<h2>Answer:</h2>

The correct answer is option B which is when Earth is on perihelion, it is the beginning of summer.

<h3>Explanation:</h3>
  • Perihelion and aphelion are Greek words. In Greek hellion means the sun and peri means close while ephe means far.
  • So t perihelion which is normally two weeks after December it shows the starting of summers.
  • Some areas of earth begin to come in front of sun due to which the temperature of these areas start rising.

Define crop rotation.
Juli2301 [7.4K]

Answer:

Crop rotation is the method of growing a series of different types of crops in the same area across a sequence of growing seasons (China does this). It reduces dependence on just one type of nutrients, it also helps control pests and weeds by the plants developing a resistance all at once.

3. Predict: Based on your hypothesis, predict how changing the rabbit population will affect the other organisms at first. Write
Damm [24]

Answer: as the predator’s population goes up, the preys will go down, and as the prey’s goes up, the predators will go up. They are basically the opposite of each other.

Explanation: I can’t really tell what your question is. However if there are more prey to eat, then the number of predators will grow because they have more food. However, once there’s too many predators, the number of prey will drop which lowers the amount of food.

Why can carbon form very large molecules?
malfutka [58]

Answer;

(c) It can bond with other carbon atoms that are bonded to other molecules

Explaation;

-Carbon is the only element that can form so many different compounds because each carbon atom can form four chemical bonds to other atoms, and because the carbon atom is just the right, small size to fit in comfortably as parts of very large molecules.

-Carbon chains can bond with carbon rings to form very large, complex molecules. These large molecules can be made of many small molecules that are bonded together.

6. A scientist measures the circumference of acorns in a population of oak trees
melisa1 [442]

Answer:

6. 2 cm

8. Greater than 2 cm and less than 2 cm

Explanation:

Complete Question

6. A scientist measures the circumference of acorns in a population of oak trees and discovers that the most common circumference is 2 cm. What would you expect the most common circumference(s) to be after 10 generations of stabilizing selection?

-2 cm

-Greater than 2 cm or less than 2 cm

-Greater than 2 cm and less than 2 cm

-Can't tell from the information given

8. Refer to question 6, but this time answer what you would expect after 10

generations of directional selection.

-2 cm

-Greater than 2 cm or less than 2 cm

-Greater than 2 cm and less than 2 cm

-Can't tell from the information given

Solution -

6. In an stabilizing selection, the average trait of a given population is favored over extreme values. Hence, it can be said that one specific trait is over presented in a given population. For example – uniform human birth weight, number of eggs a bird lay etc.  

Here in this case if most common circumference is 2 cm , then the tree population will try to have this trait as a stabilizing trait.  

Thus, option A is correct

8. In a  directional selection, the genetic variation decreases as per the environmental change. And hence the average trait will not be selected. Instead traits either higher or lower the average values will be preferred.  

Thus, option C is correct
