Name 2 reasons why bacteria are resistant to antibiotics?
Answer:
Antibiotic resistanceAntibiotic resistance is accelerated when the presence of antibiotics pressure bacteria and fungi to adapt. Antibiotics and antifungals kill some germs that cause infections, but they also kill helpful germs that protect our body from infection. The antibiotic-resistant germs survive and multiply.

Examine the words. impulse, presynaptic cell, neurotransmitters, receptors, postsynaptic cell what idea can be described using all the words listed? the difference between the somatic and autonomic nervous systems the transfer of information from one neuron to another the difference between the central and peripheral nervous systems the flow of information within a neuron
The idea it can describe is that it is the transfer of information from one neuron to another.
Transfer of informationThe nervous system is part of the body systems that helps in the transfer of information from nerve to nerve and from nerve to muscle tissues.
The presynaptic nerve is the nerve that sends the information that is to be conveyed in form of action potential impulses.
The impulses led to the release of neurotransmitters from the terminal of the presynaptic nerve to the synapse. This binds to the receptor if the postsynaptic cell which receives the message.

This text is from the transcript of the video "Adélie Penguins" from the NOAA web site Ocean Today.
Studies show that since 1950, the western Antarctic peninsula winter has warmed 11 °F, five times the global average. This warming trend is decreasing the amount of sea ice that forms and shrinking the habitat where young krill grow. This puts the Adélies’ food supply and their breeding success at risk. Complicating matters, Gentoo and Chinstrap penguins, which favor conditions with less sea ice, are taking over some of the Adélie colonies in this area.
Which statement is supported by both the text and the excerpt above?
A.
All three penguin species, Chinstrap, Adélie, and Gentoo, live only on sea ice.
B.
The food supply for Adélie penguins includes both fish and krill in the Antarctic seas.
C.
Adélie penguins are dependent on the existence of sea ice for access to their food supply.
D.
Temperatures in the Antarctic have increased substantially in the last 60 years.
Answer:
C.
Adélie penguins are dependent on the existence of sea ice for access to their food supply.
Explanation: Their numbers are declining due to the loss of sea ice, so it's natural that this would be the answer.

Answer:
C.B.A.D.The prophase is the first part of cell division, where the chromosomes become visible in the form of paired chromatids.The telophase is the final phase of cell division in which the chromosomes move to opposite ends, and nuclei are formed. Although this most relates to option D, option D relates more to the anaphase, which we will talk about in just a moment.The metaphase is the second phase, where the chromosomes all line up at the equator, and they attach to spindle fibers.The anaphase, which is the phase after metaphase, is extremely nessescary for cell division. This is the process in when the chromatids move toward opposite poles, allowing the spindle fibers to shorten. When this happens, the cell splits in two, forming the two daughter cells.________________________________________________________

In recent decades, average global temperatures have increased significantly. Scientists agree that the widespread destruction of the Amazon rain forest contributes to climate change. Which mechanism might be cited to support that hypothesis?
A Deforestation causes water on the ground to reflect sunlight.
B Deforestation reduces the number of plants able to absorb carbon dioxide.
C Photosynthesis produces energy, which gives off heat.
D Plants use up energy during cellular respiration.
[tex]\qquad\qquad\huge\underline{{\sf Answer}}♨[/tex]
The main reason causing average global temperature rise is increase in amount of green house gases like Carbodioxide, and since deforestation reduces a vast number of plants, so there is lack of plants absorbing CO2 causing this whole thing.
So, according to this the Correct choice is B
The mechanism that supports the hypothesis that the widespread destruction of the Amazon rainforest contributes to climate change is Deforestation reduces the number of plants able to absorb carbon dioxide. The correct option is B.
Forests, like the Amazon rainforest, play a crucial role in mitigating climate change because trees act as carbon sinks. They absorb carbon dioxide during photosynthesis and store it as biomass. When forests are cut down or destroyed through deforestation, the carbon stored in trees is released back into the atmosphere in the form of carbon dioxide, a greenhouse gas that contributes to global warming.
The Amazon rainforest, often referred to as the "lungs of the Earth," is particularly vital in this regard because of its vast size and high biodiversity. As large areas of the forest are cleared for logging, agriculture, and other human activities, the ability of the Amazon to absorb carbon dioxide diminishes, leading to increased greenhouse gas concentrations in the atmosphere and contributing to the warming of the planet.

The study of cladistics, however, results in a phylogeny tree in which fungi are more closely related to animals than to plants.

In guinea pigs, fur length is controlled by one
gene. The Fallele generates long fur and the f
allele generates short fur. Because only one F
copy is needed to show the trait, if a guinea pig
has the FF or Ff allele combination, they will have
long fur. If they have the ff allele combination, they
will have short fur

DONE
Guinea pig 1: Long fur (FF)
Guinea pig 2 Short fur (ff)
Guinea pig 3. Long fur (FF)
The fur length of the guinea pig will depend on the alleles present in the offspring, whether they are dominant or recessive.
What are dominant and recessive traits?Dominant traits are characters which are always expressed in an offspring wherever they occur.
Recessive traits on the other hand are expressed only if the dominant trait is absent in the offspring.
In the trait for fur length in guinea pig, there are two alleles for it.
F is for long fur and is dominant f is for short fur and is recessive.Thus, the possible combination of the two alles will be:
FF for long furFf for long fur andff for short furTherefore, the fur length of the guinea pig depends on the alleles present in th offspring, either dominant or recessive.

Red-green colorblindness is a inherited disorder in which individuals have trouble distinguishes
between red and green (or brown and orange) and often confuse blue and purple hues. This
condition is usually found in males, as it is located on the X chromosome.
A man with red-green colorblindness has one brother who has normal version. From which parent did the man inherit colorblindness? Explain how you know using a Punnett square to © 2014 Vanessa Jason (“Biology Roots”
back up your answer.
Since the colorblindness is located on the X chromosome, the man must have inherited his colorblindness from his mother.
X-linked traitsWomen are XX while men are XY.
Also, the X chromosome in XY always comes from the mother.
Since the man is affected for colorblindness but his brother is not, it means that only one X chromosome of the mother is affected while the father can be affected or otherwise.
Assuming the father is free from colorblindness and the allele is represented by c:
[tex]X^cX[/tex] x [tex]XY[/tex]
[tex]X^cX[/tex] [tex]X^cY[/tex] [tex]XX[/tex] [tex]XY[/tex]
Thus, the man's genotype is [tex]X^cY[/tex] and it comes from the mother.

Which of the following best explains how a dog is able to ingest and digest food, and remove waste
products from its body?
Choose 1 answer:
A dog carries out digestion and excretion through a series of redundant systems, so if one
system is injured, another will take its place.
A dog has cells whose genetic makeup can change depending on the circumstances, such as
whether the animal is ingesting and digesting food, or excreting waste.
A dog has systems of specialized cells, such as those that make up the urinary tract and
digestive system, that help it carry out these functions.
Answer:
1st is correct
Explanation:
At its simplest, a dog's digestive system is a long tunnel that runs from their mouth to the anus. Food goes in at the mouth and travels through this tube and at various stages is broken down and either absorbed into the body or excreted as waste at the anus.
