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.

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.

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.

Answer:

D. Maintaining homeostasis is something that needs to be learned

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

Answer:

a population that is adapted to its current environment.

Explanation:

The theory of natural selection explains the development of adaptive features by organisms required to survive in their current environment. The theory supports the survival of the fittest idea whereby those organisms with the most equipped environmentally adaptive features survive. Theae features are also passed from parents to offspring on a bid to facilitate their adaptation to their current environment. This means different organisms develop features required for each of their present environment.

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.
