Plants and animals' bodily cells are eventually clones created by an one fertilized egg going through mitosis, or cell reproduction.
The term "clone," derived from the Greek klon, was first used in 1903 by plant physiologist Herbert J. Webber to describe the process of growing new plants from cuttings, bulbs, or buds. Howard Markel, a science historian, talks about how the phrase later evolved to apply to a variety of genetic alterations.Plants and animals' bodily cells are eventually clones created by an one fertilized egg going through mitosis, or cell reproduction. Every cell in clones' bodies has identical genetic information in the nucleus, which is where the chromosomes are located. Thus, the DNA and genes in the nucleus of cells from two clones are identical. The word "cloning" refers to a variety of procedures that may be used to create biological copies that are genetically identical to the original. A clone is a copy of a substance that shares the same genetic make-up as the original.

Pepsin, trypsin and chymotrypsin are substances that affect reaction rates, those can be defined as
Answer: Enzymes
Explanation:
Enzymes are those proteins which participate in a chemical reaction without being consumed in the reaction. These enzymes work as a catalyst which speed up the rate of the chemical reaction. The enzyme is responsible for converting the substrate into a product. Pepsin is an enzyme present in the stomach it is activated by hydrochloric acid it is a peptic enzyme which converts proteins into peptones, trypsin and chymotrypsin are the enzymes secreted by the pancreas and it is responsible for digestion of proteins.
which heats up faster
Water or air
Answer:
Air
Explanation:
Air.
Why? Because air has a much lower specific heat capacity (Heat capacity - Wikipedia) per unit mass than water. Also, air is dispersed as a gas so that in any given volume the mass of air that would fill it is only a fraction of the mass of water that would fill the same volume. Take these two factors into consideration and you see that the amount of energy it takes to raise the temperature of a volume of air by one degree is minuscule compared to the amount of energy it takes to heat the same volume of water by one degree.
The one thing that is more challenging about air is actually getting the energy into it. Water is densely packed, whereas air molecules are much more widely separated, so that presents a heat conductivity challenge. However, if we’re talking about equipment specialized for heating air (i.e. a fan forcing air over heated coils) versus equipment specialized for heating water (flat plate, coils, pumps or no pumps, whatever), energy added at the same rate to each will heat an equivalent volume of air to a greater extent (i.e. raising temperature more quickly) that it will water.

As a glacier moves across the land, it pushes soil and rocks in front of it and to the sides of it. What are the hills resulting from this soil called?
Answer: They are called Moraines
Explanation: A glacier is a large body of ice originating from land that constantly moves slowly over land. It occurs in almost all parts of the world and makes up about 3/4 of fresh water all over the world.
Glaciers constantly move on land and they do this under their own weight.
As a glacier moves across land, it pushes soil and rocks in front of it and to the sides of it.
The resulting hill formed as a result of this soil movement is called a Moraine.
A moraine is sometimes referred to as a glacial till. It is an accumulation of materials (usually soil and rock) left behind by a moving glacier.

Sensory nerves carry information to the CNS, and the motor nerves carry information away from the CNS. Therefore, the correct statement is option B.
What is central nervous system?The central nervous system (CNS) includes the brain and the spinal cord responsible for processing information received from peripheral nervous system (PNS) to generate appropriate responses. The brain is the most complex organ of the CNS, carries various functions, including sensation, perception, movement, etc.
Sensory nerves transmit information from sensory receptors, such as those in the skin, muscles, etc. to central nervous system (CNS) and sensory nerves are activated by various types of stimuli.
Motor nerves transmit signals from the CNS to muscles, and other effectors throughout the body. These signals are responsible for activation of muscle contractions, produce movements, and other responses.
Therefore, sensory and motor nerves both work together to perform physiological functions where sensory nerves carry information to the CNS, and the motor nerves carry information away from the CNS.

Answer:
absorb heat from the sun
Explanation:
Greenhouse gases are specific type of gases that possess the ability to trap and emit heat/thermal energy in the atmosphere. They are able to do this because of their structure. Examples of greenhouse gases are carbon dioxide (CO2), methane (CH4), chlorofluorocarbon (CFC) etc and are mostly produced via anthropogenic activities.
Greenhouse gases are therefore, produced both artificially (by burning fossil fuels) and naturally and functions to absorb heat from the atmospheric surroundings.

How do the sun and moon affect the tides?
Answer:
The Sun causes tides just like the Moon does, although they are somewhat smaller. When the earth, Moon, and Sun line up—which happens at times of full Moon or new Moon—the lunar and solar tides reinforce each other, leading to more extreme tides, called spring tides.

Select the statement that describes the major site where antiviral action is blocked by the protease inhibitors. Select one: a. The protease inhibitors block the ability of the human immunodeficiency virus from attaching and entering the cell membrane. b. The protease inhibitors block the uncoating process of the human immunodeficiency virus by binding to protease. c. The protease inhibitors block the nucleic acid synthesis of the human immunodeficiency virus. d. The protease inhibitors inhibit the late protein synthesis and processing of the human immunodeficiency virus.
Answer:
d. The protease inhibitors inhibit the late protein synthesis and processing of the human immunodeficiency virus.
Explanation:
Protease inhibitors are antiviral agents used to fight against pathogenic viruses such as retroviruses (e.g., human immunodeficiency virus, HIV) and RNA viruses (e.g., hepatitis C virus). Protease inhibitors can drastically reduce the viral load. Protease inhibitors may target 1-virus-encoded proteases which are responsible to produce functional proteins from polyprotein precursors and 2-processing structural proteins that are required for virus assembly. Some examples of protease inhibitors include, among others, ritonavir and indinavir, which are used in patients with HIV infection.
