Which of the following is the best definition for a macromolecules
The best definition for a macromolecules is the most abundant elements found in living cells. The correct option is d.
What are macromolecules?
A macromolecule, such as a protein or nucleicacid, is a very large molecule that is important in biophysical processes.
It is made up of thousands of atoms that are covalentlybonded. Many macromolecules are polymers composed of smaller molecules known as monomers.
Macromolecules are essentially polymers, which are long chains of molecular subunits known as monomers.
Long polymers are found in carbohydrates, proteins, and nucleic acids. They are classified as macromolecules due to their polymeric nature and large size.
Macromolecules are made up of monomers, which are single units joined together by covalent bonds to form larger polymers. The most abundant elements found in living cells are the best definition for macromolecules.
Your question seems incomplete, the missing options are:
a. a trace element
b. a vitamin
c. an organic molecule necessary for life
d. the most abundant elements found in living cells
There are no answers to choose from.
However, the prefix macro- means big, so the word macromolecule means large molecule. Macromolecules are also known as the molecules of life, they all contain carbon. The four macromolecules are carbohydrates, proteins, lipids, and nucleic acid. Carbohydrates are used as a quick energy source, they can be broken up into monosaccharides, dsaccharides, and polysaccharides. Proteins are used as catalyst to help speed up chemical reactions. Lipids are also known as fats, they can either be saturated or unsaturated. Nucleic acids contain information.
Bacteria and fungi are found in all ecosystems on earth answer
The answer is; true
These microbes are usually adapted to their environment and this is why they are found in virtually all ecosystems. You will find bacteria even at the bottom of deep ocean beds deep and in geothermal vents, hypersaline water and very cold regions (such as polar regions). Fungi which vary widely in size from microscopically small to the largest organisms such as mushrooms are also found in virtually all environments on earth. They are nonetheless different species of these groups adapted to their environments.
Which of the following domains contains the common advanced plants, animals, and fungi?A. Protist B. Bacteria C. Eukarya D. Archaea
It would be "C.Eukarya" (I don't speak English, I hope it's okay)
What are the only two mammals that lay eggs?
The platypus and the echidna.
1. Duck-billed platypus 2. spiny anteater
Most ocean water is located in which zone? A. deep zone B. surface zone C. transition zone D. mixed zone
Which is associated with the reproductive system?a the seminal vesicles b the fallopian tubes and ovaries Cthe production of gametes and sex hormones d All of the above are associated with the reproductive system.
It is D. I’m 97% sure hope this helps :)
Answer is D All of the above are associated with the reproductive system
In chickens, comb shape is determined by alleles at two loci (R, r and P, p). A walnut comb is produced when at least one dominant allele R is present at one locus and at least one dominant allele P is present at a second locus (genotype R_ P_). A rose comb is produced when at least one dominant allele is present at the first locus and two recessive alleles are present at the second locus (genotype R_ pp). A pea comb is produced when two recessive alleles are present at the first locus and at least one dominant allele is present at the second (genotype rr P_). If two recessive alleles are present at the first and at the second locus (rr pp), a single comb is produced. A walnut is crossed with a pea chicken and the offspring consists of 3/8 walnut, 3/8 pea, 1/8 rose and 1/8 single. What are the probable genotypes of the parents
RpPp x RpPp
For the recessive trait to be expressed, both parents should have at least 1 allele for the recessive trait. Now you can see that both recessive traits were expressed in at least one of the off-springs, this means that both parents had the allele for each recessive trait.
