Which of the following are responsible for sending messages from the<br> midbrain to the cerebrum?
max2010maxim [7]

Answer: Brain stem

Explanation:

The brainstem can be defined as a structure which is present in between the midbrain and the cerebrum. This controls the flow of information from the brain and the rest of the body. It also controls the functions like breathing, heart rate, consciousness, sleep and wake cycle and blood pressure. The brain stem consists of pons, midbrain and medulla oblongata.

mafiozo [28]

Explanation:

This electron exchange results in an electrostatic attraction between the two atoms called an ionic bond.

If a 2 kg ball is traveling at a speed of 4 m/s, what is its kinetic energy?
MariettaO [177]

Answer:

  • Option D is the correct answer.

Explanation:

It is given that a 2 kg ball is traveling at a speed of 4 m/s, so we have to find its kinetic energy.

KE = 1/2 mv²

KE = 1/2 × 2×(4)²

KE = 1/2 × 2×16

KE = 16 J

<u>Some information about Kinetic Energy</u>.

Kinetic Energy is the energy an object has because of its motion. It is directly proportional to the velocity of the particle and its mass. Kinetic energy is given by,

  • KE = ½mv²
  • It occurs due to the motion of the particle.
  • If a particle at rest position, then the kinetic energy will be zero because that particle won't be accelerating.

Achondroplasia is a form of dwarfism inherited as a completely dominant trait. Two achondroplastic dwarfs have a dwarf child; la
yulyashka [42]

Answer:

There's 25% probability that their next child will be normal, and 75% of it being a dwarf.

Explanation:

Achondroplasia (A) is a dominant trait.

Two achondroplastic dwarfs (A_ x A_) have a dwarf child (A_) and a normal child (aa). The second child must be aa because if it had a dominant allele it would also be dwarf.

The only way for two achondroplastic parents to have a normal child is that <u>they are both heterozygous (Aa) for this gene.</u>

The cross Aa x Aa would produce the following offspring probabilities:

  • 1/4 AA - dwarf
  • 2/4 Aa - dwarf
  • 1/4 aa - normal

So there's 1/4=25% probability that their next child will be normal, and 3/4=75% of it being a dwarf.
