Cells with large numbers of mitochondria have a high energy demand
tigry1 [53]3 years ago
7 0

Answer:

Mitochondria is a double membrane organelle which is involved in the production of energy molecules of the cell called adenosine triphosphate or ATP.

The number of mitochondria in a cell is dependent on the function of the cell it is specialized to perform. For example:

1. The number of mitochondria in a muscle cell is very high as it requires a high amount of ATP molecules for contraction.

2. Mature red blood cells lack nucleus as they are specialized to perform carry oxygen molecules and do not require the ATP.

Thus, the number of mitochondria depends on the function of the cell.

How can one set of parents produce 19 children who all look different and unique but yet have some similar characteristics or tr
arsen [322]

Polygenic inheritance. The characteristics of a person aren't controlled completely by a single gene, but rather several genes that generally only make a small contribution to how the child turns out in the outcome. At one point there was a study that showed over 400 genes were linked to height, so imagine any other characteristics of a person. Environmental effects also serve a large purpose in how a child is to turn out. These children may all be growing up in the same environment, however that's not to say they all grow up the same. They could all be treated the same way and react differently to it, this counts both for physical and mental traits. All human's features such as eye colors, hair color and height are determined by several different genes. As an example, there are around 2 major eye color genes, however there are also around 14 different genes that actually contribute in determining a person's exact eye color. Some are bound to look the same, as they have the same parents, however, just because they have the same parents doesn't mean they all will look exactly alike.

H2SO4 + NaOH → Na2SO4 + H2O
Ronch [10]

Answer:

Answer

4.0/5

4

Explanation:

The balanced chemical equation will be;

H2SO4 + 2NaOH → Na2SO4 + 2H2O

The equation for the reaction is balanced by using coefficients; 1,2,1,2

According to the law of conservation of mass the mass of the reactants should be equal to the mass of the products.

For the law of conservation of mass to be obeyed, chemical equations must always be balanced.
