Cells produce different molecules that can function at the new pH levels.
Most biological molecules can function at any pH value.
Most biological molecules can function at any pH value.
They have substances that counteract acids or bases to prevent the pH from changing.
Answer:
The correct answer is - They have substances that counteract acids or bases to prevent the pH from changing.
Explanation:
Including human, all the organism depends on the water so therefore known as waster system based which suggests that they depend on the acid-base liquid equilibrium to maintain its cellular functions and homeostasis.
Acid and bases are influences and determine the pH value of the chemistry of biological systems as every cycle is affected by the pH fluctuation so the maintenance of pH is very critical.
so as to keep biological system compound and in the equilibria of protonation, they have certain substances in each cycle or part that counteract the acid and base to maintain pH.
for instance:
phosphate ion maintains the Cytoplasm pH
the bicarbonate ion regulates the Blood pH

D.Transmission microscopes produce images of living cells.
Answer:
C
Explanation:
:)
The statement that best describes transmission electron microscopes is:
C.Transmission microscopes produce highly detailed images of cell structuresA microscope is the instrument that is used to view microorganism and magnify them so that they cab be visible to the human eyes.
The transmission electron microscopes are those micrpsccp[es wjich makes use of a particle beam in order to produce a well magnified image and can magnify an object uo to two million times.
As a result of this, they produce highly detailed images of cell structures.

Actually Welcome to the Concept of the Thermodynamics,
From the above Table 1 , we can actually conclude that,
Substance A and Substance B temperature rates are totally different and has no relation between them, also they are increasing with the time.
hence the, correct options are,
1.) and 4.)
1.) There is no relationship between heating time and temperature for either substance .
4.) as time increased, the temperature increased for the both substances.

Explain what would happen to the food chains if:
a.) A toxin was released into the local water supply, and the mice in the meadow died.
b.) There was an increase in the hawk population.
a. The hawks would die because the mice died, since the bottom part of the food chain was taken out, the whole food chain would fall apart;
b. All the mice would die; since there are more hawks to eat the mice, the mice would be eaten faster than they could reproduce, and they would slowly die out.

Which part of the microscope is used to make small adjustments in the image of an object?
A)Eyepiece
B)Fine Adjustment
C)Coarse Adjustment
D)Objective lens
Answer:
The part of the microscope that is used to make small adjustments in the image of an object is the fine adjustment.
Explanation:
In the optical microscope, the fine adjustment knob allows precise focusing of the sample being studied. This means making minimal adjustments in order to better observe the microscopic image.
After the initial focusing with the coarse adjustment knob, with the fine adjustment it is possible to highlight the details that require more attention, as well as the refringency of the sample, if it exists.
The other options are not correct because:
A. Eyepiece is the lens that receives the image from the objective lens, that has contact with the eyes of the observer.
C. Coarse Adjustment is the rough magnification, used for the initial approximation of the image.
D. Objective lens enlarges and defines the image of the sample on the slide.

What impacts would suburban development have on undeveloped deciduous forest and meadow ecosystems?
Answer:
Impacts of suburban development on undeveloped deciduous forest and meadow ecosystems are - : loss of biodiversity , excessive land use , deforestation , degradation of air quality , increase in the amount of greenhouse gases , therefore leading to environmental loss .
Explanation:
SUBURBANIZATION -: Suburbanization is a demographic change, resulting in the creation of (sub)urban sprawl, from core urban areas to suburbs. Low-density, peripheral urban areas are increasing as a consequence of the migration of households and companies out of the city centers. (Urbanization, which signifies a demographic change from rural areas to urban centres, is inversely related to suburbanization.)
Within the central urban area, many residents of metropolitan regions work and prefer to live in satellite communities called suburbs and commute to work by car or mass transit. Others have taken advantage of advances in technology to operate from their homes.
Environmental Implications -: This can have negative effects on the community with the growth of suburbanization and the spread of individuals living outside the city. Suburbanization has been related to an increase in the mileage of automobiles, an increase in land usage, and an increase in the use of residential electricity. These suburbanization factors then induced air quality deterioration, increased use of natural resources such as water and oil, and increased quantities of greenhouse gases. This causes increased use of oil and gas as well as an increase in pollution as the use of cars to drive to and from the workplace grows. This will then cause air pollution and degrade the air quality of a region with a rise in emissions from vehicles. Suburbanization is increasing, leading to an increase in housing growth, which causes the consumption of land and land available to increase.
