Which of these is a characteristic of sexual reproduction?A)It takes place in all cells of the body.B)It forms exact copies of the parent cell.C)It results in offspring with genetic variation.D)It requires only one parent to form a daughter cell.
Answer/Explanation:
It results in offspring with genetic variation. 2 different mates must be used in sexual reproduction. This is because each person is different since cells are produced and combined differently in the original offsprings. If the two adults were exactly the same, the offspring would have the exact same cell traits. Likewise will be done for the offspring of the two adults. The genes may be similiar to the ones of the adults, but since combined it will not be an exact replica. In the long run sexual reproduction will result in an offspring with slightly different traits or genetic variation.

A. photosynthesis and nitrate absorption
B. cellular respiration and the citric acid cycle
C. photosynthesis and dehydration synthesis
D. glycolysis and nitrate absorption
Answer:
1. ATP
Explanation:
Cellular respiration may be defined as the chemical process of breakdown of food in the cell with the liberation of energy in the form of ATP.
Photosynthesis is a chemical process through which green plants most photosynthetic algae synthesize their own food in the form of glucose. While nitrate absorption is the process through which nitrogen in the soil is significantly absorbed by the root of plants in form of nitrates.
Fermentation is initiated with the process of glycolysis, but it does not involve the upcoming two stages of aerobic cellular respiration such as the Krebs cycle and oxidative phosphorylation.
Therefore, each of the above questions is well described above.

1. Explain how forces of attraction and repulsion exist within an atom.
Answer:
Oppositely charged particles attract each other, while like particles repel one another. Electrons are kept in the orbit around the nucleus by the electromagnetic force, because the nucleus in the center of the atom is positively charged and attracts the negatively charged electrons.
Explanation:
Answer:
1. Electrons surrounding a nucleus are attracted to the protons within it because electrons and protons have opposite charges. Electrons closest to the nucleus are attracted with such a force that they can’t escape from the atom. These electrons tend to shield the protons from electrons that are farther away because electrons have the same charge and repel each other. Electrons that are farther away have less attraction to the protons within the nucleus and are more likely to be detached from the atom.
2. Electrons can be transferred from atoms of one body to atoms of another body through friction. This can occur when one body is rubbed against another or when a liquid flows across a solid. In either case, one body may be given a positive charge while the other body is given a negative charge of the same magnitude. Both charges are developed at the same time. Electrons can also be transferred from one body to another when a charged body comes into contact with an uncharged body. The electrons move in the direction that will equalize the charges; thus, the uncharged body will be given the same charge as the charged body.
3. Free electrons move from points of negative charge to points of positive charge. When these electrons move freely from one point to another with little resistance, the material they’re traveling through is said to be a conductor. Conductors have a large number of free electrons. Insulators, on the other hand, have very few free electrons and offer great resistance to the movement of these electrons. Electric charges produced on one end of a body composed of insulating materials will most likely not spread throughout the body. In a conductor, this charge would spread throughout the entire body. Metals are generally conductors; oils, rubber, air, porcelain, and plastics are good insulators.
4.
Lightning is produced by the rapid transfer of free electrons when one of the following conditions exist: One part of a cloud is positively charged and a neighboring part of the same cloud is negatively charged. A positively charged cloud comes near a negatively charged cloud. A cloud with either a positive charge or a negative charge comes near the earth.Explanation:

Read the excerpt from "Bone Detective," by Lorraine Jean Hopping. While the dentist worked on the tiger’s teeth, Diane made an alginate impression of one of its huge paws. Then, the dentist used two cupped hands to pull the tongue out of the big cat’s mouth. The heavily muscled organ was almost as long as her foot. With the dentist still holding the tiger tongue in both hands, Diane quickly went to work. The pink surface was rough, like sandpaper, but floppy and wet. She coated the top with alginate and waited for it to set. Her 15 minutes were almost up. The tiger, so calm and soft, would soon wake up and be dangerous again. Slowly and carefully, Diane peeled off the soft impression to avoid tearing it. Based on this excerpt, what is the author’s attitude toward Diane France? The author feels Diane is rough and impatient in her work with the tiger. The author feels Diane is skillful and careful in her work with the tiger. The author feels Diane is anxious and distracted in her work with the tiger. The author feels Diane is light-hearted and humorous in her work with the tiger.

The most basic definition of cellular respiration is that it is cells breaking down food to make energy. True or false?
Answer:
True
Explanation:
In cells, energy is obtained from food through the process of cellular respiration. In mitochondria, this occurs through aerobic respiration- here, cells breakdown sugars like glucose into carbon dioxide and water and energy in the form of ATP or adenosine triphosphate.
In cellular aerobic respiration:
C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP

How does this equation represent the law of conservation of energy—that energy cannot be created or destroyed? Consider the role of photosynthesis in your answer.
Answer:
Energy from the sun goes into making the sugar molecule. This energy is released to make ATP and heat.
Explanation:
6Co2+6H20->C6H12O6(glucose)+6O2(oxygen)
The sugar molecule is created by solar energy. This energy is discharged to produce heat and ATP.
What is the law of conservation of energy?
According to the rule of conservation of energy, energy can only be transformed from one form of energy to another and cannot be generated or destroyed.
This indicates that unless energy is introduced from the outside, a system always has the same quantity of energy. In the situation of non-conservative forces, when energy is changed from mechanical energy to thermal energy yet the overall energy does not change, this is especially perplexing. Energy must be changed from one form to another in order to be used.
In photosynthesis,
6CO + 6H₂O → C₆H₁₂O₆ + 6O₂
Sunlight is used for the light energy required to produce the sugar molecule.
Therefore, the law of conservation of energy is applicable in photosynthesis as energy from the sun is utilized by all living organisms.

Make a prediction of this: A group of scientists recently proposed the idea that beets should replace salt for melting winter ice. The scientists pointed out that because beets grow underground, they continue to grow in freezing conditions. Thus, they hypothesized, an extract of beet roots could melt ice on roads in winter. To test this hypothesis, the scientists froze equal volumes of water on two separate plates. They spread an extract of beet roots on one plate of ice and sprinkled an equal amount of salt over the other plate. After keeping both plates at 0°C (the temperature at which water freezes) for a period of time, they measured the amount of melted water on each plate. Their results showed that the plate treated with beet extract contained more liquid water than the plate treated with salt.
Answer:
extract of beet roots could be used as antifreeze for water systems
Explanation:
In science, a prediction can be defined as a plausible conjecture that is subsequently proved (or rejected) using the scientific method. In other words, a prediction is the expected result obtained if the hypothesis is true. Scientists make predictions based on falsifiable hypotheses which can be tested through experimental and/or observational procedures. In this case, it could be predicted that the extract of beet roots could be used as anti-freeze for water systems in cold climates.

Answer:
B. Paternity
Explanation:
Edge 2020
The career that combines DNA technology and forensics is paternity testing. The correct option is B.
What is paternity testing?DNA testing examines an individual's DNA banding patterns to determine the identity or mutations of a specific gene.
Paternity testing is a type of DNA testing that is used to determine paternity and the true nature of a relationship.
The lab compares tissue samples from the mother, the child, and the man to determine what unique characteristics known as genetic markers the child shares with the mother and the man who may be the father.
The chromosomes that determine the gender of the baby (X and Y chromosomes). The mother's egg typically contributes an X chromosome, while the father's sperm contributes either an X or a Y chromosome.
These tests are extremely accurate in determining whether a man is the biological father of a child.
Thus, the correct option is B.
