Human blood has a pH of 7.4. How do buffers in the blood affect the pH?

Biology
1 answer:
ikadub [295]3 years ago
6 0

Answer:

C

I think buffers prevents small amounts of acids and blood from coming and changing the pH of the body, because the buffers are barriers that do not let blood and acid pass through.

Hope it helps!

How do trees act as carbon sinks?
Romashka [77]


The best answer is D.

A carbon sink is anything that absorbs more carbon than it produces or releases.

The main carbon sinks found in nature are plants, the ocean and soil.  Plants such as trees capture carbon dioxide from the atmosphere and use it in photosynthesis. Part of this carbon is transferred to soil as the trees and other plants die and decompose.

Due to the effectiveness of trees and other plants as carbon sinks,  the Kyoto protocol proposed that emission reduction can be achieved through absorption of carbon dioxide by these plants.

Which of the following organelles is the principal and distinquishing feature of the eukaryotic cell? A. ribosomes B. chloroplas
dsp73

Answer:

E. Nucleus

Explanation:

All living organisms were classified into three major domains viz: Eukarya, Archaea and Bacteria. Eukarya are referred to as EUKARYOTES while the other two domains are collectively referred to as PROKARYOTES.

The major basis of this classification is the presence or absence of a membrane bound NUCLEUS. Eukaryotes are organisms characterized by the possession of a membrane-bound nucleus that houses their genetic material (DNA) while prokaryotes lack a nucleus and hence, their genetic material is found naked in the cytoplasm. Although, prokaryotic cells lack other membrane-bound organnelles like Chloroplast, mitochondria etc. but nucleus is the basis of this classification:

EU meaning TRUE, KARYA meaning NUCLEUS, hence Eukarya means organisms will true nucleus.

Which of the following is NOT a process that drives the carbon cycle?
stiks02 [169]

"Ammonification" is NOT a process that drives the carbon cycle.

<u>Option: B</u>

<u>Explanation:</u>

The organisms circulate carbon-di-oxide in carbon cycle by going through respiration, decomposition, sedimentation, and photosynthesis process but not ammonification. Basically the actual source of nitrogen is agricultural, when a plant or animal passes or an animal disperses waste.

In the remains, bacteria or fungi turn the organic nitrogen back into ammonium, a cycle called ammonisation or mineralisation. Then the micro-organisms generate metabolically required energy from organic nitrogen oxidation into ammonium. Ammonium is then essential for assimilation and absorption into amino acids or for use in other metabolic applications.
