What a Stem Cells?

Stem cells are the body's raw materials- cells from which all other cells with specialized functions are generated.

What are specialized cells?

Specialized cells perform specialized functions in multicellular organisms. Groups of specialized cells cooperate to form a tissue, such as a muscle.

What are unspecialized cells?

An unspecialized cell that can give rise to one or more different types of specialized cells, such as blood cells and nerve cells.

Do you think stem cell research should be allowed?

By watching stem cells mature into cells in bones, heart muscle, nerves, and other organs and tissue, researchers and doctors may better understand how diseases and conditions develop.

What is the energy brought by electron carriers to the<br> mitochondria used for?
Nonamiya [84]

Answer:

The correct answer will be- to synthesise the ATP molecules in respiration process.

Explanation:

The electron transport chain is the last phase of the cellular respiration which helps in the synthesis of a large number of ATP molecules.

The ATP molecules are synthesized when the energy generated by the movement of protons through CF₀ unit takes place.

The movement of electrons in the chain leads to the movement of proton from the mitochondrial matrix to the intermembrane space. This creates the proton gradient across the membrane which to equilibrate the protons move down the concentration gradient through ATP synthase. The energy while this is used to rotate the ATP synthase which coverts the ADP to ATP.

Thus, to synthesise the ATP molecules in the respiration process.

In watermelons, solid green rind color (G) is dominant to stripes (g).
stiks02 [169]

There are chances of 75% solid green coloured rind in watermelons.

Explanation:

Dominant trait = Solid Green rind G

Recessive trait= stripes g

Given that both the parent plants are heterozygous so their alleles will be

Gg Gg

From the Punnet square

          G        g

G      GG     Gg

g       Gg     gg

The phenotype ratio is 3:1  ( 3 watermelons with the green colour rind and 1 with striped rind observed)

Genotype ratio is 1:2:1

From the observation, we can say that 75% of the watermelons will have solid green colour rind because G is dominant over g.
