During muscle contraction, all of the following occur EXCEPT
A. Myosin heads bind to actin
B. ATP is hydrolyzed
C. Calcium concentrations in the sarcoplasm decrease
D.Calcium binds to troponin
E. Calcium concentration in the sarcoplasm increase
Answers
During muscle contraction, all of the following occur EXCEPT: C. Calcium concentrations in the sarcoplasm decrease.
The process of muscle contraction is initiated by an action potential that travels down a motor neuron and triggers the release of calcium ions from the sarcoplasmic reticulum (a specialized membrane system) into the sarcoplasm (the cytoplasm of the muscle fiber). The calcium ions then bind to troponin, which causes tropomyosin to move and expose binding sites on the actin filaments.
Myosin heads then bind to actin, forming cross-bridges. ATP is hydrolyzed by the myosin heads to provide energy for the cross-bridge cycle, which results in the sliding of actin filaments over myosin filaments and shortening of the muscle fiber. Calcium ions are actively transported back into the sarcoplasmic reticulum, causing the calcium concentration in the sarcoplasm to decrease, and allowing the actin and myosin filaments to dissociate.
Therefore, the correct answer is C. Calcium concentrations in the sarcoplasm decrease.

a. sexual reproduction.
b. binary fission.
c. parthenogenesis.
d. budding.
The correct option is C.
Parthenogenesis.
Explanation:
lizards undergo a process in which their unfertilized eggs can develop into new individuals and the process is called parthenogenesis because parthenogenesis is a reproductive strategy that involves the reproduction of new organisms without undergoing fertilization or the production of new organisms from unfertilized eggs and these can be as a result of the lizard not able to undergo sexual reproduction which can be as a result of environmental factors. This process does not involve sexual reproduction.
Mutation may occur in gametes or in body cells. In which cell type is a mutation likely to be source of genetic variation for ?
Answers
Answer:
Una mutación es el cambio al azar en la secuencia de nucleótidos o en la organización del ADN (genotipo) de un ser vivo,1 que produce una variación en las características de este y que no necesariamente se transmite a la descendencia. Se presenta de manera espontánea y súbita o por la acción de mutágenos. Este cambio estará presente en una pequeña proporción de la población (variante) o del organismo (mutación). La unidad genética capaz de mutar es el gen, la unidad de información hereditaria que forma parte del ADN.2
En los seres pluricelulares, las mutaciones solo pueden ser heredadas cuando afectan a las células reproductivas.3 Una consecuencia de las mutaciones puede ser, por ejemplo, una enfermedad genética. Sin embargo, aunque a corto plazo pueden parecer perjudiciales, las mutaciones son esenciales para nuestra existencia a largo plazo. Sin mutación no habría cambio, y sin cambio la vida no podría evolucionar.
Explanation:
when high levels of plasma calcium occur, the nurse is aware that the following hormone will be secreted:
Answers
When high levels of plasma calcium occur, the nurse would be aware that the hormone calcitonin is typically secreted.
Calcitonin is a hormone produced by the thyroid gland in response to elevated levels of calcium in the blood. Its primary function is to regulate calcium homeostasis by decreasing the concentration of calcium in the bloodstream. Calcitonin acts on the bones, kidneys, and intestines to reduce calcium levels through several mechanisms:Inhibition of bone resorption: Calcitonin inhibits the activity of osteoclasts, cells responsible for breaking down bone tissue. By suppressing osteoclast activity, calcitonin helps to prevent the release of calcium from bones into the bloodstream.Increased calcium excretion: Calcitonin promotes the excretion of calcium by the kidneys, reducing reabsorption and enhancing its elimination through urine.
By exerting these effects, calcitonin helps to regulate and lower plasma calcium levels when they are elevated. It works in opposition to another hormone called parathyroid hormone (PTH), which increases plasma calcium levels when they are low.

Answer: c humans would find more efficient ways of growing crops
Explanation:
Malthus fail to take into consideration that humans would find more efficient ways of growing crops. The correct option is B.
What is population?A population is the total number of individuals who reside in the same location.
The population of a city is the multitude of people who live there. These people are referred to as residents or tenants. The population includes all people who live in that specific area.
The population represents the total number of people living in a specific area at a given time.
The population is an important factor in balancing the environment; the population should be in rebalancing with the means and resources.
An imbalance between births and deaths is the primary (and perhaps most obvious) cause of population growth.
Malthus fails to consider that humans would develop more efficient crop-growing methods.

why must primase be used before dna polymerase when replicating dna?
Answers
DNA polymerase will then use the RNA primer's 3'-OH group to continue adding nucleotides and extend the DNA strand. DNA polymerase needs a primase to start replicating DNA.
Primase, on the other hand, is an enzyme that synthesizes RNA primers. Primase is needed before DNA polymerase to create a starting point for DNA polymerase to begin adding nucleotides.
Since DNA polymerase needs a free 3' OH group to initiate the attachment of the next nucleotide, primase adds RNA primers to act as a starting point for DNA polymerase to attach and add nucleotides. Primers are necessary for the initiation of DNA synthesis since DNA polymerase cannot initiate chain synthesis.
Only a pre-existing nucleic acid chain is used as a template, and nucleotides are added to the 3′ end of the growing chain. Primase is required for DNA replication since it adds RNA primers that bind to the complementary DNA strand's template.

why can undescended testes cause infertility?the testes are exposed to a higher internal body temperature, slowing sperm development.the testes become entangled in the seminiferous tubules, which then degenerate.the testes undergo apoptosis, and can no longer produce sperm.the testes secrete very little testosterone.
Answers
Undescended testes, also known as cryptorchidism, can cause infertility due to several reasons.
Firstly, when the testes fail to descend into the scrotum, they remain in the abdominal cavity, which exposes them to a higher internal body temperature. This temperature is not suitable for the normal development of sperm, which requires a cooler environment. Therefore, the testes may not be able to produce enough healthy sperm for fertilization, leading to infertility.
Secondly, undescended testes can become entangled in the seminiferous tubules, which are responsible for the production of sperm. This can cause the tubules to degenerate, leading to a reduction in the number of sperm produced. As a result, the chances of successful fertilization are reduced, leading to infertility.
Thirdly, the testes may undergo apoptosis, which is a process of programmed cell death. This occurs when the testes are unable to function correctly due to their location, leading to a reduction in the production of sperm. Eventually, the testes may not be able to produce sperm at all, leading to infertility.
Lastly, undescended testes may secrete very little testosterone, which is a hormone that is essential for the development of male reproductive organs and the production of sperm. A lack of testosterone can lead to infertility as it affects the overall reproductive function.
Undescended testes can cause infertility due to the exposure to a higher internal body temperature, entanglement in the seminiferous tubules, apoptosis, and a lack of testosterone. These factors can affect the production and quality of sperm, leading to difficulties in fertilization and conception.
