a pH equal to 7 is neutral).In human blood normal pH is about 7.35 to 7.45. A sudden change in this value alters and negatively affects the homeostasis of the body.The carbonic acid-bicarbonate is the most important chemical buffer which is used for mantaining acid-base balance (homeostasis) in the blood.The blood pH can change due to respiratory acidosis/alkalosis and metabolic acidosis/alkalosis.In conclusion, chemical buffers prevent sharp and sudden changes in pH.

Human skin color is a good example of polygenic (multiple gene) inheritance. Assume that three "dominant" capital letter genes (A, B and C) control dark pigmentation because more melanin is produced. The "recessive"alleles of these three genes (a, b & c) control light pigmentation because lower amounts of melanin are produced.

Here, from the cross of the purple and white flower, all offspring are purple, which indicates that the purple color is dominant in nature and is present in Option A.
What is Punnett Square?The Punnett square is a tool used to predict the probability of offspring inheriting specific alleles from their parents. If all of the offspring exhibit the same phenotype (such as purple flower color), it is likely that the parents both carried at least one dominant allele for that trait. This would mean that the purple flower color allele is dominant. Here, the parents are both purple and white, so all the offspring are dominant in nature.
Hence, from the cross of the purple and white flower, all offspring are purple, which indicates that the purple color is dominant in nature and is present in Option A.

Explica brevemente en que consiste la teoría de la deriva continental y menciona los contenientes que se crearon a partir de la Pangea
Esta teoría hace referencia al movimiento actual de las placas que sustentan los continentes y que se desplazan a lo largo de millones de años. En toda la historia geológica de la Tierra, los continentes no han estado siempre en la misma posición. Existe una serie de evidencias que veremos posteriormente que ayudaron a Wegener a refutar su teoría. El movimiento se debe a que continuamente está formándose nuevo material procedente del manto. Este material se crea en la corteza oceánica

What are alto-cumulus clouds?Cloudlets, also known as altocumulus clouds, are tiny mid-level layers or patches of clouds that are most often seen as spherical clusters. However, since there are so many different types of altocumulus, they may take on a variety of forms.
Indicators of convection, or increasing heat, in the atmosphere include altocumulus clouds. Warm air rises into the sky, where it cools and condenses nearby water droplets to create the cloud formations that we see from the ground.

In the 1950s the structure of DNA was discovered by using models and x-ray chromatography currently science has used advanced technology to completely map out the genes in a human's body. What would be the best advantage of using this information?
Answer:
Gene therapy to correct defective genes that cause diseases.
Explanation:
Gene therapy refers to the procedure that involves the introduction of nucleic acids (DNA or RNA) into the cells of an organism for the purpose of correcting abnormalities, such as a mutations or in other words to treat a genetic disease.Gene therapy entails bringing a normal and functional gene known as a trans-gene into a cell with altered gene. Another method can bring RNA capable of partially regulating or blocking the expression of an altered gene.The nucleic acids are introduced into the patient's cells by means of a viral vector or injected directly into the cells in the form of naked DNA.pls mark brainliest

Annette has her thyroid gland removed because of a malignant tumor. She takes synthetic thyroid hormone to replace the thyroxine that her thyroid gland would have produced, but she is worried about her blood calcium level since she has lost her source of calcitonin. Does she need to worry about this problem
Answer:
She doesn't need to worry if her parathyroid glands are working.
Explanation:
Although Annette has to worry about the impacts of thyroid gland removal and synthetic thyroid hormone intake, the calcium levels in her body need not be a concern as long as her parathyroid glands are functioning normally.
This is because the parathyroid glands are responsible for regulating calcium levels in the blood, through the production of parathyroid hormones or parathormone.
