Answer:A

Explanation:

Oogenesis results in the production of one functional egg and several polar bodies that are eventually discarded, ensuring the preservation of cytoplasmic resources in the egg for successful fertilization and early embryonic development.

During oogenesis, the process of producing female gametes or eggs, the primary difference compared to males is the uneven division of cytoplasm. In humans, oogenesis begins during fetal development and continues throughout a woman's reproductive life.

In the ovary, oogonia (diploid cells) undergo mitosis to increase their number. One of the resulting cells becomes the primary oocyte, which enters meiosis I but pauses in prophase I until puberty. Each month after puberty, one primary oocyte resumes meiosis I and divides asymmetrically. The division produces a secondary oocyte and a small polar body, which contains a minimal amount of cytoplasm. The secondary oocyte then enters meiosis II but pauses again in metaphase II.

If fertilization occurs, the secondary oocyte completes meiosis II, yielding a mature egg (ovum) and another polar body. The mature egg contains the bulk of the cytoplasm and organelles necessary for embryonic development. The polar bodies, though non-functional, ensure that the cytoplasm is concentrated in the egg and help preserve the genetic material.

Overall, oogenesis results in the production of one functional egg and several polar bodies that are eventually discarded, ensuring the preservation of cytoplasmic resources in the egg for successful fertilization and early embryonic development.

Answer: a

Explanation:

A

The allele frequencies of T and t in this population are the allele frequency of T is 0.80, and the allele frequency of t is 0.20. Therefore, option A is correct.

The relative frequency of an allele at a certain locus in a population, represented as a fraction or percentage, is known as gene frequency or allele frequency. The percentage of chromosomes in the population that carry that allele relative to the whole population or sample size is what is being discussed.

In human statistical genetics, the frequency of an allele in the population is a fundamental quantity. A lot of population and medical genetic studies are based on this amount. Allele frequencies are altered by numerous evolutionary factors. As a result, allele frequencies can be utilized to guess at previous evolutionary occurrences.

The distribution of genetic variation in a population is shown by the relative genotype frequencies. The fraction of all copies of a gene in a population that carry a certain allele is known as relative allele frequency.

Thus, option A is correct.

Answer:

Environmental Factors Interact with Genes

Environmental factors often influence traits independently of genes. But not always. Sometimes the environment changes a gene—either its DNA sequence or its activity level. Either of these effects can change the proteins that are made from a gene, which in turn affects traits.

Explanation:

The virus needs to speak the molecular language of cells. This is how he manages to dominate and enslave them so that they become factories for new viruses, producing the proteins that the infectious agent requires to assemble its descendants. If this conversation is not fine-tuned, even if the virus has the key and enters, it is doomed to failure.

For a virus to be able to enter a cell, it must have the right key. And this key, which are the proteins on the surface of viruses, has to enter the correct lock, the receptors that are on the cell membrane. Cells are actually houses with many different doors and locks. Some viruses have keys that open the lock of any cell and any kind of host, and others do not, so the infection caused by viruses is specific.

With this information, we can conclude that some viruses have keys that open the lock of any cell and any kind of host, and others do not, so the infection caused by viruses is specific.

In this case, they are helping in the stabilization of membrane structure. They are used as receptor molecules.

Answer:

Tapeworms are hermaphroditic; each segment has two sets of male and female reproductive organs, which will fill the segment with fertile eggs as the segment is pushed back from the neck. When the segment is full of eggs, it detaches itself from the adult tapeworm and is passed in the feces (Figure 40).

Answer:

Matter moves from one consumer to another consumer.

Explanation:

Depending on the way organisms get their food, they can be producers or consumers.

Producers are organisms that produce their food. These are usually organisms that possess the pigment called chlorophyll (most plants and some protists and bacteria). Chlorophyll allows them to perform photosynthesis - a process in which they produce the energy necessary for their survival. With the help of sunlight, they turn water, carbon dioxide, and minerals into oxygen and glucose.

Consumers are organisms that can't produce their own food, which is why they eat (consume) other organisms. All organisms (animals, fungi, some plants, etc) that are not producers are consumers.

The common grass shrimp feeds on the phytoplankton, which makes it a consumer. Then, the Atlantic silverside feeds on the shrimp, which means that it is also a consumer. This means that matter moves from one consumer to another.

Answer: The conversation process where nitrogen gas combines with hydrogen to form ammonium ions is known as THE ACTION OF THUNDERSTORMS while when air in the top layer of soil comes into contact with certain bacteria, nitrogen in the air is converted by NITROGEN- FIXING MICROORGANISMS.

Explanation:

About 79% of air is composed of gaseous nitrogen. However, only a few microorganism can make use of this nitrogen. The important sources of nitrogen for plants and most living organisms are the inorganic nitrogenous compounds in soil. In nature, nitrogen is constantly being removed from the soil and returned to it through the NITROGEN CYCLE

Conversation of gaseous Nitrogen into nitrogenous substances such as ammonium and amino-compouds are carried out by:

--> The action of thunderstorms, and

--> NITROGEN- fixing microorganisms.

During thunderstorms, Nitrogen reacts with oxygen to form nitric oxide. The nitric oxide is oxidizes to Nitrogen peroxide which dissolves in rainwater to form nitric and nitrous acid. When these acids enter the soil, they combine with mineral salts to form nitrates. The nitrates then, dissolve in soil water and are absorbed by the plants. These nitrates are converted into plant proteins and become part of the plant body.

Some microorganisms such as the Nitrogen fixing microorganisms are able to absorb nitrogen from the atmosphere and change it into amino-compouds and proteins. Examples of such microorganisms include:

--> the free living bacteria: these include the azotobacter and clostridium

--> the symbiotic bacteria: the rhizobium which is found in the root nodules of leguminous plants

Explanation:

Answer:

Genotype = Aa

Phenotype = Healthy (no cystic fibrosis)

Explanation:

A person with cystic fibrosis would have the genotype, aa, because it's caused by a recessive allele, meaning both alleles would have to be lower-case for the person to have cystic fibrosis. Therefore, if a person has a dominant allele (A) , they'll have the trait (they may pass it down to their children), but they don't have cystic fibrosis themselves.
