In order to create a big storm, the HIGH LEVEL TEMPERATURE had to be... A.Very Cold B.Cold C.Cool
Question:
In order to create a big storm, the HIGH LEVEL TEMPERATURE had to be... A.Very Cold B.Cold C.Cool
Answer:
A, because in order to create a big storm, the temperature has to be at least 40-20 degrees Fahrenheit (below 30 is freezing point, aka snow), and that would be weather where you would need to wear a thick jacket and warm pants.

Because the offspring are not getting genetic material from another organism.
Explanation:
Mr. Shepherd is at a football game on a cold day. How does his body maintain a relatively constant body temperature? What is this process called?
Answer:
1. Mr. Shepherd maintain a relative constant body temperature by preventing loss of heat.
2 This process is called HOMEOSTASIS
Explanation:
Homeostasis is the process whereby living organisms maintain a stable internal environment despite changes in conditions to the external environment. It is necessary that the body undergoes this process in order to guarantee survival.
According to this question, Mr. Shepherd is at a football game on a cold day. This means that in order to maintain a stable internal temperature, the body must preserve heat in the body and prevent its loss via sweating.
The regulation of body temperature is maintain fundamentally by the thermoregulatory center located in the preoptic region of the hypothalamus, this process is called homeostasis, which is the balance that occurs in the internal environment.
The main thermoregulatory mechanism is the increase or decrease in blood flow to the skin, through vasodilation and vasoconstriction.
Thermal sensing cells or thermal sensors for heat and cold are located on the skin surface (peripheral receptors), in the pre-optic region of the anterior hypothalamus (central receptors) and in other parts of the body.When it is hot, blood circulation to the skin increases (it becomes red) and when it is cold it decreases (the skin becomes paler).In addition to blood flow, the body also uses sweat to regulate temperature, sweating evaporates water on the surface of the skin and heat is lost, thereby lowering body temperature.Therefore, we can conclude that the maintenance of body temperature is closely related to another important indicator, the internal environment (homeostasis).

Which of the following might be an adaptation for a predator? AS SOON AS POSSIBLE NEED HELP PLS THX
Answer:
we need the answers
Explanation:
Answer:
Many predators have adaptations that help them survive in the wild. For example, the snake shown below has camoflauge coloring to look like its surroundings. This gives it the element of surprise when going to attack its prey. These adaptations help the predator in hunting for food. Predators have "weapons", or adaptations, that help them hunt and kill prey. Predators' three main "weapons" are teeth, claws, and jaws. The lion below has all 3 of these "weapons" or adaptations that are used for catching its prey. A lion has sharp claws for catching and grabbing hold prey such as a zebra, and strong jaws and teeth for biting and killing the zebra and for ripping off and chewing the meat.

2.How many moles of methane react with 10.7 moles of oxygen?
3.How many moles of carbon dioxide are produced from 80 moles of methane?
4.How many moles of water are produced from 800 moles of methane?
5.How many grams of oxygen will react with 85 grams of methane?
Answer:
the moles of oxygen react only 1.05 moles
Explanation:
because the formula of methane is CH4 so it has 10 molecule so 10.5 ÷10 =1.05
How are carbon dioxide and oxygen exchanged in the lungs?
A. Large blood vessels constrict and enlarge near the the lung tissue so gases can be exchanged.
B. Carbon dioxide and oxygen are exchanged in the aorta.
C. Small blood vessels pass next to the air sacs of the lung, gases are exchanged across a thin membrane.
D. The walls of the arteries thicken, harden, and lose their elasticity so that oxygen can pass through them.
Lung air sacs are surrounded by small blood veins, and a thin membrane allows for the exchange of gases (option C).
What is the purpose of oxygen?The chemical process that generates energy and powers the metabolisms of most living things, respiration, depends heavily on oxygen. The oxygen in the air that we breathe is essential for the survival of humans and many other animals.
O2 gas is it just O2?The sole sort of atom in oxygen makes it a chemical element, which is a substance. An oxidizing agent has eight atoms in its nucleus, as indicated by its atomic number of 8, which is represented by the letter O in its official chemical formula. At room temperature, oxygen is a gas that lacks all other flavors, smells, and colors. Molecular oxygen can be found in nature.
