Which evolutionary mechanism increases inheritable variations

Recombination of genes
Bottleneck ig of genes
Gene flow
Genetic drift

Answers

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.

Individuals with advantageous traits for their environment have a better chance of surviving
than those with less helpful traits. Explain how this is demonstrated in the moth information
above. Use specific information and examples.

Answers

Answer:

The moths with darker coloring lived long enough to reproduce and passed the trait on. The light peppered moths were easier for predators to spot on the dark soot covered trees so they died first.

Explanation:

Priscilla was building a circuit that used copper wires to connect a battery to a light bulb. As she connected the final wire from the light bulb back to the battery, the light bulb turned on. Priscilla knew that current was now flowing through her closed circuit. What makes the current in the circuit flow?

Answers

Answer:

The complete path provided by the closed circuit enables electric current produced by the battery to flow round the circuit

Explanation:

Electric current consists of charges (electrons) in motion from one region to another.

An electrical circuit is any closed path through which electric current can flow.

An electrical circuit consists of an energy source that supplies the electrons moving, a path along which the electrons can travel, and a load or appliance that uses the electrical energy. When the circuit is broken at any point, electrons will cease to flow since there is no complete path for it to flow. Such a circuit is known as an open circuit.

In the circuit built by Priscilla, the battery serves as a source of energy by providing the electrons that moves round the circuit. The wires provides the path for electrons to flow from the battery through the light bulb and back to the battery. When she connected the final wire from the bulb back to the battery, the circuit becomes complete/closed and current then flows to light up the bulb.

Which conclusion is supported by this evidence? Neither ball has a charge. The balls are both positively charged. One ball is positively charged, and the other is negatively charged. Each ball has a charge, but the type of charge is unknown.

Answers

Answer:

The correct answer is - Neither ball has a charge

Explanation:

If the two balls are hanged near one another without touch or an external charge to any of the balls there would be no charge present. In the given question is it given that two balls hang down without any contact in them.

So there is no possible way to generate charge and remain uncharge in their position till they get any external charge.

The correct answer is - Neither ball has a charge

What are the 3 common characteristics of planets? Describe one of the characteristics of one of the planets in our solar system

Answers

Answer:

The solar system is host to two broad categories of planets. The four closest to the sun — Mercury, Venus, Earth and Mars — are the terrestrial planets. They have rocky surfaces enclosed by relatively shallow atmospheres. The gas and ice giants — Jupiter, Saturn, Uranus and Neptune — are outliers. They are much larger than the terrestrial planets, but their cores are small and icy. Most of their size is formed by a combination of gases that become denser and hotter as you get closer to the core. Scientists count eight planets overall. Pluto was reclassified as a dwarf planet in 2006.

How can we tell histologically that skeletal muscle tissue is highly vascular?

Answers

Answer:Muscle tissue is composed of cells specialized for contraction. Muscle is classified into three types according to their structure and function:

Skeletal muscle cells - striated, voluntary control

Cardiac muscle cells - striated, involuntary control

Smooth muscle cells - nonstriated, involuntary control

Skeletal and cardiac muscle cells are called striated because they show an alternating series of bands. The repeating arrangement of their basic contractile unit, the sacromere, produces these striations.

In all types of muscle, contraction is caused by the movement of myosin filaments along actin filaments.

The terms muscle cell and muscle fiber are synonymous.
