Why is the frogs tongue anchored in the very front

Answers

The frog's tongue is being anchored in the very front of its mouth instead of attaching it in its back. Its tongue is anchored in front in order to make hunting for prey easier because the from needs to throw its tongue to capture its food then throw the food back to its mouth.

It`s anchored at the front instead of the back so it can catch it`s own prey easier. It developed this characteristic over time so they wouldn`t die off. By having their tongue anchored at the front, frogs can throw out their tongue easier.

Which of these is always part of using the scientific method?

Answers

Since you provide no options, here are the usual parts of scientific method :

- Idea / question which answer you want to find out
- Research , collecting all kinds of data
- Hypothesis , an explanation that is made at the starting point, before the experiment
- Experiment , to find out whether your hypothesis is right
- Analyze the data that you got from the experiment
- Conclusion, your final judgement based on the result of your experiment

Chemical reactions carried out by living systems depend on the ability of someorganisms to capture and use atoms from nonliving sources in the environment.
The specific subset of these reactions that break down nutrients in food can be
described as _____________.
(a) metabolic.
(b) catabolic.
(c) anabolic.
(d) biosynthetic.

Answers

Answer:

(B) Catabolic.

Explanation:

The metabolism refers to the chemical reactions which are used by the organisms to sustain their life therefore metabolism is considered a characteristic feature of the living organisms.

The metabolism involves either the formation of a molecule from the smaller subunits or monomer through a process known as anabolism and other involves the breakdown of the larger molecule into smaller subunits through catabolism.

In the given question, the breakdown of the food particle which is usually the complex biomolecules is broken down into simpler subunits through a catabolic reaction. The smaller subunits of molecules are easily absorbed ad then utilised by the body.

Thus, Option-B is the correct answer.

All algae except for diatoms can conduct photosynthesis.
a. True
b. False

Answers

The answer is false.Diatoms are a major group of algae. They are mainly photosynthetic. However, there are few that are obligate heterotrophs while there are others that can live heterotrophically in the absence of light, an appropriate organic carbon source is available.

What is an important characteristic of the plant cell wall?a. It is fluid.
b. It is rigid.
c. It is alive.
d. It stretches.gy

Answers

The best answer is b - it is rigid.

The cell wall is defined as the rigid, outermost layer found in plants and also certain bacteria, algae and fungi. It is absent in animal cells.

The plant cell wall is made up cellulose which is a structural carbohydrate. The cell wall is rigid and thus offers structural support allowing plant such as trees to grow to great heights.

It also helps prevent water loss, helps protect against insects and pathogens and keeps the shape of the plant.
