Why is bacteria and archaea not in the same kingdom
What are examples of two
species dividing up the parts of a habitat?
•
helpppp plzzzz
Answer:
In a hot spring in Kamchatka, Russia, the two groups of genetically indistinguishable microbes parted ways. They began evolving into different species—despite the fact that they still encountered one another in their acidic, boiling habitat and even exchanged some genes from time to time, researchers report.
Hope this helps

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
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
Which action causes the movement of atmospheric heat from place to place in the troposphere?
Cold air is denser than warm air; it will sink below warmer air, pushing warm air upward.
Earth’s rotational movement pushes air from northern areas to southern areas.
Heat moves from a cooler object or place to a warmer object or place.
Gases in the atmosphere block solar energy, so the sun’s heat does not reach the troposphere.
Answer:
Cold air is denser than warm air, it will sink below warmer air, pushing warm air upward.

Explanation:
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.
How is population growth likely to affect the supply of wind energy and its environmental effects?
Answer:
Population is growing rapidly, far outpacing the ability of our planet to support it, given current practices. Overpopulation is associated with negative environmental and economic outcomes ranging from the impacts of over-farming, deforestation, and water pollution to eutrophication and global warming.

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.
Can you answer this science question for me please?
Answer:
Well if we look at Darwin's theory, living things adapt over time. Such as our appendix, it is there but it isn't used. Same thing with wisdom teeth, they aren't used or required.
Hopefully this answers your question!

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.
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.
process of fertilized eggs
Answer:
Explanation:
Fertilization occurs when the nucleus of both a sperm and an egg fuse to form a diploid cell, known as zygote. The successful fusion of gametes forms a new organism.
What would the Earth look like without radiation from the sun? *
Answer:
Without the Sun's heat and light, the Earth would be a lifeless ball of ice-coated rock. The Sun warms our seas, stirs our atmosphere, generates our weather patterns, and gives energy to the growing green plants that provide the food and oxygen for life on Earth.

O Fish can live in rivers and streams, whereas plants grow in lakes and ponds.
O Lakes and ponds form only after heavy rains, whereas rivers and streams always exist.
Second one.
"Unlike the water in lakes and ponds, the water in rivers and streams flows."
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.
