to prevent acid from seeping in the stomach, the stomach cells join one another via
Answers
The stomach and the cells that comprise it have a three-part protection system to protect from the acid contained in the stomach, comprised mostly of compact cell unions.
The stomach is one of the main digestive tract organs. Its job is to break down the food we ingest and pass it along to the rest of the digestive tract. To perform this action, the stomach secrets hydrochloric acid. However, the stomach itself is not damaged by this acid due to a three-part protective system comprised of:
Tight epithelial cell liningMucose BarrierBicarbonate secretionThe cells present in the epithelial lining of the stomach join one another via compact cell unions to form a closed barrier which is then covered by a thick Mucose barrier. This along with the secretion of bicarbonate which works to break up the acids present in the stomach and ingested, form a sealed barrier that protects the stomach from harm.

Answer: (B) The two species have high molecular homology
Explanation: Molecular homology means resemblances between species on the molecular level. Since the two species from the answer in Part A have the smallest difference in Cytochrome C it means they have high molecular similarities; this is due to evolving from the same common ancestor.
(A) is not the right answer because the fungi in the table might all look similar but have different or similar genetic blueprints.(C) is not the right answer because fungi can reproduce sexually or asexually, so reproduction cannot help with determining relatedness.(D) is not the right answer because if the two species from the answer in Part A are closely related because they are both fungi, the answer for Part A should be all of the options.Name the four lapse rates and describe what each affects.

So is it true that the sun will eventually crash into the earth if so that’s just scary
Answers
Answer:
Yes.
Explanation:
All stars have a life cycle, meaning they eventually burn out and die. Currently, the Sun is in its "main sequence" phase, meaning it's fusing hydrogen into helium in its core. Then, it'll eventually be in the "Red Giant" phase. During this phase, the Sun has begun thermonuclear fusion of hydrogen in a shell enveloping the core. Then, it'll multiply its radii multiple times, and the Sun will eventually engulf the Earth.

If you allowed your dilution tubes to incubate for 24 hours before plating them, do you think the results of the experiment would be impacted
Answers
Yes, allowing the dilution tubes to incubate for 24 hours before plating them can impact the results of the experiment. The incubation period allows for bacterial growth, and the longer the incubation period, the more time bacteria have to multiply and potentially change in number and/or characteristics.
If the incubation period is too long, the bacteria may overgrow or die off, leading to inaccurate results. Alternatively, if the incubation period is too short, the bacterial colonies may not have enough time to grow to a size that can be counted accurately.
Therefore, it is important to follow the recommended incubation period for the specific type of bacteria being studied, as this can help to ensure accurate and reliable results.

Answers
Answer:
The area between 200 and 1,000 meters (656 and 3,280 feet) is the mesopelagic or “twilight” zone.
Explanation:
Light intensity in this zone is severely reduced with increasing depth, so light penetration is minimal. About 20 percent of primary production from the surface falls down to the mesopelagic zone.

A molecule that closely resembles the shape of a substrate for an enzyme and that decreases the activity of the enzyme would most likely serve as a(n):________
Answers
A molecule that closely resembles the shape of a substrate for an enzyme and decreases the activity of the enzyme would most likely serve as a competitive inhibitor.
Competitive inhibitors are molecules that closely resemble the shape of a substrate and can bind to the active site of an enzyme. By occupying the active site, they prevent the substrate from binding and carrying out the enzymatic reaction. This leads to a decrease in enzyme activity.
The competitive inhibitor competes with the substrate for binding to the active site, hence the name "competitive." The inhibitor's structural similarity to the substrate allows it to bind to the active site, but it lacks the necessary functional groups for the enzymatic reaction to occur. As a result, the enzyme-substrate complex cannot form, and the reaction is hindered.
Non-competitive inhibitors bind to a different site on the enzyme, not the active site, and their binding does not depend on the presence of the substrate. They can still decrease enzyme activity, but their mechanism differs from that of competitive inhibitors.

How do root hair cells obtain a supply of sugars?
Answers
Answer:
Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption.
Explanation:
Root hair cells absorb water and minerals from the soil and get a supply of glucose from the phloem.
Phloem:
It is a vascular tissue that transports the nutrients such as sugar throughout the plant.
The sugar is produced in the leaf by the process of photosynthesis. This sugar is transferred to the phloem tissue. Then sugar is transported to the other part of plants such as stem and root.
Therefore, hair root cells get a constant supply of sugar from the leaves via the phloem.

A hiatal hernia is a protrusion of a portion of the _____ through the ______. Group of answer choices stomach; diaphragm duodenum; pyloric sphincter small intestine; inguinal canal rectum; anus
Answers
A hiatal hernia is a protrusion of a portion of the stomach through the diaphragm.
Hiatal hernia is a condition which arises due to a rise in blood pressure. In this condition the stomach bulges up through an opening in the diaphragm. This condition interjects with the normal mechanism of reflux that occurs through the sphincter, which is present in the esophagus. This condition usually occurs when there is excessive pressure around the stomach due to activities like repeated vomiting. This condition is usually not fatal, however, in rare and serious cases this condition can effect the esophagus and cause esophageal cancer. This condition can also lead to leakage of stomach acids and cause ulcers in the alimentary canal. In serious cases of hiatal hernia the blood flow to and from the intestine can also be effected. Serious cases need surgical treatment.

Pando aspen grove in Utah is an immense, genetically identical organism consisting of interconnected aspen trees spanning 100 acres and estimated to be around 80,000 years old.
One of the largest and oldest organisms on Earth, known as Pando, is located in Fish Lake National Forest in Utah. Pando aspen grove is an 80,000-year-old grove of aspen trees that covers approximately 100 acres. While it appears to be a forest, DNA analysis of several of the trees has revealed that they are genetically identical, confirming that Pando is actually one immense organism. The trees of Pando have been reproduced through a process called vegetative reproduction, where new shoots and stems emerge from the existing root system. This unique reproductive strategy has allowed Pando to persist and expand over thousands of years, making it a remarkable example of the interconnectedness and longevity of living organisms.For more questions on Pando aspen grove:
