Neurons transmit signals to the central nervous system. The brain processes this information to initiate a response. Two neurons communicate with each other through the ( axon , dendrite, synapse) . The ( cerebrospinal cord, glial cell, neurotransmitter) is released at the site to initiate action potential and carry the signal through the body.
Answer:
synapse
neurotransmitter
Explanation:
Neurons are the basic units for the transmission of signals to the central nervous system. The two neurons are connected through the syanpse. Synapse is the space or junction between two nerve cells, or neurons.
The neuron receives signals through dendrites and two neurons communicate with each other through a chemical called neurotransmitter, which is released at the end of a nerve fibre and carry the signal through the body.
Hence, the correct answers are synapse and neurotransmitter.
Two neurons communicate with each other through the synapse which contains a chemical known as a neurotransmitter which is released at the site to initiate action potential and carry the signal through the body.
Neurons are specialized cells whose functions are to receive and transmit information from the external environment to the internal environment and vice versa.
They are the basic units of the brain and the nervous system.
The nervous system consists of two parts:
The central nervous system made up of the brain and spinal cord, and The peripheral nervous system consisting of the cranial nerves, the spinal nerves, the sympathetic nervous system, and the parasympathetic nervous system.Neurons transmit signals to the central nervous system. The brain processes this information to initiate a response.
Two neurons communicate with each other through the synapse. A synapse is the space or junction between two nerve cells, or neurons.
A chemical called a neurotransmitter is present at the end of the neuron before the synapse known as the presynaptic end.The neurotransmitter is released into the synapse via vesicles known as synaptic vesicles.The synaptic vesicles fuses with the membrane of the second neuron and the neurotransmitter is released initiating another action potential and carry the signal through the body.Therefore, two neurons communicate with each other through the synapse which contains a chemical known as a neurotransmitter which is released at the site to initiate action potential and carry the signal through the body.

Which of the following is a human-related release of greenhouse gases?
O A. Wild animal respiration
OB. Volcanic eruptions
O C. Intensive agriculture
O D. Solar cycles
It’s A
Answer:
C
Explanation:
I'm pretty sure it's actually C and not A. It's asking for human-related release from greenhouse gases. Humans don't cause volcanic eruptions and aren't in control of wildlife's respirations. The solar cycles has to do with the magnetic flux that rises to the surface of the sun and lasts 11 years. Intensive agriculture increases pollution which harms the environment.

Answer:
Meiosis is the mechanism used for producing gametes in multicellular organisms whereas it does
unicellular organisms.
Explanation:
Meiosis is a kind of cell division used mainly by sexually-reproducing organisms, whether unicellular or multicellular, to produce gametes i.e. meiosis only occurs during gamete formation.
In sexual reproduction, gametes must fuse in a process called fertilization. This gametes, however, must each possess half of the chromosome number of the individual organism. Meiosis is the process that ensures that the chromosome number of the gametes is reduced by half i.e. diploid (2n) to haploid (n).
Therefore, meiosis is the process of gamete formation in sexually-reproducing unicellular or multicellular organisms.

What can a person do to limit exposure to X-rays?
wear sunblock
avoid cigarette smoke
wear a protective vest avoid chemicals
X-rays are a form of indirectly ionizing radiation, and it can be really nocive to the humans health, so limiting the exposure is always a priority.
Here the correct option is wearing a protective vest.
-------------------------------------
X-rays are a form of radiation that is indirectly ionizing. Remember that ionization is what causes damage to our cells, so is better to avoid exposures to these types of radiation.
Now, X-rays are strong enough that they can penetrate a lot of common materials (like wood, plastic, etc.) And once it enters in your body, the chain of reactions that starts can't be stoped by external means.
So what you need to do is limit the exposure as much as you can. Ideally, you shouldn't be near a source of X-rays, but if there is no other option, you should use protection against radiation.
It comes in different forms depending on what the application is, for example, there are led screens that you can use to put between you and the source, and these will reduce drastically the fluence (flux of photons) that gets to you.
Similarly, there are protective vests also made in part of led or other high atomic number materials, that absorb the photons and protect you.
So here the correct option is to wear a protective vest, from the given options, is the only one that will protect you from the X-rays.

g 1 molecule of glucose is catabolized to pyruvate and then acetyl-coA. All the acetyl-coA enters the citric acid cycle. How many molecules of NADH are produced from the citric acid cycle only (do not include NADH from glycolysis or the pyruvate dehydrogenase complex in your calculation.) You must answer as a number i.e if you think the answer is 12, you must enter 12, not twelve.
Answer:
6NADH
Explanation:
In the kreb's cycle NAD is reduced during the reduction of 6-carbon citrate to 5 carbon Alpha-Ketoglularate.
The second is produced during the conversion of 5carbon alpha ketoglutarate to succinate. Lastly in the conversion of fumirate to oxoloacetate;another NADH is formed.
However, since two pyruvate enters the Kreb's cycle therefore 6NADH(three NADH per cycle of Citric) are produced for each molecule of glucose that is broken down from glycolysis.
Remember,each glucose molecule goes through 2 cycles of Kreb.
Futhermore co-enzyme FADH2 are also produced,with 2 molecules per 1 glucose.
These Co-ezymes transfer hydrogen ions,into the matrix of the mitochondria,where is is splits to protons and electrons.
The electrons formed the ETC,which produce PMF for transporting protons into the intramembranes for electrochemical gradients needed to generate energy for ATP s synthesis,by ATP synthase.

Mutations in region B and region D give the same results - when either of these regions is mutated, the operon is expressed under all conditions (called constitutive expression). You hypothesize that region B is the operator region and that Region D is the repressor protein. To test your hypothesis, you create two partial diploid lines by introducing a F' plasmid with a wild-type lac operon: Strain 1: F' A B C D E / A B- C D E Strain 2: F' A B C D E / A B C D- E What experimental results would be predicted by your hypothesis
Answer:
As it is given in the question that region D is the repressor protein and operator region is region B then the The repressor region D form a protein that will bind to the operator region B and leads to inhibition of the transcription. So, the repressor protein will not repressed a mutant operator and the lac gene will express itself constitutively.
Strain 1: F' A B C D E / A B- C D E
In this strain the mutant opertor gene is present so, it will not repressed by F' as it will not be able to bind. Hence, the lac gene expression is constitutive.
Strain 2: F' A B C D E / A B C D- E
In this strain there is two protein produced by the F' plasmid mutated repressor protein, and a non-mutated repressor protein. As we know mutated repressor will not bind to operator gene and still expression will take place but here a extra not mutated non-mutated protein is present and the repressor protein from F' will bind to the operator region B and thus repress the expression of gene in it.

Which of these is most likely to cause increasing numbers of severe weather
events?
A. Slowing of the thermohaline circulation
ОО
B. Increasing salinity
c. Decreasing temperature
O D. Falling sea levels
SUBMIT
Answer: What is most likely the cause of the increasing numbers of severe weather events is A. the slowing of the thermohaline circulation.
Explanation: Thermohaline circulation is hard to explain, but it is important in giving heat to the polar regions. The six main components that determine the weather are temperature, atmospheric pressure, cloud formation, wind, humidity, and rain. A small change in any of these components can result in an entirely new weather pattern. As mentioned in the question, slowing the thermohaline circulation would very likely increase the number of severe weather events. What I just said, I took the test, and the answer is A.
Slowing of the thermohaline circulation is most likely to cause increasing numbers of severe weather events. Thus, the correct option will be A.
What is Thermohaline circulation?Thermohaline circulation is a part of the large-scale ocean circulation which is driven by the global density gradients that are created by the surface heat and freshwater fluxes.
Thermohaline circulation generally plays an important role in the process of supplying heat to the polar regions. Therefore, it influences the rate of sea ice formation near the poles region, which in turn affects other aspects of the climate system such as the albedo, and thus also include solar heating, at high latitudes.
Therefore, the correct option will be A.

) Recall what you know about crossing over, independent assortment, and random joining of sex cells during sexual reproduction.
Answer:
Crossing over is the process of interchange of genetic information among non-sister chromatids of homologous chromosome pairs during meiosis (specifically during synapsis in prophase I). During this process, the synaptonemal complex enables the interchange of chromosome fragments between non-sister chromatids through crossing over. Moreover, in sexual reproduction, the zygote diploid cell can be generated by the random joining of fully differentiated haploid gametic cells (male and female gametes). The combination of random joining with the phenomenon of crossing over is known to considerably increase the genetic variation of the resulting offspring. After zygote formation, the successive cycles of cell divisions during embryonic development will develop an organism that during its adult stage will reproduce via sexual reproduction.

Phytoplankton, shown on the left in the image below, are microscopic organisms that can be found in freshwater and salt water environments. They perform photosynthesis to get energy and act as an important food source for larger organisms, such as the whale that is shown on the right. Phytoplankton A large whale. Which characteristic describes the whale but not its food source, the phytoplankton? The whale is heterotrophic. The whale has cell walls. The whale is unicellular. The whale is a prokaryote.
Answer:
The whale is heterotrophic.
Explanation:
Energy is needed by organisms to perform their life functions. Organisms, in nature, feed on one another for energy source. Some organisms are, however, capable of synthesizing their own food or energy source via a process called photosynthesis. This is the case of the phytoplankton in the question. These organisms are, therefore, called AUTOTROPHIC ORGANISMS or PRODUCERS.
On the other hand, some organisms are incapable of this self-production of energy source. Hence, they rely on other organisms for it. These category of organisms are called HETEROTROPHIC organisms, which is the category the large whale fall into due to its dependence on phytoplankton for energy source.
