Which of the following statements about the smooth endoplasmic reticulum is/are correct?
olya-2409 [2.1K]

The correct answers are:

• Liver cells are abundant in SER.  

This is because liver cells contain enzymes that metabolize various lipid-soluble compounds.

• The testes and ovaries are tissue types whose cells are abundant in SER.

This is because testes and ovaries produce steroid hormones (cholesterol is the precursor for their synthesis).

• Cholesterol is made in the SER.  

ER is the organelle at which all membrane lipids are synthesized.

• Phospholipids are synthesized from cytosolic water soluble precursor molecules.  

Phospholipids are the main lipids that are the main structural components of the cell membrane. They are synthesized on the cytosolic side of the ER membrane, from water-soluble cytosolic precursors.

Why are there fewer organisms in each level as you go up the energy pyramid ​
SVETLANKA909090 [29]

Explanation: The energy pyramid describes how energy gets distributed through an ecosystem. The more there is of an organism on the energy pyramid, the more it gives overall to the ecosystem. The less there is of an organism, the less it gives to the ecosystem. Take the Floridian Everglades as an example. There is an abundance of sawgrass, and that makes up the foundation of the system, along with mangroves and such. But there are less of predators in the ecosystem because they only feed of of their prey like small mammals or fish. They never start the food chain, they end it.

3. In one population, 18 individuals have long hair and 182 individuals have short hair. It is known thatmating has been random
pishuonlain [190]

Answer: p (short hair) = 0.91 and q (long hair) = 0.09

Explanation: In the population, short hair is a feature of domnant allele, because there are more short haired individuals than with long hair. In genetics, p is the frequency for dominant allele and q is for recessive allele.

For this question, short hair is allele L and long hair is allele l

So, the frequency of short hair is p and of long hair is q.

To calculate the frequencies:

Frequency of allele L = (number of copies of allele L in population) / (total number of L/l gene copies in population)

p = 182/200 = 0.91

The same formula goes for the recessive allele, so:

q = 18/200 = 0.09

Thus, the frequencies of hair allele are 0.91 and 0.09 for short and long, respectively.
