Answer:

B. is not manipulated and used for comparison

Explanation:A control group is merely a group placed on an experiment for comparing with the experimental group. The control group will receive no treatment and serves as a reference to measure the reactions of the subjects present in the group being tested.

The use of a  control group is necessary for an experiment since the experiment has variables being tested and some other factor may arise in the carrying out of the experiment, that previously was not taken into account. It allows then to eliminate also non-essential variables.

Then researchers can make sure the hypothesis, remaining all variables the same for the tested groups will enable to measure the independent variable and see if this variable is to be held accountable for the results as the outcome of the research.

<span>Neither. You need a nutritionist. Biochemist and food scientists could peripherally be involved by seeing that food is processed in such a way as to preserve the nutritional value of the food. (e.g., seeing that the vitamins are not degraded by processing) and contaminates and bacteria are not introduced.</span>

-describe the 3 steps of embryonic development (cleavage division, gastrulation, organogenesis)
julsineya [31]

Answer:

Cleavage, in embryology, in the first few cell divisions of the zygote. Initially, the zygote separates into the longitudinal axis. The second division is also longitudinal but at 90 degrees on the first plane. The process produces a multicellular embryo. It is an assembling process that divides the seed into developmental regions. Zygote cytoplasm includes chemicals that control gene expression.

Gastrulation is characterized as an early embryonic phase in which the embryo is converted from a one-dimensional layer of epithelial cells to a multilayer, multidimensional structure called the gastrula.

Organogenesis is a process of embryonic development that occurs at the end of gastrulation and lasts until birth. During organogenesis, the three germ layers formed by gastrulation (ectoderm, endoderm, and mesoderm) form the internal organs.

zlopas [31]

Answer:

reactions

Explanation:

Reactions occur when two reactant molecules effectively collide, each having minimum energy and correct orientation. Reactant concentration, the physical state of the reactants, and surface area, temperature, and the presence of a catalyst are the four main factors that affect reaction rate.
