p₀=0.5, q₀ = 0.5.// p₅=0.86, q₅ = 0.14.// p₅² = 0.74, 2pq₅ = 0.24, q₅² = 0.02. // 1062 Black individuals DD, 344 Black, 29 White individuals dd.
Note: Due to technical problems, in the attached files you will find the complete explanation.
1) Phenotype frequencies
⇒ F(white) = 0.02
⇒ F(black) ≅ 0.98
2) Allele Frequencies
⇒ f₀(D) = p = 0.5
⇒ f₀(d) = q = 0.5
⇒ f₅(D) = p = 0.86
⇒ f₅(d) = q = 0.14
3) Genotypic Frequencies
⇒ F₅(DD) = p² ≅ 0.74
⇒ F₅(Dd) = 2pq = 0.24
⇒ F₅(dd) = q² ≅ 0.02
4) Number of individuals
⇒ DD Black individuals → ≅ 1062
⇒ Dd Black individuals → ≅ 344
⇒ dd White individuals → ≅ 29

Why do humans need more potent pesticides over time?
A. Because the target population soon develops a resistance to the chemical
B. Because pesticide salesmen need to make more money
C. Because plants begin to eat pesticides
D. Because the explosive growth of the human population places increased demands on current farmers
Answer:
A.
Explanation:
Pesticides are designed to kill a specific target population, such as insects or weeds. however, over time the target population begins to develop a resistance to the chemical, making the pesticide less effective. In order to combat this, farmers need to use more potent pesticides.

What is the scientific evidence for the creation of humans by a deity?
Answer:
Here is the scientific proof that God exists. Look at the universe. Look at humans, animals, plants, and every living thing. How did these things become alive? Did they just exist out of nowhere? God created them. You simply can't argue that everything just existed. Everything has a creator. 0+0+0 cannot ever become 1. God is the only thing that exists without a creator, because God is the only creator who made everything. Look at the insane complexity of life. For example, look at humans. We are the most complex thing alive. We are made perfectly with intelligence that onbody on this earth can ever even come close to. Our little minds can only do so much. God is the one and only who can create life. Can we ever make something become alive? Obviously no. If the whole world would come together we wouldn't be able to make a single living fly..

Plants are autotrophic organisms, because they make their own food. Therefore, option (B) is correct.
What are autotrophic organisms?An autotrophic organism is an organism that is able to produce its own food using energy from an external source, such as sunlight or inorganic chemical reactions. Autotrophic organisms are able to sustain themselves without relying on organic matter from other sources, and they play a vital role in many ecosystems as producers.
There are two main types of autotrophic organisms: photosynthesizers and chemosynthesizers. Photosynthesizers, such as plants and algae, use sunlight as an energy source to convert carbon dioxide and water into glucose through the process of photosynthesis. Chemosynthesizers, such as certain bacteria and archaea, use inorganic chemical reactions, such as the oxidation of sulfur or methane, as an energy source to produce organic compounds.
Autotrophic organisms are important because they form the base of many food chains, providing energy and nutrients for other organisms. They also play a key role in regulating the levels of carbon dioxide and oxygen in the atmosphere.

True or False? When there is a solar eclipse, everyone in the world can see it
happening.
Answer:
i think it is true
Explanation:
Everyone in the contiguous United States, in fact, everyone in North America plus parts of South America, Africa, and Europe will see at least a partial solar eclipse, while the thin path of totality will pass through portions of 14 states.
Answer:
I belive it's false.
Explanation:
Acording to NASA's spaceplace website, Getting a chance to see a total solar eclipse is rare. The Moon's shadow on Earth isn't very big, so only a small portion of places on Earth will see it. ( which includes everyone in North America plus parts of South America, Africa, and Europe will see at least a partial solar eclipse, while the thin path of totality will pass through portions of 14 states)
Also Fun Fact:A total eclipse occurs when the dark silhouette of the Moon completely obscures the intensely bright light of the Sun, allowing the much fainter solar corona to be visible. During any one eclipse, totality occurs at best only in a narrow track on the surface of Earth. This narrow track is called the path of totality. (Credit: NASA )
How did pasteur and Tyndall finally settle the Spontaneous Generation Controversy?
Pasteur and Tyndall finally settled the Spontaneous Generation Controversy with the experiments performed that disproved the theory.
What was the Spontaneous Generation Controversy?This was a theory that stated that life would spontaneously arise, as an attempt to explain the fungi that would grow on food and the appearance of fly larvae in meat, since the existence of bacteria was not known at the time. Pasteur and Tyndall finally disproved this theory by showing that these things do not occur when the food is isolated from the open air.
Therefore, we can confirm that through their experiments which showed that without contact with the open air, life does not arise from leftover food, Pasteur and Tyndall proved that more is needed for life to arise.
