C. Statements 2 and 3
D. Statements 3 and 4
Answer:
The answer is A.

Why could reproductive cells from an apple tree and a banana tree never combine to form an offspring? Use data and scientific reasoning to construct an explanation.
Answer:
Difference in chromosome number.
Explanation:
The reproductive cells from an apple tree and a banana tree never combine to form an offspring because of the difference of species. There is different number of chromosomes in the both apple and banana tree. There are 17 number of chromosomes in apple whereas 33 number of chromosomes in banana tree so due to this difference in the chromosome number apple and banana tree can produce offspring due to combination.
The process of formation of new offspring from the parents is called reproduction. Reproduction help to ensure the continuity of species generation after generation. There are two types of reproduction, these are as follows:-
SexualAsexual.Reproduction required the gametes of the same species for fusion. The mating of the two gametes is known as fertilization.
According to the question, the apple tree and a banana tree never combine to form offspring because of the gamete difference, These gametes are from different species.
Hence, they cannot reproduce.

As part of the greenhouse effect, Earth’s surface radiates heat back into the atmosphere and the atmosphere absorbs this heat. Why do areas near the equator generally radiate more energy back into the atmosphere than areas near the poles?
Areas near the equator have more clouds in the atmosphere than areas near the poles.
Areas near the equator receive more incoming solar energy than areas near the poles.
The greenhouse effect only occurs near the equator.
The greenhouse effect only occurs near the poles.
Answer:
The correct answer is B. Areas near the equator receive more incoming solar energy than areas near the poles.
Explanation:
The equator is located in the center of the planet from North to South, this location cause this zone and nearby zones to receiver more solar energy than areas near the poles. This occurs because the natural tilt of Earth makes sun rays directly hit the equator all the time of the year, while areas in the poles are not hit directly and the exposition to sunlight varies with the seasons of the years. This explains why in the equator the temperatures are higher than in the poles. Besides this, the difference in radiation received makes areas in the equator radiate more energy back due to global warming gases, and the global warming phenomenon.
Areas near the equator receive more incoming solar energy than areas near the poles.

Level
B
Level
A
Producers
The sun
O Level B
O Level D
Answer:
The answer is the sun.
Explanation:
Level a represents the producers which you can tell, by their name, that they make their food. Producers are mainly comprised of the plants of our world. They get their energy from the sun and through photosynthesis, they turn it into energy.
By the way, B would be primary consumers which are the herbivores, C are the secondary consumers which include us people, and D are the decomposers, which include worms.
Level A represents the producers which make their own food and are mainly comprised of the plants of our world. They gain energy from the sun and through the process of photosynthesis.
The energy for use by organisms in level A originally comes from sun. Thus the correct option is A.
What is photosynthesis?
The process through which green plants and some other organisms use sunlight to make foods from carbon dioxide and water. Photosynthesis in plants generally involves the green colour pigment chlorophyll and generates oxygen as a byproduct.
Whereas, B would be primary consumers which are the herbivores, C are the secondary consumers that include omnivorous, and D are the decomposers, which include worms.

Strontium-90 has a half life of 29 years, how much strontium-90 is left from the Chicago pile reactor that was active around 87 years ago.
Answer:
The answer is below
Explanation:
The half life of a substance is the time required by that substance to reduce to half of its initial value. The half life is calculated using the formula:
[tex]N(t)=N_o(\frac{1}{2} )^\frac{t}{t_\frac{1}{2} } \\\\where\ N(t)=quantity\ of\ substance \ remaining, N_o=initial\ quantity\\of\ substance, t=time\ and \ t_\frac{1}{2}=half\ life\ of\ substance[/tex]
Given that t = 87 years, half life = 29 years, therefore the quantity of strontium-90 left is:
[tex]N(t)=N_o(\frac{1}{2} )^\frac{87}{29} \\\\N(t)=N_o(\frac{1}{2} )^\frac{t}{t_\frac{1}{2} } \\\\N(t)=N_o(\frac{1}{2} )^3\\\\N(t)=\frac{1}{8} N_o[/tex]
That is one-eight of Strontium 90 would be left after 87 years
