Answer:
D.
Explanation:
As the oxygen inside the cell is utilized by the cell for respiration, therefore the concentration of oxygen inside the cell decreases and the oxygen in the solution naturally diffuses inside the cells through simple diffusion.
What is dissolved oxygen?
Dissolved oxygen is the amount of oxygen that is dissolved in a particular solvent. The dissolved oxygen in water comes from the atmosphere. The aquatic plants that produce the oxygen also contribute to the dissolved oxygen in water bodies.
Aquatic organisms require dissolved oxygen for respiration as they cannot take up oxygen from the atmosphere. Oxygen in water can be measured as milligrams per liter or the percent saturation.
In the RBCs, the oxygen combines with the hemoglobin and is transported by hemoglobin-facilitated diffusion or through simple diffusion in which the oxygen crosses the plasma membrane and is transported to the blood plasma through diffusion.

PLEASE ANSWER ASAP: In the food chain- grass ---> grasshopper ----> bird ------> snake
Who would be affected the most?
Answer:
All would be affected but the snake would probably be most effected
Explanation:
If the bird was removed from the chain, the snake would have no valid food source leading to a decrease in population for the snakes.
Although the population of the grasshopper would increase because there is no birds to eat the grasshoppers the snake would probably still be most affected because they would all die off as they would have no valid food source
Deana is studying the table shown here, which lists the birthrate and death rate for several countries.
Country Birthrate
(per 1000 People) Death Rate
(per 1000 People)
Brazil 14.7 6.1
Cambodia 24.1 6.1
Italy 8.3 9.8
Mali 43.5 10.5
Venezuela 19.6 5.5
Deana applies the data in the table to calculate the rate of population increase or decrease of each country.
Which assumption is necessary for Deana’s calculations to be accurate?
A. The immigration and emigration rates of the countries are insignificantly small or approximately equal.
B. The immigration rates of the countries are much higher than the emigration rates.
C. The immigration rates of the countries are much smaller than the emigration rates.
D. The population is evenly distributed between rural, suburban, and urban areas.
In order to use only the birth and death rates to calculate the rate of population growth or decrease of a country, the immigration and the emigration rates must either be insignificant or approximately equal.
Population growth rateThe growth rate of a population is determined by the following equation:
Growth rate = (Birth rate - death rate) + (Immigration - Emigration)
Thus, if immigration is more or less equal to emigration or both factors are insignificantly small, the difference between the birth and death rates can be used to estimate the population growth.

I have to answer these questions with these graphs made how do i answer them
Answer:
A line graph is also used when there are two variables—but only makes sense when you're tracking changes over a continuous measurement (e.g., time, temperature, distance). Line graphs are especially useful for illustrating direction (i.e., peaks and dips) rather than magnitude.
Line graphs are used to track changes over short and long periods of time. When smaller changes exist, line graphs are better to use than bar graphs. Line graphs can also be used to compare changes over the same period of time for more than one group.

Some adaptations are helpful in one environment, but would be harmful in other environments. Ex) Thick fur, helpful in cold environment, but harmful in hot environments
Answer:
Thin fur is helpful in hot environments, but harmful in cold environments
The statement "Some adaptations are helpful in one environment but would be harmful in other environments. Ex) Thick fur, helpful in cold environments, but harmful in hot environments, is true.
What are harmful adaptations?Because they might alter how the body normally functions, some adaptations can be toxic or damaging to an organism. These are the kinds of maladaptations that can alter a population. They develop as a result of mutations or adjustments to the population's genetic makeup.
An organism adapts when it undergoes changes throughout time, frequently as a result of genetic mutations that happen by chance and are handed down to succeeding generations. Many diverse creatures have structural or behavioral adaptations that are advantageous to them physically.
Therefore, the statement is true.

Leaves falling from a tree ,what is explanation
Explanation
~ Cliché as it may sound, leaves falling from a tree is caused by the gravity of the Earth.
GRAVITY~ Gravity is one of the reason and the driving force that made the universe possible. It is the entity that enables the sun to hold planets together in the solar system; the reason why Earth is revolving around the sun just like the moon orbiting the Earth.
~ Gravity has to do with everything on Earth -- leaf falling from the tree, ball bouncing up and down, ocean waves, and stalactites facing downwards.
