Answer:
Antihistamines affect a signal transduction pathway by blocking histamine from binding to the appropriate receptor (First option).
Explanation:
Antihistamines are a group of drugs used in allergic reactions mediated by the immune system. Specifically, antihistamines are competitive inhibitors of histamine binding to its specific receptor, the histamine H1 receptor.
Histamine is an inflammatory mediator, being one of the substances of the humoral immune response. It is secreted by mast cells and is responsible for the production of allergic effects, such as nasal congestion, sneezing, skin rash, and red, watery eyes. Antihistamines block histamine from binding to the appropriate receptor, preventing these effects.
The other options are not correct, because they do not correspond to the effects of antihistamines, that is, it does not bind to histamine, destroy it or render it inactive..

Reduction division during meiosis is one of the reasons diversity occurs in
natures. Which of the following examples represents this process?
A: a human cell with n chromosmes forms a cell wih 2n chromosomes.B: two cells from a horse that contain 64 chromosomes divide to fo 4 cells that also have 64 chromosomes.C:a tomato that has a diploid cells with 24 chromosmes forms gametes with 12 chromosmes. Or D: q cat’s cells with 19 chromosomes, fuse together to form diploid gametes.
Answer:
C
Explanation:
in meiosis the number of chromosomes decreases ( since its reduction division) and c is the only case where this happens
The example that represents the process of meiosis is a tomato that has a diploid cells with 24 chromosomes forms gametes with 12 chromosomes. The correct option is C.
What is meiosis?Meiosis is a type of cell division that occurs in reproducing organisms and results in a reduction in the number of chromosomes in gametes (egg and sperm).
Body (or somatic) cells in humans are diploid, with two sets of chromosomes (one from each parent).
Meiosis is the process by which egg and sperm cells are formed. Mitosis is a necessary process for life.
A cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells during mitosis.
Meiosis is a type of cell division that produces four gamete cells while reducing the number of chromosomes in the parent cell by half. This process is necessary for the production of egg and sperm cells for reproduction.
Here, a tomato that has a diploid cells with 24 chromosomes forms gametes with 12 chromosomes, shows meiotic division.
Thus, the correct option is C.

what evidence supports a conversation law?
Explanation:
The evidence that supports the conservation law is that Carbon dioxide becomes glucose and oxygen during photosynthesis. The law of conservation of mass states that in a chemical reaction, mass is neither created nor destroyed.
Answer:
Chlorophyll converts sunlight to chemical energy during photosynthesis.
Explanation:
Three forms of energy come into play in the functioning of an ecosystem:
* the electromagnetic radiation of short-wavelength (light),
* the electromagnetic radiation of long-wavelength (infrared: heat),
* chemical energy (in the form of organic molecules: sugars, etc.).
The conversion of light energy into chemical energy takes place in plants: it's photosynthesis.

difference between autosomes and gametes
Answer:
An autosome corresponds to a somatic chromosome, which defines structural and functional characteristics in an individual, while the gamete is a cell containing autosomes, useful in sexual reproduction.
Explanation:
The somatic chromosomes are called autosomes, since they contain the genetic information necessary to define the structure and functions of a living being. In humans, there are 23 pairs of chromosomes, of which 22 pairs correspond to autosomes.
The gametes, or sex cells, are in charge of transmitting the genetic information from parents to offspring, and are formed by chromosomes. As gametes are haploid cells, they possess half of the chromosome load, that is, in the human being there are 22 autosomes.
Generally speaking, an autosome is a somatic chromosome, while a gamete is a cell containing autosomes.

DNA replication for ttacg
Answer:
In DNA replication for a TTACG sequence the complementary strand would have the AATGC sequence.
Explanation:
DNA replication is the production of a new strand from an existing strand. The order of the sequence of nitrogenous bases of the new strand is complementary to the original base sequence, taking into account the complementarity of bases, where a purine binds to a pyrimidine:
A=TG≡CAccordingly, if the sequence on the original strand is TTACG, the sequence on the new complementary strand is AATGC.

What is one benefit of using SI units?
Answer:
The greatest advantage of SI is that it has only one unit for each quantity (type of measurement). This means that it is never necessary to convert from one unit to another (within the system) and there are no conversion factors for students to memorize. For example, the one and only SI unit of length is the metre (m).

why cell differentiation is important in the development and growth of a baby from a fertilised egg.
because babies need different types of cells to do different jobs as the fertisiled egg starts to divide each cell specialises to from a part of a body
As the fertilized egg begins to divide, each cell becomes specialized to come from a portion of the body because kids need various types of cells to perform various tasks.
What is the role of cell differentiation in infant?A multicellular creature requires differentiated cells because they can carry out specialized tasks for the body.
Specialization, though, has a price. The trade-off is that differentiated cells frequently lose their capacity to proliferate.
When discrete tissue layers first emerge during a process known as gastrulation in vertebrates, differentiation starts.
Cell differentiation is a crucial process through which a single cell gradually evolves, enabling development that leads to the formation of diverse organs and tissues.
Therefore, for growth and development of baby cell differentiation is important.

Soraya left some soup in the refrigerator. She looked at the soup every day, but she always decided not to eat it. After five days, she started to see mold growing on the surface of the soup. She looked up mold online and found that mold is made of fungal cells. If she ate the soup before she saw the mold, on day 4 when it was still growing, would she have gotten sick?
Answer:
She didn't see the mold growing because mold cells at the start are way to small for the human eye to see. Because of the growth after 5 days, it became visible. She would still get sick because the mold cells are still there, even though mold cells are too small for to see.
