1. What causes the inside of the cell to be more negative compared to the outside of the cell? Resting Potential, Action Potential
Answers
Answer:
Resting potential
Explanation:
This is because , the resting potential is negative in side of the cell because it has more negative charge inside than outside due to accumulation of alot of sodium and potassium ions. when an axon is at rest in the cell, the anions produce negative charge, the sodium pumps eject sodium out of the cell and potassium is injected in, and the sodium gates and potassium gates are all closed.
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.
If the blockage is removed from the blood vessel, what will happen to blood flow after removal?

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 is the purpose of the tiny hairs called cilia in your nose?
⦁ What are the purposes of the pharynx?
⦁ What is the purpose of the epiglottis?
⦁ How is the respiratory system linked to the cardiovascular system
Answers
Answer:
1. The respiratory system allows us to breathe . They bring oxygen into our body and remove carbon dioxide from the body .
2. Tiny hairs called cilia protect the nasal passageways and other parts of the respiratory tract, filtering out dust and other particles that enter the nose through the breathed air.
3. The throat (pharynx and larynx) is a ring-like muscular tube that acts as the passageway for air, food and liquid. It is located behind the nose and mouth and connects the mouth (oral cavity) and nose to the breathing passages (trachea [windpipe] and lungs) and the esophagus (eating tube).
4. The main function of the epiglottis is to seal off the windpipe during eating, so that food is not accidentally inhaled.
5. The heart pumps blood to the lungs for oxygenation and the lungs then give the heart back oxygen rich blood to be transmitted to the whole body

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.

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.
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.
Which describes organisms going into deep sleep for the winter?
A. Birds migrating
B. Animals hibernating
C. Trees losing their leaves

Answers
Answer:
Animals hibernating is the answer
Explanation:
Hiberntion is when animals sleep for months in the cold winter
When animals hibernate, it is usually in the winter. They store food with them for when they wake up.
An example is squirrels which store acorns near them when they go to hibernate
Birds migrating is usually to lay eggs
Trees losing leaves is usually so that they can store their precious nutrients like glucose
Insects during metamorphosis is when they change form, eg from a caterpillar to a butterfly

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.
