Answer:

The correct answer is: brachial plexus.

Explanation:

The brachial plexus is a net that is made of cervical nerves (more specifically, by the anterior rami of C5, C6, C7, C8 and T1) and extends from the cervicoaxillary canal to the armpit.

The nerves that form from the brachial plexus are both motor and sensory fibers that will provide innervation to the <u>chest, the shoulder, the arm, the forearm, and the hand.</u>

Answer:

Brachial plexus

Explanation:

Brachial plexus is a plexus of nerves that travels through the axillary region.

It is formed by ventral rami of spinal nerves C5-T1.

Five ventral rami forms roots/trunks that separate into divisions that then form cords that give rise to branches.Mojor nerves include Axillay, radial , musculocutaneous, Ulnar  , median.

In the axilla it is placed lateral to the 1st part of axillary artery, it surrounds the second part of axillary artery, one cord lying medial to it, one lateral to it, and one behind it, at the lower part of axilla it gives off its terminal branches to the upper limb.

Hence, The plexus that travels through the axillary region is the brachial plexus.

Arte-miy333 [17]

Answer:

Man encourages his sister to see a genetic counselor in order to find out that she has the genetic disease or not.

Explanation:

Cystic fibrosis is genetic disease that can transfer from parents to their offspring. This is a very dangerous disease which decrease the life span of patient and the patient die in early stages of life. The man with Cystic fibrosis disease encourage his sister to go to the genetic counselor to find out the presence of disease in her blood because she is planning a baby and we know that this is a hereditary disease so if she has this disease it will transfer to her child.

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

Porque un grupo de celulas pequeñas ayudarian a un organismo a mantener la homeostasis mejor que una celula grande?
NeX [460]

Answer:  

Una parte fundamental de la homeostasis es la transferencia y la ingesta de moléculas (sea necesario o no). Es importante que la célula pueda llevar los nutrientes necesarios inmediatamente donde los necesita y poder deshacerse de los subproductos dañinos del proceso celular. Es igualmente importante poder regular la concentración de agua. Las células más pequeñas tienen una superficie más grande en relación con su volumen (su superficie se escala con R ^ 2 mientras que su volumen con R ^ 3 donde R es el radio de una célula) y, por lo tanto, los intercambios a lo largo de la membrana celular se ven favorecidos en comparación con las células más grandes que necesitan muchos intercambios pero tienen proporcionalmente menos área de membranas. Si bien A no es necesariamente cierto, C es definitivamente cierto y, por lo tanto, la respuesta correcta.
