Answer:
When cells split and increase they do this very important thing in order tonmake the new cells exactly the same as the previous before them. Each cell makes more of all it's genes. Then each one.splits into two with one group of genes in each one of the new cells. During the process they make sure that all are copied correctly.

Need a 100% correct answer please
Answer:
During the day, the sun heats up both the ocean surface and the land. ... The wind will blow from the higher pressure over the water to lower pressure over the land causing the sea breeze. The sea breeze strength will vary depending on the temperature difference between the land and the ocean. At night, the roles reverse.

Explanation:
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?
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

Farmer Brown tests the hypothesis that the more alfalfa sprouts cattle eat, the more milk they produce. He divides his pasture into four fields and puts twenty cattle in each field. Field 1 cows get no alfalfa sprouts, field 2 cows get ten pounds of sprouts per day, field 3 cows get twenty pounds of sprouts, and field 4 cows get thirty pounds. He feeds all groups fifty pounds of regular hay per day, uses the same breed of cattle, and gives them the same amount of water. He measures gallons of milk produced per cow every day.

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.
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.

What is the difference between aggression and courtship?
Answer:
How you approach and talk to the person you like
Explanation:
If you go up and start saying inappropriate things or immediately try to kiss them then that is aggression. But if you go up and give them a subtle and light compliment like ''Hey I like your shirt" and start a conversation, maybe at the end ask (not demand) for her number, then that is a courtship. P.S.If you say something like give me your phone number, that is aggression.

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