In the natural world, limiting factors like the availability of food, water, shelter and space can change animal and plant populations. Other limiting factors, like competition for resources, predation and disease can also impact populations.
Answer: The angle of refraction is 32°
Explanation:
By snell law, we have that:
n₁*sen(θ₁) = n₂*sen(θ₂)
Where n₁ = 1.5
n₂ = 2.0
θ₁ = 45°.
then we want to find the angle of refraction.
1.5*sin(45°) = 2*sin(x)
x = Asin(1.5*sin(45°)/2) = 32°
Answer:
Disease and Famine
Explanation:
If there is a disease that affects a type of plant, having other types of crops to rely on could save one from starvation. Also, only planting one crop in an area can change the pH and nitrogen levels in negative ways, so that eventually no plants can grow there. Not to mention the obvious balanced diet needed for a healthy body.
Mitosis is cell division in to daughter cells with the same chromosome number as the parent cell
Answer: No
Explanation: if a nucleic acid contains uracil then it is not DNA it's an RNA. Uracil is the basic nitrogenous base of RNA. DNA does not have Uracil in its structure. It contains thiamine instead of Uracil. So the answer is NO.
