expands. You have seen hot air balloons in which the air
inside the balloon is heated to make the balloon, basket,

Answer:

A dam that could allow fish to still pass through is a fishway/fish pass its a "fish ladder" that is structured on or around artificial or natural barriers to allow for fishes natural migration and the movement for potamodromous species.

The upper area that is still surrounded by cloud base because it will hold more moisture than the lower area.

The cloud base hypothesis was proposed to explain the widespread amphibian loss in the cloud forest.

If the lifting cloud base hypothesis to be correct, the part of the Monteverde cloud forest would likely be the least affected by the decrease in moisture is the upper area that is still surrounded by cloud base because it will hold more moisture than the lower area.

Thus, the answer is  "the upper area that is still surrounded by cloud base because it will hold more moisture than the lower area".

This is because testosterone is the hormone for se*x drive

Answer:

I think its "They can flood."

Explanation:

The reason for this is due to the fact that climate change mainly deals with warming up the earth because of a hole in the ozone. But, I may be wrong... Its an impact on freshwater sources after all.

Answer:

The main job of a leaf is to deliver nourishment for the plant by photosynthesis, the process of converting light energy into chemical energy. Chlorophyll, the substance that gives plants their characteristic green colour, retains light energy. The inside structure of the leaf is secured by the leaf epidermis, which is nonstop with the stem epidermis.

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.

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.

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".

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.

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.

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.

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.

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.

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.

Photosynthesis requires sunlight, carbon dioxide, and water as starting reactants. After the process is complete, photosynthesis releases oxygen and produces carbohydrate molecules, most commonly glucose. These sugar molecules contain the energy that living things need to survive.

During the process of photosynthesis plants break apart the reactants of carbon dioxide and water and recombine them to produce oxygen (O2) and a form of sugar called glucose (C6H12O6).

True

Are ocean currents warm?

They can be cold, warm, and hot. Warm ocean currents originate near the equator and move towards the poles or higher latitudes while cold currents originate near the poles or higher latitudes and move towards the tropics or lower latitudes. 

We can divide ocean currents into two categories based on temperature: warm and cold currents.

Ocean currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth's surface.
