<h2>False </h2>

Explanation:

Alimentary canal components include mouth, pharynx, esophagus, stomach, small intestine and large intestine whereas liver is a component of the accessory digestive system

The liver is a large organ that is located in the upper right portion of abdomen, beneath the diaphragm
The liver has two large sections, called the right and the left lobes and the gallbladder sits under the liver, along with parts of the pancreas and intestines
The liver and these organs work together to digest, absorb, and process food
The liver's main role is to filter the blood coming from the digestive tract, before passing it to the rest of the body
The liver also detoxifies chemicals and metabolizes drugs
The liver secretes bile that ends up back in the intestines and also makes proteins important for blood clotting and other functions

Energy flow in an ecosystem is best represented by _______.

kondaur [170]

Answer: Pyramids of biomass
Pyramids of biomass display the weight of organisms at each level. Inverted pyramids of biomass can occur when the primary producer has a high turnover rate. Pyramids of energy are usually upright and are the best representation of energy flow and ecosystem structure.

A well-insulated home, with energy-efficient windows and sealing that prevents air leaks to the outside, can act as

ahrayia [7]

As long as there is no energy transference between the exterior and the interior, and no matter movement, then this home could act as an ideal isolated system.

<h3>What is a loop system?</h3>

The Loop system is a process, a system, or a circular structure that ends at the same point at which it starts.

<h3>What is an open system?</h3>

The open system is the thermodynamic system that allows the interchange of matters and energy between its exterior and interior. There is an interaction between the system and the environment.

<h3>What is a closed system?</h3>

The thermodynamic closed system is the system that allows the interchange of energy between the exterior and the interior, but there is no matter interchange. Nos substances or elements can get in or get out of these systems. Only energy as hit or work.

<h3>What is an isolated system?</h3>

The thermodynamic isolated system is the one that does not interact with the environment in which it is immersed. The isolated system does not allow the interchange of matters or energy between its exterior and interior.

In the exposed example, if there is no energy transference between the exterior and the interior, and no matter movement, then this home could act as an ideal isolated system.

Neurons in the ______ , control motor reflexes.

yan [13]

Neurons in the <u>spinal cord</u>, control motor reflexes, which allows rhythmic and automatic movements to be carried out.

The spinal cord represents the lowest level in the hierarchical system that regulates reflex motor activity, voluntary movements, and body posture.

Therefore, their neurons have been organized into circuits that participate in simple automatic gait movements and simple defensive movements (withdrawal of the muscle in the event of any aggression) through reflex responses.

The motor neurons of these circuits are located in the anterior horns where they are arranged forming the so-called "poles" of motor neurons, equivalent to true motor neuron nuclei.

Alpha motor neurons their axons are myelinated and they group together in the medulla and form columns that are known as motor nuclei.

Gamma (γ) motor neurons innervate muscle fibers of the muscle spindle.

Interneurons can be excitatory or inhibitory.

Therefore, we can conclude that neurons in the spinal cord, control motor reflexes, they present functional interactions between them and this allows rhythmic and automatic movements to be carried out with ease through reflex responses.

The Punnett square illustrates a cross for color of the flower.

matrenka [14]

Answer:

Human skin color is a good example of polygenic (multiple gene) inheritance. Assume that three "dominant" capital letter genes (A, B and C) control dark pigmentation because more melanin is produced. The "recessive"alleles of these three genes (a, b & c) control light pigmentation because lower amounts of melanin are produced.
