Which agent of erosion is mainly responsible for the formation of the barrier islands along the southern coast of Long Island, New York?
Mass movement
Explanation:
Answer:
D) Ocean waves
Explanation:
Barrier islands are types of landforms that are created or formed when ocean currents which act as an agent of erosion, deposit sediments such as sands, rock particles opposite or parallel to the mainland coast.
Barrier Islands tend to be flat in shape and have dune present in them.
They help to protect the coastal areas from storms that can cause flooding and erosion.
Barrier Islands can be found along the southern coast of Long Island, New York.

The sarcomere shortens when the myosin heads of the thick filaments
Answer:
The sacromere shorten when
When the myosin heads of the thick filaments in a cocked direction, form cross bridges with actin molecule in the thin filament.
Explanation:
Sacromere is the functional unit of straited muscle and muscle contractions. It initiate involuntary movement.
The sacromere shorten when
When the myosin heads of the thick filaments in a cocked direction, form cross bridges with actin molecule in the thin filament. It cause the sacromere in the muscle fibre to shorten and skeletal muscles to contract
Answer:
The correct answer is: form cross bridges with the actin molecules of the thin filaments.
Explanation:
The sarcomere makes up the unit of the striated muscle tissue, and is the structure responsible for the contractility of this tissue. Sarcomeres are composed of two types of filaments: thick filaments formed by myosin molecules, and thin filaments that are formed by actin molecules. In order to contraction to happen, the thin and the thick filaments move between one another in a coordinated manner to shorten the sarcomere and produce muscle contraction.
For muscle contraction to happen, myosin heads bind to the actin molecule by forming a cross-bridge with it -this happens when the actin-binding site that is commonly hidden by the proteins troponin and tropomyosin, is uncovered thanks to the arrival of calcium ions-. This binding allows the sliding mechanism that will end up shortening the sarcomere.

The endocrine system stops quickly when stimulus stops.
Answer:
The nervous system releases neurotransmitters at synapses at specific target cells & The endocrine system reacts more slowly to stimuli, often taking seconds to days.
Explanation:
The nervous system is very specific with where the neurotransmitters go so they will affect target cells. The endocrine system is slower than the nervous system because the hormones travel through the blood so it takes much longer to reach the designated area.
Neurotransmitters are released by the nervous system at synapses with certain target cells.
How nervous system works?The endocrine system responds to stimuli more slowly, frequently taking minutes to days.
The fact that the nervous system utilizes electrical impulses to convey signals through neurons while the endocrine system uses hormones to deliver instructions to the target cells through circulation is one of the most important distinctions between the two systems.
Neurons interact with one another throughout the nervous system through electrical and chemical signals.
Therefore nervous system utilizes electrical impulses to convey signals through neurotransmitters.

: increasing capacity for bodily or mental labor especially by eliminating fatigue symptoms an ergogenic drug.
Final answer:
Ergogenic aids are substances that improve energy production or recovery, but they carry serious health risks and ethical concerns. Anabolic steroids and hormones like erythropoietin and human growth hormone are banned by major athletic organizations due to the dangers they pose and the unfair advantage they provide. Their use can lead to irreversible side effects, including heart disease, infertility, and aggressive behavior.
Explanation:
Ergogenic aids are substances or devices that enhance energy production, use or recovery and provide athletes with a competitive advantage. Among the most recognized ergogenic aids are anabolic steroids, which are synthetic variations of the male sex hormone testosterone. While anabolic steroids can build muscle mass and improve athletic performance, their use is associated with severe and sometimes irreversible health risks.
Other common performance-enhancing hormones include erythropoietin, which boosts red blood cell production, and human growth hormone, which can aid in muscle building. The use of these substances raises significant ethical concerns as they offer an unfair advantage over competitors and are considered a form of cheating. Furthermore, ergogenic aids can cause serious, nonreversible side effects that can be fatal, such as increasing the risk of heart attacks, infertility, and aggressive behavior, commonly referred to as "roid-rage".
All major athletic organizations, including the International Olympic Committee, National Collegiate Athletic Association, Major League Baseball, and National Football League, have banned the use of performance-enhancing drugs due to the health risks and the unfair competitive advantage they provide.
Do you think humans exhibit traits of r- or K-selection? Explain your reasoning.
Answer:
Humans definitely show characteristics of K-selection. Humans have a longer life span than many organisms. They also have few offspring. On average, humans take 12 to 15 years to reach sexual maturity. Humans also care for their young until they’re mature enough to live on their own
Explanation:
Edmentum's sample answer
K and r selection are the part of the Darwinian fitness that depicts the lifespan and the number of offspring. Humans exhibit traits of K-selection as they have a longer lifespan.
What is r- or K-selection?r- or K-selection is the factor of the fitness and survival possessed by the organisms. r-selected species are small in size and are used generally for reproduction. Though the species is smaller in size with a short lifespan that produces a large number of offspring.
On the other hand, K-selected organisms are large and have a longer life span. K refers to the carrying capacity of the species. The organisms tend to give birth to fewer offsprings that undergo maturity and many phases that takes years.
Therefore, humans possess K selection.

Which of the following would be selective against the tubercle bacillus? Group of answer choices streptogramin – inhibits protein synthesis vancomycin – inhibits peptidoglycan synthesis ethambutol – inhibits mycolic acid synthesis streptomycin – inhibits protein synthesis bacitracin – inhibits peptidoglycan synthesis
Answer:
C) ethambutol inhibits mycolic acid synthesis
Explanation:
Ethambutol is an antimycobacterial agent which is used in the treatment of tuberculosis. However, Ethambutol is to be given in combination with some other drug.
It inhibits the tubercle bacillus and synthesis of spermidine in mycobacteria by inhibiting the transfer of mycolic acids into the cell wall which further stimulates the synthesis of trehalose dimycolates This is bactericidal and may produce lethal effect if it penetrates into the human cell.
Option C is the right choice of answer
Ethambutol is the antibiotic that selectively targets and inhibits mycolic acid synthesis, making it effective against the tubercle bacillus.
Explanation:The tubercle bacillus, which causes tuberculosis, has a unique cell wall that includes a waxy substance called mycolic acid. This substance is essential for the survival of the bacteria, and its synthesis can be targeted by certain antibiotics for selective toxicity.
Of the antibiotics listed, ethambutol is the one that inhibits mycolic acid synthesis, making it selectively active against the tubercle bacillus. While other antibiotics listed, such as streptomycin and vancomycin, are effective against various bacteria by inhibiting protein synthesis or peptidoglycan synthesis, they do not offer the same targeted action against mycolic acid synthesis as ethambutol.
In what sense is influenza a zoonotic disease? A. It has animal reservoirs, especially birds and swine. B. It is transmitted by "stealth" arthropods. C. It is transmitted frequently by contact with wool. D. The main reservoir is wild carnivores. E. None of the above.
Answer:
A. It has animal reservoirs especially birds and swine
Explanation:
A zoonotic disease is something that normally exists in animals as in animal resevoirs like birds and swine, but can be transmitted to humans. When this happens our body does not have the proper antibodies prepared to combat the infection as it is foreign to us.
Influenza is a zoonotic disease because it can be transmitted from animal reservoirs, like birds and swine, to humans. The Influenza A virus is especially known for being transmitted from these animals to humans, and such transmissions can lead to widespread human outbreaks.
Explanation:In what sense is influenza a zoonotic disease? The answer is A. It has animal reservoirs, especially birds and swine. Influenza is considered a zoonotic disease because it is caused by pathogens that can be passed from animals, particularly birds and swine, to humans. Influenza A virus can be transmitted from these animal reservoirs to humans through direct contact or exposure to contaminated environments. The flu virus is highly contagious among humans through respiratory secretions and can cause significant outbreaks and pandemics.
Furthermore, a pathogen may have more than one living reservoir. These animal carriers may also be asymptomatic, harboring the virus without showing any signs of the disease themselves. The zoonotic nature of influenza emphasizes the importance of monitoring animal populations for signs of the virus to prevent transmission to humans.

The diploid number of a roundworm species is 4. Assuming there is no crossover, and random segregation of homologs during meiosis, how many different possible combinations of chromosomes might there be in the offspring?
There are 4 possible combinations of chromosomes in the offspring of a roundworm species with a diploid number of 4, assuming no crossover events occur.
To determine the number of possible combinations of chromosomes in the offspring, we need to consider the random segregation of homologous chromosomes during meiosis.
For a diploid organism with 'n' chromosome pairs, the number of possible combinations is given by 2n. In this case, the diploid number of roundworm is 4, which means there are 2 pairs of chromosomes (n = 2).Using the formula:[tex]2^2[/tex] = 4
