Which is the difference between an antibiotic and an antiviral?
Answer:
There are no options in this question, the options are as follows:
A. Antibiotics build up immunity, and antivirals increase white blood cells.
B. Antibiotics treat the symptoms, and antivirals destroy the causing organism.
C. Antibiotics are in liquid form, and antivirals are in mist form.
D. Antibiotics treat patients who have Staphylococcus, and antivirals treat patients who have the flu.
The answer is D
Explanation:
Specific drugs are used to curb infection or diseases caused by specific pathogens. An infection can be caused by either bacteria, virus or fungi. Considering their different mechanism of infection, viral infections are treated with the use of ANTIVIRAL DRUGS while bacterial infections are treated with the use of ANTIBIOTICS.
According to this question, staphylococcus is a bacterial genus and hence, patients with staphylococcus can be treated with antibiotics while flu is a viral disease, hence can only be treated with antivirals.
Answer:
A. Antibiotics build up immunity, and antivirals increase white blood cells.

Answer:
have variation that can be passed from one generation to the nextsurvive longer than another organismhave adaptations to their environment. have differential reproductive success.Explanation:
Naturla selection is the survival and reproduction of individuals due to different phenotypes. The naturla selection represents a mechanism of evolution and changes in traits of species.In order for natural selection to occur, organisms must :
have a variation that can be passed from one generation to the next.have differential reproductive success.Natural Selection is a mechanism of evolution that occurs when there is a heritable variation for a trait and individuals with one version of the trait have greater reproductive success than do individuals with a different version of the trait.
In order for natural selection to occur, three conditions must be met:
There must be variation for the particular trait within a population.The variation must be inheritableIndividuals with one version of the trait must produce more offspring than those with a different version of the trait.Thus,

Explain how homologous and the fossil records support evolution.
Thanks so much!!!
Answer:
Los fósiles, una prueba de la evolucion. El estudio de los fósiles nos da una idea muy directa de los cambios que sufrieron las especies al transformarse unas en otras; existen muchas series de fósiles de plantas y animales que nos permiten reconstruir cómo se fueron adaptando a las cambiantes
Explanation:
Answer:
homologous: have identical position, value, or structure
Fossils: In the oldest rocks area unit fossils of the best organisms and within the newest rocks area unit fossils of additional advanced organisms.
Explanation:
The evolution theory is supported by multiple sorts of evidence: homologous structures show common ancestry, whereas similar selective pressure will manufacture similar variations. analogous structures (beneficial features).
In the oldest rocks area unit fossils of the best organisms and within the newest rocks area unit fossils of additional advanced organisms. This supports Darwin's organic process theory, whereby straightforward life forms {progressively|increasingly|more and additional} evolved into more advanced. Proof of adolescence forms comes from fossils.

Which is an environmental factor that affects skin color in humans?
O number of genes inherited
O amount of sunlight absorbed
O number of linked genes
O amount of food consumed
Which is an environmental factor that affects skin color in humans?
O number of genes inherited
O amount of sunlight absorbed
O number of linked genes
O amount of food consumed
ANSWER:-AMOUNT OF SUNLIGHT ABSORBED.
Number of gene for color of the skin is same in all the human beings and also it's a genetic factors is there will be any absence of gene due to its deletion AMOUNT OF SUNLIGHT it is variable in variable reasons which is a imp factor for the color in variation in earth. In regions near to the equator have high amount of the light so they have darker skin color then the people near the poles as there is less amount of light .Number of gene inherited is also same for each and every individual for single species for human which is 378 gene loci and if there is any variation in number due to any genetics disorder it would be a genetic factor again.amount of food consumed is different for different people with same color in same region as it only depends on the work which is done by the individual in the society for its existence. though it is a environmental factor bit it didn't effect color of the species.SO ACCORDING TO ABOVE DETAILS WE CAN CONCLUDE (2) AMOUNT OF THE SUNLIGHT IS THE ENVIRONMENTAL FACTOR WHICH IS RESPONSIBLE FOR THE COLOR OF THE SKIN IN HUMANS
What goes on during interphase?
Explanation:
During interphase, the cell grows (G1), replicates its DNA (S) and prepares for mitosis (G2). ... Interphase is the 'daily living' or metabolic phase of the cell, in which the cell obtains nutrients and metabolizes them, grows, replicates its DNA in preparation for mitosis, and conducts other "normal" cell functions.

Iron-55 has a half-life of 3 years. How much of a 40 gram sample will remain after 12 years? A. 0 grams B. 4 grams C. 2.5 grams D. 20 grams
Answer:
[tex]\boxed {\boxed {\sf C. \ 2.5 \ grams }}[/tex]
Explanation:
We are asked to find how much of a 40 gram sample remains after 12 years.
Iron-55 has a half-life of 3 years. Therefore, after 12 years, 4 half-lives have been completed.
12 years/3 years = 4 half-livesEvery time a half-life is completed, half of the sample's mass decays. Remember we start with a 40 gram sample.
1 half- life: 40 g / 2 = 20 g 2 half-lives: 20 g / 2= 10 g 3 half-lives: 10 g / 2 = 5 g4 half-lives: 5 g / 2 = 2.5 gThere is also a formula that can be used to solve this problem.
[tex]A= A_o(\frac {1}{2})^{\frac{t}{hl}[/tex]
Where A₀ is the initial amount, t is the time, and hl is the half-life.
We know 40 grams is the inital amount, 12 years is the time, and 3 years is the halflife.
A₀= 40 g t= 12 hl= 3[tex]A= 40 \ g (\frac{1}{2})^\frac{12}{3}[/tex]
[tex]A= 40 \ g (\frac{1}{2})^4[/tex]
[tex]A= 40 \ g * 0.0625[/tex]
[tex]\bold {A= 2.5 \ g}[/tex]
After 12 years, 2.5 grams of Iron-55 will remain.

When can exponential growth happen?
O A. When there are limited resources
O B. When the death rate is high
Han
O C. When carrying capacity is reached
O D. When there is no competition
Answer:
D. When there is no competition
Explanation:
If there is no competition in a population, exponential growth can occur.
Without competition, resources are not limited and a population can grow rapidly.
With limited resources, a high death rate, and a reached carrying capacity, population growth is strongly limited and cannot grow at an exponential rate.
So, answer choices A, B, and C are all incorrect.
The correct answer is D. When there is no competition

A researcher is testing young children to see if they can learn to associate a red circle with an event that the child enjoys. She sets up an experiment where a toy bear dances. The infants predictably love the toy bear and stare at it when it makes noise and dances. She then trains the child by showing a big red circle on a screen in front of the child and, immediately after that, the bear appears and dances off to the side. The bear is only visible right after the red circle appears and the child must turn his or her head to see the bear.
In this study, the unconditioned stimulus is ____________ baby does not turn head baby turns head dancing bear red circle , the unconditioned response is the __________ dancing bear baby does not turn head red circle baby turns head , the conditioned stimulus is the _________ dancing bear baby turns head baby does not turn head red circle , and the conditioned response is the ______ baby does not turn head red circle dancing bear baby turns head . The neutral stimulus is the _______ baby turns head dancing bear red circle baby does not turn head and the response to the neutral stimulus is the 6 _______
Answer: unconditioned stimulus = dancing bear
unconditioned response = baby turns head
conditioned stimulus = red circle
conditioned response = baby turns head
neutral stimulus = red circle
response to neutral stimulus = baby does not turn head

During a recent hurricane, 25 individuals of the same butterfly species were blown onto a barrier island in southern Florida. Prior to this event, this species did not inhabit the island, but with the ample vegetation on the island and a lack of predators, the displaced individuals were able to survive and reproduce. When the butterflies initially arrived on the island, they did not have to compete for food or space. What type of population growth did they likely exhibit
Answer: Exponential
Explanation:
The main requirement for the population of a species to grow is food. When there is food, a organisms that are born will be able to live longer because food will be able to sustain them.
This is what happened with humans during the Neolithic Revolution when we began farming.
The general trend is that the more food that is available, the higher the population growth. When these butterflies arrived and found no competition for food, their population would increase in the highest way possible which is exponentially because there would be plenty of food to go around.
Answer:
Exponential growth
Explanation:
Without any competition for food or space, the butterfly species likely experienced exponential growth.
The lack of competition would have allowed the population to flourish, as they would have excess amounts of resources, food, space, and other limiting factors.
So, they most likely exhibited exponential growth.
What type of cells are simple animal and plant cells?
Answer:
both animals and plants are eukaryotic cells
Answer:
Animal cells have centrosomes (or a pair of centrioles), and lysosomes, whereas plant cells do not. Plant cells have a cell wall, chloroplasts, plasmodesmata, and plastids used for storage, and a large central vacuole, whereas animal cells do not.
Explantion
Animal cells
Animals are made up of millions of cells. Animal cells have an irregular structure and are made up of four key parts:
Nucleus – This contains genetic material (DNA), and controls the cell's activity.
Cell membrane – A flexible layer that surrounds the cell and controls the substances that enter and exit.
Cytoplasm – A jelly-like substance where the chemical reactions happen.
Mitochondria – This is where energy is released from the food molecules
Plant cells
Plants are also made up of millions of cells. Plant cells have a nucleus, cell membrane, cytoplasm and mitochondria too, but they also contain the following structures:
Cell wall – A hard layer outside the cell membrane, containing cellulose to provide strength to the plant.
Vacuole – A space inside the cell that is used to store substances and help the cell keep its shape.
Chloroplasts – Structures that contain the green pigment chlorophyll, which are a key part of photosynthesis.

Why does climate change affect so many things?
Answer:
These have been caused by many natural factors, including changes in the sun, emissions from volcanoes, variations in Earth's orbit and levels of carbon dioxide (CO2). Global climate change has typically occurred very slowly, over thousands or millions of years.
Explanation:
According to me there are several causes of climate change, but all the problems are based upon a major problem which is over population. Either it is deforestation, any kind of pollution, global warming or whatever it is, all these problems are inter-linked and all are due to increasing population.
What is a disadvantage of using a space-filling model to show a chemical compound?
Answer:
Explanation:
The appropriate answer is 'space filling models do not identify the number and type of bonds'. A space filling model is one type of three dimensional (3D) molecular model used to represent molecules of different chemical compounds. The structure of this type of arrangement shows that, for example, two elements are bonded but it does not show if it is a single, double or triple bond.
1 Reproduction is an important characteristic of living organisms.Explain
Answer:
Reproduction is one of the most important characteristics of living beings, because -
- The existence of any species is dependent on the reproduction because no living being is immortal.
After death of a being of one generation,the existence of that died being is completed by the newborns of the next generation.
And,the birth of newborns of next generation is only possible by the reproduction.
- The variation and mutation in the biological characteristics is often necessary which is only possible by reproduction through many generations.
- When a living being becomes old, it's become unable to do normal tasks like collection of food, finding shelter etc,at that moment,the newborns of next generation do the necessary jobs.
And as mentioned before,these newborns are only possible due to reproduction.
