2. Adenine and guanine are

Biology
1 answer:
Anettt [7]3 years ago
8 0

Answer:

single-ringed purines

Explanation:

Adenine and guanine are purine bases. They are structures composed of a 5-sided and 6-sided ring. Cytosine and thymine are pyrimidines which are structures composed of a single 6-sided ring. Adenine binds to thymine, while cytosine binds to guanine. This relationship is a form of complementary base pairing. These complementary bases are bonded together by hydrogen bonds.

2. What do you notice about the cellular respiration and<br> photosynthesis equations?
ryzh [129]

Answer:

Photosynthesis and cellular respiration are connected through an important relationship. ... Notice that the equation for cellular respiration is the direct opposite of photosynthesis: Cellular Respiration: C6H12O6 + 6O2 → 6CO2 + 6H2O. Photosynthesis: 6CO2 + 6H2O → C6H12O6+ 6O

27. What is the reaction for aerobic cellular respiration?
Semmy [17]

Answer:

Aerobic respiration is the aerobic catabolism of nutrients to carbon dioxide, water, and energy, and involves an electron transport system in which molecular oxygen is the final electron acceptor. The overall reaction is: C6H12O6 + 6O2 yields 6CO2 + 6H2O + energy

Hope this helps.

An anthropologist discovers the fossilized heart of an extinct animal. The evidence indicates that the organism's heart was larg
Paladinen [302]

A reasonable conclusion supported by these observations is that the animal was endothermic and had a high metabolic rate.

<u>Explanation:</u>

With reference to warm-blooded species is preferred the endothermic are the species that preserve a steady body temperature regardless of the ambient temperature. Endothermic species mainly include animal kingdom birds and mammals. Many shrimp, however are endothermic too.

If a variation occurs, i.e. if the heat produced is less than the heat loss, the metabolic rate increases to compensate for that loss. Shivering is another method used by people and many other warm-blooded organisms to boost their body temperature. But in case the heat loss is smaller than the heat produced, the process of panting or suddening occurs to increase the heat loss.

In response to seasonal changes in temperature, many organisms must alter the composition of their plasma membranes to maintain
katrin [286]

Answer:

The correct answer is D

Explanation:

The cell membrane is essentially composed of the following:

  • phospholipids
  • cholesterol
  • proteins

The phospholipid consists of a <em>hydrophilic </em>phosphate 'head' and the tail is the <em>hydrophobic</em> fatty acid chain.When cellular membranes form,phospholipids collect into two layers in light of these hydrophilic and hydrophobic properties. The phosphate heads in each layer face the fluid or watery condition on either side, and the tails conceal away from the water between the layers of heads, since they are hydrophobic.

There are 3 main factors that greatly influence the fluidity of the plasma membrane:

  • temperature
  • cholesterol
  • saturated and unsaturated fatty acids
