What is the difference between El Nino and La Nina in science terms of climate?
Answer:
El Niño impacts weather systems around the globe, triggering predictable disruptions in temperature, rainfall and winds. La Niña is the opposite – a cooling phase of ENSO that tends to have global climate impacts opposite to those of it. El Niño refers to the above-average sea-surface temperatures that periodically develop across the east-central equatorial Pacific. It represents the warm phase of the ENSO cycle. La Niña refers to the periodic cooling of sea-surface temperatures across the east-central equatorial Pacific.
Hope this helps
Answer:
Well, El Niño(warmer environment) impacts weather systems around the world, while La Nina(cold environment) tends to have global climate affects opposite to El Nino.

Which of the following is NOT something that can cause your core temperature to change?
Question 1 options:
Fevers caused by disease
Enzymes denaturing in your cells
When the external temperature gets really hot or cold
Energy produced by your muscles when you exercise
Question 2 (1 point)
Why is it so important to maintain a core temperature of 37°C?
Question 2 options:
Your core temperature doesn't stay at 37°C, it will actually change and reflect the temperature outside.
Your body can only make cells at 37°C, and we need cells because that is what our body is made of.
It is just best to keep that temperature so you don't shiver or sweat.
The enzymes in our cells work best at this temperature and these enzymes are needed to carry out all the reactions that happen in our body to keep us alive.
Question 3 (1 point)
What happens to your enzymes when they get too hot?
Question 3 options:
The enzymes denature and the active site alters, so the substrate can't fit in there properly and chemical reactions don't happen as fast.
The enzyme changes shape, but the substrate still fits in and the chemical reaction can still take place.
The enzyme dissolves and the pieces then need to be rebuilt before they can be used again.
Nothing, the enzyme can handle temperature changes in the body.

Which of the following best describes how your muscular and skin systems work to warm you up if you get too cold?
Question 6 options:
Your muscles begin to contract fast and this movement helps you warm up
Small erector muscles work to raise the hairs on your skin. This helps trap the air close to the skin, goose bumps appear and the air acts as an insulator
blood vessels narrow keeping the blood away from the skin to keep you warm
Sweat glands release sweat to ensure you stay the proper temperature
Question 7 (1 point)
Which of the following best describes how your circulatory and skin systems work together to cool you off when you get too hot?
Question 7 options:
Your blood vessels (capillaries) dilate allowing blood to flow near the surface of your skin. This allows the heat to be released through your skin to help you cool off.
You begin to sweat which leaves salt on your skin after the sweat evaporates.
The hairs on your skin will lie flat to allow better evaporation of sweat and to allow the heat to be released into the air
Goose bumps show up to help your muscles contract to help cool you off

Skeletal muscle exhibits alternating light and dark bands called a sarcomere
Skeletal muscle is having sarcomere having myofibrils which appear dark and light in the microscope.
What is skeletal muscle?Only thin filaments containing actin are present in isotropic bands, anisotropic bands are the darker bands (A bands).
Repeating sarcomere sections, which are visible under the microscope as alternating dark and light bands, make up myofibrils.
When a muscle contracts or relaxes, long, fibrous protein filaments called sarcomeres glide past one another. Because of this, skeletal muscle is also known as striated muscle.
Therefore in appearance due to myofibrils composed of the sarcomere look light and dark bands in the skeletal muscle under a microscope.

Explanation:
Basic Biology
BASIC BIOLOGY
Inspired by life
TRANSCRIPTION AND TRANSLATION
Genes provide information for building proteins. They don’t however directly create proteins. The production of proteins is completed through two processes: transcription and translation.
Transcription and translation take the information in DNA and use it to produce proteins. Transcription uses a strand of DNA as a template to build a molecule called RNA.
The RNA molecule is the link between DNA and the production of proteins. During translation, the RNA molecule created in the transcription process delivers information from the DNA to the protein-building machines.
DNA → RNA → Protein
DNA and RNA are similar molecules and are both built from smaller molecules called nucleotides. Proteins are made from a sequence of amino acids rather than nucleotides. Transcription and translation are the two processes that convert a sequence of nucleotides from DNA into a sequence of amino acids to build the desired protein.
These two processes are essential for life. They are found in all organisms – eukaryotic and prokaryotic. Converting genetic information into proteins has kept life in existence for billions of years.
DNA and RNA
RNA and DNA are very similar molecules. They are both nucleic acids (one of the four molecules of life), they are both built on a foundation of nucleotides and they both contain four nitrogenous bases that pair up.
A strand of DNA contains a chain of connecting nucleotides. Each nucleotide contains a sugar, and a nitrogenous base and a phosphate group. There is a total of four different nitrogenous bases in DNA: adenine (A), thymine (T), guanine (G), and cytosine (C).
A strand of DNA is almost always found bonded to another strand of DNA in a double helix. Two strands of DNA are bonded together by their nitrogenous bases. The bases form what are called ‘base pairs’ where adenine and thymine bond together and guanine and cytosine bond together.
Adenine and thymine are complementary bases and do not bond with the guanine and cytosine. Guanine and cytosine only bond with each other and not adenine or thymine.
There are a couple of key differences between the structure of DNA and RNA molecules. They contain different sugars. DNA has a deoxyribose sugar while RNA has a ribose sugar.
