A population of 40 killer whales lives in a bay that measures 2000 square miles. What is the population density of killer whales?
Answer:
.02
Explanation:
When finding population density, divide the amount of people, animals or things in the region by the total square miles. 40/2000 is .02.
A population is the size of the group of individuals residing at a place. A population of 40 killer whales has a population density of 0.02.
What is population density?Population density is the individual's concentration of a specific species at a particular geographical location. It allows the establishment of the ecosystem and health.
Given,
Number of individulas = 40
Size of the area = 2000
Density = Number of individuals ÷ Size of the area
= 40 ÷ 2000
= 0.02
Therefore, 0.02 is the population density of killer whales.

A student is collecting the gas produced
from the reaction of 1.5 grams of Mg with
excess HCI. When the reaction is
complete, how many moles of H2 should
have been produced?
Answer:
0.062 moles of hydrogen gas
Explanation:
We must first out down the reaction equation before we can attempt to solve the problem.
Mg(s) + 2HCl(aq) ----> MgCl2(aq) + H2(g)
Next we obtain the number of moles in 1.5 g of magnesium metal from;
Molar mass of magnesium = 24.3 gmol-1
Number of moles of magnesium= mass/molar mass = 1.5g/24.3gmol-1 = 0.062 moles
From the reaction equation;
1 mole of magnesium metal yields 1 mole of hydrogen gas
0.062 moles of magnesium metal will yield 0.062 moles of hydrogen gas
Therefore, reaction of 1.5g of magnesium metal with excess hydrochloric acid will yield 0.062 moles of hydrogen gas.

A person can eat when hunger is absent because: a. the conscious mind of the cortex can override the body's signals b. the digestive tract sends messages to the hypothalamus c. the hypothalamus signals the availability of food in the environment d. the stomach intensifies its contractions and creates hunger pangs e. the glands start supplying epinephrine to the brain
Answer:
a. the conscious mind of the cortex can override the body's signals
Explanation:
Physiologically the satiety center in the hypothalamus control hunger is the lateral hypothalamus,while the ventral hypothalamus ensures satiety,urge to stop eating.Therefore the sensation to eat is involuntary. Mammalian brain is made up of the higher brain centers,located in the Cerebral cortex. These are regions of the brain used for judgemental cases,and conscious reasons to meet the demand for immediate needs.
Once the urge of thirst and hunger has been met,the satiety center stimulation is stopped.However,if one wishes to eat despite the stimulation of the hunger center,The crave for this is control by the conscious cerebral cortex,which allow the person to make the decision,without the involuntary region of the brain.
Hence the need to it is no longer done for nourishment,but rather to meet up or carried out the habits of fulfilling the passion to eat.

Which statement best describes the cycling of carbon between the atmosphere and geosphere? Precipitation and condensation increasing the groundwater supply Glaciers melting due to an increase in global climate temperatures Volcanic activity releasing carbon into the atmosphere Trees and plants releasing carbon through respiration
Answer:
Volcanic activity releasing carbon into the atmosphere
Explanation:
In the geosphere, carbon enters when the dead and decaying matter takes the form of fossil fuels. From the biosphere, the carbon enters into the geosphere through these sources. A carbon reservoir is maintained in the geosphere through these sources. The process of weathering, erosion, and volcanic eruption exposes the carbon content of the geosphere into the atmosphere. Volcanic eruptions upturn the carbon content of the geosphere and expose them.

The researchers participating in the experiments described above were assigned to conduct new experimentation, also on Leigh syndrome-positive mouse specimens. As a precursor step, it was decided to create a new population of Leigh syndrome-positive mice. What would be the option most likely to be successful in creating this population
Answer:
Induction of intentional mutations in the mitochondria of pre-fertilization ova
Explanation:
Leigh syndrome is a neurological disorder which affects the motor and mental state of organisms. The Mitochondria is known as the power house of the cell due to its production of energy for use by various cells in the body. Most neurological problems affect the motor and mental state as a result of a mutated mitochondrion. This explains why Induction of intentional mutations in the mitochondria of pre-fertilization ova Is correct.
A population of fish has 11,140 individuals. They have a death rate of 100 per year and a birth rate of 120 per year. Assuming 50 fish migrate into the population and 25 migrate out of the population per year, how many individuals would there be after the first year
Answer:
11,185 individuals
Explanation:
The number of individuals after the first year would be 11,185.
The change in the number of individuals in a population or population size is determined by the equation:
(B - D) + (I - E), where B = birth rate, D = death rate, I = immigration, and E = emigration.
In this case, B = 120, D = 100, I = 50, E = 25. Hence, change in the population size;
= (120 - 100) + (50 - 25) = 45
This thus means that the population would have increased by 45 individuals after the first year. Since there were 11,140 individuals initially, the total number of individuals after the first year would be;
11,140 + 45 = 11,185 individuals.
