What transformation takes place wen u light up a match
Answer:
Transformation that happens when you strike a match is from mechanical energy to thermal energy.
Explanation:
When you strike a match, it moves through the air until it rubs against a surface. The rubbing produces the heat required to light the match. (Thermal energy is heat energy)
Answer:
mechanical energy to thermal energy.
Explanation:
When the match is struck, it burns and the chemical energy in it produces heat energy and light energy
When you strike a match, it moves through the air until it rubs against a surface. The rubbing produces the heat required to light the match. This is a transformation from mechanical energy to thermal (heat) energy.

Explanation:
after death, the cornea absorbs fluid and becomes opaque. in a living person, the cornea is translucent due to _______________.
Given what we know about human anatomy, we can confirm that the cornea of a live human is translucent due to the arrangement of its collagen fibers and the lack of vascularity.
One important factor in the translucent nature of the cornea and lens is its lack of vascularity. This area of the eye has few if any vascular components, which contributes to its lack of pigment.
However, the main component that contributes to the translucent nature of the human cornea is its very specific arrangement of collagen fibers.
The bundled nature of these fibers, together with the water content of the cornea, allow it to remain translucent.

Which statement about biochemical reactions is false?
The statement that is false is that they can create new energy during the reaction. The correct option is a.
What is biochemical reaction?Biochemical reactions are chemical processes that occur in live cells to support life and promote cell growth.
To expedite most biochemical reactions, an enzyme is a type of biological catalyst.
The amount of activation energy required for the reaction to start is decreased by enzymes. Most enzymes are proteins that only interact with one particular chemical, known as their substrate.
The ratio of atoms in the reactants and products must always be balanced.
They have the capacity to store energy as a covalent bond. They have the ability to alter the cell's energy's shape. They follow the laws of physics and chemistry.
Thus, the correct option is a.

Mendel knew that the variations in the offspring generations resulted from his experiments because he
Mendel was able to attribute the variation observed in the offspring of his experiment to the controlled fertilization process.
Mendel was able to control pollination and, thus, the fertilization process in the pea plants used for his experiment.
Mendel was able to effectively predict the outcome with self-pollination or cross-pollination with different results coming from each. Thus, he logically concluded that the variation observed in the offspring of his crosses is due to the fact that he controlled the fertilization process.

Why do the alveoli fill with fluid.
Answer:
Your lungs contain many small, elastic air sacs called alveoli. With each breath, these air sacs take in oxygen and release carbon dioxide. Normally, this exchange of gases occurs without problems. But sometimes, the alveoli fill with fluid instead of air, preventing oxygen from being absorbed into your bloodstream.
Explanation:
Answer:
The fluid represents the outermost layer of the alveolar surface that is directly exposed to air and thus to the environment. Alveolar fluid prevents desiccation of the epithelial cells and also functions as a physical protection barrier against inhaled particles and irritants. Explanation: hope this helps

a bacterium is infected with an experimentally constructed bacteriophage
The complete question is:
a bacterium is infected with an experimentally constructed bacteriophage composed of the T2 phage protein coat and T4 phage DNA. The new phages produced would have
A) T2 protein and T4 DNA
B) T2 protein and T2 DNA
C) a mixture of DNA and proteins of both phages.
D) T4 protein and T4 DNA
E) T4 protein and T2 DNA
A bacterium infected with an experimentally constructed bacteriophage will give new phages with the virus' DNA and the type of proteins that this DNA encodes.
A bacteriophage is a virus that attaches itself to a bacteria and uses it to replicate itself. Viruses have two main parts, a protein coat and their DNA inside it.
The experimentally constructed bacteriophage has one type of protein that makes the coat, the T2. This type of protein will allow the virus to attach and infect the bacteria. Once the virus attaches itself to the bacteria, it will introduce its DNA, T4 type, and use the bacteria elements to replicate it and create new phages.As a result, the new phages will have T4 DNA, and the proteins that the virus synthesizes will be the same type as the DNA.
In conclusion, The new phages produced would have D) T4 protein and T4 DNA.
