A or "The blood would not be able to carry oxygen."
Explanation:
"Red cells contain a special protein called hemoglobin, which helps carry oxygen from the lungs to the rest of the body and then returns carbon dioxide from the body to the lungs so it can be exhaled. Blood appears red because of the large number of red blood cells, which get their color from the hemoglobin."

Luisa went into the bathroom after her sister had a bath. It was full of mist and the mirror was covered with the a lot of liquid drops. What was the mist made of?
Answers
Answer:
Mist is made of water vapor.
Explanation:
The bathroom mirror and the fog that the bathroom presents after someone takes a shower, is formed by water vapor. This water vapor is formed by the hot water from showers, which evaporates. This water vapor is what forms the mist, however, when this mist touches the surfaces of the bathroom, such as the mirror, it becomes water again and that smothers the mirror. The mist becomes water when touching the mirror because of the difference in temperature between them, as the mist is hot and the mirror is cold. This happens through the condensation of water.

extinction, in which ecosystems change drastically
Explanation:
The emergence, growth, and extinction of a large clade, such as the dinosaurs, is an example of larger macroevolutionary patterns. This larger macroevolutionary patterns occur due to climate change. Extinction of organisms in which ecosystems change drastically that leads to unfavourable environmental conditions which decreases the population to the extinction of organisms.
Highlight all the atoms of the four functional groups, but do not highlight any bonds. When you click on each atom, it will change color. To deselect an atom, click on it again. Before you submit, check that you have not selected any bonds.
Answers
Hi. You did not submit any image, table or description of a molecule for the functional groups to be pointed out. This makes it impossible for your question to be answered. However, I will try to help you as best I can.
A functional group is a set of atoms of different chemical elements that take the place of a hydrogen atom that was part of a hydrocarbon (it is a molecule composed of carbon and hydrogen atoms). The most common functional group is −OH, but you also often encounter −SH, −NH2, and −OPO2−3 functional groups.

how is classification of animal related to its adaptational features
Answers
Answer:
it is important because it helps us identify and name all the animals on earth
Answer:
We can classify organisms on the basis of its physical features.
Explanation:
Classification of animal is related to its adaptational features because adaptational features of an organism provides information about the organism to which specific kingdom or phylum the organism belongs. These adaptational features are gained by the organisms due to different environmental as well as climatic conditions the organism have which make changes in the body features of an organism. So we can classify organisms on the basis of its physical features.

Answers
Answer:
are hydrophilic and face outward toward the aqueous solution on both sides of the membrane
Explanation:
The plasma membrane is structurally made up of a phospholipid bilayer, which is amphipathic in natire. This means that the phospholipid layer of the plasma membrane consists of phosphate head that is water loving or hydrophilic in nature and a lipid tail that is water fearing or hydrophobic in nature.
Since the phosphate head is HYDROPHILIC, they face outward toward the aqueous (water) solution on both sides of the membrane. This allows the phosphate head to attract water molecules.

This article is about carbon and how it moves around our planet. Carbon is the fourth most abundant element in the universe and the basic building block for all life. Carbon atoms are everywhere – the stone we walk on, the CO2 our bodies produce and release into the air, the backbone of polymers, and most importantly, carbon is the foundation of all life.
The total amount of carbon on the earth is essentially constant. Imagine a log of wood inside of a large sealed metal box filled with air. Weigh the entire box and its contents. Now cut the log up until it is just a pile of sawdust. Weigh the box again – it has the same weight. Now burn the sawdust inside until all that is left is a pile of ash inside a smoke filled box. Weigh the box again. The weight is the same as before.
