Answer:

If you want to calculate the wavelength of a wave, then all you have to do is plug the wave's speed and wave's frequency into the equation. Dividing speed by frequency gives you the wavelength. For example: Find the wavelength of a wave traveling at 20 m/s at a frequency of 5 Hz.

The wavelength of a wave can be calculated with the help of frequency and speed of wave. Wavelength is the ratio of speed of wave and the frequency of wave.

A wave is a disturbance in the medium which carries energy without a net movement of particles. It may take the form of the elastic deformation, a variation of the pressure of the waves, electric or magnetic intensity, electric potential, or temperature.

The wavelength of the wave can be calculated with the help of the speed of wave and the frequency of wave.

Wavelength = Velocity of the wave/ Frequency of the wave

λ = v/ f

Answer: Warmer water temperatures can result in coral bleaching. When water is too warm, corals will expel the algae (zooxanthellae) living in their tissues causing the coral to turn completely white. This is called coral bleaching.

Explanation:

Answer:

its Hey now children, settle down. Today we're going to talk about life. There are six ways to know you're alive for sure:

1. Living things have cells.

2. They use stimuli to maintain a homeostasis.

3. They have DNA.

4. They reproduce.

I said no laughing!

5. They live, thrive and die.

6. They use energy.

Ayo, first things first:

There's three different types of living things on the Earth.

Ya heard?

There's organisms with one cell,

Whose life functions are performed by organelles.

And green plants use photosynthesis,

A chloroplast converts sunlight and lives with it.

And last are the animals, listen,

Cells, tissue, organ-to-organ system.

And they're unique; I can't lie, homes,

Only animal cells contain lysosomes.

But all cells contain ribosomes.

They make proteins, the building blocks, I suppose.

Yo, but don't get caught slipping

On the oils and the fats, a.k.a. the lipids.

Cells need fuel — they break carbohydrates

Into ATP, adenosine triphosphate.

Alright y'all! Cell theory has three parts:

1. All living things are composed of one or more cells.

2. The cell is the basic unit of life in all organisms.

3. All cells come from existing cells.

On top of that, they all have a cell membrane surrounding the cytoplasm, and most plants and bacterium have a cell wall.

Now let's travel to the center of the cell,

The nucleus, where nucleic acids are held.

They form DNA, the genetic code,

And multiply by mitosis if you let it go.

It's incredible, like the duty is

Of mitochondria — extract energy from nutrients.

And did I mention, the spot they make the lipids in,

Is the ER, or endoplasmic reticulum?

And the Golgi complex is next to it,

Delivering the products of the ER — excellent!

To hit the exit, you could use diffusion,

The membrane will pass in or out of solution.

Of all movement, the cell has control,

Disposing of waste in a vacuole.

And that can use active transport,

To either squeeze out or ingest something, so plan for it.

Alright y'all! Now who in here can spell flagella? And who knows where the word came from, "cell"? Anybody know that it's Latin? Cellula means "small room." Now before y'all go, let me remind you: Don't forget to respect the building block of life. Give it up for cells, y'all! Alright, class dismissed. Class dismissed. Get your flagella out of here.

Answer:

Factors such as pollution, the depth at which both birds go down to catch the fish (if you look at experiments populations of fish tend to deplete quicker when in a shallow depth than a deeper depth), another factor would be the use of mammals fishing for food- this factor can range from a bear all the way down to humans taking huge quantities of fish in from the sea.

These are only a few factors I could genuinely think of.

Answer:

Cancerous tissue.

Explanation:

Cancerous tissue would have a higher mitotic index because the cells are constantly dividing.

Uracil will be transformed back into Thymine in a DNA Strand.

Adenine (A) and Thymine (T) are base-pairs, and will not pair to Cytosine or Guanine.

Guanine (G) and Cytosine (C) are base-pairs, and will not pair to Adenine or Thymine (or Uracil in RNA).

People living with type 1 diabetes must inject insulin regularly, as must some people with type 2 diabetes. Many people with type 2 diabetes can manage their condition with careful diet, exercise and regular testing.

Until recently almost all children and teenagers with diabetes had type 1, but now younger people are getting type 2 diabetes due to increasing rates of obesity and being overweight.

Answer:

C) Radio waves are used to transmit television and radio  programs.

Explanation:

Radio wave is a form of electromagnetic radiation which is used in communication technologies, such as radio, television, and mobile phones. Communication technologies or devices receive radio waves and then they are converted into mechanical vibrations in the speaker that creates sound waves.

Hence, the correct answer is "C) Radio waves are used to transmit television and radio  programs."

Answer:

According to the hormone diagram of the menstrual cycle, the woman is not pregnant due to the behavior of progesterone and estrogens, whose levels do not increase, in addition to the absence of human chorionic gonadotropin.

Explanation:

The graph shows the behavior of hormones during a woman's menstrual cycle in the absence of pregnancy.

During a woman's normal cycle, estrogen, luteinizing hormone (LH) and follicle stimulating hormone (FSH) tend to increase prior to ovulation, reach their peak values at ovulation, and then decline, as shown in the graph. Progesterone, on the other hand, increases after ovulation and decreases if the woman does not become pregnant.

In the case of a pregnant woman:

The diagram represents the normal cycle of a woman who is not pregnant.

Ginkgo has the least amount of species diversity out of all gymnosperms.This gymnosperm's ancestors are so ancient it is sometimes called the "living fossil tree."

The cycads, gnetophytes, and conifers have many genera and various species, but there is only one species in the one sole Ginkgo genus, the Gingko biloba. This gymnosperm holds the record for the largest tree in the world.

The Gingko biloba presents the only surviving species of a previously widespread and diverse spread genus Ginkgo.This gymnosperm's ancestors are so ancient it is sometimes called the "living fossil tree"

Therefore, Ginkgo has the least amount of species diversity out of all gymnosperms.This gymnosperm's ancestors are so ancient it is sometimes called the "living fossil tree."

Answer: true

Explanation:

Answer:

The air over the ocean is now warmer than the air over the land. The land loses heat quickly after the sun goes down and the air above it cools too. ... This causes a small temperature gradient between the ocean surface and the nearby land at night and the wind will blow from the land to the ocean creating the land breeze.

It Considered to be a high mass star

Explanation:

High mass stars go through a similar process to low mass stars in the beginning, except that it all happens much faster. Then unlike low mass stars, they have enough mass that gravity contracts the core raising the temperature and carbon can fuse into neon, then neon into oxygen, then oxygen into silicon, then iron.

Answer:preventing or reducing pollution from the land and from streams

Explanation: This is true because these said streams and other bodies of water can flow into the ocean

The key to protecting the oceans is preventing or reducing pollution from the land and from streams is reducing population growth along the coastline. The correct option is A.

Pollution is the release of potentially harmful substances into the environment. These potentially damaging compounds are referred to as pollutants.

Despite the fact that metropolitan areas are often more polluted than the countryside, pollution can nonetheless migrate to isolated locations where no one lives.

For instance, it has been demonstrated that the Antarctic ice sheet contains chemicals and pesticides. The Northern Pacific Ocean's Great Pacific Garbage Patch is a vast collection of little plastic waste.

Therefore, the correct option is A, reducing population growth along the coastline.
