Answer:

C (Photosystems)

Explanation:

Photosynthesis occurs in two distinct stages, the Light-dependent stage and light-independent stage. The light dependent stage generally involves capturing the light energy from sun to produce ATP and NADPH. It occurs in the thylakoid membrane of the CHLOROPLAST.

The light-dependent reaction cannot occur without a large complex of protein and pigment molecules (light-absorbing) called PHOTOSYSTEMS. The photosystems are structured to harvest photons of light, which triggers electron donation by Chlorophyll, photolysis of water and subsequently creation of proton pump to yield ATP and reduction of NADP+ to NADPH. Photosystems consist of Photosystem I (P680) and II (P700).

You have learned that having linear DNA has consequences, the major one being that the DNA is shortened every time it replicates
dimaraw [331]

Answer:

The sites of replication.

Explanation:

Linear DNA is and advantage for bigger organisms because there can be many places where replication can occur, otherwise, in circular DNA replication can only happen in he ORI place, that is unique. This feature allows to replicate several genes in the same amount of time being more efficient in protein synthesis.

What are the two categories of behavior? Provide an example of each.
olga nikolaevna [1]

Answer:

Explanation:

The two categories of the behavior includes the operant behavior and respondent behavior.

Operant behavior: The operant behavior can be define as the behavior that is under the control of the consequences. These consequences are likely to control the future frequency of behavior. For example, A child who is allowed to hit other children and take their toy, is likely to be aggressive to other people in the future.  

Respondent Behavior: The behavior which is under the influence of a specific stimuli is a respondent behavior. For example, Snapping of hand away from a hot pan, and Salivation of the mouth due to food.

If adenine didn’t always pair with thymine and guanine didn’t always pair with cytosine, the new DNA ladders wouldn’t always be
zloy xaker [14]

Answer:

they wouldnt be identical because for example Guanine could be paired with thymine in the original DNA strand but could decide to pair with adenine in the replication DNA. that would make a different type of DNA.

Explanation:

DNA replication is a beautiful process. In DNA replication adenine only pairs with thymine and guanine only pairs with cytosine. this ensures that a replication of the DNA will be the same type of DNA.

Replication works like this. Helicase splits open the DNA and each side is copied by DNA polymerase. If let's say the nucleotide bases for side 1 are ATGCGA then the DNA polymerase will pair these with the matching bases TACGCT which will make the same DNA but if each base could pair with any base they want that could create a few different variations of the original DNA. ATGCGA could very well be paired with TCGACA or CGACTA which would created two different types of DNA.
