The statements that correctly describe gestation are: the normal period of gestation is about 40 weeks; the stages of this process include: zygote, blastocyst, embryo, and fetus; and changes to the form of the embryo come from differentiation and growth.
The gestation period in humans lasts about 40 weeks and comprises different stages and processes from conception until birth. The main stages of this process include:
Zygote: Fertilized ovum.Blastocyst: Cluster of cells that is the result of the zygote going through cell division.Embryo: Unborn human that is still developing, usually before the 8th week of gestation.Fetus: Unborn human in development after the 8th week of gestation.Moreover, this process implies differentiation as cells specialize for specific functions, for example, muscle cells or nerve cells, and growth as the number of cells increases and therefore the embryo or fetus increases in size.

Answer:
Many different types of cells make up the human body. Therefore, it is important for cells to differentiate to form different types of tissue. The tissue can then combine to form different organs and systems that carry out specialized functions for the human body.

Explain what TWO forces cause Earth’s water to bulge?
Answer:
Gravity and inertia act in opposition on the Earth's oceans, creating tidal bulges on opposite sites of the planet. On the “near” side of the Earth (the side facing the moon), the gravitational force of the moon pulls the ocean's waters toward it, creating one bulge.

Which statement is true about the energy level of solids?
A.) Solids have more energy than water
B.) Solids have more energy than plasma
C.) Solids have the most amount of energy
D.) Solids have the least amount of energy
Answer:
The answer is D.) Solids have the least amount of energy
Explanation:
Because in a solid, particles are packed tightly together so they don't move much. The electrons of each atom are constantly in motion, so the atoms have a small vibration, but they are fixed in their position. Because of this, particles in a solid have very low kinetic energy.

(IV and DV)
Answer:
An example of a scientific investigation design that uses independent variable and dependent variable in its design is a research that seek to find out the effect of two different fertilizers on the growth of a tuber crop (yam). The independent variable in this case is the type of fertilizer used while the dependent variable is the corresponding growth of the tuber crop. In a research set up, the independent variable is the variable that cause a change in the dependent variable.

A rise in __________ released from the sarcoplasmic reticulum allows actin to bind to myosin and cause a contraction, which requires __________ energy.
A rise in CALCIUM released from the sarcoplasmic reticulum allows actin to bind to myosin and cause a contraction, which requires ATP energy. ATP is the energy coin of the cell.
Adenosine triphosphate (ATP) is the energy coin that cells use to carry out many metabolic reactions (e.g., reproduction, motion, differentiation, etc).
The sarcoplasmic reticulum is an organelle located inside muscle cells similar to the smooth endoplasmic reticulum.
This organelle (sarcoplasmic reticulum) acts to store calcium which is required during muscle contraction.

The most likely conclusion that can be made for the change in flower color is that genetic factors caused the differences in flower color.
According to this question, three plants are grown in the same environmental conditions with equal sunlight, water, and space to grow.
However, despite the uniformity in the environmental conditions received by each plant, one plant grew to have a purple flower while the other two grew white flowers.
This difference in flower color is likely caused by the inherent genetic factors of each plant rather than environmental factors because they were treated the same.

A single base substitution mutation is likely to have a less deleterious effect when the base change exhibits which of the following results
A single base substitution mutation will be the least likely to cause a deleterious effect when the base change produces the same amino acid as the original.
What is a silent mutation?This scenario is what we call a silent mutation. What this means is that the mutation is almost undetectable due to its not affecting the protein that it will help to form.This is possible thanks to how the genetic code operates, different codons are able to code for the same amino acid.Therefore, there are mutations that do not affect the amino acid or the protein.Therefore, we can confirm that a mutation will have no negative effects if it is a silent mutation, meaning that the substitution of a base pair happens to code for the same amino acid as the original.
