The actively dividing cells, or meristems, control plant growth. Primary (apical) meristems, the dividing tissue at the tips of the roots, grow longer roots, and secondary meristems, the dividing tissue seen in the cross-sections, grow thicker roots.
Answer:
Because it might it might not want to
Answer: 1. a. logistics model of growth
2. a. environmental conditions
3. b. all limiting factors
4. b. water availability
Explanation:
1. a. logistic model of growth will show the increase in population of a species in accordance with the carrying capacity exponentially but when the population will experience the scarcity of resources it will decline considerably.
Carrying capacity is the total number of members of the population of a species that an ecosystem can sustain by providing resources.
2. b. All environmental conditions which favor the survival of the living beings will contribute to the carrying capacity for example food, water, shelter, and other resources.
3. b. Limiting factor is the one which limit the chances of survival and growth of a particular species in an ecosystem. For example, scarcity of food, here food is the limiting factor.
4. d. A density dependent limiting factor is the one which affects the population of the species based upon the density. The water availability is a density dependent limiting factor because the more the density or abundance of a population more will be the scarcity of water as it will be required by all organisms. So, the species population may experience decline due scarcity of water.
Answer:
do not bind the small ribosomal subunit.
Explanation:
5' CAP is a structure present only in the mRNA molecule. It is characterized as a "helmet" added to the 5' end of the mRNA molecule.
The main function of 5' CAP is to protect mRNA in the cytoplasm (when it leaves the nucleus towards the ribosome). This is because in the cytoplasm can be found the enzymes ribonucleases and fostases that can alter the function of proteins that allow the mRNA to bind to the smaller subunit of the ribosome.
Since tRNA and rRNA do not need to be linked to the ribosome, they do not need the presence of 5' CAP in their compositions.
Answer:
A
Explanation:
Gram positive bacteria stain violet due to the presence of a thick layer of peptidoglycan in their cell walls, which retains the crystal violet these cells are stained with.
