Answer:

Insulin enables blood glucose to enter cells, where they use it to produce energy. Together, insulin and glucagon help maintain homeostasis, where conditions inside the body hold steady. When a person's blood sugar is too high, their pancreas secretes more insulin.

Insulin allows the cells in the muscles, fat and liver to absorb glucose that is in the blood. The glucose serves as energy to these cells, or it can be converted into fat when needed. Insulin also affects other metabolic processes, such as the breakdown of fat or protein.

Answer: flows INTO the synaptic knob.

When a nerve impulse reaches the end of an axon of a neuromuscular junction, calcium flows into the synaptic knob.

In a neuromuscular junction, there are three parts. They are the presynaptic terminal or synaptic knob, the synaptic cleft and the postsynaptic terminal. The calcium ions will work in the synaptic knob when the nerve impulse arrives.

Once that the nerve impulse reaches the end of the axon, it will affect the presynaptic terminal. In there, it causes the opening of voltage-gated calcium channels. As a result:

In conclusion, the nerve impulse causes the opening of voltage-gated calcium channels, and calcium flows into the synaptic knob.

DNA-DNA hybridisation is used to check the similarity in organisms.

Evolution is defined as change in the characteristics that acquired heritableyand of population exposed to generations which are successive. There are several stages of evolution through which an organism pass to achieve the evolution and these are mutation, after that genetic recombination, reproduction isolation, and natural selection.

The neck of the giraffe is the best example of evolution as the time change the length of the neck of the giraffe becomes long because due to height of tree they strech their neck and due to practice over a long time the evolution takes place and their neck become long in length. Evolution is a time taking or long process.

In thale cress plants, water-deficit stress leads to the transcriptional repression of the gtl1 gene.

This repression promotes the biosynthesis of anthocyanin and polyamines, which are compounds associated with enhanced drought tolerance.

These biochemical changes help the plants adapt and cope with water scarcity.

The transcriptional repression of gtl1 by water-deficit stress promotes anthocyanin and polyamine biosynthesis to enhance drought tolerance in Thale cress, according to recent research.

Anthocyanin is a plant pigment that is responsible for flower and fruit coloration.

It is a water-soluble pigment that is involved in various physiological processes in plants, including cell protection from environmental stress.

Polyamines, on the other hand, are organic compounds that are widely distributed in living organisms and are involved in cell growth, differentiation, and division, as well as stress tolerance.

In response to water-deficit stress, plants undergo transcriptional changes to adapt to the harsh conditions. Researchers have discovered that the gtl1 gene in Thale cress (Arabidopsis thaliana) is downregulated by water-deficit stress, leading to increased biosynthesis of anthocyanin and polyamine.

The research discovered that anthocyanin accumulation in Thale cress helps to protect cells from oxidative damage caused by drought stress.

Polyamines, on the other hand, were discovered to play a role in drought tolerance by increasing water retention and stress signaling pathways.

The findings suggest that transcriptional repression of gtl1 is a key mechanism by which Thale cress adapts to water-deficit stress by promoting anthocyanin and polyamine biosynthesis to enhance drought tolerance.

These results have the potential to be used in crop improvement by developing drought-tolerant crops.

d. flea. Endemic typhus, also known as murine typhus, is a bacterial infection caused by the bacterium Rickettsia typhi.

It is transmitted to humans through the bites of infected fleas that live on rats, opossums, and other small mammals. The bacteria are present in the feces of infected fleas and can enter the human body through a break in the skin or through inhalation of infected flea feces.

Endemic typhus is a type of typhus that is characterized by fever, headache, muscle aches, and a rash. The symptoms typically appear 1-2 weeks after exposure to the infected flea. The disease is not usually fatal, but it can be serious for people with weakened immune systems.

Endemic typhus is found throughout the world, but it is most common in areas with poor sanitation and where there are high populations of rodents and their fleas. Risk factors for infection include exposure to rodents, contact with flea-infested areas, and poor hygiene practices.

The diagnosis of endemic typhus is made based on symptoms and confirmed through blood tests that detect the presence of antibodies against the bacteria. Treatment typically involves antibiotics, such as doxycycline or azithromycin. Prevention of endemic typhus involves controlling rodent populations, practicing good hygiene, and avoiding contact with flea-infested areas.

The estimated required sterilization time to reduce the contamination to one in 1000 fermentation is approximately 3.125 x 10⁶ minutes.

To estimate the required sterilization time to reduce the contamination to one in 1000 fermentations, we need to consider the specific death rate of the spores at 121°C. The specific death rate is given as 3.2 min⁽⁻¹⁾.
First, we need to determine the time required for a single spore to be completely killed. We can do this by taking the reciprocal of the specific death rate: 1/3.2 min⁽⁻¹⁾ = 0.3125 minutes (or approximately 18.75 seconds).

Next, we need to calculate the number of sterilization cycles required to reduce the contamination to one in 1000. Since the contamination is initially 10¹⁰ spores, we divide this by 1000 to get 10^7 spores.
Now, we multiply the time required for a single spore to be killed by the number of sterilization cycles needed: 0.3125 minutes/cycle x 10⁷ cycles = 3.125 x 10⁶ minutes.
Therefore, the estimated required sterilization is approximately 3.125 x 10⁶ minutes.

Explanation:

The Precambrian era is said to have taken place during the early years of our planet. During this time, the levels of oxygen in the atmosphere were much greater than they are today.

This level of increased oxygen in the atmosphere is a direct result of the biological processes and the sheer number of certain organisms present in Precambrian-era oceans.

Though the options stated all depict ways in which oxygen entered the atmosphere during the Precambrian era, the increase of oxygen levels is credited to the cyanobacteria.

The cyanobacteria were among the few living organisms present on the Earth during this time. They are small algae that use photosynthesis to sustain themselves.

Photosynthesis is known to produce and release oxygen as a waste product. This and the vast number of cyanobacteria present at the time account for the increase in oxygen levels during this era.
