Answer:

B. transporting substances in a cell

Explanation:

Endomembrane system is basically a system or organelles and membranes in eukaryotic cells, which is involved in packaging, modifying and transporting the proteins and lipids across the cell.

Many organelles and membranes play role in this system like lysosomes, endoplasmic reticulum, Golgi bodies and nuclear membrane.

Note: Chloroplasts, Mitochondria and peroxisomes are not part of endomembrane system.

You can see figure depicting endomembrane system for better understanding.

In the above diagram of a plant cell, what is the function of structure 3?

kramer

Explanation:

B. serves as the control center of the cell and contains the cell's genetic information

All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly wounucleuscarbohynd around histones as chromosomes. Chromosomes within the nucleus is unwound, unzipped and read by enzymes in a complex series of steps known as transcription. The message on DNA, called genes is copied by RNA polymerase, to form mRNA complementary sequence to that of the DNA strand. These are then translated into proteins in ribosomes.

Further Explanation:

A cell's structural components (i.e. their makeup) determine their function (what they do) . For instance, photosynthesizing cells in algae and plants have structures called chloroplasts. These contain chlorophyll, a specialized compound which facilitates the conversion of light energy to energy stored in carbohydrates. In specific cell types, collected proteins may function as a unit called an organelle. Some organelles are bound by membranes like those that make up the external structure of the cell, with varying compositions of phospholipids and proteins. These are advantageous, as they:

may increase metabolic reaction efficiency; they allow cells to concentrates smaller fractions of enzymes and solutes
separate proteins and molecules that me harm the cell by parceling them into membrane-bound organelles for example, proteaseas bound within lysosomes can break down many structural proteins

2. Dominant trait: cleft chin (C) Mother’s gametes: Cc

kakasveta [241]

Answer No 2:

c c

C Cc Cc

c cc cc

The genotype of the offsprings would be Cc, Cc, cc, cc i.e heterozygous cleft chin and no cleft chin. The phenotype of the offsprings could be 50% cleft chin and 50% without cleft chin.

there will be 50% chance of the child to have cleft chin.

Answer No 3:

A a

A Aa Aa

a Aa aa

There will be 25% chance for the offspring to have arched feet. As arched feet is a recessive trait, so for this trait to occur both the alleles of the gene should be recessive i.e aa.

Answer No 4:

B b

b Bb bb

As blonde is a recessive trait, so both the alleles for this gene should be recessive for this trait to occur. Hence, according to the punnet square, there will be 50% chance for the offspring to be blonde.

Answer No 5:

F f

F FF Ff

f Ff ff

As normal vision is a resessive trait, hence both the alleles of the gene should be recessive for the trait to occur. According to the punnet square, there is 25% chance that the child will have normal vision.
