Answer:

<u>C</u>

Explanation:

Kinetic Energy formula :

<u>K.E. = 1/2mv²</u>

<u />

=============================================================

Given :

⇒ mass = 0.17 kg (needed)

⇒ distance = 20 m (not needed)

⇒ velocity = 22 m/s (needed)

============================================================

Solving :

⇒ K.E. = 1/2 × 0.17 × (22)²

⇒ K.E. = 11 × 0.17 × 22

⇒ K.E. = 1.87 × 22

⇒ K.E. = 41.14 ≈ <u>41 J</u>

A mutation that results in a single amino acid substitution in the active site of an enzyme
Nikolay [14]

Answer:

May alter the specificity for its substrate

Explanation:

The active site of an enzyme refers to the specific region of an enzyme that serves as the binding site for its one or more substrates. Binding of substrates to the active site of their enzymes is required for catalysis. Enzymes are highly specific for their substrates. Type of amino acids present in the active site of the enzymes and their interactions with substrates regulate the specificity of the enzyme. If a mutation substitutes the amino acid of the active site, it may increase or decrease the specificity of the enzyme for its substrate.

Explain how the elements that form clouds are conserved during the carbon cycle.
Diano4ka-milaya [45]

he carbon cycle is the circulation and transformation of carbon back and forth between living things and the environment. Carbon is an element, something that cannot be broken down into a simpler substance. Other examples of elements are oxygen, nitrogen, calcium, iron, and hydrogen. Carbon compounds are present in living things like plants and animals and in nonliving things like rocks and soil. Carbon compounds can exist as solids (such as diamonds or coal), liquids (such as crude oil), or gases (such as carbon dioxide). Carbon is often referred to as the "building block of life" because living things are based on carbon and carbon compounds.

The Carbon CycleSource: NASAClick to enlarge

The amount of carbon on the earth and in Earth's atmosphere is fixed, but that fixed amount of carbon is dynamic, always changing into different carbon compounds and moving between living and nonliving things. Carbon is released to the atmosphere from what are called "carbon sources" and stored in plants, animals, rocks, and water in what are called "carbon sinks." This process occurs in a number of steps. In the first step, through photosynthesis (the process by which plants capture the sun's energy and use it to grow), plants take carbon dioxide out of the atmosphere and release oxygen. The carbon dioxide is converted into carbon compounds that make up the body of the plant, which are stored in both the aboveground parts of the plants (shoots and leaves), and the belowground parts (roots). In the next step, animals eat the plants, breath in the oxygen, and exhale carbon dioxide. The carbon dioxide created by animals is then available for plants to use in photosynthesis. Carbon stored in plants that are not eaten by animals eventually decomposes after the plants die, and is either released into the atmosphere or stored in the soil.

Large quantities of carbon can be released to the atmosphere thr

# difference between monocyclic &amp; polycyclic disease. ​
Triss [41]

Answer:

The monocyclic pathogen follows the black arrows to complete its cycle. Polycyclic pathogens follow the red arrows for the majority of the season and the black arrows at the end of the season. In order for a disease to develop, a pathogen must be present and successfully invade plant host tissues and cells.
