High Altitude Living Quick Check
Tibetans' physiological adaptations make them less likely to suffer from pulmonary hypertension (or high blood pressure). So, the correct option is C.
What do you mean by Adaptations?
Adaptations may be defined as the evolutionary process where an organism becomes better suited to its habitat, in order to survive and reproduce in it.
Tibetans are adapted to high altitudes by producing fewer red blood cells. They have greater hypoxic and hypercapnic ventilatory responsiveness. They have large lungs, and greater lung diffusing capacity. This leads them less likely to suffer from pulmonary hypertension.
Therefore, Tibetans' physiological adaptations make them less likely to suffer from pulmonary hypertension (or high blood pressure).

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.

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.

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.

Nonvascular plants have never evolved to the size of vascular plants, most likely because they lack Select one: a. a photosynthetic mechanism. b. an efficient mode of respiration. c. an efficient system for conducting water and minerals. d. nutrient and water absorption mechanisms. e. They lack all of these choices.
Answer:
The correct answer is c. an efficient system for conducting water and minerals.
Explanation:
Non-vascular plants lack the internal tubes or vessels that carry water and minerals or nutrients through the entire plant. Most of them are found in humid or submerged places, since this type of environment allows them to absorb water through the surface of their tissues. Non-vascular plants do not grow very tall due to the lack of structures normally associated with vascular plants. Non-vascular plants lack specialized vascular tissue (xylem and phloem) for conduction and internal support of water and food. Metabolites and other nutrients are transferred between and within cells by osmosis, diffusion, and cytoplasmic flow.
2. Plants follow a reproduction pattern called alternate generations. Explain the two processes in alternate generations.
Answer:
Alternation of generations is a type of life cycle by which species alternate haploid (n) and diploid (2n) individuals.
Explanation:
Alternation of generations refers to the life cycle observed in terrestrial plants by which species alternate between haploid (i.e., organisms having a single set of chromosomes) and diploid (2n, i.e., organisms having a single set of chromosomes) generations. Plants alternate between a sporophytic stage and a haploid gametophytic stage. This alternation of generations is accompanied by the alternation between sexual reproduction, where the fusion of male and female gametes from the gametophyte generation produces a diploid zygote that develops into the sporophyte, and asexual reproduction, where spores (generated in the sporangium of the diploid sporophyte) are released and germinate into new individuals.

How many cells do you end up with in Meiosis?
A) 2
B) 1
C) 3
D) 4
Answer:
During meiosis , four daugther cells are produced
Answer:
4 cells. You end up with four cells.
Explanation:
Each daughter cell undergoes meiosis-II, producing two cells. In meiosis-II the separation of two chromatids occur so that equal number of chromatids (in fact chromosome due to duplication of genetic material) goes to each of the daughter cell.
Thus, at the end of meiosis-II, four daughter cells are formed. Each cell has half the number of chromosomes present in the diploid cell.

Answer:
At convergent plate boundaries, oceanic crust is often forced down into the mantle where it begins to melt. Magma rises into and through the other plate, solidifying into granite, the rock that makes up the continents. Thus, at convergent boundaries, continental crust is created and oceanic crust is destroyed.

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.

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.

g Name and describe two possible pathogens that could be responsible. The spinal tap reveals the presence of Gram-negative cocci in the CSF. What would be the likely diagnosis
Answer:
Explanation:
The missing information describing the status of the sick sophomore student is attached in the image below.
The first question says we should name and describe the two possible pathogens responsible for such.
The two possible pathogens are:
Virus and Bacteria.
Recall that, the College student experienced a severe headache, nausea, vomiting, neck stiffness, and fever.
These highlighted symptoms are commonly caused by meningitis which is a bacterial infection.
Surgeons, surgical tools, and scrub nurses must all be sterile when doing surgery; If any infection arises provided all crucial measures were not taking into consideration, it would harm the patient and there will be a risk of meningitis as a result of this.
SImilarly, given that In the CSF, the presence of Gram-negative cocci is shown via a spinal tap; then the likely diagnosis would be that:
The patient has suffered from Neisseria meningitis.
This is because Gram-negative cocci are the most prevalent cause of infection in persons of this age group and In the Gram stain test, it has a dark red color.
