Answer:
ii) In terms of the shape of the plant, water is important to plants as the hydration of the cells of a plant allows the cell walls to retain their shape and thus give structure to the plant.
iii) In terms of hydrolysis and dehydration, water is essential to plants because water is not a photosynthesis reactant and respiration product.

Why would dark moths have an advantage?
Answer:
To study these moths, Dr. Kettlewell placed light and dark moths on the trunks of trees where he could observe them. The same birds would find the dark moth twice as often if the bark on the tree was light. This supported the idea that dark moths had a survival advantage in a dark forest.

PLEASE I NEED HELP Explain how the process of mitosis is essential to the regeneration of tissue using stem cells
Answer:
Mitosis is essential to the regeneration of tissue because during Mitosis, cells replicate to create a daughter cell that is the exact copy of the parent cell.
Explanation:
The reason this is so important is because stem cells can develop into nearly any cell type. Mitosis allows these cells to replicate the exact cell type needed (in this case, tissue), and create a daughter cell that has the same exact components and characteristics of the parent cell.
PLEASE ANSWER THESE QUESTIONS COMPLETELY!!! WILL MARK BRAINLIEST!!!
Questions:
A. Is the suspect guilty of the crime?
B. How do you know?
Answer:
A. No
B. because, the suspect doesn't add up to any of the DNA of the killer, victim, or the control, so no the suspect is definetly not guilty and is definetly not the killer. It just wouldn't add up right, none of the other's DNA matches to the suspect, leaving the suspect as not guilty but inisent and doesn't lead or match that suspect to in any way the killer. In other words the killer and suspect don't link in any way!

Answer: age, smoking habits, and size/weight
Explanation:
The older you get, the weaker you'll be, so your breathing will be effected.
If you smoke then your lungs will be effected which will ultimately have an affect your breathing.
If you're really heavy (ex. Over weight) then you will get tired more easily, which will effect your breathing rate.

How do genetics (genetic predisposition) and the environment work together to cause substance abuse in individuals? What is the likely role of epigenetics in this process?
Answer: The drug abuse is influenced by the environment and exerts influence on the gene expressions.
Explanation:
The genetic make up of the person is decides, which genes will be expressed and develop a trait in an individual. But this genetic expression can be influenced by the environmental factors like food, exposure to sunlight, and others. This study which relate environment with the genetic make up is called epigenetics. No person is drug addict by birth but the consumption of drug can influence the genetic make up and traits in a abuser. So here, the environment is influencing the genetic basis of a abuser.

Which situation is a good example of the transfer of energy through radiation?
A. Energy passes from one person’s hand to another person when they shake hands.
B. A snake’s body temperature increases when the snake lies in the Sun.
C. Warm air that is less dense rises to the ceiling of a room.
D. A fan cools the CPU in a computer.
Radiation has been the mode of thermal energy transfer from a source. "A snake’s body temperature increases when the snake lies in the Sun" is an example of radiation. Thus, option B is correct.
What is radiation?Radiation has been the type by which the thermal heat energy passes from the source to the other site. It has been independent of contact and involves traveling in space with the equivalent speed of light. Unlike conduction and convection, radiation does not need matter.
The particles tend to move in space like the sun's rays heating the earth. When a snake lies in the sun its body temperature rises due to tradition as the solar energy from the sun (high temperature) moved in space to the lower temperature (snake's body).
Therefore, option B. heating the snake's body under the sun is an example of radiation.

If the Universe was born at the Big Bang, what existed before then
Explanation:
In the beginning, there was an infinitely dense, tiny ball of matter. Then, it all went bang, giving rise to the atoms, molecules, stars and galaxies we see today.
Or at least, that's what we've been told by physicists for the past several decades.
But new theoretical physics research has recently revealed a possible window into the very early universe, showing that it may not be "very early" after all. Instead it may be just the latest iteration of a bang-bounce cycle that has been going on for … well, at least once, and possibly forever.
Of course, before physicists decide to toss out the Big Bang in favor of a bang-bounce cycle, these theoretical predictions will need to survive an onslaught of observation tests.
The initial singularity is a singularity predicted by some models of the Big Bang theory to have existed before the Big Bang and thought to have contained all the energy and spacetime of the Universe.
The burrowing owl is found in dry, open areas such as grasslands, prairies, savannas, deserts, farmlands, golf courses, and urban areas throughout most of western United States and Florida, Central America, and most of South America. It makes its home in burrows of other animals and primarily eats insects and small rodents. As humans build more cities, nearby burrowing owl habitats change due to destruction of burrows and loss of prey. Which is the least likely outcome of the habitat changes that are described?

What two simple machines is a stapler made up of?
1. wheel and axle and lever
2. lever and pulley
3. wedge and screw
4. wedge and lever
Answer:
4. wedge and lever
Explanation:
Simple machines are mechanical devices which make our work easier. Examples are : lever, wedge, wheel and axel, pulley, screw and an incline plane.
A stapler is a made up of a level which is the handle part and a wedge which are the staples.
A pulley is a simple machine that has one or more wheels connected with a rope in a loop to make lifting of loads easier because it changes the direction of force applied/pull thus multiplying the force applied. A stapler does not have the wheel and the rope thus answer choice 1 and 2 are incorrect.
A screw is a simple machine that applies torque on a shaft to produce a large axial force on the load. It utilizes the conversion of rotational motion to a linear motion and a torque to a linear force. A stapler mechanism does not involve rotational motion or rotational force, hence answer option 3 is incorrect.
A stapler is made up of a combination of two simple machines: the wedge and the lever. The correct option is 4.
A stapler utilizes a wedge to perform its primary function. The wedge is the part of the stapler that drives the staple through the paper. It has a sharp, triangular shape that allows it to exert a large amount of force over a small area, making it easier to pierce through the materials.
The stapler also incorporates a lever mechanism. The lever is the long arm of the stapler that is pushed down to drive the wedge and staple into the paper.
By applying force at one end of the lever, a mechanical advantage is gained, allowing the user to apply a smaller force to produce a greater force output at the other end, making it easier to staple multiple sheets of paper together.
Therefore, The correct option is 4.

Answer:
Holmes proposed that the continents, which “floated” on the Earth's mantle, moved with the convection flow of the magma (hot semifluid below the Earth's crust). The mechanism of continental drift is like the flow of branches floating in the moving waters of rivers, as shown in Figure 3-11.4.
