Biology
1 answer:
allochka39001 [22]3 years ago
4 0

Answer:

a) Radius decreases

Explanation:

Resistance of any conductor is directly proportional to the length of the conductor and inversely proportional to its cross-sectional area.

So, in mathematical terms, the resistance is written as

R = ρ \frac{L}{A}

As we know, cross sectional area is related to the radius of the conductor so if the radius of the conductor is decreased, the cross-sectional area will also decrease.

And if the cross-sectional area will decrease, the resistance will increase.

Thus decreasing the radius, increases the resistance.

Answer:

Lack of food sources, the lack of habitat, competition and evolving ways to compete.

Explanation:

Lack of food sources, the lack of habitat, competition and evolving ways to compete are the ecological conditions that is responsible for the rapid diversity of some lineages. With the passage of time, changes occurs in the lineages due to climate change which causes some species to extinct and some to evolve which attains adaptability to the environment. Due to climate change food is unavailable to the organisms which is the main cause of its extinction.

Answer:

1. Embedded in the plasma membrane

2. There is no diagram attached but the question can be answered based on general knowledge. The answer is Golgi apparatus/body.

Explanation:

1. Cholesterol is fat molecule produced in the Smooth Endoplasmic reticulum of animal cells. It is then transported to the plasma membrane, where it plays a vital role in the functionality of the plasma membrane. Hence, embedded in the plasma membrane of an animal cell is CHOLESTEROL, in addition to phospholipids.

2. The Golgi apparatus is an organelle in eukaryotic cells that functions in the modification and packaging of protein and lipid molecules produced by the RER and SER respectively.
