Fill in the blanks:
1. Light-touch receptor located at the epidermal-dermal border:__________.
2. Light-pressure receptor located in papillary layer of dermis: ____________.
3. Deep pressure receptors:__________.
4. Receptors that respond primarily to pain and temperature:________.
a. Merkel cells.
b. nociceptors.
c. lamellated corpuscle.
d. tactile corpuscle.
Answer:
1. merkel cells
2. tactile corpuscle
3. lamellated (lamellar) corpuscle
4. nociceptors
Explanation:
Merkel cells are epithelial cells found around hair follicles which are capable of sensing gentle touch sensations such as, for example, tactile discrimination and environmental exploration. Tactile corpuscles are a class of nerve ending required for mediating sensitivity to light touch sensations. The lamellar corpuscles are another class of nerve ending capable of sensing deep touch sensations and vibrations. Finally, nociceptors are somatic sensory receptors capable of sensing noxious (damaging) stimuli.
1. Light-touch receptor located at the epidermal-dermal border: Tactile corpuscles (D)
Light-touch sensors called tactile corpuscles, sometimes referred to as Meissner's corpuscles, are situated near the epidermal-dermal boundary. They are located in the papillary layer of the dermis's dermal papillae, which are tiny, finger-like projections.
Particularly dense populations of tactile corpuscles can be seen in skin regions like the lips, palms, and fingertips that are sensitive to gentle touch.
2. Light-pressure receptor located in the papillary layer of the dermis: Merkel cells (A)
3. Deep pressure receptors: Lamellated corpuscle (C)
4. Receptors that respond primarily to pain and temperature: Nociceptors (B)

A person cannot produce several types of proteases. Name the problem this specific person probably has and explain why.
Answer:
The person have excess amount of proteases and when this happen, the person will protein breakdown in the body or lack of protein in the body which can affect most of the organs in the body.
Explanation:
Under normal conditions in the body, blood and body tissues have a specific potent enzyme called proteases. Protease help in the breakdown of protein in the body and play important roles in defending or fight against incoming infections and inflammatory processes in the body .There is need for thslese proteases to be regulated or control because overactivity can lead to protein destruction which will lead damage of different body organs. In order to control this, blood and other tissues in the body posses enzymes with protease inhibitory activity, these enzymes help to prevent its from undergoing excessive action and potentially harmful effects.

Why do plants produce more carbon dioxide than oxygen during the night?
A. Respiration can only occur when there is no available sunlight.
Ο Ο Ο
B. Photosynthesis only produces carbon dioxide during the night.
C. Respiration can happen without sunlight, but photosynthesis
cannot.
D. Respiration produces oxygen during the day and carbon dioxide at
night
SUBMIT
Answer:
C. Respiration can happen without sunlight, but photosynthesis
cannot.
Explanation:
Respiration is the metabolic process by which the cells of living organisms, plants inclusive, obtain energy. Photosynthesis, on the other hand, is the process whereby plant cells synthesize their food in form of sugars (glucose).
Photosynthesis takes place in two stages namely: light dependent stage and light independent stage. The light dependent stage occurs strictly in the presence of sunlight, where oxygen gas is released as a product. Hence, it can only occurs during the day. Respiration, which breaks down the sugar product of photosynthesis to produce energy, occurs at anytime (day or night). Carbon dioxide (CO2) gas is released as a product.
Since the light dependent stage of photosynthesis cannot occur without sunlight, it cannot occur at night. this means that oxygen gas will not be released at night. However, respiration which occurs during daytime and nighttime continually releases carbon dioxide gas. This accounts for the reason CO2 gas is produced more by plants than oxygen at night.

Explanation:
After surgical removal of the spleen (i.e., a splenectomy), some other organs take over most of its functions. Which of the following spleen functions in the adult can not be performed by bone marrow?
A) immune surveillance
B) erythropoiesis
C) removal of aged and damaged red blood cells from the blood
D) storage of platelets
Answer:
removal of aged and damaged red blood cells from the blood
Explanation:
Spleen is an organ found in vertebrates and it is located in the upper part of the abdomen that act majorly to filter blood. It recognizes and removes old, malformed, or damaged and aged red blood cells. When blood flows into the spleen, the spleen performs "quality control"; the red blood cells must pass through a maze of narrow passages.
The bone marrow is a spongy tissue that produced red blood cells and this perform similar function as the spleen except that it cannot remove aged and damaged red blood cells from the blood this is because it does not have the ability to remove age and damage red blood cells due to inability to support the immune system.
The spleen help remove age and damage red blood cells thereby boosting the immune system in fighting against infections ,preventing blood clot .
Review the numbered items below. Then, decide which of the following lists the correct steps of translation in the correct chronological order.
I. UGA codon is identified.
II. DNA is unwound to expose a single template strand.
III. tRNA molecules carrying various amino acids bond to mRNA based on the sequence of mRNA codons.
IV. mRNA arrives at the ribosome
V. Introns are snipped out of an mRNA molecule.
V. tRNA, carrying methionine amino acid, bind to mRNA.
Answer:
IV, VI, III, I
Explanation:
Translation is the process of synthesis of protein from with the help of messenger RNA (mRNA).
The process of translation include initiation, elongation and termination.
Initiation: In this step mRNA binds to ribososomes and tRNA, carrying start codon or methionine binds to mRNA.Elongation: In this step, the tRNA molecules carrying several amino acid bind to mRNA based on the sequence of mRNA codon and then moves (translocates) to the next mRNA codon which leads to amino acid chain.Termination: At the end, when a stop codon (UGA) identified, polypeptide is released.So, the correct chronological order is IV, VI, III, I.

The Center for Disease Control and Prevention recommended that men infected with Zika virus delay planned pregnancies. What is the recommended length of time for delayed conception for men afflicted with Zika virus?
Answer:
This should be 6 months
Explanation:
Generally ZiKa disease is caused by Zika virus,It is transmitted by Aedes mosquito as vector.It symptoms(rashes,fever,joint pains) are mild in the first week,but very severe in pregnant women.Men who visited then endemic region are advised to delay intercourse for 3 months,while those who were infected were recommended to abstain from sex for 6 months,
This is because the virus has been found in the semen longer than other body fluids.it has been found in infected semen for 180 days after healing.
In infected pregnant women,this can be transmitted to the fetus,causing microcephaly in the unborn child,Protection against mosquito bites is best way of prevention.
In exposed lady the period of abstinence should be 2 months.

Cystic fibrosis is a genetic disease that results from a malfunctioning chloride transport protein. This causes the accumulation of a thick mucous in the lungs and around the pancreas. Why might an individual with cystic fibrosis have malabsorption and nutrient deficiencies
Answer:
In cystic fibrosis, there is an alteration in the chlorine channels of all cells, so all kinds of body secretions are affected.
Body fluids thicken at the intestinal level, forming a mucus that blocks the ducts that carry digestive enzymes from the pancreas to the intestine.
These enzymes are responsible for generating nutrients or proteins, vitamins and even fats are absorbed.
Explanation:
This intestinal factor results in malnutrition, growth impairment, hypovitaminosis, decay, anemia, capillary fragility, decline and fatigue.

Mules are considered to have many superior characteristics compared to the horse or burro. Mules are often stronger, agile, and can jump higher than either of their parents. Why are mules considered to be a weak hybrid and not a separate species?
Answer:
Because they are sterile
Explanation:
Mules are considered to be a weak hybrid and not a separate species because they are sterile and cannot produce progeny of their own.
Mules are hybrid products from two separate species - a donkey and a horse.
A species is generally defined as a group of organisms that are capable of breeding to produce fertile offspring. Hence, in order for them to have the potential of being categorized as a separate species, they must be able to produce their own progeny but this is not the case.
A sudden volcanic eruption kills many members of a population of elk. By chance, the individuals that remain do not have the same mix of genes as the original population. The mechanism of evolution is:_________.
