Because the structure of the enzyme matches that of the substrate, it can only catalyze certain types of reactions. A biomolecule called an enzyme speeds up a chemical reaction.
What do you mean by Enzyme ?Catalysts are substances that accelerate chemical reactions without acting as reactants. Enzymes are the catalysts for biological reactions that take place in living things. Although certain ribonucleic acid (RNA) molecules also function as enzymes, proteins make up the majority of enzymes.
The vital function of enzymes is to reduce the activation energy of a reaction, or the amount of energy required for the reaction to start. In order to facilitate the chemical bond-forming and bond-breaking processes, enzymes bind to reactant molecules and hold them in place.

What color is rare in nature as a pigment, most often occurring as a structural color?
Blue is extremely uncommon in nature, though. Blue flowers only appear on fewer than one in ten plants, and blue creatures are far rarer.
How come then?
As a result, both plants and animals must use optical illusions to appear blue. This is partly because there isn't really a true blue pigment or colour in nature. In the lapis lazuli substance, which is mostly mined in Afghanistan and gives the uncommon blue hue ultramarine, trisulfide ions are present, which are three sulphur atoms bound together inside a crystal lattice. One electron can be bound or released by these ions.

Which of these factors does cites fail to consider when determining which species to cover?.
The sustainability of the Ecosystem is the factor that CITES neglects to take into account when choosing which species to cover. A biological setting with several habitats that are capable of thriving and supporting itself independently is referred to as a sustainable ecosystem.
The biosphere can meet the needs of the current generation without compromising the ability of future generations to meet their own needs.
Sustainability is essential for many reasons, including Environmental Quality - Healthy communities require toxic-free environments, clean air, and natural resources. Growth - As UNTHSC's enrollment keeps expanding, we need additional space, energy, and water.
Thus, we can conclude that CITES fails to consider the sustainability of the ecosystem when deciding which species to include in its list of protected species.

what population control strategy has a big impact on population growth without infringing on people's rights to reproduce?
The population control strategy that greatly impacts population growth without infringing on people's rights to reproduce is replacement fertility practices by individuals.
The strategy or technique used to manage and maintain the types, locations, and numbers of people who populate the planet is known as population control. Over the course of a century, quality and status of life have drastically changed. We owe this to the world's inventive and cutting-edge technologies. Modern technology has several effects on the economy, including a decline in mortality and an increase in birth rate. One of the most hazardous issues currently plaguing the planet as a result of this is the population boom. India has seized its place among the most powerful nations. Everything has advanced to a new level, including the economics, status, and way of life. India has the largest population of this race. India now has 12 times as many people as it did when it gained freedom. Should this be stopped? Yes, but how? India was the first nation to implement a population policy, now known as the First Five Year Plan, in 1952 with the intention of containing the population expansion, but it was unsuccessful. The government later developed more practical strategies to manage the population boom by the 1970s. These included the Medical Termination of Pregnancy Act (1971), slogans for birth control on posters and bills, the marriage age requirement, contraception, etc.
Hence, population control strategy maintain population in equilibrium.

corona viruses are approximately 0.5micm in diameter how many coronaviruses could fir across a water froplet that was 1cm across
Number of corona virus that can be fitted into one water droplet is 39990
The volume of a sphere is the amount of space occupied inside the sphere. A sphere is defined as a three-dimensional round solid with all points on the sphere equidistant from the center. The fixed distance is called the radius of the sphere and the fixed point is called the center of the sphere.
Explanation:
1 mm is equals to 1 x 10-4 cm
Given, the diameter of corona virus is 0.5 mm i.e equals to 5 x 10-5 cm
Assuming corona virus is spherical in shape, volume of one corona virus is
Volume(c)=[tex]\frac{4}{3} \pi r^{3}[/tex]
Where, r is the radius of virus = diameter of virus/2
= 5 x 10-5 / 2 = 2.5 x 10-5
Putting value of r in above equation,
Volume(c)=[tex]\frac{4}{3} \pi (2.5*10^{-5}) ^{3}[/tex]
= 0.0001047 cm3
Now we have to calculate volume of one water droplet. We have diameter of water droplet is 1 cm . So volume will be
Volume(w)=[tex]\frac{4}{3} \pi (1) ^{3}[/tex]
= 4.187 cm3
Number of corona virus that can be fitted into one water droplet is Volume of one water droplet / volume of one corona virus = Volume (W) / Volume (C) = 4.187/ 0.0001047 = 39990.448 = 39990

T or F
The synaptic cleft is the name for the tiny space that exists between the membrane of the postsynaptic cell and the axon terminal of the presynaptic neuron. Thus this statement is true.
What is the synaptic cleft ?A synapse, or space where two neurons connect to one another, is called a synaptic cleft. Pre-synaptic neurons are attached to one side of it, and post-synaptic neurons are attached to the other. There is always an axon terminal on the presynaptic neuron.
Synaptic cleft refers to the area between two neurons where a neurotransmitter transmits an impulse. Presynaptic neurons and postsynaptic neurons are the two types of neurons that deliver and receive information, respectively.
These signals can also be modified through the synaptic cleft, such as by lengthening or shortening the signal's duration or adding more than one signal. The synaptic cleft's chemical makeup enables signal modulation, summarization, and a high degree of control rather than the straightforward on/off switch that is typical of electrical impulses.

D. it creates an increase in product of a reaction
Negative feedback helps to keep a variable within its regular range and lessens an overreaction.
How does unfavourable criticism work and what is it?
Negative feedback occurs when an output of a system, process, or mechanism is given back in a way that aims to reduce oscillations in the output, whether these oscillations are caused by changes in the input or other disturbances.
What possible repercussions could negative feedback have?
Because the feedback energy (voltage or current) is out of phase with the input signal when there is negative feedback, the input signal opposes the feedback energy. Negative feedback reduces the amplifier's gain. It also reduces distortion, noise, and instability. The bandwidth is increased while the input and output impedances are improved by this feedback.

what types of calculations can you do regardless of whether or not a question tells you that the population is in hwe for a given gene?
Regardless of whether we are in a situation subject to the population being in HWE or not, the genotype frequencies can be used to calculate the allele frequencies.
What is The Hardy-Weinberg Equation (HWE)?The Hardy-Weinberg equation states that the frequency at which a specific genotype occurs can be expressed as a ratio of the genotype in question to the total number of alleles in the population.
Algebraically, the equation is expressed as:
p² + 2pq + q² =1
The terms of this equation are defined as follows:
p = the frequency of the dominant allele in a population
q = the frequency of the recessive allele in a population
2pq = the frequency of the heterozygous dominant genotype
p² = the frequency of homozygous dominant genotype
q² = the frequency of homozygous recessive genotype
Because the set of all alleles in the population is made up of one part dominant alleles and one part recessive alleles, the sum of p and q will always equal 1.

the myelin sheath along an axon is not continuous. what are the gaps between schwann cells called?
The gaps or spaces in-between Schwann cells are referred to as nodes of Ranvier.
The nodes of Ranvier are a term used to describe each space between internodes in the myelin sheath. Positive sodium ions are prevalent in the nodes of Ranvier. The electrical signal or impulse bounces between nodes as it moves through the axon. The sodium ions refresh the electrical signal as it crosses the gap, allowing it to continue traveling without losing its charge or weakening in signal power.
Electrical transmission on nerve cells is delayed or halted when the myelin sheath is compromised. When the immune cells in your body mistake myelin for a foreign material, myelin might suffer harm. Your symptoms are based on where the myelin is damaged. Demyelination is the term for the loss of the myelin sheath.
