Answer:

Mechanical digestion is a purely physical process that does not change the chemical nature of the food. Instead, it makes the food smaller to increase both surface area and mobility. It includes mastication, or chewing, as well as tongue movements that help break food into smaller bits and mix food with saliva.

If I had a section of DNA that contains 350 nucleotides and the A's and Ts made up 200 of
those nucleotides, how many As
Gs
Cs
and Ts
do I have?(.5 points each response)

Answers

Answer:

100 A

100 T

75   C

75   G

Explanation:

there will be an equal amount of thymine and adenine since they bind together so, 200/2 = 100 each

now there is 150 nucleotides left

guanine binds to cytosine so they also have an equal amount, so 150/2=75

Given, the number of nucleotides in the section of DNA = 350Nucleotides in DNA are of four types - Adenine (A), Guanine (G), Thymine (T), Cytosine (C).Adenine pairs with Thymine while Guanine pairs with Cytosine.Given, there are 200 nucleotides made by Adenine and Thymine.We know, Adenine pairs with Thymine so they will have equal number of nucleotides.So, the number of Adenine = the number of Thymine = 200 ÷ 2 = 100Number of nucleotides made by Guanine and Cytosine = 350 - 200 = 150We know, Guanine pairs with Cytosine so they will have equal number of nucleotides.Therefore, number of Guanine = number of Cytosine = 150 ÷ 2 = 75

Answer:

As = 100

Ts = 100

Gs = 75

Cs = 75

A frameshift mutation that results in the insertion of three nucleotides is often less deleterious than a mutation that results in the insertion of one nucleotide. Why?

Answers

A frame shift mutation that results in the insertion of 3 nucleotides doesn’t reading frame of the downstream codons and proteins they will be made into.

A mutation that inserts a single nucleotide ultimately will change the reading frame and all of the codons (3 nucleotides) downstream of that insertion will make a different protein than they were suppose to or a stop codon could be made which will completely stop that protein from being made.

Example: AUG UAU ACU CAC
The example above will encode for the following proteins.

met, Tyr, Thr, His

3 nucleotide insertion in this example could be:

AUG UAU AAU ACU CAC

met, Tyr, Asn, Thr, His

1 nucleotide insertion mutation:

Example: AUG UAA U ACU CAC

Met, stop codon

Nucleotides after the A insertion are not made into proteins.

what type of ions carry the impulse across the synapse from one neuron to the next ?

Answers

It's the sodium ion.

When a neural impulse is fired in both neurons, it is always cause by an excited electron in one neuron moving to the other neuron to destabilize the balance of ions trying to keep them at equilibrium. This action either depolarizes or hyper-polarizes the membrane. If it does, then sodium ions--the key deficient ones--can flow into that region of low charge and maintain that state of low charge, keeping the cell membrane stable.

What are MAD (mitotic arrest deficient) proteins and when are they important in the cell cycle?

Answers

Answer:

The mitotic arrest deficient protein MAD2B (MAD2L2) is a member of a MAD family of proteins and shows 48% similarity to MAD2 (MAD2L1) [1], [2]. Both MAD2 and MAD2B can bind to the anaphase promoting complex or cyclosome (APC/C), which is a downstream target of the mitotic spindle checkpoint.

MAD (mitotic arrest deficient) are proteins related to spindle cell cycle checkpoint and it is important since they prevent the segregation of sister chromatids until all have bound to the spindle.

The cell cycle ensures the duplication of the genome and its distribution in daughter cells by passing through a coordinated and regulated sequence of events.

A series of checkpoints guarantee the orderly progression of the phases of cell division and the correct distribution of the duplicated genetic material in the daughter cells.

The checkpoints during mitosis are:

At the end of stage G1 and before S.

Before anaphase in mitosis.

DNA damage checkpoints in G1, S or G2.

The checkpoint before anaphase in mitosis guarantees the separation of chromosomes, and operates by activating the Mad2 protein that prevents the degradation of segurin, until the conditions are appropriate.

That is, the Mad2 protein prevents the segregation of sister chromatids until they have all bound to the spindle.

Therefore, we can conclude that MAD (mitotic arrest deficient) are proteins related to spindle cell cycle checkpoint and it is important since they prevent the segregation of sister chromatids until all have bound to the spindle.

mendel’s law of segregation states that the two alleles for each gene separate during gamete formation. during which stage of meiosis do the alleles separate?

Answers

anaphase (the chromatids pull apart to opposite ends)

The stage of meiosis at which the alleles separate is anaphase. The correct option is B.

What is meiosis?

Meiosis is a type of cell division of germ cells that produces gametes such as sperm or egg cells in reproducing organisms through gametes.

It entails two rounds of division, resulting in four cells with only one copy of each chromosome.

Meiosis 1 separates a pair of homologous chromosomes and converts a diploid cell to a haploid cell. It is divided into four stages: prophase, metaphase, anaphase, and telophase.

The homologues are pulled apart and moved to opposite ends of the cell during anaphase I.

The sister chromatids of each chromosome, on the other hand, remain attached to one another and do not separate. Finally, in telophase I, the chromosomes arrive at the cell's opposite poles.

Thus, the correct option is B.

Imagine for a moment that a large artery formed two branches carrying blood to two different organs. Branch 1 has a radius of 0.5 cm and Branch 2 has a radius of 1.0 cm. If the blood flow rate in Branch 1 is 2ml/min, what do you expect the blood flow rate of Branch 2 to be

Answers

The flow rate through Branch 2 is 8·√2 ml/min

Reasons:

Radius of Branch 1 = 0.5 cm

Radius of Branch 2 = 1.0 cm

Flow rate, Q = Velocity, V × Area, A

The area of the Branch 1 = π × 0.5² = 0.25·π

We have;

[tex]\dfrac{v_1^2}{r_1} = \dfrac{v_2^2}{r_2}[/tex]

Which gives;

[tex]v_2 = \mathbf{\sqrt{\dfrac{v_1^2}{r_1} \times r_2}}[/tex]

[tex]The \ velocity \ of \ Branch 1 , \ v_1 = \dfrac{2}{\pi \times 0.5^2} = \dfrac{8}{\pi}[/tex]

Therefore;

[tex]v_2 = \sqrt{\dfrac{\left(\dfrac{8}{\pi} \right) ^2}{0.5} \times1} = 8 \cdot\dfrac{\sqrt{2} }{\pi}[/tex]

[tex]The \ flow \ rate, \ Q_2 = 8 \cdot\dfrac{\sqrt{2} }{\pi} \times \pi \times 1^2 = 8 \times \sqrt{2}[/tex]

Answer:

b. Ovulation is the release of a mature ovum, which occurs once each month.

Explanation:is correct. post protected

Ovulation is the release of a mature ovum, which occurs once each month. The correct option is B.

What is ovulation?

The process of an egg being released from the ovary is called ovulation. The egg is released and travels down the fallopian tube, where it remains for 12 to 24 hours before being fertilised.

Although ovulation is necessary for conception, more than simply an egg is required. For instance, there needs to be a clear path to the egg. A blocked fallopian tube prevents pregnancy from happening.

Around the time of ovulation, you could notice that your cervical mucus is wetter, clearer, and more slippery. After ovulation, there is a slight increase in body temperature that you might be able to measure with a thermometer.

Thus, the correct option is B.
