A reverse transcriptase (RT) is an enzyme that copies RNA to DNA.

Reverse transcription is the process of creating complementary DNA (cDNA) from an RNA template using the enzyme reverse transcriptase (RT). Reverse transcriptases are utilised by mobile genetic components such as retrotransposons to multiply inside the host genome, by viruses like HIV and hepatitis B to reproduce their genomes, and by eukaryotic cells to lengthen the telomeres at the ends of their linear chromosomes.

'The cellular surface organizes the interior organelle organization of the cell'.

What do you mean by organelle?

Organelles are specialized compartments within a cell that perform specific functions. They are like the organs of a human body, performing a specific task within the cell. Examples of organelles include the nucleus, mitochondria, chloroplasts, endoplasmic reticulum, Golgi complex, lysosomes, and peroxisomes.

The cellular surface, or plasma membrane, acts as a barrier between the cytoplasm and the external environment. It also provides structure and organization to the interior of the cell by controlling the movement of molecules, ions, and other particles that enter and exit the cell. The membrane also contains various proteins and lipids that serve as receptors and are involved in signaling pathways that regulate cellular processes. By organizing the interior of the cell, the cellular surface helps to direct the activities of the organelles and ensure that they are located in the right places to function properly.

Heavy metals in the soil pose several problems, both for the environment and human health. These metals, including lead, arsenic, mercury, cadmium, and chromium, can accumulate in the soil through various sources such as industrial activities, mining, agriculture, and improper waste disposal.

The presence of heavy metals in the soil can lead to contamination of groundwater and surface water, affecting the surrounding ecosystems and biodiversity. In terms of human health, exposure to high levels of heavy metals can cause serious health problems, including respiratory issues, neurological disorders, organ damage, and even cancer.

Cleanup of soil contaminated with heavy metals is a challenging and complex task. Various remediation techniques are employed to mitigate the risks associated with heavy metal contamination.

These techniques include physical methods such as excavation and removal of contaminated soil, soil washing, and stabilization or immobilization of the metals. Chemical methods like soil flushing and soil vapor extraction can also be used.

Additionally, biological methods such as phytoremediation, which involves using plants to extract or neutralize heavy metals, and microbial remediation, where microorganisms are utilized to degrade or transform the contaminants, are employed.

The selection of an appropriate cleanup method depends on factors such as the type and concentration of heavy metals, the extent of contamination, the site conditions, and the intended land use after remediation.

It is important to consider the long-term effectiveness, feasibility, and cost-effectiveness of the chosen remediation approach. Proper management of contaminated soil and prevention of further heavy metal pollution are crucial to protect both the environment and human well-being.

Answer:

22mm²  

Explanation:

There are 6 sides of a "cell": 3 different types of sides with different dimensions that are multiplied twice because there is a front and back side with the same dimensions.

Front and back side = 2 × 5mm × 1mm

                                 = 10mm²

Left and right side = 2 × 1mm × 1mm

                              = 2mm²

Up and down side = 2 × 5mm × 1mm

                               = 10mm²

Total surface area = 10mm² + 2mm² + 10mm²

                              = 22mm²

The incidence of Down syndrome births increases with increasing age of the mother therefore the correct option is B.

Down syndrome is more  frequently the result of nondisjunction during oogenesis rather than during spermatogenesis. Studies have  set up that the  threat of having a child with Down pattern increases significantly with  adding   motherly age, with the loftiest  threat seen in  maters over 40 times old.

This suggests that the chromosomal abnormalities associated with Down pattern are more likely to  do during oogenesis, which occurs before birth and isn't affected by the mother 's age.

Exocytosis.

Explanation:

A cell can be defined as the structural, fundamental, biological and functional unit of life. Cells are found in all living organisms because they are the basic unit of life. A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells. Generally, cells have the ability to independently replicate themselves. In a cell, the "workers" that perform various functions or tasks for the survival of the living organism are referred to as organelles

Exocytosis can be defined as a process which typically involves a cell releasing a large amount of a material (bulk transport) outside of the cell, using vesicles.

This ultimately implies that, exocytosis is a process in which living organisms release or expel large amount of unwanted material through the use of vesicles. Vesicles are cell organelles that ensure materials are properly transported to the right and exact location.

Additionally, exocytosis is a process initiated by the Golgi apparatus because it prepares the material for export by chemically tagging them.

This pre-Cambrian period period is divided into three eons: the Hadean, Archean, and Proterozoic. The end of the pre-Cambrian period is marked by the appearance of complex, multicellular animals during the Cambrian explosion, which is considered to be one of the most significant events in the history of life on Earth. Before the Cambrian explosion, life on Earth was dominated by simple, single-celled organisms like bacteria and algae.

The vibrating object that creates the disturbance could be the vocal cords of a person, the vibrating string and sound board of a guitar or violin, the vibrating tines of a tuning fork, or the vibrating diaphragm of a radio speaker.

Regardless of what vibrating object is creating the sound wave, the particles of the medium through which the sound moves is vibrating in a back and forth motion at a given frequency.

The frequency of a wave refers to how often the particles of the medium vibrate when a wave passes through the medium. The frequency of a wave is measured as the number of complete back-and-forth vibrations of a particle of the medium per unit of time.

One possible explanation relating a variety of species within an ecosystem to the overall balance of the ecosystem The variety of species helps support more abiotic factors.

Correct option is A.

This is due to the way that each species meets a particular niche in the ecosystem, which leads to competition for available resources. This level of competition prevents any one organism or set of organisms from monopolizing resources and alters the balance of the ecosystem.

Furthermore, the variety of life helps to increase the number of abiotic factors such as water, sunlight, and air that are needed for life to thrive. Ultimately, the diversity of species within a rainforest ecosystem helps to keep the delicate balance of the ecosystem in check.

The opening of sodium (Na)-selective channels will lead to depolarization of the cell membrane because the sodium equilibrium potential is typically more negative than the resting potential.

This means that the membrane potential of the cell will become more positive when the Na-selective channels open, which is the opposite of what would happen if the equilibrium potential were more positive than the resting potential.

When the Na-selective channels open, the concentration of Na⁺ ions inside the cell increases due to a net movement of Na⁺ ions out of the cell. This influx of Na⁺ ions causes a decrease in the negative charge inside the cell, resulting in an increase in the membrane potential of the cell.
