Answer:
Buffers are chemicals that help a liquid resist changing its acidic properties when other chemicals are added that will normally cause a change in these properties.
Answer:
buffers are chemicals that help a liquid resist changing its acidic properties. the reason they are important to cells is because buffers maintain the right pH of a liquid.

According to Kepler's second law of motion, which statement describes the area
swept out py a line between a planet and the sun?
It is constant if the planet moves at a constant speed.
O It increases as the planet moves away from the sun.
O It is constant for equal times.
OIt increases as the planet approaches the sun.
Answer: It is constant for equal times
Explanation: Just did the assignment
According to Kepler's second law of motion it is constant for equal times. The correct option is C.
What is Kepler's law?Kepler's laws of planetary motion, published between 1609 and 1619 by Johannes Kepler, characterize the orbits of planets around the Sun.
The speed of a planet in an elliptical orbit around the Sun is described by Kepler's second law of planetary motion.
It states that a line drawn among both the Sun as well as the planet shuffles equivalent regions in equal amounts of time.
As a result, the planet's speed increases as it approaches the Sun and declines as it fades away from it.
Kepler's laws of planetary motion represent a watershed moment in the transformation from geocentrism to heliocentrism.
They establish the first quantitative link among the planets, together with Earth. They also represent a time when the important questions of the day were changing.
Thus, the correct option is C.

what percentage of genetic information is passed on from parents to their offspring
Answer:
50% from each parent
Explanation:
The percentage of genetic information passed on from parents to their offspring is 50% from each parent, for a total of 100%.
What is the percentage of genetic information?Approximately 50% of genetic information is passed on from each biological parent to their offspring. This occurs through the combination of genetic material during fertilization, where half of the offspring's genetic material comes from the mother and the other half from the father.
However, the exact percentage of genetic information passed on can vary due to factors such as genetic mutations and recombination during meiosis.
This occurs through the process of sexual reproduction, where each parent contributes one gamete (sperm or egg) containing half of their genetic information.
When the sperm and egg combine during fertilization, they form a zygote with a complete set of genetic information (100%), half from each parent.

D. The mitotic spindle attaches to chromosomes. Microtubules organize the chromosomes. The nuclear membrane dissolves.
Mitosis can be defined as a type of cell division or duplication through which a single parent cell produces two (2) genetically identical daughter cells.
During mitotic division, the two (2) genetically identical daughter cells produced by a single parent cell usually have the same number of chromosomes as their parent cell; this process is referred to as duplication division.
Furthermore, the following events take place during mitotic division in living organisms:

which type of transport would be required for the solute molecules to move against the concetration gradient?
Answer:
Active Transport
Explanation:
active transport
During active transport, substances move against the concentration gradient, from an area of low concentration to an area of high concentration. This process is “active” because it requires the use of energy (usually in the form of ATP). It is the opposite of passive transport.
the __________ girdle attaches the upper limb to the axial skeleton.
Answer:
pectoral
Explanation:
Each upper limb is connected to the axial skeleton by the pectoral girdle, which is made up of the clavicle and the scapula.
What is axial skeleton?The clavicles and scapulae make up the pectoral or shoulder girdle. The upper limb bones are joined to the axial skeleton by the shoulder girdle. Additionally, the muscles that move the shoulders and upper limbs join to these bones.
Your upper limbs are attached to the bones along your body's axis by a pectoral girdle, also known as the shoulder girdle. Your body contains two pectoral girdles.
Therefore, the clavicle and collarbone, which together make up your shoulder, make up the pectoral girdle.

The only way to tell if the red blood cells are crenated is to observe them under a microscope
What is crenation?Crenation is the process of red blood cells becoming misshapen and breaking apart, and this can be seen through the examination of red blood cells under a microscope.
By observing the shape of the red blood cells, it can be determined if they are crenated or not. Additionally, other methods such as hemoglobin analysis or measuring the osmotic fragility of the red blood cells can also be used to determine if crenation has occurred.

Explanation:
First, a three-dimensional stranded structure is assembled, with the amino acids glycine and proline as its principal components. This is not yet collagen but its precursor, procollagen. Procollagen is then modified by the addition of hydroxyl groups to the amino acids proline and lysine.

What the relationship between a glucose molecule and the products it makes during cellular respiration.
Answer:
During cellular respiration, a glucose molecule is gradually broken down into carbon dioxide and water. Along the way, some ATP is produced directly in the reactions that transform glucose. Much more ATP, however, is produced later in a process called oxidative phosphorylation.
During cellular respiration, glucose makes water, carbon dioxide, ATP, lactic acid, and ethanol. In the absence of oxygen, ethanol and lactic acid are formed from the glucose.
What is glycolysis?
Glycolysis is a process in which glucose breaks down inside a cell. Glucose makes pyruvate as an end product in this process. In the presence of oxygen, glucose breaks down into pyruvate and proceeds to the Krebs cycle. In this process, ATP, water, and carbon dioxide are released.
In the absence of oxygen, glucose is converted into lactic acid and ethanol. This is called fermentation and produces only 2 ATP from glucose. This is called anaerobic respiration.
When oxygen is present from glucose, nearly 36-38 ATP are formed. Pyruvate converts into acetyl CoA, and it enters the Krebs cycle. A complete oxidation of glucose takes place in the presence of oxygen.
Hence, in the presence of oxygen, 36-38 ATP is released from glucose, and in the absence of oxygen, lactic acid and ethanol are produced with 2 ATP.
