What process occurs at the boundary between the capillaries and the alveoli?


A.
Nitrogen enters the alveoli, and oxygen enters the capillaries.
B.
Oxygen enters the alveoli, and carbon dioxide enters the capillaries.
C.
Oxygen enters the alveoli, and nitrogen enters the capillaries.
D.
Carbon dioxide enters the alveoli, and oxygen enters the capillaries.

Answers

Answer 1

Answer: D.  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.

Those parts of the surrounding states of Montana, Idaho, and Wyoming that are closest to Yellowstone would be affected by pyroclastic flows, while other places in the United States would be impacted by falling ash (the amount of ash would decrease with distance from the eruption site).

An athlete throws the javelin 212 m. The average speed of the javelin was 15 m/s. How long was the javelin in the air?

Answers

Answer:

The correct answer is - 14.133 seconds.

Explanation:

The time that the javelin took in the air before landing after the 212 m throw can be calculated by simple distance and velocity formulas which say that the speed of an object is equal to the distance traveled by the object in unit time.

Given:

Speed or s = 15 m/s

Distance or d = 212 m

Then, the time or t =?

Solution:

By the formula, s = d/t

or t = d/s

t = 212/15

t = 14.1333

thus, the correct answer is - javelin was in the air for 14.1333 seconds.

2) Genus Alienus

3) Morphological characteristics of aliens are used to identify them and to name them.

Explanation:

1) The dichotomous keys give you information about the groups that are being differentiated to correctly identify them. All you need to do is follow the description of the organisms and the numbers where each description drives you. If you observed correctly the organism, you will reach the scientific name, or genus, or any other taxonomic group you are looking for.

2) Taxonomy is the study of different organisms, their classification into categories according to their morphological and molecular characteristics and their evolutionary relationships. A binomial name is assigned to each organism, composed of a genus and the epithet.  

Among all the categories where organisms are classified, we can find the genus, which includes many species that share some common characteristics that are used to group them together.  

In this example, Alienus is the genus of all these aliens species.

3) Morphological characteristics of aliens are used to identify them and to name them.

Alienus quadlegicus:  Four-legged alienAlienus hairicus: Hairy alien.Alienus tritoothicus: Alien with three teethAlienus stripicus: Alien with striped hornsAlienus bloblicus:  Alien with no shape. Shapeless massAlienus fuzzicus: Short fine-haired alien.
