How did wegner use climate evidence to support his hypothesis​

Biology

Novay_Z [31]3 years ago
5 0

Explanation:

Wegener used evidence of climate change to support his hypothesis. As a continent moves toward the equator, its climate becomes warmer. As a continent moves toward the poles, its climate becomes colder. But the continent carries with it the fossils and rocks that formed at its previous locations.

In humans, dimples (D) are dominant over no dimples (d). Curly hair (A) is dominant over
jeyben [28]

Answer:

1. ddaa

2. DdAa

3. One from each parent

4. False

5. 0.25

6. 0.25

7. 0.25

8. 0.5

Explanation:

The remaining part of the question is  

1. What is Jane's genotype?  

2. What is Paul’s genotype?  

3. Where did Jane get her gene for curly hair? From her mother or father?  

4. True or False: Jane's mother was heterozygous for curly hair?

5. What fraction of Paul and Jane's children should have curly hair and dimples?  

6. What fraction of their children would have straight hair and no dimples?  

7. What fraction should have dimples but not curly hair?  

8. What is the probability of getting any offspring with dimples

Solution

1. Genotype of Jane's mother -ddaa

2. Genotype of Paul (heterozygous for dimples and curly hair) – DdAa

3. One “a” gene from mother (whose genotype for hair was aa) and second “a”gene from father (whose genotype was  Aa)

4. False.  She was having straight hair

5. Offspring of  Paul and Jane  

DdAa (4), Ddaa (4), ddAa(4) and ddaa (4)

4 out of 16 offspring will have curly hair and dimples = 0.25

6. ddaa, 4/16 = 0.25

7. Ddaa , 4/16 = 0.25

8. Ddaa, DdAa, 8/16 = 0.5

Explain how a rise in carbon dioxide concentration in the atmosphere can decrease biodiversity.​
Zolol [24]
Elevated carbon dioxide levels may mitigate losses of biodiversity from nitrogen pollution. ... Rising levels of carbon dioxide may overheat the planet and cause other environmental problems, but fears that rising carbon dioxide levels could directly reduce plant biodiversity can be allayed, according to a new study.

Skin stem cell at the g2 checkpoint of the cell cycle contains 14 chromosomes but twice the amount of dna as one in the g1 stage
kotegsom [21]
The diploid number for the specie is 14 chromosomes. Diploid means the paired chromosomes as opposed to haploid which is 7 chromosomes.
G2 or gap 2 phase of the interphase is where DNA synthesis occurs and where the chromosomes are replicated to generate sister chromatids.

What is meant by a phenotype ratio in a Punnett square? (1 point)
Lemur [1.5K]

Given the nature of a punnet square, we can conclude that the ratio in question refers to the combination of genotypes present in the square.

A punnet square is a diagram used to attempt to predict the <u>genetic composition </u>for the <u>offspring</u> of certain parents, that is the genotype for this specific cross. This is done by creating a square in the form of a grid and placing the genotypes of the parents on the outside of this then crossing them along the inside.

This diagram provides us with the probability of each genotype outcome. This is known as the phenotype ratio. The phenotypic ratio is the amount of times a specific outcome, such as a certain pair of alleles appears in the predicted genotypes of any of the <u>offspring pertaining </u>to this <u>cross</u>.
