The epiglottis is a:_________.
a. muscle that moves the trachea out of line with the pharynx during swallowing.
b. flap of cartilage that flips down to cover the entry to the trachea during swallowing.
c. muscle that moves the esophagus in line with the pharynx during swallowing.
d. sphincter that closes off the entry to the trachea during swallowing.

Answers

Answer 1

Answer:

b. flap of cartilage that flips down to cover the entry to the trachea during swallowing

Explanation:

The function of the epiglottis is to prevent food and liquids from entering the windpipe (trachea) and the lungs. It is a flap of cartilage that stands upright when we breathe, allowing air to pass into the larynx and lungs. But while we are eating or drinking, it flips down over the opening of the trachea to prevent food and liquids from getting in there.

Hope that helps.

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

Answers

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.

The story brought to mind many characters of situations:

Beauty and BeastThe cuddle of eternal loveThe faith and nature of life are indeed visible in this story.

Such as the above story, Psyche appears to believe that she'll be wanted to send to have been the bride of such a terrifying dragon who conceals from her after week as well. Very much like that novel, she was therefore persuaded by her sisters to deceive himself, who forced herself to inform on him. Cupid waking someone up from her deep sleep is like the conventional Touch of true soul mate administered by innumerable royalty to activate respective princesses.

Answers

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.

Explanation:

After about two minutes of exercise, muscles require oxygen to continuously produce energy. Carbon dioxide is a byproduct of energy production and must be removed from the muscles to maintain homeostasis.

Answers

Answer:

When exhaling and inhaling, respiratory homeostasis occurs, exchanging gases at the level of the pulmonary alveolus.

This process is in charge of removing carbon dioxide from the muscles and their subsequent oxygenation.

Explanation:

Hemoglobin is in charge of associating carbon dioxide and delivering oxygen to the muscle that suffered physical activity.

Excess carbon dioxide is pathological, causing muscle acidosis in the muscle and even its possible denaturation since it is highly contained by proteins.

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?

Answers

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.

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

Answers

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.

Answers

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.

Cellular respiration converts the reactants' oxygen and glucose into carbon dioxide, water, and energy. The reverse reaction of photosynthesis converts reactants of carbon dioxide and water into oxygen and glucose. These two reactions are part of which biogeochemical cycle?

Answers

Answer:

Photosynthesis and Cellular respiration take place in the carbon cycle

Explanation:

One of 4 biogeochemical cycles

carbon cycle

Carbon moves from living things to the atmosphere. Each time you exhale, you are releasing carbon dioxide gas (CO2) into the atmosphere. Animals and plants need to get rid of carbon dioxide gas through a process called respiration.

Photosynthesis removes carbon dioxide from the atmosphere, while cellular respiration releases it into the environment. Cellular respiration and photosynthesis are significant carbon cycle processes. The carbon cycle refers to the procedures used to recycle carbon in the biosphere.

What cellular respiration in biogeochemical cycle?

The exchange of carbon between the biosphere, geosphere, hydrosphere, atmosphere, and pedosphere occurs in one of the biogeochemical cycles. Photosynthesis occurs when carbon dioxide and sunshine are combined in green plants.

Therefore, living beings release carbon into the atmosphere. You emit carbon dioxide (CO2) into the atmosphere with each exhalation. Through a process known as respiration, organisms such as animals and plants must expel carbon dioxide gas.
