The correct answer is primary growth
Answer:
<em>a. Cross-sectional study</em>
Explanation:
A cross-sectional analysis <em>includes at one particular point in time looking at data from a population.</em> Participants are chosen based on specific variables of interest in this type of study.
For developmental psychology, cross-sectional experiments are often used, but this approach is also used in many other fields, including social science and education.
Answer: Option B (True)
Explanation: The statement can only occur in different populations of the same organism. The two growth strategies happens in different modes.
Firstly, logistic growth occurs when the resources available in the habitat (i.e organism’s niche) are limited to satisfy the whole population and this allows the organisms of the same species to grow rapidly until it reaches the point the resources can circulate, the carrying capacity.
While exponential growth occurs when there's abundance of resources for the population and allows growth of population beyond the carrying capacity, which results to overshoot of population in later stage of growth.
Secondly, in logistic growth population rarely crash but in exponential growth, population crashes due to mortality (often by predation, disease outbreak and etc) when there's overshoot of population beyond the carrying capacity.
Note: Population refers to the total number of organisms of the same species inhabiting a geographical area at a particular time.
Answer:
The correct answer is - option B. Interphase is made up of the G1, S, and G2 phase and is the portion of the cell cycle where cellular contents are duplicated.
Explanation:
Interphase is the phase in the cell cycle in which the cell prepares to go under cell division by growing in size, replicating, or duplicate the cellular contents like DNA or genetic material and prepare for mitosis. Interphase includes the substages G1, S, and G2 phases.
It is known as the longest stage of the cell cycle as it includes four substages that takes time due to growing the cell, double the content and make the cell ready to go under division.
Meiosis.
Meiosis results in four cells of the original, each with a halved amount of chromosomes, you could say.
