Answer:
Four daughter cells are Asexual
The correct option is A.
During cellular respiration, sugar is broken down to carbon dioxide and water with the production of energy, which is use to drive the biochemical activities of the cell. The energy produce is always in the form of ATP. Complete oxidation of one molecule of glucose usually produce 38 ATP, this shows that, the mass of glucose is conserved in the cellular respiration reactions. <span />
The correct ones are:
- Differential gene expression affects the developmental process in animals.
- Positional information controls pattern formation.
- Homeotic genes code for transcription factors that control the development of segment-specific body parts.
- Cells receive molecular signals that communicate their position in relation to other cells.
Gene expression is the process by which information from a gene is used in the synthesis of a functional gene product, allowing it to produce end products such as protein or non-coding RNA and, as a result, affect a phenotype.
A homeotic gene is any of a group of genes that control the pattern of body formation in organisms during early embryonic development. These genes encode proteins known as transcription factors, which direct the formation of various body parts.
Molecular signaling refers to molecules that transmit information between cells in the body. However, the molecular properties of signaling molecules can vary greatly.

Answer:
A. Diffusion This type of transport requires no energy for it to occur.
For example, if someone on the other side of the room lets a silent fart out there is no need for anyone to use their energy for those fart particles to reach your nose, it just happens... same with diffusion. it will happen, just give it time.
Answer:
Pleiotropy
Explanation:
<em>Pleiotropy is a genetic term used to describe a phenomenon in which multiple traits or phenotypic expressions are dictated by a single gene. </em>
<em>Pleiotropy </em>was first discovered by Mendel during his experiment with pea plant when he noticed that flower colour is always related to the leaf axil as well as seed coat colour.
There are different types of pleiotropy including:
- Gene pleiotropy
- Developmental pleiotropy
- Antagonistic pleiotropy
- Selectional pleiotropy
In the case of marfan syndrome, inheritance of a single allele results in tall and long limb, cardiovascular and eye defects. This thus means that that single allele which represents a gene is responsible for expression of those traits. A clear cut case of pleiotropy.
