(b) increase in the population size
(c) zero population growth
(d) population explosion
(c) zero population growth
natality - birth rate
mortality - death rate
when birth rate and death rate are equal. the population remains constant and does not change. nor increase nor decrease.For example, the birth rate in a country is 500 and death rate is 500. both balanced. 500 - 500 = 0, zero growth in population.
Which of these statements is true of using melting and boiling points to identify a substance? Text to speech A:A. It is an effective method to identify gas molecules. B:B. It is the most affordable way to identify a substance. C:C. It is a property that changes based on the amount of a substance you have. D:D. It is a property that does not change regardless of the amount of a substance you have.
Answer:
D:D. It is a property that does not change regardless of the amount of a substance you have.
Explanation:
Melting and boiling points are two chemical properties of a substance. These are used to identify whether a substance is solid, liquid, or gas.
The melting point is the temperature at which solid-state changes into liquid state. The boiling point is defined as the temperature at which liquid changes to gas.
The melting and boiling point are intensive properties that are independent of the amount of substance to be identified.
Hence, the correct answer is "D. It is a property that does not change regardless of the amount of a substance you have."
Mendel bred an unknown plant displaying a dominant phenotype with an individual showing the recessive phenotype; then, he analyzed the offspring to determine the unknown genotype. This experiment is called a(n)
What Mendel did according to the illustration would be called test-crossing.
Test-crossingIn genetics, test crossing is a procedure through which the zygosity of an individual can be determined - whether it is homzygous or heterozygous.
Test crossing requires that an organism who displays a dominant trait but whose zygosity is unknown is crossed with another organism of the same species but who displays the recessive version of the same trait.
By so doing and using the knowledge of probability, the resulting offspring from the cross will be used to determine the zygosity level of the parent.

Which statement is NOT an accurate description of a cell membrane? a Regulates what enters and leaves the cell. b Responsible for the formation of ATP c Provides protection and support for the cell. d Flexible and made up of smaller molecules such as lipids and proteins
Answer:
The correct answer is - b. Responsible for the formation of ATP
Explanation:
The cell membrane is the outer membrane of all types of the cell including eukaryotic, and prokaryotic cell. The cell membrane surrounds the cytoplasm and cell organelles.
The cell membrane is made up of phospholipids that have a hydrophilic and hydrophobic region in the lipid bilayer. The main function of the cell membrane is to protect the cell, provide support, and regulation what enters and leaves the cell. ATP formation is not produced by the cell membrane.

The relationship between the amount of energy available for use and the amount of entropy in a food chain differs between trophic levels. Why would the amount of entropy increase from one trophic level to another in a food chain or energy pyramid? a. The available energy from one trophic level to another increases b. Energy is lost at each level as heat, which increases randomization c. The amount of biomass decreases from one trophic level to another d. The available energy at each level may either increase or decrease, creating randomization.
The quantity of entropy in a food chain differs among trophic tiers the best choice is "B" strength is misplaced at every degree as heat, which will increase randomization.
The amount of entropy is the energy required for the movement from one trophic level to another and when strength is misplaced at every degree as heat, which will increase randomization then the amount of entropy increase from one trophic level to another in a food chain or energy pyramid.
What are the ten in line with the cent regulation of strength?
The 10% Rule shows that after strength is flowing in surroundings from one trophic level to the next, the best ten in line with cent of the strength could be exceeded. The trophic level is the placement of an organism in a food chain or strength pyramid.
Thus, strength is misplaced at every degree as heat, which will increase randomization.

1. For the following decide if they are density dependent (size matters) or density independent (size doesn’t matter will happen anyway) (Population Growth slideshow 16/17)
a. Weather (snow, rain, drought)
b. Predation
c. Competition
d. Natural disasters (hurricane/tornado/earthquake/floods/drought)
2. Define Carrying capacity (Population Growth slideshow 10-14)
3. HIghlight the factors that would be affected if a population would be near carrying capacity: unlimited
food, limited space/shelter (habitat), unlimited water, disease, predation, competition (Population

7. Be able to apply the 10% rule when given a pyramid or a food chain/web (ecology slideshow 20-23) Remember just move the decimal point 1 time for each step. The other 90% of energy is lost as heat energy.
In the following food chain what amount of energy does the snake have if the seed starts with 29345 kcal of energy?
Seed→mouse→snake→ hawk.
Remember the further away from the plant (autotroph) the less energy you have. Bacteria feed on anything that dies.
8. What type of energy is lost during food chains/webs? (HInt 10% rule, plants give energy to animals then they give energy to bacteria when they die (bodies decomposed))
1) DI: a,d,g. DD:b,c,e,f. 2) K is a constant equal to the population size at the equilibrium. 3) 2,4,5,6. 4) 100. 5) Prey population size is followed by predator population size. 6) B: a,c,d,h. A: b,e,f,g,i. 7) 293.45 kcal. 8) caloric energy.
1) What are density dependent or independent factors?
These are limiting factors that affect the carrying capacity.
Density-dependent, DD, factors are a result of the population size
Density-independent, DI, factors do not depend on population size. These are human impact, weather, or natural disasters
a. Weather (snow, rain, drought) → Density-independent
b. Predation → Density-dependent, DD
c. Competition → Density-dependent, DD
d. Natural disasters → Density-independent, DI
e. Food availability → Density-dependent, DD
f. Disease → Density-dependent, DD
g. Human activities (deforestation, dams) → Density-independent, DI
2) What is carrying capacity?Carrying capacity (K) is the maximum point at which the environment can support a growing population. It is a constant equal to the size of the population (N) at the equilibrium point when the natality rate and the mortality rate get equal to each other.
3)
unlimited food → No, because it is unlimitedlimited space/shelter (habitat), → Yes, because it is limitedunlimited water → No, because it is unlimiteddisease → Yes, because it is dense-dependentpredation → Yes, because it is dense-dependentcompetition → Yes, because it is dense-dependent4) 100 is the number of individuals in a species that equals the carrying capacity.
When the population reaches 100 individuals, K = N = 100, it reaches an equilibrium. If it keeps growing N = 101, it must decrease dropping to N = 99.When N < 100 it can still grow. 5) What is the predator-prey model?When a prey lives in the ideal environment with no predators, it shows an exponential growth rate.
Prey can grow, develop, and reproduce, increasing its population size.
But when predators appear, the more available items, the more predator there will be.
The predator population increase in size, decreasing the prey populations size. So there are fewer available items to prey on.
The prey population also affects the predator population. The predator depends on the prey density. The more predators there are, the fewer prey there will be left.
The predator population decreases exponentially due to the item's lack. The predation rate depends on density as well as natality and mortality rates.
Predatory/prey graph,
The graph shows the variation in population size of predators are preys with time. For a better understanding look at the attached files.
1. prey population increases in size → red line
2. predator population increases in size → green line
3. prey population decreases in size → red line
4. predator population decreases in size → green line
6) What are biotic and abiotic factors?The ecosystem is composed of living and non-living things that interact and depend on each other.
Abiotic factors are physical and chemical things of the ecosystem that do not include any living elements. Biotic factors are all the living components in the ecosystem.a. Bacteria → Biotic, B
b. pH level → Abiotic, A
c. fungus → Biotic, B
d. plants → Biotic, B
e. oxygen availability → Abiotic, A
f. Sunlight → Abiotic, A
g. water → Abiotic, A
h. animals/parasites/predators → Biotic, B
i. pollution → Abiotic, A
7) What is the 10% rule?From the energy that reaches the earth's surface, only 0.1 or 1% is taken by autotroph organisms. This small percentage of energy flows through all organisms in the ecosystem until it dissipates in the environment.
The 10% rule states that only about 10% of the energy stored as biomass at one trophic level, ends up as biomass at the next trophic level.
The progressive reduction of energy determines the number of trophic levels (4 or 5).
Seed → 29345 kcal of energy
⇒ 10% of 29345 kcal is 2934.5
The mouse gets 2934.5 kcal of energy
⇒ 10% of 2934.5 kcal is 293.45
The snake gets 293.45 kcal of energy
⇒ 10% of 293.45 kcal is 29.345
The hawk get 29.345 kcal of energy.
According to these calculations, the snake have 293.45 kcal of energy.
8) What type of energy is lost during food chains/webs?Producers receive luminous energy from the sun, and they store 1% of it.
Consumers along the trophic web receive 10% of chemical energy from the direct anterior link. The remaining energy is lost as caloric energy.
The correct answer is caloric energy.
