The body can be invaded by (mutagens / bryophytes / tracheophytes / pathogens), which are harmful microorganisms that cause (infectious / chronic / malignant / proactive) diseases. The body then initiates a(n) (homeostasis / feedback / inflammatory / inhibition) response, which may involve redness, swelling, and fever.
Answer:
1. Pathogens
2. Infectious
3. Inflammatory
Explanation:
A pathogens is any disease-causing microorganism or agent. Pathogens such as bacteria, virus etc. invade the body of a living organisms and cause an abnormal state of health (disease) in such organism. The diseases caused by pathogens are usually infectious, meaning that it can spread from one individual to another.
This attack by pathogens triggers an inflammatory response by the body of the host. This inflammatory response is visibly characterized by redness, swelling, and fever etc.
An examination of racial classifications from around the world indicates that Group of answer choices the best racial classifications are based solely on phenotypic traits. all cultures classify races similarly. the best racial classifications are based solely on genotype. the classification of racial types is an arbitrary, culturally specific process. the best racial classifications are based on both genotype and phenotype.
Answer:
the classification of racial types is an arbitrary, culturally specific process.
Explanation:
Racism can be defined as an act, practice or policy by an individual, group of people or institutions which typically involves promoting the ideas and belief that a race is superior in comparison with another. Thus, it simply means the believe that a particular race has dominance over another (an inferior race).
An examination of the classifications of races from around the world indicates that the classification of racial types such as Africans, Americans, Indians, Asians, Black-Americans, Hispanics, etc., is typically based on individual perception, not objective and an impulsive (arbitrary), culturally inclined or specific process.
This ultimately implies that, the classification of racial types is considered not to be based on any form of objective distinction but may be defined by a person's culture.
A culture can be defined as the general way of life of a group of people living together in a particular location or society.
Basically, culture comprises of beliefs, values, behaviors, language, dressing, cuisine, music, symbols, arts, social habits, knowledge, customs, laws pertaining to a particular group of people living together in a society.

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.
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.

Answer:
b
Explanation:
as the population size gets
The growth rate tends to
closer to the carrying capacity.
Answer:
As population size approaches the carrying capacity of the environment, the intensity of density-dependent factors increases. For example, competition for resources, predation, and rates of infection increase with population density and can eventually limit population size.

The following RNA strand was produced: 5 AUG GCG UUU 3 Which of the following DNA strands could have been the template for this RNA? Choose 1 answer: A 3 TAC CGC AAA 5' 3' CGT TAT GGG 5' 3' AUG GCG UUU 5' 3' UAC CGC AAA 5
Answer:
A
Explanation:
Each nucleotide is appropriately paired according to the A-U/T-A and C-G pairing rules, so these are complementary strands.
The DNA strand that could have been the template for RNA 5' AUG GCG UUU 3' is 3' TAC CGC AAA 5'.Thus, the correct option is A.
What is a Template strand?A template strand may be defined as the DNA sequence that can duplicate itself during the process of mRNA synthesis. During this process, the cell utilizes a non-coding/antisense DNA sequence as a template to construct mRNA.
The production of the mRNA strand is done with the help of complementary base pairing with that of the template strand. In this process, A is bound to T and vice versa, while C is bound to G and vice versa.
In mRNA, the Thymine (T) is replaced by Uracil (U). According to Chargaff's rule, the amount of ADENINE is equal to THYMINE, while the amount of GUANINE is equal to CYTOSINE.
Therefore, it is well described above.

Please choose the answer that best completes the blanks of this sentence in the correct order. The ______ plate method involves spreading an inoculum onto the surface of a plate in a pattern that results in isolated colonies in some areas of the plate after incubation, whereas the ______ plate method involves diluting an inoculum into several melted agar tubes and then adding their contents into plates for solidification and incubation.
Answer:
streak, pour
Explanation:
The streak method is the most popular technique used to isolate specific bacteria from a sample containing different microorganisms. In this technique, a sterile loop is employed to obtain an uncontaminated microbial culture. Colony picking refers to the process where colonies of pure bacteria are selected in order to duplicate them by transferring them into new agar plates. Moreover, the pour plate method is the most popular technique employed to count the number of colony-forming bacteria (i.e., bacteria/ml) in a specimen. The pour plate method consists of dropping the sample on a sterile plate and subsequently molten-cooled agar is then poured into the plate and mixed well with the inoculum.
Answer:
streak, pour
Explanation:
The streak plate method involves spreading an inoculum onto the surface of a plate in a pattern that results in isolated colonies in some areas of the plate after incubation, whereas the pour plate method involves diluting an inoculum into several melted agar tubes and then adding their contents into plates for solidification and incubation.

What do you think? Are polar bears doomed to go extinct or do you think they will survive?
Answer:
Polar bears will go extinct by the end of the 21st century.
Explanation:
Polar bears live at the North Pole. Due to global warming, the ice at the poles is melting at an alarming rate. Soon there won't be any glaciers. Without the ice Polar bears will lose their home. The climate on Earth is becoming warmer day by day. So even if the Polar bears survive they will not be able to adapt to the warmer climate. Thus leading to their extinction.

: Is a human leg prosthetic an example of science or technology? Explain your answer.
QUICK!!!! ANSWER PLEASE WITH EXPLANATION TOO!!!
Answer:
This would be an example of technology.
Explanation:
Artificial limbs, or prostheses, are used to replace a missing body part which may have been lost due to trauma, disease or congenital defect. The type of prosthesis a person can use is dependent on the individual, including the cause of amputation or limb loss, and the location of the missing extremity. These come in all shapes and sizes, for whatever you need.
Have a nice day!
Answer:
A technology, since the actual prosthesis is a human creation that solves a problem. Science is nothing physical. It is the combination of laws and theories that explain our universe and helps us make decisions. We don't really invent science, we describe it.
Science is ideas. Technology is human creations.
Science generally underpins all new technology.
In your human leg prosthesis example science is crucial in choosing (or developing) suitable materials for construction of the prosthesis. The material must be relatively stable, not break down into toxic substances and have good durability. Knowledge of human Biology is also important if you want to start replacing human body parts.
Basically chemistry and biology are important in the prosthesis development. There is also probably physics regarding tensile strength requirements.
The actual end result of the human prosthesis is a technology which solves a problem of degraded human parts.
So to reiterate, it is a technology.
