What structures have parasite worms lost? What structures/organs are expanded?
Explanation:
Something that is lacking, is a circulatory system. Instead of a typical circulatory system flatworms exchange oxygen with the air outside through diffusion. This is the process by which gases will pass through a membrane from an area of high concentration to an area of low concentration.

Explain what causes a muscle to go into rigor mortis. Your answer should include the circumstances which cause it, as well as why those circumstances cause the effect (what is happening in the muscle at a molecular level which causes the stiffness).
Explanation:
Rigor mortis develops as the body's energy source (adenosine triphosphate [ATP]) is depleted. Muscle fibers require ATP for relaxation; once depleted, actin and myosin proteins remain complexed, resulting in stiffening of the muscles..

If u looked at a SA cells and cardiac muscle cells under a microscope, do u think they would look the same or different from each other? Explain ur reasoning HELP MEE PLSSSSS
Answer:
They look a little bit different. SA cells contain fewer mitochondria, fewer myofibers, and a smaller sarcoplasmic reticulum. This means that the SA node cells are less equipped to contract compared to the atrial and ventricular cells.

what are the the four main categories of organic macromolecules ?
Answer:
There are four major classes of biological macromolecules (carbohydrates, lipids, proteins, and nucleic acids), and each is an important component of the cell and performs a wide array of functions.
Four main categories of organic macromolecules are as follow:
carbohydratelipidsproteinsnucleic acidWhat are macromolecules?Macromolecules are polymers containing long chains of molecular sub-units known as monomers. These play an important role in biophysical processes and composed of thousands of atoms that are covalently bonded.
Carbohydrate is a biomolecule having carbon, hydrogen and oxygen atom.It is the main source of energy of the body.
Lipids are macromolecules that are insoluble in water and the main function is to serve as structural component of cell membrane.
Proteins are macromolecules that are extremely complex in structure and made up of amino acid residues joined by peptide bonds.
Nucleic acids are biopolymer macromolecules and composed of nucleotide. The function is to carry genetic information which helps to make RNA.

A cluster of cases of legionellosis have occurred in your neighborhood. People with the illness have cough, fever, shortness of breath, chest pain and sometimes diarrhea. The illness is caused by the bacterium Legionella pneumophila, a facultative intracellular parasite that survives in certain ameba. The organism has an absolute requirement for L-cysteine. Typically, the organism is grown on buffered charcoal yeast extract (BCYE) agar. In some labs, samples containing suspected L. pneumophila are cultured on traditional BCYE medium as well as BCYE medium lacking L-cysteine. How would L. pneumohila be identified in this situation
Answer:
The correct answer is - comparing the presence of an essential component of the L. pneumophila that is cysteine.
Explanation:
As we know that L-cysteine is essential for the organism L. pneumophila to grow its colonies. The identification is easy in this situation by comparing the two cultured on the traditional BCYE medium and BCYE medicum without L-cysteine.
Colonies that grow on traditional BYCE medium are likely L. pneumophila as they required L-cysteine but not on BYCE medium lacking cysteine.

Which of the following would be affected when a protein is denatured?
a.) amino groups
b.) primary structure
c.) side chains
d.) tertiary structure
"b" why because primary structure needs protein and if protein denatured,primary structure will affected instantly!
#followandheartallmyquestion
When a protein is denatured by chemical, heat or other substances, the primary structure remains intact. Hence, the correct answer would be the tertiary structure.
Denaturation of proteins generally causes the breakage of weak bonds on which the folding and the entire protein structure is built. When this happens:
the peptide bonds between the component amino acids remain intact. Hence, the primary structure is conservedthe destruction of other bonds means that the secondary and tertiary structures are affected.Agents that are capable of denaturing proteins include high temperature, changes in acidity/basicity, UV radiation, high concentration of salts, and so on.
The correct answer as to which would be affected when a protein is denatured in this case would, therefore, be the tertiary structure.

In a separate study, 68 rock pocket mice were collected from four different, widely separated areas of dark lava rock. One collecting site was in Sonora, Mexico. The other three were in Chihuahua, Mexico. Dr. Nachman and colleagues observed no significant differences in the color of the rocks in the four locations sampled. However, the dark-colored mice from the three Chihuahua locations were slightly darker than the dark-colored mice from the Sonora population. The entire Mc1r gene was sequenced in all 68 of the mice collected. The mutations responsible for the dark fur color in the Sonora mice were absent from the three different populations of Chihuahua mice. No Mc1r mutations were associated with dark fur color in the Chihuahua populations. These findings suggest that adaptive dark coloration has occurred at least twice in the rock pocket mouse and that these similar phenotypic changes have different genetic bases.

How does this study support the concept that natural selection is not random?
Answer:
The study supports the concept that natural selection is not random because in different areas with the same or very similar environmental characteristics, the same phenotype was produced by different types of mutations.
Explanation:
All of the sampled animals are inhabiting dark substrate. Probably animals needed to camouflage to survive. Natural selection must have driven them to produce dark color, similar to the substrate color. So animals from the different regions suffered different mutations that drove them to have almost the same dark fur color. The environmental condition is favoring the same phenotype.
Which term indicates that a single gene has two or more alleles present in a population?
A. Genotype
B. Point mutation
C. Polymorphism
D. Pleiotrophy
Genetic polymorphism is the existence of multiple alleles of a single gene.
What are genes?Genes are regions of DNA which code for a particular protein or any other gene product.
Genes can exists as a single copy or as multiple copies.
Alleles are alternate forms of a particular gene.
A single gene that has two or more alleles present in a population is known as genetic polymorphism.
Therefore, multiple alleles of a single gene is known as genetic polymorphism.

The first stage of the cell cycle during which the cell matures and prepares to divide and copies
its DNA; The stage the cell stays in the most?
The cell multiplies and creates a copy of its DNA during interphase. In the mitotic (M) phase, the cell divides into two new cells by dividing its cytoplasm and DNA into two sets.
What is the main role of interphase stage of cell cycle?A cell consumes the bulk of its time in what is known as interphase, where it creates, duplicates its chromosomes, and acquires available to split. The cell then moves interphase, goes direct mitosis, and completes dividing.
The cell multiplies and the nuclear DNA is duplicated during interphase. The mitotic phase immediately follows interphase.
Chromosomes that have been duplicated are separated and distributed across daughter nuclei during the mitotic phase. Usually, the cytoplasm is divided as well, producing two daughter cells.
Therefore, The first stage and the stage the cell stays in most is Interphase.
