<span>If you examine a rock sample and observe fossils in it, the type of rock the sample represent in C - sedimentary. Igneous rock is  a melted and cooled rock and there are no remains of any kind of fossils. Still, can be found some fossils traces in some metamorphic rocks with the lowest grade of metamorphism but those are very very rare. 
the answer is C, sedimentary </span>

Sedimentary rocks are the only ones that have the ability to preserve a fossil.

Both the full body plate type and the half body plate trait are also present in an ocean near the lake. Where would you expect a
meriva

Answer:

In the ocean

Explanation:

Ecological divergence leads to selection of essential traits against migrants and hybrid species. The full body plate type traits requires attention for occurrence  in an environment which is free from issues such as resource limitation or predator attacks. In vast ocean spaces , resources are not a limiting factor in ocean and also there is no risk of predators as there is huge chunk of space, thus, full body plate type will occur in higher number in the ocean.

hope it helps you..

Which statement is NOT part of the Mitchell chemiosmotic hypothesis? High‑energy phosphorylated intermediates that serve as phos
gogolik [260]

Answer:

High-energy phosphorylated intermediates that serve as phosphate donors to ADP are generated as a result of electron-transfer reactions.

Explanation:

Peter Mitchell proposed Chemiosmotic hypothesis which state that the driving of the synthesis of ATP is accomplished by a proton-motive force. He propose that whenever electron is moved along the electron transfer chain then proton will be moved accross the inner part of mitochondria membrane. As a result of this there would be increase in PH of the mitochondria matrix and reduced PH of the intermembrane space.

Some Evidence about Chemiosmotic hypothesis hypothesis;

1)transportation of electron brings about the generatation of a proton gradient. there is difference in the PH on the outside and inside the mitochondria.

2)To synthesis ATP, a proton gradient is required only and other means by which PH gradient is generated

Therefore,High-energy phosphorylated intermediates that serve as phosphate donors to ADP are generated as a result of electron-transfer reactions is not Micheal Mitchell statement.

Researchers believe that in a fish species, individuals with the recessive genotype aa are predisposed to disease. Homozygous do
Nataly_w [17]

Answer:

The homozygous dominant phenotype is higher than expected, indicating that evolution has occurred.

Explanation:

At the start there are 200 fishes in the pond, 100 of them are AA(50%) and 100 of them are aa(50%). Using the Hardy-Weinberg Equilibrium equation we can say that the gene frequency is

A=0.5

a=0.5

With those frequency, the expected percentage of offspring with dominant genotype will be:

AA= 0.5 * 0.5 = 0.25 = 25%

The number of homozygous dominant found is 35% which is higher than expected  (25%). Higher homozygous dominant frequency than expected means the Hardy-Weinberg Equilibrium is changed. In this case, evolution probably the cause that shifts the gene frequency.

The fact that choanoflagellates and collar cells of sponges resemble each other supports the inference that ________. Group of a
antoniya [11.8K]

Answer:

choanoflagellates and sponges are sister groups

Explanation:

The choanoflagellates are small unicellular organisms belonging to the Protista kingdom. These microorganisms are collared flagellates morphologically similar to the choanocyte cells of animal sponges, which have a central flagellum surrounded by a collar of microvilli. In consequence, it has been suggested that choanoflagellates may represent the closest living relatives of primitive metazoans (i.e., they are sister groups to sponges). This hypothesis has recently been supported by both molecular phylogenetic and comparative genomic analyses.
