Complete the sentence. Carbon flows between ____________, environmental storage centers that absorb and store carbon for long periods of time.
plants and animals
humans and air
rocks and soil
carbon sinks
Carbon is transfered by plants and animals.
Carbon flows between plants and animals, environmental storage centers that absorb and store carbon for long periods of time. Thus, the correct option is A.
What is Carbon cycle?Carbon cycle is one of the main biogeochemical cycles which has four main steps. In this first, carbon enters into the atmosphere as CO₂. CO₂ is absorbed by the autotrophs such as green plants for photosynthesis. Then, the animals consume plants as food, thereby, incorporating the carbon into their system. Afterwards, animals and plants die, their bodies decompose and the carbon is reabsorbed back into the atmosphere.
In this, plants use carbon dioxide for photosynthesis. Through this, they remove the inorganic carbon from the atmosphere and incorporate it into the plant's tissues in the form of sugars such as glucose, sucrose and starch. Animals get carbon by eating the plants or by hunting other animals.
Therefore, the correct option is A.

Individuals with thicker fur had a survival advantage in the cold
Explanation:
Natural selection means the process of changing the adapting the new environment. Based on the given data one can conclude that the individual with thicker fur had a survival advantage in the cold environment.
Why natural selection occurs?Natural selection takes place due to 3 underlying reasons:
ReproductionHeredityVariation in fitness of organisms.Due to these reasons, natural selection can leads to speciation.
As the individual are living in cold environment, they need to adapt the change in environment. So, individuals with thicker fur had a survival advantage in the cold environment, allowing these individuals to reproduce more often and create more offsprings.

Explanation:
I'm guessing the answer is oxygen.
The oxygen cells are a type of cell that uses chemicals to recycle elements in the blood.
What is oxygen cells?Red blood cells, also known as erythrocytes, transport oxygen to your body's tissues. Your tissues emit carbon dioxide as oxygen is converted into energy. Red blood cells also transport carbon dioxide to your lungs for exhalation. Cells require oxygen to efficiently use glucose in cellular respiration. This is how most organisms obtain energy. When oxygen binds to parts of glucose molecules, water, carbon dioxide, and energy are released. After all, the organism uses the energy to create adenosine triphosphate (ATP).

Answer:: De-termination could offer experiences into development and normal assets that are at present inaccessible to us.
2: Compromised or harmed biological systems could be reestablished with the assistance of specific now-wiped out species.
3 In the event that people drove plant and creatures species into termination, maybe we owe it to these species to attempt to bring them back.
4 De-elimination could be a major advance forward for hereditary designing.
There are loads of valid justifications to bring back wiped out creatures. All creatures perform significant jobs in the environments they live in, so when lost species are returned, so too are the 'positions' they once performed. Wooly mammoths, for instance, were nursery workers. ... It very well may be something similar for other de-wiped out creatures, as well.
Zeroing in on de-elimination could think twice about by redirecting assets from protecting environments and forestalling more current eradications. It could likewise diminish the ethical load of annihilation and backing for imperiled species, sending the mixed signal that resuscitating a wiped out creature or plant is trifling

a. Viruses reproduce using a ______ _____.
b. What are the differences between proviruses and viral DNA?
c. Why is the common cold virus so difficult to cure?
Answer:
Viruses reproduce using a host cell
The differentce between proviruses and viral DNA is A provirus is a virus genome that is integrated into the DNA of a host cell. In the case of bacterial viruses (bacteriophages), proviruses are often referred to as prophages. However, it is important to note that proviruses are distinctly different from prophages and these terms should not be used interchangeably.
Common cold virus is difficult to cure because Unfortunately, antibiotics — medications that treat bacterial infections — cannot treat or cure a common cold. That's because colds aren't caused by bacteria. Some people report that they've had a cold, took antibiotics, and felt better after a few days of the medication.

What is one of the results of an increase in the amount of greenhouse gases in the atmosphere?
А
increased overall ocean salinity
B
decreased global polar ice melting
с
increased overall atmospheric humidity
D
decreased global surface temperatures
Answer:
C) Increased overall atmospheric humidityIncreasing overall atmospheric humidity is the result of an increase in the amount of greenhouse gases in the atmosphere. Therefore, option C is correct.
What are greenhouse gases?The gases that trap heat in the earth's atmosphere are referred to as greenhouse gases. The earth's surface warms during the day when the light beams through the atmosphere. The earth's surface cools at night, redistributing heat into the atmosphere. However, part of the heat is captured by the atmosphere's greenhouse gases.
Due to minute concentrations of water vapor (H2O), carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) in the atmosphere, the Earth has a natural greenhouse effect.
Increasing overall atmospheric humidity is the result of an increase in the amount of greenhouse gases in the atmosphere. Therefore, option C is correct.

How does natural selection change the frequency of genes or traits over many generations? Biology students conducted an experiment mimicking genetic variation and coloration. Students used different colored beans to represent animals that might be prey: mice, for example. A student in each group was the predator: a hawk. Beans (mice) were randomly scattered on multicolored floor tiles, each color within four tiles. The hawk collected mice (beans) for 10 seconds. Mice not eaten reproduced. Three generations of data a shown in the table.
Genetic variation helps to drive natural selection and potentially, evolution. Red, white, and striped beans (mice) represent offspring that are the product of meiosis and sexual reproduction. Black and speckled beans (mice) are the result of mutations. Using the student data analyze the effects of these mutations on natural selection.
A) The color mutations provided a survival advantage to these two populations of mice.
B) The advantage of the mutations is dependent on the environment and external conditions.
C) While mutations provide genetic variation they did not play a role in natural selection.
D) The speckled mutation provided an advantage while the black mutation was a disadvantage for survival.
Answer:
D) The speckled mutation provided an advantage while the black mutation was a disadvantage for survival.
The speckled mutation provided an advantage while the black mutation was a disadvantage for survival.
Natural selection refers to the observation that organisms that are more suited and adapted to their environment live long enough to survive and reproduce thereby passing on their favorable characteristics to their offspring.
The mutation in which the mice became speckled was shown to be an advantage from the table. Hence, the speckled mutation provided an advantage while the black mutation was a disadvantage for survival.

Answer:
In the alveoli, where there is high pO2, low pCO2, lesser H+ concentration and lower temperature, the factors are all favourable for the formation of oxyhaemoglobin, whereas in the tissues, where low pO2, high pCO2, high H+ concentration and higher temperature exist, the conditions are favourable for dissociation of oxygen from the oxyhaemoglobin. This clearly indicates that oxygen gets bound to haemoglobin in the lung surface and gets dissociated at the tissues

What are temperate grasslands?Temperate grasslands are biomes characterized by vast expanses of open grasslands with few trees or shrubs. These ecosystems experience a wide range of temperature fluctuations between seasons, with hot summers and cold winters. As a result, animals that live in temperate grasslands have evolved adaptations that enable them to survive in this challenging environment. One of the most common adaptations of grassland animals is the ability to dig burrows. Burrows provide shelter and protection from predators, as well as a stable microclimate for animals to live in.
Hence, structures to dig burrows are a common adaptation for animals that live in temperate grasslands, as is present in the first option.
