Answer:
Carboxylhaemoglobin.
Explanation:
It has more affinity than oxylhaemoglobin. You see carbon monoxide bonds with haemoglobin to form carboxylhaemoglobin which is lethal that is can cause death.
Two separate species of squirrels have evolved after being separated by the Colorado River's erosion of the Grand Canyon. What type of speciation has occurred here?
A. Allopatric Speciation
B. Sympatic Speciation
C. Disruptive Selection
D. Group Behavior
Answer:
Option A
Explanation:
In this case the two species of squirrels have evolved when their combined population got divided into parts and was separated as a cause of natural calamity i.e Colorado River's erosion of the Grand Canyon, thereby forced to live in two different geographies and hence evolve differently from each other. The two geographies mentioned above remain disconnected by any natural barrier thereby restricting successful mating of the two population groups of squirrels.
hence, option A is correct
Answer:
Allopatric Speciation is Correct for all future users.
Explanation:
Why is bacteria and archaea not in the same kingdom
Which of the following provides the best evidence that the circulatory system and the respiratory system work together to carry out their functions?
A : Nutrients are absorbed into the blood from the intestines.
B : Lungs expand and contract through movements of the diaphragm.
C : New red blood cells are generated in the marrow of bones.
D : Gases exchanged in the lungs are carried by the blood.
Answer:
D
Explanation:
Your first order of business should always be to see which answers involve both of the systems. A has the circulatory system (blood) but no respiratory system (intestines are the gastrointestinal system), B has the respiratory system (the lungs) but no circulatory system, C has the circulatory system (new red blood cells) but not the respiratory system (bones are the skeleton), and that just leaves D, so it has to be the answer. When you look at it to check, it includes both systems, as the lungs are part of the respiratory system and the blood is part of the circulatory system.

what process occurs in the cytoplasm at the ribosome in the process of protein synthesis
Answer:
translation
Explanation:
The molecule of mRNA then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs. During translation, the genetic code in mRNA is read and used to make a protein. These two processes are summed up by the central dogma of molecular biology: DNA → RNA → Protein.

You will write a position paper (your Own opinion) expressing whether you are FOR or AGAINST the building of roads in Rainforests.
You might need to do a little research on Rainforests but if you already have knowledge on this topic then that's great. Find out why people have cut down trees and ruined the Rainforests and why they built roads in it. This is an Opinion paper, so there is no wrong answer if you pick either side but please still make the answer a good one. Just express your opinion on whether you are FOR or AGAINST the building of roads in the rainforest. It has to be 2 paragraphs of 4 sentences or more.
Please remember I WILL BE GIVING BRAINLIEST TO THE BEST CORRECT AND GOOD ANSWER!!!
Answer:
We live in an era of unprecedented road and highway expansion — an era in which many of the world’s last tropical wildernesses, from the Amazon to Borneo to the Congo Basin, have been penetrated by roads. This surge in road building is being driven not only by national plans for infrastructure expansion, but by industrial timber, oil, gas, and mineral projects in the tropics.
Few areas are unaffected. Brazil is currently building 7,500 kilometers of new paved highways that crisscross the Amazon basin. Three major new highways are cutting across the towering Andes mountains, providing a direct link for timber and agricultural exports from the Amazon to resource-hungry Pacific Rim nations, such as China. And in the Congo basin, a recent satellite study found a burgeoning network of more than 50,000 kilometers of new logging roads. These are but a small sample of the vast number of new tropical roads, which inevitably open up previously intact tropical forests to a host of extractive and economic activities.
Explanation:
Answer:
Deforestation on rainforests and other natural environments can have a devastating effect on the whole world. First, it leads to the loss of many animal and plant species, decreasing the biodiversity that our planet enjoys. It can also lead to the degradation of soil and to erosion, as trees and plants usually hold the ground in place and provide necessary nutrients to it. Deforestation also has a negative effect on climate change, as trees are able to absorbe an enormous amount of greenhouse gas emissions. Without them, the greenhouse effect is amplified, worsening climate change.

Why are marsupials only found in Australia?
Answer:
B. Australia is isolated
Explanation:
They originated in South America and spread throughout the world, but due to competition on other continents, the other marsupials died out, while the ones on Australia lived.

What is it about the structure of the alveolar-capillary unit that makes diffusion possible? Select all that apply.The capillaries are large. The cell wall of the alveoli is thin. Many capillaries surround one alveoli sac. There is always low pressure in the alveolar-capillary unit. The alveolar-capillary unit provides a large surface area.
Answer:
The most successful option would be: Many capillaries surround a sac.
Explanation:
Although in this question, I wanted to tell you that among all the options that is the most correct, but it is incomplete.
The capillaries that are in the alveolar unit are not only in great numbers to ensure gas diffusion but they are also SINUSOID capillaries where the cells of these capillaries do not have tight cell junctions, and there is a micrespace between cell and cell that forms the capillary wall.
And why is this? Because the greater the permeability of the capillary, the better the process of gas homeostasis or gas exchange at the alveolar level will be favored.
I hope I have completed your question, because it is very important that you know this, they are not simple capillaries that are only increased in number, but their sinusoidal permeable form makes them fulfill a VITAL function for the human being, this does not mean that all the capillaries of the body are like this, do not forget that we are speaking on time of the socket.
Answer:
B. The cell wall of the alveoli is thin
E. The alveolar-capillary unit provides a large surface area
Can you answer this science question for me please?

how is volume meausred
Answer: Volume is measured in cubic meters or cm
Explanation: In the International System of Units (SI), the standard unit of volume is the cubic meter (m3). The metric system also includes the liter (L) as a unit of volume, where one liter is the volume of a 10-centimeter cube. Thus 1 liter = (10 cm)3 = 1000 cubic centimeters = 0.001 cubic meters, so.
Answer:
Volume can be measured in many ways. It can be found in a cube by length*width*height. It can be found in a cylinder by doing pi*radius^2*height. For a sphere it can be found by using (4 × π × r^3)/3. It can be found in a cone by doing (π × r^2 × h)/3. In a pyramid you can use (B × h)/3.
Explanation:

The messages that scientists are sending into space are directed at intelligent alien life. Do
you think this is limiting? How could this affect scientists search for life beyond Earth?
Answer:
I think there is life beyond earth. Actually there most definently is. I think in a way it could be limiting. It's the fcat that the ones out there may not even be able to receive the message as fast as we please. Who knows, it could be years, decades, maybe centuries before they make actual contact with us. Then again, maybe they already have. But, the way this could affect the study is the fact that (I doubt it) but maybe a message could be sent the wrong way, or they misinterpret it. That's the only think I can get off. Anyway, this can also depend on how much funding is going into space. This also brings up the question, "How much do we know about our own planet?

Explanation:
why are there no gram-positive archaea species but there are gram-positive bacteria species
Answer:
There are no gram-positive archaea because archaea lack peptidoglycan in their cell walls, meaning that the archaic cell walls are more similar to gram-negative bacterial walls, although they do show a greater variety of cell wall types. And bacteria do have this.

What do you think happens to a fish’s behavior in cold climates during winter explain
Answer:
it changes just as the weather changes
Explanation:
so as it gets colder the fish get colder as well meaning that the fish will expect its habitat to turn warmer just as we humans (some of us aliens jkjk) want warmth when we are cold its the same thing with fishes
