Pls answer will mark brainliest to first person! I will report if it does not relate. Research an internal organism that has adapted over time to allow the species to perform specialized functions. Describe how the internal structure helps the organism survive in its ecosystem.
Answer:
An organism that was adapted over time to perform specialized functions is the saddleback tortoise which adapted slowly over time. Saddleback tortoise have shells that rise in front, like a saddle. This adaptation makes it easier for them to lift their heads high to eat tree cactus. This helps the tortoise survive by letting it reach a food source and not starve.

Antibiotics can be used to kill the specific pathogenic bacterium, Mycobacterium tuberculosis, that causes tuberculosis. The appearance of antibiotic-resistant strains has made it more difficult to cure M. tuberculosis infections. These antibiotic-resistant bacteria survive and pass on the genes to their offspring, making the resistant phenotype more common in the population. DNA analysis indicates that the genes for antibiotic resistance are not normally present in bacterial chromosomal DNA. Which of the following statements best explains how the genes for antibiotic resistance can be transmitted between bacteria without the exchange of bacterial chromosomal DNA
a. The antibiotic-resistant bacteria release a hormone that signals neighboring bacteria to become resistant
b. The genes for antibiotic resistance are located on a plasmid that can be passed to neighboring bacteria.
c. The antibiotic-resistant bacteria are the result of bacteria that specifically modify their own chromosomal DNA to neutralize the antibiotics
d. The antibiotic alters the bacterial genome of each bacterium, which results in an antibiotic-resistant population
How do you know your answer is the correct one?
Answer:
b. The genes for antibiotic resistance are located on a plasmid that can be passed to neighboring bacteria.
Explanation:
Conjugation refers to the process where one bacterium known as 'donor' transfers genetic material to another bacterium by direct contact. Conjugation enables bacteria to transfer genes that encode proteins conferring antibiotic resistance to another bacteria by transferring plasmids (i.e., small, extrachromosomal DNA molecules) containing these genes, which is known as horizontal transference. Plasmids that contain multiple antibiotic resistance genes confer Multidrug drug resistance (MDR) and they may severely limit the therapeutic efficacy of treatments against bacteria.
There are different kinds of antibiotics. The statement that best explains how the genes for antibiotic resistance can be transmitted between bacteria without the exchange of bacterial chromosomal DNA is that;
The genes for antibiotic resistance are located on a plasmid that can be passed to neighboring bacteria.Bacteria are known to be able to get antibiotic resistance genes from other bacteria in different ways. It can be gotten when they undergo a simple mating process referred to as "conjugation".
Bacteria are known to transport genetic material such as genes encoding resistance to antibiotics that are resident on plasmids and transposons. This can be transferred from one bacterium to another.

Explanation:
Huntington's disease, which causes degeneration of neurons, runs in Mark's family. Huntington's is a heritable, autosomal dominant genetic disease. In an autosomal dominant disease, only one abnormal allele is required to cause the disease in offspring. However, it is possible that not all offspring will receive the abnormal allele from an affected heterozygous parent. Family members that have the disease include Mark's maternal grandfather and Mark's maternal aunts. Mark's maternal grandmother does not have the disease. Because symptoms of Huntington's disease do not appear until later in life, genetic testing is necessary to determine whether a younger individual possesses the allele for the disease. These tests determined that Mark's mother does not carry the allele for Huntington's disease. Mark's paternal aunt suggested that Mark create a pedigree to track the disease in his family. Use the symbols provided to complete the pedigree. Each symbol may be used more than once.
Answer:
The correct answer is - maternal grandmother unaffected, maternal father affected, two maternal aunts affected, mother not affected and paternal side not affected so Mark is also not affected. (check the image)
Explanation:
As we know Mark's paternal grandparents do not have Huntington's disease. If the grandparents are normal the father and paternal aunt of Mark does not carry the disease allele therefore the symbols on the right represent Mark's paternal family.
We also know that the grandfather from the maternal side is affected and maternal aunts also have Huntington's disease, it is found out by the genetic testing that the mother is unaffected which means Mark will be unaffected as well as mother and father both are normal.

Jack And Betty are married, and they have two sons and one daughter. Jack's mother is deceased, but his father is still living. Betty's parents are both still alive. Jack's mother showed trait A, but his father does not. Jack and one of his sons show trait A, but the other son and daughter are free of the trait. No one on Betty's side of the family shows the trait. The trait is inherited as a recessive. Determine the genotype of each member of the extended family.

Proteoglycans are part of the extracellular matrix; they provide structure, viscosity and lubrication, and adhesiveness. They are composed of proteins conjugated to carbohydrate components called glycosaminoglycans. The glycosaminoglycan component makes up the majority of the mass of a proteoglycan. Which of these are possible components of glycosaminoglycans
Answer:
This question lacks options, options are: a. beta-D-fructofuranose b. amylose c. uronic acid d. N- acetylglucosamine. The correct answers are c and d.
Explanation:
Glycosaminoglycans are very long, unbranched polysaccharides, made up of repeating units of disaccharides. One of the disaccharides is always an amino sugar, which can be N- acetylglucosamine. The other is uronic acid (it can be iduronic acid or glucuronic acid and is often sulfated at position 2). The amino sugar is usually sulfated and the rest of the sugars have carboxyl groups, which give the structure a negative charge, which attracts a large amount of cations such as sodium. Glycosaminoglycans are often covalently bound to proteins to form proteoglycans. Hyaluronic acid is the only glycosaminoglycan that does not form protein bonds and does not have sulfate groups in its structure.
