Answer:

<u>A focal infection</u> is a small region of infection, from where the pathogen can move to other areas of the body to cause a secondary infection.      

Explanation:

The focal infection theory is a theory that states that many chronic diseases (such as cancer, arthritis, mental illness) are caused by a focal infection. A focal infection is a small region of infection or a localized infected region, which can lead to a secondary infection at a site, which is susceptible to infections. Examples of such focal regions are nasal sinuses, kidney, gall bladder, liver, etc.

<u>Therefore,</u><u> a focal infection </u><u>can be defined as a small region of infection, from where the pathogen can move to other areas of the body to cause a secondary infection</u>.

ANEK [815]

Answer:

Cell membrane of prokaryotes and Inner mitochondria of eukaryotes

Explanation:

Electron transport chain is a part of oxidative phosphorylation which is the third step of aerobic cellular respiration in living organisms. The ETC is a complex of proteins and mobile electron carriers. It occurs when electron is being transferred from one electron carrier to another, starting from NADH and FADH2. A proton pump which is used to synthesize ATP is generated at the end.

This ETC process occurs in the cell membrane of prokaryotic cells due to the fact that they lack a membrane-bound Mitochondrion. ETC occurs in the inner membrane of the mitochondria called CRISTAE in eukaryotic cells.

Write an 2 paragraphs about germination! PLEASE ASAP ☹
balu736 [363]

Germination is a process where plants and other organisms emerge from gymnosperm/angiosperm seeds and start their growth. Gymnosperms are seeds that are not protected by an ovule. Angiosperms are vascular plants that grow fruit and flowers, which are protected by ovule. Sprouting of a seedling from a seed is an example of germination. Fully developed seeds contain an embryo, that store food reserves and are wrapped in the seed coat. Some factors of successful germination include water, oxygen, temperature, type of soil, and light intake.

Mia conducted a five hour experiment. She used a liquid solution. The solution decreased by 9/8 ounces every hour for 5 hours. A
sasho [114]

Given:

The solution decreased by \dfrac{9}{8} ounces every hour for 5 hours.

Remaining solution at the end of the experiment = \dfrac{99}{8} ounces.

To find:

The initial amount of solution.

Solution:

Let the initial amount of the solution be x.

The solution decreased by \dfrac{9}{8} ounces every hour for 5 hours.

Total decreased amount  =\dfrac{9}{8}\times 5

                                          =\dfrac{45}{8}

Initial amount = Remining amount + Decreased amount of solution.

x=\dfrac{99}{8}+\dfrac{45}{8}

x=\dfrac{99+45}{8}

x=\dfrac{144}{8}

x=18

Therefore, the initial amount of solution is 18 ounces.
