Answers
In the resting state, due to the concentrations of sodium and potassium ions on either side of the plasma membrane, the neuron is said to be polarized.
A neuron's sodium and potassium ion concentrations on either side of the plasma membrane differ when the neuron is at rest. While K⁺ concentration is higher inside the neuron, Na⁺ concentration is higher outside the neuron. The resting membrane potential which is caused by this concentration difference, exists across the membrane.
An average neuron's resting membrane potential measures around -70 millivolts and is regarded as polarized. This indicates that the internal charge of the neuron is slightly negative compared to the external charge. The ion channels and pumps found in the membrane of the neuron help to actively transport ions, maintaining this polarization.
It prepares the neuron for producing and sending electrical signals in response to appropriate stimulation.

Dozens of earthquakes hit Hawaii as the world's largest volcano erupts
On November 27, Mauna Loa erupted for the first time in nearly 40 years. Located in Hawaii, Mauna Loa is the world's largest active volcano. Volcanoes are openings or vents where lava, small rocks, and steam erupt onto the Earth's surface. Melted rock that comes up from inside the Earth and out of a volcano is lava. The Mauna Loa eruption occurred at the Moku'āweoweo summit caldera. This is a large sunken basin at the summit — or highest point — of the volcano.
Following the eruption, dozens of earthquakes swarmed the region — one of them a magnitude 4.2 quake. Magnitude is a number that characterizes the relative size of an earthquake from 1 to 9.
Remain Vigilant
Officials issued an ashfall advisory for Hawaii's Big Island and asked residents to remain vigilant. So far the eruption's lava flows pose no risk to people living downhill from the eruption, according to Hawaii's Tourism Agency.
Map showing lava flow of Mauna Loa from the years 1843 to 1984.
Image 1. The volcano's last eruption was in 1984, when it sent a lava flow close to the city of Hilo.
"At this time, lava flows are contained within the summit area and are not threatening downslope communities," said officials from the U.S. Geological Survey (USGS). The USGS is a government agency that collects information to help monitor natural hazards such as earthquakes. They warned, however, that the location and advance of lava flows can change rapidly.
The USGS's Hawaiian Volcano Observatory noted that it is set to perform flights to assess the eruption. They warned that "winds may carry volcanic gas and possibly fine ash and Pele's hair downwind." Pele's hair are thin strands of volcanic glass formed from cooling lava. The glass is sometimes carried into the air by strong winds and is sharp enough to tear skin and eyes.
Monitoring The Volcano
Mauna Loa takes up more than half of Hawaii's Big Island. It rises 13,679 feet (4,169 meters) above the Pacific Ocean, according to the USGS. The volcano is fairly active, having erupted 33 times since its first well-documented eruption in 1843. Its last eruption was in 1984 when it sent a lava flow close to the city of Hilo. After that, Mauna Loa entered its longest dormant period in recorded history. Periods of time when the volcano is not erupting, but could in the future, are volcanic dormant periods.

4. Describe Lamarckian and Darwinian ideas about Evolution, and highlight the key differences between them. 5 marks
Answers
Lamarckian and Darwinian ideas about evolution differ in their explanations for how species change over time. Lamarckism proposes that acquired characteristics can be inherited, while Darwinism emphasizes natural selection and variation as driving forces of evolution.
Lamarckian and Darwinian ideas about evolution have fundamental differences in their explanations:
Lamarckism, proposed by Jean-Baptiste Lamarck, suggests that acquired characteristics during an organism's lifetime can be passed on to the next generation. Lamarck argued that organisms change in response to their environment and these changes are then inherited. For example, if a giraffe stretched its neck to reach higher leaves, its offspring would inherit a longer neck.
On the other hand, Darwinism, formulated by Charles Darwin, centers around natural selection and variation. Darwin proposed that organisms with favorable traits are more likely to survive and reproduce, passing those advantageous traits to subsequent generations. This process, known as "survival of the fittest," leads to the gradual accumulation of beneficial traits in a population over time.
The key differences between Lamarckism and Darwinism are:
1. Inheritance of acquired characteristics: Lamarckism suggests it is possible, while Darwinism rejects this idea.
2. Mechanism of change: Lamarckism proposes that organisms change in response to the environment, while Darwinism emphasizes natural selection acting on variations already present in a population.
3. Timescale: Lamarckism implies rapid and continuous change, while Darwinism allows for gradual and cumulative changes over long periods of time.
In summary, Lamarckian evolution focuses on the inheritance of acquired characteristics, while Darwinian evolution emphasizes natural selection and the accumulation of beneficial variations over time. Darwin's theory of evolution by natural selection is widely accepted and forms the basis of modern evolutionary biology.

b.The gametes are the haploid phase of the animals life cycle.
c. Meiosis is not a necessary component of the animal life cycle.
d. The products of the haploid phase of the life cycle are larger than those of the diploid phase.
Answers
Among the given options, statement b. "The gametes are the haploid phase of the animal's life cycle" is true.
In the life cycle of animals, the gametes (sperm and egg cells) are the reproductive cells involved in sexual reproduction. Gametes are produced through a specialized cell division called meiosis, which reduces the chromosome number by half, resulting in haploid cells.
During sexual reproduction, haploid gametes from two parents combine to form a diploid zygote, which then develops into an organism. The zygote undergoes mitotic cell divisions, growing into a multicellular organism, and the diploid phase of the life cycle begins.

What factors may affect the success of the decellularization process?
Answers
Answer:
Decellularization is the process used in biomedical engineering to isolate the extracellular matrix (ECM) of a tissue from its inhabiting cells, leaving an ECM scaffold of the original tissue, which can be used in artificial organ and tissue regeneration. Organ and tissue transplantation treat a variety of medical problems, ranging from end organ failure to cosmetic surgery. One of the greatest limitations to organ transplantation derives from organ rejection caused by antibodies of the transplant recipient reacting to donor antigens on cell surfaces within the donor organ. Because of unfavorable immune responses, transplant patients suffer a lifetime taking immunosuppressing medication.

Answers
Answer:
B) is responsible for the release of the tRNA.
Explanation:
A transfer ribonucleic acid (tRNA) is an RNA molecule that connects a particular triplet of nucleotides or 'codon' of a messenger RNA (mRNA) to a particular amino acid during protein synthesis (translation) in the ribosomes. In a cell, tRNAs can be found in three different forms: aminoacyl-tRNAs, peptidyl-tRNAs, or deacylated tRNAs. Moreover, during translation, the tRNA binds to the ribosome at three different sites. The E-site (E for exit) refers to the final binding site for deacylated tRNAs in the ribosomes (i.e., before their dissociation from the ribosomes) during protein synthesis. The first binding site for tRNA in the ribosome is the A-site (A for aminoacyl), while the second binding site is called P-site (P for peptidyl). These three sites are oriented in inverse sense (5' to 3' E-P-A) with respect to the mRNA.

aristo biology conneectign concepts investigation of the effect of temperature on enzyme activity
Answers
The investigation of the effect of temperature on enzyme activity involves studying how changes in temperature can impact the rate of enzyme-catalyzed reactions.
Enzymes are biological catalysts that speed up chemical reactions within living organisms. They are highly sensitive to changes in temperature, as their activity is influenced by the kinetic energy of the molecules involved. In general, as temperature increases, the rate of enzyme activity also increases, up to a certain point. This is because higher temperatures provide more energy to the reacting molecules, leading to more frequent collisions and increased reaction rates
However, there is an optimal temperature for each enzyme at which it exhibits maximum activity. This optimal temperature is often specific to the enzyme and the organism it is derived from. Beyond this temperature, the enzyme's structure becomes denatured, leading to a loss in its catalytic ability. Denaturation occurs as the heat disrupts the enzyme's delicate three-dimensional structure, causing it to lose its active site shape and rendering it nonfunctional.
On the other hand, at temperatures below the optimal range, the enzyme activity decreases due to reduced molecular motion and collision frequency. This decrease occurs because the molecules have lower kinetic energy and move more slowly, resulting in fewer successful collisions and decreased reaction rates.
In summary, the investigation of the effect of temperature on enzyme activity reveals the complex relationship between temperature and enzyme function. While moderate temperature increases can enhance enzyme activity, extreme temperatures can have detrimental effects, ultimately leading to the loss of enzyme function. Understanding these temperature-dependent effects is crucial for various fields, including biotechnology, medicine, and agriculture.

Temperature affects enzyme activity by altering the enzyme's structure, which in turn affects its ability to catalyze reactions efficiently.
Enzymes are biological molecules that act as catalysts, facilitating chemical reactions within living organisms. The activity of enzymes is highly dependent on temperature. In general, as temperature increases, the rate of enzyme-catalyzed reactions also increases, up to a certain point called the optimum temperature. Beyond this optimum temperature, the enzyme's activity begins to decline.
The effect of temperature on enzyme activity can be explained by the enzyme's structure. Enzymes are three-dimensional proteins, and their shape is crucial for their function. High temperatures cause the enzyme to vibrate more, which disrupts the bonds that maintain its specific shape. As a result, the enzyme's active site, where the substrate binds, may undergo conformational changes or denaturation. This alteration in the enzyme's structure affects its ability to interact with the substrate, leading to a decrease in enzymatic activity.
On the other hand, low temperatures can also impact enzyme activity. At low temperatures, the enzyme and substrate molecules move slower, reducing the likelihood of successful collisions. This lowers the rate of enzyme-substrate complex formation and slows down the overall reaction rate.
Understanding the effect of temperature on enzyme activity is crucial in various fields of biology, such as biochemistry, molecular biology, and biotechnology. It allows scientists to optimize enzyme reactions by adjusting temperature conditions. Additionally, studying the temperature sensitivity of enzymes helps researchers investigate the adaptation mechanisms of organisms to different environments.

In many populations, the ability to digest lactose declines after childhood, as the production of lactase, the enzyme that breaks down lactose, decreases.
However, some individuals carry a genetic variant that allows them to maintain lactase production into adulthood, allowing them to digest lactose-containing foods.
