Stand and let your hands hang next to your sides for a few minutes. Then, look at the backs of your hands. Do you see any bumps on the surface on top of your veins? What might those be, and what are their function?​

Answers

When you stand and let your hands hang next to your sides for a few minutes, the bumps you see on your veins are the valves that help move blood to the larger veins.

What we know about vein valves.

There are valves located throughout the veins in our bodies. Most of these are located in points where smaller venules fuse with the larger veins.

Their function is to prevent blood from flowing back into the smaller veins, thus helping with the normal blood flow of the body.

Given that the veins in our bodies are littered with small valves to help the blood return to the heart correctly, we can confirm that these are the small bumps that we can see when letting our hands down for a few mins, as they fill with the blood they try not to let flow back into the smaller veins.

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.

Answers

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.

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.

Answers

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.

Answers

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.

C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP

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.

Answers

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.

1. Explain how forces of attraction and repulsion exist within an atom.

Answers

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.

Answers

Answer:

1. ATP

Explanation:

Cellular respiration produces ATP. Thus, the correct option is C. To produce starch, glucose molecules bond together through dehydration synthesis. Thus, the correct option is C.The process through which yeast produces the carbon dioxide responsible for bread rising is known as glycolysis. Thus, the correct option is B. A component of amino acid that is not contained in starch is nitrogen. Thus, the correct option is D. Photosynthesis and nitrate absorption are the two processes that provide the glucose and nitrogen used to form amino acids in plants. Thus, the correct option is A.

What is Cellular respiration?

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.
