In the cells of most organisms, DNA is contained in the
a
cell wall
b
nucleus
c
ribosomes
d
lysosomes
Answer:
B. Nucleus
Explanation:
DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA). Mitochondria are structures within cells that convert the energy from food into a form that cells can use.
The information in DNA is stored as a code made up of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T). Human DNA consists of about 3 billion bases, and more than 99 percent of those bases are the same in all people

Cells in the body use oxygen for cellular respiration. Select the two sentences that correctly describe cellular respiration.
ATP is produced.
ATP is consumed.
Carbon dioxide is absorbed.
Carbon dioxide is released.
Answer:
ATP is produced
Carbon dioxide is released
The two sentences that correctly describe the process of cellular respiration are as follows:
ATP is produced.Carbon dioxide is released.Thus, the correct options for this question are A and D.
What is Cellular respiration?Cellular respiration may be defined as a biological process through which a form of sugar which is known as Glucose is transferred into energy in the form of ATP in the presence of oxygen. This energy is required to accomplish metabolic activities.
The complete reaction of cellular respiration is as follows:
Glucose + Oxygen → Carbon dioxide + Water + Energy (ATP).With the help of the reaction, it can be determined that glucose and oxygen are utilized while carbon dioxide and energy in the form of ATP are produced as products.
Therefore, ATP is produced and Carbon dioxide is released are the two sentences that correctly describe the process of cellular respiration. Thus, the correct options for this question are A and D.

In one cubic meter of the ocean, photosynthetic plankton produce 80,000 calories of energy each year. How many calories of energy are available in the bodies of the creatures that eat that plankton?
Select one:
a.
80,000
b.
8,000
c.
800
d.
80
8000 calories of energy are available in the bodies of the creatures that eat that plankton. Details about calories can be found below.
How to calculate energy available?In a natural habitat, living organisms feed on one another to derive energy needed for their metabolic activities.
However, only 10% of energy available is transferred to the organism because 90% (most) of the energy is used for the organism's metabolism.
According to this question, in one cubic meter of the ocean, photosynthetic plankton produce 80,000 calories of energy each year.
Therefore, 10/100 × 80,000 calories = 8,000 calories of energy are available in the bodies of the creatures that eat that plankton.

In a process called ____________ , genetic material is exchanged between homologous chromosomes. This occurs during this stage of cell division: ____________ .
In a process called crossing over, genetic material is exchanged between homologous chromosomes. This occurs during the prophase stage of cell division.
What is crossing over?Crossing over is the unique process by which genetic material is exchanged between the non-sister chromatids of homologous chromosomes.
Crossing over occurs in the prophase stage of meiosis and ultimately results in the formation of genetic combinations in offspring that are not present in the parents.
Therefore, the process called crossing over, genetic material is exchanged between homologous chromosomes and it occurs during the prophase stage of cell division.

Which of these statements best explains why Copernicus and Kepler had different views about the solar system?
O They came from different cultures.
O They liked to disagree professionally.
O They had different goals and interests.
O They misinterpreted scientific facts and data.
The best statement that explains why Copernicus and Kepler had different views about the solar system is that they had different goals and interests, which is the third option, as Copernicus and Kepler had different perspectives on the solar system.
Copernicus, a Polish astronomer, was interested in the simplicity and elegance of the universe and sought to find a more accurate model of the solar system. He proposed that the sun, not the earth, was at the center of the solar system, which was a revolutionary idea at the time. On the other hand, Kepler, a German astronomer, was more focused on the mathematical and physical aspects of the solar system and used his observations of the planets to develop the laws of planetary motion.

chromosomes from blood drawn from a five-day-old baby appears to have slight facial deformities and has been diagnosed with an atrial heart defect
Answer:
A congenital heart defect (CHD) is a heart problem that a baby has at birth. It is caused by abnormal formation of the heart during growth in the womb. In most cases, when a baby is born with a congenital heart defect, there is no known reason for it. Some types of congenital heart defects can be linked to an abnormality in the number of a baby’s chromosomes. They may be linked to single gene defects. Or they may be linked to environmental factors. In most cases, there is no clear cause that can be found for the heart defect. They are often thought to be caused by many factors. The factors are usually both genes and the environment. This means that genes from both parents plus unknown environmental factors lead to the problem.
