QVII) Give reason for the following:
1. Light travels in a straight line
Shadows are evidence of light travelling in straight lines. An object blocks light so that it can't reach the surface where we see the shadow. Light fills up all of the space before it hits the object, but the whole region between the object and the surface is in shadow.
Explanation:
Since the wavelength of light is very small as compared with the size of ordinary object and diffraction of light is not easily noticed and hence the light appears to travel in a straight line.

Match the following terms describing electrical events with the correct phases of the cardiac cycle.
Question Selected Match
The ventricular muscle cells depolarize at the start of this phase.
During this phase, Na+ entry through the funny channels causes the pacemaker potential of SA nodal cells to gradually become less negative until it reaches threshold.
The ventricular muscle cells repolarize right before this phase.
The cytosolic concentration of calcium in the contractile cells of the ventricle is highest during this phase.
All Answer Choices
A. isovolumetric contraction
B. ventricular ejection
C. ventricular filling
D. isovolumetric relaxation
Answer:
1. Isovolumetric contraction.
2. Ventricular filling.
3. Isovolumetric relaxation.
4. Ventricular ejection.
Explanation:
In Human anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.
Generally, the cardiac cycle occurs in two (2) stages;
Diastole : in this stage, the ventricles is relaxed and would be filled with blood.
Systole: at this stage, the muscles contracts and thus, allow blood to be pushed through the atria.
The following terms describe the electrical events with the correct phases of the cardiac cycle in mammals (human beings);
1. Isovolumetric contraction: The ventricular muscle cells depolarize at the start of this phase. During this phase, the pressure in the atria is lower than the pressure in the ventricles while the pressure in the arteries is higher than the pressure in the ventricles.
2. Ventricular filling: During this phase, Na+ entry through the funny channels causes the pacemaker potential of SA nodal cells to gradually become less negative until it reaches threshold. It causes the atria to contract at the end of the phase.
3. Isovolumetric relaxation: The ventricular muscle cells repolarize right before this phase. During this phase, all of the four (4) cardiac valves are closed while all of the four (4) chambers are relaxed.
4. Ventricular ejection: The cytosolic concentration of calcium in the contractile cells of the ventricle is highest during this phase. Also, the atrioventricular (AV) valves are closed while the semilunar valves are open.
Two individuals that are heterozygous for tongue rolling mate. What are the predicted genotypic and phenotypic ratios for this cross?
Answer:
Genotypic ratio = 1:2:1
Phenotypic ratio = 3 tongue rollers : 1 non-tongue roller
Explanation:
This question involves a gene coding for the ability to roll the tongue or not in humans. The allele for tongue rolling (R) is dominant over the allele for non-tongue rolling (r).
According to this question, two individuals that are heterozygous for tongue rolling mate i.e. Rr × Rr. The proportion of offsprings that will be likely produced from this cross will be: RR, Rr, Rr, and rr.
- Offsprings with RR, Rr, Rr are tongue rollers
- Offsprings with 'rr' are non-tongue rollers.
Hence, the predicted genotypic and phenotypic ratio are as follows:
Genotypic ratio = 1 RR :2Rr :1rr
Phenotypic ratio = 3 tongue rollers : 1 non-tongue roller

In base pairing for the translation of DNA to mRNA, which nitrogen base complements Adenine?
Answer:
Adenine and thymine form base pairs that are held together by two bonds, while cytosine and guanine form base pairs that are held together by three bonds. Bases that bond together are known as complementary. During transcription, DNA is converted to messenger RNA (mRNA) by an enzyme called RNA polymerase.

Explanation:
Why is it important that a protein keeps its shape?
The shape of a protein keeps its amino acids from changing sequence.
The shape of a protein keeps it from breaking up into loose amino acids.
The shape of a protein allows it to perform several different jobs.
The shape of a protein allows it to perform its particular job

The difference between an open and a closed circulatory system is...
Answer:
In the closed circulatory system, blood is confined to a heart and blood vessels, whereas in an open system, hemolymph (blood) moves from a heart through vessels into interconnected spaces called a "hemocoel."
Explanation:
An open circulation the blood is not blood vessels, it instead is pumped into a cavity called Hemocoel.
A closed circulatory system, the blood is pumped through vessels SEPARATE from the interstitial fluid of the body.
Which mutation would be harmful to the farming industry?
a mutation that causes cows to produce more milk
a mutation that causes sheep to have more wool
a mutation that causes female pigs to have less offspring
a mutation that causes an increased crop yield
Answer:
a mutation that causes female pigs to have less offspring
Explanation:
Answer:
A mutation that causes female pigs to have fewer offspring
Explanation:
In the farming industry, more product is better. If cows produced more milk, farmers would make more money.
If sheep produced more wool, the farmers would profit.
If there was an increased crop yield, the farmers would benefit.
However, fewer pigs means less money, so that is the only possible answer.

In 1980, Mount St. Helens erupted in Washington State. Hot air and debris destroyed the surrounding forest. Since
then, scientists have been studying this area and are observing the ecological succession that is occurring.
Which graph shows what scientists have most likely observed about the species diversity in the area since 1980?
Species Diversity
Species Diversity
Time (years)
Time (years)
ecies Diversity
ecies Diversity
Answer:
Helens' vicitims died by asphyxiation from inhaling hot volcanic ash, and some by thermal and other injuries. The lateral blast, debris avalanche, mudflows, and flooding caused extensive damage to land and civil works. All buildings and related manmade structures in the vicinity of Spirit Lake were buried. So it would be the graph that goes down.
Explanation:
The graph that depicts the that scientists have mostly observed diversity of species in that area is graph A.
What was the impact of Mount St. Helen's eruption?The 1980 Mount St Helens eruption in Washington state leads to the release of hot air with debris that destroyed the forests ad surrounding lands.
The victims died from inhaling the gas and others got injured. The lateral blasts and debris avalanche, along with mudflow created extensive damage to land and property.

How are the smallest ocean waves produced?
A.Weak winds that blow for short periods of time over great distances.
B.Weak winds that blow for long periods of time over small distances.
C.Weak winds that blow for short periods of time over small distances
D.Weak winds that blow for a long time over a great distance.
Answer: the answer is C
Explanation:
Answer:
c!
Explanation:
For a wave to effectively be produced there need to be large wind, long period of time and a large distance of water. If they are all reduced, then there would be a reduction in the intensity of the wave.

specificity of communication by the nervous system compared to the endocrine system
Answer:
Like the nervous system, the endocrine system is a regulatory system. However, instead of using electrical impulses for signaling, it produces and uses chemical signals called hormones, which travel through the bloodstream and control the actions of cells and organs.
