The vascular cambium produces secondary phloem and xylem tissue.
<span>Vascular cambium, a plant tissue located between the xylem and the phloem in
the stem of a vascular plant. It is also the source of both secondary xylem growth
and the secondary phloem growth. Vascular
cambium is usually found on dicots and gymnosperms not on monocots which
usually lack secondary growth. It does not transport water, dissolved food or
minerals by plants. </span>
<span>Vascular cambia are cylinders of unspecialized meristem cells which
divide to make new cells which
specialize to form secondary vascular tissues.</span>
Answer:
Ovulation, ejaculation, implantation, fertillisation, development, birth
Explanation:
Answer:
The correct answer is option - D. phosphorylation.
Explanation:
The CARD11 or caspase recruitment domain-containing protein 11 is a gene that provides instructions for gene expressing to make a protein in the function of lymphocytes in the immune system. Lymphocytes like B and T cells are activated with the help of cascade reactions in which these genes provide information.
The protein that activates is PKC which is a kinase enzyme that implicates that the process that activates CARD11 is phosphorylation.
Thus, the correct answer is option - d - phosphorylation.
Answer:
1. Obtaining energy
2. responding to a stimulus
3. reproduction
4. excretion
Explanation:
1. All living organisms require energy for their life processes. This energy is derived from food. The food we eat contains biomolecules that store energy. The energy stored by these food molecules is released by a process called RESPIRATION. Image 1 shows a cat trying to obtain energy by feeding. The food will eventually be broken down to release energy.
2. Stimulus is any thing (whether internal or external) that causes a change in an organism. In image 2, a man is responding to a sudden change in his back, which is pain.
3. Reproduction is a characteristics of living organisms that involves the production of young ones. Image 3 depicts two cells undergoing fertilization (fusion of nuclei) to produce a new cell. In turn, the cell divides again to form two gametes. The cycle continues like that.
4. Excretion is the removal of waste products from a cell. According to Image 4, the cell allows a food particle in and releases the waste contents out of the cell.
the key element in the ecological concept of species is that individuals within a species can successfully interbreed and conceive healthy offspring
