which heats up faster
Water or air

Answers

Answer 1

Answer:

Air

Explanation:

Air.

Why? Because air has a much lower specific heat capacity (Heat capacity - Wikipedia) per unit mass than water. Also, air is dispersed as a gas so that in any given volume the mass of air that would fill it is only a fraction of the mass of water that would fill the same volume. Take these two factors into consideration and you see that the amount of energy it takes to raise the temperature of a volume of air by one degree is minuscule compared to the amount of energy it takes to heat the same volume of water by one degree.

The one thing that is more challenging about air is actually getting the energy into it. Water is densely packed, whereas air molecules are much more widely separated, so that presents a heat conductivity challenge. However, if we’re talking about equipment specialized for heating air (i.e. a fan forcing air over heated coils) versus equipment specialized for heating water (flat plate, coils, pumps or no pumps, whatever), energy added at the same rate to each will heat an equivalent volume of air to a greater extent (i.e. raising temperature more quickly) that it will water.

In many tropical rainforests, people clear land by cutting down trees and burning them. After a few years, the soil runs out of nutrients and cannot be farmed any longer. How does this affect Earth's atmosphere?

Answers

Answer:

Land will convert into desert eventually

Explanation:

When the soil gets devoid of nutrient, it will be unable to support trees, plants or vegetation of any type. Trees and plants are responsible for holding the soil tightly and prevent it from eroding.

Once there will be no nutrient in soil, there will be no trees, plants or vegetation and hence there will be no mechanism to prevent soil erosion. Thus, the soil will erode due to deforestation and the land will convert into desert eventually

In corgis, a breed of dog, short tails are completely dominant to long tails. If two long-tailed corgis have puppies, what is the percent chance of having a puppy with a short tail?

Answers

Answer:

0%

Explanation:

This question involves a single gene coding for tail length in a breed of dog called Corgis. The allele for short tail (S) is dominant over the allele for long tail (s).

According to this question, two long-tailed corgis are crossed i.e. ss × ss. Each parent corgis will produce only 's' gametes. Using this gametes in a punnet square (see attached image), the following proportion of puppies will be produced:

All ss (long-tailed) offsprings/puppies.

Based on the question asked, 0% or none of the puppies produced will have a short tail.

What might occur if the stoma were all located on the top of the leaves?

Answers

Most stomata are located on the bottom of leaves because direct sunlight does not hit the bottom surface. If stomata were on the upper epidermis (the top side of the leaf), the direct sunlight hitting the leaf would cause more water to be lost through the stomata because of evaporation. Hope this helps!

Answer:

It depends on the plant and its environment. In a mesic terrestrial environment, the plant wouldn’t be optimized. Natural selection would then come into play and there would be an evolutionary trend towards stomata located on the lower leaf surface.

In the case of water lily, the lower epidermis is in contact of the water, and stomata are restricted to the upper surface of the leaf. This is an optimal solution for the plant. Natural selection will work to conserve that arrangement. In this case, stomata on the lower surface would exist at a water-air interface, and the diffusion of gasses across that interface would be glacially slow. Further, the stomata on the lower surface would present an opening where pathogens can enter the leaf.

Write a paragraph explaining the steps involved in a muscle contraction starting from the brain sending a signal to the muscle and ending with the muscle contraction.

Answers

Answer:

A Muscle Contraction Is Triggered When an Action Potential Travels Along the Nerves to the Muscles.Muscle contraction begins when the nervous system generates a signal. The signal, an impulse called an action potential, travels through a type of nerve cell called a motor neuron. The neuromuscular junction is the name of the place where the motor neuron reaches a muscle cell. Skeletal muscle tissue is composed of cells called muscle fibers. When the nervous system signal reaches the neuromuscular junction a chemical message is released by the motor neuron. The chemical message, a neurotransmitter called acetylcholine, binds to receptors on the outside of the muscle fiber. That starts a chemical reaction within the muscle.Acetylcholine Is Released and Binds to Receptors on the Muscle Membrane.

A multistep molecular process within the muscle fiber begins when acetylcholine binds to receptors on the muscle fiber membrane. The proteins inside muscle fibers are organized into long chains that can interact with each other, reorganizing to shorten and relax. When acetylcholine reaches receptors on the membranes of muscle fibers, membrane channels open and the process that contracts a relaxed muscle fibers begins:

Open channels allow an influx of sodium ions into the cytoplasm of the muscle fiber.

The sodium influx also sends a message within the muscle fiber to trigger the release of stored calcium ions.

The calcium ions diffuse into the muscle fiber.

The relationship between the chains of proteins within the muscle cells changes, leading to the contraction.
