Which description best defines blastocyst?

Physics
2 answers:
pentagon [3]3 years ago
6 0

Answer:

The correct option is C

Explanation:

A blastocyst consists of a mass of specialized cells (trophoblast), which is formed at the early stage during the development of the embryo. This means the embryo has not been formed yet (an embryo is formed when the amniotic sac develops).

An egg released from the ovary is wrong because it is a single cell (that has nothing to do with pregnancy on its own) while "A fertilized egg" is wrong because a fertilized egg consists of just two cells; a sperm cell and an egg cell".

An alligator swims to the left with a constant velocity of 5 S/M
Goshia [24]

Answer:

t = 0.85[s]

Explanation:

To solve this problem we must make a complete description of this. By doing an internet search, we find the description of this problem as if of the question.

<u>Description</u>

<u />

"An alligator swims to the left with a constant velocity of 5 m s when the alligator season a bird straight ahead the alligator speeds up with a constant acceleration of 3 m/s^2 leftward until it reaches a final velocity of 35 Ms left work how many seconds does it take the alligator to speed up from 5 m/s to 35 m/s".

To solve this problem we must identify the initial data:

v0 = initial velocity = 5 [m/s]

a = acceleration = 3 [m/s^2]

vf = final velocity = 35[m/s]

t = time = ?

Using the following kinematic equation, we can find the time that is required.

v_{f}=v_{0}+a*t\\35=5+35*t\\t=\frac{35-5}{35} \\t=0.85[s]
