what physical feature of dna is affected by the pairing of purines with pyrimidines?

Answers

Answer 1

Answer:

Its width.

Explanation:

The size of pyrimidines and purine is different because each group has a different structure (1 or two rings). Therefore, the width of DNA is "constant".

If we would pair two pyrimidines or two purines, the width of DNA would be different in both cases.

The word matrix can be used to describe things shaped In a pattern of lines and spaces. How does this relate to a mitochondrion?

Answers

The definition of the word matrix can be applied to the organelle known as mitochondria given that the mitochondria have what is known as a "mitochondrial matrix".

The mitochondria are amongst the most important organelle of a cell. They are responsible for the production of energy molecules in the form of ATP. The basic structure of mitochondria consist of:

Outer membraneIntermembrane spaceInner membrane MatrixGranules

and contain even more elements within.

The inner membrane of the mitochondria surrounds the matrix, giving it the form of a pattern of lines that bend and curve, leaving spaces in between. The similarity between this shape and the definition that is given of the word "matrix", explains why this structure may have been given the name of the mitochondrial matrix.

how do I write the equation P^2 = kA^3, so that I'm solving for the variable K?

Answers

Answer:

k = (P^2)/(A^3)

Explanation:

Step 1: Flip the equation.

[tex]kA^3 = P^2[/tex]

Step 2: Divide both sides by A^3.

[tex]\frac{kA^3}{A^3} = \frac{P^2}{A^3}[/tex] [tex]k = \frac{P^2}{A^3}[/tex]

Therefore, the answer is [tex]k = \frac{P^2}{A^3}[/tex].

In science, the term theory is applied only to ideas that are supported by a vast, diverse array of evidence. How is the term used in everyday life?

Answers

Answer:

It explains facts and allows people to make predictions.

Explanation:

In everyday life, the word theory often means an untested hunch, or a guess without supporting evidence. A theory not only explains known facts but also allows scientists to make predictions of what they should observe if a theory is true.

In science, the term theory is applied only to ideas that are supported by a vast, diverse array of evidence. The term is also used in everyday life based on personal beliefs which does not support any strong evidence.

What is scientific theory?

In science, a theory is a term applied to a well-explanation of an aspect of the natural world on the basis of empirical evidence that has undergone rigorous testing and evaluation. The process involves collecting and analyzing data and observations and hypotheses are based on the data obtained which form the basis of scientific theory. Therefore, scientific theory is an explanation that has been verified by scientific researchers.

However, the term theory is casually used in everyday language without any scientific proof. For example, someone may say "I have a theory that the universe fake". This fact is casually spoken by a person which is not based on any scientific fact.

Scientific theories are based on evidence supported by rigorous testing, while everyday theories are based on personal beliefs without any strong evidence.

Therefore, the term theory is also used in everyday life, which is based only on a personal belief, and not only on any scientific fact.

In adult men , 60% of body is comprised of water whereas in women , 55% of body is comprised of water.

Protein makes up around 20% in body and is present in every cell.

What are Proteins?

Proteins are large complex molecules and play critical roles in the body. They do most of the work in their cells and required for structure functions and regulation of body tissues.

Proteins are made up of smaller units called amino acids, which are attached to one another in long chains.

There are 20 different types of amino acids that can be combined to make a protein.

The sequence of amino acids determines about each protein’s unique 3-dimensional structure and its specific function.

Amino acids are coded by combinations of three DNA building blocks (nucleotides), determined by the sequence of genes.

Functions of Proteins:

1. As an Antibody-  Bind to specific foreign particles such as bacteria and virus to help protect the body.

2. As an Enzyme- Carry out thousands of chemical reactions taking place inside the cell

3. As a Messenger- Transmit signals to coordinate biological processes between different cells, tissues and organs.

4. As a Structural Component- Providing structure and support to cells.

5. Transport/Storage- Binding and carrying atoms and small molecules within cells and throughout the body.

The main reason why land is being destroyed is because we keep damaging it, also got it right on the test

They protect land from human development is more effective at reducing destructive use of forests. The correct option is D.

Thus, Regulations governing restricted-use land are more effective at halting the destruction of forests because they shield the area from habitation.

These laws place restrictions on how the property can be used, prohibiting actions like logging, mining, and building that could seriously damage the forest ecology.

Restrictive use laws support the preservation of the natural ecosystem, biodiversity, and general health of the forest by stopping or limiting these damaging behaviours.

Thus, They protect land from human development is more effective at reducing destructive use of forests. The correct option is D.
