Answer:
0.8mm.
Explanation:
If the size of an object is about 1/4th the size of the field diameter so the size of an object is 0.8mm because the fourth part of field diameter is equals to 0.8mm. Due to knowing field diameter of microscope we can calculate the real size of objects that is too small which can't be seen with the naked eye. So one fourth part of field diameter is equal to 0.8mm.
Why is your body going through physical and chemical changes?
Answer:
(MY) body is only going through chemical changes because of my digestive juices, my saliva, and brain functions.

why does food get cold but drinks get hot
Answer:
it might be because of the room temperature.
Explanation:
since drinks are colder than the room temperature they will get warmer to be the same as the room temperature and because food is hotter than room temperature it gets colder to be the same as the room temperature. dont quote me on that just a guess
In the testes, sperm cells replicate and differentiate in the _________. Question 2 options: urethra septum tunica albuginea seminiferous tubules ductus deferens
Answer:
seminiferous tubules
Explanation:
Seminiferous tubules are coiled tubes where sperm cells are produced by a process referred to as spermatogenesis. These tubes are located in the testes or testicles (i.e., male reproductive glands/gonads). Each testicle contains approximately 250 compartments known as testicular lobules, while each testicular lobule has 1 to 4 seminiferous tubules which converge to form a single straight tubule. Once sperm cells mature, they travel through the seminiferous tubules to be stored in a coiled tube called the epididymis.

cientists think that the position of the nostrils gives modern whales an evolutionary advantage. Which of the following most likely describes how this adaptation is advantageous?
O The nostril position allows whales to obtain air more easily at the surface of the water.
The nostril position allows whales to obtain food more easily at the surface of the water.
O The space lett empty by the migrating nostrils has allowed modern whales to develop gills.
The space left empty by the migrating nostrils has allowed modern whales to develop teeth.
Answer: Its A my friend, how it helps!.
Explanation: I just completed the Test.
The nostril position allows whales to obtain air more easily at the surface of the water is most likely describes the advantage of adaptation.
What do you mean by adaptation?In biology, adaptation has three related meanings. It is the dynamic evolutionary process of natural selection that fits organisms to their environment, enhancing their evolutionary fitness. Secondly, it is a state reached by the population during that process.
The ability of living organisms to adjust themselves to their surroundings is called adaptation. Adaptations are the changes in structure or behaviour of an organism that will allow the organism to survive in that habitat.
Adaptations are unique characteristics that allow animals to survive in their environment. There are three types of adaptations: structural, physiological, and behavioral.

Zara had a birthday and was able to choose a pet. The pet that she chose was a beautiful clownfish named Bozo, a common salt water fish. Zara already has a tank with goldfish at home. Use your knowledge of diffusion & osmosis to tell Zara how to take care of Bozo.
Answer:
See the answer below
Explanation:
The advice I would give to Zara would be that she should keep Bozo in a separate tank with common salt water away from the goldfish. Bozo is a salt water fish while the goldfish can only survive in freshwater.
If Bozo is kept in a saltless water/freshwater tank with the goldfish, the water would be hypotonic to Bozo. Consequently, water will osmotically diffuse into the cells of Bozo, the cells would become turgid and lyse, and this would lead to the death of the fish.
If the goldfish is kept in the same salt water tank with Bozo, the salt water would be hypertonic to the goldfish. Consequently, water will osmotically diffuse out of the cells of the goldfish into the surrounding salt water, the cells of the goldfish would become flaccid, and this would lead to the death of the fish.

What should Brenda do when a patient wants to make payments on an outstanding patient account balance?
Answer:
Brenda should facilitate the patient's resolve to make the payments by ensuring that an effective schedule is worked out with the patient and that the patient is able to stick to the agreed schedule.
Explanation:
Brenda should always make sure that patients are encouraged to make good on their promises to pay for their medical treatment. She should be compassionate with the patient by showing understanding and sharing information on payment terms. She should be very creative in scheduling payments in such a way as to ensure that the patient makes payments as scheduled. She can even work out some fees for late payments to encourage the patient to stick to the schedule.

Butanol was used in the production of:
O Cordite
O Nitroglycerin
O Fizzy beverages
Synthetic rubber
Answer:
Synthetic rubber.
Explanation:
Polymerization can be defined as a type of chemical reaction in which molecules that are relatively small in size chemically combine to form a huge chain of molecules.
Simply stated, polymerization refers to a chemical reaction where two or more smaller molecules react to produce larger molecules of the same network or repetitive structural units.
In polymerization, the relatively small molecules are generally referred to as monomers while the larger molecules they produce are known as polymers.
Butanol was used in the production of synthetic (artificial) rubber through a fermentation process.
What is the medical term for the process or procedure that destroys or inhibits disease-causing microorganisms to prevent infection:
Answer: Sterilization.
Explanation:
Sterilization is the process that kills, or deactivates all forms of life so then a product is considered free of viable microorganisms. This process must be designed, validated and carried out to ensure that it is capable of eliminating the microbial load of the product.
Since sterility cannot be demonstrated without causing the complete destruction of the products, sterility is considered when the probability of a product being contaminated is acceptably remote. A critical product is considered sterile when the probability of a microorganism being present in an active or latent form is equal to or less than 1 in 1,000,000 (sterility safety factor 10^-6).
Agents that kill microorganisms are called microbicides or more commonly called "germicides". If the agent kills bacteria, it is called a bactericide. And if it kills fungi, then it is called a fungicide. It is important to consider than after an exposure of the sterilized object to the air or its surroundings, it will have become contaminated again with microorganisms.
Examples of sterilization include physical methods and chemical methods. Physical methods include:
Wet heat (in steam autoclave) Dry heat (in sterilization oven) Radiation (gamma radiatio, electron beam, X-ray, ultraviolet, microwave, white light)Chemical methods include a variety of chemicals in liquid and vapor form, for example:
Hydrogen peroxideChlorine dioxideOzone gasesEthylene oxidePropylene oxidePeracetic acidQuestion 20 of 26

A) 2.
B) 4
C) 23

Answer:
A) 2.
I hope it helps :)
Explanation:
During mitosis, a eukaryotic cell undergoes a carefully coordinated nuclear division that results in the formation of two genetically identical daughter cells. Mitosis itself consists of five active steps, or phases: prophase, prometaphase, metaphase, anaphase, and telophase.
5. What would be the effect if a gene has a mutation in the location of the stop codon? (4 points)
During translation protein synthesis won't stop when it should so amino acids will continue to be placed and the peptide will be bigger.
Answer:
In genetics, a point-nonsense mutation is a point mutation in a sequence of DNA that results in a premature stop codon, or a point-nonsense codon in the transcribed mRNA, and in a truncated, incomplete, and usually nonfunctional protein product.
