Which structure is found in the cytoplasm of
a typical plant cell?
A.vacuole
B. cell wall
C.chloroplast
D.cell membrane​

Answers

Answer:

Explanation:

D

The structure that is found in the cytoplasm of plant cell is vacuole. The correct option is A.

What is vacuole?

A vacuole is a cell organelle that is membrane-bound. Vacuoles are relatively tiny in animal cells and help to sequester waste material.

Vacuoles in plant cells aid in keeping water balance. A single vacuole can sometimes take up the majority of the interior space of a plant cell.

Within the cytoplasm of plant cells, there are also large, fluid-filled vesicles known as vacuoles.

Vacuoles typically make up about 30% of the volume of a cell, but they can fill up to 90% of the intracellular compartment.

Vacuoles are used by plant cells to regulate their size as well as turgor pressure.

Vacuole is a structure found within the cytoplasm of plant cells.

Thus, the correct option is A.

Answers

Answer:

anatomy and neurobiology

Explanation:

Molecular Biology is the field of biology that studies the composition, structure and interactions of cellular molecules – such as nucleic acids and proteins – that carry out the biological processes essential for the cell's functions and maintenance.

Successful molecular biologists have an excellent understanding of subjects such as cell physiology, chemistry, genetics, and physics.

A neuroscientist (or neurobiologist) is a scientist who has specialised knowledge in the field of neuroscience, the branch of biology that deals with the physiology, biochemistry, psychology, anatomy and molecular biology of neurons, neural circuits, and glial cells and especially their behavioral, biological, and psychological aspect in health and disease.

Anatomy and neurobiology are the best for what he wants to do

To melt the ice during the winter season, road crews often put sand and salt solutions on the roadways to help melt the snow and ice. The plants that live close to the road often die or wilt after this procedure. Using your knowledge of osmosis and plant structures, which type of solution would cause this to happen to plant cells? Group of answer choices

Answers

Answer:

The missing answer choices are:

a. hypotonic

b. isotonic

c. osmosis

d. hypertonic

The correct option is d. hypertonic

Explanation:

A hypertonic solution has a higher concentration of solutes than the concentration of solutes present inside the plant. As there is a difference in concentration between the inside and the outside of the plant, the plant loses water in an attempt to balance the difference. As a result, there is an excessive loss of water that dehydrates the plant and kills it.

Answers

Answer:

25%

Explanation:

If a parent is heterozygous, it has 2 difterent alleles. Both parents are heterozygous for blood type A, so the genotype is AO. A masks the O because A is dominant over O, so A is the blood type.

Create a punnett square to find possible offspring

AA = Blood type A

AO = Blood type A

OO = Blood type O

There is 1 child out of 4 that have blood type O. So to find the percentage divide 1 and 4 and multiply by 100.

Interferons Interferons reduce macrophage chemotaxis to the infection. interfere with viral replication. prevent viruses from entering a cell. bind to viruses and destroy them. prevent viruses from leaving a cell.

Answers

Answer:

interfere with viral replication

Explanation:

Interferons (IFNs) are proteinous molecules, which are part of the innate immune system of our body. Interferons are produced in response to viral infections and they often specialize in preventing the virus pathogen from replicating or multiplying in the host cell.

As their name implies, INTERFERONS interfere with the replication of viral pathogens, hence, preventing the virus from further invading the host cell. This is done at the innate immunity level.

A. Co-species
B. Intraspecies
C. Interspecies
D. Habitat

Answers

Answer:

B.

Explanation:

In an ecological environment living things of different or same species compete with each other for the limited resources available. It is a symbiotic interaction between these living things.

There are two types of competition between these living beings- intraspecific and interspecific. In the given scenario, it is an intraspecific competition between the monarch butterfly and the queen butterfly.

Intraspecific competition is a competition between two living beings of the same species.

The monarch butterfly and the queen butterfly both belong to the same species- danaus.

Which class of point mutation produces a product with the same amino acid sequence as the wild-type polypeptide?

Answers

Answer:

The correct answer is - silent.

Explanation:

Silent mutation is a point mutation that takes place by a single change in a single base nucleotide of nucleic acid and it may or may not change the aminoacid sequence as the wild type protein.

This does not result in any phenotypic or functional change in the protein of the organism. It is a class of point mutation. This change can be substitution in base.

The leaves of this plant contain a thick gel that is quite bitter, but contains a protein that has 18 of the 20 amino acids found in the body, as well as Vitamins A, B, C and E and a complex carbohydrate known as acemannan that delivers nutrition to cells and detoxifies them.

This gel can be applied to skin to moisturise it, exfoliate it and prevent acne. It can also be applied topically to injuries, minor cuts, dry skin and severe burns. Applying it to one's hair and scalp prevents itching and dandruff and reduces hair fall. Drinking the juice (mixed with some other fruit juice, since it’s too bitter by itself) treats constipation and acidity, and improves blood sugar levels. Drinking the juice regularly also promotes weight loss.

why is it important for plant's to store food?​

Answers

Answer:

Storing the food helps them to use it in winter and survive because there is very little sunlight available and so they photosynthesis less. ... When they have extra food they store it in their seeds and when the seed grows it gets it's food from the plant until the plant is able to photosynthesis and produce its food.

Answer:

It's important for plants to store food, as food is a source of nutrition, which is necessary for survival. Rather than just eating the food, storing it is a good way to ensure nutrients during droughts or other harsh conditions that make it hard to find food.
