Answer:

b. hormones

Explanation:

"The endocrine system is made up of glands that make hormones. Hormones are the body's chemical messengers. They carry information and instructions from one set of cells to another"

Answer:

b have a good day

Explanation:

Answer:

The genotypic frequency = 1:1

The phenotypic frequency = 1:1

Explanation:

Given that:

The allele → R = Red beetles

The allele → B = Blue beetles

Since the gene color shows a codominant allele

The Red Beetle = RR

The blue beetles will be = BB

The heterozygous beetle will be = RB

∴

The punnet square showing the crossing of RB × RR is:

                R                   B

R                RR               RB

R                RR               RB

The result shows that we have two red beetles and two heterozygous beetles.

Hence;

The genotypic frequency = 1:1

The phenotypic frequency = 1:1

Answer:

B

Explanation:

In asexual reproduction, the offspring has identical genes/traits to the one of its parent.

In sexual reproduction, there's a combination of the genes/traits from both parents.

Answer:

C ender is released

Explanation:

the energy stored in the phosphate bonds hold the energy, when the bond breaks the energy stored is released

Answer: C

Explanation:

Answer:

Damage to interneurons.

Explanation:

The main cause of this situation is the damage occurs to the interneurons which is responsible for sending of instructions. The motor neurons can't receive the instruction from the central nervous system which results no movement of muscles. There must be damaged occur to interneurons because these neurons are responsible for sending instructions from central nervous system so if the information can be passed to the motor neurons so no movement occurs in the muscles.

Answer: I think B

Explanation:

In the logistic growth model, as a population approaches the carrying capacity, the growth rate of the population will slow down to zero. Thus, the correct option is D.

The logistic growth model is a parameter which represents the rate at which the population would grow if it were unencumbered by the environmental degradation. A second parameter, that is K, represents the carrying capacity of the system of species which are being studied.

In logistic growth, a population's per capita growth rate gets smaller and smaller as the population size when it approaches a maximum imposed by the limited resources in the environment, known as the carrying capacity (K). Exponential growth model produces a J-shaped curve, while logistic growth produces an S-shaped curve.

Therefore, the correct option is D.

Answer:    

Enters through the gills and tubed feet.

Explanation:

The oxygen obtained by a Purple Sea Urchin is dissolved in water.  Oxygen enters through the gills and tubed feet. When the oxygen level is low in a Purple Sea Urchin, muscles associated with Aristotle's Lantern pump fluid through the body (through the canals).

Any Questions?

Oxygen enters the sea urchin's system through the respiratory system, which is through the water vascular system, as the echinoderms have a significant type of system that helps them take the oxygen from the water.

The water vascular system is seen in the phylum of the echinodermata, which is essentially a network of canals and tube feet that run throughout the urchin's body, and the tube feet are helpful for the attachment to the surface and for the respiration. When the tube feet are extended, oxygen from the water diffuses across the walls of the tube feet and into the urchin's body, while carbon dioxide is released into the water.

Hence, oxygen enters the sea urchin's system through the respiratory system, which is through the water vascular system, as the echinoderms have a significant type of system that helps them take the oxygen from the water.
