The answer is *C. is a slow, gradual change over time*.
Answer: conception and birth
Explanation:
Gestation is the period between conception (when the female sex cell get fertilized by the male sex cell) and birth (when the fertilized egg has become matured for delivery).
It varies from one animal to another. For example: In humans, it is 9 months; In hen, it is 21 days.
Answer:
Rhizobium is a bacterium that has positive effects on plant growth. Different strains display a wide range of effectiveness, from a little positive effect to a massive one. The strains used in the study did not show a positive effect promoting plant growth, so we could say that they ARE NOT Rhizobium strains and need to be properly identified.
Explanation:
As the wolves with short hair decreases (because the environment does not encourage their survival), there will be less competition for the food that both would need. The long haired wolf even with a recessive gene, would increase in number.
A might be true but the hair length by itself will not cause the extinction of the entire wolf population.
C is simply not true. Your givens tell you that the long hair are more likely to survive.
B is the answer, for the reason given above.
Two types of population growth patterns may occur depending on specific environmental conditions: An exponential growth pattern (J curve) occurs in an ideal, unlimited environment. A logistic growth pattern (S curve) occurs when environmental pressures slow the rate of growth.
