lake tefillin is a large freshwater lake that is popular for recreation. one year, the managers of the lake introduced a population of rainbow trout to the lake. the graph shows the growth of the population over several years.
which best describes the growth pattern of the rainbow trout?
a) exponential growth,because the lake provides unlimited resources to the population
b) logistic growth, because the effect of limiting factors increased with the population size
c) exponential growth, because limiting factors are always affecting the population
d) logistic growth, because the lake provides unlimited resources until the population reaches carrying capacity
Answer:
b) logistic growth, because the effect of limiting factors increased with the population size
Explanation:
The S-shaped curve in the graph above depicts a typical logistic growth pattern.
In this type of growth pattern, there is an initially exponential growth at the beginning when limiting factors of growth are minimal. As the initial population increases, resources for growth become limited. Growth starts to slow down. And at some point, insignificant increase in population growth sets in. This is depicted on the graph where the tail end of the curve levels of and fluctuates.
This logistic growth curve shows that, over the years, the limiting factors that slows down growth of Rainbow trout population increases as the population of Rainbow trout increased. This led to the growth rate slowing down and eventually levels up with no real significant change in population size of Rainbow Trout.
Suppose a bacterial infection kills off most of the prey at point B on the graph. How would this affect the predator and prey growth curves on this computer model at point C? At point D?
If an infection kills most of the prey at a point ( B ) before the predators can get to the preys at point ( c ). The number of predators between points B and C will reduce due to the unavailability of prey to feed on.
Therefore at points C and D the amount of available predator will decrease while the number of available prey will gradually increase because of the scarcity of predators which would have negatively contributed to their growth just like the bacterial infection.
Hence we can conclude that The predator growth curve at point C and D will be ; Negative ( decreases ) while The prey growth curve at point C and D will be ; Positive ( Increases ).

are forest fires biotic or abiotic
Answer:
biotic
Explanation:
because bio means life then forest fires must be biotic
Fire is non-living, and non-living elements are the abiotic elements in an ecosystem. Thus, fire is an abiotic element in an ecosystem, but rarely mentioned.
The forest ecosystem is made up not only of living organisms (trees, animals, plants, and other living things) but also of non-living organisms (soil, water, air, and landforms) that make up the forest ecosystem.
A forest ecosystem’s abiotic elements include oxygen-rich air, water present in several bodies of water, organic compounds in the trees and soil, and dead plant and animal remains.

^^ which of the following would have the highest species richness?
The correct answer as to which has the highest species richness would be an ecosystem with 30 species with varying numbers of each population.
The species richness of an ecosystem literally refers to the number of unique species in that ecosystem irrespective of the population size of each of the species. For example, an ecosystem with 20 species each with a population size of 50 is richer in species than an ecosystem with 10 species each with a population size of 200. This is why the species richness of an ecosystem is one of the attributes used in measuring the diversity of that ecosystem.
Hence, an ecosystem with 30 species is richer than those with 25, 15, and 5 irrespective of the population size of each species.

People often say that dogs are "man's best friend.How closely related are dogs and humans? To complete this activity, you will need a computer with Internet connection, a piece of paper, a pen or pencil, and crayons or markers.Search the Internet to find the taxonomy of the domestic dog and humans, from domain through species. Check at least three different sources to make sure the information you find is correct. Try using websites that end in .Gov or .Edu; they are usually reliable.Create a chart listing the taxonomy of each species side-by-side, similar to the chart shown below.
Answer:
See explanation
Explanation:
Taxonomy actually means “arrangement law”. It is the branch of biology that deals with the classification of organisms.
The taxonomic classification system was invented by Carl Linnaeus. It is a hierarchical model of classifying living organisms based on shared characteristics.
Dogs are referred to as 'man's best friend' partly owing to some level of taxonomic relationship between the two species. Dogs and man belong to a class of vertebrates known as mammals- one of the shared characteristics of mammals is that they give birth to their young ones alive.
The taxonomic classification of man is:
Domain: Eukaryote - Kingdom - Animalia Phylum - Chordata Subphylum - Vertebrata Class - Mammalia Order - Primates Family - Hominidae Genus - Homo Species - sapiens.
The taxonomic classification of dog is:
Domain: Eukaryote - Kingdom - Animalia Phylum - Chordata Subphylum - Vertebrata Class - Mammalia Order - Carnivora Family - Canidae Genus - Canis Species - lupus familiaris

Answer: mouth = chemical physical stomach = chemical physical small and large = physical
Explanation: my mom taught me this she is a doctor
Answer:
Explanation:
Mouth is physical and chemical, the act of chewing is physical by tearing food into smaller pieces, and your saliva is chemical by beginning to break down carbohydrates.
Stomach is chemical and physical.
Churning in the stomach and peristalsis is also part of mechanical digestion. Peristalsis is the involuntary contraction and relaxation of the muscles in your stomach. Chemically your stomach breaks down proteins with hydrochloric acid.
Small Intestine has both, for physical it has segmentation and peristalsis, which helps mix the food mush with digestive juices, and chemical with the secretions of enzymes that help break down protein, fat, carbs, in order for the body to absorb different molecules.
Large Intestine is also both. Physically water is absorbed back into the body. Chemically, bacteria breaks down undigested materials, and helps produce certain vitamins.

A. 4
B. 5
C. 3
D. 2
Answer:
im pretty sure its 2 joints a day
Explanation:
The abuse of drugs can lead to serious health problems. Smoking THREE (3) marijuana joints per week for 3-6 months carries the same risk for developing lung cancer as smoking a pack of cigarettes a day for 20-30 years (Option C).
Drug abuse refers to the inappropriate and/or excessive use of a drug, which generates dependence. Cannabis or 'marijuana' is a well-known psychoactive drug derived from the Cannabis plant. The Cannabis plant contains tetrahydrocannabinol (THC), which is the main psychoactive constituent of marijuana. This substance (THC) binds to cannabinoid receptors in nerve cells (neurons) and thus induces the release of different hormones.Marijuana contains more than 500 chemical substances (some of them carcinogenic), it is for that reason that marijuana smoking can lead to lung cancer.Marijuana smoking may also cause chronic bronchitis.In conclusion, smoking THREE (3) marijuana joints per week for 3-6 months carries the same risk for developing lung cancer as smoking a pack of cigarettes a day for 20-30 years.

Force and velocity are different because
Answer:
A force pushes or pulls on an object, but velocity is simply something an object has.
Explanation:
Force and velocity are different because force measures the power or strength through which an object with a specific mass accelerates in a particular direction while velocity measures the speed of a moving object in a specific direction.
What is a Force?A force may be defined as a process of pushing or pulling on an object with mass that significantly causes it to alter its velocity. It is a vector quantity that has both magnitude and direction.
Velocity is characterized as the distance covered by an object in a unit of time. In a more simple sense, it is also defined as the displacement of the object in unit time. It is a vector measurement of the rate and direction of motion.
Therefore, force measures the power or strength through which an object with a specific mass accelerates in a particular direction while velocity measures the speed of a moving object in a specific direction.
