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.

A researcher conducted studies on proteins obtained from mouse livers. He discovered a novel protein and decided to study its genetic origins. During his tests, the researcher found the mRNA sequence AUUCGGUACUGUACUAGC. What is the DNA sequence that was used for synthesizing this mRNA sequence?

Answers

Answer:

TAAGCCATGACATGATCG

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.

Explanation:

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.

Answer:

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

Plasma protein status. Albumin, globulins and fibrinogen are the major plasma proteins.

Blood proteins, also termed plasma proteins, are proteins present in blood plasma. ... Globulins make up 38% of blood proteins and transport ions, hormones, and lipids assisting in immune function. Fibrinogen comprises 7% of blood proteins; conversion of fibrinogen to insoluble fibrin is essential for blood clotting. Plasma proteins, such as albumin and globulin, that help maintain the colloidal osmotic pressure at about 25 mmHg. Electrolytes like sodium, potassium, bicarbonate, chloride, and calcium help maintain blood pH. Immunoglobulins help fight infection and various other small amounts of enzymes, hormones, and vitamins.

Of course, in order to really benefit from your studies, youll need to do more than just complete assignments. Youll need to set habits that will tie you to French and its cultures even beyond the classroom. Students who become lifelong learners of French have some basic characteristics and habits that you should develop if you want to get the most from your experience learning French. Here are some of them:Lifelong learners:Have friends with whom they regularly converse in the target language. (This could be friends in school, neighbors or friends in the community.)Regularly get information from target language sources, such as newspapers, magazines, Internet, French related news groups (with parents approval), TV programs, radio, etc.Participate in activities of the target culture (celebrating holidays, seeing movies or plays of/in the target culture, preparing or eating dishes from the target culture, reading books or magazines from the target culture, etc.)Someone who has developed these habits is on the way to becoming a lifelong learner. These types of habits reinforce a strong connection to the language and culture and develop a love and better understanding of that culture.Think for a minute about the resources available. Do you have friends who are native French speakers? Do you ever watch French channels on television? You can probably think of several online sources. Maybe you have some stores or restaurants in your community that are run or frequented by French speakers. Also think about when you could do this on a regular basisremember that its setting the habits that will make the most difference.Using the table below as a guideline, write what you plan to do. For the Language or Culture Resources column, try to identify three different resources: 1. A friend or contact, 2. An information source, and 3. A cultural activity. In the What I Will Do column, describe as specifically as you can what you will do. And in the When I Will Do It column, write when you plan on doing these activities. See the sample below to see how you might fill out your own table.You will have opportunities to follow up and report on your regular practice of engaging French resources close to home. You will be asked in a follow up assignment to report on what you have done. If you are still unsure where to begin, ask your teacher for additional ideas that can help get you started. Regardless of how you go about making your French cultural connection, be sure to make a plan and to think about a longer-term strategy for getting the most from your time with your chosen resources.
