Over time, as oxygen levels decrease, CO2 levels increase. Respiration is correct as it uses oxygen as a reactant and releases CO2 as a byproduct.
Shortly after gastrulation, the body and organs of the embryo begin to form. This process is called <u>embryogenesis.</u>
<u></u>
- The process by which an embryo transforms into a fetus is known as embryogenesis.
- The three germ layers that eventually give rise to the various organs in the animal body are formed as a result of gastrulation.
- Embryogenesis is the name of this process. As a result of differentiation, organs emerge from the germ layers.
- The process of creating and growing an embryo from a zygote (zygotic embryogenesis) or a somatic cell is known as embryogenesis (somatic embryogenesis).
- An incredibly well-organized series of cell division, expansion, and differentiation takes place during embryo development.

Explanation: This type of data can be expressed and measured numerically.
The question is about a test cross. Definition of a test cross: Generally a cross involving a homozygous recessive individual. When a single trait is being studies, a test cross is a cross between an individual with the dominant phenotype but of unknown genotype (homozygous or heterozygous) with a homozygous recessive individual. If the unknown is heterozygous, then approximately 50% of the offspring should display the recessive phenotype. If the individual is homozygous all the progeny will have the dominant phenotype. James' suggestion to use show the result of the two possible crosses with a Punnet square is a great suggestion.
