Answer for brainiest :)
Answer:
D
Explanation:
Well, animal cells use simple sugars, like glucose. The simple sugars are the only ones small enough to pass through cell walls. We use ATP to access the energy in the sugars. Cells can either use a aerobic system (using oxygen) or an anaerobic system to metabolize sugars. Humans generally use the aerobic system although in some cases our cells are forced to use the anaerobic system.
The graph illustrates the activity level of three common digestive enzymes, across a range of pH values. Hydrochloric acid is used by the stomach to aid in digestion and causes the stomach to have an average pH of 1.5 to 3.5. Which enzyme is likely to be active in the acidic environment of the stomach?
Answer:
Digestion starts with the sight, thought, or smell of food. When the brain anticipates an incoming meal, the vagus nerve sends a message to the stomach causing the release of acetylcholine. The binding of acetylcholine to G cells in the stomach starts the secretion of gastrin and, in combination with acetylcholine and histamine, stimulates parietal cells in the gastric glands of the stomach body to start secreting hydrochloric acid (HCl).

B) Boiling and melting points are chemical properties.
C) A molecule of oxygen can have atoms of carbon in it.
D) Elements are substances made of only one type of atom.
Answer:
D) Elements are substances made of only one type of atom.
Explanation:
The only correct choice from the ones given is that "elements are substances made of only one type of atom".
Elements are distinct substances that cannot be split up into simpler substances. Such substances consists of only one kind of atom. There are over one hundred elements known to date.
Atomic number is the number of protons in an atom. Boiling points and melting points are physical properties of a substances. A molecule of oxygen is made up of only oxygen atoms that have been covalently bonded together.The heart is an example of which level of organization within an organism?

A. ATGAT
B. UAGCUA
C. TAGCTA
D. ATGGAT
Answer:
D
Explanation:
A substitution is where a base is substituted by another base
A. ATGAT - this is not a substitution, the C has been deleted
B. UAGCUA - this is not a substitution, but is the complementary mRNA sequence (you can tell because there are Us instead of Ts)
C. TAGCTA - this is not a substitution, but is the complementary DNA sequence
D. ATGGAT - this is a substitution, the C in the original sequence has been replaced (substituted) by a G.

(DNA) located?
A. Lysosomes
B. Nucleus
C. Ribosomes
D. Vacuole
Answer:
DNA is found in the nucleus. So B.
Explanation:
DNA is found in chromosomes and chromosomes are found in the nucleus because the nucleus is basically the DNA of a cell.
In the nucleus, cell structures are the Drosophila chromosomes (DNA) located. The correct option is B.
What is chromosomes?The thread-like components known as chromosomes are found in the nucleus of both animal and plant cells. Protein and a single molecule of deoxyribonucleic acid make up each chromosome (DNA).
DNA is passed down from parents to children and contains the precise instructions that give each kind of living thing its individuality.
a component that can be found in a cell's nucleus. Proteins and DNA are arranged into genes on a chromosome. There are typically 23 pairs of chromosomes in each cell.
One chromosome is made up of one protein and one DNA molecule. Different chromosome sizes can be packed together into a nucleus thanks to proteins called histones.
The DNA for the Drosophila chromosomes is found in the cell's nucleus.
Thus, the correct option is B.
