Answer:
if ur asking which one of those answer choices is the right one, it's D! Deliver oxygen to every blood cell <3
Explanation:
This involves transport of oxygen from the lung to the tissues by means of the circulation of blood.
Answer:
When water is added to a graduated cylinder, having a surface where the sides of the water look higher than the center means that the curved surface is a concave meniscus which has formed because of surface tension (Choice C).
Explanation:
A meniscus is simply the curvature that the surface of a liquid acquires when it is in a container, such as a graduated cylinder. It is concave when there is attraction between molecules -water and glass- or it can be convex when both surfaces are repelled.
<u>Water is a polar molecule</u>, with the capacity to adhere to the surfaces it comes into contact with. This characteristic causes it to form a concave meniscus, as the outermost molecules adhere to the glass surface, while the surface tension of the water attracts the molecules from the centre downwards, causing the concavity.

To test for the keystone species hypothesis, the wolves in another region can be removed or trees can be reintroduced to see the effect on the ecosystem.
<h3>What is a keystone species?</h3>
A keystone species is an organism whose existence defines an entire ecosystem such that them, the ecosystem would be severely affected or may not exist.
Trophic cascades are events which result in serious distortions in an ecosystem as a result of the removal or addition of a top predator.
To test for the hypothesis of keystone species and trophic cascades, the wolves in another region can be removed or trees can be reintroduced to see the effect on the ecosystem.

Answer:
this tree tells us that the amnion is found in mammals, lizards, snakes, crocodiles, and birds
Explanation:
<u>Answer</u>:
From only two seismic stations data we can get the direction from which the Earthquake originated.
<u>Explanation</u>:
When the information taken into consideration from only one station, it tells us about the epicenter of the earthquake could at any point on that circle. when the information comes from two stations, the circles intersect at 2 points, so there are possibility of having two epicenters. With three stations, the circles intercept at only one point, which must be the epicenter. The sesmic station present in the network helps in measuring the movement of plates from the ground motion. the signature sesmograph tells us about the bigger earthquakes.
