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.

Why are ion channels necessary to transport ions into or out of a cell?
Answers
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.

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.

Answers
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? *
Answers
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.

What happens when self-determination mechanisms break down?
Answers
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.

2. Ribosomes on the RER synthesize proteins.
3. Proteins are packaged into transport vesicles.
4. Modified proteins may be secreted from the cell by exocytosis.
5. Proteins are modified by the Golgi apparatus.
A. 2, 4, 3, 1, 5
B. 3, 2, 1, 4, 5
C. 1, 2, 3, 5, 4
D. 2, 3, 1, 5, 4
Answers
Answer:
D
Explanation:
The correct option here would be D.
The endomembrane system refers to a group of membrane-based organelles whose primary function is to synergistically work together to modify, package, and transport lipids and proteins. The system includes organelles such as the lysosome, the nuclear envelope, the endoplasmic reticulum, and the Golgi apparatus.
For an endomembrane system function involving a protein, the protein would first of all need to be synthesized by the ribosome - the free ones or the ones attached to the rough endoplasmic reticulum. Thereafter, the synthesized protein would then be folded or packaged into transportable vesicles. The vesicles are then received by the Golgi apparatus which further modifies the proteins before transporting them accordingly.
Hence, the correct order of a typical endomembrane system function would be:
Ribosomes on the RER synthesize proteins.Proteins are packaged into transport vesicles.Golgi apparatus receives transport vesicles from the RER.Proteins are modified by the Golgi apparatus.Modified proteins may be secreted from the cell by exocytosis.Protein synthesis involves transcription and translation. Once the protein is synthesized, it suffers a few modifications in the RER and the Golgi complex, before leaving to its final destiny. The correct option is D. ⇒ 2, 3, 1, 5, 4
Protein synthesis and modificationTranscription ⇒ mRNA syntheisThe first step before protein synthesis begins is to synthesize messenger RNA, mRNA.
This is the coping process of the DNA section for the desired protein, and it happens in the nucleus.
Translation: Cytoplasm stageTranslation takes place when the formed mRNA moves to the cytoplasm through the nucleus membrane pores, and meets a ribosome.
Ribosomes are organelles composed by the association of proteins with rRNA and tRNA. They can be found in the rough endoplasmic reticulum or floating in the cytosol.
While the ribosome reads mRNA strain from its 5´ extreme to 3´, tRNA adds the correct amino acids to build the polypeptide.
Endoplasmic Reticulum StageSome proteins are destined for membrane or exportation. Their synthesis starts in the cytoplasm but finishes in the Rough endoplasmic reticulum.
When the ribosome and the growing molecule reach the RER, the synthesizing protein keeps enlarging forward the reticulum lumen.
When the new polypeptide synthesis is complete, it is released into the reticulum lumen.
The endoplasmic reticulum is in charge of protein folding, maturation, and transport, especially those destined for secretion. It produces the latest protein modifications after transduction and initiates the glycosylation process.
The new proteins get packaged into vesicles that carry them to the Golgi complex.
Golgi complex stageOnce the protein synthesis in the endoplasmic reticulum is over, these molecules are packaged into vesicles and sent to the Golgi complex.
In the Golgi complex, proteins suffer their final association with carbohydrates and lipids to originate glycoproteins and glycolipids.
Destiny stageGlycoproteins and glycolipids are packaged again into new vesicles that drive them to their final destiny.
Proteins destined for exportation are packaged and sent from the Golgi complex to the cell membrane into vesicles.
When the secretory vesicle reaches the target, its membrane fuses with the cell membrane, releasing its content to the extracellular space. This secreting process is known as exocytosis.
According to this resume about protein synthesis, we can say that the correct order is option D. ⇒ 2, 3, 1, 5, 4
2. Ribosomes on the RER synthesize proteins.
3. Proteins are packaged into transport vesicles.
1. Golgi apparatus receives transport vesicles from the RER.
5. Proteins are modified by the Golgi apparatus.
4. Modified proteins may be secreted from the cell by exocytosis.
