The skin is protected by the action of cells that arise from bone marrow and migrate to the epidermis. Which cells serve this function?

Answers

Answer:

Langerhan's cells

Explanation:

The Langerhan's cells arise from the bone marrow and migrate to the epidermis. The Langerhan's cells are the body's first line of defense and play a significant role in antigen presentation. They need special stains to be visualized and are primarily found in the stratum spinosum. These are the mesenchymal origin obtained from CD34 positive stem cells of bone marrow and are part of the mononuclear phagocytic system.

In mice, apricot eyes is recessive to black eyes. Tail length is governed by another gene, linked to the eye color gene. Long tails is dominant to short tails. To determine the distance between the two genes, a double heterozygote is mated in a testcross and the classes of progeny produced were as follows:
Apricot eyes, Long tails 33
Apricot eyes, Short tails 20
Black eyes, Long tails 17
Black eyes, Short tails 30
Determine whether the heterozygous parent is in the cis or trans arrangement.
a. Cis
b. Trans

Answers

Answer:

trans

Explanation:

From the given information:

The study observes the genes present in mice for eye color and tail length. Since both genes are linked, it implies that they exist in the same chromosomes.

Black eyes is dominant over apricot eyes

Let Black eye be B and apricot eyes be b

Long tail is dominant over short tail

Let long tail be L and short tail be l

If double heterozygote(homoozygous-recessive) engage in the testcross

Then:

From the result given:

The parental combinations are:

Apricot eyes, Longtail  (bL / bl) =  33

Black eyes, Short tails (Bl / bl) = 30

The recombinant genes are:

Black eyes, Long tails (BL / bl) =  17

Apricot eyes, Short tails (bl / bl) = 20

The recombination frequency relates to the distance between the two genes which can be computed as:

= (20+17)/100

= 37%

Thus; the heterozygous parent is in trans arrangement.

If all 15 presynaptic neurons stimulate the post-synaptic neuron at the same time, will an action potential be produced?

Answers

Answer:

Yes

Explanation:

If all 15 presynaptic neurons stimulate the post-synaptic neuron at the same time, the action potential will be produced. In a chemical synapse, an action potential in the presynaptic neuron is responsible for the release of a chemical messenger known as neurotransmitter. After this, the neurotransmitter diffuses across the synapse and binds to the postsynaptic cell so we can say that potential can be produced.

Normal diploid somatic cells of the mosquito Culex pipiens contain six chromosomes. The G1 nucleus of a mosquito cell contains 3.0 x 10^-12 grams of DNA. How much nuclear DNA would be expected in metaphase I of meiosis?
a. 6.0 x 10^-12 g.
b. 1.5 x 10^-12 g.
c. 12 x 10^-12 g.
d. 3.0 x 10^-12 g.
e. 0.75 x 10^-12 g.

Answers

Answer:

a. 6.0 x 10^-12 g.

Explanation:

The interphase is the previous step before the cell divission occurs. The interphase is formed of the G1, S, and G2 stages.  

• During the G1 stage, it occurs a high intense biochemical activity. The cell duplicates its size, and the organelles and other molecules and cytoplasmatic structures duplicate too. Some structures, such as microtubules and actin filaments, are synthesized from zero. The endoplasmic reticulum increases in size and produces a membrane for the Golgi apparatus and vacuoles, lysosomes, and vesicles. During this stage, the pair of centrioles separate, and each centriole duplicates. Mitochondria and chloroplasts also replicate.  

During the S stage occurs the DNI replication process. It also occurs the synthesis of histones and other associated proteins. This is the only stage where the DNI molecule is replicated.

• G2 stage is the final one before the cellular division. Here begins the slow process of DNI condensation. Duplication of centrioles completes. Structures such as spindle fibers are assembled.  

Through the process of Meiosis, a diploid germ cell (2n) divides and originates four daughter cells with a haploid chromosome number (n). Each daughter cell has half of the chromosomes of the original one. Meiosis is completed in two phases. During the first phase, and after replication, occurs the chromosome´s reduction division. During the second phase, the cell suffers a new, not reductive division.

1. In the first phase, Meiosis I:  

Prophase I: Chromosomes condensate and became visible. Occurs crossing-over between homologous chromosomes. Crossin-over makes the daughter cells to be genetically different from the original one.  Metaphase I: The pairs of homologous chromosomes randomly align in the equatorial plane.  Anaphase I: occurs the independent separation of homologous chromosomes that migrate to opposite poles of the cell. This separation generates different chromosomal combinations in the daughter cells.  Telophase I: Each of the homologous pairs chromosomes is already in the corresponding poles, and the nuclear membrane forms again in each pole.  

2. In the second phase, Meiosis II:  

Prophase II: Chromosomes condensate again and become visible.  Metaphase II: Chromosomes join the spindle apparatus and migrate to the equatorial plane, where they randomly line up. Sister chromatids are holden together until they reach the Anaphase.  Anaphase II: Centromeres divide, chromatids get separated, and each of them goes forward an opposite cellular pole.  Telophase II: Once in the poles, the chromosomes became lax again, and cytokinesis occurs.  

In the exposed example, DNI in the G1 nucleus of a mosquito cell still has not suffered replication (3.0 x 10^-12 grams). The replication process occurs during the S stage, which follows the G1 stage. After the S stage, the cell has 6.0 x 10^-12 g of DNI.

During meiosis, the reduction in chromosomes number occurs in anaphase where homologous chromosomes migrate to different poles. But during metaphase I, the cell still has 6.0 x 10^-12 g of DNI.

Innate talents are those talents that are present in the organism from birth, They are not learned or observed from outside. These abilities are only enhanced as we grow up. They are already present in the body.

They are the natural, talents that with we grow up. Innate talents are also called natural skills. They are genetically present in our bodies. Some people are born with natural potential and skills. But without hard work and practice, these skills would not work.

Abilities are the things that are used by the organism to perform activities. Every organism has some abilities.

Discuss the sensory neurons for vision. What are the two
types of sensory neurons for vision? Where are they located?
What are their functions in the eye? What path does visual
input take AFTER reaching the sensory neurons (be specific,
outlining the entire path to the destination point of the brain)?

Answers

Answer:

Olfactory sensory neurons (OSN).

Explanation:

Olfactory sensory neurons (OSN) are the sensory neurons that is responsible for vision. Photoreceptors and olfactory sensory neurons (OSN) are the two types of sensory neurons for vision. Both olfactory sensory neurons (OSN) and photoreceptors is responsible for the receiving of photons and enable us to see things. The right half of the visual field will travel in the left optic tract, while on the other hand, the stimuli from the left half of the visual field will pass through the right optic tract.

Answer: The two types of sensory neurones are the CONES and RODS. Their functions are better outlined below

Explanation:

The CONES and RODS are the sensory neurones ( photoreceptors) of the eye which are located in the retina.

The RODS: They are extremely sensitive and can detect light of very low intensity. They also perceive light in black and white. They, therefore, play an important role in dim light.

The CONES: They function in bright light and are responsible for colour vision.

The path visual input take AFTER reaching the sensory neurons is as follows:

--> the rods and cones are stimulated

--> A pattern of electrical impulses is sent to the brain through the optic nerve which interprets it, drawing on past experience.

The brain tells us that the object is upright and gives us it's real size and distance from the eye. We, therefore, see the object as it actually is, and not as the image formed on the retina.

Solve the equation of mava=mbvb max5.0ml=5.2mlx0.10m

Answers

Answer:

0.104M

Explanation:

The following equation is given in this question:

mava=mbvb

Where;

ma = molarity of acid (M)

mb = molarity of base (M)

va = volume of acid (ml)

vb = volume of base (ml)

According to this inputted values;

max5.0ml=5.2mlx0.10m

ma = unknown molarity of acid

mb = 0.10M

va = 5.0ml

vb = 5.2ml

Hence, ma x 5.0ml = 5.2ml x 0.10m

5ma = 0.52

ma = 0.52 ÷ 5

ma = 0.104M
