What term refers to how fast blood traveled from its source? _________ refers to how fast blood traveled from its source to where it landed.
Answer:
Impact.
Explanation:
Science can be defined as a branch of intellectual and practical study which systematically observe a body of fact in relation to the structure and behavior of non-living and living organisms (animals, plants and humans) in the natural world through experiments.
In Science, the study of blood is generally referred to as serology.
Impact refers to how fast blood traveled from its source to where it landed.
This ultimately implies that, an impact is a measure of the rate at which blood travels from its source to where it lands. The four (4) phases of impact includes;
I. Displacement.
II. Retraction.
III. Contact and collapse.
IV. Dispersion.
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.
Generally, the right atrioventricular valve (AV) is also referred to as the tricuspid valve and is located on the right dorsal side of the human heart. The right atrioventricular valve (AV) comprises of three (3) leaflets (flaps) which opens and closes in order to allow for the flow of blood from the right atrium of the human heart to the right ventricle. Also, the right atrioventricular valve is saddled with the responsibility of preventing blood from flowing backward in the mammalian heart.

What could happen if two of the base pairs on this strand of DNA were switched?
In the DNA structure if the two base pairs exchange it leads to creating a mutation in the sequence and makes different proteins, hence option A is correct.
How do DNA base pairs change the protein?A mutation is any kind of change that leads to the creation of an abnormal protein, DNA has genetic information to synthesize any kind of protein.
The process of transcription by which genetic information stored in the DNA is passed to the RNA, which translate this information to make the protein.
Protein is the final output of the genetic information stored in the organism's cell, if any change in the DNA sequence it affects the final functional structure of the protien.
Therefore, different protein is the result of the base pairs on this strand of DNA being switched.

How are pluripotent and multipotent cells different?
a. A multipotent cell can differentiate into any cell type within the body, but a pluripotent cell cannot.
b. A multipotent cell can differentiate into any cell type within the body, but cannot become extraembryonic like a pluripotent cell.
c. Multipotent cells make up most adult somatic cells, but they are not stem cells like pluripotent cells.
d. A multipotent cell can become many different types of specialized cell within a tissue or organ, but it is more limited than a pluripotent cell.
Answer:
D. A multipotent cell can become many different types of specialized cell within a tissue or organ, but it is more limited than a pluripotent cell.
Explanation:
Both pluripotent and multipotent cells are types of cells that can form multiple types of cells in the body. They are very similar, but there is one key difference. Multipotent cells are more limited than pluripotent cells. Pluripotent cells can form all cell types that make up the body. An example of pluripotent cells are embryotic cells. Multipotent cells are more limited, although they can develop into more than one cell type. Examples of types of cells that belong to this group are adult stem cells and cord blood stem cells.

how soil gets affected by the repeated growing of crops in the same field how does use of fertilizers help the farmers
Answer:
Repeated growing of crops in the soil decreases the fertility of the soil as the crops use up the nutrients of the soil. ... Farmers replenish the soil of the depleted nutrition with the help of fertilizers or crop rotation. Fertilizers are chemical substances that are rich in a particular nutrient.
Answer:
a) repeated growing of crops in the soil results in decrease in soil fertility as the soil use up the nutrients of the soil .
b) as the farmers need to replenish the fertility of the soil they use chemical substances known as fertilizer . They help in maintaining and increasing the fertility content of the soil but overuse of fertilisers can harm the soil . So the fertilisers should be used in correct quantity .
A 20 N unbalanced force cause an object to accelerate at 1.5 m/s. What is the mass of the object?
Answer:
I believe it’s 13.33 m
Explanation:
Because a = Fnet / m
So if you plug the numbers in it’s : 1.5 m/s = 20n / m
Then you’ll want to cross multiply which it’ll be : 20n = 1.5m
Then you want to get m alone so you’ll divide 1.5 to both sides and that’ll leave you to
13.33 = m

Answer:
Evolution
Explanation:
Answer:
One species does not "turn into" another or several other species -- not in an instant, anyway. The evolutionary process of speciation is how one population of a species changes over time to the point where that population is distinct and can no longer interbreed with the "parent" population.

A woman with Type O blood and a man who is Type AB have are expecting a child. What are the possible blood types of the kid? 2. What are the possible blood types of a child who's parents are both heterozygous for "B" blood type?
The possible blood type of offspring, when a woman with type O and a man who is type AB are expecting a child are A and B.
What are the types of blood groups?There are four kinds of blood groups which are A, B, AB, and O, based on the presence of antigens in RBC. Blood groups A and B show co-dominance, while O is recessive.
When a woman with type O blood and a man who is Type AB are expecting a child, the possible blood types are A and B. 50% of the children would have A blood type, and 50% of children would have blood type B, which are heterozygous.
When Parents are both heterozygous for the B blood group, then the possible blood group of offspring would be 75% B blood type (25% are homozygous and 50% are heterozygous) and 25% O blood type.

Coastal regions of continents tend to have ______ climates than inland regions due to the stabilizing effects of steady ocean temperatures.
A.hotter
B.milder
C.colder
Answer:
B.milder
Explanation:
Water has a higher heat capacity than soil and rock, so the ocean takes much longer to heat and
to cool than the land.
Coastal areas will generally have more moderate temperatures than inland areas because of the
heat capacity of the ocean.
Coastal regions of continents tend to have milder climates than inland regions due to the stabilizing effects of steady ocean temperatures. Thus option B is correct.
What Are the Different Climate Types?
Five most important climate types are Tropical, Dry, Temperate, Continental and Polar
Tropical climate include the hot and humid zone of climate where the average temperatures of this zone is greater than 64°F and 59 inches of precipitation per year.
Dry climate refers to the zones which are dry as in this zone moisture is rapidly evaporated from the air leads to little precipitation.
Temperate climate refers to the zone with warm and humid summers with some mild thunderstorms and winters.
Continental type of climate shows warm to cool summers, very cold winters with some snowstorms, strong winds etc.
Polar climate zone refers extreme cold, even in summer, the temperatures below 50°F .
