Answer:

The main properties of water are its polarity, cohesion, adhesion, surface tension, high specific heat, and evaporative cooling. A water molecule is slightly charged on both ends. This is because oxygen is more electronegative than hydrogen. ... The stream of water bends due to the polarity of water molecules.

Answer:

The total travelled distance is [tex]51065 \mathrm{~m}[/tex]

Explanation:

• Speed, time and distance is one of the most common and important topics in the Mathematics or Quant section.

• Calculate total speed;

[tex]\therefore \text { Total Speed }=2+0.5+0.0+1=3.5 \mathrm{~m} / \mathrm{sec}[/tex]

• Calculate total time taken;

[tex]\therefore \text { Total time taken }=120+30+40+14400=14590 \mathrm{sec}[/tex]

• To find total travelled distance, use the formula

[tex]\text { Distance }=\text { Speed } \times \text { Time }[/tex]

[tex]\mathrm{d} &=3.5 \times 14590 \\[/tex]

[tex]&=51065 \mathrm{~m}[/tex]

Answer: This is because sharks are pregnant for 6 months to 2 years. Which decreases shark population due to slow birth rates. This also effects female sharks health die to the stress of carrying many sharks for up to 2 years. Most sharks die before or after giving birth. Overfishing for sharks is rapidly decreasing the shark population due to slow breeding but many fisherman. Less females and males are able to mate and sharks are pregnant for so long that the female has a high percentage of getting caught. In the long run more and more sharks are being killed each year which decreases sharks population for obvious and non obvious reasons.

Explanation:

Answer:

Until recently, most neuroscientists thought we were born with all the neurons we were ever going to have. As children we might produce some new neurons to help build the pathways - called neural circuits - that act as information highways between different areas of the brain. But scientists believed that once a neural circuit was in place, adding any new neurons would disrupt the flow of information and disable the brain’s communication system.

In 1962, scientist Joseph Altman challenged this belief when he saw evidence of neurogenesis (the birth of neurons) in a region of the adult rat brain called the hippocampus. He later reported that newborn neurons migrated from their birthplace in the hippocampus to other parts of the brain. In 1979, another scientist, Michael Kaplan, confirmed Altman’s findings in the rat brain, and in 1983 he found neural precursor cells in the forebrain of an adult monkey.

These discoveries about neurogenesis in the adult brain were surprising to other researchers who didn’t think they could be true in humans. But in the early 1980s, a scientist trying to understand how birds learn to sing suggested that neuroscientists look again at neurogenesis in the adult brain and begin to see how it might make sense. In a series of experiments, Fernando Nottebohm and his research team showed that the numbers of neurons in the forebrains of male canaries dramatically increased during the mating season. This was the same time in which the birds had to learn new songs to attract females.

Why did these bird brains add neurons at such a critical time in learning? Nottebohm believed it was because fresh neurons helped store new song patterns within the neural circuits of the forebrain, the area of the brain that controls complex behaviors. These new neurons made learning possible. If birds made new neurons to help them remember and learn, Nottebohm thought the brains of mammals might too.

Other scientists believed these findings could not apply to mammals, but Elizabeth Gould later found evidence of newborn neurons in a distinct area of the brain in monkeys, and Fred Gage and Peter Eriksson showed that the adult human brain produced new neurons in a similar area.

For some neuroscientists, neurogenesis in the adult brain is still an unproven theory. But others think the evidence offers intriguing possibilities about the role of adult-generated neurons in learning and memory.

Answer:

While pathogenic bacteria are notorious for such diseases as cholera, tuberculosis, and gonorrhea, such disease-causing species are a comparatively tiny fraction of the bacteria as a whole.

Answer: It is the cell membrane will change and unsaturated fatty acids replace saturated.

Explanation:

Because unsaturated fatty acids have a kink, substituting unsaturated fatty acids for saturated fatty acids in the cell membrane of winter wheat is a suitable adaptation for the increased fluidity present in Option A.

Cell membranes are composed of a lipid bilayer, which is made up of two layers of phospholipid molecules and consists of lipids such as saturated and unsaturated fatty acids that differ in their chemical structure, Saturated fatty acids have no double bonds between the carbon atoms in their hydrocarbon chains, while unsaturated fatty acids have one or more double bonds that provide fluidity to the plasma membrane.

Hence, substituting unsaturated fatty acids for saturated fatty acids in the cell membrane of winter wheat is a suitable adaptation for the increased fluidity present in Option A.

Survival of the fittest shows that plants/animals with traits better suited for survival in their environments usually pass those traits to their offspring to help them survive.

Cactus plant with these traits were better able then other cactus plant to survive and pass these traits on to their offspring.

Stems that can store water. Widespread or very deep root systems that can collect water from a large area or from very deep underground.

Cactus is found in dry and hot areas where rainfall is minimal and the land is arid. Their leaves are evolved into thorns to prevent transpiration and they can store water inside them.

12K is the boiling point of the chemical .

The boiling point of any liquid changes to the applied pressure the normal boiling point is the temperature at which the vapor pressure is equal to the standard sea-level atmospheric pressure .At sea level, water boils at 100° C (212° F).The boiling point of a liquid is the temperature at which its vapor pressure is equivalent to the pressure of the gas above it.

Boiling point is used to identify and classify a given compound. A liquid boils when its vapour pressure is equal to the atmospheric pressure. Vapour pressure is also defined  by the kinetic energy of a molecule. Kinetic energy is dependent on the temperature, mass and velocity of a molecule.

Conservation ecology is the branch of ecology and evolutionary biology that deals with the preservation and management of biodiversity and natural resources. Its goal is to find ways to conserve species, habitats, landscapes, and ecosystems as quickly, as efficiently, and as economically as possible.

-These are some examples of how we can conserve the environment:

Recycle your rubbish and participate in or help organize recycling campaigns.

Avoid littering and participate in or help organize litter clean-ups (here you can link to a website for volunteering or starting your own beach clean-up).

Use less plastic by, for example, carrying a reusable water bottle, saying no to disposable straws and cutlery, avoiding plastic toys, and bringing your own shopping bags (for further ideas on a plastic-free life take a look here).

Swap toys, movies, and books instead of buying new ones.

Donate, recycle, and repair electronic devices (see how here).

Use less water when brushing teeth, taking a shower, or washing the dishes.

Use less electricity by turning off lights and electronic devices when not in use, using energy-saving light bulbs, and hanging clothes to dry.

Use public transport, share a journey with friends (e.g., car-sharing), cycle, or walk when possible.

Use less paper by not printing unnecessary things and reading e-books.

Turn down the air conditioning when it is hot and use fans if you are still hot-they use much less power.

Turn down the heat when it is cold and use sweaters, blankets, and socks to keep warm.

Do not waste food and try to buy food that is grown locally and in season.
