Answer:
246
Explanation:
Increased amount / current population = 972
Amount released = 108
time(t) = 2years
Using the exponential growth function :
f(t) = A*g^t
Where g = growth rate
To obtain the growth rate = g
972 = 108 * g^2
g^2 = 972 / 108
g^2 = 9
g = 3
To determine population after 9 months :
9 months to years = (9/12) = 0.75
t = 0.75
f(0.75) = 108*(3^0.75)
f(0.75) = 108 * 2.2795070
f(0.75) = 246.18676
= 246
Answer: c
Explanation: THE REFRACTORY PERIOD OF CARDIAC MUSCLE IS LONGER THAN SKELETAL MUSCLE
Cardiac muscle does not exhibit tetanus because it has a long absolute refractory period, electrical synapses, and relies primarily on aerobic respiration.
Cardiac muscle is a specialized type of muscle found in the heart. Unlike skeletal muscle, which can exhibit tetanus (sustained contraction), cardiac muscle does not. This is due to several factors.
Firstly, cardiac muscle has a long absolute refractory period. The absolute refractory period is the period of time during which the muscle cannot be stimulated to contract again. This refractory period allows the heart to relax and refill with blood before the next contraction. It prevents the muscle from being stimulated again before it has fully relaxed.
Secondly, cardiac muscle cells are connected by electrical synapses called gap junctions. These gap junctions allow electrical signals to pass quickly from one cell to another. This synchronized contraction prevents tetanus from occurring.
Lastly, cardiac muscle relies primarily on aerobic respiration. Aerobic respiration provides a steady supply of energy for contraction without the buildup of metabolic waste products that can lead to tetanus.

population, community, organism, biome, ecosystem, biosphere
b.
organism, community, population, ecosystem, biome, biosphere
c.
biosphere, biome, ecosystem, community, population, organism
d.
organism, population, community, ecosystem, biome, biosphere
The proper order, from smallest to largest, for the levels of organization is d. organism, population, community, ecosystem, biome, biosphere.
Hence, the proper order, from smallest to largest, for the levels of organization is d. organism, population, community, ecosystem, biome, biosphere.
Learn more about biosphere:
The correct order from smallest to largest is organism, population, community, ecosystem, biome, and biosphere. This hierarchy is essential for understanding ecological relationships and how biological organization is structured.
The levels of biological organization form a hierarchy in which each level builds upon the one below it. At the very basic level, we have the organism, which is an individual living entity. A group of organisms of the same species that live in the same area is called a population. When multiple populations of different species interact in an area, they form a community. The community, along with the nonliving components of the environment, constitutes an ecosystem. A biome is a larger area that includes multiple ecosystems with similar climates and vegetation. Finally, the biosphere encompasses all the biomes and represents the global ecological system integrating all living beings and their relationships, including their interaction with the elements of the lithosphere, hydrosphere, and atmosphere.
Given the provided hierarchy, the correct sequence from smallest to largest is:
Therefore, the correct answer to the student's question is option d: organism, population, community, ecosystem, biome, biosphere.

Your new friend has demonstrated clanging.
Clanging is a mode of speech described by connections of words or phrases joined only by sounds and not by meaning. Clanging is a behavior that is circumstantially unsuitable. Clanging may include uncontrolled and unconscious rhyming or repetition of sounds without clear logical association between words. Also, clanging is indicative of some mental disorders such as mania and schizophrenia.

OPTIONS:
a. The organisms vary in trait
b. The variation is inherited
c. More young are born than can survive
d. Some individuals are better adapted to the environment
Answer:
d. Some individuals are better adapted to the environment
Explanation:
Kettlewell’s biological experiment, which was conducted in England, was to study the evolutionary changes taking place in trees in relation to the appearance of dark-colored moth.
It was observed that white moths were more common before the industrial revolution. After the industrial revolution, which changed the background of the environment of the moths due to pollution, the moths became easily seen and obvious to predatory birds.
It was discovered that peppered moths were selectively preyed on by birds depending on their body color, which serves as the most important factor that determines if moths can survive predation by blending with the background of their environment. This led to the evolving of moths of their color to blend with the background of their environment, which makes them hide from the birds that prey on them.
Kettlewell was trying to verify the factor in evolution by natural selection, which says, “some individuals are better adapted to the environment”.
