kondaur [170]3 years ago
5 0

Answer:

The correct answer is option D

The vertical, central axis of the human body is formed by the axial skeleton. It consists of 80 bones which include a skull, neck, chest, and back. It includes 22 bones of the skull, 6 bones of middle ears, 1 hyoid bone, 26 bones in the vertebral column, and 1 sternum, and 12 pairs or 24 ribs.  

Together with the appendicular skeleton (126 bones), it forms the complete skeleton.

The pedigree traces red-green color blindness. Lisa and Monica are half-filled circles. Sam, Bella, Joshua, and Tim are filled-i
lyudmila [28]

Answer:

Sam, Tim, Bella, and Joshua

Explanation:

The correct answer would be <em>Sam, Tim, Bella, and Joshua</em>.

<u>The human pedigree is a pictorial representation of a family tree that depicts how a particular trait is inherited across different generations.</u>

In the human pedigree, those phenotypically affected for the trait in question are represented by filled-in shapes, with circles representing females and squares representing males. Half-filled shapes represent heterozygosity or carriers of the trait.

<em>Sam, Tim, Bella, and Joshua were represented by filled-in shapes in the illustrated pedigree. Hence, they are affected for red-green color blindness. </em>

The p wave of the electrocardiogram is a signal from
Ratling [72]

The P wave of the electrocardiogram is considered as a signal from the DEPOLARIZATION of the atria in the heart. This depolarization drives the contraction of the atrial musculature.

An electrocardiogram (ECG) is a device that records the electrical activity of the heart. This record can then be used to diagnose different heart conditions.

The P waves occur when the sinoatrial node generates an action potential which is capable of depolarizing the atria.

This depolarization is then followed by atrial contraction and an increase of the pressure in the atria.

The concentration of N2 in blood at 37 °C (body temperature) and atmospheric pressure (partial pressure of N2 = 0.80 atm) is 0.0
devlian [24]

Answer:

volume  = 0.285 L

Explanation:

Henry constant is given as

Henry constant  =  \frac{C}{P}

Where C  is concentration

P is atmospheric pressure

Henry\ constant = \frac{0.00056}{0.80} = 0.0007 M/atm

when atmospheric pressure 4 atm

solubility = K_H\times P

              = 0.0007 \times 4 = 0.0028 M

In 5 litere blood , moles of N_2 = Molarity \times volume

                                                     = 0.0028 \times 5 = 0.014

At surface moles  = 0.0056 \times 5 = 0.0028

Moles of N_2 release = 0.014 - 0.0028 = 0.0112

Mass of N_2 = 0.0112 \times 28 = 0.314 g

T = 37 + 273 = 310 K

VOLUME = \frac{nRT}{P}

= \frac{0.0112\times 0.0821\times 310}{1}

volume  = 0.285 L

Please HELP////2. A couple are both phenotypically normal, but their son suffers from hemophilia, a sex-linked recessive disorde
katrin [286]

Answer:

1/4 suffer from hemophilia

1/4 are heterozygous

Explanation:

So since they are normal but their son isn't it is assumed that the mom is the carrier since the dad has to be X^HY

X^HY x  X^HX^h

Set up a pedigree

X^HX^H X^HX^h

X^HY     X^hY

1/4 suffer from hemophilia (X^h)

1/4 are heterozygous (X^HX^h)
