Answer:
Phenotype
Explanation:
"only four phenotypes result from the six possible ABO genotypes. How does this happen? To understand why this occurs, first note that the A and B alleles code for proteins that exist on the surface of red blood cells; in contrast, the third allele, O, codes for no protein."

A biochemist was given a sample of an unknown organic compound and asked to determine the class of organic compounds to which it belonged. The chart shown represents the results of the biochemist's analysis of the sample.
Based on these results, to which class of organic compounds did this sample belong?
protein
salt
lipid
carbohydrate
Answer:
d or b is my guess
Explanation:
........................
Based on the result given in the table, a class to which organic compounds of this sample belong to carbohydrates. Thus, the correct option for this question is D.
What are Organic compounds?Organic compounds may be defined as a huge group of chemical compounds in which one or more atoms of carbon are covalently associated with atoms of other elements such as hydrogen, oxygen, or nitrogen to a large extent.
Some examples of organic compounds are carbohydrates, nucleic acids, proteins, lipids, etc. Based on the table, the number of atoms of carbon, hydrogen, and oxygen is found to be highest while sulfur, nitrogen, and phosphorus are completely absent.
According to this, carbon, hydrogen, and oxygen are the constituents of organic compounds known as carbohydrates.
Therefore, a class to which organic compounds of this sample belong to carbohydrates. Thus, the correct option for this question is D.

What would happen to the nitrogen cycle if bacteria was no longer present
Answer: Without bacteria around to break down biological waste, it would build up. And dead organisms wouldn't return their nutrients back to the system.
Explanation:
The simplest way to explain it is:
Without bacteria, the nitrogen cycle would stop.
Bacteria is responsible for converting ammonia into nitrogen in soil. The nitrogen feeds plants which all go hand-in-hand with all of the Earth's cycles.
What is evolution? How can evolution be scientific when no one was there to see it happen?
Answer:
Evolution is looking back and using scientific inference to make a timeline on adaptation of a species over time.
Explanation:
Looking at skulls, skeletal remains and carbon footprints left behind, we can compare and date remains of early humans and other species from years ago and compare them to late and modern remains. Thus making a timeline and showing the slow evolution of our adapting species.

5. Which process usually results in offspring that exhibit new genetic
variations?
Answer:
It's the first choice that is fertilization
The process that usually results in offspring that exhibit new genetic variations is known as fertilization. Thus, the correct option is 1.
What is Genetic variation?Genetic variation may be defined as the occurrence of differences in sequences of genes between individual organisms of a species. The most prominent causes of genetic variation are mutations, sexual reproduction, gene flow, genetic drift, etc.
The first option describes the process of successful fertilization between male and female gametes. Thus, this sexual reproduction is the most characteristic process of inducing genetic variations among individuals of the same species.
The option third illustrates the process of budding in hydra, and the option reveals the process of binary fission in amoeba. Both are types of asexual reproduction in which the offspring is produced by a single parent only. And hence, they produce identical types of offspring without much genetic variations.
Therefore, the process that usually results in offspring that exhibit new genetic variations is known as fertilization. Thus, the correct option is 1.

Sulfur dioxide is considered a serious air pollutant. SO2 emissions that lead to high concentrations of SO2 in the air generally also
lead to the formation of other sulfur oxides (SOx). SO, can react with other compounds in the atmosphere to form small particles, and
these particles contribute to particulate matter (PM) pollution. Small particles may penetrate deeply into the lungs and in sufficient
quantity can contribute to health problems. Which of these is NOT a source of SO2 pollution?
A)
manufacture of cement
