Which evolutionary mechanism increases inheritable variations
Recombination of genes
Bottleneck ig of genes
Gene flow
Genetic drift
Answer:
Recombination Of Genes
Explanation:
Recombination of the gene's evolutionary mechanism increases inheritable variations, hence option A is correct.
What are genetic variations in a population?Gene flow, recombination, and mutation are mechanisms that enhance genetic variety. There are more mechanisms that work to promote genetic diversity, but fewer that work to reduce genetic diversity.
Demographic bottlenecks tend to decrease genetic diversity by intensifying genetic drift, but because genetic drift is random and has local impacts owing to recombination, mutation, and selection, the overall impact may vary along the genome.
Because it introduces new variety into the population, the mutation is the only mechanism of evolution mentioned that increases the amount of genetic variation. Genetic drift is the haphazard loss of genetic variation over time.
Therefore, option A is correct.

what 2 organisms are most closely related to eachother.....i need to know ASAP
Answer:
Family snapshot - chimps and humans are very closely related. Similarities are often easy to see when one looks at two organisms that evolved from a common ancestor, and until recently, looking at physical features and behavior was the only way to determine how closely related two organisms are.
HELPPP!!! What would the mass of an artificial cell containing 20mL of a 25% sugar solution be after it was placed in a beaker containing a 30% sugar solution for 30 minutes? Remember to include units in your answer.
Answer: The sugar will move from the 50 % concentration to the 0 % concentration.
Explanation:
Dialysis is an analytical technique which uses a semipermeable membrane in order to remove the impurities from the body.
This technique is used when the kidney failure inside the body takes place. The kidney inside the body perform function of filtration, when kidney failure takes place then the dialysis is used.
In this case the tubing bag containing 0% sugar is put into a sugar solution having 50% solution.
After sometime the sugar will move from 50 % to 0% bag because of the phenomenon known as osmosis.
If a bat, an alligator, and a bird evolved from a common ancestor, what most likely can be concluded
A. They are able to survive changes in their environments
B. They live in the same part of the world
C. They have similar anatomical structures
D. They are in the same biological classification
If a bat, an alligator, and a bird evolved from a common ancestor, most likely can be concluded that they have similar anatomical structures. Thus, option C is correct.
What are the different structures of animals?Structures of animals that have different appearances and functions but seem to have evolved from the same body part in a common ancestor. This can be found in Cat's leg and human arms.The structure do not need to look the same or perform the same functions.
The analogous structure evolve in different species living in two different geographic location with similar environmental conditions. Thus, the analogous structures have similar function and purpose but since they have not evolved from the same ancestor their structure vary a lot for example – wings in both birds and butterfly are meant for flight but their structure is entirely different.
The arrangement of bones is identical in all three organisms. This effectively means that all these organisms gradually evolved from a common ancestor.
Therefore, If a bat, an alligator, and a bird evolved from a common ancestor, most likely can be concluded that they have similar anatomical structures. Thus, option C is correct.

Some traits have multiple alleles (more than 2). What are the phenotypes for each of the four different alleles in the example provided?
Answer:
Although an individual gene may code for a specific physical trait, that gene can exist in different forms, or alleles. One allele for every gene in an organism is inherited from each of that organism's parents.
What does RNA do?
Is it just me or is every telling me to just die today.... like many of my friends said i should just kiII myself, that it would be better for everyone because no one would miss me... or is that juts me?
Answer:
The RNA carries out these instructions; it copies and transfers the genetic code from the DNA to ensure the relevant proteins are made. So just think of it as “DNA makes RNA make proteins”. Whereas DNA stands for deoxyribonucleic acid, RNA stands for ribonucleic acid.

B.
Species pick traits they like.
C.
Over time, species become more like their ancestors.

The San Marcos salamander, Eurycea nana, is a light reddish-brown translucent salamander about 2-5 cm in length. E. Nanais foundonly inSpring Lake and a portion of the San Marcos River.
Complete question:
The San Marcos salamander, Eurycea nana, is a light reddish-brown
translucent salamander about 2-5 cm in length. E. nana is found only in
Spring Lake and a portion of the San Marcos River.
Which human activity would most likely decrease the ability of the
salamanders to survive?
The addition of a new food source into the river that limits competition for
resources
Tourism that helps fund the educational programs related to river ecosystem
conservation
Public transportation that reduces the number of automobiles that contribute to
pollution runoff into the river
Increasing water consumption that decreases the flow of clean water from the
springs that feed the river
Answer:
Increasing water consumption that decreases the flow of clean water from the springs that feed the river
Explanation:
In this question we are required to state the human activity that may likely cause the reduction in the survival rate of the salamander.
the first three options in the question are not the answer to this question. this is because options 1,2,3 would have positive impacts on the Salamander. these positive impacts would increase the ability of the salamander to survive and not decrease it as the question says.
the correct answer is the last option. that is the 4th option. because it has to do with decreasing the amount of water that flows in to the Salamanders habitat by human activities. if humans increase water consumption, then the flow of clean water would reduce. This would then have a negative effect on the Salamander.
Belinda asked her teacher, "What could make turtles go faster?"
Her teacher replied, "I don't know. See if you could find out."
So Belinda did a lot of research in the library and come upon the idea that
eating carrots will make turtles go faster. She decided to test her ten turtles.
She fed five turtles their normal turtle food. She fed the other five carrots. All
the turtles got their normal sleep and water requirements. Then, after a week
she had a turtle race. She kept a record of the times and realized that she was
wrong. In fact, all the carrot-eating turtles finished last.
How was the dependent variable measured?
The amount of sleep the turtles received
How fast the turtles ate
The turtle's speed in the race
How much the turtles ate

The tRNA molecules in Lucy's white blood cells. RNA Pairing Rules A ↔ U G ↔ C Anticodon CCA Codon GGU.
What are anticodons?Once the mRNA codon has been translated by the ribosome, transfer RNA, also known as tRNA, is in charge of directing the appropriate amino acid into protein synthesis. Because of this, each mRNA codon needs a corresponding tRNA anticodon.
Each nitrogenous base in RNA must mate with a complementary base according to the following rules:
Adenine is complementary with uracil A=U
Cytosine is complementary with Guanine C=G
In this case, it can be seen that:
For the anti-codon: CCACodon: GGUAminoacid: GlyTherefore, for the tRNA anticodon CCA the corresponding codon is GGU, which codes for the amino acid Glycine (Gly).
