Answer:
Humans and marine organisms use sound finding depth of the ocean and objects.
Explanation:
Humans and marine organisms use sound for some underwater tasks such as finding depth of the ocean and objects. Human use sonar which is a device used to explore the ocean and animals use echolocation to find food and identify objects that comes in their way. Sonar is present in submarine uses sound waves to detect objects that comes in their way so both humans and marine organisms use sounds.
Answer:
Actually, cell division is the mechanism by which DNA is passed from one generation of cells to the next and ultimately, from parent organisms to their offspring. During meiosis, the cells needed for sexual reproduction divide to produce new cells called gametes.
Explanation:
The slopes show that sucrose gradient affects change in weight.
The slopes will be different because higher gradient concentration of sucrose will result in the higher amount of water moved. This means the higher sucrose gradient concentration, the more change in weight of the water.
Answer:
<em>The correct option is C) Plants</em>
Explanation:
Option A is false because the cell cannot be an animal cell. This is because an animal cell does not possess a cell wall.
Option B is false because the cell cannot be a bacterial cell. This is because a bacterial cell does not have a nucleus. Their genetic material is dispersed inside the cytoplasm.
Option C is correct because all the organelles, a cytoskeleton, mitochondrion, nucleus, cell wall, and ribosomes, are present inside the plant cells.
Now it is clear that genes are what carry our traits through generations and that genes are made of deoxyribonucleic acid (DNA). But genes themselves don't do the actual work. Rather, they serve as instruction books for making functional molecules such as ribonucleic acid (RNA) and proteins, which perform the chemical reactions in our bodies.Proteins do many other things, too. They provide the body's main building materials, forming the cell's architecture and structural components. But one thing proteins can't do is make copies of themselves. When a cell needs more proteins, it uses the manufacturing instructions coded in DNA.The DNA code of a gene—the sequence of its individual DNA building blocks, labeled A (adenine), T (thymine), C (cytosine) and G (guanine) and collectively called nucleotides— spells out the exact order of a protein's building blocks, amino acids.
Occasionally, there is a kind of typographical error in a gene's DNA sequence. This mistake— which can be a change, gap or duplication—is called a mutation.
