A rise in CALCIUM released from the sarcoplasmic reticulum allows actin to bind to myosin and cause a contraction, which requires ATP energy. ATP is the energy coin of the cell.
Adenosine triphosphate (ATP) is the energy coin that cells use to carry out many metabolic reactions (e.g., reproduction, motion, differentiation, etc).
The sarcoplasmic reticulum is an organelle located inside muscle cells similar to the smooth endoplasmic reticulum.
This organelle (sarcoplasmic reticulum) acts to store calcium which is required during muscle contraction.

Which codon is the code for the amino acid valine (Val)?
Answer: A. GUC
Explanation:
Looking at the codon chart, we see that on the lower left corner (where first base in codon is G) the whole section matches to amino acid valine. Therefore, GUU, GUC, GUA, and GUG are all correct answers, but since GUC is the only correct choice in the four choices given, GUC is the answer to this question.

Why are Flowers considered as the reproductive part of a plant
Answer:
because it houses the male and female parts of the plant which produce the male and female gametes
Answer:
Flowers are called reproductive structures of plant as they contain both male and female parts which reproduces to produce pollen grains and eggs. Each of them fertilizers and produces embryo which eventually produces new plant.

Carbon is found in different forms on the Earth. It is found as carbon dioxide in the atmosphere, as carbonate and bicarbonate salts in various minerals, as well as it occurs in the elemental form of diamonds and graphite. All biotic factors are based on carbon-containing molecules like carbohydrates, proteins, fats, nucleic acids and vitamins. Carbon is incorporated into life-forms through photosynthesis which is performed in the presence of sunlight by all life-forms that contain chlorophyll. Photosynthesis converts CO2 from the atmosphere or dissolved in water into glucose molecules. These molecules are either converted into other substances or used to provide energy for the synthesis of other biologically important molecules.
The use of glucose to provide energy to living things involved the process of respiration in which oxygen may or may not be used to convert glucose back into CO2. This CO2 goes back into the atmosphere again. The process of combustion also adds to the level of carbon dioxide in the atmosphere. This percentage is said to have increased when human beings started cutting down trees, burning fossil fuels, etc. on a very large scale. Thus, carbon is cycled repeatedly through different forms by the various physical and biological activities and this cycle is therefore called carbon cycle.
Hope you could get an idea from here.

Carbon cycle is a biogeochemical cycle in which the carbon atom continously moves in the atmosphere through different forms and processes.
What is Carbon cycle?The carbon cycle is the biogeochemical cycle which describes the process through which carbon atoms continually travel from the atmosphere to back to the Earth and then back into the atmosphere. This cycle goes on repeatedly. Since our planet and its atmosphere forms a closed environment, the amount of carbon in this system does not change, it only transforms from one form to another.
The processes which takes place in carbon cycle include photosynthesis, decomposition, respiration, and combustion. Carbon cycles from the atmosphere into the plants and living things. For example, carbon is a pollutant in the atmosphere which is present as carbon dioxide gas.
Carbon moves from the plants and animals to soil. When the plants and animals die, their bodies, wood, and leaves decays which being carbon into the ground. Some of this carbon is buried and become fossil fuels in millions of years. Carbon moves from living things to the atmosphere through respiration in which they inhale oxygen gas and exhale carbon dioxide gas.

HIV is unique because it copies the information for reproduction from RNA back into DNA.
Explanation:
True. it is a virus and that's how viruses reproduce.
HIV is a virus which is unique because it copies the information for reproduction from RNA back into DNA, the statement is true.
What is virus ?A virus is a nonliving thing which is a connecting link between living and nonliving organism, depend on living host cell for their survival.
virus contain a chain of nucleic acids (DNA or RNA) which use different parts of the cellular machinery to reproduce, and releases the replicated nucleic acid chains
A virus has a protein coat or protein envelope allows the virus to survive between hosts act as a protective covering, do not have cells and lack a cell wall .
The protein coating is called as the capsid, genetic element present and is characterized by the evolution of the virus and the host.

Path-breaking medical procedures have begun to pay attention to how microscopic entities aid or hinder bodily health. For example, fecal transplants have helped cure chronic digestive ailments of people who have suffered for years. These new procedures treat the body not as a separate, contained biological entity but as a complex: ___________
a. biomedicine.
b. anthrobiotic environment.
c. personal biosystem.
d. human microbiome.
Human microbiome that is as complex entity of all the microorganism found in the entire body structure of all living organism and the exact location where they are found.
Fecal transplants is idea for replenishing of good bacteria in the body due to resistance from prolong use of antibiotics. It is specifically for treatment of resistance of antibiotic therapy due C. difficile colitis.
In patient above 65, infected with C. difficile colitis and with resistance to antibiotic especially oral vancomycin, fecal transplant is applied to effectively cure this.
The transplant is conducted through the Colonoscopy. Where the fecal is discharge into the colon as the Colonoscope is withdrawal from the colon
.
Since natural good bacteria are present in fecal and have no effect on the good bacteria in the body, this procedure increased the total number of bacterial(microbiota),by stabilizing the the microbiome and curing the patients.

Explain why the accidental and intentional introduction of new pests is likely to be an ongoing problem for future agriculture, and include possible approaches to solving the problem.
The introduction of pests in a new geographic region may have devastating consequences on crop yields. Invasive pest species often don't have natural predators or exhibit higher adaptive fitness.
Invasive species represent an important subject of concern in agriculture because they have the potential to drastically reduce crop yields.
Generally, invasive pest species don't have natural predators or exhibit higher adaptive fitness compared to well-established natural pest species.
In consequence, these species (invasive species) may cause considerable harm to crops.

Which statement is true about the energy level of solids?
A.) Solids have more energy than water
B.) Solids have more energy than plasma
C.) Solids have the most amount of energy
D.) Solids have the least amount of energy
Answer:
The answer is D.) Solids have the least amount of energy
Explanation:
Because in a solid, particles are packed tightly together so they don't move much. The electrons of each atom are constantly in motion, so the atoms have a small vibration, but they are fixed in their position. Because of this, particles in a solid have very low kinetic energy.
