The right answer is: C) Iruptive Growth. For their growth is never stable.
Answer:
1. False
2. False
3. True
Explanation:
1. Compliance is the capacity of a container to increase in size to allow it hold more content. Blood vessel, arteries and veins expand (increase in volume) to be able to accommodate a surge in blood flow, which is as a result of an increase in pressure of the blood from the heart pumping of the blood
Therefore, compliance in the tendency for blood vessel volume to increase as the blood pressure <em>increases</em> not decrease
The statement is false
2. A large compliance is indicative of being highly sensitive to changes in pressure
Compliance, C = ΔV/ΔP
From the above equation, a blood vessel with a large compliance, exhibit a large increase in volume when the increase in pressure is small
Therefore, the statement 'Blood vessels with a large compliance exhibit a small increase in volume when pressure increases a small amount; is false
3. The compliance of the vein ranges from 10 to 20 times (30 times in some literature) greater than arteries. A factor which can be affected by the vascular smooth muscle contraction or relaxation
Therefore, the statement, 'venous compliance is approximately 24 times larger than arterial compliance, so as venous pressure increases the volume of veins greatly increases' is true
<span>Alleles
Each human body is composed of genes, and these usually come in pairs that are slightly different from each other. The different versions of genes are called alleles. Alleles are responsible for determining physical or notable characteristics and traits a specific person has. </span>
Answer:
A
Explanation:
choice C would be tempting to choose but the the amount of molecules of a compound most of the time only 1 unless stated otherwise. The more obvious answer is that you can find the amount and kind of atoms in the compound.
Answer:
A. spiral galaxies are not pinwheel-shaped
Explanation:
There are three types of galaxies that include spiral galaxy, elliptical galaxy and irregular galaxy.
Elliptical galaxies are round shaped as well as elongated. Elliptical galaxies have both old and new stars but mostly it contains old stars.
Spiral galaxies are pinwheel-shaped due to the regular spinning motion of dust, stars and gas around the galactic center, at speeds of hundreds of kilometers per second which allows the matter to take a pinwheel-shape. Spiral galaxies are made up of lot of gas and dust and forms many new stars which allows the spiral galaxy to shine bright.
Irregular galaxies do not have any definite shape because of the gravitational influence of close galaxies. They also have many new stars.
Hence, the error is foudn in first sentence, where it says that spiral galaxies are not pinwheel shaped. so teh correct option is A.
