The DNA in some lung cells was damaged by the carcinogenic compounds in tobacco and apoptosis was initiated. Which of the following is the best way for the damaged lung cells to send a message to their neighboring cells that they need to increase the production of DNA repair enzymes or start apoptosis as well?

A) They should send signaling molecules into the bloodstream.
B) They should send signaling molecules through the gap junctions.
C) They should send signaling molecules across a small extracellular space.
D) They should send signaling molecules by secreting them into the local environment.

Answers

Answer 1

Answer:

C) They should send signaling molecules across a small extracellular space.

Explanation:

To send a message to nearby cells, signal molecules only need to cross a small amount of space. Bloodstream (choice A) is used for long-distance communication, choice D is too vague, and choice B is used only for cells that are directly touching each other.

Answer 2

Answer:

B) They should send signal molecules through the gap junctions.

the answer is Plastic reduces the transfer of thermal energy to hands holding the utensils.

Explanation: I  took the test  again  and I got it right

Plastic reduces the transfer of thermal energy to hands holding the utensils which is why it is best used.

What is Utensil?

This can be defined as a small hand held tool used for food preparation. Metal is a good conductor of heat while plastic is a poor conductor.

Plastic is therefore used as it reduces the transfer of thermal energy to hands holding the utensils.

The correct order of events in protein synthesis in eukaryotes is:
A. DNA is transcribed to amino acids in the cytoplasm, translation of RNA to a protein by transfer RNA in the cytoplasm
B. DNA is transcribed to an RNA molecule in the nucleus, translation of RNA to a protein by ribosomes in the cytoplasm
C. DNA is translated to an RNA molecule in the nucleus, transcription of RNA to a protein by ribosomes in the cytoplasm
D. RNA is directly translated to amino acids sequences in the cytoplasm
E. Mitochondrial DNA is transcribed to ribosomal RNA in the cytoplasm, translation of RNA to a nucleotide in the cytoplasm

Answers

Answer:

B. DNA is transcribed to an RNA molecule in the nucleus, translation of RNA to a protein by ribosomes in the cytoplasm

Explanation:

Protein synthesis in eukaryotes follows the central dogma of Biology which states that DNA is transcribed to RNA, which is then translated to PROTEIN. DNA is the genetic material in living organisms that stores genetic information in the NUCLEUS of eukaryotic cells. The DNA then undergoes the process of transcription, which is the first stage of protein synthesis, to form mRNA.

The mRNA transports the genetic information out of the nucleus into the cytoplasm, specifically the ribosomes, where the process of TRANSLATION occurs to form PROTEINS. Hence, the correct order is: DNA is transcribed to an RNA molecule in the nucleus, translation of RNA to a protein by ribosomes in the cytoplasm

9. Knowing what you know about how a substance travels in
diffusion, in order for oxygen to leave the alveoli and enter the
blood, there would be a [ HIGHER or LOWER] concentration of
oxygen in the alveoli compared to the blood.

Answers

Answer:

Higher

Explanation:

Molecules such as oxygen move from a higher concentration to a lower concentration across a semi-permeable membrane. This process is called simple diffusion.

Therefore, for oxygen to leave the alveoli and enter the blood, there would need to be a higher concentration of oxygen inside the alveoli and a lower concentration of oxygen in the blood.

In order for oxygen to leave the alveoli and enter the blood, there would be a higher concentration of oxygen in the alveoli compared to the blood.

Diffusion is the process by which compounds or substances move from a

region of higher concentration to that of a lower concentration. This helps to create an equilibrium in the concentration of the substance to prevent cell death due to shrinking etc,

The alveoli is found in the lungs which is the organ of respiration and the

oxygen present is usually in higher concentration and moves to regions of

low concentration in the blood.

A student claims that electronegativity is not related to the
concept of polarity. Use water as an example to provide
reasoning to refute the student's claim.
PLEASE HELP!

Answers

Answer:

Please find the explanation below

Explanation:

Polarity of a molecule is the function of the difference between the electric charges of two atoms that make up the molecule. This polar nature is greatly influenced by the ELECTRONEGATIVITY, which is the ability to attract electrons, of the atoms involved. For example, using water molecule, H2O, as a case study.

Water is known to be a highly polar molecule due to the electronegativity values of the atoms that make up its molecule. Oxygen atom is a more electronegative atom than hydrogen, hence, it pulls more electrons towards itself, leaving the hydrogen atom more electropositive. This forms the difference in the electrostatic force between oxygen and hydrogen, making water POLAR.

HENCE, the student is wrong to have said electronegativity is not related to the concept of polarity.

Roger is at a wedding reception where he has been introduced to over 50 guests whom he has never met. He would like to remember as many names as possible. Describe the role that sensory storage, short term memory and long term memory play for roger in this situation.

Answers

Answer:

In this situation, the role of sensory storage would be-

as he enters at reception the smalls, images, would be sensed by him and make its burn the memories in his brain.

Short-Term memory helps in make him remember by the names associated with the small gesture, movement, mannerisms made by them. For example, sam stutters can be remembered as stutter Sam.

Long-Term memory helps in building memory by long haul with help of scenery by relating individuals he already know before the reception and whenever see them mind reminds the name.

The  ability of the brain to acquire information, feelings, and  processed, keep, and recollect this for the subject is called memory.

The threes stages of memory are

sensory storage or memory short term memory and long term memory.

The ability of Roger to  keep memory of the names with these three stages, depends on how pays attention and his ability  to process information.

The sensory storage depends on the five sense to send  information to his brain. Thus, Roger needs to pay attention to the faces,(iconic memory) voices (echoic memory),  feel or touch (Haptic Memory)  and (Smell) aroma of perfumes when been introduced to the guest.

 These information are retains for few seconds after the guest( the sensation has gone).Thus with this ,he sees every guest as collective set of people without  and not as individual. For his brain to process the information as individual  he needs to network with the Short memory.

The short memory  is the type that retain the information( the names ,voices and touches) of the guests he was introduced to at that present moment. He needs to pay attention and try to retain these sensation to prevent them from been forgotten. These  sensations are  retain  tentatively until the  information is processed. It is these processed information that are stored  by his brain ,and not the sensory signals like in the sensory.

In order for the processed or interpreted information to be stored and used for longer time, and recalled when needed, these are transferred to the long term memory. This is subdivided into  two types; explicit  and implicit memory.

He will makes use of the explicit memory because the stored names can  be recollected consciously after storage when the 3 types of memories are merged. Unlike the  implicit that can not be access consciously.

With the capture of the image of the guest with sensory memory, temporary store  the processed names  with short term and   stored this  for future, Roger should  be able to remember these names.
