can sinus spread through sexual contact?
plz say the correct answer those who dont know dont reply ok
thank u!
Answer:
No, sinus can not spread through sexual contact but Individual may take precaution.
Explanation:
You can't spread them to other personalities. Bacterial sinus diseases are less constant. Bacteria generate less than 2 percent of sinus diseases. It's suggested that people with sinus infections avoid straight contact (for example, through kissing) with those who are more likely to a contaminant, for example, children, the aged, and those who have exhausted immune systems to decrease the possibility of transporting bacteria, fungi, and viruses to other people.
If mongoose were removed from this simple food chain, what effect would that have on the snakes?
Answer: they would be dead
Explanation:
Answer:
Mongoose are opportunistic feeders that will eat birds, small mammals, reptiles, insects, fruits, and plants.
Explanation:
so, if they are removed, there would be a population crisis. there would be too many snakes to control because the mongoose are one of the animals groups that eat snakes. the snake population increases. less mongoose= more snakes

A group of three nitrogen bases in an rna molecule codes for one_____.
1. Specific protein
2. Ribosome
3. Gene
4. Amino acid
Answer:
The correct answer is - 4. Amino acid
Explanation:
A group of three nitrogen bases in an RNA molecule codes known as triplet code that are copied by the DNA sequence by the process of the transcription and this RNA molecule is known as mRNA molecule. Each mRNA molecule has complementary sequences of nitrogenous bases of DNA sequence.
These nitrogenous base present in the mRNA molecule makes a set of three bases to code for a particular amino acid, for instance, AUG codes for methionine amino acid.

What is the function of the macromolecule subunit below?
Answer:
C. Stores genetic information
Explanation:
The macromolecule shown in the image represents nucleotide as it consist of one phosphate, one pentose sugar, and one nitrogenous Base.
The nucleotides are found in Nucleic acids (DNA and RNA) that functions to store genetic information and transfer it to next generation. They are found in all living things on Earth.
Hence, the correct option is "C. Stores genetic information".
Answer:
c. stores genetic info

Which set of items listed can be arranged to transform chemical energy into mechanical energy? A. motor, fan blades turning, wire
B. magnet, wire, fan blades turning
C. battery, wire, fan blades turning
D. battery, magnet, heat
Answer:
C
Explanation:
your welcome
The set of items which can transform chemical energy into mechanical energy is the battery, wire, fan blades turning. Thus, the correct option is C.
What is energy conversion?
Chemical energy can be converted into mechanical energy by the arrangement of batteries, wire, and fan blades turning. The chemical energy from the movement of ions in the wire causes the movement of fan blades and this turning is a form of mechanical energy.
In a combustion engine, chemical energy is first converted to heat energy that causes expansion of a fluid which results into motion. In contrast, the motor proteins are the molecules which can convert the chemical energy present in the molecules released from adenosine triphosphate (ATP) hydrolysis directly into useful mechanical work.
Therefore, the correct option is C.

Which physical evidence supports the evolution of earth due to chemical weathering?
A. Hammer shape of Bryce Canyon rocks.
B.Red color of Bryce Canyon rocks.
C.Streaks of the face of Wave Rock.
D. Concave shape of Wave Rock
Explanation:
how much is that I was in a while and it will get a new for me too 60th anniversary to the hospital for my family is so good and I don't think you should go for the next time we got home
Answer:
The correct answer is - Concave shape of Wave Rock.
The concave shape of Wave Rock is a nice physical evidence of deposition in the Earth's evolution. It is a land structure dated to 2.7 billion years old, and it is the basis around which the Australian continent formed. The Wave Rock structure is created by weathering of the surrounding area, and this is exactly what proves the deposition part, because Wave Rock was bellow the ground, and that was due to the deposition of the material around it over time, but since it is made out of much tougher material from its surroundings, the weathering lowered the surrounding terrain, while the bedrock remained to witness for the past.
