This diagram shows that embryos of certain species develop almost identically in the earliest stages of embryonic development. T

hese physical similarities indicate that there are also genetic similarities among these organisms. The physical and genetic embryological similarities among these organisms suggest that they A. descended from a common ancestor. B. have multiple vestigial organs in common. C. are members of the same genus. D. hunt and breed in similar habitats.

The correct option is A.
The observation that the embryos of certain species have physical and genetical similarities in the earliest stages of embryonic development shows that individual development of an organism shows its revolutionary history and this is taken as an evidence of common ancestry. Scientists takes this observation to mean that all life on earth developed from a single ancestor.<span />

Novay_Z [31]

Answer:

In sample A,  

The percentage of thymine or T is 20.5 %. A = T, so the percentage of A will also be 20.5 %.  

Thus, A + T = 20.5 + 20.5 = 41 %

Therefore, G + C = 100 - 41 = 59 %

So, G = 59 /2 = 29.5 %

Also. G = C = 29.5 %

In sample B,  

The percentage of Thymine or T is 30.7 %. As A = T, so A will also be 30.7 %.  

Thus, A + T = 30.7 + 30.7 = 61.4 %

Also, G + C = 100 - 61.4 = 38.6 %

So, G = 38.6 / 2 = 19.3 %

Therefore, C will also be 19.3 %. As GC content is more found in the sample A, that is, 59 %. Hence, the sample A will possess the higher temperature to denature in comparison to B.

How much protein should Sarah add to her diet if she gets pregnant?Sarah's protein requirements during pregnancy would be higher
GenaCL600 [577]

Answer:

Sarah should add 19 grams of protein to her diet if she gets pregnant.

Explanation:

Daily protein requirements = body weight in x conversion factor

Pregnant women= 1.1g/kg prepregnancy body weight

Sarah's prepregnancy weight= 132 pound

Sarah should add about 19 grams of protein to her diet to account for the higher protein requirements of pregnancy. That’s only about 1 cup of Greek yogurt. Pregnancy  might be the time to switch to these “twice the protein” products.

When the antibiotic valinomycin is added to actively respiring mitchondria, several things happen: the yield of ATP decreases, t
ryzh [129]

Answer:

The correct answer will be- Uncoupler (ionophore)

Explanation:

Valinomycin is a antibiotic which uncouples the process of ATP synthesis and the electron transport chain.

The valinomycin decreases the yield of ATP synthesis by allowing the inward movement of the K⁺ ions across the inner mitochondrial membrane. This inward movement disrupts the proton gradient which decreases the yield of the ATP synthesis.

Also, the consumption of oxygen increases in the electron transport chain which generates heat during ATP synthesis.

Thus, Uncoupler (ionophore) is the correct answer.
