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.

Answer:

The correct answet is -

1. C. Most energy used to produce food goes into processing, distributing, and cooking the food.

2. D. Gathering sufficient wood to cook food has led to deforestation.

Explanation:

In the given passage, the author stated the fact that the most of the energy used in the production of the food is actually invested in the processing, transportation, packaging and cooking the food.

In this passage it is also stated that the cooking requires twice much energy in cooking the food than growing in rural area and in poor countries only cooking itself requires most of the energy of the production of the enrgy. In this passage, there is nothing about the wood and deforestation.

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.

The malleus, incus, and stapes are the smallest bony ossicles of the middle ear, along with the tympanic membrane. Therefore, the statement is true.

Ossicle is a colloquial term referring to a tiny bone or bony structure. in particular, any one of the three tiny bones that make up the middle ear, which are the malleus, the incus, and the stapes.

The long process of the incus is bowed near its lower end and carries a little knoblike bone that is loosely jointed to the head of the stapes, which is the third and smallest of the ossicles.

A bone in the shape of a horseshoe is the one that is responsible for sending the sound wave to the brain. Because to its length of about 2-3 millimeters (or 0.1 inch), it is regarded to be the smallest bone.

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).

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:

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).

The application of diuron decreases the activity of ATP, NADPH, and sugar production.  

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.

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.

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 ;

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.

Answer: TAACTG

Explanation: Remember the base pairing rules: cytosine with guanine and adenine with thymine. To compliment the given strand, you'd have to choose the base that would pair with each individual nucleotide.

For example,

The pair to ACCTGAC  would be TGGACTG.

Hope this helps,

Lacia

DNA bases for the strand ATTGAC is TAACTG which is the complementary base pairing rule adenine pairs with thymine and cytosine pairs with guanine.

Thymine, adenine, guanine, and cytosine are the four nitrogenous bases found in DNA. Adenine and thymine are joined by two hydrogen bonds, whereas guanine and cytosine are joined by three hydrogen bonds.

Base pairing that is complementary is what this is to create a DNA molecule, the DNA sequence of a gene must be copied, bases for the strand ATTGAC is TAACTG.

RNA polymerases, which join nucleotides to create an RNA strand, carry out transcription (using a DNA strand as a template).

Therefore, DNA bases for the strand ATTGAC are TAACTG due to complementary base pairing.

Answer:

biomass; numbers

Explanation:

For Savvas Realize

The pyramid of energy for biomass would look more like the pyramid of numbers.

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.
