Many plant pathologists believe that plant resistance is based upon the interplay of different signaling molecules? Justified.

Answers

Answer:

Yes.

Explanation:

Many plant pathologists believe that plant resistance is based upon the interplay of different signaling molecules because plants have various signaling molecules that plays a great role in their growth and development. Ethylene, auxin, cytokinins, gibberellins, and abscisic acid are the growth regulators that controls the growth of plants in different conditions i.e. in resistance. These signals leads the plant to take measures in difficult situations experience by the plants so in this way the plant is resistance to the harsh environmental condition.

a. The chromosomes in the cell become less tightly coiled.
b. The nuclear envelope disappears in the cell.
c. The mitotic spindle of the cell begins to form outside the nucleus.
d. The cell begins to elongate and the two poles have an equivalent collection of chromsomes.
e. The vesicles derived from the Golgi apparatus produce a cell plate at the middle of the cell that eventually forms the new cell wall.

Answers

Answer:

d. The cell begins to elongate and the two poles have an equivalent collection of chromosomes.

Explanation:

The cell cycle is a fundamental cellular process by which a parent cell divides into two or more daughter cells. In somatic cells, this cycle can be divided into two major phases: interphase, where the cell prepares for its division, and mitosis or 'M phase'. The M phase can in turn be divided into four stages: 1-prophase (also divided into early prophase and prometaphase), 2-metaphase, 3-anaphase, and 4-telophase. During prophase, chromatin condenses, thereby forming visible chromosomes. Subsequently, during metaphase, the sister chromatids (i.e., the two identical halves of a single replicated chromosome) align along the middle of the cell at the metaphase plate by attaching their centromeres to the spindle fibers. Next, during anaphase, sister chromatids are separated and move to opposite poles of the cell, pulled by the mitotic spindle fibers. At the end of anaphase, the microtubules of the mitotic spindle pull the two sister chromatids toward opposite poles, thereby the cell gets begins to lengthen. Finally, during the telophase, daughter chromosomes arrive at opposite poles and uncoil, while daughter nuclei begin to form at the two poles and nuclear envelopes are formed.


Which determines carrying capacity?

Answers

Carrying capacity, or the maximum number of individuals that an environment can sustain over time without destroying or degrading the environment, is determined by a few key factors: food availability, water, and space.

The availability of abiotic factors (such as water, oxygen, and space) and biotic factors (such as food) dictates how many organisms can live in an ecosystem.

The digestive and excretory systems project explaining macromolecules in the body

Answers

Answer:

Our digestive system has the ability to convert macromolecules into micromolecules.

Explanation:

Our digestive system has the ability to convert macromolecules into micromolecules with the help of certain enzymes. Carbohydrate is a macromolecule which is converted into glucose molecule with the help of saliva which is an enzyme present in the mouth, protein is also a macromolecule that is converted into amino acid so that our body cells can absorb it and fats are also macromolecules which can be converted into fatty acids with the help of digestive system. The cells produced waste materials such as carbondioxide gas and nitrogenous material which can be excreted through excretory system such as lungs and urinary bladder.

Determine which of the following statements is true about energy in ecosystems. A. Producers are able to convert 40% of the sun’s energy into chemical energy. B. 30% of the sun’s energy cannot be absorbed by producers because it is in the wrong wavelength of light. C. Producers only absorb 40% of the sun’s energy, most of which is lost during photosynthesis. D. Producers absorb 5% of the sun’s energy, and reflect 5% of the sun’s energy.

Answers

Answer:

A. Producers are able to convert 40% of the sun’s energy into chemical energy.

Explanation:

Energy in an ecosystem must be transferred in the ecosystem. The primary source of energy in an ecosystem is the sun. The terrestrial ecosystem mostly consists of plants and marine ecosystems. As energy flow in an ecosystem is unidirectional. It passed from the organism from one tropic level to another. Only 10% of the energy is available to them.

Answers

Explanation: Unlike the r-selected species, the size of the population of K-selected species is fairly the same with time. The r-selected species generally lies below the carrying capacity, and the size of the population is density-independent. On the other hand, the K-selected species are generally at or close to the carrying capacity and the size of the population is density-dependent.

Both starch and cellulose are made by stringing together many glucose molecules, but starch is easily digested by humans, while cellulose is indigestible. The starch polysaccharide has every bond occurring below the sugar rings while the bonds in cellulose alternate between one bond above the ring and the next below the ring. How can you explain humans' inability to digest cellulose

Answers

Answer:

See explanation

Explanation:

The ability of humans to digest starch and cellulose depends largely on the presence or absence of enzymes that can hydrolyze the starch or cellulose linkages thereby making it digestible.

Starch can easily be digested but cellulose can not be easily be digested because human beings lack the necessary enzyme responsible for hydrolysing the beta-acetyl linkages in cellulose. As a result of this, humans do not metabolise cellulose.

When observing a plant cell under a microscope, what parts do you think would be big enough to see?

Answers

Answer:

Explanation:

There are a few key structural differences between plant cells and animal cells.

Below are a few of the main ones:

Plant cells are generally larger than animal cells.

Only animal cells have lysosomes (however, recent, and controversial, research suggests that some plant cells may have lysosomes), and only plant cells have chloroplasts.

While plants cells have a rigid cell wall, animal cells have a thin and flexible plasma membrane.

Plants cells have a large central vacuole and animal cells have many small vacuoles

When observing a plant cell under a microscope, one can see large interlocking rectangular blocks. Around each cell, the cell wall is clearly visible. When stained, the cell wall is somewhat thick and visible. The cytoplasm is also lightly stained, with a darkly stained nucleus at the cell's periphery.

What is a plant cell?

A plant cell is a eukaryotic cell with something like a true nucleus and organelles that perform specific functions. However, some organelles found in plant cells differ from those found in other eukaryotic cells.

At the time of observing a plant cell under a microscope, person can see large rectangular blocks as well as cell wall is clearly visible.

When stained, the cell wall is thick and visible. The cytoplasm will also be lightly stained, with stained nucleus at the cell's periphery.

Solids, liquids, and gases are the forms. For example, the poles are cold, so the water at the poles are solid. When water is evaporated into the clouds or to make humidity, it is gas, and lastly when it rains or the body of oceans makes it liquid.
