(c) Based on the data, describe the time period during which Chlorella approximates exponential growth. Based on
the data and assuming logistic growth, describe the time period during which the Chlorella population has reached
the carrying capacity of the culture. Based the data, calculate the growth rate per day for the 5-day period with
the greatest growth rate.
Populations that experience a logistic growth model depend on the density and available resources. A) 5 - 10 days. B) 25 - 30 days. C) 0.27 x 10⁶cells/mL/day
What is the logistic growth model?In a logistic growth model, the population growth depends on density. Natality and mortality depend on the population size, meaning that there is no independence between population growth and population density.
When a population grows in a limited space, density rises gradually and eventually affects the multiplication rate. The population per capita growth rate decreases as population size increases.
The population reaches a maximum point delimited by available resources, such as food or space. This point is known as the carrying capacity, K.
K is a constant that equals population size at the equilibrium point, in which the natality and the mortality rate get qual to each other.
Assuming that the population size is N, when
N<K, the population can still grow. N approximates to K, the population's growth speed decreases. N=K the population reaches equilibrium, N>K, the population must decrease in size because there are not enough resources to maintain that size.The sigmoid curve represents the logistic growth model.
In the example,
Between 0 and 5 days the population remains relatively stableBetween 5 and 10 days Chlorella approximates exponential growth.Between 10 and 20 days Chlorella experiences exponential growth. Between 20 and 25 days the population is near the K and decreases its growth rate.From 25 to 30 days, the population reached the equilibrium point, and got to stabilize.Time period during which Chlorella,
A) approximates exponential growth ⇒ Between 5 and 10 days
Between 10 and 20 days its already exponential growth.
B) has reached the carrying capacity of the culture ⇒ 25 to 30 days
Finally,
C) Growth rate per day for the 5-day period with the greatest growth rate.
First we need to figure out during which period Chlorella experiences the greatest growth rate. To do it, we just need to make the following substraction,
Growth rate per period = final concentration - initial concentration
Period 0-5 ⇒ 0.08 - 0.01 = 0.07Period 5-10 ⇒ 0.55 - 0.08 = 0.47Period 10-15 ⇒ 1.9 - 0.55 = 1.35Period 15-20 ⇒ 2.8 - 1.9 = 0.9Period 20-25 ⇒ 3.2 - 2.8 = 0.4Period 25-30 ⇒ 3.2 - 3.2 = 0Now we know that during the period from 10 to 15 days, the population experienced its greatest growth rate. But this rate is acchieved in 5 days. Now we need to find out the growth rate per day. So all we need to do, is to divide the result of the substraction per 5 days,
1.35 x 10⁶ / 5 days = 0.27 x 10⁶ cells/mL/day
The answer is 0.27 x 10⁶ cells/mL/day

what is the difference between the way that saprotrophs and detritivores digest their food
Answer:
Externally
Explanation:
Usually, detritivores are mostly animals, while saprotrophs are mostly fungi. Furthermore, detritivores consume lumps of dead organic matter separately, while saprotrophs absorb chemically digested food. Saprotrophs digest their food externally, whereas detritivores do it internally in the digestive system.

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.

Answer:
b. Order Anura: 28 families, 338 genera, 4360 species
The families are biggest part followed by genera and then each genera has multiple species, this is described by nomenclature of biological species. Therefore option B is correct as the numbers are also increasing because families will be fewer than genera and genera will be fewer than species.

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.

3. Compare and contrast the movement produced by each of the three types
Answer:
strike-slip is when the blocks have mostly moved horizontally, normal is when a dip-slip fault in which the block above the fault has moved downward relative to the block below, and thrust is when the hanging wall moves up relative to the footwall.
There are three faults. Normal faults originate from the divergent boundary. Reverse faults originate from the convergent boundary. Strike-slip fault originate from transforming boundary.
What are the three types of fault?We can differenciate three types of faults,
Normal fault ⇒ originate from divergent movementReverse fault ⇒ originate from convergent movementStricke-slip fault ⇒ originate from transforming movementWhat are the boundary types?I. Divergent:
This boundary occurs when two plates separate and molten material rises from the mantle creating a new crust.
The hot material creates a new seabed between the separating plates, expanding the sea bottom.
II. Convergent.
Collision area between two plates. Two oceanic plates might collide, or one oceanic plate with a continental one.
In this last case, the oceanic crust sinks under the continental plate, and magma rises to the surface by crevices.
The thicker and older plate subduces under the other plate.
III. Transforming.
The plates slide laterally with each other, and they are usually called faults.
It is associated, in general, with the oceanic ridge, although it might also occur in the continental plate.
No rocky material is either destroyed or formed.
When the plates move and produce a displacement of one transforming limits from side to side, earthquakes occur.
The movement breaks the crust and originates pronounced fractures.
