Answer:

This will help you

Explanation:

In more serious cases, stress may cause a decrease in blood flow and oxygen to the stomach, which could lead to cramping, inflammation, or an imbalance of gut bacteria. It can also exacerbate gastrointestinal disorders, including Irritable bowel syndrome (IBS) Inflammatory bowel disease (IBD)

expeople1 [14]

Answer:

Ashing process is done to evaluate the ash content present in petroleum or other proucts, so that they can be used for certain applications

The two major types of ashing process that includes dry ashing and wet ashing and can be performed using microwave systems or conventional means.

a. errors made in the preceding method while determining the ash content of buttermilk by conventional dry ashing are as following:

  • Buttermilk should not immediatly put into muffle immediatley, it should be boiled first to avoid splatter.
  • Temperature should be between 500 to 600 degree celcius at high temperature teh ash content can be loss.
  • The sample should be ashed for 12-18 hrs , more than this can damage the required ash content.
  • platinum tip should be used in place of stainless steel because platinum has a lower concomitant tip impedance than stainless stell, so less reactive to ash.
  • The ash should put in dessicator and not allow to kept in open because ash can react with the humidity in teh atmosphere.

b. The result that occur due to above errors such as the temperature, time,  tongs and leaving ash in open will manipulate the final ash content and its application can be harmful for humans and for other purpose if it will be used.

The plants in this ecosystem are dark in color to absorb sunlight, covered in hair and grow in clumps. What type of ecosystem co
Rufina [12.5K]

Darker colors absorb and retain warmth than warm tones. As a result, plants in the tundra have dark-colored leaves, hairy and clumped and stems to help them absorb solar heat faster and stay warm for longer periods of time. So it could be tundra ecosystem according to the given scenario.

<h3 /><h3>What is tundra ecosystem?</h3>

Tundra ecosystems are treeless areas found in the Arctic and on mountain peaks where the climate is cold and windy and rainfall is scarce.

Much of the year, tundra lands are covered in snow, but summer brings bursts of wildflowers.

Darker colors absorb and retain warmth than warm tones. As a result, plants in the tundra have dark-colored leaves, hairy and clumped and stems to help them absorb solar heat faster and stay warm for longer periods of time.

Thus, the correct ecosystem for the given condition is tundra.

Why was molecular testing necessary to establish that species Z was closely related to Butanol Curus? In other words, why couldn
azamat

Answer:

Because it is only possible to be 100% sure that two species are closely related, in genetic terms, when the DNAs of these species can be analyzed. This analysis is only possible through molecular tests.

Explanation:

Molecular tests are bikini techniques that can analyze species at the molecular level, more specifically, these tests can deeply analyze the DNA (or RNA and proteins) of a species giving precise results on the molecule and allowing scientists to study it deep.

In studies, where the scientist wants to know how the species are genetically related, it is common for molecular tests to be introduced, as a way for the scientist to be 100% sure of the relationship between the species.

How can one species eventually change into something completely different over the course of millions of years?
MrRissso [65]

One species eventually changes into something completely different over the course of millions of years. This can be described using the evolution theory. The evolutionary process of species shows how one population of a species changes over time to the point where that population is distinct and can no longer interbreed with the parent population. Hence one species is changed into another over o period of time. Speciation is an evolutionary process by which a new species comes into being.

This theory of evolution was proposed by Charles Darwin.
