Genes, Chromosomes, and DNA Quick Check
If one half of a DNA molecule has 8 thymine bases, what else is also true about the DNA molecule? ( point)
There will be 16 total bases.
There will be 32 total bases.
There will be 8 adenine bases.
There will be 8 cytosine bases.

Answers

Answer 1

Answer:

There will be 8 adenine bases.

Explanation:

There are total of 4 nitrogenous bases present in a DNA that includes Adenine, Guanine, Thymine, and Cytosine. These nitrogenous bases form complementary base pair in which, adenine form two hydrogen bonds with thymine and cytosine form three hydrogen bond with guanine.

So, if there are 8 thymine bases in a DNA (irrespective of half or full) then there will be 8 adenine bases, forming two hydrogen bond with each other.

Hence, the correct answer is "There will be 8 adenine bases."

Outside the lining of the alveolus is blood, which is at a gauge pressure of 5 mmHg, while air is contained inside the alveolus. What is the absolute pressure inside the alveolus

Answers

Answer:

765 mmHg

Explanation:

The gauge pressure = 5 mmHg

To get the absolute pressure we use the relationship

[tex]P_{ab}= P_{g}+ P_{atm}[/tex]

where [tex]P_{ab}[/tex] is the absolute pressure = ?

[tex]P_{g}[/tex] is the gauge pressure = 5 mmHg

[tex]P_{atm}[/tex] = atmospheric pressure = 760 mmHg

substituting, we have

[tex]P_{ab}[/tex] = 5 mmHg + 760 mmHg = 765 mmHg

DIHYBRID CROSSES
In all of the examples we have only been concerned with one trait. It is possible, however, to track the inheritance of more than one trait at a time. When one is investigating the inheritance of two traits at once the cross is called a dihybrid cross. Strictly speaking, a dihybrid cross is one between two individuals that are heterozygous for two traits, meaning that they are hybrids in two senses. For example, in humans eye color is determined by multiple factors, but if we compare only blue eyes to brown eyes, brown is dominant (R) and blue acts as a recessive allele (r). If a man heterozygous for both eye color and bent little finger has a child with a woman who also heterozygous for both traits, this would be a dihybrid cross. Which is/are possible genotypes for a person with bent little finger and blue eyes?
1. bbrr
2. BBRR
3. BBrr
4. Bbrr
Referring to the previous question, which is/are possible genotypes for a person with straight little finger and blue eyes?
1. bbrr
2. BbRr
3. Bbrr
4. bbRr

Answers

Answer:

Question 1: bbrr

Question 2: bbRr

Explanation:

To address the first question, the possible genotype for someone with bent little finger and blue eyes would be bbrr.

Since brown eye (B) is dominant over blue eyes (b), in order for the blue eye color to be expressed, it has to be in bb condition. The only option with bb genotype is option 1.  

For the second question, the possible genotype for a person with a straight little finger and blue eyes would be bbRr.

Blue eye genotype is bb as explained in the first question while straight little finger would be Rr since the bent little finger has been represented by the genotype rr in the first question.

c. Lightning strikes a tree and begins a fire that clears the land.
d. Ticks infesting moose weaken the moose's health and reproductive success.
e. Frigid temperatures flow into the area, causing hypothermia and death.

Answers

Answer: Option B and C.

Heavy and continuous rains flood the land, submerging habitats.

c. Lightning strikes a tree and begins a fire that clears the land.

Explanation:

Heavy and continuous rains flood the land, submerging habitats.

Lightning strikes a tree and begins a fire that clears the land.

The above are example of density independent abiotic factors because rainfall and lightning affect the population size of the environment by decreasing it's population sizes.

Abiotic factors are the non living part of the environment and they include rain fail, temperature,lightning, humidity e.t.c.

Density independent abiotic factors are factors that decrease or increase the population size of the ecosystem.

Therefore, Heavy and continuous rains flood the land, submerging habitats.

cLightning strikes a tree and begins a fire that clears the land are density independent factor because they decrease the population size.

The scenarios that describe an abiotic factor that is density independent are ; ( B and C )

Heavy and continuous  rains flood the land, submerging habitats ( B )Lightning strikes a tree and begins a fire that clears the land ( C )

Abiotic factors are Nonliving components of an ecosystem that has a significant effect on the ecosystem such as ; Rain, rocks, Temperature and humidity. Density Independent factors are factors in an ecosystem that can cause the decrease or increase of the population size of an ecosystem.

Heavy and continuous rainfall is an abiotic factor that has the ability to decrease the population of an ecosystem by submerging organisms habitats.

Lightning striking a tree and setting it ablaze which clears the land also reduces the population of the ecosystem because the fire will lead to loss of habitats and death of some organisms .

Hence we can conclude that The scenarios that describe an abiotic factor that is density independent are Heavy and continuous  rains flood the land, submerging habitats and Lightning strikes a tree and begins a fire that clears the land .

Acidification of the stomach uses all of the following types of transport EXCEPT: A. channels. B. pumps. C. antiporters. AND. symporters. E. All of these are used by parietal cells.

Answers

Answer: Option E.

All of these are used by parietal cells.

Explanation:

Parietal cells are found in the stomach and they produced gastric acid(Hcl)..

HCl is produced when water mixed with carbondioxide in the parietal cell to produced carbonic acid which is catalyses by carbonic anhydrase. The carbonic acid then dissociates into hydrogen ion and carbonate ion.

Parietal cell produce HCl due to histamine (via H2 receptors), acetylcholine (M3 receptors) and gastrin (gastrin receptors).

Therefore it uses channels, pumps, antiporter.

In the DNA isolation process, cells are mixed with sodium chloride (i.e. NaCl) because the sodium (Na ) neutralizes the negative charge of DNA.

a. True
b. False

Answers

Answer:

this is true it neutralise easily

It is true that in the DNA isolation process, cells are mixed with sodium chloride (i.e. NaCl) because the sodium (Na ) neutralizes the negative charge of DNA.

What is DNA isolation?

DNA extraction is a method of separating DNA from cell membranes, proteins, and other cellular components using physical and/or chemical methods from a sample. In 1869, Friedrich Miescher isolated DNA for the first time.

The ability to extract DNA is critical for studying the genetic causes of disease and developing diagnostics and drugs.

It is also required for forensic science, genome sequencing, detecting bacteria and viruses in the environment, and determining paternity.

Because sodium (Na+) neutralizes the negative charge of DNA, cells are mixed with sodium chloride (i.e. NaCl) during the DNA isolation process. It makes homogenization easier.

Thus, the given statement is true.

If an experimenter wants to use the GFP method but needs to detect the presence or absence of several proteins at the same time, he can take advantage of mutational variants of GFP that emit what light?

Answers

Answer:

different colors

Explanation:

The green fluorescent protein (GFP) is a type of protein widely used in molecular biology laboratories because this protein can be used to detect the expression of proteins and to identify cellular structures. This protein displays green fluorescence when it is excited by blue light and, in the last years, many variants of the GFP protein have been developed. The altered GFP proteins react to distinct wavelengths of light, thereby emitting light to different colors. The mutants forms of the GFP protein are produced by genome engineering techniques that generate modifications capable of altering the folding of the normal GFP protein.

The ion composition of perilymph is like that of interstitial fluid; high sodium and low potassium levels. If someone ruptured the vestibular membrane, the membrane between the vestibular duct (Scala vestibuli) and the cochlear duct (Scala media), what would be the effect of such a rupture on the concentration of potassium in the endolymph in the cochlear duct

Answers

Answer:

The concentration of potassium will decrease

Explanation:

The cochlear ducts are composed of two distict types of fluids: 1-perilymph, rich in sodium (140 mM) and low in potassium (5 mM), and 2- endolymph, rich in potassium (1 mM) and low in sodium (150 mM). The perilymph fluid has a similar composition to the rest of the extracellular fluids, while endolymph present a unique ion composition that is not found in other fluids of the body. It is believed that the cochlea can regulate potassium flow without using energy (i.e.,  without use ATP), since potassium enters into the cells through passive pathways, while this ion ion leaves the cells by an active mechanism.
