explain what happens to food when it enters the mouth
Answer:
When food enters the digestive system through the mouth ... Food is then broken into smaller pieces just by a person chewing. The teeth then cut and also crush the food, While the food is mixed with saliva. The process of this basically helps to makes it soft and a lot more easier for a person to swallow food.

Why did the temperature change or not change during the reaction?
Answer:
When substances react and the temperature of the mixture decreases, the reaction is endothermic. ... If a reaction is exothermic, more energy is released when the bonds of the products are formed than it takes to break the bonds of the reactants. This is the reason for temperature change during a reaction.

Suppose virus A has a viral genome of 19,000 bp, and 10,000,000,000 viruses are replicated in an infected individual in a single day. Assume that a single mutation at a particular location in the virus A genome is needed for virus A to develop antiviral drug resistance to ledipasvir. The mutation can be a transition or transversion mutation. If RNA polymerase introduces an error in 1 of every 10,000 bases synthesized, how long will it take for virus A to overcome ledipasvir therapy and develop resistance? Round your answer up to a whole number of days.
Answer:
1 day.
Explanation:
From the given information:
The rate of mutation induced by RNA polymerase is:
[tex]\implies \dfrac{1}{10000}= 0.0001[/tex]
Since the genome comprise of 19000 bp;
To complete a single replication, the viral cycle induce: [tex]= \dfrac{19000}{1000}[/tex]
[tex]= 1.9 \ mutation \\ \\ \simeq 2 \ mutation[/tex]
However, in a single day; 10,000,000,000 viruses are reported to be replicated.
Hence, if a virus has 2 mutations; Then 10,000,000,000 virus will have:
[tex]= \dfrac{10,000,000,000}{2} \\ \\ = \text{5000000000 \ mutations \ in \ a \ half \ day which is half} \\ \\ \text{ the given no of the replicated virus}[/tex]
SO, to round this up to whole number, it will take 1 day (s) to overcome the therapy.
1. The biological manigestion of the traits
2. A condition where wherein two identical alleles are present
3. A condition wherein different alleles are present
Answer please
Answer:
1. phenotype
2. heterozygous
3. homo-zygous
Explanation:
In genetics, phenotype refers to the observable characteristics/ traits in a particular organism. An individual phenotype results from the interaction of genes and the environment. Moreover, in diploid (2n) species, an organism is heterozygous for a given trait when it carries two different gene variants or 'alleles' of the same gene. These two alleles are received from both parents, i.e., one allele from one parent and another one from the other parent. Finally, an organism is homo-zygous for a given trait when it carries two identical alleles of the same gene.

What weakens hurricanes when they reach the Atlantic Ocean
These storms diminish and disintegrate once they cross over land or across cold water, losing contact with the hot water that gives them strength.
What are hurricanes?A spiral arrangement of thunderstorms that produce torrential rain and squalls, a low-pressure center, and powerful winds are the characteristics of a tropical cyclone, a fast revolving storm system.
A tropical storm that has sustained winds of 74 mph or greater is referred regarded as a hurricane.
A storm's eye typically measures 20 to 30 miles in width and can reach distances of 400 miles.
Storms can be dangerous because of their torrential downpours, strong gusts, and storm surges.
Because they are no longer being fueled by the energy from the warm ocean waters, hurricanes typically lose strength when they make landfall.
Thus, these are the factors that weakens hurricanes when they reach the Atlantic Ocean.

How are plants of the savanna's highly specialized to grow in this environment of long periods of drought?
Answer:
In trees, most savanna adaptations are to drought--long tap roots to reach the deep water table, thick bark for resistance to annual fires (thus palms are prominent in many areas), deciduousness to avoid moisture loss during the dry season, and use of the trunk as a water-storage organ (as in baobab).
What uses bacteria to copy DNA?
O A. Nuclear transfer
O B. Gel electrophoresis
O C. Recombinant DNA technology
O D. Polymerase chain reaction
Answer:
C.
Explanation:
The method that uses bacteria to copy DNA is recombinant DNA Technology. To copy the DNA, the recombinant DNA method uses bacteria such as E. Coli whose plasmids are combined with various gene to produce the substance that is wanted.
Polymerase chain reaction uses bacteria to copy DNA.Therefore, the correct option is D.
What is polymerase chain reaction?Polymerase Chain Reaction is a laboratory technique used to amplify a specific DNA sequence, making many copies of it. The process involves repeated cycles of heating and cooling a reaction mixture containing the DNA template, primers, and a heat-stable DNA polymerase enzyme.
The DNA polymerase enzyme used in PCR is derived from a bacterium called Thermus aquaticus, which can withstand the high temperatures used in the reaction. By copying the DNA sequence multiple times, PCR enables researchers to study and analyze small amounts of DNA, such as those obtained from crime scenes or ancient fossils.Therefore, the correct option is D.

just did ap3x ;)
The costs of using coal is a direct cost that is Mining costs that is in option B as, the cost of related pollution is an indirect cost because it is not a direct expense associated with mining, but rather an expense that arises from the pollution that results from burning coal.
What is direct costs ?Direct costs are expenses that are directly tied to a specific activity or decision. In the case of coal, the direct costs would include the costs associated with mining, transporting, and processing coal. These costs are incurred as a result of the direct activity of extracting and utilizing coal.

Explanation:
Bacteria are sensitive to certain antibiotics like chloramphenicol and streptomycin, which kill the bacteria by interfering with translation through mechanisms that affect the ribosome's ability to function. If a researcher were to culture populations of Archaea and then treat them with either of the previously mentioned antibiotics, what would be the predicted results
Answer:
Explanation:
Neither antibiotic will have an effect on Archaeon populations because their ribosomes are different from bacterial ribosomes.
The predicted result of this experiment is that Archaea do not show any response towards specific antibiotics.
What are Antibiotics?Antibiotics may be defined as a type of medication that inhibits the growth of microorganisms and fight against bacterial infections in humans or animals.
Due to the alterations in the structural and functional unit of ribosomes, none of the antibiotics causes any significant effect on the body of Archaea.
