describe the hygiene and care of the tooth
Answer:
in my opion, hygien and care for your teath is more like, brusshing your teeth three times a day if possible and also mouth wash and dont forget to floss if possible
Explanation: My explination for this is teeth are important and needed to be taken care of.
Answer:
Hygiene is a series of practices performed to preserve health.
According to the World Health Organization, "Hygiene refers to conditions and practices that help to maintain health and prevent the spread of diseases." Personal hygiene refers to maintaining the body's cleanliness.
Many people equate hygiene with 'cleanliness,' but hygiene is a broad term. It includes such personal habit choices as how frequently to take a shower or bath, wash hands, trim fingernails, wash clothes, and basically self care. It also includes attention to keeping surfaces in the home and workplace, including bathroom facilities, clean and pathogen-free. Many people know without taking care of your teeth the food would leave many bacteria and without flossing it, it can lead to the food between your teeth to get bad causing a cavity, then tooth decay.
Good luck.

Explanation:
Tell me if I am wrong. I hope this helps :)
Cell division in a cell takes place in the single-celled organisms to reproduce and pass along the genetic information of the cell. Thus, the correct option is B.
What is Cell division?Cell division is the process of division of cell through which a parent cell divides into two daughter cells with equal genetic content which are similar to the parent cell. Cell division generally occurs as a part of a larger cell cycle in which the cell grows in size and the cell replicates the chromosomal material before it is undergoing cell division.
In the unicellular organisms, cellular division is a significant process through which a unicellular organism undergoes development and result into the formation of a new organism with genetic material which is similar to the parent cell. In the multicellular organisms, process of cellular division helps in maintaining a balance between the genetic material such as the DNA and the RNA contents as well as the nuclear and cytoplasmic contents of the cell.
Therefore, the correct option is B.

11. How has our misguided, or inappropriate, use of antibiotics led to the development of organisms like
MRSA and VRSA?
Answer:
1. use of the wrong antibiotic
2. use of insufficient concentration of the right antibiotic
Explanation:
MRSA means Methicillin-resistant staphylococcus aureus
VRSA means Vancomycin-resistant Staphylococcus aureus
These are resistant forms of the bacteria Staphylococcus aureus to the antibiotics mentioned.
Bacterial resistance to antibiotics occurs when bacteria develop mechanisms that protect them against the effects of previously effective antibiotics.
Misguided and inappropriate use of antibiotics results in resistance, and they mainly occur as a result of two activities:
1. Use of wrong antibiotics: antibiotics are chosen using a microbiological technique called 'sensitivity testing', to determine which antibiotic is effective against a bacterium. However, when antibiotics are taken without proper sensitivity testing, the bacteria develop resistance against such antibiotics.
2. Use of inadequate concentration of the right antibiotic: This involves using less than the minimum inhibitory of minimum bactericidal concentration of an antibiotic against a bacteria. In this case, the organism has ample time to evolve in the presence of the antibiotic, hence the occurrence of resistance.
Consider what you know about biotic and abiotic factors in an ecosystem. What is one of the reasons that nutrients in a vegetable patch might be considered abiotic?

If a female fruit fly heterozygous for red eyes (X RX r) crossed with a white-eyed male (X rY), what percent of their offspring would have white eyes? (Draw a Punnett Square.)
Answer:
6.25%
Explanation:
Given that:
The trait of a female fruit fly that is heterozygous for red eyes = XRXr; &
The trait of a white-eyed male is XrY_ ;
since Y is dominant y; the male trait can either be XrYR or XrYr
So, let assume that it is XrYr
Then; if each trait self crossed; we have:
XRXr = XX Xr XR Rr
XrYr = XY Xr rY rr
Thus, the punnet Square can be computed as:
XX Xr XR Rr
XY XXXY XXYr XXYR XRYr
Xr XXXr XXrr XXRr XRrr
rY XrYX XxYr XrYR RrYr
rr XrXr Xrrr XrRr Rrrr
∴
the percentage of offspring that would have white eyes XrY_ is:
1/16 = 0.0625
= 6.25%

How did Hershey and Chase use radioactivity to draw a conclusion about proteins and DNA?
Hershey and Chase studied bacteriophages which are viruses that attack bacteria. They labeled the bacteriophage with radioactive isotopes to see where it goes when a virus attacks.
What is Hershey and Chase experiment?They discovered that nearly all the radioactivity was found in phosphorus, confirming that DNA contains genetic material, not protein.
The final experiment, also known as the Waring Blender experiment, in which Hershey and Chase demonstrated that phages only injected their DNA into host bacteria and that the DNA acted as the replicating genetic element of phages, is the Hershey-Chase experiment that is most well-known.
Hershey and Chase discovered proof that phages introduced their DNA into host bacteria in the prior experiment.

1. The St. Lucie River drains Lake Okeechobee into the Atlantic Ocean.
What is the relationship among the parts of this system?
Answer:
The St Lucie canal serves as an outlet of drainage for the Okeechobee Lake through the St Lucie River and out to the Atlantic Ocean.
Explanation:
The St. Lucie River is an estuary in Florida, in the United States. It was basically a freshwater system before an inlet was dug to provide access directly to the Atlantic Ocean.
Lake Okeechobee is the second largest freshwater lake in the United States. Water flows into the lake from various sources with Kissimmee River being the major source.
Because of the high levels of water in Lake Okeechobee, the St. Lucie canal was constructed in the 1920s. The St. Lucie canal provides a good outlet from the Okeechobee lake, through the St. Lucie River and out to the Atlantic Ocean.

Which goes where ? Mitosis Vs. Meiosis
Answer:
Mitosis, Meiosis, and both are written below
Explanation:
Mitosis: produces more somatic (body) cells, purpose is for healing and growing, the daughter cells are exact replicas
This is because mitosis occurs in body cells and is used for growth, so all the daughter cells are the same.Meiosis: results in sex cells (gametes), results in eggs and sperm, purpose is for creating new individuals (eventually), each daughter cell is different, has 2 separate division stages
This is because meiosis occurs in gametes and is used in reproduction.Both: Chromosomes need to replicate before the whole process begins, a form of reproduction
This is because both are reproducing (they are dividing) and DNA must be replicated so each daughter cell has it.Can a single cell be a living organism?

A student performed an experiment by placing the de shelled egg in a concentrated salt solution for 5 minutes.What changes did he observe in the egg?Name the process
Answer:
the egg begins to shrink
Explanation:
During the 5 minutes that the egg is in the concentrated salt solution he would notice that the egg begins to shrink. This occurs due to the process known as osmosis which happens when a solvent passes a semipermeable membrane towards where there is a higher concentration which in this case would be within the egg. Since the egg would contain more water than the salt solution causing it to shrivel and shrink.
Which stage of the cell cycle lasts longest?
Answer: i think the Interphase because
Interphase is the longest part of the cell cycle. This is when the cell grows and copies its DNA before moving into mitosis. During mitosis, chromosomes will align, separate, and move into new daughter cells. The prefix inter- means between, so interphase takes place between one mitotic (M) phase and the next.
