What happens in the process of gravitational condensation?
In the process of gravitational condensation, an object decreases in size due to the collision of materials.
When two materials collide, an object shrinks in size. Materials from solar nebulae are used to create gas particles. Materials from the solar nebula are converted into solid particles.
The force that pulls objects with mass toward the Earth and attracts them there is known as gravitational force. It should be understood that when heated water transforms from a liquid condition to a gaseous state, the size will decrease.
We observe that the cohesive forces of fluids that cause droplets to coalesce and bond together, as well as the quantum condensation of a BEC, are comparable to the effects of gravity on matter.

Which of the answer choices is an example of negative feedback altering homeostatic control?
a. A person with a bacterial infection runs a fever and his body temperatures rises and stays elevated for several days.
b. The concentration of salt in a person's urine increases after that person eats a large bag of salty chips.
c. A person's heart rate remains elevated over the course of a long run.
d. The production of oxytocin (a hormone) increases in a pregnant woman's body as oxytocin levels in her body rise.
A negative feedback altering homeostatic control is option B: The concentration of salt in a person's urine increases after that person eats a large bag of salty chips.
The ability of the body to maintain its normal state in the face of changes in the external environment is known as homeostasis. The ion concentration can be controlled via homeostasis. The desire to excrete salt through urine also grows as the body absorbs salt from eating chips. Therefore, negative feedback loops that change homeostasis are used to maintain the salt's ionic concentration. Therefore, option B marks the correct choice.
The inclusion of negative feedback loops helps to maintain homeostasis. These loops behave in the opposite direction from the stimuli that causes them. If the body temperature is high, for instance, the negative feedback loop will work to lower it toward the set point, or the desired value.

Another type of digestion in the stomach produces physical changes. Describe the actions of the stomach that lead to these physical changes.
Answer:
When food is physically changed, mechanical digestion occurs. Food is broken into smaller parts and mixes continually with enzymes and other gastric juices. Mechanical digestion occurs in the mouth, stomach, and small intestine. Food is chemically changed in digestion when new, smaller substances are formed. These chemical changes are examples of chemical digestion. Chemical digestion begins in the mouth when enzymes in saliva begin to break down carbohydrates. Most chemical changes in digestion occur in the small intestine. Large molecules of food are broken down into smaller molecules that can be absorbed by our cells. Carbohydrates, proteins, and fats are broken down in different parts of the digestive system using different kinds of enzymes. Different kinds of small molecules are formed by these processes.

3.RNA is single stranded while DNA is double stranded .
What is the structure and function of DNA?
The organic components known as nucleic acids can be found in the form of DNA or RNA in all living things. These nitrogenous bases, sugar molecules, and phosphate groups are joined by various bonds in a series of sequences to form these nucleic acids. The fundamental genetic make-up of our body is defined by the DNA structure. In actuality, it describes the genetic composition of almost all life on earth. This holds true for viruses as well because the majority of these organisms have either RNA or DNA as part of their genetic makeup. As an illustration, some viruses may have DNA as their genetic material, while others may have RNA. RNA is present in the Human Immunodeficiency Virus (HIV), which after attaching to the host cell, transforms into DNA.
So, the DNA is double stranded while RNA is single stranded.

In a particular strain of mice. Fur coat color is either black or brown, where black
(B) is dominant to brown (b). A homozygous dominant mouse mates a mouse with
brown fur.
What are the genotypes of the two individuals?
What proportion of their offspring will have black fur?
BB or Bb is the genotype of the two individuals. More than 90% proportion of their offspring will have black fur.
Black mice must have at least one B allele since the color is dominant. Either BB or Bb could be their genotype.
Because every offspring will have at least one dominant allele for black fur, which will outweigh any allele for brown fur, it is expected that all offspring will have black fur, so the proportion will be more than 90%.
The mix of genes found in the sex cells or gametes (ova and sperm) that were used in a child's conception determines the genotype of that child. From each parent came one sex cell. The gene for each attribute is often only present in one copy in sex cells.

13) Atoms bond with other atoms when they need to fill their shell
Atoms bond with other atoms when they need to fill their shell is true .
What is atom ?When two atoms share a pair of electrons, covalent bonding results. In order to increase their stability, which is attained by forming a complete electron shell, atoms will covalently connect with one another. Atoms can stabilize themselves by filling up their outer electron shell by sharing their outermost (valence) electrons.
Atoms, which are very little particles of matter, are what define a chemical element specifically. The core nucleus of an atom is surrounded by one or more negatively charged electrons.
ATOM BOND :Whatever atoms the shared electrons originally belonged to or how many electrons are involved, a bond is simply the sharing of electrons between two or more atoms to satisfy their demand for an unoccupied final shell.
