1. Proteins
After RNA is formed, it is transported out of the nucleus and goes to the cytoplasm. From the cytoplasm, it goes into the ribosomes, where protein synthesis occurs. Together with transfer RNA (tRNA), mRNA will direct protein synthesis.
2. RNA is the direct result of DNA transcription.
Transcription is a process where DNA is transcribed into messenger RNA (mRNA). This carries all the information that will be needed to synthesize proteins.
3. Sugar and phosphates
The backbone of DNA, is made of sugar and phosphate. They form the structural framework of nucleic acids. They are arranged alternately, sugar-phosphate group-sugar and so on. The backbone refers to the sides of the DNA "ladder."
4. 500
In base pairing, guanine and cytosine pair up and adenine pairs up with thymine. Fore every adenine, there will be a thymine. If there are 500 adenine bases, there will be one for each one. So the answer is 500.
Answer:
Explanation:
a. True
b. False
The correct answer is A. True
Explanation:
Tissues are the basic structure of organs in both plants and animals. These are made of groups of specialized cells that have specific biological functions. For example, in animals muscles that support the movement are composed of muscle cells that had a specialized structure and function for this. This also applies to plants that are made of epidermal, vascular and ground tissues. According to this, it is true tissues are made of a grouping of cells as each tissue contains sets or groups of specific cells.
B. finding a comet
C. examining the structure of plant cells
D. building a garage
2. Which of the following procedures involves a physical change in one of the substances?
A. creating salt by reacting sodium metal and chlorine gas
B. allowing a nail to rust
C. building a model rocket propelled by mixing baking soda and vinegar
D. grinding chalk into a fine powde 3. You have three molecules of glucose (3C6H12O6). How many oxygen atoms do you have?
A. 1
B. 3
C. 6
D. 18
Question 1:
The right answer is A
Chemistry is a science of experimental nature that studies the composition of matter and its transformations.
Chemistry is thus interested in the elements that constitute matter (atoms, ions, etc.), in their properties and in the chemical bonds that can be created between them.
Question 2:
The right answer is A
Sodium chloride is an ionic chemical compound of the formula NaCl. It is more commonly called table salt or cooking salt, or simply salt in everyday language.
It is clear that it exists in the form of solid salts.
during his training, there was a physical change of sodium (metal) and chlorine (gas) into a salt.
Question 3:
This question is a little bit tricky
If we assume that the question is aimed at finding the total number of oxygen in all three molecules together, the answer is 18.
A glucose molecule is made up of 6 atoms of oxygens if we have three glucose molecules (assuming that they are bound), we multiply by 3 and this gives us 18 oxygen atoms.
Protozoans can move using pseudopodia, cilia, and flagella, but not by budding. The correct answer is d. budding.
You are absolutely correct, and I appreciate the clarification.
Protozoans employ various methods for movement, including pseudopodia, cilia, and flagella, with budding having no connection to their locomotion.
Pseudopodia are temporary extensions of the cell membrane utilized by organisms like Amoeba for both movement and prey capture.
Ciliates utilize numerous hair-like structures called cilia for propulsion, while flagella are whip-like structures used by certain protozoans like Euglena.
Importantly, budding is a distinct process related to asexual reproduction and not a means of protozoan locomotion.
Therefore, the correct answer is d. budding.
