Why does the us have limited government
Answer:

why does the structure of a protein depend on the sequence of the DNA?
Answer:
Explanation:
The Rules of Protein Structure. The function of a protein is determined by its shape. The shape of a protein is determined by its primary structure (sequence of amino acids). The sequence of amino acids in a protein is determined by the sequence of nucleotides in the gene (DNA) encoding it.

How does pollution affect marine life? a. Pollution causes a decrease in phytoplankton populations and therefore a decrease in the occurrence of algal blooms. b. Pollution causes destruction of coral reefs, which are important sources of shelter and breeding for marine animals. c. Soaps, detergents, and plastics in the ocean decrease the acidity of ocean water, leading to a decrease in carbonate levels. d. Pollution affects organisms close to the shoreline, but does not affect marine organisms far from the shore.
Answer:
b
Explanation:
According to the question, Pollution causes destruction of coral reefs, which are important sources of shelter and breeding for marine animals.
How does pollution affect marine life?Fish, seabirds, sea turtles, and marine mammals can become entangled in or ingest plastic debris, causing suffocation, starvation, and drowning.

Compare and contrast between a human and an alligator life cycle.
Answer:
The human body constantly develops and changes throughout the human life cycle, and food provides the fuel for those changes. The major stages of the human lifecycle include pregnancy, infancy, the toddler years, childhood, puberty, older adolescence, adulthood, middle age, and the senior years.

Which of the following groups of organisms uses sunlight to convert carbon dioxide and water into sugar and oxygen?
a. producers
b. decomposers
c. carnivores
d. herbivores
The group of organisms which uses sunlight to convert carbon dioxide and water into sugar and oxygen are producers. Thus, the correct option is A.
What are Producers in the ecosystem?Producers are any kind of green plants present in the ecosystem. Green plants make their own food by using the sunlight (solar energy) and carbon dioxide gas from the atmosphere with the energy to make sugar. The plant uses this sugar (carbohydrate), also called as glucose to make many different products, such as wood, leaves, roots, and bark.
This process through which plants produce their food is called photosynthesis. Photosynthesis occurs only in the plants which have chlorophyll pigment (chloroplast).
Therefore, the correct option is A.

what are the types of cell ?
Cell is the small unit of all living organism, observed in animal, plant, microbes etc; cells are unicellular in nature like bacteria cell, where as some are multicellular in nature like all higher eukaryotic organisms such as plants and animal cell.
The simplest form of cells are prokaryotic cells have a cell membrane, cell wall and cytoplasm where all of the metabolic processes occur, ribosomes needed for protein synthesis occur, and nucleoid which carry genetic information, reproduce by binary fission.
The eukaryotic cells contain a complex organization where it contain cell membranes, cytoplasm, ribosomes, and nucleus a house of DNA, rough endoplasmic reticulum , smooth endoplasmic reticulum for lipids, Golgi apparatus responsible for protein sorting and exporting.
It has mitochondria power house house of the cell, a cytoskeleton responsible for structure and passes information, and lysosomes or peroxisomes for waste digestion, vacuoles for water storage, chloroplasts for photosynthesis.

What is the role of enzymes in the DNA replication process?
A. Enzymes read the DNA code and build a new DNA molecule from scratch.
B. Enzymes link together to form a template for a new DNA molecule to be built.
C. Enzymes split the DNA molecule into two rails and then transport corresponding nitrogenous bases to each rail.
D. Enzymes link adjacent nucleosides together, becoming an integral part of the structure of the new strands of DNA.
Answer: C. Enzymes split the DNA molecule into two rails and then transport corresponding nitrogenous bases to each rail.
Explanation: This would be known as the double helix because it is being split.
Different enzymes are involved in DNA replication: DNA polimerase, primase, helicase, ligase, and topoisomerase. The correct option is C. Enzymes split the DNA molecule into two rails and then transport corresponding nitrogenous bases to each rail.
---------------------------------------------
DNA Replication starts in some specific place named replication origin.
Helicase
This is the first enzyme that works in the replication origin. It separates the DNA into two strands allowing the replication forks to advance by unwinding the DNA. It breaks hydrogen bonds between nitrogenated bases pairs.Topoisomerase impedes the DNA double helix near the replication forks to get too coiled when the DNA is opening.
DNA polymerase III
This enzyme is responsible for DNA elongation. It is in charge of adding nucleotides to the growing chain, from 3' to 5' extremes. It includes only nucleotides that complement the original strand. They need to recognize a primer to begin.Primase is in charge of synthesizing primers.
DNA polymerase I eliminate ARN primers and substitute them with DNA.
DNA ligase seals the gaps that remain after replacing the primers.

is chlorine gas a polar or nonpolar covalent bond
Pretty sure its non-poaler (definitly sure) :)
Answer:
Explanation:
Covalent bonds are very similar to chlorine gas. Which is also known as (C12). Both of these atoms share and hold tightly onto their electrons.
The hydrogen atom has a positive charge becauseIt cannot hold as tightly to the negative electron bones. Covalent molecules with this type of uneven charge distribution are polar.

Homologous chromosomes are chromosomes that are the same? true or false
Answer:
False
Explanation:
The 22 pairs of homologous chromosomes contain the same genes but code for different traits in their allelic forms since one was inherited from the mother and one from the father. So humans have two homologous chromosome sets in each cell, meaning humans are diploid organisms.
