An effect of a heterotropic activator on a sigmoidal kinetic plot of V₀ versus [S] is a shift to the left by the curve.

An enzyme refers to a biological catalyst that speeds up the rate of a chemical reaction, especially by lowering the activation energy of its chemical reactants.

In Science, a heterotropic activator is a regulatory molecule which serves as an activator of the enzyme. Thus, an effect of a heterotropic activator on a sigmoidal kinetic plot of V₀ versus [S] would be a shift to the left by the curve.

Answer:

So, the correct answer is 'Cells wall is rigid and does not get overstretched'

The phenotypic ratio of their offspring would be 1/4 each for black eyes/green skin, black eyes/white skin, orange eyes/green skin, and orange eyes/white skin respectively.

The male would be heterozygous since he has a parent that is homzygous recessive.

Assuming that eye color is A/a and skin color is B/b.

The genotype of the male would be: AaBb

The genotype of the female would be: aabb

                   AaBb    x    aabb

Progeny

A_B_ = Black eyes, green skin = 1/4

aaB_ = orange eyes, green skin = 1/4

A_abb = black eyes, white skin = 1/4

aabb = 1orange eyes, white skin = /4

The laws of conservation of mass applies to ecology because the transfer of nutrients from organisms to the ground results in excess energy not disappearing

Answer: The law of conservation of mass states that the total amount of mass remains constant in a system. In ecology, this means that when an organism is eaten, its mass is conserved. Some of the organism’s mass is used to make new proteins, and some of it is passed as waste in the form of urine or feces. The rest is converted directly into energy. This energy helps the consumer to move and grow, and it helps it to build and repair new tissue.

The probability that their next child will have polydactyly is 0.75

Polydactyly may be characterized as a circumstance in which an individual has more fingers or toes as compared to normal.

In humans, it occurs due to the homozygous mutants for a HOXD13, and due to which digits are joined and a condition known as Polysyndactyly occurs.

If both parents carry the genotype heterozygous for Polydactyly, i.e. Pp, the resultant offspring will have the genotypes PP, Pp, Pp, and pp. In which pp is normal, while all the three are affected due to the expression of dominant allele causing Polydactyly.

Now, according to the question, only one of the offspring possess the genotype of pp, hence the probability of their next child will have polydactyly is [tex]\frac{3}{4}[/tex] = 0.75.

Therefore, the probability that their next child will have polydactyly is 0.75.

a. reduces immunity to diseases

The effect increasing UVR has on animals is reducing immunity to diseases.

A body could be heated to an incandescent temperature to generate UV radiation, which seems to be the case with solar UV, or an electric current would be sent through a gas, typically vaporized mercury, to generate UV radiation.

A disease would be a specific aberrant state that adversely affects an organism's structure as well as function on the whole or in part, and which could be not immediately brought on by any external trauma.

The sympathetic and parasympathetic are responsible for the body's spontaneous actions, such as breathing, heartbeat, digestion, body temperature control.

The sympathetic nervous system acts in an opposite way to the parasympathetic one, preparing the organism to react in situations of fear, stress and excitement, adapting the functioning of several internal systems to a high state of readiness.

In this case, the Sympathetic nervous system also controls body functions that are rarely conscious and parasympathetic nervous system the part of the autonomic nervous system responsible for stimulating actions that allow the body to respond to calm.

Environmental factors can influence natural selection because they can increase or decrease and what can they increase or decrease in the amount of genetic variation in a population.

Populations of living things adapt and change through a process called natural selection. A population's members are naturally varied, which means that they are all distinctive in some ways. Because of this variety, some people have characteristics that suit their surroundings more than others.

Four requirements must be met for natural selection to take place: reproduction, inheritance, variety in physical traits, and variation in the number of children produced by each person.

Reproduction:

A population must procreate to produce a new generation in order for natural selection to affect it. Over many generations, people who have the characteristics that are most compatible with their environment tend to breed more than people who don't.

Heredity:

Since the genes of the parents combine to form the DNA of their offspring, heredity and reproduction go hand in hand. Natural selection must operate if parents with favourable qualities pass those traits on to their kids.

Variation in Characteristics:

Only when individuals within a community differ in their personal features can natural selection take place. For instance, different people must have varied colors in order to research natural selection on color within a population. There wouldn't be any traits for nature to "select" over others in the absence of variety in traits.

Fitness Variation:

Compared to its popular notion, fitness has a more technical meaning. Fitness in the context of evolution refers to an organism's capacity for maximum survival and reproduction. Natural selection cannot take place in a population unless its individuals have varying levels of fitness. Some people must have characteristics that make it easier for them to survive and procreate more frequently than others. Otherwise, natural selection cannot act to increase the number of people with advantageous features and decrease the number of people with undesirable qualities.
