Answer:
chlorophyll
Explanation:
The mechanism by which light energy can be transformed into chemical energy by synthesis of organic compounds is chlorophyll, a member of the most significant pigment class involved in photosynthesis. In nearly all photosynthetic species, e.g. green plants, cyanobacteria and algae, the use of chlorophyll is identified. It consumes light energy and is then used for the conversion to carbohydrates of carbon dioxide.
The answer is the last option. both a and b are correct
Answer:
The phenotype may change constantly throughout the life of an individual because of environmental changes and the physiological and morphological changes associated with aging. Three types of natural selection, showing the effects of each on the distribution of phenotypes within a population.
The expected e heterozygous phenotype would be orange.
Codominance is a type of non-Mendelian inheritance in which both alleles of one genotype are simultaneously expressed. So, in this example if allele A is responsible for red flower color and allele a for yellow flower color, Aa genotype (both alleles) will give both colors (red and yellow mixed together give orange).
When a signal molecule binds a membrane receptor, different intracellular events occur in response. Option D is correct: All of the above.
<h3>
What is signals translation and how is it done?</h3>
Signal translation is the conversion global process of extracellular signals into intracellular responses. This porcess is done by a translator.
Translation might be
- INDIRECT ⇒ <u>Second messengers</u> participate in the signal translation, mediating between receptor and the cellular response.
The receptor-ligand union causes the production of second messengers that will activate effector proteins. Occurs an amplification of the signal.
- DIRECT ⇒ Occurs directly in the membrane.
<u>Ionic channel proteins</u> are activated and can change the chemical signal into an electric signal through ion flow.
When the molecule binds receptors that are associated with enzymes -or acting as enzymes- or to G proteins, it occurs a conformational change in the receptor cytoplasmic domain.
This change triggers an intracellular signal cascade in which many molecules participate and several<u> chemical changes</u> occur.
According to this framework, all the options are correct,
- The receptor can open an ion channel in the cell membrane.
- The receptor can act as an enzyme causing chemical changes in the cytoplasm.
- The receptor can cause the formation of a second messenger.
So te correct option is Option D. All of the above.
