Which of the following is a possible long-term consequence of two organisms occupying the same niche?

1 answer:

4 0

Niche refers to the role of the microorganism or a living thing in an ecosystem. When two organisms occupying the same niche, the possible long-term consequence is A. local extinction. This is because the relationship is competition which can outlast the other. Eventually, when the environment is changed, the organisms adapt too which erases the original attributes.

How many paths through which charge can flow would be shown in a circuit diagram of a parallel circuit? more information is need

Tasya [4]

Answer: More than 1

Explanation:

A parallel circuit is defined by having more than one path through which current can flow. This is in contrast to a Series circuit where the current flows through just one path.

Even though there are multiple paths for the current to flow through, the current flowing through all the paths must add up to the total current that is being supplied from the source.

How do cigarettes and radiation cause cancer? View Available Hint(s) How do cigarettes and radiation cause cancer? by destroying

blagie [28]

Answer: B. by toxic chemicals (in smoke) or radiation that can damage the DNA in cells.

Explanation:

The carcinogens presents in cigerates covalently bind to DNA and form DNA adducts which results into miscoding (e.g., insertion of the wrong base) during replication of DNA and this genetic mutation causes uncontrolled cellular growth which causes cancer.

Ionising radiation including X-rays, radioactive particles, and gamma rays,can cause cancer by damaging DNA. high-energy radiation damages DNA and cause genetic mutation same as cigerates and causes cancer.

Both toxic chemicals (in smoke) or radiation damages DNA inthe cells which leads to cancer.

Hence, the correct option is B.
