Answer:
Law of the Conservation of Mass
Explanation:
During a chemical reaction, the mass of the reactants and products must be the same. The total number of atoms stays equal. Elements cannot magically appear or disappear in a reaction, so you have to account for all of them
The same amount of atoms needs to be shown on both sides because of the Law of Conservation of Mass.
An atom can be defined as the fundamental unit of matter which is the smallest particle of an element that can take part in a chemical reaction.
There are some law guiding the state of matter which include:
The Law of Definite ProportionsThe Law of Conservation of compoundsThe Law of Conservation of MassThe Law of conservation of mass states that matter can neither be created nor destroyed in course of any chemical reaction, but changes from one form to another.
Therefore, atoms don't just magically appear or
disappear from the reactant or product sides because of
law of Conservation of Mass.

Why would blood volume play a role in the amount of time a mammal can stay under water?
Answer:
The answer is that they store oxygen in their blood, and in their muscles rather than in their lungs. Marine mammals have a very high blood to body volume ratio. The mammalian diving reflex allows mammals to lower their heart rate and ultimately survive submersion in water for extended periods of time.
Explanation:
The reason why blood volume played a vital role should be explained below.
Role of blood volume:In the case when the oxygen is stored in the blood & in their muscles instead of their lungs so this represents the role of blood volume. Also, marine mammals contain a high blood-to-body volume ratio. It permits the mammals for lowering the rate of heart and survive the submersion in the water for extension of the time. This is the main reason.

What provides energy to muscles and helps keep
them strong?
Answer:
The source of energy that is used to power the movement of contraction in working muscles is adenosine triphosphate (ATP) – the body's biochemical way to store and transport energy. However, ATP is not stored to a great extent in cells. So once muscle contraction starts, the making of more ATP must start quickly.
Answer:
adenosine triphosphate (ATP)
Explanation:
Creatine phosphate can supply the energy needs of a working muscle at a very high rate, but only for about 8–10 seconds.

Answer:
I'm not 100% sure but my beat bet is: Carbon moves from plants and animals to soils
Answer:
On grazed land, cattle trample some of the plants into the soil increasing carbon content. In forested areas, dead plant material is incorporated into the soil by worms and other soil organisms. On cropped land, it doesn't very much, causing soil degradation.

What is the importance of knowing cranium size, dentition, number of toes/fingers, flexibility of joints, locomotion styles, body size, the skeleton, etc. Of primates?
Answer:
Important for identification.
Explanation:
Knowing the cranium size, dentition, number of toes/fingers, flexibility of joints, locomotion styles, body size, the skeleton, etc. of primates is very important to identify the specie of primates group. Different primates have different cranium size, dentition, fingers or toe's number, flexibility of joints, locomotion styles, body size, the skeleton etc so these information helps in identification and grouping of primates during classification.

The flocks all started with 10 birds. Flock
was the most successful at feeding, so it will have the greatest number in the second generation. Flock
was the least successful at feeding and has shrunk the most.
In this scenario, natural selection is affecting many populations of birds with different beak morphologies, which affects how well they can eat the available foods. Each flock initially consisted of 10 birds, but over many generations, natural selection favored some traits over others, changing the population size.
One flock, referred to as "Flock," had the greatest number of second-generation birds because it was the most successful at feeding. Another flock, known as "Flock," had the worst feeding results and has had the greatest shrinkage.

Your question is incomplete, most probably the complete question is:
The flocks all started with 10 birds. Flock was the most successful at feeding, so it will have the greatest number in the second generation. Flock was the least successful at feeding and has shrunk the most. With three foods available, natural selection has favored Flock , which has increased the most in the first three generations. Meanwhile, Flock has declined the most because its beak was the least successful phenotype for the food available.

An area of grassland is transitioning into a desert due to overgrazing of livestock. What will happen to the population of grass eating
native organisms in the area?
O A. The population will increase.
OB. The population will decrease.
C. The population will experience no change.
D. The population will decrease, then slowly increase.
Answer:A
Explanation:
Because n
Answer:the answer is B.the population will decrease.
Explanation:
The population will decrease because since the grassland is turning into a desert due to overgrazing, it will be causing the grass to die out, and since the grass is dying out, the grass eating native organisms population will start to go down as well because there will be no more grass to eat from, so therefore i think the answer is B. The population will decrease.

The table below shows the average monthly temperatures of four locations.
Based on the table, which of these locations is most likely situated near the ocean? (4 points)
Location A
Location B
Location C
Location D
Answer:
Location A
Explanation:
Coastal areas have milder temperatures since they are close to water and water retains heat better than land (it's harder to warm it up and harder to cool it down). Due to this property of water, the location with the least temperature fluctuation would be the answer. Location A has the smallest range between the highest and lowest annual temperatures, making A the best answer choice. I hope I helped and that it's not too late for you.

No predators are present.
There are no resources.
Answer:
There are plenty of resources.
No predators are present.
Explanation:
There r plenty of resources + no predators
Exponential population growth happens when there are plenty of resources and no predators are present.
What do you mean by Population growth?Population growth may be defined as the change in population per unit of time.
Exponential growth occurs in the population of continuous breeders. For example, some insects, humans, bacteria, etc.
Exponential population growth requires an enormous amount of resources in habitat and no predator influence.
Therefore, exponential population growth happens when there are plenty of resources and no predators are present.
