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.

What is the table of science?
oee [108]

I think you are refering to the periodic table. The periodic table is important because it is organized to provide a great deal of information about elements and how they relate to one another in one easy-to-use reference. The table can be used to predict the properties of elements, even those that have not yet been discovered.

Robins typically lay four eggs. Four eggs allow the offspring to be well fed, whereas larger clutches may result in malnourished
Amanda [17]

Answer:

Stabilizing selection

Explanation:

The process of natural selection selects a species in one of the three ways: stabilizing selection, directional selection and disruptive selection.

During the process of stabilizing selection, nature does not favour the extreme phenotypes of the population but the intermediate phenotype with the maximum number of population.

In the given question, the Robin laid four eggs, neither more than four nor less than four which could have more disadvantages than the advantages.  Since the intermediate number of eggs is favoured by nature therefore the stabilizing pattern is observed.

Thus, Stabilizing selection is correct.
