Answer:
The thermal energy will flow from the computer to the person.
Explanation :
Usually computer are such devices which converts electrical energy into thermal energy and then it gets transferred to the person. The energy flows from the higher amount to lower amount. In this case, computer is producing higher thermal energy than the person that’s the reason for the flow of energy from computer to the person.
The thermal energy will flow from the computer to the person.
What do you mean by thermal energy?The energy in a system that controls its temperature is referred to as thermal energy. Heat is the progression of nuclear power. The first law of thermodynamics explains how heat and work are transferred between systems.
Bubbling water on an oven is an illustration of nuclear power. When a substance's atoms and molecules vibrate at a faster rate as the temperature rises, thermal energy is produced.
Utilizing steam power produced by burning oil, coal, liquid natural gas (LNG), and other substances to rotate generators and generate electricity is the process of producing thermal power.

Which of the following factors of a gene determines the protein, and therefore the trait, it expresses in a cell?
A. Its length and sequence of nitrogen bases.
B. Where the cell is found in the organism.
C. The position inside of the nucleus.
D. Its shape and color after cell reproduction.
Its length and sequence of nitrogen bases. Therefore, option (B) is correct.
What are nitrogenous bases?Nitrogenous bases are the building blocks of DNA and RNA, which are the genetic material of living organisms. They include adenine, guanine, cytosine, and thymine (or uracil in RNA), and their sequence in DNA determines the genetic code that directs the synthesis of proteins.
The length and sequence of nitrogen bases (adenine, guanine, cytosine, and thymine) in a gene determine the specific sequence of amino acids that make up a protein, and therefore the trait it expresses in a cell. This is known as the genetic code, which is a set of rules that determines how the sequence of DNA bases is translated into the sequence of amino acids in a protein.
The other factors listed (where the cell is found in the organism, the position inside of the nucleus, and its shape and color after cell reproduction) do not directly determine the protein or trait expressed by a gene.

Which term best describes two predators living in the same habitat who feed on the same prey?
A.coexistence
B.mutualism
C.competition
Answer:
The answer is C, competition
Competition refers to the interaction between the organisms to seek or feed on the same resource.
The term that best describes the two predators living in the same habitat feeding on the same prey is competition.
Competition can be defined as:
Competition in an ecosystem or habitat will take place when the ecological niche of organisms overlaps as both organisms try to use the same resource. In habitat, the predators feeding on the same prey will have competition, as the predators will fight for food, nutrients, and a source of energy to survive. Competition can be caused among animals due to food, space, and shelter.
Thus, the correct answer is Option C.

Jennifer observes a weather map showing tomorrow's weather. She predicts that air will travel from the low pressure system to the high pressure system, causing wind. The wind will carry moisture since it is coming from the ocean. Choose the statement which corrects the error(s) in Jennifer's prediction. (2 points)The wind from the ocean will not carry moisture.
The wind will travel from the high pressure system to the low pressure system.
Since the low pressure system is not over land, wind will not be created.
Wind is only created when two high pressure systems meet.
Answer:
Jennifer observes a weather map showing tomorrow's weather. She predicts that air will travel from the high pressure system to the low pressure system, causing wind. The wind will carry moisture since it is coming from the ocean.
Explanation:
Winds refers to the movement of air which are produced due to differences in air pressure.
These pressure differences are to uneven heating of the earth by the sun. Due to the uneven shape of the earth, regions around the equator receive a fairly consistent heating from the Sun. However, with increase in latitude north and south, there is more uneven heating of the earth's surface by the Sun. When air is heated, warm air rises up to the atmosphere. This produces a pressure difference and subsequently cold air sinks downward to replace it. This constant air movement results in winds. The winds generated moves from a high pressure system to a low pressure system. The greater the pressure difference, the greater the wind force.
When warm air from land rises, air from the ocean in to replace it. The wind coming from the ocean is moisture-laden, and results in precipation on land.

When cells divide during meiosis, homologous chromosomes separate
independently of each other and are randomly distributed to the gametes.
How does this process lead to genetic variability
During meiosis, gametes receive different combinations of genes, and the offspring resulting from fertilization has a unique set of chromosomes. After fecundation, independent assortment generates unique gene combinations in the new generation.
The independent assortment of homologous chromosomes leads to gamete containing different sets of genes.
During metaphase I of the meiotic cell division, homologous chromosomes line up at the equator plate of the cell in a random mode.
The consequence of this independent assortment is that gametes receive different gene combinations, which increase genetic variation in offspring and may eventually confer an evolutionary advantage.
The independent assortment of homologous chromosomes and the process of recombination by which non-sister chromatids interchange genetic material are well known to increase genetic variation in the resulting gametic (meiotic) cells.

What is one significant drawback to transferring electricity produced by solar energy from states where sunshine is abundant to states where it is not? Electricity made from solar energy is different from fossil fuels, so it needs new types of power lines. Electricity made from solar energy is different from fossil fuels, so it needs new types of power lines. The transfer could only occur during the day because solar energy cannot be stored. The transfer could only occur during the day because solar energy cannot be stored. Electricity produced from solar energy farms must be used locally and cannot be transferred at all. Electricity produced from solar energy farms must be used locally and cannot be transferred at all. The cost to transfer electricity produced by solar energy over great distances can be high.
Answer:
The transfer could only occur during the day because solar energy cannot be stored.
Explanation:
The transfer of electricity produced from solar energy only occur during the day because solar energy cannot be stored at huge level. At homes, we can easily store the electricity made from solar energy with the help of batteries but for providing electricity to a state where thousands of houses are present, very big batteries are needed to store it which can't be made due to very high cost so that's why the solar energy can not be stored.

Explanation:
why is active transport necessary for the absorption of amino acids in the blood stream
Answer:
Active transport is a mechanism that requires molecules to move against a gradient of concentration. The procedure needs energy.
The glucose molecules in the gut may be higher than in the intestinal cells and blood – e.g. after a sugar meal.
Explanation:
Active transportation is a process necessary for molecules to travel against gradient concentration. It takes energy to do this.
Ions are transferred to the root hair for the use of mineral ions in plants, which have an increased concentration compared to diluted soil solutions. Active transport occurs to enable the plant to take in the soil around the plant the nutrients it requires.
Glucose molecules in animals must be transported into the blood through the gut wall. In the intestine, glucose molecules may be more concentrated than in the intestinal cells and blood - following a sugar meal, for example. It will then spread from high intestinal concentrations to lower blood levels. This requires no energy.
However, glucose levels in the intestines may be lower sometimes. In that instance, active transport is involved in the transportation of glucose. This procedure requires breath-generated energy.
