Will a person living 100 years from now have the same needs as you do today
Answer:
To some extent, things like hygeine, shelter, warmth, nutrition, and all those basic needs will still be needed, but as technology advances in the modern age, we may see that things we have no may become obselete in the future. Things are always evolving and improving, thus a person living 100 years from now may not have the same needs as you do today.

What will most likely happen to cells that r placed in fresh water?
Answer:
When animal cells are put in fresh water, water diffuses/moves into the cell, if too much water moves in the cell will burst. If you put a freshwater fish in salt water its cells would lose water and shrivel because the water has more salt than its cells.

Discuss how the structures of the different chambers and vessels of the heart relate to their functions.
Answer:
Found this off of google, "The heart works as two pumps, one on the right and one on the left, working simultaneously. Blood flows from the right atrium to the right ventricle, and then is pumped to the lungs to receive oxygen. From the lungs, the blood flows to the left atrium, then to the left ventricle.:

Explanation:
Cactus was introduced to Australia and quickly spread over millions of acres of land. A parasitic moth which preyed on and killed the cactus was then introduced to slow the spread.
Which of the following graph best describes the changes in population growth of the cactus? (bafora and aftar introduction of the moth)
A. 1
B. 2
C. 4
D. 5
Answer:
D)4
Explanation:
The graph has to have exponential growth in the beginning, ruling out 3. Then, the paragraph states the moth was introduced to slow the spread. 1 is all over the place and inconsistent, and 2 is basically taking the cactus away. 4 is leveling out the exponential growth, so it's 4
The graph that best describes the changes in population growth of the cactus before and after the introduction of the moth is four.
What do you mean by Population growth?Population growth may be defined as the increase in the number of individuals in a population over a certain period of time in a given area.
Graph four describes the phenomena of exponential growth, which means that before the introduction of the moth the population of cactus rose rapidly. But as the moth was introduced, the population of cactus slows down not completely decreases.
Therefore, the graph that best describes the changes in population growth of the cactus before and after the introduction of the moth is four.

The main challenge faced by the first land plants was access to _______. Plants responded to this challenge by developing _________.
1st blank: - Oxygen
- Water
- Sunlight
2nd blank: - Vascular tissue to transport materials throughout the plant
- Green chloroplasts
- Leaves with openings for gas exchange
Answer:
1.Water
2.vascular tissue to transport materials throughout the pant
Explanation:
I just took the test.
The main challenge faced by the first land plants was access to WATER. Plants responded to this challenge by developing vascular tissue to transport materials throughout the plant.
The land plants evolved to maintain life in dry conditions because the land is an environment where water is a limited resource.The plant vascular tissues include phloem and xylem, which work together to move substances (including water) within the plant.Xylem transports water from the roots up to other plant tissues, whereas phloem moves sucrose between the leaves and other plant tissues.In conclusion, the main challenge faced by the first land plants was access to WATER. Plants responded to this challenge by developing vascular tissue to transport materials throughout the plant.

Match the events to each phase of the cell cycle. What is the correct phase of the cell cycle description: Cells grow at a rate that varies between the two cell types. Cells do most of their growing during this phase.
Answer:
The phase of the cell cycle description corresponds to the interphase, specifically, the G1 stage.
Explanation:
The interphase is the previous step before mitosis occurs. The interphase is formed of the G1, S, and G2 stages.
During the G1 stage, it occurs a high and intense biochemical activity. The cell duplicates its size, and the organelles and other molecules and cytoplasmatic structures duplicate too. Some structures, such as microtubules and actin filaments, are synthesized from zero. The endoplasmic reticulum increases and produces a membrane for the Golgi apparatus and vacuoles, lysosomes, and vesicles. During this stage, the pair of centrioles separate, and each centriole duplicates.
The stages S and G2 follow the G1. Once the whole interphase is completed, mitosis occurs.
The correct phase of the cell cycle description given is - G1 phase of interphase.
The interphaseIt is the phase in the cell cycle that has three stages G1, S, and G2. The most of the cell lifetime the cells are in interphase and in interphase the G1 phase.
G1 Phase
In this subphase, the rate of cell growth varies that depends on the type of the cell. The cell grows and cellular structures are doubled by protein and mRNA synthesis.

Suggest why epithelial cells have many mitochondria.
Answer:In particular the epithelial cells lining the small intestine. ... They will therefore have a large surface area provided by the microvilli and due to the need for active transport across their cell membranes they will contain a large number of mitochondria providing them with ATP.
Explanation:
I’m Diffrent
Epithelial cells have many mitochondria because such cells desperately have high levels of energy output and significantly require the ATP that is considerably synthesized by mitochondria.
What are Mitochondria?Mitochondria may be defined as a double membrane-bound cell organelle present in the cytoplasm of the cell. Mitochondria are known as the "Powerhouse of the cell" because the energy required for various activities is produced by this specific cell organelle in the form of ATP.
The epithelial cells of organs like lungs, alveoli, intestines, kidneys, etc. facilitate the absorption of nutrients along with gases that remarkably provide a filtration barrier. These processes necessarily require high levels of energy output.
Therefore, epithelial cells have high levels of energy output and significantly require the ATP that is considerably synthesized by mitochondria.

Where is the energy to make ATP
coming from?
Answer:
The energy for the synthesis of ATP comes from the breakdown of foods and phosphocreatine (PC). Phosphocreatine is also known as creatine phosphate and like existing ATP; it is stored inside muscle cells. Because it is stored in muscle cells phosphocreatine is readily available to produce ATP quickly.
Answer: glucose
