You are trying to help a friend sort some specimens in her lab. She collected organisms from a lake and forgot to label the sample with the part of the lake from which they were taken. Please select the item below that is correctly matched with its collection zone.
a. periphyton labeled "open water"
b. phytoplankton labeled "littoral zone"
c. anaerobic bacteria labeled "limnetic zone"
d. zooplankton labeled "limnetic zone"
e. cattails (emergent plants) labeled "profundal zone"
Answer:
D. zooplankton labeled "limnetic zone"
Explanation:
the zone called the limnetic zone is a well lighted and open zone in a body of fresh water such as the lake or the pond. this zone has the plankton in dominance. both the phytoplankton and the zooplankton. plankton play an important role in the food chain.
zooplankton are primary consumers in this limnetic zone. zooplankton consists of rotifers and copecod
Bear in mind the biological definition of a species and also the appearance and distribution of the named populations of Ensatina. Which populations could be considered a species separate from E. e. eschscholtzii?
Answer:
E.e. oregonesis
E.e. platensis
E.e. xanthoptica
E.e. croceater
E.e. eschscholtzii
E.e. klaubori
Explanation:
The species mentioned above are probably separate species from E.e. eschscholtzii, which arose through ring speciation that occurs when a species is geographically distributed in a circular pattern. After this distribution, geographic isolation occurs, causing individuals in each different region to evolve differently, becoming other species, even reaching the point where it is not possible to cross them.
Punnet square? Someone know who to do this
Answer:
Punnet squares are basically how you can somewhat "predict" the outcome of gene pools.
Explanation:
As you can see, the capital letters (RY) are dominant alleles meaning they will be the trait that shows no matter what. the lower case letters (ry) show recessive traits and will only show if paired with another recessive gene.
Genotype is the actual makeup so the letters. (Rr, Ry, ry... etc.)
Phenotype is the trait that shows such as brown hair, blue eyes, etc.
Frequency is just how many times the gene shows up and put as a fraction or percent.

One strand of DNA nucleotides is read as 5' - GCATATTG - 3'. What would
be the complementary strand?
Answer:
The correct answer would be: 3' - CGTATAAC - 5'
Explanation:
DNA molecule is a double-stranded molecule structure that has two distinct nucleotide chains joined together with hydrogen bonds between the nitrogenous bases of each strand. Adenine binds with thymine and cytosine binds with guanine by hydrogen bonds always in complementary strands.
These strands are complementary to one another as they have complementary bases in the complementary strand of one nucleotide chain of DNA. So,
5' - GCATATTG - 3' - DNA nucleotide of one strand
3' - CGTATAAC - 5' complementary strand

DNA consists of ____ chains(s) of subuints, and RNA consists of _____ chain(s).
DNA has two chains of subunits and RNA has only one chain of subunits.
What are the differences between DNA and RNA?
DNA or Deoxyribonucleic acid is a nucleic acid structure. Its function is to work as an original blueprint or the basic code for protein synthesis. A DNA molecule has deoxyribose sugar, it has lost an oxygen molecule from the 3' carbon.
It also has phosphates and nitrogenous bases like adenine (A), guanine (G), cytosine (C) and thymine (T) in a unique sequence. These sequences form two chains which are intertwined to form a double helix.
Ribonucleic acid or RNA is also a nucleic acid. This directly takes part in protein synthesis. It is an important nucleotide and has nucleic acid in long chains that are present in all living cells. It has ribose sugar. It has the same nucleotides as DNA except for uracil (U) replaces thymine (T).
The main role of RNA is to act as a messenger. It gets instructions from DNA and uses them for controlling protein synthesis. This is present in a single chain.
Therefore, DNA has two chains of subunits and RNA has only one chain of subunits.

Explanation:
Explain the basis for the great diversity of proteins in living organism.
Answer:
Explanation:
Protein functions are so diverse because of the many unique three-dimensional structures protein polymers form. Despite such variety, proteins also share several specific structural characteristics in their monomers, the amino acids. Structural similarities among amino acids make protein synthesis a uniform and regulated process; however, each amino acid contains a unique structural component as well. Specific differences between each amino acid interact to create unique three-dimensional protein structures. Combined, the similarities and differences between amino acids explain how cells can build a diverse pool of proteins from the same set of building blocks. Protein synthesis involves building a polymer of amino acids with complex three-dimensional structure. Dehydration synthesis forms a peptide bond between amino acids and releases a water molecule.

Fifty years ago, bed bugs were nearly eliminated in the United States by using of pesticides like DDT. Today bed bugs are back in beds and theaters. DDT is no longer used due to environmental issues. Pyrethrums are currently the top choice for bed bug infestations. Pyrethrums are especially useful to us because they generally have a stronger effect on bugs than on humans and animals.
Some bed bugs had mutations in their genetic code which allowed them to survive the chemical pesticide and they produced chemically resistant offspring. How can this be explained?
Question 5 options:
bed bugs chose other bugs to partner with who had the mutation
mutations involved in the genetic variation of the bugs were chosen by them
bed bugs chose other bugs to partner with who had no mutations
mutations involved in the genetic variation of the bugs are random

why do the other planets take longer to orbit the Sun than the inner planets do
Answer:
Outer planets take longer to orbit than inner planets because of the greater distance they need to cover. They also are further from the sun weakening the power of the suns gravitational pull which causes then to orbit slower.
Explanation:

Answer:
Because there are outter planets

What features of integrated pest management make it a good approach to preserving ecosystems?
Answer:
Allowing a small but controlled portion of a pest population to remain does less damage to ecosystems, soils, water, and air. Another feature of IPM would be making a habitat more complex, such as mazes, so it can slow the spread of parasites. No-till or low-till agriculture is another feature of IPM because this helps natural enemies of some pests to build up in the soil, whereas plowing destroys the habitats of these enemies.

Two heterozygous parents have ___________chance of contributing one of their alleles to each offspring
Answer:
Two heterozygous parents have a 50% chance of contributing one of their alleles to each offspring.
Explanation:
Individuals who are heterozygous for a specific trait have two different alleles in the gene that determines that trait. This characteristic makes their chances of contributing each of their alleles to the offspring 50%.
The alleles of a gene are distributed in the gametes by the process of meiosis, which results in daughter cells with half the genetic charge, so each gamete can only have one copy of the allelic pair of a gene.
On the other hand, if an individual has two equal alleles for a characteristic in a gene, he has a 100% chance of passing that allele on to his descendants.
