Explanation

During systole, the right ventricle pumps blood into the pulmonary arteries (to the lungs).

The left ventricle pumps blood into the aorta (to the rest of the body).

Explanation

Cremocarp is a dry schizocarpic fruit that splits into two one-seeded mericarps.

It is commonly found in plants of the Apiaceae (Umbelliferae) family, like fennel and coriander.

Explanation

They are scavengers that feed on a wide variety of organic material.

Explanation

The capsule is a protective, gelatinous layer outside the bacterial cell wall.

It helps bacteria avoid phagocytosis and enhances their ability to cause disease.

Explanation

Step 1: Recall Ohm's Law

V = IR, where V is voltage, I is current, and R is resistance.

Step 2: Convert current to amperes

300 mA = 0.3$ A

Step 3: Calculate the resistance

R = V/I = 1.5/0.3 = 5 Ω

Explanation

The absorption of X-rays in a given material follows an exponential curve, described by the Beer-Lambert law:

I(x) = I₀ × e^(-μx)

where I(x) is the intensity of the X-rays after passing through a thickness x of the material, I₀ is the initial intensity, μ is the linear attenuation coefficient, and x is the thickness of the material.

Explanation

Petroleum, coal, and natural gas are all fossil fuels formed from the remains of ancient plants and animals.

They are non-renewable energy sources and major contributors to global energy production.
