Marine biologists are studying stickleback fish populations. There are two distinct variations in the sticklebacks based on phenotypes. They are found with the three spines more commonly in marine ecosystems while they are more commonly found without the three spines in freshwater ecosystems. This has been observed in many marine and freshwater ecosystems across the globe. What explains the variation seen in the image here across different aquatic ecosystems?

Answers

Answer:

Presence of predators.

Explanation:

Presence and absence of predators is the main cause of the presence of spines on stickleback fish populations because these spines helps in the protection against predators. The stickleback fish populations that lives in marine ecosystem have spines because there are many predators are present while on the other hand, stickleback fish populations of freshwater ecosystems have no spines due to no predator so they acquire the adaptation of having no spines.

In this exercise we have to explain the variations of the aquatic system, so we have to:

In this case, as long as a large increase in a specific population of fish takes place, we know that the predators of this system are needed.

What factors interfere in an ecosystem?

They are:

Biotic factors: producing beings (plants and algae), consuming beings (herbivores and carnivores) and decomposing beings (fungi and bacteria). Abiotic factors: water, light (light energy), heat (thermal energy) and nutrients (chemical substances).

Answers

Answer: B

Explanation:

Edwin Hubble was an American astronomer who played a crucial role in collecting evidence to support the theory that the universe is constantly expanding outward and is not simply static. He used light from distance stars to calculate their movement.

Meanwhile, around this same period of time, a Russian physicist by the name of Mikhail Lomonosov worked tirelessly in his lab studying different chemical reactions. Lomonosov would later help in developing the Law of Mass Conservation which states that during a chemical reaction the total mass of the substances before the reaction is equal to the total mass after the chemical reaction.

How are the methods used in the pursuit of a scientific explanation different between Edwin Hubble and Mikhail Lomonosov?


A) Edwin Hubble carefully identified and manipulated variables to answer questions; Mikhail Lomonosov made observations about the natural world.

B) Edwin Hubble made observations about what he studied; Mikhail Lomonosov did not

C) Edwin Hubble and Mikhail Lomonosov both used scientific equipment and collected evidence

D) Edwin Hubble made observations about the natural world; Mikhail Lomonosov carefully identified and manipulated variables to answer questions.

Answers

Answer:

C

Explanation:

These type of questions leave a great deal to be desired. There is no mention of which way Hubble used and manipulated data. He studied the variations in light to determine his conclusions.

Nor is there any mention of what Lomonosov did to come to the conclusion that conservation of mass is a constant.

We don't know what was done to get the results. Hubble was studying the universe; the conclusions made by Lomonosov depended on lab equipment that was very delicate (I'm assuming). I doubt he manipulated variables. He measured what he got.

I think the answer is C, but the question has so many assumptions that it is hard to know what answer to pick.

How does wind affect the amount of rain?

Answers

Answer:

please give me brainlist and follow

Explanation:

The rainfall loss rate increases as the wind speed increases and/or the rainfall intensity decreases.

Air Currents

Prevailing winds bring air from one type of climate to another. For example, warm winds that travel over water tend to collect moisture as they travel; the water vapor in the air will condense as it moves into colder climates, which is why temperate coastal areas often receive heavy rainfall.

Answers

Answer:

Long tail and narrow head.

Explanation:

A sperm cell is adapted to reduce friction as it swims by having long head, narrow tail and enzymes. These features of sperm provides ability to swim straight to the egg cell. Long tail helps the sperm cell to swim towards the egg cell, narrow head of sperm cell make the sperm cell for faster swimming towards the egg cell and enzymes present in the head of the sperm helps break through the egg cell membrane so we can say that the long tail and narrow head of sperm cells helps in faster swimming.

A cup is surrounded by air in room temperature
Describe the energy transfer between the water and air if the system is at equilibrium

A.Energy is transfers from air to the water

B. Energy transfers from water to the air

C. Energy transfers back and forth between air and water

D.None of the above

Answers

I think the answer is D. I’m bot sure though I learned about this last year so my memory on it isn’t the best

The energy transfer between the water and air if the system is at equilibrium does not carry any transfer of energy. So, the correct option is D.

What do you mean by Equilibrium state?

Equilibrium may be defined as a condition in the course of a reversible chemical reaction in which no net change in the amounts of reactants and products occurs.

When the system is at equilibrium, the energy transfer between water and air surrounding the cup does not take place. It will only take place when there is a difference between the concentration of two solutions or objects.

Therefore, the energy transfer between the water and air if the system is at equilibrium does not carry any transfer of energy.

In your opinion, what are the three most important factors we can use to determine how developed a country might be? Explain your answers in a few sentences. << Read Less

Answers

Answer:

The correct answer is -  GDP nominal, human resources and right, and GDP per capita.

Explanation:

The three major and most reliable factors about determining the development of a country out of all the indexes are GDP nominal, the human rights index, and the GDP per capita.

The economy and production of a country can be shown by the GDP nominal if it is showing progress or declines.

The Average income of the citizen of the country is exhibited by GDP per capita to examine if the wealth of the country shares that gives an idea about rich, poor or the middle class.

The human rights index defines the basics of life expectancy and the rights they have that decides the happiness.

What role does vasoconstriction play in thermoregulation​

Answers

Explanation:

In endotherms, warm blood from the body's core typically loses heat to the environment as it passes near the skin. Shrinking the diameter of blood vessels that supply the skin, a process known as vasoconstriction, reduces blood flow and helps retain heat.Thus, the blood returning to the heart has not lost much heat.

Answer:

Reduces blood flow and helps retain heat thus the blood returning to the heart has not lost much heat

If the blockage is removed from the blood vessel, what will happen to blood flow after removal?

Answers

Answer:

the blood would stop pumping, because the blockage allows the blood to move one way, but when there is not blockage, the blood would enter from both ways making it impossible to regulate

Evaluate the use of stem cells from a patients own bone marrow instead of stem cells from an embryo. You must give a conclusion.

Answers

Answer:

The stem cells are the special cells that can develop into different types of specialized cells. There are two major stem cells in the body. The one is an embryonic stem cell that presents in the initial divided few cells that have the ability to develop into any type of specialized cells.

The other one is adult stem cells such as Bone marrow that contains two types of stem cells: hemopoietic which has the ability to produce all three types of cells, and stromal that able to produce special muscles and bones due to their limited ability to develop specialized cells or multipotent.

Thus, embryonic stem cells are more useful than adult stem cells.
