Answer:
vaccines were designed by using new technologies (i.e., RNA-based vaccines and adenovirus-based vaccines)
Explanation:
RNA-based vaccines are vaccines based on the delivery of specific messenger RNA (mRNA) sequences that are capable of encoding only one viral protein, thereby preventing the complete viral cycle/replication. Subsequently, this protein is recognized by the immune system that generates memory immunity by synthesizing specific antibodies against this protein (in this case, the spike S protein). On the other hand, adenovirus-based vaccines are vaccines designed by inserting a transgene cassette into an adenovirus which is used as vector to produce one specific viral protein inside the host. Like mRNA vaccines, this antigenic viral protein is then recognized by the immune system in order to produce antibodies against a defined protein epitope, thereby producing memory immunity.

Darwin proposed as the process that causes evolution to occur.
Answer:
natural selection
Explanation:
Darwin proposed natural selection as the process that causes evolution.
According to the theory of natural selection, the environment naturally selects for genes that confer fitness to organisms over every other gene. In other words, organisms that are able to adapt to an environment survive and contribute more to the subsequent generation while those that are poorly adapted contribute less and gradually fade away from the population.
For example, when a drug is taken a particular pathogen, the susceptible ones among the pathogen's population will die off while the ones with the resistance gene survive, reproduce, and pass on the resistance gene to the subsequent generation. Consequently, the same drug might not work at all for the new generations of the pathogen because the gene that confers fitness has been selected for.

Which factor makes enzymes well-suited to the role of catalyst in a biochemical reaction?
A)Enzymes do not affect the energy of a reaction.
B)Enzymes slow down reactions so products can form.
C)Enzymes can be reused because they do not permanently bond with substrate.
D)Enzymes can only bind to other enzymes so the same product is formed each time.
Answer: C
Explanation: Once an enzyme binds to a substrate and catalyzes the reaction, the enzyme is released, unchanged, and can be used for another reaction.
Enzymes can be reused because they do not permanently bond with substrate.
What are Enzymes?
A biological catalyst called an enzyme is usually always a protein. It accelerates a certain chemical reaction in the cell. The enzyme is continuously employed during the reaction and is not destroyed. Each enzyme molecule found in a cell is unique and tailored to a particular chemical reaction.
Proteins called enzymes assist our bodies' chemical reactions move forward more quickly. For several processes, including digestion and liver function, enzymes are crucial.
Health issues might result from having too much or too little of a specific enzyme. Healthcare professionals can also use the enzymes in our blood to look for injuries and illnesses.
Therefore, Enzymes can be reused because they do not permanently bond with substrate.

How do cells support the evolution theory?
Answer:
Hope this helps!
Explanation:
The endosymbiotic theory explains how eukaryotic cells evolved. The large and small cells formed a symbiotic relationship in which both cells benefited. Some of the small cells were able to break down the large cell’s wastes for energy. They supplied energy not only to themselves but also to the large cell.

Growers around the world produce about 3.2 x 107 metric tons of sunflowers each year. One
metric ton is the same as 1.1 short tons. How many short tons of sunflowers do worldwide
growers produce annually?
Answer:
3.5264 x [tex]10^{7}[/tex]
Explanation:
The metric ton is used as a unit of mass. The metric ton in British units can be represented as 2240 pounds or long ton whereas in United state is termed as 1.102 short ton.
In the given question, it has been mentioned that the growers around the world produce about 3.2 x [tex]10^{7}[/tex] a metric ton of sunflower.
So the short ton produced will be
= ( 3.2 x [tex]10^{7}[/tex] ) x 1.102
= 3.5264 x [tex]10^{7}[/tex] short ton.
Thus, 3.5264 x [tex]10^{7}[/tex] is the correct answer.

Which statement accurately describes radioactive dating?
A.Geologists use only one type of radioactive dating.
B.Geologists compare parent and daughter elements to determine rock type.
C.Geologists will measure how stable multiple parent elements can decay into multiple daughter elements.
D.Geologist compare the observed abundance of naturally occurring radioactive isotopes and their decay products using decay rates.
Answer:
D. Geologist compare the observed abundance of naturally occurring radioactive isotopes and their decay products using decay rates.
Explanation:
Radioactive dating is the method in which radioactive isotopes are employed to evaluate the age of rocks and ores. There are many complex radioisotopes utilized for radioactive dating is like Potassium, Uranium, and Carbon. Radioactive dating operates on the system that a radioactive isotope can fade into the constant daughter nuclei at a steady rate. Geologist commonly uses the system for half life. Half-life is the time needed for half of the radioactive element to decline. This is fixed for a selective element.

Match each underlined word to its correct meaning based on the context of the sentence. Tom had long been picking his way cautiously through this treacherous forest; stepping from tuft to tuft of rushes and roots, which afforded precarious footholds among deep sloughs. It was a dreary memento of the fierce struggle that had taken place in this last foothold of the Indian warriors. He was sulky, however, and would not come to terms: she was to go again with a propitiatory offering, but what it was she forbore to say. At this propitious time of public distress did Tom Walker set up as a usurer in Boston.

Marie Curie was born Marie Sklodowska in Warsaw, Poland, in 1867. The girl of a physics teacher, she was a talented student and in 1891 visited study at the university in Paris. With highest honors, she received a degree in physical sciences in 1893 and in arithmetic in 1894. That year she met state capital Curie, a noted French man of science and chemist who had done vital add magnetism. Marie and Pierre married in 1895, marking the start of a scientific partnership that will accomplish world renown.

Different forms of a gene account for variations in the inherited traits
An organism inherits two genes for each trait, one from each parent.
Some alleles are dominant over others for a given trait.
The two genes of a given trait segregate during gamete production.

Answer: Mendel's research lead to several conclusions about the traits and its passing through generations. The two of the conclusion are different forms of a gene account for variation in the inherited traits and some alleles are dominant over others for a given trait.
Explanation
George Mendel was a famous biologist. His research was on genes and traits. His experiment shows how genes gets transferred from parents to offspring. Also he stated about the behavior and dominance and recessive nature of that alleles.
He also gives the possibility of dominance of a trait over other trait. The different forms of gene are responsible for various types of inherited traits in an organism.

Explanation:
the classroom is a community because its people of different cultures and race that come together and be one
all the mice in the classroom are considered a population because population is the number of people in a certain area
in the third statement there are all forms of organisms hence showing the biodiversity that ecosystems tend to have
the aquarium provides shelter to earthworms proving them with food of which a habitat provides both shelter and food
