Give a reason why Neurotransmitters are broken down by an enzyme just after passing an impulse from one neuron to the other????
DerKrebs [107]

Neurotransmitters are broken down by enzymes in order to avoid over-stimulation of a neuron and to allow for the transmission of impulse another impulse by the neurons.

<h3>What are neurotransmitters?</h3>

Neurotransmitters are chemical substances which are released at neuronal ends and which help transmit sction potential from one neuron to another.

After the transmission of impulse between the neurons, neurotransmitters ate broken down by enzymes.

Neurotransmitters are broken down by enzymes in order to avoid over-stimulation of a neuron and to allow for the transmission of impulse another impulse by the neurons.

Ralph has type B blood and his wife Rachel has type A blood. They are very shocked to hear that their baby has type O blood, and
Cerrena [4.2K]

Answer:

1. The parents genotypes could have been BO and AO

2. wire-hair

Explanation:

There are four possible blood types which are type A, B, AB, O. blood group is the classification of blood based on the presence or the absence of inherited antigenic substances on the surface of the red blood cells. They have hereditary basis and also rely on a series of alternative genes sometimes used in solving dispute of parental heritage. With the four possible blood groups, there are six possible genotypes and these are:

Blood type               possible genotypes

Type A                         AA, AO

Type B                         BB, BO

Type AB                           AB

Type O                              OO

Thus, for parents with blood type B and A to give birth to a child with blood type O, it means their genotype could have been both BO and AO  for them to be able to produce a child with OO. a cross between these two could give rise to OO.

Question 2

Wire hair is dominant (S) to smooth (s), thus wire hair could be in the homozygous (SS) and heterozygous form (Ss) and the smooth hair can only be expressed in the homozygous recessive form (ss).

thus, in a cross between homozygous wire haired and smooth haired, we will have:

homozygous wire haired            homozygous smooth haired

P gen              SS                x               ss

F1 gen.                                Ss

phenotype:                     wire haired

Complete the flowchart to identify the process by which blue-light photoreceptors and auxin control phototropism in plants.
DaniilM [7]
In plant seeds, the photoreceptor phytochrome is responsible for the process termed photomorphogenesis<span>. This occurs when a seed initially situated in an environment of complete darkness is exposed to light. A brief exposure to electromagnetic radiation, particularly that whose wavelength is within the red and far-red lights, results in the activation of the photorecepter phytochrome within the seed. This in turn sends a signal through the signal transduction pathway into the nucleus, and triggers hundreds of genes responsible for growth and development</span>

A genotype is controlled by the sex cells combining to form an organism. True or False
myrzilka [38]

True

A genotype is the combination of genes in its DNA of the organism that determines its traits

Explanation:

Gametes from parents contribute different alleles of genes to their offspring. This why gametes carry only one copy of genetic material of the organism. They later fuse to form a zygote with a full genetic copy and capable of developing into an full organism.

Depending on which kind of alleles the parents pass down to the offspring will determine the offspring's genotype. The genotype of the offspring will, on the other hand, affect its phenotype which is the outward characteristic. An example is the sickle cell trait. If both gametes from the parents contribute the recessive alleles of the gene, then the offspring will be homozygous recessive for sickle cell genotype and this will show in the phenotype pf the person who will have sickle cell shaped blood cells.
