Are heated air and wind shear the cause for severe storms? Explain.

Answers

Answer:

Yes, they are very much the main cause of severe storms because the heat molecules get into the atmosphere and clouds, causing chemical reactions and damage. At some point in time, the energy built up, as well as the damage done, must undo itself. This is done through a storm. It is the environment's way of cleaning itself.

As a part from this video below states, wind shear is a leading cause in severe storms.

A cross between a yellow snake and a blue snake produces offspring that are all green. What type of inheritance is this?

Answers

Answer:

co dominance

Explanation:

codominance is a type of inheritance in which both allels are dominat over each other and the two allels are expressed to an equal degree in an offspring,that is why the cross between yellow and blue snake give another green colour offsprings in stead of giving all blue or all yellow offsprings depending on which allel is dominant.

as example we can take human blood group AB which is inherited from blood group A and B and both allel A and B are dominant over each other.

The synapses that are nearer to the axon hillock would bring the initial segment closest to the threshold based on spatial summation.

What is neuron synapsis?

In neurosciences, the term synapsis makes reference to the connection between two nerve cells (neurons).

Synapsis is produced by the connection between axons and dendrites among different neurons.

Spatial summation refers to the start (trigger) of the action potential in neurons via two or more presynaptic cells.

Answers

Most of the time in lichen, ascomycetes or basidiomycetes form the fungal part with several hyphae layers enveloping the photosynthetic algal part.

Lichens

Lichens are composite organisms. They are formed from a symbiotic relationship between fungi and algae. The fungi provide shelter and some vital minerals for the algae while the algae provide food via photosynthesis.

Oftentimes, the fungi components are usually ascomycetes or basidiomycetes. They form a network of hyphae around the photosynthetic algae as a form of protection.

What does fossil evidence show about evolution?

Answers

Answer:

Answer below

Explanation:

Fossils provide physical examples of what organisms have looked like over time. For example, we can look at giraffes over time, who have evolved to have had long necks. When we look as fossil records of giraffes and similar species, we see that the longer ago that animal lived, the shorter their neck was, and as time progresses, the neck gets longer. However, we also see that in general the giraffes with longer necks, regardless of time period, will have lived longer and healthier lives (we can usually tell this just by how big the fossil is), as with longer necks the animal was able to reach more food and live longer. That giraffe then reproduced and shared their longer neck traits, while those with genetic markings to make their necks shorter will have died before reproducing. Therefore, we can see all forms of evolution through fossils.

List all the gametes that are possible with each of the following genotypes.
a. Aabb
d. AABb
b. AaBB
e. AAbb
C. AaBb
f. aabb

Answers

All the possible gametes for Aabb would be Ab and ab; that of AABb would be Ab and AB; that of AaBB would be AB and aB; that of AAbb would be Ab; that of AaBb would be AB, Ab, aB, and ab; and that of aabb would be ab respectively.

Gametes formation

The formation of gametes for a dihybrid involves the crossing of the two traits involved.

Thus: Aabb is equivalent to crossing Aa and bb

             

                           Aa   x   bb

                       Ab   Ab   ab   ab

Hence, all the gametes would be Ab or ab.

For AABb:                     AA   x   Bb  =   AB   Ab   AB   Ab

The gametes are either AB or Ab

For AaBB: the gametes are either AB or aB

For AAbb, only Ab gametes are produced

For AaBb: the gametes would be AB  Ab   aB and ab

For aabb: only ab gametes are produced.
