why do you think meteors leave a trail of light as they move through the sky?

No, snails have no gender as they're hermaphrodites. Garden snails produce sperms like males and carry eggs like females at the same time.

Snails have both female and male reproductive cells as they are hermaphrodite. They don't actually need to mate with another snail to reproduce and self fertilization is possible. After mating they lay about 80 white eggs in a damp and underground nest.

Snails called slipper limpets begin life as males, and then become female as they grow. A new study has shown that when two males are kept together and in contact with one another, the larger one changes to female sooner, and the smaller one later.

Soils high in shrink/swell clays, such as montmorillonite, characterize Vertisols soil order.

A vertisol, also known as vertosol, is a soil type with a high content of expansive clay minerals, many of which are montmorillonite, which form deep cracks in drier seasons or years. Vertisols are clay-rich soils that experience extensive vertical cracking during the dry seasons. They are best suited for use as pastureland and the cultivation of plants that thrive in standing surface water, such as rice, and typically form under grassland vegetation in basin or rolling hill landscapes.

Heavy clay soils with a high proportion of swelling clays are being churned by vertisols. When these soils dry out, which happens most years, they form deep wide cracks from the surface downward. The name Vertisols (from L. vertere, to turn) refers to the constant internal turnover of soil material.

While providing habitat for 25% of all marine species and receiving close to 500 million visitors annually, coral reefs are also the most endangered marine ecosystem on earth.

You can help safeguard coral reefs and the fish, animals, and plants that rely on them by taking a few straightforward, practical measures.

1. When diving at coral reefs, exercise caution.

The reef should not be touched or anchored by vessels. Corals can die if they come into contact with the reef or if they are anchored there.

2. Use a sunscreen that respects the reefs.

Coral reefs have been found to be harmful to a number of common sunscreen chemicals, including oxybenzone and octinoxate. Coral bleaching is not a result of sunscreens with non-nano zinc oxide as one of their active constituents.

When using an AED, a person must remember to check pulse before resuming compressions after a shock. Thus, the correct option is A.

An AED is an automated external defibrillator (AED). It is a medical device which is designed to analyze the heart rhythm and deliver an electric shock to the victims of ventricular fibrillation to restore the heart rhythm to normal levels. Ventricular fibrillation is the uncoordinated irregular heart rhythm which is most often responsible for sudden cardiac arrest.

AEDs are used to revive patients from sudden cardiac arrest. This condition usually occurs when a disruption in the heart's electrical activity causes a dangerously fast heartbeat which is known as ventricular tachycardia or a fast and irregular heartbeat that is ventricular fibrillation.

Protein is the sequence of amino acids that could be translated from the sequence of mRNA.

Proteins are large macro- and biomolecules made up of one or more long chains of amino acid residues. Proteins play a variety of roles in living things, including catalysing metabolic reactions, reproducing DNA, responding to stimuli, providing cells and organisms structure, and transporting chemicals.

The order of a protein's amino acids, which is dictated by the nucleotide sequence of its genes and normally enables a protein to fold into a certain 3D structure that regulates its function, is the main way that proteins differ from one another.

Various methods, including ultracentrifugation, precipitation, electrophoresis, and chromatography, can be used to separate proteins from other biological components. The development of genetic engineering has made several purification procedures possible. Immunohistochemistry, site-directed mutagenesis, X-ray crystallography, nuclear magnetic resonance, and mass spectrometry are techniques that are frequently used to research protein structure and function.

The density of mercury is greater and the mercury neither wets nor sticks to the glass tube therefore, it gives the correct reading. hence, mercury is used in barometer.

The barometer works by balancing the weight of mercury in the glass tube against the atmospheric pressure. if weight of mercury is less than the atmospheric pressure, the mercury level in the glass tube rises (high pressure). If it's more than atmospheric pressure, the mercury level falls (low pressure). Although, other liquids can be used in barometer, mercury is the common one. The density of mercury allows the vertical column of the barometer to be of manageable size. Using mercury in barometer is advantageous as its density is high it has low vapour pressure; its rate of evaporation is not very high. Mercury barometer is precise and offers a simple method of measuring the atmospheric pressure. Mercury is inexpensive and does not require any expensive equipment to be made.

Any "signs" of past life activity, like footprints or burrows, are called Trace fossils.

A trace fossil, also known as an ichnofossil, is a fossil record of biological activity that does not include the plant or animal's preserved remnants.

Body fossils, on the other hand, are the fossilized remnants of sections of creatures' bodies that have been transformed by subsequent chemical activity or mineralization. Ichnology is the study of such trace fossils and is the work of ichnologists.

Trace fossils can be organism-made imprints on or in the substrate. Burrows, borings (bioerosion), urolites (erosion induced by liquid waste outflow), footprints and feeding imprints, and root cavities are all examples of trace fossils.

In its widest definition, the word also refers to the remnants of other organic material generated by an organism, such as coprolites (fossilized droppings) or chemical markers (sedimentological structures produced by biological means.

Marine food webs would be altered, and many economically important species would vanish.

2) No More Tourists -Coral reefs also sustain smaller economies through tourism and attract tourists to over 100 countries. Without reefs to visit, there will be a reduction in tourist numbers, which will have a knock-on effect on local businesses that depend on year-round tourists.
