About the Heart and Circulatory System
The circulatory system is composed of the heart and blood vessels, including arteries, veins, and capillaries. Our bodies actually have two circulatory systems: The pulmonary circulation is a short loop from the heart to the lungs and back again, and the systemic circulation (the system we usually think of as our circulatory system) sends blood from the heart to all the other parts of our bodies and back again.

TRUE FALSE: Organisms can CHOOSE to have a mutation
Answer:
False
Explanation:
Organisms themselves cannot choose to have a mutation. However, it can be artificially done in labs.
Organisms can choose to have a mutation, but this is a false statement because mutation is not voluntary but involuntary and can be caused by many factors, such as environmental factors.
What is the significance of the mutation and its consequences?mutation has many consequences, such as the Mutations can cause developmental disorders such as birth defects, mutations can increase an individual's risk of developing genetic disorders, and they also reduce the genetic diversity of a population. Mutation leads to the loss of function in an essential gene, resulting in a decrease in the organism's fitness in the ecosystem.
Hence, organisms can choose to have a mutation, but this is a false statement because mutation is not voluntary but involuntary and can be caused by many factors, such as environmental factors.

There are _____ levels of intellectual disabilities on the modern continuum.
A.
five
B.
four
C.
three
D.
two
Answer:
B) Four
Explanation:
There are four levels of intellectual disabilities on the modern continuum. The correct option is B.
What are intellectual disabilities?A person is said to have an intellectual disability when their capacity to learn at a typical rate and function in daily life is restricted. The severity of intellectual disability in children varies widely.
Despite the fact that a precise full-scale IQ test result is no longer necessary for diagnosis, standardised testing is nevertheless used to help make the diagnosis.
A full-scale IQ score of between 70 and 75 denotes a considerable intellectual functioning restriction.
Each person's level of difficulty with learning and processing information, difficulties with abstract cognition, and issues with social interaction are all common aspects of intellectual impairments.
On the contemporary continuum, there are four stages of intellectual disability.
Thus, the correct option is B.

In the Calvin cycle the conversion of energy poor carbon dioxide into energy rich glucose
A) atp is used
B) pyruvic acid is produced
C) oxygen is produced
D) nadph is made
Answer:
D)NADPH is made
A)ATP is used
Explanation:
Sorry to ask the two questions, I asked why the two options are in the process:Reduction. In the second stage, ATP and NADPH are used to convert the 3-PGA molecules into three-carbon sugar molecules, glyceraldehyde-3-phosphate ( G3P ). At this stage, it gets its name because NADPH donates, or reduces , electrons to a three-carbon intermediate to form G3P.[Ocultar detalhes]
The reduction stage of the Calvin cycle, which needs ATP and NADPH, converts 3-PGA (produced in the fixation stage) into a three-carbon sugar. This process takes place in two main stages:
Simplified diagram of the reduction step of the Calvin cycle showing the carbon atoms, but not the complete molecular structures. A 3-PGA molecule first receives a second phosphate group from ATP (generating ADP). Then, the doubly phosphorylated molecule receives electrons from NADPH and is reduced to form glyceraldehyde-3-phosphate. This reaction generates NADP + and also releases an inorganic phosphate.

Then, the doubly phosphorylated molecule receives electrons from NADPH and is reduced to form glyceraldehyde-3-phosphate. This reaction generates NADP + and also releases an inorganic phosphate.
First, each 3-PGA molecule receives a phosphate group from ATP, becoming a doubly phosphorylated molecule called 1,3-bisphosphoglyceride (and leaving an ADP as a by-product).
Second, 1,3-bisphosphoglycerate molecules are reduced (gain electrons). Each molecule receives two electrons from NADPH and loses one of its phosphate groups, becoming a three-carbon sugar called glyceraldehyde-3-phosphate (G3P) . This step produces NADP^+

The ATP and NADPH used in these steps are products of the photo-dependent reactions (first stage of photosynthesis). That is, the chemical energy of ATP and the reducing potential of NADPH, both produced with the use of light energy, keep the Calvin cycle running. Conversely, the Calvin cycle regenerates ADP and NADP^+

If energy is released, free energy must be what?
Answer:
If energy is released during a chemical reaction, then the change in free energy from the conversion of the reactants to the products, signified as ΔG (delta G) will be a negative number.
Explanation:
Hope it helped!
Answer:
If energy is released during a chemical reaction, then the resulting value from the above equation will be a negative number. In other words, reactions that release energy have a ∆G < 0. A negative ∆G also means that the products of the reaction have less free energy than the reactants because they gave off some free energy during the reaction.

4. Which of the following statements best describes how proteins and enzymes move within a cell?
The movement of proteins and enzymes within a cell is facilitated by intracellular receptors.
The movement of proteins and enzymes within a cell is facilitated by special organelles called transport receptors.
The movement of proteins and enzymes within a cell is facilitated by special organelles called magneto receptors.
The movement of proteins and enzymes within a cell is facilitated by membrane receptors.
Answer:
The movement of proteins and enzymes within a cell is facilitated by intracellular receptors.
Explanation:
Proteins and enzymes (which also are proteins) move inside the cell through intracellular receptors. These receptors are proteins capable of binding other molecules such as proteins and hormones in order to transport them to different cellular locations. Thus, intracellular receptors are key players in signaling pathways that trigger signaling events to regulate a particular function, for example, activating gene expression by transporting proteins to the nucleus.

Traditionally most units of time are based upon a)the motions of earth, b)the longitude of an observer, c)the motions of the moon, or d)the real motions of the sun
Answer:
The correct answer is option A (the motions of Earth).
Explanation:
The word "Time" may have different meanings, "Time" in a simple term, it is used to measure events, and it is the bedrock that is used to determine seasons. Time is measured in seconds, minutes, hours, days, weeks, months, years. Unlike clocks, and other different devices used to measure time, these devices were not available some centuries ago. So, time was measured in those centuries with the help of the knowledge of the rising and setting of the sun which are caused by the rotation of the Earth. The most standard unit of time used this day are all products of research Astronomers were able to do through studying the motions of the Earth. For instance, when the Earth makes a full rotation around its own axis, that signifies a day, which is a period of about 24hours. considering we have leap years, so it is not complete 24 hours.
When a person eats the yogurt, the 14 grams of protein will be A combined into monosaccharides. B combined into polysaccharides. C broken down into amino acids. D broken down into nucleic acids.
Answer:
C broken down into amino acids.
Explanation:
Proteins are one of the four major biological molecules. They are organic polymers made up of monomers called AMINO ACIDS. Proteins are contained in food we ingest and are subsequently digested or broken down into their amino acid components.
In this case, when a person eats yogurt (containing proteins), the 14 grams of protein will be broken down into amino acids during digestion by enzymes called PROTEASES. Note that every polymer will be broken down into its monomeric constituents during digestion.

Use the diagram to answer the question. Between which parts of the molecule must the bonds be broken to form an ADP molecule?
The parts of the molecule whose bond must be broken to form an ADP molecule would be between C and D. Thus, option A would be correct.
The image is an illustration of the structure of ATP, Adenosine Triphosphate. The hydrolysis of the terminal phosphoanhydridic bond in ATP yields energy for metabolic reactions in biological systems and ADP (Adenosine Diphosphate) is formed as a result.
In this case, the terminal phosphoanhydridic is D. Thus, the bond between D and C must be broken for ADP to result.
