All the modern species of bison have evolved overtime just as all living organisms evolve over time.
Answer:
The working assumption for many years was that, like North American bison, European bison evolved from steppe bison. ... Their results suggest that the European bison is the result of inter-breeding, over 120,000 years ago, between steppe bison and aurochs; the wild ancestors of modern domestic cattle.
Our study suggests that the first bison arrived in North America 195 - 135 thousand years ago over a land bridge between Asia and Alaska. They quickly spread and evolved (changed) into different forms to adapt to their new environments.

Compared to the inertia of a 1-kilogram mass, the
inertia of a 4-kilogram mass is
A. 16 times as great
B. 1/16 as great
C. 1/4 as great
D. 4 times as great
please help.
Answer:
D. 4 times as great
Explanation:
The inertia of an object is the resistance offered by the object to change in its motion or position.
Then concept of inertia is obtained from Newton's first law of motion which states that an object which is not subjected to any net external force will remain its position of rest or constant velocity of motion until some net external force acts on it. The object at rest will then start to move whereas the object moving at constant velocity will experience a change in its speed or direction of motion.
This reluctance to change position is greater, the more massive an object is as well as the higher the speed of motion of the object. Thus, inertia is directly proportional to the mass of the object as well to the velocity of an object in motion.
From Newton's first law, inertia can be calculated as the force to be overcome to mobile an object, i.e. Inertia = F = ma
Where m is mass of object, a = acceleration of the object.
Objects on the earth's surface experience a constant acceleration, g.
Thus for a 1 kg mass, Inertia = 1 × g
For a 4 kg mass, inertia = 4 × g
The inertia of a 4 kg mass is four times as great as a 1 kg mass.
The inertia of a 1-kilogram mass, the inertia of a 4-kilogram mass is - D. 4 times as great
Inertia is the property of matter that resists changes in motion. Mass is the quantitative matter of motion.
Mass is that quantity that is solely dependent upon the inertia of an object.The more inertia that an object has, the more mass that it has.A more massive object has a greater tendency to resist changes in its state of motion.Thus, the inertia of a 1-kilogram mass, the inertia of a 4-kilogram mass is - D. 4 times as great.

5) represent codons which are groupings of 3 consecutive nucletides
Explanation:
Opposites for REGULAR mDNA base pairings are T= A and G = C, however, since it is mRNA, your base pairings change a little. G is still to C BUT Thymine (T) becomes Uracil (U) so A= U instead of A= T. So big difference between mRNA and mDNA is that Thymine changes to Uracil and vice versa depending on how the code is being translated.

Neuromodulation is the release of chemicals (other than ____________ ) from cells that locally regulate or alter the response of neurons to neurotransmitters. The substances released are called ____________ . Neuromodulation generally results in either facilitation or inhibition. When there is greater response from a postsynaptic neuron because of the release of neuromodulators it is ____________ . This may result from either ____________ amount of neurotransmitter in the synaptic cleft or ____________ number of receptors on postsynaptic neurons. When there is less response from a postsynaptic neuron because of the release of neuromodulators, it is called ____________ . This results from either ____________ amount of neurotransmitter in the synaptic cleft or ____________ number of receptors on postsynaptic neurons.
Answer:
Neurotransmitters; neuromodulators; facilitation; an increased; an increased; inhibition; a decreased; a decreased.
Explanation:
In Biology, stimulus can be defined as an obvious change in either the chemical or physical structure of an organism' environment (either external or internal). Thus, all living organisms (both animals and plants) respond to changes in their environment and consequently, an appropriate response or reaction is made. Also, stimulus arising from within the organism is known as internal stimulus while those from its environment are known as the external stimulus.
In organisms, the specialized cells that detect stimulus are generally known as sensory receptors while a group of these receptors is referred to as sense organ.
Neuromodulation is the release of chemicals (other than neurotransmitters ) from cells that locally regulate or alter the response of neurons to neurotransmitters. The substances released are called neuromodulators. Neuromodulation generally results in either facilitation or inhibition. When there is greater response from a postsynaptic neuron because of the release of neuromodulators it is facilitation. This may result from either an increased amount of neurotransmitter in the synaptic cleft or an increased number of receptors on postsynaptic neurons. When there is less response from a postsynaptic neuron because of the release of neuromodulators, it is called inhibition. This results from either a decreased amount of neurotransmitter in the synaptic cleft or a decreased number of receptors on postsynaptic neurons.
The real length of one villus is 0.8 mm
Calculate the image length if the villus is viewed at a magnification of x20
magnification = size of image / size of real object

The number of chemical industries along Florida's rivers is increasing. What is the most
likely consequence of this increased industrialization?
O a decrease in the amount of water pollution
O an increase in the amount of water available for recreational use
an increase in the destruction of natural food webs
O a decrease int he amount of water needed by industry
Answer:
The correct answer would be - an increase in the destruction of natural food webs.
Explanation:
Increasing chemical industries near the river cause harmful effects to the environment by various means, including air pollution, dumping untreated chemical or industrial waste, and wastewater in the river. This will lead to a lack of potable water, contamination of the food chain, destruction of biodiversity, and many more.
The destruction of biodiversity can be caused by the increasing the unbridled growth of phytoplankton, eutrophication process that will consume more oxygen and cause algal bloom and decrease the oxygen in the water and destroys the organism and natural food web.

Explanation:
Select the correct statement about the three-chambered hearts of amphibians and nonbird reptiles. A scheme of blood circulation of reptiles except for birds. The reptiles have a three-chambered heart that consists of two atria and one ventricle with an incomplete septum. There are two circuits: pulmonary and systemic. In the pulmonary circuit, the blood from the right ventricle is pumped in to lung capillaries and returned to the left atria. In the systemic circuit, the blood is pumped from the left ventricle to the systemic capillaries via the left systemic aorta and is then returned to the right atria. There is also one vessel going from the right ventricle to the aorta right before it branches to smaller arteries. This vessel carries mixed blood. All blood on the right side of the circuits is venous and all blood on the left side is arterial. Select the correct statement about the three-chambered hearts of amphibians and nonbird reptiles. The three-chambered hearts of amphibians and nonbird reptiles are facultative, allowing variation in blood flow through the heart. The three-chambered heart is inferior to the four-chambered hearts of birds and mammals, limiting the evolutionary success of amphibians and nonbird reptiles. Pulmonary and systemic blood fully mixes in the ventricle of a three-chambered heart.
Answer:
The three-chambered hearts of amphibians and nonbird reptiles are facultative, allowing variation in blood flow through the heart.
Explanation:
In Anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.
Generally, the cardiac cycle occurs in two (2) stages;
I. Diastole : in this stage, the ventricles is relaxed and would be filled with blood.
II. Systole: at this stage, the muscles contracts and thus, allow blood to be pushed through the atria.
All amphibians and reptiles except for crocodiles (having four-chambered heart) have three-chambered hearts, which typically comprises of a partially divided ventricle and two atria.
Hence, the correct statement about the three-chambered hearts of amphibians and nonbird reptiles is that, the three-chambered hearts of amphibians and nonbird reptiles are facultative, allowing variation in blood flow through the heart due to the partially divided ventricle.
