Which type of evidence provides the best support for the hypothesis that the ancestors of tetrapods evolved legs before tetrapods were first seen on land?
Answer:
" Fossil record" is the right answer.
Explanation:
Prior knowledge, comprising fossils, rests as well as impressions of species perfectly deposited throughout sedimentary rock throughout early archaeological eras.These are established upon this superpose law which always claims that perhaps the lower layers typically younger than the whole upper ones in uninterrupted factors leading.

An individual has type ab blood. The father has type a and the mother has type b. What is the individual's phenotype an example of
Answer:
Codominance
Explanation:
Codominance is a type of inheritance pattern in which two alleles of a gene both express themselves in a heterozygous state. Codominance occurs when neither of the two alleles involved are recessive instead both dominate simultaneously.
As described in this question, the father of an individual has type A blood and the mother has type B. However, the individual has type AB blood. This is because alleles for blood types A and B both phenotypically express themselves in the individual. Hence, blood type A and B are said to be codominant and the AB phenotype is showing an example of CODOMINANCE.
If 65,000 kcal are
available in the
producers trophic
level, how much
energy is available
to the secondary
consumers?
Answer:
13000 would be avalable because 10% is taken every time it is eaten so 65,000 with 10% taken out twice (20% of 65,000) is only 13,000 kcal available to the secondary consumers.
The expression of both alleles for flower color produces a new pink. this illustrates incomplete dominance. Which of the following would be correct phenotype ratio from a cross between two heterozygous pink flowers

C is the answer

Assuming these are carbon dioxide molecules, which way do you think the molecules will move and why?
A. Out of the cell. They want to move from high to low concentration (DOWN the concentration gradient)
B. Into the cell. They want to move from low to high concentration (UP the concentration gradient).
Answer:
A. Out of the cell. They want to move from high to low concentration (DOWN the concentration gradient)
Explanation:
Although the cuticle provides important protection from excessive water loss, leaves cannot be impervious because they must also allow carbon dioxide in (to be used in photosynthesis), and oxygen out. These gases move into and out of the leaf through openings on the underside called stomata (Figure 3b).
Answer:
A. Out of the cell. They want to move from high to low concentration (DOWN the concentration gradient)
Explanation:
The option (A) is the correct answer. This statement is the required answer.

One of the pieces of evidence for evolution that Charles Darwin collected on his travels aboard the HMS Beagle was the observation of fossils of extinct animals and similar, but noticeably different species. Giant ground sloth fossils were very similar in shape to the bones of sloths that inhabited the regions of South America he was exploring. The main difference was the size, as the ground sloth fossils were significantly larger that the bones of the sloths he captured alive. What was a conclusion that Darwin was able to arrive to based on this piece of evidence
Answer: Darwin was able to arrive at a conclusion that there was no relationship between the fossils of the ground sloth and the bones of the captured sloths that currently reside in South America.
Explanation:
Evolution is defined as the sum total of adaptive changes that have taken place over a very long period of time. It leads to the development of new species from earlier ones. Evolution is an extremely slow process. It is difficult to obtain direct evidence of evolution in action. However, scientist such as Darwin, have gathered a great deal of indirect evidence that supports the theory of evolution. These evidence comes from many sources including:
--> fossils records
--> biochemical similarities
--> molecular records
--> Comparative anatomy and
--> embryology.
FOSSILS RECORDS shows the existence of species that are now in extinct which lived on Earth during different periods of the planet's history. They provide evidence that organisms from the past are not the same as those found today due to adaptive changes that has occurred over a long period of time on the organism in order to survive in its environment.
There was no relationship between the sloths because of the difference in BONE MASS.

Explain why an observer in New York State sees some different constellations in the night sky when Earth is at location A compared to when Earth is at location C.
Answer:
The Earth is Rotating to another location and shownig different groups of Stars
Explanation:
An observer in New York State sees some different constellations in the night sky when Earth is at location A compared to when Earth is at location C because of the continuous rotation of the earth on its axis.
What do you mean by Constellation?A constellation may be defined as a collection of stars that significantly form a recognizable and identifiable pattern in the sky mostly in the nighttime. These collections of stars are traditionally named after their apparent form or identified with a mythological figure.
According to the context of this question, when an observer in New York State sees some different constellations in the night sky when the earth is at location A, but the visualization by an observer may change when the earth is located at location C, this is because of the gradual and continuous rotation of the earth on its axis.

Phosphorylation of ADP to ATP occurs
A. via ribosomes on the endoplasmic reticulum.
B. in the nucleus
C. in the mitochondria
