Answer:
A reflex is made possible by neural pathways called reflex arcs which can act on an impulse before that impulse reaches the brain.
Answer:
If you are talking about reflexes in the body
Explanation: Some functions are involuntarily performed, such as breathing, digestion, heart beating, eye reflexes, etc., but some involuntary actions have voluntary control to a certain extent – examples are breathing, salivation, deglutition (swallowing), defecation, micturition (urination) and others.

If a woman is heterozygous for widow's peak
(widow's peak is dominant over a smooth hairline) has children with a man with a smooth hairline, what
are the possible phenotypes of their children?
It is impossible to determine the possible phenotypes.
O All of their children will have a widow's peak.
O None of their children will have a widow's peak.
It is possible for their children to either have widow's peak or a smooth hairline.
Answer:
It is possible for their children to either have widow's peak or a smooth hairline.
Explanation:
Let's say that the widow's peak allele is W (dominant) and the smooth hairline is w (recessive).
A woman heterozygous for widow's peak is Ww. A man with a smooth hairline must have two copies of the smooth allele since it is a recessive trait, so he must be ww.
The cross is Ww x ww
W w
w Ww ww
w Ww ww
There is a 50% chance that the children will have the genotype Ww, and therefore have a widow's peak. There is a 50% chance the children will be ww, and will therefore have a smooth hairline.
So, It is possible for their children to either have widow's peak or a smooth hairline.
The Rocky Mountains are known for beautiful scenery. Which processes of the Rocky Mountains most likely required the longest period of time to occur?
growth of plants and trees
formation of valleys from glaciers
large uplift of the land from tectonic forces
large accumulation of snow on the mountaintops
Answer:
Large uplift of land from tectonic forces
Explanation:
The processes of the Rocky Mountains most likely required the longest period of time to occur is large uplift of the land from tectonic forces. Thus, option C is correct.
What are rocks?
When compaction and cementing happens then, a sedimentary rock is made. The rock is made when layers of minerals are stacked upon each other. These minerals include dirt, soil, sand, and other stuff. Overtime these minerals will make the layers that you see in a sedimentary rock. So, the older minerals will be on the bottom while the younger minerals will be on the top.
The Sedimentary rocks refers to the type of rock that is formed from pre-existing rocks or pieces of once-living organisms. They mainly emerged from deposits that accumulate on the Earth's surface and often have distinctive layering or bedding.
The common types of sedimentary rocks include sandstone, limestone, and shale. They often start as sediments carried in rivers and deposited in lakes and oceans and when buried, the sediments lose water and become cemented to form rock.
Therefore, option C is correct.

The swallowing phase where the velopharynx closes forcefully and larynx completely closes at 3 levels is the...
a. Tongue preparatory phase
b. Pharyngeal transport phase
c. Oral transport phase
d. Laryngeal transport phase
Answer:
b. Pharyngeal transport phase
Explanation:
During the pharyngeal phase, the vocal folds close to keep food and liquids from entering the airway.
Swallowing the velopharynx closes forcefully and the larynx completely close at the level of the pharyngeal transport phase this action seal the airway passage, hence option b is correct.
What is swallowing ?According to where the bolus is located, the swallowing process is often split into oral, pharyngeal, and esophageal phases. When consuming solid food vs drinking liquid, the food moves differently through the oral cavity and into the oropharynx.
The tongue closes the oropharynx while it is in the pharyngeal phase. The proximal pharyngeal wall and soft palate serve as a barrier to the nasopharynx.
The laryngeal entrance is sealed off by the vocal cords and arytenoids, and the epiglottis swings down to cover the laryngeal vestibule. These acts close up the pharyngeal cavity's airway.
Therefore at 3 levels, the velopharynx closes forcefully and the larynx completely closes in the pharyngeal transport phase action to seal the airway passage, hence option b is correct.

Explanation:
Compare and contrast serine proteases and aspartic proteases. Not all answers will be used. Serine protease Both Aspartic protease
Answer: The main similarity between the serine protease and aspartic protease is that these enzymes catalyze the break down or hydrolysis of the peptide bonds.
Explanation:
Serine protease structure has a triad of histidine, serine, and aspartic acid that are joined with the hydrogen bonds. Aspartic protease has a structure which includes the two aspartic acid residues which attack the peptide bond.
Serine protease catalyzes the hydrolysis of the peptide bonds with the the help of two tetrahedral intermediates, whereas the aspartic protease abstracts the proton from water molecule it results in nucleophilic attack on the carbonyl atom of carbon resulting in breakage of peptide bond.
Suppose there was NO meiotic recombination but maternal and paternal chromsomes still assorted randomly during meiosis. How many different kids would be possible from two parents?
Answer:
8,324,608 chromosome combinations
Explanation:
During meiosis, chromosomes separate independently so that only one chromosome came from the father and the other homologous chromosome came from the mother. This process of independent assortment produces a huge amount of possible combinations in the diploid zygote cell. In humans, the haploid number of chromosomes is n = 23, thereby there are 2²³ = 8,324,608 chromosome combinations. Thus, the independent assortment of chromosomes during meiosis is a key factor that contributes to genetic variation in the offspring.

Living things need to maintain their internal environment . This is known as homeostasis What role does homeostasis play in controlling the rate of chemical reactions in our bodies ?
Answer:
Homeostasis is the tendency to resist change in order to maintain a stable, relatively constant internal environment. Homeostasis typically involves negative feedback loops that counteract changes of various properties from their target values, known as set points.

Choose the best explanation of a partial solar eclipse?
A. The earth only partially covers the sun during the eclipse
B. The moons phase is full and blocks out most but not all of the sun
C. During a new moon phase there is usually a partial but not total eclipse
D. The moon only partially covers the sun during the eclipse
Answer:
The best explanation for a partial solar eclipse is that moon only partially covers the sun during the eclipse (option D).
Explanation:
A solar eclipse occurs when the moon stands between the sun and the earth, which happens when the moon is near the plane of the ecliptic, that is, the point where the orbits of the earth and the sun intersect.
A partial solar eclipse occurs when the moon partially covers the sun, which depends on the observer's point of view on the earth and his geographical location.
The other options are not correct because:
A. If the earth stands between the sun and the moon, lunar eclipses occur.
B and C. During a solar eclipse it is not possible to see lunar phases, which occur when the sun's rays are reflected off the satellite.
