What is the purpose of coolant/coolant pumps in a nuclear reactor? Explain how malfunctioning coolant pumps can lead to meltdown.
Answer:
The purpose of the reactor coolant pump is to provide forced primary coolant flow to remove and transfer the amount of heat generated in the reactor core. A nuclear reactor coolant is a coolant in a nuclear reactor used to remove heat from the nuclear reactor core and transfer it to electrical generators and the environment. Frequently, a chain of two coolant loops are used because the primary coolant loop takes on short-term radioactivity from the reactor.

Carbon tends to form four bonds. What kind of bonds are they?
O A. Covalent
O B. Ionic
O C. Hydrogen
O D. Metallic
Carbon tends to form four bonds. These bonds are called as covalent bonds. The correct option is A.
What are Covalent bonds?An atom can establish bonds with other atoms in two main ways: covalent and ionic. The sharing of electrons between two or more atoms forms a covalent connection. When two or more ions join contact, they can create ionic bonds that are held together by charge differences.
An electron exchange that results in the formation of electron pairs between atoms is known as a covalent bond. Bonding pairs or sharing pairs are the names given to these electron pairs.
Covalent bonding is the stable equilibrium of the attractive and repulsive forces between atoms when they share electrons. Through covalent bonding, carbon atoms form four bonds.
Therefore, the correct option is A.

Most scientists think that life arose spontaneously from nonliving chemicals in the “primordial soup” of ancient Earth. The formation of life from nonliving material is defined as spontaneous generation. Stanley Miller conducted an experiment to test the hypothesis of spontaneous generation. How did the experiment of Stanley Miller support the hypothesis of spontaneous generation of living organisms?
Answer:
Stanley Miller created an experiment where he sent an electrical charge through a flask of a chemical solution of methane, ammonia, hydrogen and water . This created organic compounds including amino acids .
The experiment supported the hypothesis that several organic compounds can be created in earth's early atmosphere , several organic amino acids can be created from inorganic raw material .

Which of the following biomolecules is best represented by this formula?
A.
nucleic acid
B.
protein
C.
carbohydrate
D.
lipid
Answer:
The correct answer is option D. "lipid".
Explanation:
Lipids, known also as fats or oils, are organic compounds that are insoluble in water and are made up of carbon, hydrogen, and oxygen. The formula of this question shows a biomolecule that is made up of this three atoms, and even though carbohydrate are made up of this three atoms as well, we can determine that it belongs to a lipid because it contains many more hydrogen atoms than oxygen atoms. Other characteristic of lipids is their long chains of carbon and hydrogen atoms, which are represented by the lines shown in blue. I attached the missing formula.

a. The most common way to determine the size of a population is to count or estimate the number of individuals in a number of samples.
b. A transect consists of a long triangle and a line of a certain length. The occurrence of any individual within a certain distance of the line is recorded.
c. Ecologists tend to use quadrats to sample a stationary population.
d. The density of a population is determined by determining the size of the quadrat and then dividing this by the average number of individuals in the quadrat.
Answer:
I think A. is the right answer.
Explanation:
I searched up on how to determine population size and here here are some things I found. ¨The number of individuals in a specific area¨, ¨The most obvious way to determine the size of a population is to count, one by one.¨, but one thing I´m kinda sure is right is this one. It´s determining population size. ¨Some methods of determining the size of population are direct and indirect observations, sampling, and mark-and-recapture studies¨ But just see for yourself.

Folded mountains form only at divergent plate boundaries, whereas shield volcanoes form only at convergent plate boundaries.
Folded mountains form only at convergent plate boundaries, whereas shield volcanoes form only at divergent plate boundaries.
Folded mountains form when hot, fluid rock rises through thin spots in Earth's crust, whereas shield volcanoes form when segments of Earth's crust are bent and doubled over.
Folded mountains form when segments of Earth's crust are bent and doubled over, whereas shield volcanoes form when hot, fluid rock rises through thin spots in Earth's crust.
Answer:
Folded mountains form when segments of Earth's crust are bent and doubled over, whereas shield volcanoes form when hot, fluid rock rises through thin spots in Earth's crust.
Explanation:
Folded mountain (Himalayas, Rockies, Alpha) refers to all the large mountains on planet earth.It is made up of sedimentary rocks.They are formed when two plates collide into each another, folding up:hence the name folded mountain.They are characterised with large granitic intrusion extending to many kilometers through the length, reaching the mountain edges.
This results from high magma supply rates ,which occurs during long term effusive eruptions.
They are recognised as broad, dome shaped structure, flowing downwards just like a shied used in battles,
Answer: D. Folded mountains form when segments of Earth's crust are bent and doubled over, whereas shield volcanoes form when hot, fluid rock rises through thin spots in Earth's crust.

Which comparisons of Trial A (no immunity) and
Trial C (50% immunity) did you include in your
explanation? Check all that apply.
After six points of contact, fewer people were
infected in Trial C than in Trial A.
On average, the slope of the graph for Trial C
was less than than the slope for Trial A.
Infection spread at a slower rate in Trial C than
in Trial A.
In addition to the ten immune people, three
nonimmune people did not become infected.
Help!!!!!
Answer:
1.
3.
4.
Explanation:
In trial A, people have no immunity so there are more chances of infection and in trial C, only 50% of people have immunity so chances of infection are less, so infection will spread faster in trial A than trial C.
If compared, trial C will have less infected people than trial A because people in trial A has no immunity and people in trial C have 50% of immunity, so only fewer people will get infected even after six point of contact.
As percentage of immune people (trial C) is 50, so there are equal chances of immunity and non-immunity. there are three reasons of infection that include source, susceptible person and transmission. source and susceptible person can be the reason of infection in some non-immune people but the transmission reason can vary. so, there is probability that three nonimmune people lie under transmission reason and are not coming in contact with infected people, medical equipment or environment, that causes infection and those three people are not getting infected.
Hence, the correct options are 1, 3 and 4.

Explain how science uses fossil evidence to support the theory of evolution.
Answer:
A: LAYER
Explanation:
simple i took the test
Fossil remains have been found in rocks of all ages. Fossils of the simplest organisms are found in the oldest rocks, and fossils of more complex organisms are in the newest rocks. This supports Darwin's theory of evolution, which states that simple life forms gradually evolved into more complex ones.
Evidence for early forms of life comes from fossils. By studying fossils, scientists can learn how much (or how little) organisms have changed as life developed on Earth.
There are gaps in the fossil record because many early forms of life were soft-bodied, which means that they have left few traces behind. What traces there were may have been destroyed by geological activity. This is why scientists cannot be certain about how life began.
Fossils provide a snap shot of the past and allow us to study how much or how little organisms have changed as life developed on Earth.
