Answer:
greater than
Explanation:
The pH of limestone in a water solution would be greater than 7.
pH is a measure of the degree of acidity or alkalinity of a solution. If we say that we want to make the ground soil less acidic, then we definitely have to add a basic substance.
A basic substance is one whose pH is greater than 7. The pH scale is organized in such a way that acids span from 0 - 6.9. A pH of 7 indicates neutral while a pH of 8 - 14 indicates a basic substance.
If limestone is basic, it must have a pH greater than 7.

O plant; pure water
O animal; pure water
O plant; 3X salt solution
Answer:
Plasmolysis occurs when a plant cell is inmersed in a 3X salt solution.
Explanation:
Plasmolysis is a phenomenon only observed in plant cells, and consists of cell dehydration accompanied by separation of the membrane and cell wall when the cell is exposed in a hypertonic environment.
When a plant cell is in a hypertonic solution —such as 3X salt solution— the permeability of its membrane allows water to escape, so the cell dehydrates and reduces its size. The cell wall is rigid and maintains its shape, but the cell membrane separates from it, which is known as plamolysis.
The other alternative answer combinations are not correct because:

Gregory Mendel work was different from that of other researchers working in inheritances in his day because he alone
Answer:
Most scientists believed that heredity material blended together in offspring, however, Mendel did not. he believed that an organism inherits one gene from each parent and that some alleles are dominant over others. This would mean that they would show up in the phenotype of an organism.
Explanation:
Hope this helps :)
Answer: Gregory wrote a research paper for his English class. His first step was to choose a topic Then he found some background information about his topic. Next, he began looking for relevant sources. He then evaluated them to check their reliability.
Gregory began to write his paper. He used evidence from his research to back up his arguments. Finally, he cited the sources he used.

this mannitol salt plate was inoculated with an unknown staphylococcus species. what can you conclude about this unknown organisms
Complete question: Analyzing Mannitol Salt Agar (MSA): An MSA plate was inoculated with an unknown Staphylococcus species. What can you conclude about this unknown organism?
A. It can ferment mannitol.
B. It produces acid during fermentation, leading to a lower pH in the medium.
C. It can tolerate higher salt concentrations.
D. It could be S. aureus.
E. All the above
Answer: The correct option is E ( all of the above)
Explanation:
Culture medium is a growth medium that is used in microbiology which permits the growth of microorganisms. It can be in a gel or liquid form. There are different types of culture medium which includes:
--> Differential medium
--> Selective medium
--> Enriched medium
Mannitol Salt Agar( MSA) is a type of selective culture media that is used in microbiology for the identification and isolation of staphylococcus species from biological samples. A typical MSA includes essential growth factors and trace nutrients such as nitrogen, vitamins, minerals and amino acids essential for growth. The medium contains sodium chloride( salt) with mannitol which is the fermentable carbohydrate source
Staphylococcus aureus organisms are capable of fermenting mannitol, produces acid during fermentation leading to a lower pH in the medium, and can tolerate higher salt concentrations. Therefore the unknown organism is POSITIVE to mannitol salt agar analysis. Thanks and I hope it helps!

In passive transport, molecules move__ the concentration gradient.
Answer:
In passive transport, molecules move with the concentraction gradient.
Explanation:
If molecules moved against it would be active transport.
Passive transportation has been defined as the mode of molecule movement across the semi-permeable membrane. "In passive transport, molecules move down the concentration gradient."
What is passive transport?Passive transport has been the mode of movement of the ions and molecules from the exterior and interior of the cell through the plasma membrane. This mode of transportation has been characterized by the movement of the ions from the region of a higher electrochemical gradient.
The ions tend to move towards the region that lacks the electrochemical gradient, hence it is a movement in the direction of the lower concentration. The solute particles do not external source of energy to drive the movement from higher concentration areas.
It is a type of diffusion that uses the law of Thermodynamics to move the ions up and down the cell concentration. The movement of the oxygen gas in the body cells is an example of passive transportation.
Therefore, the ions move down the concentration gradient in the passive transport.

what change in a population would you expect to see if a selection pressure was against the traits of the dominant allele?
The change in population in the given condition would be an increase of true recessive traits in the population and there would be only a few individuals with dominant traits.
In case of selection pressure was against the dominant trait, then individuals of the population who have true recessive alleles would have an advantage over the heterozygous and dominant individuals of the population.
There would be very few individuals carrying its dominant genotype and it may eventually be extinct, however, it would be still dominant. The recessive trait would just become more prominent rather than becoming dominant.
Thus, the number of recessive traits would increase in population, and the number of dominant decrease to numbers.

https://brainly.com/question/18592700
Decrease occur in the population of dominant allele occurs.
Change in a population of dominant allele occurs if a selection pressure was against the traits of the dominant allele because the selection pressure is against the dominant allele that leads to appearance of recessive allele and disappearance of dominant allele. The selection pressure is responsible for the appearance of allele in the offspring so we can conclude that dominant allele is decreases in the population of the future generation.
