What process takes place at the boundary between the capillaries and the alveoli?

Biology
1 answer:
Schach [20]2 years ago
5 0

Answer:

Carbon dioxide enters the alveoli, and oxygen enters the capillaries.

Explanation:

This describes the exchange of gases in the lungs. When blood from the rest of the body gets to the lungs through the capillaries, oxygen flows from the alveoli which are tiny air sacs in the lungs, into the blood in the capillaries.

Carbon dioxide from the blood brought to the lungs will then flow into the alveoli which will then expel it through the nose. This repeated process ensures that the body keeps getting oxygen and expelling carbon dioxide.

Which statement is false about fungi?
alekssr [168]

Answer:

C) Most fungi get their nutrients by ingesting small pieces of other living organisms.

Explanation:

Most fungi are saprotroph, it is, they obtain  nutrients by decomposing  non-living organic matter -i.e.  dead plant or animal matter-  and absorbing soluble organic compounds; carbohydrates are the preferred carbon source.

A smaller percentage of fungal species are parasites, and obtain nutrients from living hosts (other living organisms).

Distinguishing the Domains of Life
vitfil [10]

Answer:

1) Organisms in this domain can be unicellular or multicellular - Eukarya

2) Organisms in this domain are unicellular and are often found in extreme environments - Archaea

3) Organisms in this domain have cells that contain a nucleus - Eukarya

Explanation:

All living organisms were classified into a large group consisting of three types of organisms called DOMAIN. It is the highest taxonomic rank of organisms. The three domains that life was classified into are: Archaea, Bacteria and Eukarya.

The domain Archaea contains organisms that are unicellular and prokaryotic i.e. they do not have a membrane-bound nucleus. The organisms in this domain are characterized by their ability to survive in harsh environmental conditions e.g hot temperatures etc

The domain Bacteria also consists of unicellular and prokaryotic organisms. They contain cell walls in their cells made up of peptidoglycan unlike domain Archaea and Eukarya.

The domain Eukarya consists of organisms that are both unicellular and multicellular and strictly eukaryotic i.e. possess a membrane bound nucleus that houses their genetic material. They are divided into Kingdoms: Protista, Plantae, Animalia and Fungi.
