Explanation:
The lactose (lac) operon in e. Coli is an example of a gene that is expressed when lactose is not available in a cell.
The given statement is false that the lactose (lac) operon in E. coli is an example of a gene that is expressed when lactose is not available in a cell.
Lactose operon is the set of genes present in the prokaryotic cells that work together in order to conduct the metabolism of lactose. The genes of the operon are expressed when lactose is present and glycose is absent in the cell.
Gene is the most basic and fundamental unit of heredity. it is the factor that contains the information for a particular trait. It is present on the chromosome at a certain specific location. There are several genes present in the living organism's genetic material that code for various traits.

Axolotls live in a very specific place in Mexico and are on the endangered species list due to pollution, overfishing, and habitat loss. What
would happen to their population if we were not able to change one of the three threats?
The planet will someday become congested due to the tremendous rate of population growth. Global warming with increased population density.
What will occur in the event of an overpopulation?The need for food, water, houses, energy, healthcare, transportation, and other resources will rise as the population grows. All of this consumption increases the likelihood of major catastrophes like pandemics, increases conflicts, and degrades the environment.
If a population doesn't have adequate resources, what will happen?When resources are scarce, "competition" intensifies and some organism populations decline. Without access to the materials they require, some people might even become smaller or weaker. The availability of resources may be impacted by environmental changes, natural disasters, and people.

Answer: DNA has two strands and each is made up of a phosphate-sugar backbone
Explanation:
DNA is double stranded. The backbone of each strand consists of phosphate groups bound to ribose sugars.
Adenine pairs with Thymine A - T
Cytosine pairs with Guanine G - C
The nucleotides in DNA are held together by hydrogen bonds not covalent.
what environmental problem is being addressed by the use of bio swales, large vegetated ditches or depressions, on the campus of georgia southern university?
The environmental problem is being addressed by the use of bioswales, large vegetated ditches or depressions is the pollution of streams by oily runoff water from parking lots.
Due to the advantages that bioswales provide for communities and other settings, they are a landscape component that are receiving more and more attention recently. The "bio" in "bioswale" refers to the usage of what is referred to as a swaled drainage course, which is created with sloped sides and often filled with plants, compost, and other biological elements.
Together, these drainage components produce a setting where water will spend a considerable length of time, removing contaminants and silt. A town or area can profit from the self-sustaining draining and pollution removal mechanism created by the water for years to come. The water also helps to keep any vegetation or compost fresh.

Explain how salinity and temperature affect water density in the ocean
Answer:
As the temperature of water increases, it expands and becomes less dense. This means that warm water is less dense than cold water. On the other hand, as the salinity of water increases, the concentration of dissolved salts in the water increases. This makes the water more dense. So, if the temperature and salinity of the water are the same, the water will have the same density. However, if the temperature or salinity of the water changes, the density of the water will also change.
there are a large number of antibiotics that inhibit protein synthesis at 70s ribosomes found in bacterial cells but do not interfere with protein synthesis at the 80s ribosomes found in eukaryotic cells. some of these antibiotics bind to the smaller ribosomal subunit and interfere with the reading of the mrna code, whereas others bind to the large ribosomal subunit and inhibit the formation of peptide bonds. unfortunately, some of the antibiotics that inhibit protein synthesis in bacteria exhibit some toxicity to the eukaryotic host cells as well. what is the most likely reason for this toxicity to the host cell?
The most likely reason for the toxicity of certain antibiotics to the eukaryotic host cells is due to the fact that these antibiotics are not completely selective in their inhibition of protein synthesis.
These antibiotics may be effective in inhibiting protein synthesis at the 70's ribosomes found in bacterial cells, but may also tend to inhibit protein synthesis at the 80's ribosomes found in eukaryotic cells. not. This is because the 80's ribosomes found in eukaryotic cells are structurally so similar to the 70's ribosomes found in bacterial cells that antibiotics may not be able to distinguish the two. is. As a result, the antibiotic is able to bind to both 70's and 80's ribosomes, thereby inhibiting protein synthesis in both bacterial and eukaryotic cells.
This inhibition of protein synthesis in eukaryotic cells can result in toxicity to the host cell as the production of proteins required for normal cell function is inhibited. This can disrupt normal cellular processes, resulting in cell death and other adverse effects. To reduce the toxicity of a particular antibiotic to eukaryotic host cells, it is important to ensure that the antibiotic is selective in inhibiting protein synthesis.
This is accomplished either by designing antibiotics to target specific regions of the ribosome or by introducing chemical modifications into antibiotics that block their ability to interact with the 80's ribosomes found in eukaryotic cells. I can do it. By ensuring that the antibiotic only interacts with the 70's ribosomes found in bacterial cells, potential toxicity to host cells can be minimized.

Anatomy of the eye showing the outside and inside of the eye, including the eyelid, pupil, sclera, iris, cornea, lens, ciliary body, retina, choroid, vitreous humor, and optic nerve. Important functions of the cornea of the eye include protecting the structures inside the eye, contributing to the refractive power of the eye, and focusing light rays onto the retina with minimal scattering and optical degradation. This is a transparent tissue that protects the inside of the eye and focuses light towards the lens and retina of the eye.

A student is going to be diving to collect shells. The instructor tells him to exhale as much as possible and then take a breath of air before he dives.
How would this help the student stay underwater for a longer period of time?
Answer: It decreases CO2
Explanation:
Answer:
Practice deep breathing. Before holding your breath, inhale and exhale slowly from deep within your diaphragm. By doing this, you're ridding your lungs of low-quality air.[1] Spend five seconds breathing in, then hold the breath for one second, before breathing out for ten seconds. Continue deep breathing for two minutes, and be sure that when you exhale, you push out every last "drop" of air.
Explanation:
The hyperventilation reduces the body's carbon dioxide content but does not affect oxygen content much, but the Fio2 of 100 kPa considerably increases the total oxygen content. Hyperventilation before diving enables breath hold divers to stay down longer but is very dangerous.

The Neanderthals were a tolerant of the cold. Similar to their face characteristics, Neanderthals' bodily proportions varied. They did, however, have large chests and relatively small lower limb extremities compared to their upper arms and legs. They must have had enormous, well-muscled arms and legs.
How did Neanderthals most likely adapt to their environment?Neanderthal populations were versatile, living in warm temperate forests approximately 120,000 years ago in Spain and Italy and in chilly steppe settings in England and Siberia about 60,000 years ago.
They could have been able to warm up and inhale more air because to their big nasal aperture. Their small limbs probably assisted them in retaining body heat. Since the last common ancestor of humans and neanderthals, skeletal variations are the consequence of adaptations.
