During which stage of the cell cycle does the cell condense chromosomes and break down the nuclear envelope? anaphase prophase metaphase telophase
Answers
During prophase of the cell cycle, the cell condenses its chromosomes and breaks down the nuclear envelope.
A cell cycle, also known as a cell-division cycle is defined as a series of events which take place in a cell as it is growing and dividing in order to form two daughter cells. A cell cycle has a few different stages namely prophase, metaphase, anaphase and telophase.
Prophase is the first stage of both mitosis as well as meiosis. In the prophase, the chromatin which is present in the cell is condensed in order to form chromosomes. The nuclear envelope, which is the membrane which surrounds the nucleus of the cells also starts breaking done.

What are the hereditary diseases?
Answers
Sickle cell anemia, cystic fibrosis, and hemophilia are some of the hereditary diseases that occur because of changes in the genetic make of an organism.
Hereditary diseases usually referred to as inherited diseases or genetic disorders, are a group of genetic diseases that are brought on by changes in a person's genetic makeup (DNA). These changes are caused by mutation. This occurs when the normal bases in the DNA is replaced with the faulty base or mismatched base.
Then, these illnesses are passed down from one generation to the next, or in other words, they are inherited from one set of parents to another. For example, sickle cell anemia, cystic fibrosis, and hemophilia are some examples of hereditary diseases.
Because sickle hemoglobin requires two copies of the gene to be present, sickle cell anemia is referred to as a recessive condition. They must get one from each parent, which code for abnormal hemoglobin.

What does gene expression control?
a. the proteins that are made by the cell
b. the rate at which DNA replication occurs
c. the duration between cell cycles
d. the division of the cell nucleus
Answers
Answer:
a
Explanation:
Control of gene expression ,
1)Transcriptional control : controls when and how often the gene is being transcribed.
2)Post-transcriptional control :
- RNA process control determines how often RNA is been processed.
- RNA transport and location control : selection of mRNA to be transported to
cytosol.
- mRNA degeneration control ; selection of which mRNA is getting destabilized.
3)Translational control ; section of which mRNA is being translated.
4) Protein activity control / post-translational control ; regulation of proteins by activation , deactivation, degeneration, compartmentalization and modification of protein.
Gene expression control the proteins that are made by the cell. So, the correct option is A.
What is Gene expression?Gene expression is the procedure through which a gene's information is used to create a functioning gene product, allowing it to produce end products like proteins or non-coding RNA and ultimately have an impact on phenotypes.
A finely controlled process called gene expression enables a cell to react to its changing surroundings. It serves as both a headphone jack that raises or lowers the level of proteins produced as well as an on/off switch to regulate when proteins are created. Transcription and translation are the two essential processes that go into the creation of a protein. Gene expression control the proteins that are made by the cell.

Because the human embryo is able to split during early cleavage or blastocyst formation to produce two viable progeny, it is said to exhibit _______ development.
Answers
Answer:
This question lacks options, options are:
a) indirect
b) mosaic
c) determinative
d) regulative
e) direct.
The correct answer is d.
Explanation:
The egg (ovum) like the embryo during the first embryonic divisions, do not possess any sign of polarity. This development mechanism can be called regulative development(in contrast to the mosaic model) since the fate of the cells that originate is not fixed and can be modified during development. In regulative embryos, part of the embryo can be removed and the remaining cells can compensate for the loss and give a complete individual as the final product.The strongest evidence that continues to support this regulatory model is based on the plasticity or potential that mammalian cells possess before implantation. It is known that the blastomeres produced by the first divisions can be replaced with each other or even can be eliminated without apparently altering the embryonic development and therefore they are equivalent (without polarity).

The stomach lining is able to heal itself the fastest, followed by the skin, and then the liver.

The stomach lining is the innermost layer of the stomach, made up of cells that produce digestive enzymes and secretions that help break down food. This layer also helps protect the stomach from the acidic environment within the stomach.
The stomach lining is able to heal itself quickly because it contains specialized cells that can quickly make new tissue to replace damaged cells. The skin is also able to heal quickly because it is made up of many layers of cells that can quickly reproduce to form new skin. The liver is able to regenerate itself, but it takes longer than the stomach lining or skin because the liver is made up of fewer cells and the process of regeneration is more complex.

Explain how the result show that both light and chlorophyll must be present for photosynthesis.
Answers
Chlorophyll absorbs energy from blue and red light waves during photosynthesis while reflecting green light waves, giving the appearance of a green plant.
Chlorophyll, a light-absorbing pigment found in the thylakoid membranes of the chloroplast, is what gives plants their green hue. Chloroplasts, which are tiny organelles found inside plant cells, are there to store solar energy. Despite the fact that there are numerous steps involved in photosynthesis, there are primarily two stages: light-dependent reactions and light-independent reactions. The light-dependent reaction, as its name implies, occurs inside the thylakoid membrane and necessitates a constant supply of sunshine. The light waves' energy is captured by the chlorophyll and transformed into chemical energy in the form of the molecules ATP and NADPH.
The Calvin Cycle's light-independent stage, which takes place in the stroma, or region between the chloroplast and thylakoid membranes, does not require light, hence the name light-independent reaction. In this phase, carbon dioxide is converted into carbohydrates like glucose using energy from the ATP and NADPH molecules. However, not all types of photosynthesis are made equal. C3 photosynthesis and C4 photosynthesis are two of the various forms of photosynthesis. The majority of plants engage in C3 photosynthesis. It entails the Calvin Cycle producing 3-phosphoglyceric acid, a three-carbon molecule that later transforms into glucose.

Explanation: do you want one?
Growing crops does not raise the carbon levels and does not cause global warming ; ( i.e. the statement in the question is False ).
Crops/plant make use of carbon dioxide in the atmosphere during photosynthesis, releasing oxygen and energy into the atmosphere as a by product from photosynthesis.
Global warming is caused by the presence of green house gases in the atmosphere and the removal of CO₂ by plants from the atmosphere during photosynthesis helps with reduction of a green house gas ( CO₂ ).

Neurotransmitter molecules penetrate the synaptic cleft and attach to receptor proteins on postsynaptic cells.
Synapses can be thought of as converting an electrical signal (the action potential) into a chemical signal in the form of neurotransmitter release, and then switching the signal back into an electrical form when the transmitter binds to the postsynaptic receptor.
These stimulate the production of "neurotransmitters," which pass the impulse across the "synapse to the next neuron." After a nerve impulse releases "neurotransmitters," these "chemical messengers" travel over the tiny "synaptic gap" and are taken up by specialized receptors on the surface of the next cell.
