A mutation is a change in the DNA sequence that can be either beneficial or harmful. 1) B, false.

<h3>What is a mutation?</h3>

A mutation is a stable and hereditably change in the genetic material that introduces new variants.

These changes are unpredictable, and occur due to the action of mutagenic agents that alter DNI sequences.

Different mutagenic agents cause changes in genetic information, increasing mutations over the normal level.

Mutagenic agents cause changes in the base sequences and pairing.

Many of these mutations are eliminated, but some might succeed and be incorporated into each individual, getting to even affect the entire species.

These mutations are the ones that have been selected by natural selection.

Mutations depend on environmental conditions and ecological pressures, and accumulate in time. Mutations can be damaging or beneficial to the organism and might be inheritable or not.

Those favored by natural selection are inherited by the following generations and get to spread.

The statement is False, Option B.

Which five organs make up the vestibular system? A. Three semicircular canals and two otolith organs B. Two semicircular canals
enot [183]

Answer:

Option A

Explanation:

The vestibular system is a part of the inner ear that provides the most important contribution to the sense of balance and coordinating movement with balance. This system is made up of two parts which are the three semicircular canals and the two otolith organs. The two otolith organs are the saccule and the utricle. The utricle is sensitive to changes with regards to horizontal movement and the saccule provides information about vertical acceleration. They are able to do this due to their orientation in the inner ear providing spatial orientation with regards to movement and balance. the three semi circular canals includes the horizontl, poterior and the superior semicircular canals. they provide sensory inputs.

1. on the trace above
ser-zykov [4K]

Answer:

1. when there is cardiovascular disease.

2. High blood pressure increases the likelihood of suffering a stroke, a heart attack, heart failure, kidney disease or premature death.

3. The mitral valve opens.

Explanation:

1. High blood pressure is a common condition in which the force exerted by blood against the walls of the arteries over the course of time is high enough to cause you health problems such as heart disease. After the first rise of pressure caused cardiac ejection volume, one notch occurs with a second ascent product of the reflection of the pulse wave. In younger individuals, with elastic arteries, said wave occurs in diastole, so does not influence the peak systolic pressure. By contrast, with advancing age and the stiffness of large vessels, the reflected wave is transmitted prior to the aorta (systole) so as to increase the peak central PAS.

2. The pressure increases progressively the pressure of the blood flowing through the arteries. As a result, you can submit the following: Arteries damaged and narrowed. High blood pressure can damage the cells of the inner lining of the arteries.

3. When the pressure in the left ventricle falls below the pressure of the left atrium, the mitral valve opens, and the left ventricle fills with blood that had been accumulating in the left atrium.
