An air mass that originates in the Pacific ocean, west of Brazil, is most likely WARM AND WET.

A. warm and wet

Explanation:

The pacific ocean has the tropical maritime air mass so it is warm and wet. they affect the United States originate over the Caribbean sea, Mexico, pacific and the western Brazil.

So the air masses in the pacific ocean, western Brazil are wet and warm.the air masses have the fairly uniform temperature and the moisture content in the horizontal direction.

Air masses are characterized by their temperature and the humidity properties. The air mass where the originate is based on the surface properties.

Answer;

-Midsagittal cut

A neuroscientist cuts a brain in half, along the division between the hemispheres. this cut is referred to as a midsagittal cut.

Explanation;

The midsagittal plane divides the human body into equal left and right halves. It is used to describe the sagittal plane as it bisects the body vertically through the midline marked by the navel, dividing the body exactly in left and right side.

-If divided along this plane, the deepest structures of the human body will be visible. Starting with the most superior portion of the body, visible would be the brain. Cutting along the midsagittal plane, the structures of the brain would be exposed including the pineal body, the corpus callosum, thalamus, midbarin, pons, medulla oblangata, hypothalamus, and the arbor vitae of the cerebellum.

In humans there is a dominant allele (A) for the absence of moles; while the recessive allele (a) results in the presence of mol

Art [367]

Answer:

a. $(p + q)^7$ = $p^7q^0+7p^6q+21p^5q^2+35p^4q^3+35p^3q^4+21p^2q^5+7pq^6+p^0q^7$

b. i. 0.75

ii. 0.000061

iii. 0.012

iv. 0.17

c. 0.67

Explanation:

a. The expansion of the binomial (p + q)7 would be such that:

$(p + q)^7$ = $p^7q^0+7p^6q+21p^5q^2+35p^4q^3+35p^3q^4+21p^2q^5+7pq^6+p^0q^7$

b. Both couples are heterozygous:

Aa x Aa

AA Aa Aa aa

Since A is dominant over a,

probability of having mole (aa) = 1/4

probability of not having moles = 3/4

Therefore, the probability of the first child not having moles = 3/4 or 0.75

ii. Let the probability of not having mole = p and the probability of having mole = q. From the binomial expansion:

$(p + q)^7$ = $p^7q^0+7p^6q+21p^5q^2+35p^4q^3+35p^3q^4+21p^2q^5+7pq^6+p^0q^7$

Probability that all of the children will have moles = $p^0q^7$

since p = 3/4 and q = 1/4

$p^0q^7$ = $(3/4)^0(1/4)^7$ = 0.000061

iii. Probability that the first two children will have no moles and the last five will have moles = $21p^2q5$

= $21(3/4)^2(1/4)^5$

= 0.012

iv. Probability that 4 will have no moles and 3 will have moles out of the 7 children = $35p^4q^3$

= $35(3/4)^4(1/4)^3$

= 0.17

c. Probability that the child born without moles is a carrier of the a-allele = probability of heterozygous.

From the cross in (b), the genotypes of those born without moles are AA and 2Aa. Therefore, the probability of not having moles and be Aa is:

= 2/3 or 0.67

Based on your observations why is magnification important to the study of life science

ValentinkaMS [17]

In multicellular organisms, several cells of one particular kind interconnect with each other and perform shared functions to form tissues (for example, muscle tissue, connective tissue, and nervous tissue), several tissues combine to form an organ (for example, stomach, heart, or brain), and several organs make up an organ system (such as the digestive system, circulatory system, or nervous system). Several systems functioning together form an organism (such as an elephant, for example).
