What function does mRNA serve in the Covid vaccine?Your cells learn how to produce duplicates of the spike protein from the mRNA in the vaccination. If you later come into contact with the actual virus, your body will be able to detect it and fight it off. The instructions are sent by the mRNA, which is then degraded and eliminated by your cells.
mRNA vaccines: are they better?Many scientists believe that the large amounts of virus-blocking antibodies, known as neutralizing antibodies (nAbs), that the mRNA vaccines produce explain why they are so effective at preventing infection.

The image shown is of a cell cycle. Cycle phases are prophase, metaphase, anaphase, and telophase.
What is a cell cycle?
A cell cycle is the sequence of events that take place in a cell leading to its division and duplication (replication). It consists of two main parts: interphase and the mitotic phase. During interphase, the cell grows and DNA is replicated in preparation for cell division. During the mitotic phase, the cell divides into two daughter cells.
A cell spends the majority of its time in interphase, which is when it develops, duplicates its chromosomes, and prepares to divide.
The cell then exits interphase, enters mitosis, and divides to completion. Each of the resulting cells, known as daughter cells, enters its own interphase to begin a new cell cycle.
The cell cycle is the process by which cells multiply and divide into two new cells. The cell cycle phases are G1, S, G2, and M. At the G1 stage, cells are getting ready to divide.
Therefore, The given image is of cell cycle. The phases of cycle are prophase, metaphase, anaphase and telophase.

Why are gametes the only haploid cells in your body?
Gametes are the only haploid cells in the human body because they are the cells involved in sexual reproduction, which requires the combination of one set of chromosomes from each parent to form a new individual. The rest of the cells in the human body are diploid and do not participate in sexual reproduction.
Gametes, which are also known as sex cells, are the only haploid cells in the human body because they are the cells that are involved in sexual reproduction. Haploid cells have a single set of chromosomes, while diploid cells, which make up the majority of cells in the human body, have two sets of chromosomes.
During sexual reproduction, gametes from each parent combine to form a new individual. The gametes from each parent contribute one set of chromosomes to the offspring, so that the resulting diploid cells in the offspring have two sets of chromosomes, one set from each parent.

Answer:
Human gametes are haploid (n) as they are formed by meiosis during the process of gametogenesis.
Explanation:
Haploid can be described as a cell that contains a single set of chromosomes. The term haploid can also refer to the number of chromosomes in egg or sperm cells.
Haploid gametes lead to the fusion of male and female gametes, by which a diploid zygote is formed and the number of chromosomes remains the same in the progeny.

living organisms?
O a. Homologous structures
O b. Vestigial structures
O c.
Index fossils
O d. Analogous structures
Answer:
d. Analogous structures is not a good method in examining fossils anatomical features of living organisms.
Explanation:
Analogous structures are physical characteristics that are similar in different organisms due to convergent evolution, rather than being inherited from a common ancestor. While analogous structures can provide valuable information about the environment and adaptations of living organisms, they are not helpful in examining the fossils of ancient organisms because they do not reflect the evolutionary relationships between different species. Homologous structures, vestigial structures, and index fossils are all useful methods in examining fossil anatomy, as they can provide insights into the evolutionary relationships and characteristics of ancient organisms.

What would happen if a new predator were introduced to prey with which it has not coevolved?
Answer:
If a new predator were introduced to prey with which it has not coevolved, it could have a devastating effect on the prey species. The prey species may not have adapted behaviors or physical characteristics to protect themselves from the new predator, making them easy targets for predation. This could lead to a decrease in the prey population and an increase in the predator population, ultimately resulting in the destruction of the prey species. Additionally, the introduction of a new predator could disrupt the balance of the existing food web, which could have a ripple effect on other species in the ecosystem.
Explanation:
Answer: leading cause of extinction is the introduction of predators into an isolated system like an island or a lake

About 80% of the population can determine their blood type from saliva, tears, sweat or milk. These are known as secretors, and they refer to the fact that antigens present in the blood can also be found in bodily fluids like saliva.
What are antigens?Your immune system uses antigens as markers to determine whether or not something in your body is hazardous. Viruses, bacteria, cancers, and healthy bodily cells all include antigens. Antigen testing is carried out to identify viral infections, keep an eye on specific illnesses, screen for them, and ascertain a donor's compatibility with a transplant.
