the protein that carries oxygen in our blood is known as

Answers

The protein that carries oxygen in our blood is known as hemoglobin.

Iron is a component of hemoglobin, which enables it to absorb oxygen from the air we breathe and transport it throughout the body.

What is Hemoglobin?

The iron-containing oxygen-transporting metalloprotein known as hemoglobin, often known by the abbreviations Hb or Hgb, is found in the red blood cells of almost all vertebrates as well as some invertebrate organs. The oxygen from the respiratory organs is transported to the rest of the body by hemoglobin in the blood.

The normal ranges for haemoglobin are different for males and females, and they also vary depending on the ethnicity of the population. Additionally, age is a factor, particularly for women.

When you have anemia, your body doesn't produce enough healthy red blood cells to supply your tissues with enough oxygen. Anemia, commonly known as low hemoglobin, can make you feel exhausted and frail.

Do you have a positive, negative, or zero change in population? How many members are in the new population?

Answer should contain the following information: work for calculating the change in population positive, negative, or zero change in population. Work for calculating the new population.

Answers

Answer:

0 change in population. I think.

Explanation:

first we are adding 32 ants to the total because 32 ants were born so 1000+32 = 1032.

Next we are subtracting 32 ants from the new total because a pesticinde was used in the area. So 1032 - 32 is 1000. 1000 was the original total so there was not a decrease in popualtion or an increase.

why are there earthquakes​

Answers

Answer:

Earthquakes are usually caused when underground rock suddenly breaks and there is rapid motion along a fault. This sudden release of energy causes the seismic waves that make the ground shake. The earthquake starts at the focus, with slip continuing along the fault. The earthquake is over when the fault stops moving.

The fish shown here is normally found in a pond but is being studied in an aquarium. The amount of water and salt intake and excretion is measured as the fish maintains homeostasis. What scientific
question is most likely being asked based on the information in the model?

Answers

Based on the information in the question, we can infer that the question being asked is most likely "What mechanisms do fish use to maintain homeostasis in salt-water environments?".

What is homeostasis?Homeostasis is a series of regulatory processes by which an organism maintains core values (or range of values) necessary for everyday life.

How to test the questionThe question is in the form of a hypothesis.This means that the scientist must first propose a possible solution to the question.Then, the scientist will make observations based on this question. In this case, it would seem the scientist has placed the fish into an environment that differs from its natural habitat, in order to observe how the fish maintains homeostasis.

Therefore, we can infer that the most likely question being asked is in regards to the way in which fish maintain homeostasis.

Question 2:
In 1–2 sentences, explain what biome comprises most of Antarctica and why the continent is described as being part of this biome.

Answers

Answer:

question 1

Low-pressure areas are places where the atmosphere is relatively thin. Winds blow inward toward these areas. This causes air to rise, producing clouds and condensation. Low-pressure areas tend to be well-organized storms

question 2

Scientists that work in Antarctica mostly refer to the majority of the continent as being cold desert or polar desert. The difference between cold and polar desert is very technical, mainly dealing with mineral salt chemistry.
