Answer: Pumpkin
Explanation:
Cucumbers have a lot of seeds but are not squash.
Apples are neither squash nor do they have that many seeds.
Pumpkins are squash and have a lot of seeds so this must be the correct answer.
Melons have a lot of seeds but are not considered squash even though they are related.
Answer:
Hormones are able to travel the body but only affect certain cells because only those target cells have receptors for that particular hormone. Some hormones bind to receptors on the surface of target cells. Others enter the cells and bind to receptors in the cytoplasm or nucleus.
was added to 9.9 ml of sterile buffer. After thorough mixing, this
suspension was further diluted by a 1/100 dilution followed by a
1/10 dilution. One-tenth of a ml of this final dilution was plated
on agar plates. After incubation, 52 colonies were present. How
many colony-forming units were present in the total 10 gram sample
of hamburger?
Answer:
5.2 × 10 ⁹ cfus
Explanation:
Using the dilution factors
0.1 ml of the final dilution has 52 colonies
1 ml will have approximately 520 colonies
10 ml of the final sample will have 5200 colonies
at 1 / 100 dilution
1 ml of the sample will have 5200 colonies
100 ml of the sample will have 520000 colonies
1 ml of the 0.1 ml + 9.9 ml has 520000 colonies
10 ml will have 5200000
at the second stage of the dilution
0.1 ml of the slurry had 5200000 colonies
1 ml will have 52000000 colonies
10 ml will have 520000000 colonies
100 ml of the initial sample ( 10 grams + 90 ml ) = 5200000000 colonies =
5.2 × 10 ⁹ cfu
convection, conduction and radiation is the correct answer because heat flows from hot to cold. The heat flows from hot objects to cold objects whether the heat transfer is occurring by convection, conduction, or radiation. Heat flows from warmer substances to cooler substances until they reach the same temperature.
Answer is Communicable disease can be spread by inanimate objects, such as doorknobs.
The causal organisms of some of the communicable diseases are bacteria and viruses. The communicable diseases such as common cough and cold can be transmitted to a healthy person by indirect contact with contaminated substances such as food, air, soil, feces, equipment, objects including doorknobs, remote controller, etc.
(c) _____% of the human genome is comprised of A.
Enter your answer as three numbers separated by commas (example: 12, 26, 32).
Answer:
The correct answer will be- 21, 29, 29
Explanation:
In a DNA sequence, the nucleotide base pairs on one strand of DNA are complementary to the base pair on other strand of DNA.
According to the Chargaff rule, Adenine binds Thymine and Cytosine binds Guanosine which shows that the amount of A will equal T and the amount of G will equal C.
Therefore, when the amount of C is 21%, then the amount of G will be 21%.
To find amount of AT= 100-GC
AT= 100-42
AT= 58%
So, AT/2= 29% each
Thus, A=T= 29%
G=C=21%
