Answers

Answer 1

Answer: The correct option is A.

Temperature of the water

Explanation:

This is because dependent variable is variable that cannot stand alone but depends on another. It is the effect in an experiment. It is what that is been measured or tested in an experiment. Temperature if the water is dependent variable because it's what is been tested or measured in that experiment. It depend on other variables.

Answers

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.

How do both sodium and potassium ions travel​

Answers

Answer:

Sodium ions pass through channels in the hydrophobic barrier that have been formed by membrane proteins. The crossing membrane is called facilitated diffusion because it is facilitated by the channel

Potassium ions have to be transocated through specific membrane transport proteins. It is then transported into the cell through potassium pumps with energy being consumed int the form of ATP.

The sodium-potassium pump goes through cycles of shape changes to help maintain a negative membrane potential. In each cycle, three sodium ions exit the cell, while two potassium ions enter the cell. These ions travel against the concentration gradient, so this process requires ATP.

The sodium potassium pump goes through cycles of shape changes . In this way they help maintain a negative membrane potential.

Describe the importance of a hypothesis in scientific inquiry.

Answers

Answer:

The fundamental concept of a theory is that there is no predetermined conclusion. A main feature of this phase of the experimental process is deriving conclusions from theories regarding the outcomes of possible studies and then conducting certain experiments to see if the predictions are supported.

Explanation:

A hypothesis is crucial in scientific inquiry as it serves as a testable and falsifiable explanation or prediction for a specific phenomenon or observation.

It provides a structured approach to investigating a research question and guides the design of experiments and data collection.

By formulating a hypothesis, researchers set a clear direction for their study and establish a basis for drawing conclusions based on evidence.

If the hypothesis is supported by data, it strengthens the understanding of the subject matter.

Alternatively, if the data refute the hypothesis, it encourages further exploration and refinement of scientific knowledge, promoting the advancement of understanding and discoveries in various fields.

The data showed that recently the alligator population has decreased. How could the decrease in the alligator population affect the other populations? Be sure to explain whether the gar population, the diving duck population, and the crab population will change, and why.

Answers

Answer:

The correct answer is -

Gar population: increase

crabs: decrease

diving duck: decrease.

Explanation:

As it is known that alligators eat gar in any aquatic ecosystem and gar depends on the crabs for their food and nutrition and share the crab population as food with diving ducks in a particular ecosystem. So if the alligator population decrease in the ecosystem then The gar population will increase as there are fewer or no alligators eating them.

And as the population of gar will increase then there would be a decrease in the population in crab population as there will be more gars to eat them and the population of diving duck will reduce due to the increase in the gar population which results in competition for the crabs as food.

Explanation:

Transcription is the process of transfer of genetic information from DNA to RNA, typically to a messenger RNA (mRNA). During transcription, a particular DNA sequence called 'gene' is used as template to create an mRNA which is subsequently used to synthesize a protein by the process of translation. During this process (transcription), Uracil (U) bases pair with Adenine (A) and replace thymine (T) bases in RNA.
