Water moves from an area of high concentration of water molecules across a semi-permeable membrane to an area of lower concentration of water molecules. b. Water moves from an area of lower concentration of water molecules across a semi-permeable membrane to an area of high concentration of water molecules. c. Water moves from higher concentration of salt molecules across a semi-permeable membrane to lower concentration of salt molecules. d. Both b and c e. Both a and c
Answer:
a. Water moves from an area of high concentration of water molecules across a semi-permeable membrane to an area of lower concentration of water molecules.
Explanation:
Osmosis is a physical phenomenon in which solvent molecules move through a semi-permeable membrane from a region with low solute molecules concentration to a region with high solute molecules concentration. Or in order word, osmosis is the flow of solvent molecules (example is water) through a semi permeable membrane, from a region of higher concentration, to a region of lower concentration of water molecules. Example of osmosis is the biological flow of water molecules into or out of the body cells through the cell walls, in response to the difference in the concentration of salts and minerals within and outside the cell wall.

Lipids provide about
kJ/g of energy and are stored in
A. 19, granules
B. 36, triglycerides
C. 38, adipose tissue
D. none of these is correct
Answer:
C. 38, adipose tissue
Explanation:
Lipids/fats are one of the three energy storing biomolecules in living systems; the other two being carbohydrates and proteins. Three of them supply energy when oxidized but the amount of energy differs with lipids providing the most amount of energy.
Lipids provide 9 calories of energy per gram when oxidized, which is about 38Kj/g (where 4.2kJ = 1 calorie). Also, lipids or fats are stored throughout the body, specifically in connective tissues called ADIPOSE TISSUES.

How do catalysts affect the energy of reactions?
Answer:
They affect the energy of reactions by allowing the reactions to use less energy.
Explanation:
Catalysts help speed up the rate of a reaction. Since energy is used to undergo a reaction, if a catalyst is present, it will help the reaction speed up, allowing it to use less energy without changing the reaction reactants or products.

acteriophages were labeled with radioactive phosphorous (32P) and sulfur (35S). The labeled bacteriophages were then allowed to infect their host cells. At the end of the experiment, the 32P label was found only inside the host cells and the 35S label was found only outside the host cells. This experiment shows that:
Answer:
They concluded that DNA is a genetic material.
Explanation:
This experiment shows that the DNA is genetic material. For performing experiments, the DNA of bacteriophages is labelled with radioactive phosphorous (32P) and proteins were labelled with sulfur (35S) in order to detect the action of bacteriophages. The bacteriophages attack on the bacteria by inserting its DNA in the bacteria. We can see this because radioactive phosphorus is present in DNA of bacteriophages while the protein did not enter into the bacteria and remain outside the cell and we can see it because protein is made up of sulphur.

What is adaptation?
Adaptation is a long-term or short-term change or modification of the body to survive and match the environmental conditions. Adaptation is necessary for every organism to increase its population.
Adaptation is categorized into different types according to the places where animals and plants live. Examples of adaptation are desert plants having thick leaves or no leaves to save water, and snow animals being white to blend in.
The animals living in very cold regions, like the arctic and Antarctica, have white fur to blend with the environment and save from predators.
Thus, the correct option is D. Fur, which blends in with snow.

Hypothesize about tumor growth. Scientists have shown that tumor growth is an example of positive feedback loops. Why is tumor growth an example of positive feedback? In your answer elaborate using the following terms stimulus, receptor, control center, effector, response.
Answer:
The connection between cancer cells stimulates uncontrolled proliferation and tumor growth
Explanation:
In the tumor, cancer cells are interconnected by different types of proteins, which may act as receptors or amplify oncogenic signals. For example, in breast cancer, it has been shown that oncogenic cells are often connected through E-cadherin proteins that mediate their adhesion, thereby stimulating the cell movement and invasion (characteristic of tumor metastasis). In this case, E-cadherin membrane proteins function by enhancing effector response in cancer cells. The nucleus acts as the control center of the cell that modulates the expression of tumor suppressor genes in order to inhibit tumor metastasis.

What is true about the most recent ice age?
O A. All life on Earth became extinct.
O B. It occurred during the Precambrian era.
O C. Sea levels rose over 300 feet.
D. Land bridges existed that are now underwater.
The truth about the last ice age: D. There was now a submerged overpass.
An ice age also called an ice age, is a geological period in which thick ice sheets cover vast land areas. These massive ice ages could last for millions of years and could radically change the surface topography of entire continents.
There have been several major ice ages in Earth's history. The amount of sunlight reaching Earth over thousands of years varies considerably, especially at the North Pole and its surrounding northern latitudes. When less sunlight reaches northern latitudes, temperatures drop, more water freezes into ice, and the Ice Age begins. This ice age began about 2.6 million years ago in a period known as the Pleistocene epoch and lasted until about 11,000 years ago. Like everything else, the Last Ice Age brought about a series of glacial advances and retreats. In fact, we are technically still in the Ice Age.

Why don’t populations of organisms that reproduce asexually have the same genetic variation as populations that reproduce sexually
Answer:
Asexual reproducing populations only get their genetics from a single parent, meaning that they all have the exact same DNA/RNA, while sexually reproducing populations have two parents meaning they get genetic code from two parents instead of one, therefore they have more variance. This variance is also the reason sexually reproducing populations are usually harder to wipe out due to variance.
What connection do all living things have with each another
Answer:
they all have cells
Explanation:
each living thing has cells that help them survive and help their body work well.
Answer:
All organisms need food for the energy required to live and grow. They all excrete (get rid of) waste products, and detect changes in their surroundings and respond to them. All living organisms follow a LIFE CYCLE of growth and development, reproduction, and death. One thing all living things have in common is that all living things have cells, performing the functions necessary for an organism to survive in its environment; even the most primitive of life forms, bacteria, consists of a single cell. All living things also use energy, grow and reproduce.

The correct answer is (A.) A convergent boundary is formed.
Explanation:
Edge 2021
A convergent boundary is formed which is modeled in the diagram. So, the correct option is A.
What is Convergent boundary?An location on Earth wherein two or more continental crust plates clash is known as a convergent boundary. Subduction is the inevitable sliding of one plate beneath the other. The Wadati-Benioff zone is a plane with a high frequency of earthquakes, can be used to designate the subduction zone.
When two plates are advancing towards one another and colliding, it is called a convergent boundary, also known as a destructive boundary. At these borders, there is enough pressure and friction for the Earth's mantle material to melt, which results in nearby earthquakes and volcanoes.
