Which type of macromolecule contain high energy bonds and is used for long term energy storage

Answers

Answer 1
Answer:

Answer:

Lipids.

Explanation:

Lipids are compounds with varied molecular structure, presenting several organic functions: energy reserve (energy source for hibernating animals), thermal insulator (mammals), in addition to collaborating in the composition of the plasma membrane of cells (phospholipids).

Lipids are molecules that contain high-energy bonds and are used for long-term energy storage. They can be classified into oils (unsaturated substances) and fats (saturated substances), which are found in foods of both vegetable and animal origin, as well as in fruits (avocado and coconut), soy, meat, milk and its derivatives and also in the egg yolk.

In general, all living things are capable of synthesizing lipids, however, some classes can only be synthesized by vegetables, as is the case with fat-soluble vitamins and essential fatty acids.

Answer 2
Answer:

Lipid functions:

Stores energy; forms parts of biological membranes and waterproof coverings.

Which type of wave helps astronomers to determine the hottest stars?

Answers

Blue wave helps astronomers to determine the hottest stars.

What is blue wave?

Managing technological requirements, vetting service providers, assessing proposals, and tracking continuous solution optimization can be costly, time-consuming, and difficult.

The Bluewave Technology Lifecycle Management Approach is a client-focused approach to assessing, sourcing, managing, and supporting technology solutions that can encompass a wide range of suppliers from dozens of screened, approved possibilities.

When sunlight enters the atmosphere of Earth, all the gases and airborne particles scatter it in all directions. Because blue light travels as shorter, smaller waves than the other hues, it scatters more than the other colors.

Therefore, Blue wave helps astronomers to determine the hottest stars.

To learn more about blue waves, refer to the link:

#SPJ2

Answer:

Blue Wave (620–680 THz).

Explanation:

In the electromagnetic spectrum are plenty of different waves that change their properties according with their length, energy, frequency. In this case, the hottest stars are the blue ones, because this means that they are spreading waves with a major frequency and, for instance, major energy, which means major hot.

List 3 examples of a selectively permeable material or item. Explain where it is found or used and why a selectively permeable item is needed

Answers

Answer;
Examples of selectively permeable materials or items are; 
1. Vacuum filter- it traps dust but allows air through
2. Coffee filter- allows water to pass through, but does not allow the coffee grounds.
3. Colander -used to strain liquid food from foods. it drains water but is not permeable to larger food particles.

Explanation;
Selective permeability means that a material or a substance allows the passage of some molecules or ions and other materials to pass through it, and inhibits the passage of others. 
For example a cell membrane is semi-permeable and thus regulates the transport of materials such that some particles pass through while others can not cross. A semi-permeable membrane allows selective movement of materials, it acts like a filter that allows particles to pass or not according to their size, solubility, electrical charge, or other chemical and physical properties. 

I have this question for homework as well.
Colander - drains water but isn't permeable enough to lager food (used to strain liquid from food)
Vacuum filter - traps dust but allows air through (used to clean)
Coffee filter - allows air through (used to make coffee)



Which best characterizes the Precambrian era?A.


abundant plants and animals


B.


dinosaurs


C.


small, one-celled organisms and primitive jellyfish


D.


extensive mountain building

Answers

the answer is dinosaurs

Answer:

It is C

Explanation:

Because everything's starts out small and they are the smallest in the eras because one cell turns to two cells and etc. it was the beginning of all life forms . It couldn't be dinosaurs because they were in the Mesozoic era. At the time of the Precambrian  era i think it was before the Phanerozoic eon

In what ways does the water cycle provide fresh water around earth

Answers

The water cycle provides fresh water by evaporating salt water because salt can't be picked up when evaporated so you have fresh water in the sky. When it rains, it spreads the water around into groundwater, lakes, steams, etc. 
The rain, I mean ; when the water evaporates from seas or big lakes, it goes into clouds and those clouds form RAIN If that PLACE (Like Africa) doesn't has water, it won't rain Did it helped??

Question 12After many cell divisions, a segment of DNA has more base pairs than it originally did. Explain what has happened.

Can you please help me with this, that'd be great! Thanks!

Answers

The correct answer is insertion mutation.

The mutation is defined as the change in the DNA (deoxyribonucleic acid) sequences. The insertion mutation is a type of mutation, in which the insertion of the nucleotides takes place in the DNA sequences, resulting in an increase in the total number of base pairs in the DNA sequence. So, the insertion mutation has resulted in the increase in the base pairs in this case.  

Its because they keep replicating say you start 0ff with then it will keep doubling for example 2,4,8,16,32,64,128,256,512,1024 hope this helps
