Your answer would be the 3rd option, or C. Kudzu overgrows and crowds out native plant population, for sunlight and nutrients. Therefore, it's considered 'invasive' .

Hope this helps 'ya

<h2>Hello!</h2>

The answer is "Kudzu outcompetes native plants for sunlight and nutrients."

<h2>Why?</h2>

Kudzu vine is known as a fast-growing plant since the '30s and 40's when the Soil Conservation Service paid about 8$ to every farmer who can plant an acre with this plant.

Kudzu was used to prevent soil erosion caused by deforestation, especially in the south.

Erosion is known as a process that removes soil, rock or material, and it's caused by different naturals reason or human actions like deforestation, construction, and others.

Which of the following is not a sign of possible pest infestation?
Brrunno [24]

The right answer is smelly garbage.

Infestation is the penetration into the body of a parasite whose nature is not microbial.

smelly garbage is not synonymous of infestation, because the olfactory system only detected smelly metabolites of these microorganisms. This does not necessarily mean that the microorganism has managed to penetrate the body.

By cons other proposals are signs and tools for infestation (torn packaging with food leaking out, dead insect bodysuits, feathers, and fur).

Use the principles of diffusion to explain why oxygen molecules in the tissues of the lung go into the blood
Keith_Richards [23]

Answer:

Oxygen molecules in the tissues of the lung diffuse into the blood because the concentration of oxygen in the lung's tissues is more than the concentration of oxygen in the blood.

Explanation:

Diffusion is the movement of molecules from the region of higher concentration of the molecule to the region of lower concentration of the same molecule. Molecules in diffusion move <em>downward the concentration</em> <em>gradient</em> created by difference in concentration between two regions until an <em>equilibrium (equal concentration in the two regions)</em> is established.

Oxygen molecules diffuse into the tissues of the lung when an organism breathes-in during the process of breathing. The molecules in the now oxygen-rich tissues eventually start diffusing into the blood in the lung because the blood passing through the lung is always de-oxygenated or has lower oxygen concentration compared to the tissues of the lung.

Oxygenated blood moves into the heart, pumps round the body by the heart, gets depleted of oxygen and eventually find its way back to the lung where the process is repeated.

Diffusion of oxygen from the tissues of the lung into the blood will keep happening as long as oxygen keeps getting dissolved into the lung's tissues and an equilibrium is yet to be established between the tissues and the blood.

What is the layer of stem cells that constantly divide to renew the epidermis?
Mnenie [13.5K]

Answer: I think, I may be wrong, but I think the answer is stratum basale.  i <em>found this online</em>

Explanation: The topmost layer is dead and sheds continuously. It is progressively replaced by stem cells that divide in the basal layer (stratum basale). The dermis connects the epidermis to the hypodermis and provides strength and elasticity due to the presence of collagen and elastin fibers.

First-division nondisjunction will only yield gametes with an extra chromosome, whereas second-division nondisjunction will only
statuscvo [17]

False

Explanation:

  • During the meiosis, the cell is dividing two times and chromosomes are getting replicated. In this process, there can be errors. One of those errors is called nondisjunction.
  • As a result of the meiosis one, the cell gets divided into two cells and each will carry 23 chromosomes each. At this stage, These chromosomes are connected in the form of sister chromatids. During the meiosis two, these sister chromatids will pull apart and form four cells. Each one will be haploid cells. In meiosis one, chromosomes will undergo crossing over so this separation of chromosomes in the second meiosis is know as disjunction. However, in this process of separation, the chromosomes do not need to get distributed correctly. The errors that happened in this process are known as nondisjunction.
  • In humans, meiosis will happen and form sperms or eggs( gametes) which are haploid cells and later they combined to form a zygote which is the diploid cell.
