Answer:The answer is A: conduct a controlled experiment

Explanation:  Different scientific questions and predictions require different types of scientific investigations. Some questions, such as questions involving how one factor affects an organism or event, can be answered through controlled experiments. Other questions can be answered through collecting specimens, building models, and/or making observations.

Answer:

Option A is the correct answer. To conduct a controlled experiment would be the best choice for Maria to test her prediction.

Explanation:

A controlled experiment can be described as an test in which one of the test models is kept constant for a variable, while in other experimental models, a change is made for testing the variable.

It would be best for Maria to conduct a controlled experiment. In the control model, Maria should keep light as constant whereas in other experimental models she should increase and decrease the quality of light to test her prediction. She should then compare her experimental results with the control model to deduce the results.

gizmo_the_mogwai [7]
Mitosis is a type of cell division that takes place in the somatic cells where two daughter cells are formed with the same number of chromosomes as the parent (diploid 2n). Meiosis is a type of cell division that takes place in the sex cells where four daughter cells are formed with half the number of chromosomes as the parent (haploid, n). In this case, if the gametes were formed by mitosis then it means they would have a diploid (2n) number of chromosomes.

luda_lava [24]

Answer:

A flat sheet of connective tissue that extends beyond the muscle fibers to attach the muscle to bone is a TENDON.

Explanation:

Tendon can be described as a fibrous connective tissue which functions mainly to attach muscles to bones hence, playing a major role in the movement of the bone or structure. Tendons also function to connect muscles to other structures like the eye ball.

Contrary to the tendons, ligaments are also fibrous connective tissues which are involved in the attachment of bone to bone. Hence, ligaments play major role in holding the structures and keeping them stable.
