How can poor nutrition lead to a change in trait expression?
Answer: Poor nutrition won't provide healthy amounts of energy to the body. The lack of nutritional vitamins that the body needs can lead to a change in hormonal signals, stimuli, and metabolites.
Hope this helps :)
In the overall health management, nutrition plays a very recognizable function, however, the role of genetics in nutritional impact is yet to be understood completely.
• Genetic variability in relation to nutrition may be partly accountable for differences among the individuals in metabolism, absorption of food, enzyme digestion, excretion, storage, and others.
• Nutrigenetics and nutrigenomics are the two areas of study regarding genetics and nutrition that looks for the effect of genetic variations on dietary responses, and the function nutrients perform in bioactive food compounds and expression of the gene.
• The three prime factors in nutrigenomics and nutrigenetics are ethnic diversity, malnutrition, and availability of food.
• In the existence of chronic malnutrition, the genomic stability and gene expression can be influenced, with genome stability sometimes resulting in mutations of gene sequences and mutations at the levels of chromosomes.
Thus, poor nutrition can result in the change in the expression of trait.

One of the major concerns about seawater desalination is its high expense. Another concern is the disposal of leftover brine from the desalination process back into the ocean, which harms marine life. Discuss whether these two concerns are enough to prohibit the widespread use of desalination as a source of drinking water.
Answer:
Yes.
Explanation:
Yes, these two concerns are enough to prohibit the use of desalination as a source of drinking water because this method is too expensive as well as bad for the marine environment. First, this desalination process is too expensive which is non-economical for the country while on the other hand, it greatly damaged the aquatic animals so this method must be stopped due to its adverse effect on both economics as well as environment.

Bacteria:
They are predominant prokaryotes above 1000 m. A common genus is Pelagibacter. Some types found in the photic zone carry out aerobic photosynthesis.So, the statements (c), (h), and (i) are true about bacteria.
Archaea:
Most of these living below 1000 m are thought to be ammonia oxidizers. Below 1000 m the most common phylum is Thaumarchaeota. They increase to near 50% of total prokaryotes below 1000 m.So, statements (d), (e), and (f) is true about Archaea.
Viruses:
Most are inactivated by hydrolytic enzymes or sunlight. Turnover in seawater is relatively rapid; the populations are replaced within a few days or weeks.They are the most numerous biological entities in seawater.So, statements (a), (b), and (g) are true about Viruses.

. The number and type of prey items found in the owl pellet can be the result of the following factors: availability and abundance of prey, the ease or difficulty of catching the prey, and the taste preference of the owl. Create an experimental design that would describe the diets of barn owls while accounting for these factors.
Explanation:
Experimental design based on the factors mentioned
Check for availability of prey in same habitat as the Barn owl
Determine the type of prey available in the habitat because Owls feed mostly on small rodents like mice, vole e.t.c
If there is an abundance of prey, Check for the most common and easy to catch prey for an owl . considering the taste of the Barn owls while carrying out this experiment .
The Barn Owls feed mostly on Field voles to other kinds of rodents. therefore the availability and ease of catching a Field vole should be prioritized if they are readily available in the same habitat with the Barn Owls. if Field voles are not available the Barn owls can also feed on other rodents and smaller birds available .
Conclude your experiment
The diets of barn owls depend on the availability and abundance of prey, the energy requires to catch the specific prey, and taste preference based on its behavior.
What do you mean by Prey?Prey may be defined as an animal or any other organism that is hunted or killed by another animal for the purpose of food.
Barn owl decides its food on the basis of availability and abundance of prey because in order to survive barn owl checks the presence of a particular prey that are easily available and found in high number. Mostly barn owl prefers small species of rodents like mice, young one of rabbit, and sometimes birds.
Other than this it also depends on how much energy is required to catch the particular prey because if the energy is greater than that of benefit, barn owls eliminate this behavior.
And last barn owls choose those prey that is palatable in nature and have good taste. Bad taste or toxic taste is eliminated in nature.
Therefore, the diets of barn owls depend on the availability and abundance of prey, the energy requires to catch the specific prey, and taste preference based on its behavior.

Answer:
Based on knowledge of enzymes and the given data, it can be concluded that Tcn-protease is most likely active in the alligator's stomach and Wx-protease is most likely active in the alligator's intestines. As clear from the graph, the enzymic activity for Tcn-protease is highest at an acidic pH, which means it works best in an acidic environment, such as the very acidic stomach of an alligator. It is additionally clear from the graph that the enzymic activity for Wx-protease is highest at a neutral pH; therfore, it is most likely to be found in a neutral environment, such as the alligator's intestines.
Explanation:
A pH less than seven is acidicA pH of at or around seven is neutralA pH of more than seven is alkaline (basic)Fernanda is feeling sick and goes to the
doctor. Upon taking a blood sample, the
doctor observes that Fernanda's cells
contain a pathogen that seems to be made
of small cells with no nucleus. What type of
infection does Fernanda have?
bacterial
fungal
none of the above
viral
Answer:
bacterial
Explanation:
A prokaryotic organism is an organism that does not possess a membrane-bound nucleus that houses its genetic material. Organisms grouped under this domain are bacteria, archaebacteia etc.
According to this question, Fernanda goes for a blood sample because she felt sick. The result of the blood sampling shows that the cells of Fernanda contain a pathogen that seems to be made of small cells with no nucleus. This property describes a prokaryotic pathogen. Hence, the infection is most likely to be that of a BACTERIAL INFECTION.
Note that, a fungus is eukaryotic while a virus is considered non-living because it can only replicate in a living host.
