Answer:
The correct answer is "nucleus cytosol; mitochondrion or chloroplast".
Explanation:
A transit sequence, also known as signal peptide, in a protein is a series of amino acids that indicate that a protein is not synthesized matured, and a portion of the protein must be cleaved in order to have the protein in its mature form. Transit sequences serves as regulators of protein transport, since they indicate that a protein must transit from the nucleus cytosol to different organelles, such as the mitochondrion or chloroplast. Examples of this type of proteins, include: alcohol dehydrogenase, DNA polymerase, and RNA polymerase.

5. Translocations Deletions Occurs when the same piece is repeated within a chromosome 5
6. Examples include Wiliams syndrome and Cri du chat syndrome
7. Occurs when pieces of a chromosome are lost
A. Duplications
B. Inversions
C. Translocations
D. Deletions
Answer:
1. It depends on the DNA region that has been affected by the chromosome rearrangement
2.Translocations
3.Translocations
4. Inversions
5. Duplications
6. Deletions
Explanation:
A translocation is a chromosome rearrangement where a chromosome fragment breaks off and the resulting portion attaches to another genome region. An inversion occurs when a single chromosome fragment is reversed end to end, thereby also producing a chromosome rearrangement. Inversions can be classified into pericentric (include the centromere) and paracentric (not include the centromere). Finally, chromosome duplications and chromosome deletions are opposite rearrangements where chromosome portions are copied in tandem and eliminated, respectively.

State the unique characteristics of epithelial tissue.
Answer:
Characteristics of epithelium tissue
1.Polarity- Epithelium is arranged so there is one free surface (apical surface) and one attached surface (basal surface)
2.Cellular nature– Cells in epithelium fit closely together side by side and sometimes atop each other to form sheets of cells. These sheets are held together by specialized junctions.
3.Supported by connective tissue– Attachment to a layer of connective tissue at the basal surface forms a layer called the basement membrane, an adhesive layer formed by secretions from the epithelial cells and the connective tissue cells.
4.Avascular– Epithelium typically lacks its own blood supply.
5.Regeneration– Epithelium cells can regenerate if proper nourished.
6.Absence of nerves (except for a few axons in the deeper layers)
Classification scheme of epithelial tissue:
Typically epithelial tissue is classified on the basis of arrangement and shape of cells. For naming the tissue types, the arrangement of the cells is stated first, then the shape, and is followed by “epithelium” to complete the naming. For example; Simple Squamous Epithelium.

Calculate the volume of 1 M NaOH needed to prepare 12.0 mL of a 0.10-M solution. Prepare this solution. (Refer to the Dilutions section in the Background.)
Answer:
1.2 mL
Explanation:
This is a problem of simple dilution. The dilution principle simply agrees that the number of moles before dilution must be equal to the number of moles after dilution.
Recall that: number of moles = mass/molar mass or molarity x volume.
Hence, for the dilution principle:
initial molarity x initial volume = final molarity x final volume.
In this case, initial molarity of NaOH = 1 M, initial volume = ?, final molarity = 0.1 M, final volume = 12.0 mL.
Initial volume = final molarity x final volume/initial molarity
= 0.1 x 12/1 = 1.2 mL
It thus means that 1.2 mL of 1 M NaOH would be taken and then diluted up to 12.0 mL mark by the addition of distilled water in order to produce 12.0 mL, 0.10 M NaOH solution.
The volume should be 1.2 mL
What is the dilution principle?It should be agreed that the no of moles prior to the dilution should be equivalent to the no of moles after dilution
We know that
number of moles = mass / molar mass or molarity x volume.
According to the above principle, we can say that
initial molarity x initial volume = final molarity x final volume.
So,
initial molarity of NaOH = 1 M,
initial volume = ?,
final molarity = 0.1 M,
And, final volume = 12.0 mL.
So,
Initial volume = final molarity x final volume/initial molarity
= 0.1 x 12/1
= 1.2 mL
Hence, The volume should be 1.2 mL

Summarizing Activities and Ideas
How did the lab activities help you answer the lesson
question, "How do atmospheric conditions influence
weather patterns?" What did you learn from conducting
this lab?
Answer:
Air pressure is influenced by the differences between hotter and cooler pockets of air, or fronts. ... When atmospheric pressure is low, air is pushed down toward the surface, meaning rain and moisture don't accumulate. This often also leads to high humidity near the surface of the Earth, where people experience weather.
Explanation:
Answer:
Sample Response: In the lab, I discovered the air pressure, air temperature, and relative humidity conditions that create snow, rain, thunderstorms, fog, and clear skies. I learned that low-pressure areas usually experience snowy, rainy, and stormy weather, and that high-pressure areas usually experience either foggy or sunny weather. Knowing how these atmospheric conditions influence weather help weather forecasters predict weather patterns through maps and other information.
Similarities between plasmolysis and haemolysis
Answer:
The main similarity between plasmolysis and hemolysis is that they both involve the destruction of a cell.
Explanation:
Similarities between plasmolysis and hemolysis are their involvement in the termination of the cell.
What is plasmolysis?The live protoplasm violently separates from the cell wall as a result of the loss of turgor. The vacuole is primarily responsible for the plasmolytic process.
Hemolysis is Plant cells subjected to hyperosmotic stress frequently exhibit plasmolysis as a reaction. T Living plant cells exhibit plasmolysis, which is reversible deplasmolysis.
Hemolysis is a process in which red blood cells are destructed. It is a process of rapturing of blood cells. It happens due to improper needle size and this is a disease, in which blue and white tinged happen in the eyes.
Therefore, both plasmolysis and hemolysis are subjected to the death of cells in the body.

When comparing a cell just before the first meiotic division with another cell of the same organism that is ready to start mitosis, we can correctly conclude that both cells present: * Select the correct option (s) I. Equal amount of DNA. II. Equal amount of chromatids on your chromosomes. III. Equal number of chromosomes.
Answer:
III. Equal number of chromosomes.
Explanation:
Comparison between two cells, one cell just before first meiotic division and other cell ready to start mitosis is that both the cells have equal number of chromosomes.
Both the cells have an equal number of chromosomes that is 2n (diploid), where n is 23 and total chromosomes are 46 in each cell but at the meiosis at the end meiosis produces four haploid (n) daughter cells and mitosis produces two diploid (2n) cells.
Hence, the correct answer is "III. Equal number of chromosomes.".
Animals are multi-celled consumers that take food into their body, where they digest it and absorb the released nutrients. An animal develops from an embryo (an early developmental stage) to an adult. Animal life began in the sea, and the Earth’s oceans still hold the greatest store of animal diversity. The majority of animals are invertebrates, meaning they do not have a backbone.

An immune response to a tissue graft will differ from an immune response to a bacterium because ________.
Answer:
Explanation:
They will differ because MHC molecules of the donor may stimulate rejection of the graft tissue as opposed to a receiver rejecting it in an immune response. That is because the MHC molecules are a group of genes that code for proteins found on the surfaces of cells that help the immune system recognize foreign substances and the surfaces are what is being transplanted during a tissue graft, meaning they are the ones that will ultimately reject the tissue graft operation.
