Answer:
MRI: Magnetic resonance imaging (MRI) uses the body's natural magnetic properties to produce detailed images from any part of the body.
CAT/CT scan: is an upgraded version of an X-ray, which it uses multiple x-rays taken from different angles all around a body. Then uses a computer to create complex cross-sectional images of parts of a body
PET scan: uses radioactive tracers dyes which put into a body(by being swallowed, injecting, etc.). Which is tracked by the PET scanner, creating an image. PET helps to visualize the biochemical changes taking place in the body, such as the metabolism (the process by which cells change food into energy after food is digested and absorbed into the blood) of the heart muscle.
X-ray: when a negatively charged electrode is heated by electricity and electrons are released. Which produces energy that is directed toward an anode at high velocity. Producing an X-ray when the energy collides with the atoms in the metal plate.
Ultrasound: using a small transducer it both transmits sound waves into the body and records the waves that echo back.
Explanation:
Answer:
I cannot figure out what it is you would like to know. Please think about how your question is worded, and make it clear. In usual medical terminology, static x-rays produce images but are not considered scans, whereas all the others are ‘scans’. CT uses X-rays to make a ‘scanned’ image of internal soft tissues that do not show well on simple static X-ray imaging. MRI uses magnetism and radio ‘waves’, ultrasound uses a version of echolocation, PET uses a radioactive ‘tracer’ compound.
why might scientists be wary of the results of a single experiment testing a particular treatment, even when the results are peer reviewed and statistically significant
Answer:
The results may not be true for humans if the experiment used a model organism.
Explanation:
An animal model is an animal species used in research that mimics diverse human traits/features such as, for example, human response to certain diseases. Thus, animal models may provide useful information related to human developmental biology and human diseases (i.e., prevention, diagnosis, treatment, etc). However, in general, experiments involving animal models cannot be used to predict human outcomes. For example, in genetics, animal models exhibit different features to humans, including but not limited to genomes (i.e., different number and structure of chromosomes), genes, gene regulatory pathways, epigenetics gene regulatory mechanisms, etc. In consequence, animal tests may be unreliable and therefore their results cannot be directly extrapolated to human subjects.

Woolly mammoths became extinct thousands of years ago, while other species of mammals that existed at that time still exist today. The woolly mammoths became extinct, unlike the other species, because the woolly mammoths *
1 point
produced offspring that all had identical inheritable characteristics
faced a struggle for survival
learned to migrate to new environments
had certain inheritable traits that enabled them to survive
Answer:
faced a struggle for survival
Explanation:
The woolly mammoths became extinct, unlike the other species, because the woolly mammoths faced a struggle for survival due to changing of environmental conditions. Global warming is the main cause of extinction of woolly mammoth which destroy their habitats about 10,500 years ago. The environmental conditions are not favourable for them so they faced struggle for survival which causes extinction of woolly mammoth.

Following glycolysis and the citric acid cycle, but before the electron transport chain and oxidative phosphorylation, the carbon skeleton of glucose has been broken down to CO2 with some net gain of ATP. Most of the energy from the original glucose molecule at that point in the process, however, is in the form of ____
Answer:
The correct answer is - NADH.
Explanation:
Glycolysis is a multistep part of cellular respiration in which food is broken down to give off energy in a form of ATP. In glycolysis, the end product is converted to Acetyl-CoA using the pyruvate dehydrogenase enzyme.
During the citric acid cycle and oxidative phosphorylation, there is NAD reduces and turns to NADH that moves to the mitochondria. It is converted to energy using redox reactions. Most of the energy from original glucose molecules are transported and exists in the forms of NAD to NADH.
When we breathe in and out normally during rest, this is called “quiet” inspiration (and expiration). It is also called tidal volume, as it refers to the “tides”. How much air (the volume) do we typically breathe in or out during quiet breathing (in ml...you will have to convert from Liters to Milliliters)?
Answer: the amount of air that normally enters the lungs during quiet breathing, which is about 500 milliliters.

Why does the skeleton stop growing in length?
a
Because the cartilage in the growth plate has been
replaced by bone.
b
Because there is not enough calcium and other
nutrients in the body.
Because the growth plates stop working
d Because the bones reach their maximum length
Answer:
Bones increase in length because of growth plates in the bones called epiphyses. As puberty progresses, the growth plates mature, and at the end of puberty they fuse and stop growing. ... After the growth plates fuse, there is no more increase in height, and we all then shrink gradually as we get older.
What is true about Anemia? *
1. Disorder of platelets
2. uncontrolled production of WBCs
3. Increase in number of RBCs
4. Abnormal production of chain of Hemoglobin
Answer: 4. Abnormal production of chain of Hemoglobin
Explanation:
Anemia is a condition where the cells in the body do not get enough oxygen because the red blood cells needed to transport them are either too little or are dysfunctional.
One way the red blood cells can be dysfunctional is when they have an abnormal type of hemoglobin. Hemoglobin is necessary in red blood cells to enable to transportation of oxygen and if it is dysfunctional, oxygen will have problems being transported which would lead to anemia.

A cat with LONG HAIR (heterozygous) is a carrier of the short hair allele. Its mate has SHORT HAIR. Use a Punnett Square to determine the probability of their offspring having LONG HAIR.
Group of answer choices
25%
100%
0%
50%
75%
Answer:
50%
Explanation:
Hi there!
We are given the hair types of two cats
The first one has long hair, and it's heterozygous, meaning it has one dominant, and one recessive allele. We are given that it is a carrier of the short hair allele, meaning in its genotype, it has the short hair gene (that doesn't necessarily mean it's there in its phenotype). However, since it has long hair (genotype), that means that the long hair allele is dominant (the gene that will always show), and the short haired one is recessive (the gene that gets "covered up" by the dominant allele). Let's say the genotype of the long haired cat is Tt, where T is the long hair, and t is the short hair
The second cat has short hair, and as we have mentioned above, the allele for short hair is recessive, so the short haired cat has 2 copies of the short hair allele. Its genotype is tt

Consider two solutions of different sodium concentrations separated by a selectively permeable membrane. The net movement of water across the membrane will be from the area of ______ sodium concentration to the area of ______ sodium concentration.
Answer:
Consider two solutions of different sodium concentrations separated by a selectively permeable membrane. The net movement of water across the membrane will be from the area of high sodium concentration to the area of low sodium concentration
Explanation:
In this process, only water molecules can pass through the selectively permeable membrane. As the solution has different concentrations of solute, the water molecules will move from the more concentrated solution to the less concentrated solution. The process is called osmosis and is completed when both solutions have the same concentration.
What is the greatest threat humans pose to biodiversity?
Answer:
habitat loss, over-harvesting, and introduction of exotic species
Explanation:
The way that people have altered natural environments to create room for farms or to collect natural resources has posed the greatest harm to biodiversity yet, but as climate change intensifies, it will have a rising influence on ecosystems.
What is biodiversity loss?The term "biodiversity loss" describes the decline in biodiversity brought on by the extinction or relocating of species. Some people might not consider the extinction of a certain species to be significant, especially if it is not a charismatic species such as the Bengal tiger or the humpback dolphin.
However, according to estimates from scientists, the present pace of species extinctions is several times higher than the background, or average, rate seen throughout Earth's history. Within our lifetimes, this amounts to the extinction of tens of thousands of species.
The breakdown of ecosystems is anticipated to have drastic repercussions on human welfare. Because of the intricate relationships between species, a loss of biodiversity may have a ripple effect on ecosystems.
One species' extinction, for instance, may result in the extermination of another. Scientists evaluate which species are in danger of extinction as well as the state of the ecosystems to gauge the loss of biodiversity.
Therefore, the way that people have altered natural environments to create room for farms or to collect natural resources has posed the greatest harm to biodiversity yet, but as climate change intensifies, it will have a rising influence on ecosystems.
