Which of the following is a characteristic of many eukaryotes?
a. Many eukaryotes have no DNA
b. Many eukaryotes have many cells
c. Many eukaryotes have no cell membrane
d. Many eukaryotes have DNA in cytoplasm
Answer:
c
Explanation:
The statement that represents a characteristic of many eukaryotes is that many eukaryotes have many cells. Thus, the correct option for this question is B.
What do you mean by Eukaryotes?Eukaryotes may be defined as the type of living organisms that significantly have a well-defined nucleus along with other membrane-bound cell organelles. These organisms have a complex level of compartmentalization.
According to the context of this question, almost all eukaryotes have DNA in their nucleus. This is because it is considered its genetic material. So, options A and D are eliminated.
The cell membrane is the characteristic feature of every eukaryote because this membrane separates the inner environment of the cell from external conditions. So, option C is eliminated as well.
Therefore, the statement that represents a characteristic of many eukaryotes is that many eukaryotes have many cells. Thus, the correct option for this question is B.

What is the BEST explanation that accounts for the climate in tropical areas near the equator?
A) When the air is cooled it can absorb more moisture, and it tends to rise. Thus air near the poles, heated by the direct rays of the sun, absorbs moisture and rises.
B) When the air is warmed by the sun it can absorb more moisture, and it tends to rise. Thus air near the poles, heated by the direct rays of the sun, absorbs moisture and sinks.
C) When the air is cooled it can not absorb as much moisture, and it tends to sink. Thus air near the equator, heated by the indirect rays of the sun, absorbs no moisture and sinks.
D) When the air is warmer by the sun it can absorb more moisture, and it tends to rise. Thus air near the equator, heated by the direct rays of the sun, absorbs moisture and rises. Higher in the atmosphere the air cools again, forming clouds that produce rainfall.
Answer:
D
Explanation:
The equator is hit with direct sunlight, and is known to be very humid and have lots of rainfall.
The air in the thermosphere becomes thinner and thinner until it fades into space. True or false
Answer:
Well to be honest there are no unmistakable separating lines. Each layer mixes into the layer above it and the layer underneath it. Researchers are certain that the air becomes thinnerand more slender farther from the Earth's surface, until it at long last blurs off into space.

Which of the following does NOT describe vacuoles?
both plants and animals have vacuoles
they are the largest organelle in plant cells
they store water in plants and help give them structure
they are the place where cell respiration takes place
Answer:
they are the place where cell respiration takes place
Explanation:
Cellular respiration is a series of metabolic reactions used by the cell to create energy (ATP), these reactions occur partially in the cytoplasm, but mostly in the mitochondria. On the other hand, vacuoles store water in plants and help give them structure, are the largest organelle in plant cells, and both plants and animals have them. Therefore the answer is, they are the place where cell respiration takes place.
In real life, sequencing data is never as clean and clear as the sequencing data presented here. Typically, sequencing machines do not read eDNA sequences perfectly, occasionally mistaking a C for a T, for instance (though this is often <1% of the time). Additionally, there will even be some variability of the barcode among individuals of the same species! How can sequences without 100% identity to a reference still be useful for biodiversity assessment
Answer:
by using consensus sequences and complementing DNA barcoding data with other sources of information (e.g., morphological, and ecological data)
Explanation:
DNA barcoding refers to the taxonomic method used to identify and classify species by comparing DNA sequences. Some of the most used barcoding genes include the 16 subunit (16S) of the ribosomal RNA (rRNA) gene in prokaryotes, the Cytochrome c Oxidase I (COI) gene in animals, the Internal Transcribed Spacer (ITS) sequence in fungi and the RuBisCO gene in plants. A good gene for DNA barcoding purposes must exhibit intraspecific variability, conserved regions in order to synthesize appropriate PCR primers, and the sequence need to be short in length (100 to 1000 bases). The main problem associated with this identification method is the confidence value between genetic sequences. For example, when COI sequences are identical, there is a 6 percent of chance that these sequences belong to different species. On the other hand, the percentage of intraspecific variability among DNA barcoding sequences is variable, even among closely related species. This problem, as well as bioinformatic errors related to sequence reads, can be partially overcome by aligning genetic sequences (including outgroups) in order to obtain consensus sequences. Moreover, taxonomists reasonably argue that DNA barcoding data should be complemented with morphological and ecological data in order to achieve accurate species identification.

Caenorhabditis elegans is a species of soil-dwelling nematode (roundworm) that feeds on soil bacteria, including Bacillus thuringiensis.
a. True
b. False
Answer:
b. False
Explanation:
Caenorhabditis elegans is a well-known species which is widely used in genetic experiments (i.e., it is a model organism). C. elegans is a soil nematode that eats bacteria, but its survival depends on the ability to distinguish toxic from non-toxic ones. C. elegans cannot feed Bacillus thuringiensis because this bacterium produces a toxin Bt protein that damages its gut, thereby producing the death of this nematode. Interestingly, it has been proposed that Bt toxin pathways might be exploited for the design of new generation nematicides.
How do elephants warn their family groups of a dangerous predator in their habitat?
A. They use their trunks to make loud sounds.
B. They stomp their feet to create noise.
C. They use their tusks to kick up dirt.

Answer:
How do elephants warn each other?
When they're excited, scared or happy, elephants make the trumpeting sounds you're probably familiar with. They vocalize in other, more complicated ways, too — low-pitched rumbles outside our range of hearing. At less than 20 hertz, these infrasonic calls are often used to alert each other to danger.

Antibiotic resistant bacteria are becoming more and more prevalent, leaving us in desperate need of novel antimicrobial compounds to replace the drugs that are now obsolete in our hospitals and medical clinics. A high throughput screen of 700,000 compound library has allowed you to identify one molecule capable of killing extensively drug resistant tuberculosis at concentrations 1000X lower than currently used therapeutics. The only problem is, you don't know the molecular target. Develop an experimental strategy to identify the molecular target of your new antibiotic. Make sure to use some of the techniques described in the chapters covered throughout Units 1-6, and be creative. There isn't one correct answer!'
Answer:
Explanation:
We know the molecules equipped for killing broadly drug-resistant tuberculosis. This requires that we build up an experimental test system to distinguish the molecular target of your new antibiotic.
These steps include:
Gather proteomics data of tuberculosis and gather structural data of all proteins inside it.
At that point perform molecular docking with the molecule you as of now have.
This can yield the molecular target for the new antibiotic.

and actually are rarely found.
True
False
Answer:
The correct answer is - false.
Explanation:
The ANS is a system consider as the visceral motor system, however, the afferent pathways are the system that is used to flow the signals to the control center from taking from the receptor and are very essential for the homeostasis communication of the nervous system.
This pathway involves the neurons with the signals to the spinal cord and the brain as sensory data. This pathway is very common to provide communication between the receptor and spinal cord.
