A population of frogs in a pond began with 67 individuals. Over one year, the population changed to 53.
Which are two possible reasons for the change within the frog population?
emigration or increase in death rate
emigration or increase in birth rate
immigration or decrease in death rate
immigration or increase in birth rate
PLZ HURRYYYY 20 POINTS
Answer:
A. emigration or increase in death rate
Explanation:
i just took the test and got it rigt lol
The two possible reasons for the change within frog population is emigration or increase in the death rate. Thus, the correct option is A.
What factors affect the population?The major factors which affect the population of a species are birth rate, death rate, and migration of the species.
Birth rate is the number of individuals born in a population in a particular time period. Birth rate adds more individuals to a population.
Death rate is the number of individuals die in a population in a particular time period. Death rate decreases the population number.
Immigration is the number of individuals which enter a population.
Emigration is the number of individuals which migrate out of a population.
Therefore, the correct option is A.

isolation occurs when two species occupy different habitats within the same geographical range.
Question:
_____ isolation occurs when two species occupy different habitats within the same geographical range.
Answer:
Habitat
Explanation:
Habitat isolation occurs when individuals in two populations are separated geographically. For example by a river or a mountain range. These organisms are much less likely to interact with each other and attempt to reproduce.
Habitat isolation is a barrier to gene flow (mixing of genes in two populations) and is a mechanism of speciation.

Carrie is conducting an experiment on a solution. The solution’s initial pH is 10. Then, as Carrie gradually adds Compound X into the solution, the pH decreases to 5. Which is the most likely identity of Compound X? *
Answer:
Compound X must be an acid
Explanation:
Acids have a lower pH than alkaline solutions. When you add an acid to a solution, the pH drops, as has happened here. If the pH did not change, we would assume compound X was neutral. If the pH increased, we would assume compound X was even more alkaline than pH 10.
Why are ion channels necessary to transport ions into or out of a cell?
Answer:
Ions carry electric charges and are not soluble in the lipid bilayer of the cell membrane.
Explanation:
I found it on google lol
Ions are too large molecules to diffuse through the cell membrane hence require some proteins to facilitate their transport. Ions channels helps in transporting the ions through the cell membrane and the flow of current through the membrane.
What are ion channels?
Ion channels are the type of transport proteins which are present in the cell membrane that facilitates the movement of ions through the membrane. Cell membrane is selectively permeable in nature and thus does not allow many molecules to transport through it.
Ion channels facilitates the passive movement of ions across the cell membrane and are essential for cell survival. Ion-channels helps in elucidating the structure-function mechanisms of the proteins present in the membrane. Ion channels help in creating ion gradient and moving charge through the membrane.

O deer drinking from a stream
O a robin hatching from an egg
O minerals forming under Earth's surface
Answer:
minerals forming underneath the earth's surface
Explanation: this is correct because I researched about it
The examples of connections between Earth systems are as follows:
Ice melting on a lake. Deer drinking from a stream.A robin hatching from an egg.Minerals form under Earth's surface.Thus, all the above options are correct.
What is the Earth system?The Earth system may be defined as all those processes that deal with physical, chemical, and biological interactions.
This system also consists of the land, oceans, atmosphere, and poles and includes the planet's natural cycles such as carbon, water, nitrogen, phosphorus, sulfur, and other cycles, and deep Earth processes.
The melting of ice on a lake is the physical transformation on the earth's surface. Deer drinking from a stream is the interaction of a living being with an abiotic factor.
A robin hatching from an egg is a biological process. While minerals forming under Earth's surface is a deep earth process.

What happens when self-determination mechanisms break down?
Answer:
When self-determination mechanisms break down it mistakes self-tissue as foreign agents and pathogens. This results is Auto-Immune disease.
HOPE THIS HELPS!
When the self-determination mechanisms break down, the body misinterprets its own tissues as foreign antigens, which activates the autoimmune mechanisms to destroy the body's own cells, mistaking them for foreign factors, this happens mainly in mantle autoimmune diseases.
Autoimmune diseases are a group of diseases in which tissue damage is caused by a humoral or cell-mediated immune response to a person's own antigens.
What are antigens ?In immunology, an antigen (Ag) is a molecule or molecular structure or any foreign particle or pollen grain that can bind to a specific antibody or T-cell receptor. The presence of antigens in the body can trigger an immune response. The term antigen originally referred to a substance that is a generator of antibodies. Antigens can be proteins, peptides (chains of amino acids), polysaccharides (chains of monosaccharides/simple sugars), lipids or nucleic acids. Antigens are recognized by antigen receptors, including antibodies and T-cell receptors.

Describe the differences and similarities between mitosis and binary fission.
Answer:
Binary fission is a method of asexual reproduction which single-celled organisms, usually prokaryotes, use to create a copy of themselves. Another term for the process is cellular cloning. Mitosis is cell division that results in two identical daughter cells and is primarily used for growth of an organism.
Explanation:
Binary fission has been known as method of asexual reproduction which single-celled organisms, usually prokaryotes, use to create a copy of themselves. Another term for the process is cellular cloning.
What is mitosis?Mitosis is cell division that results in two identical daughter cells and is primarily used for growth of an organism.Chromosomes are generally seen below a mild microscope best for the duration of the metaphase of molecular division.
The chromosomes are separated by a structure called the mitotic spindle. A chromosome is a lengthy DNA molecule with component or all of the genetic material of an organism. In maximum chromosomes the very lengthy skinny DNA fibers are lined with packaging proteins; in eukaryotic cells the maximum vital of those proteins are the histones.
These proteins, aided by chaperone proteins, bind to and condense the DNA molecule to keep its integrity. These chromosomes show a complicated third-dimensional structure, which performs a large position in transcriptional regulation. Chromosomes are generally seen below a mild microscope best for the duration of the metaphase of molecular division.
Therefore, Binary fission has been known as method of asexual reproduction which single-celled organisms, usually prokaryotes, use to create a copy of themselves. Another term for the process is cellular cloning.
