I know It is c hope is helps!

Answer:

1. Hypothesis:

a supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation

2.Ocean systems:

The ocean is a global, interconnected system that has regions, or basins. Water and ocean life move between these basins and up and down the water column. Ocean water circulates around the globe through ocean currents that are either wind-driven currents or density-driven currents.

3.Proteins:

a class of nitrogenous organic compounds which have large molecules composed of one or more long chains of amino acids and are an essential part of all living organisms, especially as structural components of body tissues such as muscle, hair, etc., and as enzymes and antibodies.

4.Saturated fat molecules:

Saturated fat, a fatty acid in which the hydrocarbon molecules have a hydrogen atom on every carbon and thus are fully hydrogenated. (By way of comparison, the hydrocarbon molecules of unsaturated fats have two carbons that share double or triple bonds and are therefore not completely saturated with hydrogen atoms.)

5.Enzymes:

a substance produced by a living organism which acts as a catalyst to bring about a specific biochemical reaction.

6.Prokaryote:

a microscopic single-celled organism which has neither a distinct nucleus with a membrane nor other specialized organelles, including the bacteria and cyanobacteria.

7.Eukaryote:

an organism consisting of a cell or cells in which the genetic material is DNA in the form of chromosomes contained within a distinct nucleus. Eukaryotes include all living organisms other than the eubacteria and archaea.

8.Hemoglobin:

a red protein responsible for transporting oxygen in the blood of vertebrates. Its molecule comprises four subunits, each containing an iron atom bound to a haem group.

9.Active Transport:

the movement of ions or molecules across a cell membrane into a region of higher concentration, assisted by enzymes and requiring energy.

10.Phospholipids:

a lipid containing a phosphate group in its molecule, e.g. phosphatidylcholine.

11.Facilitated diffusion:

Facilitated diffusion (also known as facilitated transport or passive-mediated transport) is the process of spontaneous passive transport (as opposed to active transport) of molecules or ions across a biological membrane via specific transmembrane integral proteins.

Which statement about development in the embryonic stage of development is true?
creativ13 [48]

Your baby goes through a period of rapid change after conception known as the embryonic stage. The infant is referred to as an embryo at this point. The eyes form between days 21 and 28.

<h3>What is meant by the embryonic stage?</h3>

Your baby goes through a period of rapid change after conception known as the embryonic stage. From the fifth to the tenth week of pregnancy, this phase lasts. The infant is referred to as an embryo at this point. The embryonic stage is when a lot of changes take place.

An embryo exists the first stage of a multicellular organism's development. Embryonic development is the phase of the life cycle that starts right after the male sperm cell fertilizes the female egg cell in sexually reproducing organisms.

The embryo is about the size of a pea at four weeks old. The head is defined by crudely drawn eyes and ears, and tiny bumps serve as the body's arms and legs. The embryo also has a developing nervous system and its head is growing.

Therefore, the correct answer is option d. The eyes form between days 21 and 28.

To learn more about the embryonic stage refer to:
