Biology
1 answer:
polet [3.4K]3 years ago
8 0

Answer:

6 thymine, 4 guanine. 4 cytosine

Explanation:

Adenine pairs with thymine, so you need 6 of each

Cytosine matches with guanine, but the total of nucleotides is 20, so

6(adenine)+6(thymine)=12

20-12=8

8= 4(guanine)+4(cytosine)

Chemical digestion of protein begins in the mouth with enzymes found in the saliva. T/F
Leona [35]

The answer would be:

F - False.

The chemical digestion of proteins actually starts in the stomach. Proteins are first digested by the enzyme pepsin, which is secreted by the stomach, along with hydrochloric acid (HCL). It is then digested further in the small intestine, specifically in the duodenum, with the help of the pancreas. The pancreas releases the enzymes chymotrypsin and trypsin.

They showed that adult cells could be reprogrammed to become cells with the properties of an embryonic stem cells
amid [387]

Answer: Kathrin Plath and William Lowry

Explanation:

Kathrin Plath and William Lowry and researchers at the University of California in Los Angeles(UCLA) were able to reprogram adult cells to become develop properties of embryonic stem cells which are very important as they can become any type of cell in the body which can have very important implications in medicine.

They did this by genetically altering the cells to enable them age backwards to a point where they were like the aforementioned stem cells.

When will chloroplasts be aligned with their flat surfaces parallel to the walls in mesophyll cells? When will they be perpendic
padilas [110]

Answer:

Flat surface parallel to mesophyll walls  position

Chloroplast assumed this position  in condition <u>of low  light intensities or optimum light intensities</u>   for the reception of maximum amount of incident light. necessary for photosynthesis

Perpendicular to the incident light position.

During condition of <u>extreme high light intensit</u>ies chloroplast  aligned in this position to avoid the loss of electrons from the chlorophyll from absorption of photons; (PHOTOXODATION.)  

Basically photooxdation is a wasteful process which destroys the plants.
