Answer:
Ribosomes.
Explanation:
The function of ribosomes is to make protiens by joining amino acids together.
The new hydrophilic amino acid would not form the same interactions with hydrophobic R groups. As a consequence, protein's 3D structure would likely be affected.
Different types of amino acids have different properties and thus form different interactions. For example, hydrophobic amino acids (water-repelent) such as alanine, valine, leucine, isoleucine, proline, phenylalanine, cysteine and methionine. participate in van der Waals type of interactions. They often form the hydrophobic core of the protein which doesn’t interact with water surrounding.
On the other hand, hydrophilic amino acids (arginine, asparagine, glutamine, aspartat..) are polar, can dissolve in the water and can join the hydrogen bond network.
The correct statement is :
Excretory system excretes waste materials from the body and is very important for homeostasis.
Answer: True
Explanation:
The given statement is true that the waste material that is produced inside the body needs to be excreted out.
This is an important part o the homeostasis that the waste should be excreted out of the body on time. This helps in maintaining equilibrium inside the body.
If the waste material are not excreted outside the body and remains inside the body then it cause disease inside the body.
So, the correct answer is True.
Biomass is the most used renewable source of energy in US in the year of 2009.
<h3><u>
Explanation:</u></h3>
In US, the country is very cold and use of wood and other plant products as chimney fuels, or in cooking and other purposes are very common. This is because being a temperate country, US has forests of conifers which are source of soft wood, ideal for burning.
Other sources of Biomass energy comes from the biogas, wood wastes, ethanol, municipal solid wastes and even biodiesel.
As a present day scenario, although coal and petroleum are still the most used fuels in US, but the use of renewable sources of energy has increased to twice the amount from 2010 to 2018.
