Differentiate between acids and bases on the basis of their pH values. Give an example of each... essay question keep it simple plzzzz need answer ASAP
Answer:
Acids have a pH value of less than 7, the closer it is to one, the more acidic they are
e.g. HCL (hydrochloric acid) found in the stomach which has a pH of between 1.5 and 3.5
Alkaline solutions have pH values of over 7 (neither acids nor alkalis have a pH of 7 as it's neutral) and the closer it is to 14, the more alkaline they are
e.g. sodium hydroxide which has a pH of 14

At which point is the population experiencing carrying capacity?
1
in
Number of fruit flies -
Time
It is reaching carrying capacity at point c because that is where their population starts to plateau on the graph which tells me that their environment cannot hold more any more of them.
The carrying capacity of the fruit fly population is depicted by C. Option c is correct as it shows the carrying capacity. The carrying capacity is the range within which the maximum individual can fit in an ecosystem.
What is carrying capacity?
Carrying capacity means the ecosystem has the capacity to carry that specific number of individuals, and after this range, the population can't survive in that ecosystem. When the population exceeds the carrying capacity, competition for space and food begins, resulting in the death of some members of the species.
The A in the graph depicts the fruit fly population at its initial level. B depicts that the fruitflies are growing rapidly as there is an ample amount of resources. By the time they reach the C, the growth has slowed. After this range, the ecosystem can't provide resources for this population to grow in number.
Hence, The carrying capacity of the fruit fly population is depicted by C.

Recent biochemical evidence divides all organisms into three domains: Bacteria, Archaea, and Eukarya. Previously, Bacteria and Archaea were viewed as one group. Which statement best describes why Bacteria and Archaea have been placed into separate domains?.
Bacteria and Archaea have been placed separately because their cells have differential compositions. Bacteria and Archaea are prokaryotes.
Archaea and Bacteria domainsArchaea and Bacteria domains are prokaryotes because their cells do not contain membrane-bound organelles or cell nuclei.
However, there are certain phenotypic, structural, and evolutionary features to distinguish Archaea and Bacteria domains.
For example, the Archaea cell membrane contains isoprene hydrophobic groups and phospholipid linkages (it is not found in bacteria).

explain genetic drift using the bottleneck effect and founder effect
[tex]\huge{\underline{\underline{\boxed{\sf{ \orange{ αηѕωєя : }}}}}}[/tex]
Genetic drift can cause big losses of genetic variation for small populations.Population bottlenecks occur when a population’s size is reduced for at least one generation.Because genetic drift acts more quickly to reduce genetic variation in small populations, undergoing a bottleneck can reduce a population’s genetic variation by a lot, even if the bottleneck doesn’t last for very many generations. This is illustrated by the bags of marbles shown below, where, in generation 2, an unusually small draw creates a bottleneck.Hope Helps~Find the acceleration due to gravity on Mars if a person with a mass of 60.0 kg weighs 222 N. on Mars.

These variations are most likely the result of polygenic effects. Polygenic traits are controlled by many genes.
Polygenes and inheritanceThe phenotype is any observable feature of an organism, which depends on genotype and environment.
The inherited genes largely determine different phenotypic features (e.g., eye color, weight, etc).
Traits controlled by a single gene are called monogenic, whereas traits controlled by two or more genes are known as polygenic.

What structure holds the two sister chromatids together as they prepare for cell division.
Two sister chromatids are held together by the centromere
The ChromosomeThe chromosome consists of 2 sister chromatids that are linked together by a structure known as the centromere.
Each of the sister chromatids carries an allele of the same gene.
The link between the two sister chromatids is broken at the anaphase stage of the cell division when spindle fibers pull them apart towards opposite poles within the cell.
