Answer:
B: Alveoli.
Explanation:
ANSWER:
The correct option is B: Alveoli. Gas exchange of "carbon dioxide and oxygen" takes place in the "alveoli" of the lungs.
EXPLANATION:
Alveoli are present in the alveolar sacs located at the end of respiratory bronchioles. Alveoli have thin walls and look like bubbles in the sacs. These also are in "direct contact" with the blood capillaries. This contact ensures that "oxygen" is released into the blood capillaries by the alveoli directly.What achievement does king think Nobel prize committee is recognizing him for
his efforts to fight oppression without violence
Answer:
The correct answer is option D. his efforts to fight oppression without violence .
Explanation:
Nobel prize is the annual awards that are presented to the people done extraordinary performance in different fields such as peace, physics, chemistry and other fields.
All three options except option (d) his efforts to fight oppression without violence, are not achievements but a reaction or feeling. He can get nobel prize for peace for his efforts to fight oppression without violence .
Thus, the correct answer is option D. his efforts to fight oppression without violence .
What is a photon?
A. Part of a ribosome
B. A light particle
C. A carbon dioxide molecule
D. Part of a chloroplast
Answer: B.A light particle
Answer:
B. A light particle
Explanation:
The definition of a photon from the list of options is (b) a light particle
Explaining the definition of the term photon?By definition, a photon is a fundamental particle of light and electromagnetic radiation.
It is the basic unit that carries energy in the form of electromagnetic waves. Photons have both particle-like and wave-like properties.
They do not have mass but have momentum and travel at the speed of light in a vacuum.
Using the above as a guide, we have the following:

A plant with a life cycle that lasts only a year is called a(n) ____ plant. annual perennial yearly monocotyledon
Answer:
Annual plant
Explanation:
An annual plant is called as such because it takes one year for it to go from seed, growth, seed production, then death. All parts of the annual plant dies after one year, including the roots, the stems, and the leaves. The main purpose of the annual plants is to produce as much seeds that will survive. Unlike the perennial plants, they do not regrow seasonally.
draw the structure of DNA nucleotide with adenine as nitrogenous base
Answer:
A nucleotide is made up of one sugar molecule, one phosphate molecule and one of the four bases. Here is the structural formula for the four nucleotides of DNA. Note that the purine bases (adenine and guanine) have a double ring structure while the pyrimidine bases (thymine and cytosine) have only a single ring.
Explanation:
A nucleotide is made up of one sugar molecule, one phosphate molecule and one of the four bases. Here is the structural formula for the four nucleotides of DNA. Note that the purine bases (adenine and guanine) have a double ring structure while the pyrimidine bases (thymine and cytosine) have only a single ring.
A DNA nucleotide with adenine consists of a phosphate group, deoxyribose sugar, and adenine base connected to the deoxyribose.
A DNA nucleotide with adenine as the nitrogenous base consists of three main components: a phosphate group, a deoxyribose sugar, and adenine as the nitrogenous base.
Firstly, there is a phosphate group which is a phosphorus atom bound to four oxygen atoms.
This group provides the backbone's negative charge to the DNA molecule and contributes to its structural stability.
Secondly, we have the deoxyribose sugar, a five-carbon sugar. It is a pentose sugar, meaning it has five carbon atoms. The carbons are labeled from 1' to 5' (prime).
The phosphate group is attached to the 5' carbon of one deoxyribose sugar and the 3' carbon of the preceding deoxyribose sugar, forming the sugar-phosphate backbone of the DNA strand.
Lastly, adenine is one of the four nitrogenous bases in DNA and is classified as a purine. It is attached to the 1' carbon of the deoxyribose sugar.
Adenine forms hydrogen bonds with thymine (T) in complementary base pairing in a DNA molecule. The nitrogenous base adenine has a specific structure, including a double ring.
In summary, the DNA nucleotide with adenine includes a phosphate group forming the backbone, a deoxyribose sugar providing the structure, and adenine as the nitrogenous base attached to the deoxyribose sugar at the 1' carbon.
This structure is fundamental to the building blocks of the DNA molecule, allowing for the storage and transmission of genetic information.

Which of the following should be used to make a precise measurement of liquid volume
A graduated cylinder is the correct tool for making precise measurements of liquid volume, with marked scales for accuracy and the ability to measure at different increments.
To make a precise measurement of liquid volume, the appropriate tool to use is a graduated cylinder. Graduated cylinders are specifically designed to measure liquid volumes with a high degree of accuracy. They are marked with a graduated scale that allows users to read the volume of liquid inside the cylinder. Option D
These marks indicate specific volumes, which can vary in measurement units such as milliliters (mL) or centiliters (cL). For instance, if you're measuring a small volume of liquid, a 100-mL graduated cylinder can measure with an accuracy of "+/-1 mL", allowing for quite precise measurements. When using a graduated cylinder, it's important to measure at eye level and use the lowest point of the liquid's meniscus to obtain an accurate reading.
