The diagram below shows a light ray striking Medium A and Medium B at the same angle. (4 points)
A rectangle labeled Medium A is drawn on the left. A ray of light travels through air and strikes the surface of medium A making an angle of 50 degrees with the vertical. The light ray bends towards the vertical as it travels through Medium A and makes an angle of about 15 degrees with the vertical. A rectangle labeled Medium B is drawn on the right. A ray of light travels through air and strikes the surface of medium B making an angle of 50 degrees with the vertical. The light ray bends towards the vertical as it travels through Medium B and makes an angle of about 25 degrees with the vertical.
Which statement is correct?
The speed of the light ray is the same in air and Medium A.
The speed of the light ray is the same in air and Medium B.
Medium A and Medium B have different densities because light refracts at different angles.
Medium A and Medium B have the same density because the light ray strikes both at the same angle.
Answer:
A the speed of the light ray is the same in air and medium
Which of the following newborns has the lowest chance of having health problems?
A. Rosalind- 6 lbs
B. Charles- 11 lbs
C. Nikola- 7.5 lbs
D. Marie- 5 lbs
Answer:
C Nikola
Explanation:
7.5 ibs is the most average and ideal weight for newborns.
Rosalind is the newborn who the lowest chance of having health problems. Thus, the correct option is A.
What are health problems?Health problems may be defined as a situation of disease or medical ailment or an environmental condition that poses the threat of disease or medical ailment practically.
Rosalind weighs 6lbs which is equal to 2.72 kilograms. The most ideal and normal weight of newborns should be ranging in between 2.5 to 3 kilograms.

Which of the following statements can you infer would happen If one organ system stopped working?
a. The other organ systems would have to work harder to make up for the broken system
b. The other organ systems would stop working too.
c. The other organ systems would still work on their own but might have to work harder to complete their function correctly.
Answer:
b
Explanation:
After one system shuts down, the others would slowly start to shut down as well until the body can no longer maintain homeostasis and the person would slowly die. 3. All systems would be working together but the main ones would be muscular, nervous, and skeletal.
2. Slime moulds cannot be put neither in kingdom Plantae nor in kingdom Animalia. Give reason.
3. Give the disadvantages of the two kingdom classification.
Answer:
3. In the two-kingdom classification following are drawbacks:-
The plants comprised of photosynthetic and non-photosynthetic species. Fungi, that feed on dead organic matter, were placed under photosynthetic plants. There was another class of classification needed were the organisms with the same characteristics were clubbed into one kingdom. This system did not distinguish between the eukaryotes and prokaryotes, unicellular and multicellular organisms and photosynthetic (green algae) and non-photosynthetic (fungi) organisms. There are some organisms which neither fall into plant nor animal kingdom like Lichens.Explanation:-

Answer:
have variation that can be passed from one generation to the nextsurvive longer than another organismhave adaptations to their environment. have differential reproductive success.Explanation:
Naturla selection is the survival and reproduction of individuals due to different phenotypes. The naturla selection represents a mechanism of evolution and changes in traits of species.In order for natural selection to occur, organisms must :
have a variation that can be passed from one generation to the next.have differential reproductive success.Natural Selection is a mechanism of evolution that occurs when there is a heritable variation for a trait and individuals with one version of the trait have greater reproductive success than do individuals with a different version of the trait.
In order for natural selection to occur, three conditions must be met:
There must be variation for the particular trait within a population.The variation must be inheritableIndividuals with one version of the trait must produce more offspring than those with a different version of the trait.Thus,

The chemical reaction for cellular respiration will be C6H12O6 + 6 O2 → 6 CO2 + 6 H2O, the correct option is C.
What is cellular respiration?Cellular respiration is a succession of chemical reactions that break down glucose to produce ATP, which can then be used as energy to power a variety of reactions throughout the body.
Cellular respiration consists of three major steps: glycolysis, the citric acid cycle, and oxidative phosphorylation.
It is mirror image of photosynthesis, its chemical reaction is:

Which is the difference between an antibiotic and an antiviral?
Answer:
There are no options in this question, the options are as follows:
A. Antibiotics build up immunity, and antivirals increase white blood cells.
B. Antibiotics treat the symptoms, and antivirals destroy the causing organism.
C. Antibiotics are in liquid form, and antivirals are in mist form.
D. Antibiotics treat patients who have Staphylococcus, and antivirals treat patients who have the flu.
The answer is D
Explanation:
Specific drugs are used to curb infection or diseases caused by specific pathogens. An infection can be caused by either bacteria, virus or fungi. Considering their different mechanism of infection, viral infections are treated with the use of ANTIVIRAL DRUGS while bacterial infections are treated with the use of ANTIBIOTICS.
According to this question, staphylococcus is a bacterial genus and hence, patients with staphylococcus can be treated with antibiotics while flu is a viral disease, hence can only be treated with antivirals.

Explain how homologous and the fossil records support evolution.
Thanks so much!!!
Answer:
Los fósiles, una prueba de la evolucion. El estudio de los fósiles nos da una idea muy directa de los cambios que sufrieron las especies al transformarse unas en otras; existen muchas series de fósiles de plantas y animales que nos permiten reconstruir cómo se fueron adaptando a las cambiantes
Explanation:
Answer:
homologous: have identical position, value, or structure
Fossils: In the oldest rocks area unit fossils of the best organisms and within the newest rocks area unit fossils of additional advanced organisms.
Explanation:
The evolution theory is supported by multiple sorts of evidence: homologous structures show common ancestry, whereas similar selective pressure will manufacture similar variations. analogous structures (beneficial features).
In the oldest rocks area unit fossils of the best organisms and within the newest rocks area unit fossils of additional advanced organisms. This supports Darwin's organic process theory, whereby straightforward life forms {progressively|increasingly|more and additional} evolved into more advanced. Proof of adolescence forms comes from fossils.

All the following rely on ATP as a source of energy except
Select one:
a. the active transport of glucose from the small intestine to the blood
b. diffusion and osmosis across semi-permeable membranes
c. the movement of the flagella of sperm for motility
d. exocytosis of waste substances across a semi-permeable membrane
Answer:
b. diffusion and osmosis across semi-permeable membranes
Explanation:
ATP (adenosine triphosphate) is a high energy carrying molecule in the system of living organisms. It posseses the ability to store and release energy for use by organisms during biochemical activities. However, some processes do not require ATP to occur and are called PASSIVE TRANSPORT while those that require energy (ATP) are called ACTIVE TRANSPORT.
In the above options, the processes listed as follows require ATP to occur:
- The active transport of glucose from the small intestine to the blood
- The movement of the flagella of sperm for motility
- Exocytosis of waste substances across a semi-permeable membrane
However, the diffusion and osmosis across semi-permeable membranes, which is a passive transport does not require ATP.

1.Explain what makes a scientific experiment reliable. Be sure to include at least three reasons to support your answer.
2.During research, why is it important to use peer reviewed evidence when collecting background information during a scientific investigation?
Answer:
1:When a scientist repeats an experiment with a different group of people or a different batch of the same chemicals and get very similar results then those results are said to be reliable.Reliability is measured by a percentage if you get exactly the same results every
time then they are 100% reliable.
2.The peer reviewer determines whether the introduction provides sufficient background information on the research topic, and ensures that the research question and hypothesis are clearly identifiable.
