Answer:

Explanation:
Plants, algae, and some kinds of bacteria have the ability to photosynthesize. They have special organelles called chloroplasts.
These organelles are the site of <u>photosynthesis</u>. They contain green pigment known as chlorophyll which can capture sunlight. The light energy plus carbon dioxide and water are converted into glucose and oxygen.
The glucose becomes the organism's food and energy source, but the oxygen is just released as a waste product.
A drosophila mutant that has legs instead of antennae in its head is caused by a mutation in the phenotype is most likely found in the homeotic genes. The homeotic genes are the one responsible in regulating or formation of the structures in animals. This is likely where the mutation is found, causing the drosophila have legs on its head.
Answer:
The correct answer is option c. "cell interactions".
Explanation:
Cell-to-cell interactions, or only cells interactions, refers to the mechanisms that cells have to communicate among them. These mechanisms takes place at the surface of the cells by sending and receiving signals in receptors, which later initiate transduction pathways. Cell interactions play a crucial role in the development of embryos, therefore if a knockout mouse has embryonic lethality due to a disruption in a receptor, it is very likely that the development process that is affected is related with cell interactions.
Answer: Oxygenate
An aerobic environment is characterized by the presence of free oxygen (O2) so In order to live in aerobic conditions an organism must have oxygen or need to oxygenate.
In an aerobic conditioning, <span> the heart and lungs of an organism are conditioned or trained to pump blood more efficiently, in order for more oxygen to be delivered to muscles and organs of the body. It strengthens the heart and lungs or our cardiovascular system.</span>
