HELP ME PLEASEIn which prenatal stage is a fetus' genitalia clearly male or female?
A. zygote stage B. germinal stage C. embryonic stage D. fetal stage

Answers

Answer 1

Answer:

In the fetal stage, the genitalia of a fetus is developed. Thus option D, the fetal stage is correct.

What is the prenatal stage?

The time period from the formation of the zygote to the parturition is called the prenatal stage and it is also known as the antenatal stage. In this stage, division and differentiation of the zygote take place to form an embryo, and then the development of the embryo to form a fetus.

The prenatal stage consists of 3 stages:

1) Germinal stage

2) Embryonic stage

3) Fetal stage

The time period of the first two weeks after conception is known as the germinal stage, from the third to eighth week is the embryonic stage, this stage begins after implantation, and from the ninth week to the parturition is the fetal stage. The genitalia of a fetus can be clearly differentiated by the twelfth week.

Therefore, option D, the fetal stage is correct.

Help fast please!!!!!A new solar system with two planets of equal mass - Planet X and Planet Y - is discovered. Planet X is closest to the sun.

What is the sun's gravitational pull on Planet Y as compared with Planet X?

A.
Because Planet Y is farther from the sun, the sun's gravitational pull on Planet Y is less than the sun's gravitational pull on Planet X.
B.
The sun's gravity repels Planet Y with more force than it repels Planet X, which is why Planet Y is farther away.
C.
Because Planet Y is farther from the sun, the sun's gravitational pull on Planet Y is more than the sun's gravitational pull on Planet X.
D.
The sun's gravitational pull on Planet Y is equal to its gravitational pull on Planet X because distance does not affect the sun's gravity.

Answers

We're told that the planets have EQUAL MASS.

If that's true, then the strength of the gravitational forces between
each planet and the star depends only on the distance between
them ... the farther a planet is from the star, the smaller the
gravitational forces are IF we're talking about planets with
equal masses.

Planet-X is closer to the star, and Planet-Y is farther from it.
From this we know that the gravitational forces between the
star and Planet-X are greater, and the forces between the star
and Planet-Y are smaller.

'A' says this.

'B' is totally absurd, because it talks about gravity repelling things.

'C' says exactly the opposite for the two planets.

'D' says that distance doesn't matter. We know this is absurd,
simply because we're never pulled toward Jupiter in our daily life.

the answer is A

How does polarizing filter reduce glare?

Answers

Polarizing filter reduces glare by allowing glares only in a particular direction to pass through.

Glare are usually light vibrations in all directions, but the filter reduces the glare by allowing only light vibrations in a particular direction to pass through it, and hence cutting off other vibrations. Hence the glare becomes reduced.

Which of these components is not necessary for current to flow in a series or parallel circuit?A. wire
B. switch
C. resistor
D. All of these are needed.

Answers

Current requires only an EMF source ... like a battery, or a current already flowing ... and a conducting path ... like wire, ionized air, or something dissolved in water. A switch isn't needed unless you want a quick, easy way to STOP the current. A resistor isn't needed unless you want to be able to dissipate some energy from the current, or limit its magnitude.

Heeeelllllllpppp I need this right now Which type of friction acts on an object that is not moving?
O static fluid
O fluid friction
O sliding friction
O rolling friction

Answers

The friction which acts on the object that is not moving is static friction, so, option A is correct.

What is friction?

Between two surfaces that are sliding or attempting to slide over one another, there is a force called friction. For instance, friction makes it challenging to push a book down the floor. Friction always moves an object in a direction that is counter to the direction that it is traveling or attempting to move.

Static friction is 0 for an object at rest on a level surface. Static friction generates an equal and opposite force that holds the book at rest if you push horizontally with a small force.

The static friction force grows to meet the force as you push harder. The book eventually moves when the maximum static friction force is reached.

Thus, the friction is static.

Plates move apart at ____ boundaries.a. convergent
c. divergent
b. stable
d. transform

Answers

The correct answer is C. divergent. Divergent boundaries are something like lines found between two tectonic plates. These constructive boundaries, or extensional boundaries, are formed and exist between two tectonic plates that move away from each other. Convergent would thus be where they meet. This is all according to the tectonic theory.

Plates move apart at divergent boundaries, which occur when two tectonic plates are moving away from each other.

Plates move apart at divergent boundaries. Divergent boundaries occur when two tectonic plates are moving away from each other. This movement creates a gap or rift between the plates where molten rock rises to fill the space, forming new crust. The best example of a divergent boundary is the Mid-Atlantic Ridge.
