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 are the chromosomes called when they look like Xs
Answer:
I think you're referring to the Metaphase...
Explanation:
During Cell Division (or, rather before!) the DNA needs to be replicated. This normally is done by DNA Polymerase, and results in two identical double strands (the "Sister Chromatids".
These chromatids are held together at the Centromere, which will be the heart of the "X"-shape. After that the DNA is packed into Chromosomes by winding it around proteins called Histones. If I remember correctly there are 5 different Histones.
This "Zipping Up" makes the chromosomes more visible.
As the two sister chromatids are still connected, the result is the X-shaped Metaphase Chromosome....
The chromosomes are called "sister chromatids" when they look like Xs.
What are these chromosomesDuring cell division, specifically during the phase called mitosis, chromosomes replicate themselves, resulting in two identical copies joined together. Each of these copies is referred to as a sister chromatid. Sister chromatids are held together by a structure called the centromere, giving the appearance of an X-shaped chromosome.
The X-shaped appearance of chromosomes is a characteristic feature observed during certain stages of cell division, particularly during metaphase and anaphase, when the chromosomes are highly condensed and visible under a microscope.

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).

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.

What cannot form when two plates collide?
Volcanoes
⊝
Deep Sea Trenches
⊝
Mountain Ranges
⊝
Rift Valleys
Answer:
D. Rift Valleys
Explanation:
A landform refers to a geomorphic or natural feature of the Earth's surface, which typically makes its terrain. Some examples of landforms on planet earth are mountain, plains, valley, hills and plateau.
Basically, the tectonic plates such as the oceanic and continental lithosphere interact in three (3) ways and these are; divergent, transform and convergent boundaries.
A convergent plate boundary can be defined as a boundary where two (2) plates move towards each other, usually, resulting in subduction or collision. This action often causes mountain range such as the Himalayas to form by the collision between the plate carrying Eurasia and that of India; as a result of subduction which causes a plate to be forced underneath the mantle, deep ocean trenches are formed such as the Mariana trench.
Hence, Rift Valleys cannot form when two plates collide because they are formed only when the tectonic plates of earth rift or move apart. Also, Rift Valleys are found at the bottom of oceans and on land.
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
