Gregor Mendel, through his work on pea plants, discovered the fundamental laws of inheritance. He deduced that genes come in pairs and are inherited as distinct units, one from each parent. Mendel tracked the segregation of parental genes and their appearance in the offspring as dominant or recessive traits.
Where is the diaphragm located in relation to the lungs?
a) inferior
b) medial
c) superior
{ Relating to a crash course video called: Respiratory System Crash Course}
[any information would be very much appreciated! thank you :D]
Answer:
A. Inferior
Explanation:
If you're not familiar with anatomical terms, a quick summarization would be:
-Inferior: below
-Superior: above
-Medial: towards the midline of the body
Upon googling a picture for the diaphragm and lungs, you will see that the diaphragm is a muscle situated directly below the lungs. The phrase "located in relation to" is asking you specifically "when compared to". Therefore, since the diaphragm is located below the lungs, the answer would be inferior.
I hope this answer and explanation helped you understand this topic a little bit more!
The diaphragm is located in inferior to lungs.
What is diaphragm ?
In mammals, the diaphragm is a dome-shaped, muscular and membrane tissue that divides the thoracic and abdominal compartments.
It is the primary respiratory muscle.
The diaphragm gets contract and flatten up during we inhale, while the chest cavity expands.
Vacuum is created due to contraction, which pulls air into the lungs.
Exhalation relaxes the diaphragm and causes it to return to its domelike shape, pushing air out of the lungs.
So we can conclude that the diaphragm is the muscle that connects the chest cavity to the abdomen and it is the primary respiratory muscle, when one breathes in, the diaphragm muscle contracts, causing the lungs to expand and vice versa, and most importantly it located inferior to lungs.

A lipoprotein particle functions to ________. dissolve polar lipids for excretion transport nonpolar lipid to body cells metabolize lipids into new substances dissolve polar lipids in urine store lipids in the tissues
Answer:
The correct answer is ''transport nonpolar lipid to body cells''
Explanation:
Lipoproteins are macromolecules whose function is to package insoluble lipids in the aqueous medium of plasma and transport them from the intestine and liver to peripheral tissues. They transport all the lipids that circulate in the plasma: free and esterified cholesterol, triglycerides and phospholipids. Plasma lipoproteins constitute a polydisperse and heterogeneous system of particles of almost spherical morphology, which have a hydrophobic nucleus or core formed by nonpolar lipids, that is, esterified cholesterol and triglycerides, and by a hydrophilic surface layer containing unesterified cholesterol, phospholipids and specific proteins called apoproteins.

Steps of Translation
Using the following word bank: anticodons, codons, mRNA, RNA; fill in the steps of translation.
The ribosome binds to a strand of _____
This nucleic acid has
three-nucleotide codes called ______
The three-letter codes are complementary
to ________
on ________
molecules. Each of these
molecules brings with it an amino acid, which will become part of the growing polypeptide.
Answer:
The correct answer is - mRNA, codons, anticodons, RNA.
Explanation:
During the translation process of protein synthesis, the mRNA strand is attached with the ribosome in order to translate the three-letter nucleotide sequence that is called codons or triplet code into specific amino acids.
These three-letter codes are complementary to the anticodons on the RNA (tRNA) molecules. These nucleic acid molecules with ribosomes bring with them an amino acid to make a polypeptide chain.

If a motion is not seconded, what happens to the motion?
Answer:
After a motion is proposed, if the motion requires a second and none is immediately offered, the chair of the body will usually ask, "Is there a second?" If no second is obtained within a few moments of proposing the motion, then the motion is not considered by the assembly, and is treated as though it was never offered. Such a motion may be introduced again at any later time.

In the trp operon, tryptophan serves as a(n) ___________________, binding to the repressor and causing it to block to attachment of RNA polymerase.
a. operator
b. inducer
c. repressor
d. corepressor
e. gene
In the trp operon, tryptophan acts as a corepressor, binding to the repressor and inducing it to stop to attachment of RNA polymerase. Therefore, option D is correct.
What is trp operon?The trp operon is a group of genes in bacteria that are involved in the biosynthesis of the amino acid tryptophan. The operon is composed of five structural genes, trpE, trpD, trpC, trpB, and trpA. These genes code for the enzymes involved in tryptophan biosynthesis.
In the trp operon, the presence of tryptophan serves as a corepressor. The tryptophan molecule binds to the trp repressor protein, causing a conformational change that allows it to bind to the operator region of the operon.
This blocks the attachment of RNA polymerase to the promoter, preventing transcription of the genes involved in tryptophan biosynthesis. Thus, option D is correct.

It has been proposed that the presence of black markings on the throat of kung fu geckos is coded by a dominant allele (B) and that the absence of such markings is coded by a recessive allele (b). To test this idea, heterozygous individuals are crossed (Bb x Bb) producing 500 offspring of which 350 have black markings and 150 don’t have black markings. Based on a punnett square, the expected phenotypic ratio for black markings to no black markings is 3:1.
Required:
Write down the correct statistical approach to test if the data is consistent with the expected 3:1 ratio.
Answer:
See the answer below
Explanation:
The correct statistical approach to test if the data is consistent with the expected 3:1 ratio would be the Chi square.
Chi-square = [tex]\frac{(O - E)^2}{E}[/tex] where O = observed frequency and E = Expected frequency. In this case:
Phenotype O E Chi square
Blacks 350 3/4 x 500 = 375 [tex]\frac{(350-375)^2}{375}[/tex] = 1.67Non blacks 150 1/4 x 500 = 125 [tex]\frac{(150-125)^2}{125}[/tex] = 5Total Chi square = 1.67 + 5 = 6.67
Degree of freedom = 1
Tabulated Chi square = 3.841
Since the calculated Chi-square is more than the tabulated value, the null hypothesis is rejected and we conclude that the data is not consistent with the expected 3:1 ratio.

25. A cell has 20 amino acids. How many molecules of tRNA are in the cell?
1. Four
2. Three
3. More than 20
4. At least twenty
5. Fifteen
6. I do not know.
Answer:
I think no 3 will be the answer.
In cell one amino acid can bind with two or three different tRNA during protein synthesis in the translation process, hence 3 option is correct more than 20 molecules are found.
What is tRNA?Because they can read nucleic acid words (like mRNA codons) and transmit the relevant messages, tRNA molecules serve as translators of amino acids. for each of the 20 amino acids.
There is a tRNA some amino acids bind to 2 or 3 different tRNAs, so cells may contain as many as 32 different tRNAs. Possibility of more than one tRNA and more than one anticodon for an amino acid, there is often only one aminoacyl tRNA synthetase for each amino acid.
Enzymes known as transfer RNA (tRNA) synthetases are responsible for joining a particular amino acid to its associated tRNA in order to produce proteins at the ribosome.
Therefore one amino acid can bind with two different tRNA in a cell during translation, hence option 3 is correct.

g The dominant food chain in a kelp forest ecosystem is made up of the three species below, listed with their trophic levels. If sharks enter a kelp forest ecosystem and begin feeding on sea otters, they would have a positive indirect effect on which species
Answer:
Crustaceans, sea urchins, mollusks and fish.
Explanation:
The positive effect occurs on crustaceans, sea urchins, mollusks and fish if the shark feeds on sea otter because sea otter feeds on crustaceans, sea urchins, mollusks and fish. Decrease occur in the population of sea otter due to introduction of shark in the ecosystem which indirectly increases the population of crustaceans, sea urchins, mollusks and fish. So we can say that a positive indirect effect occurs on crustaceans, sea urchins, mollusks and fish due to shark.
