Answer:
Mitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase. Some textbooks list five, breaking prophase into an early phase (called prophase) and a late phase (called prometaphase).
1) Prophase: chromatin into chromosomes, the nuclear envelope break down, chromosomes attach to spindle fibres by their centromeres 2) Metaphase: chromosomes line up along the metaphase plate (centre of the cell) 3) Anaphase: sister chromatids are pulled to opposite poles of the cell 4) Telophase: nuclear envelope ...

Can you describe a frogs metamorphosis, including whether it is complete or incomplete
Answer: frig metamorphosis is complete
Explanation:
This is because in complete metamorphosis, frog develop from egg to adults. Metamorphosis refers to change of shape and growth in different stages of animals life cycle.
Frog mate in the rainy season.
There are four stages of frog metamorphosis and they are;
1 Egg : the female mate with the male and the male fertilizes the egg. The female releases the fertilized egg inside water , they egg are jelly like or cover with jelly covering.
2. Tadpole: the egg then hatched into tadpoles. The tadpoles live in water, it does not have lungs and limbs. It move like fish and uses gills to breathe. At this stage it starts developing hind limbs and later lungs. It has long tail
3. Froglet : At this stage, the lungs and the front legs develop. It floats above the water to breathe. The tail become shorter and it uses nutrients stored in the tail to feed or survive.
4. Adult : this is the final stage, the young frog leave water and start live on land, it's tail disappear completely and it's start feeding on insects.

Which plays a major role in determining which genes are expressed in a cell?
A. transcription factors
B.nothing, it is random
C.translating into spanish
D.your mother
Answer:
A.
Explanation:
A crucial component of controlling transcription is played by proteins known as transcription factors. These crucial proteins aid in identifying the genes that are active in each of your body's cells. Thus, option A is correct.
What is the role of transcription factors?Proteins called transcription factors control the expression of genes. They affect the transcription process, in which DNA serves as a template to create mRNA, which in turn affects protein synthesis.
Since many transcription factors are either tumor suppressors or oncogenes, cancer is linked to their mutations or abnormal regulation.
It is known that three transcription factor groups play crucial roles in human cancer.
Therefore, transcription factors play a major role in determining which genes are expressed in a cell.

Which explains the relationship between the respiratory system and the circulatory system in an organism?
A. The respiratory system takes in oxygen. The circulatory system delivers the oxygen to cells.
B. The respiratory system takes in oxygen. The circulatory system removes wastes from the body.
C. The respiratory system delivers oxygen to cells. The circulatory system controls the body's activities.
D. The respiratory system delivers oxygen to cells. The circulatory system provides support to cells.
A. The respiratory system takes in oxygen. The circulatory system delivers the oxygen to cells.
The respiratory system is defined as the set of tissues and organs involved in the uptake of oxygen from the atmosphere and the release of carbon dioxide produced during aerobic respiration.
This gas exchange is also called breathing or external respiration. Thus the correct option is A that is the respiratory system takes in oxygen. The circulatory system delivers the oxygen to cells.
In which system lungs and heart are present?Lungs are present in respiratory system and heart is present in circulatory system.
The circulatory system is refers to as which delivers oxygen and nutrients to cells and takes away wastes. The heart pumps oxygenated and deoxygenated blood through blood vessels which include arteries, veins and capillaries.

Explanation:
Marc and Dan are twins who like the same activities, and foods. At a recent doctor's appointment, Dan was told that he has type 2 diabetes. He has been feeling good and has not noticed any changes in his health. He does not understand why he has diabetes but this brother does not and why he has not had any noticeable symptoms. How would you explain this to him? Describe what the glycemic index is and how this is very important in developing a nutritional diet.
Answer:
The glycemic index allows people with diabetes to follow a balanced diet by consuming foods with a low glycemic index, which helps to avoid increasing the level of sugar in the blood.
Explanation:
The glycemic index is important to know when a certain food raises the level of sugar in the blood.
A good diet for people with diabetes is determined by foods that have a low glycemic index between 1 to 55; Some of the foods that can help us regulate the level of sugar in the blood are the following:
- Breads and cereals that are exclusively whole grains.
-Legumes like beans and lentils.
-Fruits such as: peach, pear, apples, cherries and prunes.

production
True
False

Answer:
True
Explanation:
A vesicle is used in the production of proteins in the cell. The given statement is true. Proteins are produced in the endoplasmic reticulum and processed and packaged in the vesicles.
What is Protein production?A protein is synthesized in the ribosomes of rough endoplasmic reticulum. These proteins are translated from the mRNA which contains the genetic sequence that codes for specific proteins.
The proteins synthesized in ribosomes will then undergo post-translational modifications in the golgi apparatus, and are transported in the form of vesicles to their particular destinations.
The vesicles act as containers which carry the proteins from the organelle where the proteins are produced (rough endoplasmic reticulum) to the destination i.e., plasma membrane.

How does a flowering plant's anther help its species survive?
o It produces food for the plant
O It produces pollen for reproduction.
o it anchors the plant in the ground.
It helps the plant protect itself.
HELP
Answer: It produces pollen for preproduction
Explanation:
An anther of a flowering plant help in the survival of its species by producing pollen for reproduction. Thus, the correct option for this question is B.
What is the function of the anther in flowering plants?The fundamental and the most important function of the anther is to produce and provide the pollen, the pollen-containing anther acts as the sperm that is necessary for reproduction. It is characterized as a male reproductive part of a flower.
Apart from the anther, the Stigma is the female reproductive part of a flower. The connection of these two attributes may an essential role in reproduction. The anthers are bilobed with sac-like structures (microsporangia) present inside them. The stigma is a receptive base on which the pollen lands.
Therefore, a flowering plant's anther helps its species survive by producing pollen for reproduction. Thus, the correct option for this question is B.

Answer:
B. The chimp and human are the most closely related organisms with the fewest differences in their amino acid sequence
Explanation:
This question shows a table containing the amino acid sequence of haemoglobin protein in different organisms. According to the table attached, a total of 15 amino acids are represented for each organism. A very reliable evidence that shows the relationship between organisms i.e. how related they are, is their DNA SEQUENCE.
Since the amino acid sequence of the protein in an organism is determined by the DNA sequence, organisms with very similar amino acid sequence are said to be CLOSELY RELATED. Hence, the similar the DNA sequence, the closer the relationship between organisms. In this case, the chimp and human have the same set of amino acids in their sequences, hence, they are the most closely related organisms with the fewest differences in their amino acid sequence.
