Animal Tissue and Anatomy Questions

Multiple choice

The word part "pod" means _,

  1. foot

  2. false

  3. cilia

  4. flagella
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The root 'pod' comes from the Greek word for foot. It is commonly used in biological terms like pseudopod (false foot) or arthropod (jointed foot).

Multiple choice

Which body system is most closely associated with the ER of a Cell?

  1. Nervous System

  2. Digestive System

  3. Circulatory System

  4. Endocrine System
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The endoplasmic reticulum (ER) is a transport system within the cell, analogous to the circulatory system which transports materials throughout the body. The other systems have different primary functions.

Multiple choice

Which structure keeps food from entering the trachea?

  1. Cartilaginous rings

  2. Epiglottis

  3. Glottis

  4. Larynx
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The epiglottis is a flap of cartilage that covers the trachea during swallowing to prevent food from entering the airway. The glottis is the opening itself.

Birds that wade in water have

  1. Webbed feet

  2. Clawed feet

  3. Long legs

  4. Short legs
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Some birds, like cranes, wade in the water. They have long feet and toes. Along with long feet, they are also seen having long necks. As they move around in shallow waters, having long feet helps them in keeping their feathers high above the surface of the water. Thus they are kept dry and don't get wet with water even when the birds search for food inside water. This forms a part of their important adaptive behavior.

So, option C ''Long legs'" is the correct answer.

It can be said that some animals in their evolutionary development preferred to be conformers than regulators. 
Which of the following can be the best suited reason for it?

  1. The metabolic of these organisms can occur at a very wide rang of temperature.

  2. Maintaining homeostasis is an energetically expensive process

  3. The enzymes of these organisms are functional at high temperatures.

  4. Both B and C
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Maintaining homeostasis, especially thermoregualtion is energetically expensive for many organisms. During the course of evolution, the costs and benefits of maintaining a constant internal environment were taken into consideration and thus some species preferred to be conformers.

Multiple choice biology human body and organ system blood pressure circulatory system transportation in animal and plants

Some horses develop nose bleed during races perhaps because of

  1. The high cholesterol in their blood

  2. The high blood pressure involved

  3. Their need to bring down their body temperature

  4. All of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Exercise-Induced Pulmonary Haemorrhage (EIPH), commonly known as bleeding, is the most widely recognized of all disorders affecting racehorses. EIPH is characterized by bleeding from the lungs after strenuous exercise. Research studies have shown that horses experience unusually high blood pressures within the lungs during exercise. Deep within the lung, thousands of tiny air sac or alveoli interface with capillaries, forming the blood-gas barrier. This incredibly thin barrier readily allows oxygen to move from the lungs into the blood (and carbon dioxide to move in the opposite direction). This blood-gas barrier is not sufficiently strong in horses, to withstand high stress on the capillary wall, that exist during races or intense exercise. Due to which some lung capillaries get ruptured and release blood into the airways. The term "pulmonary capillary stress failure" is also used to describe this phenomenon. 

So, the correct answer is option B.

Choose the correct answer from the alternatives given.
In an one-circuit circulatory system, blood pressure:

  1. cannot be determined

  2. is higher at the intestinal capillaries than at the gill capillaries

  3. drops significantly after gas exchange has taken place

  4. is constant throughout the system
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
In a single-circuit circulatory system as seen in fishes, the oxygenated blood from the gills does not enter the heart. The heart does not receive oxygenated blood, so known as venous heart. It is directly distributed in the entire body, after which it loses its pressure due to the absence of pushing force. Only the deoxygenated blood enters the auricle and then the ventricle. The deoxygenated blood enters the gills for oxygenation from the ventricle. Blood has a slow flow and low pressure.
So, the correct option is 'drops significantly after the gas exchange has taken place'.
Multiple choice innate and learned behaviour option a: neurobiology and behaviour biology

Organ most affected by alcohol is

  1. Heart

  2. Cerebrum

  3. Liver

  4. Cerebellum
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
The organ most affected by alcohol is cerebellum which is part of brain. When alcohol is absorbed into blood stream, it reaches brain cells because it can easily cross the barrier between brain and blood. It damages brain cells specially of cerebellum. Cerebellum controls balance and movement of body and other motor functions. Due to this, person loses self control and is not even able to stand properly. Loss of muscle coordination occurs due to which speech becomes incoherent. Alcohol also increases reaction time due to which body takes more time to respond to stimulus.
So, the correct answer is 'Cerebellum'.
Multiple choice

A ________ is usually necessary when feeding Dairy Cows TMR rations.

  1. Mixer box on a truck or trailer

  2. Vertical concentrate bin

  3. Feed trough or bunk feeder in milk barn

  4. Auger system in parlor
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A Total Mixed Ration (TMR) requires a mechanical mixer (truck or trailer mounted) to ensure that all ingredients are blended uniformly so the cow cannot sort the feed.

Multiple choice

Where are degradable proteins broken down?

  1. Rumen

  2. Reticulum

  3. Omasum

  4. Abomasum
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Degradable intake protein (DIP) is broken down by the microbial population residing in the rumen. This microbial fermentation allows the cow to utilize nitrogen sources for protein synthesis.

Multiple choice

Milk fever is also (scientifically) known as what?

  1. Parturient paresis

  2. Postpartum paresis

  3. Mamogenesis

  4. Masticular Paresis
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Milk fever, or hypocalcemia, is clinically referred to as parturient paresis. It occurs when a cow cannot mobilize enough calcium from its bones to meet the demands of lactation shortly after calving.
