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.

A solid colored, short-haired female rabbit (ssLL) is mated to a spotted, long-haired
OlgaM077 [116]

Answer:

Spotted with long hair⇒ 12

Solid colored and short hair⇒ 12

Explanation:

Both genotypes are homozygote type. So, they will produce only one type of gamete from each. that are sL and Sl.

The genotype of F1 offspring will SsLl ( spotted short hair, heterozygote)

when F1 offsprings are interbreeded four types of phenotype are produced.

they are

  1. spotted short haired ⇒ \frac{36}{64} (dominant type)
  2. spotted long hair ⇒ \frac{12}{64}
  3. solid colored short hair⇒ \frac{12}{64}
  4. solid colored long hair⇒ \frac{4}{64}

What are the body’s three defenses? How do they differ from each other.
Artemon [7]

Answer:

- Physical and chemical barriers

- non-specific innate responses

- specific adaptive responses

<u>The differences are...</u>

The first barrier is the physical and chemical barrier. It is the first line of defense when in contact with outside sources, this can be through the skin, earwax, nose-hair, etc.

The second barrier, the non-specific innate response, is after these outside sources have somehow managed to pass through the first barrier. They come into contact with cells and enzymes that help to defeat them.

The third barrier, the specific adaptive response, is the body's way of dealing with pathogens that the body has encountered before. (B cells activate)
