Answers
The molecules classified as carbohydrates are oligosaccharides, monosaccharides, disaccharides.
What are the carbohydrates?
Carbs, or carbs, are sugar particles. Alongside proteins and fats, starches are one of three fundamental supplements tracked down in food varieties and beverages.
Your body separates starches into glucose. Glucose, or glucose, is the principal wellspring of energy for your body's phones, tissues, and organs. Glucose can be utilized right away or put away in the liver and muscles for sometime in the future.
There is nobody size-fits-all measure of starches that individuals ought to eat. This sum can differ, contingent upon variables like your age, sex, wellbeing, and whether you are attempting to lose or put on weight. Overall, individuals ought to get 45 to 65% of their calories from carbs consistently.

The cell cycle has a regular system of checks and balances that prevents damaged or mutated cells from proceeding to the next phase. One way an organism deals with the problems is to kill the damaged cell before it passes on the problem to its daughter cells. This is a normal process called apoptosis.
a. True
b. Fale
Answers
Answer:
A. True
Explanation:
Apoptosis is a normal cellular process in which the cell inherently programs the death of a mutated or damaged cell without affecting the healthy condition of the other surrounding cells by proliferating.
Apoptosis is a system of checks and balances that the cell uses to prevent damaged or mutated cells from proceeding to the next phase in the cell cycle. This curbs or prevent the damaged cell from passing on the problem to its daughter cells. Hence, according to this question, it is TRUE.
Fifty years ago, bed bugs were nearly eliminated in the United States by using of pesticides like DDT. Today bed bugs are back in beds and theaters. DDT is no longer used due to environmental issues. Pyrethrums are currently the top choice for bed bug infestations. Pyrethrums are especially useful to us because they generally have a stronger effect on bugs than on humans and animals.
Some bed bugs had mutations in their genetic code which allowed them to survive the chemical pesticide and they produced chemically resistant offspring. How can this be explained?
Question 5 options:

Dr. Robert Hazen has worked to develop a hypothesis that explains
the origin of life on Earth. His work has focused on hydrothermal vents, which are cracks in the ocean floor. Water heated by molten rock beneath the crust escapes from these vents at very high temperatures, producing hot, high-pressure environments at the vents on the ocean floor.
In order to provide evidence that these vents may be areas where life originated, which of the following states a null hypothesis Hazen might have used to begin his research?
(A) Organic molecules were transported to the hydrothermal vents via a meteorite, thereby seeding them with precursors for more complex molecules.
(B) The temperatures and pressures found in hydrothermal vents resemble conditions described in currently accepted origins of life hypotheses.
(C) Organic waste sinking to the ocean floor would have used the unique hot water environment as an energy source to begin manufacturing food.
(D) Chemosynthetic organisms can best develop in the hydrothermal environment, manufacturing nutrients for other living things to feed on.
Answers
Answer:
(B) The temperatures and pressures found in hydrothermal vents resemble conditions described in currently accepted origins of life hypotheses
Explanation:
We are told that Dr. Hazen wants to develop a hypothesis that explains
the origin of life on Earth.
Now, he focused on hydrothermal vents. That Water heated by molten rock beneath the crust escapes from these vents at very high temperatures, producing hot, high-pressure environments at the vents on the ocean floor.
This means the null hypothesis will be temperatures and pressures found in this initial condition he described while any other different from it will be the alternative hypothesis.
Looking at all the given options and comparing with the initial hypothesis conditions in the question, the correct answer is option B.
The origin of life can be seen as the natural process in which the origin of living things happen through non-living matter or smaller organic compound.
The null hypothesis is:
(B) The temperatures and pressures found in hydrothermal vents matches the conditions described in currently accepted origins of life hypotheses.
The null hypothesis for Dr. Robert Hazen hypothesisThe hypothesis says that hydrothermal vents are cracks in the ocean floor.It also states that there were high temperatures and high pressure environment.Thus, the option (B) The temperatures and pressures found in hydrothermal vents matches the conditions described in currently accepted origins of life hypotheses is the best null hypothesis for Dr. hazen to begin his research.

PLSS HELP how is gene knockout similar to gene sequencing?
Answers
Answer:
Gene knockout is a technique used to determine the function of a gene that has already been sequenced, which is achieved by analyzing the phenotype of the individual carrying the knockout mutation(s). Moreover, gene sequencing is a technique used to determine the sequence of a given gene, which allows to determine how gene variants (polymorphisms) may be associated with the phenotypes of the target trait.
Explanation:
In genetics, gene knockout is a technique used to trigger mutations in a (already) sequenced gene in order to inactive its function and observe the resulting phenotype for a particular trait. This approach that starts with the inactivation of a given gene and ends with the phenotype is known as reverse-genetics. On the other hand, gene sequencing can be defined as the methodologies/techniques/tools used to determine the nucleotide base pair sequence of a particular gene. The gene knockout technique involves knowing a priori the gene sequence in order to obtain a gene knockout (gene KO). The combination of the information obtained from these techniques can be used to determine how variation (genetic variation) affects the expression of a phenotypic trait.

Do you think an advanced civilizations may exist in the universe? Why or why not?
Answers
Answer:
Many other planets throughout the universe probably hosted intelligent life long before Earth did, a new study suggests.
The probability of a civilization developing on a potentially habitable alien planet would have to be less than one in 10 billion trillion — or one part in 10 to the 22nd power — for humanity to be the first technologically advanced species the cosmos has ever known, according to the study.
"To me, this implies that other intelligent, technology-producing species very likely have evolved before us," said lead author Adam Frank, a professor of physics and astronomy at the University of Rochester in New York. [13 Ways to Hunt Intelligent Alien Life]
In 1961, astronomer Frank Drake devised a formula to estimate the number of extraterrestrial civilizations that may exist today in the Milky Way.
Adam Frank and co-author Woodruff Sullivan of the University of Washington were interested in the odds that intelligent aliens have ever existed anywhere in the universe. So they tweaked the famous Drake equation, coming up with an "archaeological version" that doesn't take into account how long alien civilizations may last.
Frank and Sullivan also incorporated observations from NASA's Kepler space telescope and other instruments, which suggest that about 20 percent of all stars host planets in the life-friendly, "habitable zone," where liquid water could exist on a world's surface.

c. 40 amino acids
d. 12 amino acids
Answers
Answer:40
Explanation: a codon is three nucleotides. Provided that the sequence does not include a STOP codon, the polypeptide would have 40 amino acids
40 amino acids would be in the resulting polypeptide chain of a sequence of DNA that has 120 nucleotides.
CODONS:
A codon is a triplet nucleotide sequence in an mRNA molecule that encodes a particular amino acid. Each codon specifies an amino acid. A codon is made up of three nucleotides, whose combination determines the amino acid that is encoded. According to this question, a sequence of DNA has 120 nucleotides. This means that the number of codons that is accommodated in this sequence is 120/3 = 40 codons. Since 1 codon specifies 1 amino acid, therefore, 40 codons will specify 40 amino acids.Learn more about codons at: https://brainly.com/question/19153211?referrer=searchResults
