Which are required for natural selection to occur?
inheritance, isolation, adaptation
variation, overpopulation, adaptation
isolation, overpopulation, speciation
variation, inheritance, speciation
Answer: B
Explanation:
Natural selection is a mechanism of evolution which was given by Charles Darwin. According to natural selection, individuals with heritable traits which favor their reproductive success as well as survival are selected by nature.
For natural selection to take place, there should be variability as well as higher reproductive success . Eventually natural selection causes individuals to become adapted to their environment (i copied the answer from someone else but here you go so you don't have to search for them)

Explain the differences in the population growth patterns of the two Paramecium species. What does this tell you about how Paramecium aurelia uses available resources?
Answer:
The data in the question is missing, luckily, I found a matching data:
The following data is the results of a trial of paramecium growth over 16 days, the numbers going in order horizontally P. aurelia grown alone, cells/mL, P. caudatum grown alone, cells/mL, P. aurelia grown in mixed culture, cells/ mL, P caudatum grown in mixed culture, cells/mL.
Day O 1 1 1 1
Day 2 4 5 3 5
Day 4 27 15 16 9
Day 6 43 24 31 10
Day 8 54 28 38 7
Day 10 47 28 45 4
Day 12 48 28 46 1
Day 14 49 28 50 0
Day 16 49 28 47 0
Answer:
The pattern of growth tells us that individual Paramecium aurelia uses a smaller amount of resources for growth compared to P. caudatum, hence the greater number of species after culturing.
Explanation:
When bacteria species are cultured in an appropriate growth medium, they utilize the nutrient in such media for their growth, and the growth becomes exponential until there are not enough resources to sustain a continuous growth of the organism, then the growth pattern starts to show a decline which is seen in the P. caudatum species quickly because the organism use up more resources compared to the Paramecium aurelia species.
a pyramid of energy for this ecosystem would look more like the pyramid of numbers or biomass
Answer:
biomass; numbers
Explanation:
For Savvas Realize
The pyramid of energy for biomass would look more like the pyramid of numbers.
What is pyramid of energy?Primary producers occupy the highest biomass in a pyramid of energy. In general, only 10-20% of biomass is transferred from one trophic level to the next.
In general, biomass pyramids are upright because biomass decreases as trophic level increases.
Ecological pyramids are a method of visualizing a food chain, using either the mass of organisms or the total population of organisms at each stage of the food chain.
Pyramids of biomass are always of the "classic" shape, whereas pyramids of numbers can be inverse or have levels of varying width.
Thus, the pyramid of numbers has similarity with that of biomass, but pyramid of biomass is more accurate than that of the number.

Which of the following is a function of the cell membrane?
keeps the cell wall in place
breaks down lipids, carbohydrates, and proteins from foods
stores water, salt, proteins, and carbohydrates
regulates which materials enter and leave the cell
Answer:
Regulates which materials enter and leave the cell.
Explanation:
I'm not 100% sure on this but I think cell membranes provide protection for the cell as well as regulating what enters and leaves the cell.
Cell membrane regulates which materials enter and leave the cell. So, the correct option is (D).
What is Cell membrane?Cell membrane is also called plasma membrane which is a semipermeable membrane made of lipids and proteins and found in all types of cells in humans, animals, plants, bacteria etc.
The cell membrane is the outermost boundary of animal cells. Cell membrane has many functions which are as follows:
Maintaining integrity within the cell.Providing support and preserving the shape of the cell.Through balancing endocytosis and exocytosis, it aids in cell growth regulation.Cell signaling and communication are also facilitated by cell membranes.Cell membrane functions as a selectively permeable membrane which enable only certain chemicals to enter the cell.
Thus, cell membrane regulates which materials enter and leave the cell. So, the correct option is (D).

Cells can respond to many different ligands. Some of these ligands may cause intracellular signaling cascades that converge on the same protein or enzyme. This phenomenon is called
Answer:
Signal transduction
Explanation:
Ligand forms complexes with substance and a ligand protein binds to a target site on protein and produces a signals on binding to it.
Signal transduction is the process by which signals both physical and chemical are transmitted through a cell via a series of molecular events especially protein phosphorylation catalyzed by protein kinases that results in a cellular response.
Receptors are proteins that detect stimuli. The changes that comes from ligand binding a receptor give rise to a biochemical cascade.

Explanation:
What would most likely be produced when a cell with eight chromosomes undergoes mitosis?
Answer: two cells with eight chromosomes each
Explanation:
A diploid cell that enters mitosis with eight chromosomes will divide to produce two diploid daughter cells, each of which also has four chromosomes.
What is mitosis?
Mitosis is the process by which a cell replicates its chromosomes and then segregates them, producing two identical nuclei in preparation for cell division. Mitosis is generally followed by equal division of the cell's content into two daughter cells that have identical genomes
it is also known as equational division.
so, if a cell with 8 chromosome undergoes mitosis , it will produce two daughter cell with four chromosome.

what will happen to the concentrations of atp, nadph, and sugar when you add diuron.
Answer: its decreas for all of them
Explanation:
Cuz I did it lol
The application of diuron decreases the activity of ATP, NADPH, and sugar production.
What is diuron?Diuron is a powerful herbicide and algaecide that blocks the natural process of photosynthesis and inhibits the weed's ability to convert light energy into chemical energy.
It stops the process of photosynthesis by stopping the creation of oxygen and blocking the transfer of electrons from photosystem II in plants, which stops the electron transport chain from working properly.
In the long run, this causes a reduction in the amount of ATP, NADPH, and sugar that plants produce.

A large amount of energy is needed to produce food. In all parts of the world, the energy used to process, distribute, and cook food is greater than the energy used to grow it. In the United States, it is estimated that every Calorie of food on our dinner tables has required 9 Calories of energy to get there. Half a Calorie accounts for the energy used on the farm. The other 8.5 Calories account for energy for processing, packaging, distribution, and cooking. In rural India, twice as much energy goes into cooking a kilogram of rice as was invested in producing it. Energy shortages, such as a shortage of wood for cooking, have caused environmental problems such as deforestation. In poor countries, cooking may require more energy than is used by transportation, heating, and all other uses for energy combined.
1. According to the passage, which of the following statements about food is true?
A. Most of the energy invested in food production goes into distributing the food.
B. More energy is used to grow food on the farm than is used to cook the food.
C. Most energy used to produce food goes into processing, distributing, and cooking the food.
D. In developing countries only, cooking food requires more energy than growing food does.

Human activities and natural events can have a large effect on populations, biodiversity and ecosystem processes. How does the growth of the human population into rural areas affect the environmental quality of the native ecosystem?
Answer: human population growth in rural areas creates additional waste that is put back into the environment and lowers environmental quality.
Explanation:
Increase in human population in the rural areas leads to an increase in ;
Environmental pollution through indiscriminate waste disposal.As the human population grows the need to feed the growing population will increase as well as the amount of waste and all these will have a direct negative effect on the environment because the volume of waste in the environment will increase if not properly managed.
Human activities such as ; the use of chemicals for fishing and planting also pollutes the waters and land which are the vital part of the environment and the excessive burning of fossil fuels pollutes the atmosphere as well.
Hence we can conclude that Increase in human population leads to an increase in ; Environmental pollution through indiscriminate waste disposal.
