Describe the four major steps of digestion, and discuss the organs involved in each.
nouth, oesophagus, stomach, duodenum, pancreas, ileum,colon, rectum,anus.
Answer:
Ingestion is when food comes into the body through the mouth and down the esophagus. Digestion begins with chemically with enzymes in saliva, and mechanically with the teeth, and continues when food (as a bolus) enters the stomach to be dissolved by acid and pepsin. Food (chyme) then goes into the small intestine where nutrients are absorbed through the villi. Waste is then eliminated through the large intestine, rectum, and anus.

A nerve cell consists of a cell body or soma, a main fiber (axon) and many small branches (dendrites).
What is a neuron?A neuron or nerve cell forms the basic unit of brain and nervous system.These cells receive stimulus from the external world, relay the information to brain and help to generate a response.The neurons communicate with each other via special connections called synapses where they release neurotransmitter.A typical neuron consists of a cell body (soma), dendrites (brings information), and a single axon (send information away from neurons).The dendrites and axon branch out from the cell body.Cell body contains nucleus and specialized organelles.At the tip of axon are axon terminals where neurotransmitters are released to transmit signal across the synapse to other cell.Learn more about nerve cell here:

The density of the solid is 0.5. See the explanation for this below.
What is density?The measurement of how densely a substance is packed together is defined or denoted as density.
It is expressed as mass per unit volume.
Density (abbreviated D or ρ) is a mathematical concept.
ρ=m/V, where
ρ is the density, m is the object's mass, and V is the object's volume.Given the above, what is the density of the solid?From the above information:
ρ = 25/50ρ
ρ= 0.5
Why do you need to know the density of a solid?One of an object's most significant and practicable physical characteristics is density.
Densities are frequently used to distinguish between pure materials as well as to describe and infer the composition of various types of mixes.

organism that must get energy from their environment are classified as?
Answer:
Heterotroph
Explanation:
Hi, According to what I understand, the term is heterotroph, not hetrotrop [Tropism is concerned with how organisms react to a certain stimulus]
The word "heterotrophy" refers to organisms that do not synthesis their food or carbohydrates in the presence of photosynthetic pigment using CO2, water, or solar energy. With the exception of Euglena, they cannot synthesis their food or carbohydrates (it is unicellular and contains photosynthetic pigment). Carnivores, herbivores, etc. are heterotrophs.
The cichlid is a colorful fish found in freshwater lakes. There are over a thousand species of cichlid fish today. If a species of cichlid became extinct, the niche the fish filled within the ecosystem would be left open. Explain how an available niche after extinction can lead to speciation.
The niche available after extinction can lead to speciation because there would be an imbalance, making resources formerly occupied by extinct fishes vacant, providing the emergence of new species to take the place of the extinct species.
When does speciation occur?Speciation can be understood as processes that lead to the formation of new species. They occur due to differences in the genome of different populations of the same species that caused reproductive isolation and, consequently, the appearance of two different species.
With this information, we can conclude that Speciation is the process of formation of new species from lineage separation events from preexisting species.

During the process of nerve conduction, a person experiences an increase in synaptic transmissions. Which of the following is a likely contributor to this?
An increase in alcohol consumption.
The body adjusting to a person taking a meditation class.
Doubling the amount of water a person drinks daily.
Drinking caffeinated beverages several times a day.
An increase in alcohol consumption
Alcohol can boost GABA activity in the brain in one of two ways: either by acting on the presynaptic cell, which increases GABA release, or. It can influence the postsynaptic (i.e., signal-receiving) neuron, promoting the GABAA receptor's activation.
The brain circuits that regulate motivational processes, such as arousal, reward, and stress, are altered by chronic alcohol consumption. These modifications impact systems that use dopamine, opioid peptides, -aminobutyric acid, glutamate, and serotonin as signaling molecules as well as systems that control the brain's stress response. Frequent episodes of intoxication, obsession with alcohol, use of alcohol in spite of negative effects, and a need to seek out and use alcohol are all signs of alcoholism developing.

If the DNA sequence is CCAATTGA, what is the compliment?
GGTTAACT is the complement of DNA sequence CCAATTGA.
What is a complement sequence of DNA?A sequence of bases in a nucleic acid called a complementary sequence can be used to match base pairs to create a double-stranded structure. For instance, G-T-A-C is the complementary sequence to C-A-T-G, where each letter represents a different DNA nucleotide.
Every DNA sequence has a counterpart sequence running in parallel since DNA has two strands. Adenine (A) is always coupled with Thymine (T) in the complementary sequence, while Cytosine (C) is always paired with Guanine (G).
Natural complementary DNA plays a crucial role in the production of new DNA copies and has emerged as a key experimental tool. The two strands of DNA are unraveled from one another during replication. Each strand is replicated twice, one by a DNA polymerase molecule that runs the length of each strand.

AP Biology - If 72 out of 200 individuals....(pic is attached) - worth 25 points!
Answer:
A.) 48%
Explanation:
AA = dominant genotype
Aa = heterozygous genotype
aa = recessive genotype
Hardy-Weinberg Equations:
p² + 2pq + q² = 1 p + q = 1
In this equation, In this equation,
-----> p² = frequency of "AA" -----> p = frequency of "A"
-----> 2pq = frequency of "Aa" -----> q = frequency of "a"
-----> q² = frequency of "aa"
(Step 1)
Determine the frequency of the recessive allele ("a").
72 / 200 = 0.36 recessive phenotype
The only way to have the recessive phenotype is to have the recessive genotype, aa. Therefore, q² = 0.36.
If q² = 0.36, then q = 0.6 (take the square root).
(Step 2)
Determine the frequency of the dominant allele ("A").
p + q = 1
p + 0.6 = 1
p = 0.4
(Step 3)
Determine the frequency of the heterozygous genotype ("Aa").
If -----> p = 0.4 and q = 0.6
Then -------> 2pq = 2(0.4)(0.6) = 0.48
0.48 x 100% = 48% Aa

What does this graph tell you about the concentration of salt inside the cell?
The concentration of salt inside the cell was lower than the concentration of salt in the salt water, since the cell got much smaller in size due to water outward movement.
What is osmosis?Osmosis is the movement of water molecules through a semi-permeable membrane from regions of low solute concentration to regions of high solute concentration.
If salt concentration is higher inside the cell than outside, water will move into the cells. However, if the salt concentration outside the cell is higher, water will move out of the cells.
The cell became smaller, indicating that water moved out of the cell.
Thus, the salt concentration in the cell was lower inside the cell.
