Are viruses considered to be alive? Why or why not?
Answer:
No
Explanation:
They are not considered alive since they are not made out of cells, they can't keep themselves in a stable state, they don't grow, and they can't make their own energy. Some viruses may be alive if they do have cells but just in general No.
Why do monosaccharide sugars burn faster than polysaccharides?
Answer:
Explanation:
This is because they are simpler molecular structure,with C-H bonds compare to polysaccharides which are aggregate of monosaccharide formed by glycosidic bonds.(covalent bonds) through condensation(This is the loss of OH and H from sugar molecules involved) the differences in strength of the two bonds is the reasons.

please help
A:a low reproductive rate
B:big difference between original and new habitats
C:a strong predator in new habitat
D:great tolerance to a wide range of conditions
Invasive species are defined as organisms that cause economic or ecological harm to the new environment affecting the ecosystem.
The correct answer is:
Option D. great tolerance to a wide range of conditions
Invasive species can be defined as:
1. Invasive species are defined as organisms or species that are potentially harmful to the ecosystem.
2. Invasive species shows great tolerance to a wide range of conditions or harsh environment. Invasive species are more tolerant of higher temperatures than native species and have high chances of survival.
Thus, the correct answer is Option D.

justify the following statement “thinking and new ideas advance science, not just the design of instruments” please help
Answer:
Designing some instruments does help science, but it doesn't advance ideologies of science.
Explanation:
Science is based on theories and laws. Scientists are constantly trying to explain the concepts of the universe by ideas. Sure, instruments do help scientists gather information and such, but ideas and philosophies, theories and laws are the ones that are most important. Without new ideas in science, we would not be able to hypothesize many things, or even develop new instruments.
Answer:

Explanation:
Thinking and new ideas are the main advance in science. It's how new things are created. It is a lot more than just the design of instruments.

Explain cancer in terms of the cell cycle
Answer:
hey mate this is your answer
Explanation:Cancer is unchecked cell growth. Mutations in genes can cause cancer by accelerating cell division rates or inhibiting normal controls on the system, such as cell cycle arrest or programmed cell death. As a mass of cancerous cells grows, it can develop into a tumor.
Cancer is the result of unregulated cell division caused by a breakdown of the processes that govern the cell cycle.
What are oncogenes?A gene that has the potential to cause cancer is known as an oncogene. These genes frequently exhibit mutations or are highly expressed in tumor cells.
When crucial functions are altered and malfunctioning, the majority of healthy cells will die quickly and according to a predetermined schedule.
Uncontrolled cell division brought on by a breakdown in the mechanisms that control the cell cycle results in cancer.
The loss of control is caused by a change in the DNA sequence of a gene that codes for one of the regulatory molecules. Incorrect instructions will cause a protein to malfunction.
Thus, due to unregulated cell cycle, cancer becomes prominent.

Which process results in two identical cells?
meiosis
replication
fertilization
mitosis
Answer:
d
Explanation:
The process that results in two identical cells is known as Mitosis. Thus, the correct option for this question is D.
What is Mitosis?Mitosis may be defined as a type of cell division through which two identical daughter cells are produced from a parental cell. These daughter cells are genetically identical to their parental cells and are mostly diploid in nature.
While the process of meiosis typically produces four daughter cells from a parental cell. These daughter cells are not genetically identical to their parental cells. These cells are haploid in nature.
The process of fertilization may be defined as when two distinctive gametes are fused together in order to produce a zygote. While replication is the duplication or synthesis of genetic material during the S-phase of Interphase.
Therefore, mitosis is the process that results in two identical cells. Thus, the correct option for this question is D.

Most
The students found that pepsin functions best in an acid environment and trypsin functions best in a neutral environment. Based on their
observations, pepsin most likely alds in digestion in which part of the human body?
(5.9 points)
A. Pancreas
B. Intestines
C. Mouth
ID. Stomach
Answer:
D. Stomach
Explanation:
One of the most important digestive enzymes that aids digestion by breaking down of ingested food, most especially proteins is pepsin, which is usually referred to as "stomach enzyme".
Pepsin is found secreted in the stomach.
The pH of the stomach is usually low, between 1.5 to 2 (acidic). This acidic environment of the stomach actually favors this stomach enzyme, as it activated the pepsin to perform it's function.
Based on the observations made by the students, it can be concluded that pepsin aids digestion most in the stomach. It's pH requirement to function optimally matches with the pH of the environment of the stomach.

how would you (in your own words) define carbon footprint in 2 sentances?
Explanation:
the amount of carbon dioxide released into the atmosphere as a result of the activities of a particular individual, organization, or community.
Answer:
1: carbon footprint is the amount of carbon dioxide released into the atmosphere as a result of the activities of a particular individual, organization, or community.
2: A carbon footprint is a measure of the impact your activities have on the amount of carbon dioxide (CO2) produced through the burning of fossil fuels and is expressed as a weight of CO2 emissions produced in tonnes.
What could happen if a person doesn't get the proper amount of protein in his or her diet?
Answer: You can be hungrier more often. Your bones become weaker and easier to fracture. Your immune system weakens because your antibodies become less effective. It could lead to a build up of fluids and cause your feet to swell. Your hair becomes brittle and falls out. Your nails become brittle. Eating less proteins puts you a a higher risk of high blood pressure. Your muscles get weaker. And your skin gets flaky.

the answer is /a / or /c/Conservation biologists studying cheetah populations have determined that the lack of genetic diversity among the cheetahs is due to
genetic drift.
Which statement explains the most likely consequence of having a low genetic diversity on the cheetah population?
O A. The chances of a mutation occurring in the cheetah population are decreased, increasing the cheetah survival rate.
OB. The gene pool remains in equilibrium and future generations of cheetah offspring are stronger and better adapted to their
environments.
O C. The cheetah population becomes less likely to survive an outbreak of a disease or an environmental change, increasing the chance
of species extinction.
O D. Genetic variability is maintained from older cheetah populations that have survived and endured environmental stressors.
Answer:The correct answer is C
Explanation:
I did the test
The statement that described the most result of less genetic diversity should be option c. where the cheetah population should be less likely to survive.
What is genetic diversity?It means the range where the various inherited traits lies within a species should be considered. In terms of species, there should be high genetic diversity. Also, it contains various individuals that contains various traits. It should be important for the population for adapting the changing environment.
