What are the strengths and limitations of this model?

Please choose the answer that best completes the blanks of this sentence in the correct order. The ______ plate method involves

77julia77 [94]

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:

During DNA replication, the leading strand is synthesized in the 5' to 3' direction. The strand that runs away from the replication fork is synthesized in Fragments because DNA polymerase cannot synthesize in the 3’ to 5’ direction.

Explanation:

A replication fork has one strand called the leading strand, it is synthesized continuously from a single primer on the leading strand template and grows in 5'-3' direction.
The leading strand grows in the same direction in which the replication fork grows.
The other strand is the lagging strand that is unveiled by the growing replication fork. It proceeds in the direction opposite to the movement of growing replication fork.
The lagging strand is synthesized discontinuously because the DNA polymerase can add nucleotides only to the 3' end of a primer.
These short pieces of synthesized DNA are okazaki fragments.Okazaki fragments are joined later by ligase.

This is it thank you

vova2212 [387]

Answer:

1. it looks like a twisted ladder

2. DNA replication is the process by which DNA makes a copy of itself during cell division. ... The separation of the two single strands of DNA creates a 'Y' shape called a replication 'fork'. The two separated strands will act as templates for making the new strands of DNA.

3.(deoxyribose) and a nitrogenous base (in color).

Which of the following best describe gas particles?

timama [110]

Answer:

a, b, d (see below)

Explanation:

So, looking at the 3 states of matter:

Solid - holds a shape and is made up of particles that vibrate in place (because particles are always moving no matter what)

Liquid - holds shape of its container and has particles with some space in between them that allow them to flow

Gas - holds shape of its container and has particles with huge gaps of space between them that are always, constantly moving and zooming around

Refer to the image below for a better visual understanding.

So, now, looking at the answer choices:

a) moving randomly

Yes. They are—they're speeding around super fast all the time.

Every time heat is added to something, the particles start loosening up and moving. A lot.

So when you add heat to a solid, it starts loosening up and moving around until it becomes flowy enough to be a liquid. Then, if more heat is added, the particles moving faster and loosen up even more until they're a gas.

Imagine doing that one more time, and you'll have plasma. As you may have guessed it, plasma moves super fast

b) collide into each other

Yes. Because they're moving so fast and uncontrollably all the time, they're bound to have rammed into one another a few or more times.

Imagine bumper cars at a carnival, except the speed of each car is sooo fast that you could be on a highway. You're probably going to hit someone, which is why bumper cars are not that fast in reality. For safety reasons.

c) move slow

No. Since we know that they're always zooming around (refer to my bumper car example above, in bold), they obviously can't be slow.

d) high kinetic energy

Yes. Anything moving (a.k.a. in motion) has kinetic energy. If gases zoom super fast 24/7, they will have high kinetic energy.

Having high kinetic energy means that the something is moving really fast or a lot. In this case, gases are both.

e) moving orderly

No. They're moving everywhere and really fast, so they have no control over how they move because of how fast they are.

(refer to my bumper car example in answer b, in bold)
