What part of a microwave oven protects humans against radiation?
1. glass doors
2. plastic outer covering
3. metal shields
4. magnetrons
Answer:
metal shields
Explanation:
I took the quiz and exam
Humans are shielded from radiation by metal parts of a microwave oven. So, the correct option is C.
What is Microwave oven?A microwave oven, often known as a microwave or electronic oven, is a device that uses microwaves, which are high-frequency electromagnetic waves, to cook food. A microwave oven is indeed a compact, box-shaped oven that increases food's temperature by exposing it to an electromagnetic field with a high frequency.
Water, lipids, carbohydrates, and a few other molecules absorb the microwaves, which causes their vibrations to produce heat. Hence, cooking time is significantly shortened because the heating takes place inside the food rather than warming the air around it. Metal components of a microwave oven protect people from radiation.
Therefore, the correct option is C.

Answer:
Oxygen & glucose
Explanation:
Glucose and oxygen are the reactants and the end products are carbon dioxide and water with the liberation of energy in form of ATP.
Glucose is the substrate. It is broken down into CO2 and H2O in the presence of O2.
name one of the scientific principles trevor talks about when describing how the yo-yo is physics at work!! ANSWER QUICK
A scientific principle that is used in describing how the yo-yo is physics at work since it possesses energy.
The yo-yo is physics at work since it exhibits different types of force such as the angular movement, frictional force and force of gravity. The gravitational force can be found in the engine of the yo-yo. When the yo-yo is released, gravity pulls it down to the ground.Also, through the angular momentum, the object can keep spinning.

Explanation:
The presence or absence of freckles is determined by one gene. The allele for freckles (F) is dominant and the allele for the absence of freckles (f) is recessive. A couple has several children. All of the children have freckles because their parents' genotypes can only produce children with freckles. Which of these are most likely the genotypes of the two parents?
Answer:
There are no options to this question, however, the question can be answered. The answer is:
FF and FF/Ff
Explanation:
This question involves a single gene coding for possession or not of freckles in humans. The allele for freckles (F) is dominant over the allele for no freckles (f). This means that genotypes FF and Ff (heterozygous) will possess freckles while only genotype ff will not.
According to this question, a couple has several children in which all of the children have freckles i.e. have either genotype FF or Ff. This is as a result of the fact that the parent's genotypes were either FF or Ff. That is, one parent is FF while the other is either FF or Ff. This genotypes will only produce children with freckles.

Explain why just protecting a species like the grizzly bear with a law may not be enough to conserve this species?
Answer:
When laws are made to protect a species, it is made to stop human interference. Often natural factors also are the reason for a species decline, some of these factors may include, habitat change, climate change and may also be a disease going through the species. In order to truly save a species you would have to isolate them in an area and make sure they are all healthy and the habitat does not change. The only issue with that is, they could lose some of their natural instincts such as hunting or being scared of humans. So a law may not be enough to save a species because there may also be many natural factors interfering with a species survival.
Explanation:
How does variation lead to natural selection?
Answer:
Natural selection can not create variations it can only eliminate the existing variations that are not as well adapted to the changing environment as others. Natural selection acts like a racket. Natural selection preserves variations that are best suited to environment. Variations are known to create changes within a species. These changes are also known as adaptive evolution or micro evolution.
The variations required to create changes from one species to another species have never been empirically observed. These changes are known more correctly as Darwinian evolution or macro evolution.
Variations is the driving force in evolution or change. Natural selection can only act on existing variations. So for evolution of any kind to occur there must be variations.

what is the smallest part of a compound called
Which is most likely a physical change?
cutting a substance into four pieces
burning a substance into ash and smoke
reacting a substance chemically to form a new substance
combining a substance with water to make rust
Given what we know, we can confirm that a physical change would be slicing the substance into four pieces, option A is correct.
Why is slicing the substance a physical change?This has to do with the fact that this option focuses on the physical characteristics of the substance, such as the shape and size, whereas the other options would in one way or another affect its chemical nature, by reacting with fire, chemicals, or water respectively.
Therefore, we can confirm that a physical change would be slicing the substance into four pieces.

A fir tree has leaves that stay green all year long. These trees produce cones, and their reproductive structures can be dispersed by the wind. To which group does the fir tree belong? nonvascular plants angiosperms gymnosperms seedless plants
Answer:
gymnosperms
Explanation:
Gymnosperms are a diverse group of plant, second to angiosperms, that both belong to the HIGHER PLANTS category. Gymnosperms are characterized by their ability to bear seeds on naked structures called CONES. They do not produce flowers or fruits as opposed to gymnosperms.
They are usually evergreen i.e. do not shed their leaves all season long. According to this question describing a fir tree, which has leaves that stay green all year long and produce cones, that allows for wind dispersal, the fir tree is a GYMNOSPERM.

gymnosperms

Five little boys have been raped and killed in the past three weeks. All of them have died due to strangulation with a rope. There were no other person's fingerprints or body fluids on the bodies. The boys all lived in an area of Memorial Drive in Dekalb County. The police fear the killer will attack again. What specialist is needed to find or identify the killer and predict where he might strike next? Why?
Answer:
Forensic biologist
Explanation:
The specialist needed to find or identify the killer would be a forensic biologist. A forensic biologist uses trace samples or evidence in identifying victims and/or suspects and generally supporting criminal investigations with the aid of scientific techniques. In the case described in the question, there are other samples (aside from body fluids and fingerprints) that can be obtained from the crime scene; for example, in the case of a struggle with the killer, some of the boys could have pulled hair strands from the killer. The root of these hair-strand can be subjected to DNA analysis to identify the killer. There is also the possibility of having one of the boys scratching some skin cells from the killer; these could also be useful in DNA analysis.
The forensic biologist could also determine when and where the actual death of the boys took place, this information could be vital for the law enforcement in predicting where the killer might strike.
(AKS 1a/DOK 2) Usain Bolt was on his way to run a race. Before he left the house, his friend gave him an apple and said this will help you win the race.
Explain how eating the apple would benefit the runner
O A. The chloroplasts in the apple tree produced glucose which is the product of photosynthesis for the apple. When Usain ate the apple the glucose
provided energy for the mitochondria in his legs to increase his energy for the race,
B. The apple contains nucleotides from the tree's DNA, Usain ate the apple and used this DNA to help control the cells and run faster
OC. The apple tree performed cellular respiration in it's chloroplasts to produce protein in the apple which provided energy for Usains mitochondria in his
leg muscles
D. The tree produces lipids when it perfogms photosynthesis, these lipids then enter his golgi bodies where ribosomes make energy for him to run faster.
