if a plant is growing by incorporating carbon into its body, is the rate of photosynthesis or the rate of cellular respiration h
zheka24 [161]

Answer:

Rate of cellular respiration is higher.

Explanation:

Photosynthesis is a process in which plants makes its food. This food is very significant for the plant and those who eats these plants. The factors which affect photosynthesis ,light intensity,carbon dioxide  and temperature.

Light intensity: Without  enough light plant cannot photosynthesize even there is plenty of carbon dioxide and temperature.

If there is no light the carbon dioxide uptake is below Zero(0) With no light there is no photosynthesis.So the rate of respiration higher than the photosynthesis.

If the light intensity increased the rate of photosynthesis will also be higher and more carbon dioxide uptake by the plant during photosynthesis

Pseudohypertrophic muscular dystrophy is an inherited disorder that causes gradual deterioration of the muscles. It is seen almo
tankabanditka [31]

Answer:

This disorder is caused by a recessive allele, its inheritance is sex-linked.

Explanation:

The disorder affects boys born to unaffected parents, this means that at least one of them has to be a carrier of the allele which causes the disease. So, if the allele was dominant, it would express in parents and sons. But, in this case, only is expressed in sons, so it can´t be dominant. Moreover, this condition has a sex-linked inheritance because it is always seen in boys and never in girls. This happens due to boys only have an X chromosome, so if they inherit the recessive allele of the disease, they will express it. On the other hand, girls have two X chromosomes, so if they inherit one copy of the recessive allele, they will be carriers and they won't be affected.  

This disorder is never seen in females because they need to have two copies of the recessive allele. However, to have double copy, they should inherit one copy from their mothers and one copy of their fathers, but boys with the allele are affected and they die in early teens without having progeny.  Therefore, a girl can't have a "carrier-father", so they will never have two copies to express the disorder.

At a basic level mitosis and meiosis are similar processes. However, they have very different outcomes. Which of the following s
Dafna1 [17]

Answer: C. Homologous chromosomes are separated in meiosis but not in mitosis.

Explanation: There are two main types of division that take place in eukaryotic cells, mitosis, and meiosis. Mitosis is the type of division that is used for growth, repair, and replacement of tissues. Therefore it is not necessary that the cells have  different chromosome numbers or are varied genetically in the daughter cells in the case of mitosis.

Meiosis is the division that takes place to form the gametes for sexual reproduction. It is important in the first stages of meiosis I, to introduce variation and to halve the chromosome number.

Chromosomes numbers are halved (from 46 to 23) during meiosis I because the gametes (sperm and egg) come together and fuse during fertilization to form a zygote. When this fusion occurs (23 from the zygote and 23 from the egg), the chromosome number needs to be returned to that of the parent cell (46).

<h2>Genetic variation is introduced during synapsis which only occurs in meiosis, not mitosis. Homologs exchange genetic information during crossing over of synapsis. Entire chromosomes also separate during meiosis I. </h2>

At the end of meiosis, four genetically unique cells are  produced with half the number of chromosomes as the parent cell (23 cromosomes) . After the process of mitosis is completed, two cells genetically identical to each pther are produced and have the same number of chromosomes as the parent cell (46 cromosomes).

Genetic variation is actually important because of changing environmental conditions.
