Answer:
Photosynthesis converts light energy to chemical energy in plants and cellular respiration converts biochemical energy from nutrients in organisms.
Explanation:
- Photosynthesis is a process that occurs in green plant that synthesizes food for plants from the use of sunlight and series of chemical reactions.
- Similarly cellular respiration also does the same but it uses nutrients consumed from the body to produce energy for different cellular activities.
- Cellular respiration converts energy into ATP form in organisms.
- Photosynthesis uses sunlight where as cellular respiration needs oxygen to prepare food and energy.
The answer to this question is B
Answer:
b. false
Explanation:
The cell cycle consists of three states: Interphase, Cell division (mitosis) and Resting.
Interphase is composed of phases G1, S and G2. during this state the cell replicates the genetic material of its chromosomes to prepare itself for cell division
In G1 the cell synthesizes mRNA and proteins that the cell will need during mitosis.
In S the cell replicates the genetic material of its chromosomes to prepare itself for cell division. At the end of this phase each chromosome is composed of two sister chromatides.
In G2 the cell grows and and more proteins synthesized for mitosis.
Mitosis is the production of two daughter cells from a sinlge one. During the entire mitosis the chromosomes are duplicated in the cell until finally, the genetic material is distributed in two cells after cytokinesis.
According to the above, it can be seen that the chromosomes in a cell that is in the cell cycle do not necessarily have sister chromatids. For example, chromosomes during G1 do not have sister chromatids.
Answer:
Dichotomous keys typically stress identifying species by their scientific name, as each individual species has a unique scientific name. Dichotomous are very useful because they allow non-expert users to identify organisms by directing them to look at the known, important organisms.
