A team of scientists conducted a study of grassland ecosystem and estimated the total energy at each tropic level. Their data is
MakcuM [25]

Answer:

The relationship between tropic levels and energy is that tropic levels contain a certain amount of energy depending of which level they are, the lowest tropic level will have the highest amount of energy, whilst the highest tropic level will have the lowest amount of energy.

The role of the organisms in the first tropic level is to produce food since they are autotrophs, these organisms do not rely on others for food. the organisms in the second level will control the amount of primary producers and will serve as food for tertiary consumers. The role of the organisms in the third level is to get food from secondary consumers so they don't overpopulate and affect primary consumers more than they have to.

Energy availability changes at each level because of the 10 percent rule. As you go higher, only 10 percent of the energy can actually be consumed by the consumer in the next level.

How many times larger is the number of hydrogen atoms than oxygen atoms in a molecule of water, H2O? ______ b. Is this number th
garik1379 [7]

Answer:

The correct answer is- A) two, B) yes, the number is the same as monosaccharides.

Explanation:

There are three atoms are present in a molecule of water which includes two atoms of the hydrogen and one atom of the oxygen. The hydrogen atom is two times larger in the number of the oxygen atom in a single molecule of the water.

In monosaccharides, the ratio of the atoms of carbon, hydrogen, and oxygen is 1:2:1 which means one hydrogen atom would be twice in the number of the carbon and oxygen atoms in a single molecule of monosaccharide molecule.

Thus, the correct answer is - A) two, B) yes, the number is the same as monosaccharides.

what determines the difference in speed of contraction of the different types of skeletal muscle cells?
zhuklara [117]

Muscle fibers can be divided into two general categories: Category I, which is sluggish, and Type II, which is quick.There are three primary fiber types in type II, which is further divided into type IIA (oxidative) and type IIX (glycolytic).These fibers exhibit comparatively unique features in terms of metabolism, contractility, and motor units.

<h3>Which cell types make up skeletal muscle?</h3>

These cells to make up muscular tissue are referred to as myocytes, or muscle cells.The human body contains three different types of muscle cells: cardiac, skeletal, or smooth.

<h3>How many different types of cells exist?</h3>

Your body has roughly 200 different kinds of cells.These cells help to build your tissues and organs as well as your immune system, which works to protect your body.Your body regularly replaces its dead cells with new ones.
