Answer:
substitution; deletion; insertion
Explanation:
Mutations are genetic changes generally associated with deleterious effects. However, mutations may not have an effect on the phenotype of the organism and even, eventually, they are beneficial. For example, a missense substitution occurs when a nucleotide is replaced by another that changes the encoded amino acid, which may have deleterious or beneficial effects (depending on the new protein and its effects on the fitness of the individual in a particular environment), while a silent substitution does not modify the encoded amino acid and thereby it has no effect on the phenotype. On the other hand, a frameshift mutation is a mutation that involves the insertion or deletion of a nucleotide base, thereby irreversibly altering the Open Reading Frame (ORF) of the protein.

4. If a mutation blocked the function of the signal recognition particle, making it unable to bind signal sequence, what would result
Answer:
All proteins would be translated in the cytoplasm
Explanation:
The signal recognition particle (SRP) is a cytoplasmic RNA-protein (ribonucleoprotein) complex whose primary role is to target signal peptide‐bearing proteins to the plasma membrane in prokaryotes and to the endoplasmic reticulum in eukaryotes. In eukaryotic organisms, SRP binds to the signal sequence of the protein when the growing polypeptide chain emerges from the ribosome in the cytoplasm. This binding is key because it results in a slowing of translation, a mechanism known as elongation arrest. Therefore, without a functional SRP, elongation arrest would not occur and proteins would be translated on free ribosomes in the cytoplasm.
c. What is the approximate carrying capacity for each population, as indicated by the graph?
(1 point)
Answer:
The carrying capacity of Area A looks like 30 and B looks like 15
Explanation:
Carrying capacity is the amount of things that can be supported using all of the resources available. This is just an estimate btw
what are the effects of mutations
Explanation:
When a mutation alters a protein that plays a critical role in the body, it can disrupt normal development or cause a medical condition. A condition caused by mutations in one or more genes is called a genetic disorder. In some cases, gene mutations are so severe that they prevent an embryo from surviving until birth.

is it currently possible to take a core sample?
Answer is YES your welcome
Explanation:
Core samples are most often taken with their long axis oriented roughly parallel to the axis of a borehole, or parallel to the gravity field for the gravity-driven tools. However it is also possible to take core samples from the wall of an existing borehole.
anyone know the answer???
Answer:
The first one
Explanation:
Quantitative data is data in the form of numbers
Answer: The first option
Explanation: Quantitative data means data that is able to be measured or counted. The first option has 740, which can be counted. The second option is wrong because saying a lake is large is an opinion, meaning it isn't measured. The third option is also an opinion. The last option is also wrong since characteristics such as features or the appearance of something is not quantitative, instead they are qualitative features.
Quantitative data requires something to be measure or counted
Qualitative data requires observations, such as color or appearance

theory that states all living things are made of cells, that they are the basic unit of structure and
function, and new cells are produced from exisiting cells
Answer:
unified cell theory
Explanation:
The unified cell theory states that: all living things are composed of one or more cells; the cell is the basic unit of life; and new cells arise from existing cells. Rudolf Virchow later made important contributions to this theory.

According to the host, which of these is true of the reaction between ammonia and hydrochloric acid?
A.
It is considered an acid-base reaction because there is proton donation and acceptance.
B.
It is not considered an acid-base reaction because there is no hydroxide present in the base.
C.
It is not considered an acid-base reaction even though there is proton donation and acceptance.
Answer:
A.
Explanation:
In water, the reaction between ammonia (NH3) and Hydrochloric Acid (HCl) is an example of acid-base chemistry. By its chemical nature, the nitrogen in ammonia prefers to be attached to four hydrogens rather than the three it has, so it receives them from the hydrogen from HCl

What is the percentage of agar required to prepared a solid medium?
Answer:
1-2%
Agar is typically used in a final concentration of 1-2% for solidifying culture media. Smaller quantities (0.05-0.5%) are used in media for motility studies (0.5% w/v) and for growth of anaerobes (0.1%) and microaerophiles.
why is fertilizer essential
Answer:
Fertilizer is essential in agricultural practice because it adds the needed nutrients to the soil.
Explanation:
Given that each successful cultivation of crops leads to the removal of nutrients in the soil. To retain the level of nutrients in the soil so the plants can germinate extremely well. There is a need to add fertilizers to the soil.
Therefore, fertilizers are essential because "it adds the needed nutrients to the soil." Thereby retaining and improving the harvest level of plant crops.
