What are some terms you can use to describe the size and shape of a bird's beak ?

Answers

The beak of the birds varies in sizes and shape. Its purpose is for feeding. The shape accords to what the bird eats. Here are some of the terms you can describe a bird's beak:

* cone shaped bill
* pointed beaks
* strong beaks
* long beaks
* sharp beaks
* thin beaks
* slender beaks
* tubular beaks
* hooked beaks

Answer:

Size can be defined by words such as - long , short

Shape can be defined by words such as - curved, hooked, slender, sharp etc.

Explanation:

The shape and size of beak depends on the purpose of is usage.

Hence,  the following terms can be used to describe the size and shape of a bird's beak -

1. Birds which prey their food have hooked beaks  which are strong and deep to make a firm catch on their food

2. Birds which feed on fruits have  sharp beaks

3. Birds which feed on fish have long, sharp and slender beak

4. Birds feeding on seeds have short and curved beaks

Small aquatic organisms, such as coral, are the producers of the ocean. true or false

Answers

This statement is true. Small aquative organisms like coral are the producers of the ocean, because they do not to feed upon other organisms to survive and they themselves produce oxygen which is needed in the water.

Where does a peptide bond form?

Answers

A peptide bond is a chemical bond formed between two molecules when the carboxyl group of one molecule reacts with the amino group of the other molecule, releasing a molecule of water (H2O). This is a dehydration synthesis reaction (also known as a condensation reaction), and usually occurs between amino acids.

Which kingdoms contain organisms that are prokaryotes?

Answers

Answer: The two prokaryotic kingdoms are Eubacteria and Archaea.

Explanation:

The kingdoms that contains organisms that are prokaryotes are Bacteria and Archaea. They are unicellular kingdoms and their members appear similar in shape and appearance. But, they are different from each other and that is why they are grouped into separate kingdoms. Bacteria are all known as prokaryotes, which are organisms that lack a cell nucleus and other membrane-bounds organelles, and tend to be less complex. Archaea does not have membrane-bound organelles either but they have a cell wall that does not contain peptidoglycan (which is found in Bacteria) and cell membrane uses ether linked lipids as opposed to ester linked lipids in bacteria.

Farah is doing an experiment that involves calculating the speed of a longitudinal wave. What will most likely happen if she increases the temperature in the room?

Answers

The speed of a longitudinal wave will not be affected by the temperature of its surrounding. Base on the formula for the wave speed (applicable on longitudinal wave), wave speed ( speed in m.s 2) is equal to the distance of a wave (wavelenth in meter) travel over a unit of time  (seconds) or wave speed is equal to distance of a wave times the frequency (hertz), temperature is not included in calculating the wave speed.

Explanation:

In the given problem, Farah is doing an experiment that involves calculating the speed of a longitudinal wave

For example, Sound wave is a longitudinal wave. It travels faster in solid than liquid and gas as the solid is more denser.

The speed of the sound increases with the temperature. At higher temperature, the molecules have more kinetic energy. They can vibrate faster. The sound wave can travel faster. The speed of the sound in the room temperature is 346 m/s.

If Farah increases the temperature then the sound wave travels faster.
