In the bonds of atoms and molecules

-Dr. Walter Snelling discovered in 1911
-it is a gas becomes a liquid under moderate pressure or when cold
-it is a portable energy source used in Barbecue grills in hot air balloons

what is it?

Answers

The gas that Dr. Walter Snelling discovered in 1911 that becomes a liquid under moderate pressure and acts as an energy source is propane.

Properties of Propane

Propane is a gas at room temperature and it was isolated by Dr. Walter Snelling around 1911 in the process of trying to stabilize gasoline.

At cold temperatures or moderate pressure, propane becomes a liquid.

Propane has been and is still being used as an energy source in cooking, powering vehicles, and cutting metals in industrial welding.

How do you think a species population can benefit from being diverse?

Answers

Answer:

A species' population that is genetically diverse is more likely to adapt and recover from environmental changes. A genetically diverse population is more likely to possess variations of alleles that are suited for the environment and its changes. Those individuals are more likely to survive to produce offspring bearing that allele.

Which of the following is not true of energy in a cell?
The cell must have energy to maintain homeostasis.
O Energy can be created by the cell.
O The cell uses mostly chemical energy.
O Energy can be converted by the cell.

Answers

Answer:

I think is the top one A hope this helps

Cells have a different function it can convert chemical energy to another form of energy to maintain homeostasis, and cells cannot create energy only change the form of energy, hence option b is correct.

What is the energy of the cell?

Every cell must continue to check its levels of energy and adjust ATP production rates in line with metabolic demand in order to keep homeostasis.

The ability of cells to sense, and convert nutrients into chemical energy is essential for the continuous fulfillment of this energy demand.

To drive metabolic reactions that would not happen automatically, to transfer necessary substances across membranes, and to do mechanical work, such as moving muscles, cells need chemical energy.

Therefore cells use energy to maintain homeostasis and can change one form of energy into another but can not create energy, hence option b is correct.

In cats, white spots are caused by a dominant allele called T, while (tt) individuals are solid colored. Also short hair(H) is dominant to long hair(h). What would the probability be of getting a white-spotted, long-haired cat from this cross: TTHh x Tthh? What are the phenotypes of the parents?

Answers

Answer:

1. Probability is 1/2

2. Parents phenotypes:

TTHh = white spots, short hair

Tthh = white spots, long hair

Explanation:

This question involves two different genes coding for spot color and hair length in cats respectively. In the first gene, the allele for white spots (T) are dominant over the allele for solid color (t) while the allele for short hair (H) is dominant to long hair (h).

According to this question, a cross between parent cats was performed as follows: TTHh x Tthh. The following gametes will be produced by each parent:

TTHh - TH, Th, TH, Th

Tthh - Th, Th, th, th

Using these gametes in a punnet square (see attached image), 16 possible offsprings will be produced. However, according to the question, 1/2 of the offsprings will probably be white-spotted and long-haired. The phenotypes of the parents are as follows:

TTHh = white spots, short hair

Tthh = white spots, long hair

15. Describe how the structure of the bird respiratory system provides the energy the
bird needs for flight.

Answers

Answer:

The bird's respiratory system consists of paired lungs, which contain static structures with surfaces for gas exchange, and connected air sacs, which expand and contract causing air to move through the static lungs.

Birds do not have a diaphragm; instead, air is moved in and out of the respiratory system through pressure changes in the air sacs. ... Bird lungs do not expand or contract like the lungs of mammals. In mammalian lungs, the exchange of oxygen and carbon dioxide occurs in microscopic sacs in the lungs, called 'alveoli.'

Air sacs are found as tiny sacs off the larger breathing tubes (tracheae) of insects, as extensions of the lungs in birds, and as end organs in the lungs of certain other vertebrates. They serve to increase respiratory efficiency by providing a large surface area for gas exchange.

How do birds respire?

Some birds can sing while they fly! ... When the bird takes a second breath, the air in the lungs is sucked into the cranial air sacs -caudal thoracic, cervical, and clavicular. The cranial air sacs act as a holding chamber which provides a small back flow of air into the lungs during expirations.
