Please choose the answer that best completes the blanks of this sentence in the correct order. The ______ plate method involves spreading an inoculum onto the surface of a plate in a pattern that results in isolated colonies in some areas of the plate after incubation, whereas the ______ plate method involves diluting an inoculum into several melted agar tubes and then adding their contents into plates for solidification and incubation.
Answer:
streak, pour
Explanation:
The streak method is the most popular technique used to isolate specific bacteria from a sample containing different microorganisms. In this technique, a sterile loop is employed to obtain an uncontaminated microbial culture. Colony picking refers to the process where colonies of pure bacteria are selected in order to duplicate them by transferring them into new agar plates. Moreover, the pour plate method is the most popular technique employed to count the number of colony-forming bacteria (i.e., bacteria/ml) in a specimen. The pour plate method consists of dropping the sample on a sterile plate and subsequently molten-cooled agar is then poured into the plate and mixed well with the inoculum.
Answer:
streak, pour
Explanation:
The streak plate method involves spreading an inoculum onto the surface of a plate in a pattern that results in isolated colonies in some areas of the plate after incubation, whereas the pour plate method involves diluting an inoculum into several melted agar tubes and then adding their contents into plates for solidification and incubation.

how can you differentiate between littoral zone and limnetic zone in a pond ecosystem ?
Explanation:
The limnetic zone is the open and well-lit area of a freestanding body of freshwater, such as a lake or pond. Not included in this area is the littoral zone, which is the shallow, near-shore area of the water body.
Three genes (A, B, and C) are located on different chromosomes. In a cross between
AaBCC and AabbCc (P generation) what would be the probability of seeing an
offspring with the genotype AAbbCc in the Fı generation (assuming no linkage)?
Answer:
b, a, c
Explanation:
Since recombination frequency is directly proportional to the distance between genes, the values are used to locate genes on a chromosome. Here three genes a, b and c can assume any of three linear sequences: a-b-c or a-c-b or b-a-c, which depends on the gene present in the middle. Here, recombination frequency for a and b (X) = 20%, that for a and c (Y) = 8% and for b and c (Z) =28%. As we can see that Z = X + Y or 28 = 20+8 which means that genes b and c are present at extremes and a is in the middle. Thus, the sequence of genes is b-a-c.
Highly toxic chemicals that persist in the environment have been associated with disruption of the: immune system. reproductive system. nervous system. All of these are correct.
Answer:
All of these are correct.
Explanation:
Immune system, reproductive system and nervous system are adversely affected by the contact of highly toxic chemicals because toxic chemicals have materials which is harmful for the cells that the cause of cell death or damaged the structure of the cell due to which the cell can't perform its function efficiently. All the system i.e. Immune system, reproductive system and nervous system are made up of cells so if the cells are damaged by these toxic chemicals the body systems are also negatively affected.
which one of the following did not constitute the seven contrasting pairs studied by mendel in pea plant?
A.shape of the leaves
B.height of the plants
C.colour of the flower
D.position of the flower
Answer:
A. Shape of the leaves
Explanation:
Mendel chose seven characters of the pea plant to study.
They are:
1. Flower colour
2. Flower position
3. Stem length
4. Pod shape
5. Pod colour
6. Seed shape
7. Seed colour
Shape of leaves was not observed by Mendel.
Inertia is the tendency of an object to resist a change in motion.
A. 1st Law
B. 2nd Law
C. 3rd Law
(will mark brainliest if you answer 6,7,&8 pls)
Answer:
6) Inertia is 1 Law
7) Acceleration is 2 Law
8) Should be acceleration too, 2 Law
Hope This Helps!

Explanation:
6:
Answer: Newton's first law of motion,
Explanation: Inertia is the tendency of an object to resist a change it its motion. Describe how inertia affects motion. If an object is already at rest, inertia will keep it at rest. If the object is already moving, inertia will keep it moving.
7:
Answer: The second law
Explanation: The second law shows that if you exert the same force on two objects of different mass, you will get different accelerations (changes in motion). The effect (acceleration) on the smaller mass will be greater (more noticeable).
8.
Answer: Newton's Second Law
Explanation: The second law of motion explains the relationship between force, mass, and acceleration. The law states that the acceleration of an object depends on the mass of the object and the amount of force applied. Newton's second law of motion is also called the law of force and acceleration.
answer this genotype question please!!!
Answer:
YY
Explanation:
It's co-dominate, meaning both traits show, but don't blend (Ex: Red + White = Red With White Stripes) (Ex: Blue + Red = Red With Blue Spots)
Answer:
YY
Explanation:
It is YY because these genes do not blend together with other genes.

Which is in order from smallest to largest?
a. cell, organ, tissue, organ system, organism
b. cell, tissue, organ, organ system, organism
c. cell, tissue, organ, organ system, organism
d. cell, tissue, organism, organ, organ system
Answer:
B or C??
Explanation:
It's not D because organism is the largest. It's not A because an organ is larger than a tissue. A Tissue is a group of cells.
B and C are the exact same

Answer:
When antibodies attach to an antigen (think a lock–key configuration), it signals other parts of the immune system to attack and destroy the invaders. This is how the human body develops immunity (acquired) to a particular disease. But some germs and viruses are very adaptive.

Looking at North America, which of the layers formed most recently? Explain your reasoning.
Urgent, please!!
Answer:
Sedimentary rocks are deposited one on top of another. Therefore, the youngest layers are found at the top, and the oldest layers are found at the bottom of the sequence.
Answer:
G
Explanation:
Because this is the latest layer formed. On the other hand, you can see that A has formed its layer thousands and thousands of years ago.
