Which best explains why water boils in a pot sitting over fire?

Heat energy is created from the thermal energy in the air.
Heat energy is transferred from the water to the fire.
Thermal energy from the fire moves to the water in the form of heat.
Thermal energy from the surrounding air moves to the water.

Answers

Answer 1

Answer: Thermal energy from the fire moves to the water in the form of heat.

Because according to second law of thermodynamic, heat flows from higher to lower temperature region. Heat is the transfer of energy from an object at higher temperature to an object at a lower temperature. so energy flows from warmer to colder objects

The pancreas is a human body organ that produces digestive enzymes and two very important hormones : insulin and glucagon. These two hormones work together to regulate the level of the sugar glucose in the bloodstream. If glucose levels in the bloodstream are too low, the pancreas secrets glucagon which causes the glucose level to increase. if blood levels are too high, the hormone insulin will lower the glucose level. if a person has just eaten a meal containing a large amount of sugar and other carbohydrate, which statement best describes how the pancreas will respond.

what does the process of breaking and reforming bonds allow cells to make?

Answers

Synthesis releases energy because the molecules bond to form a stable configuration and therefore give up energy. The bonded molecules have a lower energy level than free molecules and are held in the new bond.

The process of breaking bonds between molecules and the making or reforming of bonds encompasses chemical processes which allows the creation or formation of new molecules.

When bond is broken such that a certain element splits from a compound, new molecule is formed. Endothermic processes required energy to break bonds between atoms.

Bond making on the other hand are exothermic processes which involves merging of bond accompanied by the release of energy to form new molecules.

Therefore, bith Endothermic and exothermic processes allows cells to make new molecules.

Which of these is a characteristic of sexual reproduction?A)It takes place in all cells of the body.B)It forms exact copies of the parent cell.C)It results in offspring with genetic variation.D)It requires only one parent to form a daughter cell.

Answers

Answer/Explanation:

It results in offspring with genetic variation. 2 different mates must be used in sexual reproduction. This is because each person is different since cells are produced and combined differently in the original offsprings. If the two adults were exactly the same, the offspring would have the exact same cell traits. Likewise will be done for the offspring of the two adults. The genes may be similiar to the ones of the adults, but since combined it will not be an exact replica. In the long run sexual reproduction will result in an offspring with slightly different traits or genetic variation.

If a father has type A blood and the mother has Type AB blood, they would NOT have a child with which of the following blood types?

AB

A

B

O

Answers

Answer:

If a father has type A blood and the mother has type AB blood, they cannot have a child with blood type O, although depending on the father's genotype, they may not have children with a B blood type either.

Explanation:

Blood type is determined by the presence or absence of surface antigens A and B, which is genetically determined and establishes the pattern of inheritance.

Alleles that define the presence of antigens A and B are co-dominant, while the absence of antigens - as in blood type O - is a recessive trait.

Type A contains antigen A and its genotype can be A|A or A|O. Type B contains the B antigen, whose genotype can be B|B or B|O. Blood type AB contains both antigens and a single genotypic expression A|B Type O blood lacks surface antigens, with genotype O|O.

The father with blood type A can have two genotypes, A|A or A|O, which raises 2 possible scenarios:

1. Father A|O with mother A|B

Alleles       A         O

A              A|A      A|O

B              A|B      B|O

In this case there is no chance of having a child with blood type O, 50% chance of having children with blood type A, 25% B and 25% AB.

2. Father A|A with mother A|B

Alleles        A        A

A               A|A     A|A

B               A|B     A|B

50% chance of having a child with blood type A and 50% with blood type AB. In this case there is no chance of having children with blood type O or B.

a
Cenozoic
b
Mesozoic
c
Paleozoic
d
None of These

Answers

Answer:

C. Paleozoic

Explanation:

Trilobites are a group of extinct marine arthropods. Just like many animals from today, including crustaceans, spiders, and insects, they belonged to the phylum Arthropoda. They lived in the Paleozoic era.

We can make this conclusion based on the fact that the period they existed in (from 521 to 250 million years ago) mostly fits the period described as Paleozoic (from 541 to 252 million years ago). However, we can see that they went extinct in the Mesozoic (250 million years ago is more than 252 million years ago). Compared to the entire time they existed, 2 million years is a relatively small amount of time, which makes Paleozoic the correct option.

Alexis is using models of the cell membrane to compare the types of cellular transport. One

model shows a molecule entering through a protein pump. Which ope of cell transport is
being modeled?
A
diffusion because protein pumps are needed to move substances from a higher
concentration to a lower concentration
8
endocytosis, because protein pumps transport substances that are too large to
pass through the cell membrane
active transport, because protein pumps are needed to move substances against a
concentration difference
D
osmosis, because protein pumps allow water to cross the cell membrane

Answers

Answer:

C. active transport, because protein pumps are needed to move substances against a concentration difference

Explanation:

There are two major types of transport in living cells namely: passive transport and active transport. The passive transport moves molecules down a concentration gradient and hence, do not need energy (ATP) to occur. However, on the other hand, ACTIVE TRANSPORT moves substances against their concentration gradient, thus, require energy input.

Active transport makes use of PROTEIN PUMPS to achieve this process. Hence, in this case where Alexis is using models of the cell membrane to compare the types of cellular transport. The model that shows a molecule entering through a protein pump is modelling ACTIVE TRANSPORT.

Answers

Answer:

The correct answer is - B. the chemical properties of the peptide bonds.

Explanation:

The difference between the structures of catalase from other proteins depends on the chemical properties of the peptide bonds present in between the amino acids which decide the pH and temperature by their disruption. These bonds present between two alpha-amino acids when carboxyl of one amino acid interacts with the amino group of the other to form an amide-type covalent bond.

Edmentum sample explanation:

Technological advancements in the future could lead to the production of higher-efficiency turbines, which could generate more electricity than originally predicted. Climate changes over time could affect wind speeds in a region, leading to higher or lower energy production.

The factors that would exert influence through the process of natural selection are a natural selection: diseases; artificial selection: and genetic engineering. The correct option is C.

What is natural selection?

The strongest survive through natural selection, and the most favored traits endure through evolution. Natural selection is the result of selection pressure on a population's frequencies of a specific allele. Evolution is the process through which, over an extended period of time, new sets of naturally selected organisms emerged.

Future technological developments might result in the creation of turbines with a higher efficiency, which might produce more electricity than was initially anticipated. Wind speeds in a place may alter as the climate shifts through time, which could result in increased or decreased energy output.

how do the weight of objects on earth compare the weight of the objects on the moon why do you think this is

Answers

Answer:

Being that the moon has a gravitational force of 1.622m/s 2, we multiply the object's mass by this quantity to calculate an object's weight on the moon. So an object or person on the moon would weigh 16.5% its weight on earth. Therefore, a person would be much lighter on the moon. Conversely, a person is 83.5% heavier on earth than on the moon.

Explanation:

hope this helps you out love!! <3

Answer:

weight of objects on EARTH> weight of objects on MOON

Explanation:

weight= mass * gravity

assuming both objects have the same mass, the environment with greater gravity will result in a greater weight

gravity of earth > gravity on the moon

so

weight of objects on EARTH> weight of objects on MOON
