Answer:

A. Earth's rotation

Explanation:

Earth rotates on its axis; [circulating] air deflected to the right in Northern Hemisphere, air deflected to the left in the Southern Hemisphere

> said deflection is called the Coriolis effect.

Coriolis Effect causes distinct pressure zones between equator and poles.

Why is "Which of the Great Lakes is the largest body of water?" a good scientific question

amm1812

It can be answered through an investigation.

Explanation:

The question ''Which of the Great Lakes is the largest body of water'' is a good scientific question because it is a question that can be answered through investigation. To answer this question, a scientist, or a person that has it as an interest simply needs to go on terrain and do the research, or can simply acquire data that is already collected. Through it, it can be determined which of the Great Lakes is the largest body of water, which is the second largest etc.

The five Great Lakes are:

Lake Superior
Lake Hudson
Lake Michigan
Lake Erie
Lake Ontario

There are five lakes that consist the Great Lakes, and all of them have formed in the same period and through the same process. The lakes all have glacial origin, and all of them have formed when the last Ice Age ended. The largest of the Great Lakes is Lake Superior, while the smallest is Lake Ontario.

Eddi Din [679]

Think where mitochondria are found in the greatest numbers - they are found (for example) in liver cells, kidney cells, muscle cells etc. These tissues carry out a lot of work and thus require lots of energy.

<span>Fat is a storage product that sits there until required but the thyroid does lots of work involved in metabolism and therefore requires plenty of energy.

This should help :)

Imagine that you attempted to recreate Mendel's work with garden peas. You began by crossing true breeding violet-flowered, tall

salantis [7]

Answer:

(a) 90

(b) 30

(d) 10

F2 data for stem length (tall:dwarf) is consistent with Mendel's law of segregation.

F2 data for stem length (tall:dwarf) and flower color (violet:white) is consistent with Mendel's law of independent assortment

Explanation:

The F2 phenotypes are supposed to be in 9:3:3:1 according to Mendelian law. The total number of F2 progeny is: 80 + 36 + 39 + 5 = 160

(a) Hence, the expected number of tall, violet plants will be:

9/16 x 160 = 90

(b) Expected number of tall, white plants will be:

3/16 x 160 = 30

(d) Expected number of dwarf, white plants will be:

1/16 x 160 = 10.

Total number of tall F2 plants = 80 + 36 = 116

Total number of dwarf F2 plants = 39 + 5 = 44

Expected ratio of tall:dwarf plants according to Mendel = 3:1

Expected number of tall plants = 3/4 x 160 = 120

Expected number of dwarf plants = 1/4 x 160 = 40

Chi square $X^2$

= $\frac{(observed frequency - expected frequency)^2}{expected frequency}$

$X^2$ for tall = $\frac{(116 - 120)^2}{120}$

= 0.1333

$X^2$ for dwarf = $\frac{(44 - 40)^2}{40}$

= 0.40

Total $X^2$ = 0.1333 + 0.4

0.5333

Degree of freedom = n - 1

2 - 1 = 1

Tabulated $X^2$ (α = 0.05) = 3.841

Since the tabulated $X^2$ is more than the calculated $X^2$ , the hypothesis that the F2 data for stem length (tall:dwarf) is consistent with Mendel's law of segregation is accepted.

Observed Expected $X^2$

tall, violet flowers 80 90 $\frac{(80-90)^2}{90} = 1.11$

tall, white flowers 36 30 $\frac{(36-30)^2}{30} = 1.2$

dwarf, violet flowers 39 30 $\frac{(39-30)^2}{30} = 2.7$

dwarf, white flowers 5 10 $\frac{(5-10)^2}{10} = 2.5$

Total 160 160 7.51

Degree of freedom = 4 - 1 = 3

Tabulated $X^2$ (α = 0.05) = 7.815

The tabulated $X^2$ value is more than the calculated $X^2$ value. Hence, F2 data for stem length (tall:dwarf) and flower color (violet:white) is consistent with Mendel's law of independent assortment.

How many generations are represented in the pedigree above? *

pantera1 [17]

Answer:

A basic pedigree usually includes three generations—the consultand's first-degree relatives (parents, children, siblings) and second-degree relatives (half siblings, grandparents, aunts and uncles, grandchildren). Third-degree relatives, particularly cousins, are often included, if only to note that they "exist."
