Answer:

Explanation:

When someone says the word "desert," what plant do you picture? You're probably
picturing the saguaro cactus. Saguaros are known for their long, tall branches that look like
arms. These branches don't start to grow until the cactus is 50 to 70 years old. The folds
along the saguaro's stem and branches are called pleats. What are they for? These pleats
store water for the cactus, which is important in the hot, dry desert. A desert plant's spikes
aren't just to keep animals away. They also help provide shade during the long hours they
spend in the sun.

How are many unicelled organisms. In addition , anything less than a cell is not alive. What do these statements imply about cells?

Answers

Answer:

The correct answer is - cells are the basic unit of life.

Explanation:

As it is given and also known that there are many unicellular organisms exists and they do not require the multicellular body to live their life or survival. Multicellular organisms are made up of various cells joined together to form a complex organization.

Anything less than a cell can not live or survive and also do not called a living entity. So, from above we can say the basic unit of the life is cell.

A. Have one group breed twice as often as the other.
B. Keep the two groups apart, but in identical ecosystems.
C. Force the two groups to breed with each other.
D. Have one group live with a much stronger predator.

Answers

Answer:

Hi, there your answer is D. Have one group live with a much stronger predator.

Explanation:

Having one group live with a much stronger predator will most likely increase the chances of speciation.

What is speciation?It is a process by which a new species of an organism is created.It occurs due to evolution.It occurs when a portion of population gets separated from the original population and evolves different characters that are heritable.Will speciation occur if :one group breeds twice as often as the other? No, because no selective force is acting on it.both groups are in identical ecosystem? No, since no reason for adapting and evolving a new character will be there.both groups interbreed? No, there is no competition, no struggle for existence and hence no evolution occurs.one group lives with a strong predator? Yes, since they will evolve evasive mechanisms and characters.

Why did Gregor Mendel choose to use purebred plants in his experiments?
A They reproduce sexually.
B They exhibit only one form of a trait.
C They have a variety of traits.
D They reproduce asexually.

Answers

Answer:

B

Explanation:

Gregor Mendel chooses to use purebred plants in his experiments because they exhibit only one form of a trait. The correct option is B.

What is Mendel's experiment?

Mendel altered pure pea plant lineages. First-generation hybrids (F1) displayed dominant qualities like purple flower color while hiding recessive traits like white bloom color.

But in second-generation (F2) pea plants, recessive characteristics returned in a 3:1 ratio (dominant to recessive). Every pea plant has both male and female reproductive organs, and they all typically procreate by self-pollinating.

This was crucial to make sure that there were no other factors influencing the result of the cross when he crossed two plants with different features.

Therefore, the correct option is B, They exhibit only one form of a trait.

In the simulation, when protein molecules were evenly distributed on both sides of the membrane, was the solution isotonic, hypertonic, or hypotonic? Which direction was water flowing?

Answers

Answer:

1. Diffusion is the process of a substance moving from an area of high concentration to an area of lower concentration. Osmosis is a type of diffusion where water moves across a semipermeable membrane still from an area of high concentration of water to an area of lower concentration of water. This corresponds to water moving from an area with a low concentration of solute to an area with a higher concentration of solute.

2.

a. A semipermeable membrane allows some substances to pass through it.

b. The plasma membrane of a cell allows small uncharged molecules to pass through it, but not large molecules and not charged ions.

3.

a. The protein molecules were evenly distributed on both sides of the membrane, so this solution was isotonic.

b. In an isotonic solution, water moves both in and out of the cell, which was observed in the simulation.

4.

a. The protein molecules were more highly concentrated on the inside of the cell, so this solution was hypotonic.

b. In hypotonic solutions, water moves into the cell to help dissolve the higher amount of solute inside the cell, which was observed in the simulation.

5.

a. A semipermeable cell membrane is important to allow some molecules, like proteins, to be more highly concentrated inside the cell than outside the cell. If the cell membrane were permeable, the molecules on the inside of the cell would exit the cell and be evenly distributed in the cell and in its environment.

b. If the cell membrane were not permeable at all, the cell would not be able to receive nutrients from its environment.

Explanation:

When protein molecules were evenly distributed on both sides of the membrane, the solution is isotonic.

In isotonic solution the concentration of  solutes on side remain same .There is no net gain or less of water in isotonic solution.

What will be the direction of water flow in isotonic solution?The water will flow freely  across the cell membrane without any change in the concentration of solutes.In isotonic solution the cell neither shrink nor swell because the water concentration will remain same.

Answer:

hmm I'd say something like "Solar and Wind energy systems are renewable sources and ultimately are healthier for the planet, the drawback is that other resources (i.e oil and coal) tend to be cheaper"

Answer:

Solar Energy:-

Benefits-

Solar power is completely cleanIt produces no air pollution, no water pollution, no greenhouse gas effects and carbon - free alsoNo harmful emissions are released when electricity is being produced by solar panels.It also reduces the need for finite resources.

Drawbacks-

Solar Energy Storage Is ExpensiveUses a Lot of SpaceIts Weather-Dependent, slthough solar energy can still be collected during cloudy and rainy days, the efficiency of the solar system drops.Initial cost of purchasing a solar system is fairly high.

Wind Energy:-

Benefits-

Wind is a domestic source of energyIt's a clean fuel sourceIt's sustainable and causes no harmful emissions. Wind energy is a green energy source and does not cause pollution.

Drawbacks-

Wind turbines are prone to noise disturbances.The wind is inconsistentWind turbines involve high upfront capital investment.Installation can take up a significant portion of land.
