No plagiarizing from websites!
Many people feel the use of stem cells has great potential for scientific and medical progress, while others have been opposed to it. Today there is a great deal of debate about stem cell research using pluripotent stem cells from an embryo. Provide an argument for people in favor of continuing stem cell research. Include in your answer the uses of stem cell research and a suggestion for obtaining a source of stem cells without risk to life. (2 points)

Answers

Answer:

Stem cells can benefit humanity in a variety of ways, one, being the ability to develop into another cell. This is remarkable for people who have diseases and or health issues, requiring them to replace cells that they lack. Not only that, but they help treat diseases like stroke, heart disease and diabetes.

How can a shortage of nutrients harm organisms in an ecosystem? How can an excess of nutrients harm organisms in an ecosystem? Give an example of each scenario to support your answers.

Answers

Answer:

Explanation:

Shortage of nutrients in an ecosstem can harm an organism because when nutrients are scarse or very limited for organism and did not meet up with the organism requirements, there will be reduced metabolism and this can cause malfunction. Shortage of nutrients can lead to decline in growth and can lead to spring up of some diseases in the organism because enough nutrients us not available for good metabolic processes and fight diseases.

For example when an organism is deficient in vitamins and carbohydrates, the organism will not have energy to power metabolic processes and for it's activities and vitamins deficient will make the organism not to have the ability to fight against disease.

Too much of nutrients also affect organisms negatively. When there is much build up of nutrients, it can be harmful to the organisms and restrict metabolic processes.

For example too much of nutriwnts like too much of fat can block blood artieries and veins and thus can lead to inability of blood to flow .

Which two structures produce energy that cells can
use?
O A and B
OB and C
O Cand D
O D and A

Answers

Answer:

According to the plant cell scheme, the two structures that produce energy that cells can use are D, which corresponds to mitochondria, and A, which is a chloroplast, so the answer is D and A (fourth option).

Explanation:

In the plant cell —unlike the animal cell— there are organelles called chloroplasts, responsible for converting light energy from the sun into chemical energy. In addition, there are mitochondria, which also provide useful energy to the cell.

In the chloroplast, photosynthesis takes place, a process that during the light phase produces ATP and NADPH⁺ from solar energy. In the mitochondria, energy in the form of ATP is obtained from glucose, due to oxidative phosphorylation and the electron transport chain.

The organelles indicated in the diagram are mitochondria (A) and chloroplast (D), both responsible for producing energy for the plant cell.

The dendrites branch out, forming “dendrite trees” that can receive signals from many other neurons when babies get mature.

If a plant with chlorosis is unable to perform photosynthesis, what products (include
BOTH) are not being made?

Answers

Answer:

Glucose and oxygen

Explanation:

Photosynthesis is the process by which the cells of green plants synthesize their own food in the presence of sunlight. Although photosynthesis consists of various steps, it generally combines carbon dioxide (CO2) and water (H2O) to produce glucose (sugar) and oxygen gas (O2). The equation is as follows:

6CO2 (g) + 6H20 (l) → C6H12O6 (aq) + 6O2(g)

In a plant that possess chlorosis (a condition characterized by yellowing of leaves due to lack of chlorophyll), photosynthesis will not occur. This ultimately means that the photosynthetic products such as GLUCOSE AND OXYGEN WILL NOT BE MADE.

Describe the events that occur during the cell cycle. Include what happens in each of the following stages: interphase, mitosis, cytokinesis.

Answers

Answer:

Cell cycle or cell division refers to the series of events that take place in a cell leading to its maturity and subsequent division. These events include duplication of its genome and synthesis of the cell organelles followed by division of the cytoplasm.

interphase-During interphase, the cell copies its DNA in preparation for mitosis. Interphase is the 'daily living' or metabolic phase of the cell, in which the cell obtains nutrients and metabolizes them, grows, reads its DNA, and conducts other "normal" cell functions. This phase was formerly called the resting phase.

mitosis-In cell biology, mitosis is a part of the cell cycle, in which, replicated chromosomes are separated into two new nuclei. Cell division gives rise to genetically identical cells in which the total number of chromosomes is maintained.

Cytokinesis-Cytokinesis is the division of the cytoplasm in eukaryotic cells that produces distinct daughter cells. Cytokinesis occurs at the end of the cell cycle following mitosis or meiosis. In animal cell division, cytokinesis occurs when a contractile ring of microfilaments forms a cleavage furrow that pinches the cell membrane in half.
