The question does not have the option which are:
depleted in red light; inactive form
enriched in red light; active form
depleted in red light; active form
enriched in red light; inactive form
depleted in red light; inactive form
Answer:
depleted in red light; inactive form
Explanation:
The understory is the lower portion of the forest canopy which is characterised by the shade-tolerant species of the plants.
The light that reaches the lower portion or in the understory is depleted in the red light wavelength.
The phytochromes are the photoreceptor or blue-green pigment which response to the red and far-red wavelength. The low light converts the phytochrome to its inactive form Pr form which is reversible.
Thus, the selected option is correct.

<h2>Functions of spleen</h2>
Explanation:
The major functions of spleen besides filtering the blood of foreign materials and phagocytosis of old defective erythrocytes are:
- Initiate immune responses against infections by liberation of antigen and activation of lymphocytes (T and B cells)
- Secretes bactericidal agents which act against invading bacteria
- Secretes interleukins which promote the growth of lymphocytes or antibodies that act against pathogens
- Reservoir: Pools blood by storing thrombocytes, immature erythrocytes.
- Hematopoiesis: Blood cells like erythrocytes, lymphocytes and monocytes develop and mature in spleen especially during the early fetal life.
Answer:
complementary DNA (cDNA)
Explanation:
The complementary DNA (cDNA) is a region of DNA that is synthesized from an RNA template by using a reverse transcriptase enzyme. cDNA is usually used to clone genes from eukaryotic organisms in prokaryotes. cDNA cloning is a technique that consists of isolating and amplifying a self-replicating prokaryotic organism that includes in its genome a cDNA of interest. This technique enables the insertion of fragments of eukaryotic DNA (cDNA) into plasmids that subsequently are multiplied by cloning and finally sequenced.
Answer:
A. a protein
Explanation:
Proteins function as enzymes in most of the catalyzing reactions, that increases the rate of reaction within cell.
Proteins are consist of multiple numbers of amino acids and the twisting and folding amino acids provide a unique identity to enzymes. Not all the proteins are enzymes but all the enzymes are proteins.
For example: Trypsin, Pepsin, and Lipases.
Hence, the correct option is "A. a protein".
