75km/hr due east

Explanation:

The velocity of the train will be 75km/hr due east.

  • Velocity is given as the rate of change of displacement with time.

            Velocity = \frac{displacement}{time taken}

  • Velocity is a vector quantity that has both magnitude and directions.
  • It is different from speed because it has the directional attribute.
  • From the given data, we know that the train is moving at 75km per hour. This is the speed of the train.
  • If we incorporate the direction then we have its velocity.

This is evident due to the Decerebrate posturing, which is characterized by abnormal extension in response to painful stimuli, that indicates damage of the midbrain. On the other hand, damage to the diencephalon or cortex, abnormal flexion, occurs when a painful stimulus is applied. While medulla damage results in flaccidity.

What is one change that would cause more water to evaporate from a stream?
Svetllana [295]

Evaporation

Explanation:

Evaporation is one change that would cause more water to evaporate from a stream.

Evaporation is a phase change in which liquid is changed into its gaseous form.

  • When a substance is heated from solid to liquid, it melts.
  • After melting, additional heat causes a phase change that allows for the liquid to change to gases.
  • In the water cycle, the sun provides heat energy that causes surface water in streams to be heated.
  • This leads to evaporation of the surface water into the atmosphere where they can be condensed to form precipitation.

In sweet pea, red flower color is controlled by two genes involved in the anthocyanin pathway, A and B. Both genes are required
Alex787 [66]

Answer:

The dihybrid ratio we expect in the offspring is 9:7.

Explanation:

This is an example of complementary gene interaction, which is the non allelic interaction or genes, where the prominent genes at heterozygous loci may complement each other by complementing recessive alleles at the respective loci.

So in this case of  complementary gene interaction, the individuals that are A-bb or aaB- or aabb will have the same set of observable features (phenotype) but only A-B- individuals will how the dominant phenotype.
