Answer:
A
Explanation:
Viruses don't contain organelles.
The statement which is true with respect to the cell and viruses is as follows:
Cells contain organelles, whereas viruses do not contain organelles.Thus, the correct option for this question is A.
What is a Cell?A Cell may be defined as the basis structural and functional unit of life. All living organisms are made up of cells. Cells are required for organisms in order to accomplish their metabolic activities, growth, development, etc.
Most living cell significantly consists of cell organelles except for bacteria. Viruses are non-cellular. So, these do not have organelles. Viruses simply utilize the host machinery in order to multiple and reproduce.
Therefore, cells contain cell organelles while viruses do not contain organelles because they lack cells. Thus, the correct option for this question is A.

"Brown eyes are dominant over blue eyes. If two brown eyed parents have a child with blue eyes, what does it mean about the parent’s genotype?"
Answer:
Because brown (B) is dominant over blue (b). Two parents who are Bb and so have brown eyes each have a 50% chance of passing a b to their child. ... By the old genetic rules, two blue-eyed parents would both be bb and so could only pass b to their kids.

6. Examples include Wiliams syndrome and Cri du chat syndrome
7. Occurs when pieces of a chromosome are lost
A. Duplications

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.

Explanation:
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.".
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.

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.

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.

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.
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.

If you have a strand of DNA that reads 3'TACGCGATAGGCAAATT5'. 1. Give the corresponding strand of mRNA 2. Assuming the last condon is a stop codon, will this mRNA strand code correctly for a five amino acid protein
Answer:
1. 5'AUGCGCUAUCCGUUUAA3'
2. No
Explanation:
1. Considering the base-pairing rule, the substitution of the thymine base in DNA with Uracil base in the corresponding mRNA, and the directionality in DNA/RNA; the corresponding mRNA sequence from the DNA strand 3'TACGCGATAGGCAAATT5' would be: 5'AUGCGCUAUCCGUUUAA3'
2. A codon is made up of 3 nucleotide bases. There are 17 nucleotide bases in the mRNA and if the last codon is a stop codon, it means 14 nucleotide bases would be translated. When 14 is divided by 3, there would be 4 complete codons and 2 nucleotide bases would remain. Hence, the mRNA cannot code correctly for a five amino acid protein.
Answer:
5'AUGCGCUAUCCGUUUAA3'
No, the mRNA strand code will not have a five amino acid protein.
1 Explanation:
Use this formula and it can not be the other way around unless stated:
T translates to A
A translates to U
G translates to C
C translates to G
Because the congruent strand is reciprocal to the mRNA strand, the original 3' - 5' would need to be flipped to 5' - 3'
Thus the answer for 1. is 5'AUGCGCUAUCCGUUUAA3'
2. Explanation:
Let's break the sequence into codons.
AUG - CGC - UAU - CCG - UUU - AA
AUG states for the start point so it doesn't count as a five amino acid protein, thus eliminating it.
CGC - UAU - CCG - UUU - AA
As stated in the question, the last codon is the stop codon, thus eliminating that as well.
CGC - UAU - CCG - UUU
Now the remaining codon would be only 4, not five thus it wouldn't have five amino acid proteins.
Hope this helps!
