Which statement best describes the effect of the low density of frozen water in a lake

Biology
1 answer:
Arada [10]3 years ago
4 0

Answer:

Explanation

Water in a lake freezes from the bottom up, killing most aquatic organisms. When water in a lake freezes, it floats, providing insulation for organisms below. ... If water were most dense as a solid, lakes would freeze from the bottom up, eventually freezing solid.

defon

Answer:

As i am asked to lead a research team to observe gorillas in their natural environment I will prefer a team having persons expert in having knowledge of forest in which we are doing research on gorillas. They must be experience in working with gorillas and familiar with their nature.

My team should have a person who know to use the tranquilizer gun because to collect the DNA sample gorilla needs to be tranquilized. My team should have one veterinary doctor who can examine the animal and take the DNA sample.

People with Good communication skills, observation skills and critical thinking skills are required in the team to successfully complete the research.

10 points! When looking out of my back door, I see robins, blue jays, finches, crows, hawks and owls all living in the same area
forsale [732]

The possibility for all of the mentioned birds to live all in a same area is because they are all specialized and occupy a certain niche in the food chain, thus not standing in each others ways when it comes to competition for food.

All of these birds have adapted to be able to survive in their respective environment, developing characteristics that will enable them to be superior in something. Through natural selection, the individuals that were performing better, got the chance to mate, thus the offspring was better adapted and stronger in its niche of the food chain.

The robins and the blue jays are birds that are very opportunistic in their food choice, thus giving them greater flexibility and ability to survive, they mostly feed on worms, insects, fruits, vegetables, so they have a big menu.

The finches are specialized in eating nuts and seeds, thus avoiding the competition with the previous two, thus having that food type for themselves.

The owls and hawks are both birds of pray, but the owls hunt mostly at night, while the eagles during the day. Also, the owls prefer to have rodents as their pray, while the hawks are mostly eating other birds, thus not standing in each other's ways.

What is the Mechanical energy when
Scilla [17]

Answer:

ME = 20 * m, where m is the mass of the pendulum

Explanation:

As we know that mechanical energy is the sum of kinetic energy and potential energy.

Since the Pendulum at its highest point has zero velocity, its kinetic energy at this point is equal to zero.

Thus, here in this mechanical energy will be equal to the potential energy only.

Potential energy is equal to the product of gravity constant, mass of the body and the height of the pendulum

Thus,

ME = PE\\

PE = m * g* h\\PE = 10 * 2* m\\

PE= 20m

Hence,

ME = 20 * m
