Answer:

C. Ootcyte

Explanation:

During the first phase of the ovary cycle, the Ootcyte matures within a follicle.

Answer:

Oocyte

Explanation:

The cortex of ovaries has many follicles and each follicle contains an immature egg in various developmental stages. The immature egg present in the follicle is called oocyte.

The first stage of the ovarian cycle, that is the follicular phase is marked by the beginning of the development of oocytes in several follicles under the influence of follicle stimulating hormone.

However, only one follicle continues developing. By the end of the follicular phase, the mature follicle (the Graafian follicle) bears secondary oocyte in its fluid-filled cavity.

Explanation:

Chromosomes must condense at the beginning of mitosis so they can be separated, with relative ease, into equivalent halves. Chromosomes adopt a compact form to make them suitable for transport.

Condensation also organizes the DNA molecule in such a manner that the chance of the molecule being broken and/or lost is minimized. If the chromosome breaks in one way or another, mutations occur.

Answer:

RNAi allows scientists to turn off one gene specifically to study its effect.

Explanation:

RNAi is widely used technique for silencing the genes by targeting them and then degrading their mRNA. It silence the genes so that their functions could be studied. It is extensively used in research and can be utilized for any gene just by designing RNAi for that specific gene. It can silence a single genes which make it more useful not only in labs but also in therapeutic approaches for treatment of diseases, cancers etc.

Answer:

Pluripotent cells can be almost anything they want to be while totipotent are for ex, like zygotes. They can give rise to placenta and embryo

Answer:

Pluripotent cells, unlike totipotent ones, do not have the capacity to originate a complete living being.

Explanation:

Both pluripotent cells and totipotent cells are examples of stem cells.

Totipotent cells are those that have the capacity to transform into any cell type that can be found in the organism, which can give rise to a complete living being. are found in the embryonic zygote.

Pluripotent cells, on the other hand, do not have this same capacity, because they are not originated from extraembryonic tissues. Examples of these cells are the embryonic stem cells in the basticyst.

Hello Rimind, okay?

First good night. ⇔

A protein is made up of amino acids. Picking up the word amino acid, and breaking it in half, will turn into: amino + acid.

Every time you find:

 C = O

  l

OH

It will be acidic, carboxylic acid.

Every time you find:

NH₂

It will be Amino / Amine.

Being:

C = O

  l           +  NH₂ = Amino Acid.

OH

Note:

One part of the amine grouping is basic (Base) and another (acidic), so we can call it amphoteric (Amino acid which can be shared as much as Base, as much as Acid.)

attention :

There are Central Carbon (Alpha) that has four combinations being ultimately radical and is a determinant of one amino acid for the other. To be an amino acid, there are three regions. Always a bond will have an amine grouping, another bond with acid grouping and the hydrogen represented as (H)

Answer:

The ocean food chain would shrink, as the phytoplankton are the base of the food chain

Explanation:

Atmospheric carbon dioxide levels would increase because phytoplankton are plants that use carbon dioxide in photosynthesis to grow.

Atmospheric oxygen levels would decrease since there would be more carbon dixodie (the carbon dioxide is converted to oxygen and carbohydrates by photosynthesis).

Oceanic pH levels would decrease, that is the ocean would become more acid. This would be due to higher levels of carbon dioxide, which makes carbonic acid when it dissolves.

Answer:

Ratio = 0.43/m

Explanation:

Given parameters:

Surface area of sphere = 588m²

 Volume of sphere = 1372m³

We are solving for the ratio of the surface area to volume. This ratio is very important in so many life processes in both plants and animals.

             Ratio = [tex]\frac{Surface area of sphere}{Volume of sphere}[/tex]

          Ratio = [tex]\frac{588m^{2} }{1372m^{3} }[/tex]

                           Ratio = 0.43/m

Answer:

C. A steep slope

Explanation:

Erosion is the removal of the top layer of the earth or the gathering of lose weathered materials from rock surfaces.

Agents of erosion are wind, water, glacier and gravity.

Along a very steep slope, erosion is highly rife and very prevalent to the extent that everything there is washed away to be deposited at the bottom of the slope or where gradient is more gentle.

On a steep slope, materials moves rapidly and gravity is very great. When these factors are coupled with the prevailing conditions in a place, little to no deposition occurs for soil formation.

The rate of soil erosion would most likely be higher than the rate of soil formation on a steep slope due to the increased movement of soil and reduced water infiltration, leading to limited soil development.

The rate of soil erosion is likely to be higher relative to the rate of soil formation in locations with certain topographical features. An example where this would occur is on a steep slope. Steep slopes tend to have more soil erosion, less water infiltration, and limited soil development due to the force of gravity acting on loosely held soil particles, leading to more rapid and frequent soil movement. The correct answer to the student's question is C. A steep slope. In contrast, a tropical area with moderate rainfall, a temperate forest, and a river delta would typically have higher rates of soil formation and better conditions for soil stability.

Answer:

Antibiotics have helped in a speedy recovery for human illnesses over the past century.

Explanation:

Because anti biotics were not present centuries ago, many would get sick and even die. However, antibiotics work by affecting things that bacterial cells have but human cells don't. This helps to fight off the bacterial cells and fight infections and viruses, leading to a speedy recovery.

Answer:

1. chromosome: tight coils of DNA

2. Eukaryote: a cell that has a membrane-bound nucleus

3. Gene: a specific sequence of DNA nucleotides that carry hereditary traits

4. Prokaryote: a cell whose nucleus is not bound by a membrane

5. Trait: genetic characteristic of an individual

Explanation:

Chromosomes are the thread-like structures that appear during cell division. Each chromosome is made up of DNA tightly coiled with its packing proteins.  

A cell is defined as eukaryote or prokaryote on the basis of the presence of a membrane-bound nucleus. The cells that lack the membrane-bound nucleus and other membrane-bound organelles are called prokaryotic cells. Example: bacteria.

The cells that have a membrane bound nucleus in which DNA is present are called eukaryotic cells. Example: Plant cells.

A stretch of DNA that code for a particular protein and thereby regulate specific genetic trait is called a gene. Genes are present on chromosomes and are carried from one generation to next to maintain the genetic traits.

The features of living beings regulated by the gene are called trait. Example: skin color, eye color, etc.  

Correct matches: 1-Chromosome to tight coils of DNA, 2-Eukaryote to a cell with a membrane-bound nucleus, 3-Gene to sequence carrying hereditary traits, 4-Prokaryote to a cell without a membrane-bound nucleus, and 5-Trait to a genetic characteristic.

The terms and their correct definitions would be matched as follows:

Chromosomes are structures that contain genes, which determine specific traits in an organism. Eukaryotes are organisms whose cells have a membrane-bound nucleus which houses these chromosomes, while prokaryotes lack such a nucleus, often having DNA concentrated in a nucleoid.

Answer:

B. orbit

Explanation:

As an object travels around the sun or other large object, it travels on a fixed path that is  called its orbit.

Answer:

The fact that most eukaryotes reproduce sexually is evidence of its evolutionary success. In many animals, it is actually the only mode of reproduction. The genetic diversity of sexually-produced offspring is thought to give species a better chance of surviving in an unpredictable or changing environment.

Sexual reproduction is crucial for the success of a species because it results in genetically diverse offspring.

Sexual reproduction creates genetically diverse offspring, providing species with a greater ability to adapt to environmental changes and increasing their chance of survival. This diversity provides a better chance for survival in a changing or unpredictable environment, giving rise to a wide range of phenotypes through the combination of genetic material from two individuals. Despite the limitations of requiring both sexes for reproduction, which can impact colonization of new habitats, the benefits of this genetic variation are imperative. It allows for a population to have individuals who might be better adapted to new challenges and also offers a mechanism for selective adaptation.

The mechanisms of meiosis and fertilization enhance genetic variation, a concept often referred to as the Red Queen Hypothesis. This genetic variance acts as a buffer against extinction, as it increases the likelihood that some individuals in a population will possess advantageous traits to adapt to new environmental pressures. Sexual reproduction also allows for the introduction of genetic bottlenecks that can eliminate deleterious alleles from a population and quickens the appearance of beneficial allele combinations.

Answer:

A. some cartilage becomes bone through ossification during childhood development.

Explanation:

Ossification is a process of bone remolding, this starts from fetal stage and continues up to adolescence. The cartilage cells are replaced by the osteoblasts for the formation of bones in the cluster form.

Answer:

option: A

Explanation:

The ossification process allows the formation of new bones in the body. The process begins from the fetal stage and it continues till adult age. The osteoblasts cell replaces the dead cartilagenous cells.

The hematopoietic stem cell synthesizes WBCs not cartilage. The cartilage can easily be transformed to a bone.The cartilage is not primary material for moving shark bones.  As the baby grows the small bones fuses with each other thus forming large bones. So the option A is correct.

Chemotherapy is a process of intense treatment for cancer. It includes one or more anti-cancer drugs. However, most people become sick after they go through with chemotherapy. This can last for days or longer. Hopefully, nobody gets cancer and has to go through this procedure.

Chemotherapy refers to the use of chemicals or drugs to treat disease, often for cancer or to treat infections with antimicrobial drugs. It works by killing or inhibiting growth of target cells and is frequently used when other treatments are limited or not possible.

Chemotherapy is a broad term that refers to the use of chemicals or drugs to treat disease. It is frequently associated with cancer treatments but can also refer to antimicrobial drugs that target infectious microorganisms. These drugs generally work by either killing target cells or inhibiting their growth, such as in the case of cancerous structures or infectious microbes.

The use of chemotherapy in cancer treatments involves drugs that interfere with the rapid cell division of cancerous cells. Such treatments are typically used when surgical removal of a tumor is not possible or when other traditional treatments like radiation or hormonal therapy have limitations. However, chemotherapy drugs often impact healthy tissue as well, leading to potential side effects such as nausea and hair loss.

In the case of antimicrobial chemotherapy drugs, they can be bacteriostatic (inhibit the growth of bacteria) or bactericidal (kill bacteria). The use of such drugs needs to be considered carefully to prevent superinfection and the development of antimicrobial resistance.
