Answer:
See below
Explanation:
There are two different types of chromosomes coming from the ribosomes of a single cell. This is simply because you inherit traits from both your mother and father when you are given birth to. So, there are two types of genes which do not pair and therefore form two types of chromosomes.

In guinea pigs, the color of the fur is determined by a single gene with two alleles control. The brown allele (B) is dominant over the white allele (b). Two heterozygous guinea pigs are crossed. Draw a genetic diagram with the genotypic, phenotypic and ratio information of the P₁ and F ₁ generations of this cross.
Answer:
See
Explanation:
Given:
Brown allele (B) is dominant over the white allele (b).
It will be assumed that the alleles are not related to the X and Y chromosomes.
See attached diagram for details of the general case (for both homo-zygous and hetero-zygous parents)
For both parents hetero-zygous,
P1:
Genotype: Bb (100%)
Phenotype: brown (100%)
F1:
Genotypes : BB, Bb, bB and bb in equal proportions, i.e.
BB (25%), Bb (50%), bb (25%)
Phenotypes: 75% brown (from BB and Bb), 25% white (from bb)

Explanation:
The antibiotic susceptibility testing result of Staphylococcus aureus showed absence of growth on the zones of penicillin, ampicillin, tetracycline, chloramphenicol disk. Interpret the result.
Answer:
See Explanation
Explanation:
We define antibiotic susceptibility testing as an evaluation of the ability of antibiotics to inhibit bacterial growth. This test is necessary because certain bacteria may have developed resistance to certain antibiotics.
Hence, if the antibiotic susceptibility testing result of Staphylococcus aureus showed absence of growth on the zones of penicillin, ampicillin, tetracycline and chloramphenicol disk, then it implies that these antibiotics are all largely effective against Staphylococcus aureus and could be used for treatment of Staphylococcus aureus infection.

Define Vascular tissue?
Answer:
Vascular tissue is a complex conducting tissue found in vascular plants that is made up of several cell types. The xylem and phloem are the two main components of vascular tissue. Internally, these two tissues carry fluid and nutrients.

4. Ask a question about the relationship between two objects
Answer:
Is the two objects depends on each other or not?
Explanation:
If one body depends on the other object it means that there is a direct relationship between these two objects because if increase occur in one object, the value for other object also increases and vice versa while on the other hand, if the two objects independent or does not depend on each other, there is no direct or inverse relationship present among each other that effect one another.

Calculate the angle of impact for a blood droplet whose width is 6.8 mm and length is 7.2 mm.
1.)94°
2.) 16°
3.) 1°
4.) 71°
Answer:
71°
Explanation:
To obtain the angle of impact :
The length of blood stain = hypotenus
The width = opposite
Hence,
Hypotenus = 7.2 mm ; Opposite = 6.8mm
Angle of impact, θ = sin^-1(opposite /hypotenus)
θ = sin^-1(6.8/7.2)
θ = 70.8°
θ = 71°
Most of the solar radiation absorbed by Earth's surface is later radiated back into space as to which type of electromagnetic radiation?"
Answer:
The sun's visible wavelengths of radiation pass easily through the atmosphere and reach Earth. Approximately 51% of this sunlight is absorbed at Earth's surface by the land, water, and vegetation. Some of this energy is emitted back from the Earth's surface in the form of infrared radiation
Explanation:
When one glucose molecule travels through the glycolysis processes, four molecules of ATP are generated. Is it accurate to suggest that glycolysis produces two ATP molecules?
Answer:
No
Explanation:
Technically, this is inaccurate. To say that glycolysis produces two ATP molecules strays from the input of ATP needed. Overall, 4 ATP molecules are produced during glycolysis. However, there is an input of 2 ATP molecules at the beginning. Therefore, the correct statement would be that glycolysis produces 2 net ATP molecules, not that glycolysis produces 2 ATP molecules. (The word net makes a big difference!!).
In the picture below the purple circles represent salt molecules. Which way would

. The area of particle 1 is
2.5 mm². The area of particle 2
is 0.5 mm². The area of particle
1 is how many times as big as
the area of particle 2?
Answer:
The correct answer is - 5 times
Explanation:
Given:
area of P1 = 2.5
area of P2 = 0.5
Solution:
Let assume:
area of P1 is x times of the area of P2
then the equation would be:
=> 2.5 = x*0.5
=> 2.5/0.5 = x
=> 5 = x
Thus, area of P1 is 5 times to the area of P2
Need help please and thanks
Answer:
The concentration of the oxygen is higher outside of the cell and the oxygen will move inside or towards the cell since it is higher in the outside and lower inside the cell and the transport is passive and it doesn't require energy.

Adrian caught a virus while staying with his grandmother. A few years later. his mother and sister got the same virus. This virus could spread
through touch and direct contact. However, Adrian did not contract the virus
Why did he not get sick?
this time, even though he was living with his mother and sister.
2 Adrian's adaptive immunity remembered the antigens from the virus and gave him lifelong
immunity to it
- Adrian's innate immunity remembered the antigens from the virus and gave him lifelong immunity
to it.
.
Adrian's skin layer recognized the antigens and attacked them, which prevented the occurrence of
the virus again.
0
Adrian's innate immunity identified antibodies specific for the virus and targeted them against the
antigen.
0
Adrian's adaptive immunity produced a higher amount of specific antibodies for the antigen,
preventing the virus.
Answer:
The answer is A.
Explanation:
Adaptive immunity recognizes antigens of viruses.
What result allowed Dintzis to conclude that proteins are synthesized from the N terminus to C terminus
Answer:
The more newly synthesized peptides had greater levels of radiolabeled H
Explanation:
Using immature red blood cells (reticulocytes), Dintzis showed that polypeptide chains of hemoglobin were created from N-terminal to the C terminus during translation. Dintzis labeled with radioactive amino acids that were being actively translated, subsequently digested the translated proteins with trypsin and finally determined the amount of tryptic protein fragments. From this experiment, Dintzis observed that the radioactive products were concentrated in the C-terminus (i.e., labeled amino acids appeared first in the C terminal tryptic peptides), thereby showing that the direction of protein synthesis is from the N terminus to the C terminus.

A 14-year-old boy develops a pruritic vesicular rash on his face and hands 3 days after hiking in the woods. Which of the following are most likely to be involved in his illness?
a. Antibody, complement C5-9
b. Circulating immune complexes; complement C5a, neutrophils
c. Cytotoxic T lymphocytes
d. IgE, mast cells, histamine, cytokines
e. Lymphocytes, cytokines, macrophages
Answer:
The correct answer is: E) Lymphocytes, cytokines, macrophages.
Explanation:
Given the symptoms and how much time they took to appear, the 14-year-old boy seems to be having delayed-type hypersensitivity (also called Type 4 hypersensitivity), causing a reaction called Contact Dermatitis. Type 4 is the only type of hypersensitivity that does not require the intervening of an antibody to occur as it happens because of hapten-specific T cells that will generate inflammation and the tissue damage that is usually accompanied by it.
Delayed-type hypersensitivity is characterized for happening at least 48 hours after the contact with the antigen, and will involve activated T lymphocytes (specifically CD4+ Th1), which will secrete cytokines (most importantly Interferon Gamma and IL-2) thus attracting macrophages to the tissue to phagocyte the antigen and produce inflammation.
