Answer:
Carbon dioxide is added to the atmosphere by human activities. When hydrocarbon fuels (i.e. wood, coal, natural gas, gasoline, and oil) are burned, carbon dioxide is released. During combustion or burning, carbon from fossil fuels combine with oxygen in the air to form carbon dioxide and water vapor.

How does the amount and type of fuel impact the distance a spacecraft can travel?
A space ship's momentum will continue to carry it forward indefinitely at a constant speed after the engines are turned off.
What do you mean by momentum?Momentum in a simple way is a quantity of motion. Here quantity is measurable because if an object is moving and has mass, then it has momentum. If an object does not move then it has no momentum.
Momentum, finance, refers to the capacity for a price trend to sustain itself going forward. Strong momentum can continue in an upward or downward trend, which can be confirmed by changes in trading volume and other technical indicators.
Momentum is how we measure mass that is in motion. Any moving object will have momentum. Under the law of physics, the object's momentum equals mass times velocity. Momentum is affected by the parameters' mass as well as velocity.

Do you believe that all of our actions can be attributed to the nervous system? Does your memory of an event trigger your responses? Why or why not?
Answer:
The nervous system is made up of all the nerve cells in your body. It is through the nervous system that we communicate with the outside world and, at the same time, many mechanisms inside our body are controlled. The nervous system takes in information through our senses, processes the information and triggers reactions, such as making your muscles move or causing you to feel pain. For example, if you touch a hot plate, you reflexively pull back your hand and your nerves simultaneously send pain signals to your brain. Metabolic processes are also controlled by the nervous system.

Which two changes would increase the density of ocean water?
A. Increasing the amount of light that enters it
B. Decreasing its salinity
C. Increasing the amount of water that evaporates from it
I D. Decreasing its temperature
Answer:
The answer is simply D.
Explanation:
One factor that does affect density is the temperature. In general, most substances become less dense as temperature increases and more dense as temperature decreases.
The amount of water that evaporates from the ocean and the temperature are the two factors that influence its density. So options C and D are both true for this statement.
What is the effect of temperature on density?
The ocean water has more salts and minerals dissolved in it, so it is denser than normal fresh water. Some factors further decrease or increase the density of the ocean water. When the temperature drops, the water cools and ice forms. The ice is denser than the water, so it will sit below it.
As the temperature rises, the water evaporates, increasing salinity because more salts are present in the ocean water than in the water itself. The concentration of salt in the ocean determines the salinity of the ocean, and it can increase the density of ocean water when the concentration of salt is higher.
Hence, the amount of water that evaporates from the ocean and the temperature are the two factors that influence its density. So options c and d are both true for this statement.

ATP is to your cells as ______ is to a car
Answer:
Gas to a car
Explanation:
The ATP function in the cell is equal to the gas or fuel function in the car, as the ATP gives energy to the cell for different functions like the fuel gives energy to the car to move from one place to another.
What is the function of the ATP?
ATP is produced in the cell from the food that living organisms, such as animals and plants, consume and use to produce ATP. There are different reactions that together make ATP, such as glycolysis, the Krebs cycle, and the electron transport chain, and with the help of ATP synthase, ATP is made. It performs a variety of cellular functions, including protein synthesis, food digestion, message transmission from one cell to another, and so on.

Distinguish the types of forgetting: anterograde amnesia, retrograde amnesia, encoding failure, retrieval failure, and interference (both retroactive and proactive).
Answer:
Anterograde amnesia is the inability to create new memories after the onset of amnesia, while memories from before the event remain intact. Brain regions related to this condition include the medial temporal lobe, medial diencephalon, and hippocampus. Anterograde amnesia can be caused by the effects of long-term alcoholism, severe malnutrition, stroke, head trauma, surgery, Wernicke-Korsakoff syndrome, cerebrovascular events, anoxia, or other trauma. Retrograde amnesia is the inability to recall memories made before the onset of amnesia. Retrograde amnesia is usually caused by head trauma or brain damage to parts of the brain other than the hippocampus (which is involved with the encoding process of new memories). Brain damage causing retrograde amnesia can be as varied as a cerebrovascular accident, stroke, tumor, hypoxia, encephalitis, or chronic alcoholism. The there is encoding failure. Encoding is the process of converting sensory input into a form able to be processed and stored in the memory. However, this process can be impacted by a number of factors, and how well information is encoded affects how well it is able to be recalled later. On the other hand, retrieval failure is the failure to recall information in the absence of memory cues. Proactive interference occurs when old memories hinder the ability to make new memories. In this type of interference, old information inhibits the ability to remember new information, such as when outdated scientific facts interfere with the ability to remember updated facts. This often occurs when memories are learned in similar contexts, or regarding similar things. It’s when we have preconceived notions about situations and events, and apply them to current situations and events.Retroactive interference occurs when old memories are changed by new ones, sometimes so much that the original memory is forgotten. This is when newly learned information interferes with and impedes the recall of previously learned information. The ability to recall previously learned information is greatly reduced if that information is not utilized, and there is substantial new information being presented. This often occurs when hearing recent news figures, then trying to remember earlier facts and figures.

which of the following statements best describes how the traits of an organism are determined by the DNA in their cells?
Answer:
C. DNA codes for proteins which allow an organism to grow and function
Explanation:
Deoxyribonucleic acid, commonly known as DNA is the genetic material in living organisms. The DNA stores genetic information, which encodes the formation of useful products (proteins) necessary for the growth and development of that particular organisms. The information in DNA is decoded by a process called GENE EXPRESSION, which encompasses transcription and translation.
Transcription is the process that synthesizes RNA from DNA molecule, while translation synthesizes PROTEIN from the mRNA. Hence, the order which is called CENTRAL DOGMA OF BIOLOGY is as follows: DNA → RNA → PROTEIN.
Therefore, DNA codes for proteins which allow an organism to grow and function best describes how the traits of an organism are determined by the DNA in their cells.

True breeding plant round seeds (DD) were bred with true breeding smooth
seeds(dd) to produce F1 offspring. F1 offspring were then bred with other F1
offspring. What is the genotypic ratio of the resulting F2 offspring? What is the
phenotypic ratio of the resulting F2 offspring?
Answer:
Genotypic ratio F2 = 1:2:1
Phenotypic ratio F2 = 3:1
Explanation:
In this case, parental genotypes can produce only one type of gamete, i.e., one parent can produce only D gametes, while the other parent can produce only d gametes. Therefore, all F1 generation will be heterozygous (Aa). An F1 hybrid is the first filial generation of offspring obtained from crossing between different parent types. The F1 will produce two gametes (A; a) in a ratio 1:1, thereby the F2 obtained by crossing F1 offspring will have a phenotypic ratio of 3:1 (3 D_; 1 dd) and a genotypic ratio of 1:2:1 (1 AA; 2 Aa; 1 aa).

Explanation:
hahahahahaahahahaha
In DNA, different alleles of a gene have a different sequence of nucleotides. Alleles may have a different sequence of nucleotides in RNA that result in a different sequence of amino acids in a protein. Therefore, proteins produced from different alleles of a gene may have different structures and functions and result in different characteristics.
What are nucleotide?Nucleotides are the building blocks of DNA and RNA. They are composed of a sugar, a phosphate group, and a nitrogenous base. There are four types of nitrogenous bases in DNA: adenine (A), cytosine (C), guanine (G), and thymine (T). In RNA, the base thymine is replaced by uracil (U). The sequence of nucleotides in DNA or RNA determines the sequence of amino acids in a protein. Proteins are made up of long chains of amino acids, and the sequence of these amino acids determines the protein's three-dimensional structure and function.
Alleles are different versions of a gene. They can result from mutations or changes in the DNA sequence. Different alleles of a gene can produce proteins with different structures and functions, which can result in different characteristics in an organism. For example, the gene that determines eye color has several different alleles, which can result in different eye colors in people.
