Explanation:
plants take in co2-->plant gets eaten-->animal dies, co2 moves to soil, some become fossil fuels
breathing puts co2 in the atmosphere, when fossil fuels are burned they are put into the atmosphere
co2 from the atmosphere dissolves in the surface of the ocean, photosynthesis

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.
Skin color, fur color, and height are examples of which inheritance pattern?
A. Mendelian inheritance
B. incomplete dominance
C. codominance
D. polygenic inheritance
Answer:
D
Explanation:
Skin color, fur color, and height are examples of polygenic inheritance. Thus option D is correct.
What is polygenic inheritance?Polygenic inheritance is defined as a type of heredity where the trait is created by the interactions of many genes, as opposed to monogenic inheritance where the phenotype is created by the expression of just one gene.
When numerous separate genes have an additive or comparable effect on a single quantitative characteristic, this is known as polygenic inheritance.
Multiple gene or multiple factor inheritance are other names for polygenic inheritance.
The some of the characteristics are since epistasis is not at play, the expression of one gene is not obscured by the existence of the other genes. There are no dominant or veiled genes; the gene involved in polygenic inheritance is either contributing or non-contributing.
Thus, skin color, fur color, and height are examples of polygenic inheritance. Thus option D is correct.

What is the purpose of a gene
Answer:
Genes are a set of instructions that determine what the organism is like, its appearance, how it survives, and how it behaves in its environment. Genes are made of a substance called deoxyribonucleic acid, or DNA. They give instructions for a living being to make molecules called proteins.
Explanation:
Genes tell your body how to make all its proteins. Each new cell in the growing embryo receives a full set of genes. But not every cell needs to make every protein and cells make some proteins only at certain times. Some genes are instructions for proteins that regulate the activity of other genes.

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.

4- Las plantas que viven en sitios húmedos y con poco sol tienen raíces poco profundas. Las que viven en sitios de mucho calor tienen raíces muy profundas. ¿Por qué?
Esto es debido a que en los lugares húmedos las plantas absorven el agua con las hojas y no necesitan hacer crecer la raíz para buscar agua. En cambio, las plantas que viven en lugares calurosos necesitan agua por lo que expanden las raíces hacia abajo para poder encontrar líquido e hidratarse.
Which of the following symbiotic relationships is considered parasitic?
A. Tapeworm in an intestinal tract
B. Bees transporting pollen from flowers
C. Pilot fish swimming under sharks
D. Birds eating the insects from the back of a hippopotamus
Answer:
A. Tapeworm in an intestinal tract.
Explanation:
This symbiotic relationship is parasitic because the tapeworm causes harm to the host. Tapeworms feed off the nutrients the host consumes, thus making the host sick.
Not parasitic:
Bees transport pollen from flowers back to the nest to feed the young bees, but pollinate female flowers as well which keeps the flower population alive.
Pilot fish swim under sharks to keep other prey from eating them, and the shark do not eat eat the pilot fish.
Birds eating the insect of the back of a hippopotamus keep the hippo clean and parasite-free as well as feeding the birds.
The presence of tapeworm in intestinal tract is considered parasitic. Thus, the correct option is A.
Symbiotic relationships refers to the association between two two organisms belonging to different species. There are three types of symbiotic relationships which are mutualism, commensalism and parasitism.
In mutualism, both of the organisms involved are benefited from the relation.
In commensalism, one of the organisms involved is benefited and the other is neither benefited nor harmed from the association.
In parasitism, one of the organisms involved is benefitted and the other one is harmed from the association.
As in the relationship between tapeworm and human, tapeworm is benefited but the human involved is harmed. Thus, it is a parasitic relation.
Thus, the correct option is A.

what forces cause surface ocean circulation? what forces cause deep water circulation?
Answer:
ANS 1) Ocean currents can be caused by wind, density differences in water masses caused by temperature and salinity variations, gravity, and events such as earthquakes or storms. Currents are cohesive streams of seawater that circulate through the ocean.
ANS 2)n the deep ocean, the predominant driving force is differences in density, caused by salinity and temperature variations (increasing salinity and lowering the temperature of a fluid both increase its density). There is often confusion over the components of the circulation that are wind and density driven.

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?

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.

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.

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.
