Over various spans of time, human populations have increased, decreased, or remained the same, and at both global and local levels. Which statement best explains this observation?
Answer:
C. Like other populations, the human population is affected by a variety of factors in the environment
Note: The options are found in the attachment below
Explanation:
Factors that affect population in the natural world include; availability of food, water, shelter, space, competition for resources, predation, as well as disease.
These factors also affect human population resulting in an increase, decrease or stability in population.
Regarding decrease in population, factors like competition for scarce resources has resulted in wars which greatly reduced human population. Also disease outbreaks, droughts, famines, etc have resulted in decrease in population.
Availability of food, water, shelter and space on the other hand makes for an increase in population by increasing the birth rate, reducing competition and bringing stability.
In some other instances, overtime, there is a balance between birth and death rate, so human population will remain relatively unchanged at these times.

Examples of ovoviviparous animal
Answer:
sharks, rays, snakes, fishes, and insects
Explanation:
These ovoviviparous animals produce eggs, but instead of laying eggs, eggs develop inside the mother's body. The eggs are laid in the mother. After rocking, they stay in the mother for a while and feed there. Then the young are born live.
Ovoviparity is, therefore, a mixture of oviparous (animals that lay eggs) and viviparous (animals that develop in the mother’s body).

What is an IQ?
IQ stands for Intelligence Quotient and is a measure of cognitive abilities and intellectual potential. It is determined through standardized tests that assess various cognitive skills, including problem-solving, memory, and analytical thinking.
The average IQ score is set at 100, with scores ranging from 70 to 130 considered to be within the normal range. Scores below 70 indicate varying degrees of intellectual disability, while scores above 130 suggest above-average intelligence.
While IQ scores can provide insight into a person's cognitive abilities, they do not account for other factors, such as emotional intelligence or creativity, that may contribute to overall success in life. It is essential to recognize that IQ tests have limitations and should not be used to label individuals or limit their potential.
This range is considered to be a mild to moderate intellectual disability, indicating limitations in adaptive functioning and potential need for support in daily life activities.
