Answer:
damp and cool conditions will attract snails . but unfortunately most gardens require
a moist environment.
DNAase is an enzyme that catalyzes the hydrolysis of the covalent bonds that join nucleotides together. What would first happen to DNA molecules treated with DNAase?
A) The purines would be separated from the deoxyribose sugars.
B) The pyrimidines would be separated from the deoxyribose sugars.
C) All bases would be separated from the deoxyribose sugars.
D) The two strands of the double helix would separate.
E) The phosphodiester bonds between deoxyribose sugars would be broken.
Answer:
E) The phosphodiester bonds between deoxyribose sugars would be broken.
Explanation:
The purines and pyrimidines of two DNA strands of a DNA duplex are held together by hydrogen bonds. Hydrogen bonds are not covalent bonds. The enzyme DNAase targets the phosphodiester bonds. These are the covalent bonds that join two deoxyribonucleotides of a DNA strand together. therefore, when a DNA is subjected to digestion with DNAase enzyme, the phosphodiester bonds will be broken that hold the pentose sugars of two nucleotides by a phosphate group.
1. a sugar, a phosphate, and a base (such as Adenine.)
2. Deoxyribose
3. TCGAGTC, A pairs with T and G pairs with C
4. 55 adenines, 100-45=55
Answer:
The body uses sugars from carbohydrates which supply the brain with glucose as the brain uses it as a "fuel source".
<h2>Why is glucose so important for the brain?</h2>
Quick answer: It takes a lot of energy to receive, interpret, and send signals via your neurons. Glucose is the simples sugar that can be used to make energy.
Cells require energy to carry out their typical everyday tasks. The simplest sugar that our cells can utilize for energy is glucose. Since your neurons are specialized cells, many additional cells are also present to support or protect them. All of the senses you can experience utilizing incoming neurons (from the body to the brain) are transmitted to and interpreted by the brain, including touch, pain, vibration, temperature, smell, sight, hearing, taste, and others. Signal reception and interpretation need energy. Additionally, your brain instructs your body to "do" things, which uses energy. Additionally, you spend a significant portion of your waking hours "thinking," which consumes energy. This explains why 20% of the glucose in your body is used by our teeny, tiny, little brains.

Cuz they combine during fertilization and since 2 halves = 1 whole, u get gametes w a full number of chromosomes
