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

Answers

Answer 1

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.

g 33. Humans are bipedal omnivores (we eat both meat and plants, and we walk upright.) What features of the skull reflect this

Answers

Answer:

Since Skull is the most complete fossil, the features of the skull that reflects Humans as bipedal omnivores are: The teeth and the foramen magnum.

Explanation:

Humans are bipedal because they can move with their two legs, and they are omnivores because of their ability to eat both meat and plants.

The teeth on a skull are the most important indicators of what an animal eats, and it even shows if an animal is a predator or prey. Humans have different sets and shapes of teeth for different purposes making them an example of heterodont dentition.

The pelvis, knee, and foot bones should be the best to tell us about how an animal moves, however, the foramen magnum which opens for the spinal cord to pass to the brain, could also show whether how the animal moved.

Which of the following requires constant agonist-antagonist muscle contractions?
Core integration
Postural development
Dynamic balance
Neuromuscular strength

Answers

Answer:

Postural development

Explanation:

The agonist muscles are sets of muscles responsible for causing joint motion, whereas antagonist muscles are muscles that directly opposite agonist muscles (i.e., antagonist muscles generate an opposing joint torque to the agonist muscles). In a given movement, agonist muscles exhibit concentric contractions while antagonist muscles show eccentric contractions in order to stabilize the joint. Postural development is achieved by concerted adjustments of dorsal muscles and ventral muscles. The dorsal muscles are activated when the body sways forward and the muscle fascicles shorten. During backward sway, these muscles lengthen, while ventral muscles are primarily activated.

Dynamic balance is the condition that requires constant agonist-antagonist muscle contractions.

The agonist-antagonist muscle contraction is the movement where one muscle contracts while the other muscle is relaxing or lengthening. The muscle contracts are agonist whereas the muscle that relaxes is the antagonist here.

Core integration: In such conditions, the constant movement of muscle contraction and relaxation does not require. It is a specific movement and increased stability of the movements.Postural development: continuous development and growth of postural muscles comprising the nervous systemDynamic balance: It would be the ability to balance in motion or changing positions. In this case, muscles require constant both agonist and antagonist contractionsNeuromuscular strength: motor commands according to the central nervous system to the ability to move in the nervous system, hence it does not require constant muscle movements.

Thus, the correct answer is - Dynamic balance.

Sickle cell anemia in the United States disproportionately affects African Americans; 1 in 700 African Americans are affected by sickle cell anemia, while only 1 in 160,000 Americans of European descent are affected. The absolute risk of a newborn African American child having sickle cell anemia is ____________%, and the relative risk compared to a newborn European American child is ____________-fold

Answers

Answer:

0.0014; 0.0044

Explanation:

The absolute risk (AR) of a disease refers to the risk of developing the disease over a given time period. In this case, the absolute risk of the newborn African American child having sickle cell anemia is equal to 1 individual with the disease over 700 individuals >> AR = 1 / 700 = 0.0014. Moreover, the Relative Risk (RR) is calculated by comparing the likelihood of the absolute risk occurring between two distinct groups. In this case, the relative risk for the newborn African American having sickle cell anemia compared to a newborn European American child can be calculated by dividing the absolute risk of the newborn European American child with the measured absolute risk of the newborn African American child >> RR = 0.0000625 / 0.0014  = 0.0044.

In a diploid cell, a FISH probe should produce ____________ signals in metaphase FISH and ____________ signals in interphase FISH.

Answers

Answer: Four, two

Explanation:

FISH (fluorescence in situ hybridization) is a technique for chromosome mapping with probes that emit fluorescence and allow the visualization, distinction and study of chromosomes of nuclei in metaphase or inferophase. In this way, any type of anomaly such as inversions, aneuploidies, duplications or microdeletions can be seen. To do this, a non-specific DNA staining is performed with DAPI (a fluorophore that marks the nucleus where DNA is present) and the fluorescence will be seen under the microscope.

When cells are in metaphase, their chromosomes are condensed in preparation for cell division. To stop them in metaphase, colchicine is used which is a microtubule depolymerizing agent responsible for separating the sister chromatids of a chromosome, thus preventing the progression of cell division and arresting the cell cycle in metaphase. Here we will see translocations, microdeletions or duplications.

Interphase FISH is used to see decondensed chromatin, which allows higher resolution in detecting small abnormalities. It is mainly used for the detection of aneuploidies or large deletions, duplications or translocations when samples are difficult to grow or are scarce, as in the case of fetal or tumor cells. It is not possible to distinguish between a normal karyotype and a karyotype showing a balanced translocation. In addition, it can be used in the analysis of solid tumors, which divide very infrequently.

During metaphase, the chromosomes are duplicated so there would be two sets of chromosomes (a total of four chromosomes). Then, there would be four signals for each probe. During interphase, the chromosomes are not dupicated. Since it is a diploid organisms, there would be two chromosomes and this will represen two signals for probe.

Explanation:

Constipation happens when the colon absorbs too much water, this can occur if the muscles in the colon are contracting slowly or poorly, causing the stool to move too slowly and lose more water. As meat need much water to digest, so they leads to problem of constipation. Hence, they should eat sufficient amount of water to cure constipation.

Constipation is common among people in western countries who eat more meat and processed food because there is no enough roughage in their bodies which prevents constipation .Fruits and vegetables like like corn etc contains lot of roughage.

The question is kind of confusing but from what I understand; missense mutations happen when an amino acid is changed to another amino acid. To find out more specifically, look at a codon chart trust me it helps so much lol (just search codon chart and go to images). missense mutations can also cause a premature stop codon so look for a changed amino acid and a stop codon when u look at the codon chart. maybe if u see the different pairs you can get a more specific answer.

You are a well-trained Cytogenetic Technologist. You work as a Genetic Counselor at a medical institution. You are meeting a nervous couple in your office, who recently found out that they are going to be first-time parents. They have come to you to discuss the chances of having a child with birth defect or genetic disorder. To ease their nerves, you greet them with a smile in your white coat, guide them to their seats, and slowly go through the options of prenatal tests available for them.
KARTOTYPE TEST METHODS
First you introduce to the parents the importance of karyotype test, by describing its domy to detect two broad categories of abnormalities in chromosomes, (1)_____and (2)_____. You provide a few examples of genetic disorders that can be caused by chromosomal abnormalities, such as (3)____and (4)____. Some parents would like to know what is the main cause of these genetic disorders. Without going into too much detail, you explain to them that chromosomal abnormalities are usually caused by (5)____in meiosis I and melosis II, when the homologous chromosomes or sister chromatids fail to separate during meiotic cell division
After the parents have decided to conduct a fetal karyotype test, you collect a small sample of chorion cells through chorionic villi sampling (CVS). Chorion is a membrane around the embryo that eventually fuses with the amnion. The chorion cells are grown in culture because chromosomes are most visible at (6)___stage of cell division. You use a technique called banding to create distinguishable landmarks on the chromosomes. There are several types of staining techniques you can use for karyotyping, some advanced techniques like FISH (fluorescent in situ hybridization) uses fluorescent probes to add colors onto different DNA sequences on the chromosome. You choose the most common type of staining techniques called G- banding to label the fetus chromosomes with Glemsa dye.
After taking photos of the chromosomes from a microscope, you sort the (7)____pairs of autosomes in the following order, from (8)____to (9)____, and keep the sex chromosomes last. The sorted photographed image of chromosomes is called (10)____. Now, you are ready to examine the karyotype of the fetus.

Answers

Answer:

1 monosomy

2 trisomy

3 Down syndrome

4 Turner syndrome

5 non-disjunction

6 metaphase

7 twenty-two

8 largest (chromosome 1)

9 smallest (chromosome 22)

10 karyotype

Explanation:

Non-disjunction during meiosis I or II occur when homologous chromosomes or sister chromatids refuse to separate. This makes the resulting gametes to have too many or too few chromosome numbers in their genomes.

A gamete with too few chromosome number that participates in fertilization with a normal gamete will result in a zygote with abnormally less chromosome number. This situation is referred to as monosomy. Whereas, the fusion of a gamete with too many chromosome number with a normal gamete will result in a zygote with too many chromosome, a situation known as trisomy.

The manifestation of monosomy and trisomy in humans results in Turner and Down syndromes respectively.

Humans have 23 pairs of chromosomes out of which a pair determines maleness or femaleness - the sex chromosome. Other chromosomes are referred to as autosomes. Hence, there are 22 autosome pairs and 1 pair of sex chromosome.

Chromosomes are studied by karyotyping, a process that involves photographing chromosomes at the metaphase stage of the cell cycle, cutting them out, and then arranging them in decreasing order of size.

Answer:

The correct answer is - To withstand the high pressure of the outflow of blood from the Heart.

Explanation:

The heart pumps blood to different body parts at high pressure so that it can easily reach all the parts of the body quickly. To able to hold the pressure of the blood pumped at high-pressure arteries need thick walls.

This pressure can be experienced as pulse and which required the walls of arteries and the middle layer or the tunica media to make it much thicker in arteries than in veins. In veins pressure caused by blood is very low pressure that allows them to be thin walls.
