11. Tom broke his leg. He was in a cast for six weeks. After his cast was
removed he had a hard time walking - WHY? *
Answer:
what-
Explanation:
Answer:
Well, the reason is because those muscles that he was once using every day, were suddenly on break and were not being used for the entire 6 weeks. Leading him to having some trouble walking.
Explanation:
When you don't use your muscles, they start to kind of chill out and get weaker in this case. So when you break your leg, and the doctor tells you not to put pressure on it, it is so that the bone can heal. But while your bone heals, the muscles in your leg are not able to move or do very much of anything because you can't put any pressure on them. So that is why when you take the cast off, you have to ease back into the regular motion in your leg that you had before.

Discuss some of the advantages to having a cycle that partially replenishes itself. In the Calvin cycle, what would happen to the cycle if there was no carbon dioxide available?
Answer:
The carbon atoms used to build carbohydrate molecules come from carbon dioxide, the gas that we exhale with each breath.
Explanation:
Dark reactions are also referred as "light independent reactions" (since they can occur during day or night) or as "carbon-fixation" (since carbon dioxide is taken from the air and carbon is affixed to compounds in the plant) or as the Calvin Cycle (named for the person who discovered it).
.Which of the following lists contains only arthropods?
A
annelids, insects, myriapods CADA STAVI819 UAB
B.
arachnids, crustaceans, myriapods
С
crustaceans, insects. molluscs
D insects, myriapods, nematodes
Answer:
Arachnids, crustaceans, myriapods.
Explanation:
Arthropods are animals that form the phylum Euarthropoda. This phylum includes the arachnids, crustaceans, myriapods, and insects. The defining characteristic for an animal to be considered an arthropod is that it has to have an exoskeleton, meaning that the skeleton of the animal is acting as a shell to the body, covering it from the outside.
At present, all of the species of arthropods are small in size, though in the distant past there were speciemens that can be considered as medium-sized or even large. The exoskeleton has its advantages and disadvantages. An advantage is that it is very hard and it covers fully the internal organs, thus protecting them. A disadvantage is that it limits the size to which these animals can grow as the exoskeleton cannot support the weight of the body after certain point.

why is active transport needed to take mineral ions into the cytoplasm of the root hair cell?
Answer: In plants, they need to move mineral ions from the soil into the roots. Mineral ions are more concentrated in the cytoplasm of plant cells than in soil water or dillute.
Explanation:
Minerals cannot be soaked up through osmosis since it only involves the movement of water. Because the minerals are in such low concentration, they cannot be absorbed through diffusion. Active transportation is used instead.
What is active transport?Active transport refers to the transport of molecules or ions into or out of a cell via the cell membrane, from a low concentration region to a high concentration region.
The particles use the energy released during respiration to move against the concentration gradient.
Active transport is defined as the movement of molecules against a gradient from a region of lower concentration to a region of higher concentration.
Active transport in plant root hairs allows plants to absorb mineral ions, which are required for healthy growth, even though the concentration of minerals in the soil is usually lower than in the root hair.
Thus, active transport is needed to take mineral ions into the cytoplasm of the root hair cell, as there is a need to move the minerals from the region of lower to higher concentration.

2.Which of the following is NOT an example of symbiosis? A. red blood cells containing malaria. B. vines using a tree for support C. nitrogen-fixing bacteria and the roots of legumes D. pigs feeding at a trough
Answer:
A. red blood cells containing malaria
Explanation:
Malaria is a disease-causing pathogen in humans. It is caused by species of the parasite Plasmodium sp., which is transmitted as sporozoites by the Anopheles mosquito upon biting the host. These travel through the bloodstream to the liver where they mature into merozoites. These reenter the bloodstream and mature into trophozoites and schizonts that produce more merozoites.
When they multiply within the red blood cell, they burst the red blood cell open, and go on to infect other cells. This infection's symptoms are cyclic and include high fever, chills and other flu-like symptoms.
Malaria is a deadly illness, causing harm to its hosts, and in many cases death. Thus, this cannot be defined as symbiosis, which is typically beneficial to both organisms.

Fully explain how cellular respiration is a chemical process whereby the bonds of food molecules and oxygen molecules are broken and the bonds in new compounds are formed resulting in a net transfer of energy.
Cellular respiration is a metabolic process called cellular respiration that converts glucose to ATP.
What is cellular respiration?Cellular respiration has the processes: Glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation are the phases of cellular respiration.
A glucose molecule gradually decomposes into carbon dioxide and water during cellular respiration. In the process of transforming glucose, some ATP is directly created.
But far more ATP is later created through a procedure known as oxidative phosphorylation. The electron transport chain, a collection of proteins enmeshed in the inner membrane of the mitochondrion, is what drives oxidative phosphorylation.
Therefore, Cellular respiration is a metabolic procedure by which glucose is changed into ATP.

If an individual has the genotype Bb, what alleles can it pass on to its
offspring?
A. Only B
B. Neither B norb
C. Either B or b
D. Only b
If a person possesses the genotype Bb, either the B or the b alleles can be passed on to their progeny. So, the correct option is C.
What is Genotype?An organism's genotype is made up of all of its genetic components. The alleles or variations that an individual carries inside a specific gene or genetic region are also referred to as the genotype.
The term "genotype" relates to an organism's whole gene pool, or, in other words, the genetic make-up of that creature. The phrase can also be used to describe to the alleles, or different forms of a gene, that an organism carries in a more specific meaning. Symbols can be used to symbolise it. For illustration, BB, Bb, and bb could be used to denote a certain gene variant.
If a person has the genotype Bb, as in the example above, then either the B or the b alleles can indeed be passed on to their progeny.

Why can't the air just rise and go up?
it's sinking
it's spinning
Air does rise and go up. For example, hot air rises because when you heat air (or any other gas for that matter), it expands. When the air expands, it becomes less dense than the air around it. The less dense hot air then floats in the more dense cold air much like wood floats on water because wood is less dense than water. keep this in consideration though, as the hot air cools and sinks back to the surface of the earth, there it gets warmed by the ocean only to rise again. This is called a convection current. In conclusion, air does indeed rise and go up.

Experiment 5
Lisa is working on a science project. Her task is to answer the question:
"Does Rogooti (which is a commercial hair product) affect the speed of hair growth"? Her
family is willing to volunteer for the experiment.
1. Identify the hypothesis in this experiment.
2. State a conclusion to support your hypothesis. 3. State a conclusion that refutes the hypothesis.
Answer:
Hypothesis: The commercial hair product Rogooti accelerates hair growth.Conclusion 1: Rogooti makes hair grow faster than it would normally do when using an ordinary product.Conclusion 2: Rogooti does not seem to have any effect on hair growth.Explanation:
A hypothesis is a scientific conjecture, not verified, that requires corroboration. It is a possibility, but not a fact.
A hypothesis must express what is expected to occur comprehensively. There must be a logical relation between variables. It must be objective.
To answer the question, Lisa might propose the following hypothesis, which needs to be corroborated.
Hypothesis: The commercial hair product Rogooti accelerates hair growth.
Experiment: Her family is a volunteer for the experiment, so all of them will use an ordinary hair product for a month. Before and after this period they will take notes of how long their hair is before and after the first part of the experiment. After this, they will cut down their hair to the initial length, and they will start using Ragooti for another month. After this last one, they will measure hair length again. Finally, Lisa will compare the initial length with the one after the first month and after the second month to analyze how Rogooti affects the speed of hair growth.
Result 1: When comparing lengths, Lisa will see that the hair of all her family members grew longer during the second month.
Conclusion 1: Rogooti makes hair grow faster than it would normally do when using an ordinary product.
Result 2: When comparing lengths, Lisa will not see any significant difference in the hair growth of her family during the first and the second month.
Conclusion 2: Rogooti does not seem to have any effect on hair growth.
