What is Puzzle 3 Summer break escape room kesler science answer?
Are scans done with MRI, CAT scan, PET scan, X-ray, or ultrasound machines?
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.

What leads to the changes in shape of the active site when pH changes?
A. more H+ interfere with the amino acid bonds
B. the OH- ions break apart the amino acids
Answer:
A. more H+ interfere with the amino acid bonds
Explanation:
Enzymes are also sensitive to pH. Changing the pH of its surroundings will also change the shape of the active site of an enzyme.
This contributes to the folding of the enzyme molecule, its shape, and the shape of the active site. Changing the pH will affect the charges on the amino acid molecules.
Answer: A. more H+ interfere with the amino acid bonds

Refer to the following information to answer the questions below. A man who is an achondroplastic dwarf with normal vision marries a color-blind woman of normal height. The man's father was 6 feet tall, and both the woman's parents were of average height. Achondroplastic dwarfism is autosomal dominant, and red-green color blindness is X-linked recessive. They have a daughter who is a dwarf with normal color vision. What is the probability that she is heterozygous for both genes
Answer:
Considering the whole progeny ⇒ the probability of having a girl heterozygous for both genes is 4/16 = 1/4 Considering only girls ⇒ the probability of having a girl heterozygous for both genes is 4/8 = 1/2Considering only dwarf girls with normal color vision ⇒ the probability of having a girl heterozygous for both genes is 4/4 = 1Explanation:

Scientists in Brazil have developed specific fertilizers and special breeds of soybeans and corn so crops can grow on large areas of tropical lands. This is valuable because farmers can help to feed the growing human population and strengthen the economy. However, trade-offs must be considered because farming on tropical lands can also A add helpful microorganisms to the soil B remove oxygen from the atmosphere C reduce populations of native species D reduce mutations and disease in wildlife populations
Answer:
C reduce populations of native species
Explanation:
The overexploitation of the land by farming practices represents one of the most important challenges that face wild populations and threatened species, representing a concern to biodiversity conservation. Farming practices can destroy the natural structure of the soil, reducing diversity by killing small animals (e.g., insects), bacteria, and fungi that live in the substrate. Moreover, runoff may also carry herbicides and pesticides used in monocultures that can damage aquatic ecosystems, disrupting and killing aquatic wildlife and polluting water sources. Some ecological farming methods that help to reduce biodiversity loss include, among others, the use of natural fertilizers, diversification of crops, biological pest control, etc.

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.

The student is studying the movement of substances across the cell membrane. She understands that some substances combine with special transport proteins to be carried across the cell membrane. The substances can move only from an area of higher concentration to one of lower concentration. This process is known as:
Answer:
Facilitated diffusion
Explanation:
Facilitated diffusion is the transport of hydrophilic molecules that can not freely cross the membrane. Channel protein and many carrier proteins are in charge of this transport. When uncharged molecules cross the membrane, they do it according to their concentration gradients, going from the more concentrated side to the lower concentrated one. When ions need to cross the membrane, the process depends on an electrochemical gradient.
Facilitated diffusion is a passive transport process because they only depend on electrochemical gradients, so they do not need any energy to occur.
