The rainforest contains half of the Earth’s wildlife and at least two thirds of its plant species. It can hold great quantities of water and is very important to the planet’s water cycle. Rainforests remove vast amounts of CO2 from the atmosphere and replace it with oxygen. Which of the following statements best summarize the above information about rainforests?
a.
The majority of the planet’s oxygen is generated from the rainforest.
b.
Two-thirds of all plants originated from the rainforest.
c.
The rainforest is a major catalyst for the planet’s water cycle.
d.
The rainforest is important to life as a whole on the planet.
Answer:
D) The rainforest is important to life as a whole on the planet.
Explanation:
While the other options are true, the statment states that it is not only one of them. It is stated that the rainforest provides a habitat for for 1/2 of Earth's wildlife and 2/3 of it's plants. This proves that 'B) Two-thirds of all plants originated from the rainforest' is correct. But, it also states that the rainforest removes CO2 from the air and puts oxygen back out, proving that 'A) The majority of the planet’s oxygen is generated from the rainforest,' is also correct. 'C) The rainforest is a major catalyst for the planet’s water cycle' is also proven true because it is said that the rainforest holds great quantities of water, making it very important to the planet's water cycle. These are all important to the planet, making 'D) The rainforest is important to life as a whole on the planet,' the most accurate statement.

suggest how these synthetic plant growth substances spread through the plant
Answer:
Plant growth regulators may be synthetic compounds, such as IBA and Cycocel, that mimic naturally occurring plant hormones, or they may be natural hormones that were extracted from plant tissue, such as IAA.
Explanation:
Plant growth regulators may be synthetic compounds, such as IBA and Cycocel, that mimic naturally occurring plant hormones, or they may be natural hormones that were extracted from plant tissue, such as IAA.
What are synthetic plant growth regulators?
Plant growth regulators are substances that, when added in small amounts, modify the growth of plants, usually by stimulating or inhibiting part of the natural growth regulatory system. Synthetic plant growth regulators hold the promise of becoming important tools in efforts to increase the world food supply.
What are synthetic hormones in plants?
Synthetic plant hormones or PGRs are used in a number of different techniques involving plant propagation from cuttings, grafting, micropropagation and tissue culture. Most commonly they are commercially available as "rooting hormone powder".

explain how the age of the oceanic crust provided evidence for seafloor spreading
Answer:
The principle of seafloor spreading states that new ocean crust is always being formed, and that this crust is slowly carried farfar from its factor of starting place over a duration of time. The examine of the repeated reversal of the Earth's magnetic poles through the years has supplied convincing proof of seafloor spreading.

Nitrogen is an important element for which macromolecules? Why?
Answer:
Nitrogen in the reduced form is the major component of the three most important biological macromolecular structures: (i) proteins/polypeptides, (ii) DNA and RNA, and (iii) polymers of amino sugars.
There are four major classes of biological macromolecules - carbohydrates, lipids, proteins, and nucleic acids. Each are made up of different elements. Nitrogen is found in two of these macromolecules - proteins and nucleic acids.
Nitrogen is a naturally occurring element that is essential for growth and reproduction in both plants and animals. It is found in amino acids that make up proteins, in nucleic acids, that comprise the hereditary material and life's blueprint for all cells, and in many other organic and inorganic compounds.
Answer:
Proteins/polypeptides, DNA/RNA, and polymers/amino acids.
Explanation:
Nitrogen is EXTREMELY important for many macro molecular structures, and is found in the most important parts of the body. You need all of these things to keep you alive.

Which body systems help the respiratory system move gases between the lungs and the cells of the body?
Answer:
The Cardiovascular System
Explanation:
The respiratory system draws air into the lungs. Oxygen diffuses through the walls of the alveoli and across the walls of the capillaries where it enteres the bloodstream. The oxygen molecules are picked up by red blood cells, which are pumped through the blood vessels by the action of the heart. As the red blood cells carrying oxygen pass through capillaries near the cells, oxygen diffuses into the cells.
Answer:
The respiratory system collaborates with the circulatory system to deliver oxygen and remove metabolic waste. It also aids in blood pH regulation. Respiration is the process through which oxygen and carbon dioxide are exchanged between the atmosphere and the body's cells.

Describe THREE ways in which parenchyma cells are structurally suited for their
specific function
Answer:
Parenchyma cells are distinguished by their thin walls and the fact that they are alive at maturity. To sustain structure, collenchyma cells produce thicker secondary cell walls. Sclerenchyma cells produce tissues like bark and vascular tissue by thickening their walls and dying off as they mature.
Explanation:
Parenchyma cells are distinguished by their thin walls and the fact that they are alive at maturity. To sustain the structure, collenchyma cells produce thicker secondary cell walls. Sclerenchyma cells produce tissues like bark and vascular tissue by thickening their walls and dying off as they mature.
What are two functions of parenchyma?Parenchyma cells are actively metabolizing living cells present throughout the plant body. These cells have thin primary cell walls. Some of the functions of parenchymatous cells in plants are storage, photosynthesis, secretions, etc. The photosynthesizing parenchyma cells are mostly present in green leaves of plants and have green chloroplasts.
Some of the parenchymatous cells also serve to store metabolites such as oil droplets, starch grain, water, salts, etc. The secretion of resins, tannin, hormones, nectar, and other substances is done by specialized parenchymatous cells.
Thus, Parenchyma cells are distinguished by their thin walls and the fact that they are alive at maturity.

Answer:
None or Null
Explanation:
Long whiskers is AA(dominant)
short whiskers is aa(recessive)
parental generation:
AA aa
cross = Aa, Aa Aa Aa
