What common characteristics do all planets share?
A) Planets are made of gas, orbit the sun, and have atmospheres.
B) Planets are made of rock, orbit the sun, and have atmospheres.
C) Planets have moons, have atmospheres, and are made of rock, gas, or ice.
D) Planets have atmospheres, are made of rock or gas, and some have moons or rings.
Answer:
C
Explanation:
there are planets made of ice, rock and gas
All the planets have atmospheres, are made of rock of gas, and some have moons or rings.
• It is to be noted that in the solar system every planet exhibits an atmosphere of one kind or another. It can range from tenuous and thin like of mercury to the incredibly powerful and dense like that of the gas giants.
• The inner planets of the solar system, that is, the Earth, Mercury, Venus and Mars are made of rock, while the giant planets are not solid, they are mainly formed of hydrogen and helium. They are also known as gas giants.
• All the planets have moons except Venus and Mercury, and Saturn possess rings also.
Thus, the correct answer is option D.

Sarah and Thomas are thinking about having kids. They are concerned that because Thomas’s father was diagnosed with cystic fibrosis last year, it could run in the family. Cystic fibrosis is a recessive genetic disorder which affects the respiratory system. Both Thomas and Sarah get tested for the recessive allele (f), with the results indicating that they are each carriers of the disorder (a genotype of Ff).
Is it possible for Sarah and Thomas to develop cystic fibrosis?
It is not possible for Sarah and Thomas to develop cystic fibrosis but it would be possible for one of their children to inherit it. Both Sarah and Thomas are heterozygous and in a heterozygous pair of alleles the dominant allele is the one that will present. Because Sarah and Thomas both have the heterozygous allele combination Ff they are carriers which means that they will not experience symptoms of cystic fibrosis but they could pass cystic fibrosis onto one of their children.
Four substances are important for both photosynthesis and cellular respiration: oxygen, glucose, carbon dioxide, and water. What is the best explanation for how for both processes use these substances?
1.) both produce atp at some point
2.) both make glucose at some point
3.) both require oxygen gas at some point
4.)both include the keens cycle at some point
Answer:
The answer is 4, I got this correct on a Plato test on edmentum
Explanation:
Photosynthesis and cellular respiration are the metabolic processes, in which organisms gain energy from the metabolization of oxygen, glucose, carbon dioxide, and water.
The correct answer is:
Option A. both produce ATP at some point
Photosynthesis is the process of producing glucose and evolving oxygen, whereas cellular respiration is the process of breaking glucose to yield energy, such as:
In photosynthesis, the light-independent reactions or Calvin cycle involves the generation of ATP and NADPH. In cellular respiration, Kreb's cycle is involved in the generation of ATP and NADH, which then enter the electron transport chain.Thus, the process has similar raw materials that are metabolized to generate ATP at some point.
Therefore, option A is correct.

Decide whether the scale factor will produce an enlargement or a reduction. Scale Factor = 5/2. Enlargement Enlargement Reduction
Answer:
Enlargement
Explanation:
Dilation is the enlargement or the reduction in the size of an object.
Enlargement is increase in size of an object. A figure is said to be enlarge if it is larger than the original figure.
Reduction is the decrease in size of an object. A figure is said to be reduced if it is smaller than the original figure.
The scale factor determines if it is either an enlargement or a reduction. If the scale factor is less than one then it is a reduction whereas if the scale factor is greater than 1 it is an enlargement.
Since it is a scale factor of 5/2, it is an enlargement.

Why did the recessive trait for shortness come back in the second generation of Mendel's cross of tall and short plants?
Answer:
Mendel called the visible form the dominant trait and the hidden form the recessive trait. In the second generation, after plants were allowed to self-fertilize (pollinate themselves), the hidden form of the trait reappeared in a minority of the plants.
Viruses, such as influenza, are often spread through droplets made when infected people cough, sneeze, or talk. After a virus infects a new host, it begins to reproduce. Which statement about viral reproduction is
correct?
A virus can only use a host to reproduce if the host cell lacks a cell membrane.
O A virus must complete interphase before entering mitosis.
A virus depends on the host to reproduce, because the vvirusvirus does not contain DNA or RNA.
A virus cannot reproduce on its own and depends on the host cell
Answer:
C
Explanation:
The small living organism which has the outer protein layer and inner genetic material is called a virus. These viruses infect animals and plants both.
A virus can have any of the following as a genetic material:-
RNADNAThe virus can infect the host and take over his genome to replicate his own genetic material. This genetic material has the sequence which causes the infected protein and the infect the host.
Hence, the suitable answer to this question is D, that is:-a virus cannot reproduce on its own and depends on the host cell.

True or False: Blood sugar is at its highest during fasting.
Answer:
True, fasting blood sugar levels are generally higher in the early morning due to the increase hormonal activity during the night, then tend to decrease to more normal levels during the day.
Explanation:
How does sugar cross the cell membrane to get into a cell
Answer:
Molecules, like sugars, reach the carrier proteins in the membrane by diffusion and are then moved across the membrane from a region of high concentration to a region of low concentration.

If one parent has type B blood and the other type O blood what percentage of the child's blood will be B, O, A?
Answer:
If one parent has blood type B and the other parent has blood type O, the percentage of the blood type of the offspring will depend on the genotype of the parent with blood type B.
Explanation:
Knowing the blood type of the offspring of the cross between parents with blood type B and O raises two possible scenarios, depending on whether the genotype of the parent (type B) is B|B or B|O.
Blood type is an inherited trait and is characterized by the presence or absence of surface antigens A and B in the red blood cells, which genetically behave as co-dominant traits.
Blood type A contains antigen A and its genotype can be A|A or A|O. Blood type B contains the B antigen, whose genotype can be B|B or B|O. Blood type AB contains both antigens and a single A|B genotypic expression. Type O blood lacks surface antigens, and is the recessive trait so its genotype is O|O.Scenario 1: Parent with genotype B|B.
In this case, knowing that the genotype for type O is always O|O, all offspring would be of blood type B, genotype B|O.
B|B X O|O
Alleles B B
O B|O B|O
O B|O B|O
100% of the offspring would be of blood type B.
Scenario 2: Parent with genotype B|O.
In this case, 50% of the offspring will have blood type O and 50% B.
B|O X O|O
Alleles B O
O B|O O|O
O B|O O|O
In no scenario would offspring of blood type A be possible.
