Doctors normally need to do a biopsy to diagnose cancer :)
A biopsy is a procedure in which a doctor will give a sample of client's tissue to a Pathologist who examines it with a microscope and runs tests based on the sample.
Answer:
If you have a symptom or a screening test result that suggests cancer, your doctor must find out whether it is due to cancer or some other cause. The doctor may start by asking about your personal and family medical history and do a physical exam.

How does the carbon in grass become part of a lion?
A trout moves from a warm environment into a cold environment. Predict how the saturation status of hydrocarbon chains might change to ensure proper membrane fluidity in the new cold environment.
Answer:
The correct answer is - The hydrocarbons would become less saturated to increase the fluidity of the membrane
Explanation:
The ratio of saturated and unsaturated fatty acids or hydrocarbon chains is responsible for the membrane fluidity at cold temperatures. Cholesterol is an important part of membrane fluidity as it functions as a buffer, it inserts in phospholipids to preventing lower temperatures from inhibiting fluidity and at higher temperatures stabilizes the cell membrane and increase melting point and prevent increasing fluidity.
Moving from high temperature to low temperature hydrocarbon chains become less saturated in order to increase fluidity as it inserts cholesterols into phospholipids and decrease saturation.

The tap water is having a pH of 10
True or false
Answer: True
Explanation: Tap water is made slightly alkaline because acidic water could corrode metal pipes. It depends on country how high pH is. In some countries, where metal pipes are widely used pH could be even 10

11. Describe how the climate most likely changed between 220 million and 12 thousand years ago
Answer:
The Earth was formed about 4.5 billion years ago—that's a very long time ago! It's hard to say exactly what the Earth's daily weather was like in any particular place on any particular day thousands or millions of years ago. But we know a lot about what the Earth's climate was like way back then because of clues that remain in rocks, ice, trees, corals, and fossils.
These clues tell us that the Earth's climate has changed many times before. There have been times when most of the planet was covered in ice, and there have also been much warmer periods. Over at least the last 650,000 years, temperatures and carbon dioxide levels in the atmosphere have increased and decreased in a cyclical pattern.
These two clue show how the amount of carbon dioxide and the Earth's temperature have changed over the last 650,000 years. Both clue show a similar up-and-down pattern.
People didn't cause the climate change that occurred thousands or millions of years ago, so it must have happened for other natural reasons.
Will pigs ever fly?
Support your answer with suitable examples.
Answer:
NO
Explanation:
the pigs will never be able to fly as the birds have:
wings – these enable the force of lift.
lightweight, smooth feathers – this reduces the forces of weight and drag
streamlined body – this helps reduce the force of drag (a shape that lowers the friction drag)
light bones – a bird’s bones are basically hollow with air sacs and thin, tiny cross pieces to make bones stronger – this reduces the force of weight
Meanwhile the pig is obviously heavier, having a stronger force of gravity, and does not have the same type of "lightweight" bones that the birds have.
Answer:yes they might
Explanation:
Birds are able to breed with pigs and pigs might get wings
️What are any 3 differences between ecosystem biodiversity and genetic biodiversity?help.....
Answer:
Genetic diversity are the differences in DNA among individuals within a species or population. Species diversity is the number or variety of species in the world or in a particular region. Ecosystem diversity is the number or variety of ecosystems within a particular area.
Which type of bond is the strongest?
A. lonic
O B. Covalent
C. Metallic
D. Hydrogen
Answer:
A
Explanation:
The two strongest bonds are ionic and covalent, but generally, ionic is viewed as the stronger bond because of the ion-ion force that occurs within the bond. It does depend on other factors though.
what do the results suggest about ways that milkweed bug populations are limited in nature?
Answer:
Temperature.
Explanation:
Temperature was the only limiting factor that controls and limits the size of the population of milkweed bug in the nature because these milkweed bug are very sensitive to temperature. Little increase or decrease in temperature can cause adverse effect to the population f milkweed bug in that environment. Milkweed bugs need food, water, space, shelter and a mate in order to survive a well as increase in population of milkweed bug.

Can someone help me if this is correct
Answer:
I think your answer is wrong. The right answer is D. Nucleus & Ribosome.
Explanation:
A process that takes place in the cells of all living things: the production of proteins. This process is called protein synthesis, and it actually consists of two processes — transcription and translation. During translation, the genetic code in mRNA is read and used to make a protein. These two processes are summed up by the central dogma of molecular biology: DNA → RNA → Protein. In eukaryotic cells, transcription takes place in the nucleus. During transcription, DNA is used as a template to make a molecule of messenger RNA (mRNA). The molecule of mRNA then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs.
The nucleus contains the cell's DNA and directs the synthesis of ribosomes and proteins. Typically, the nucleus is the most prominent organelle in a cell. Eukaryotic cells have a true nucleus, which means the cell’s DNA is surrounded by a membrane. Therefore, the nucleus houses the cell’s DNA and directs the synthesis of proteins and ribosomes, the cellular organelles responsible for protein synthesis.
