Answer:

Traits acquired during an organism's lifetime cannot be passed

Explanation:

<em>The law of use and disuse of organs as postulated by Jean Lamarck was wrong due to the fact that environmentally acquired characters cannot be passed to offspring.</em>

Changes to organisms that are not the level of the gene cannot be passed to the offspring. <u>For example, a wrestler that got big muscles due to constant work out cannot pass big muscles to his offspring. The offspring will need to work out in order to have big muscles. This is because big muscles in the wrestler is environmentally acquired.</u>

Only changes that happen to the genome of an organism (mutation) can be passed to offspring.

18. Which types of mutations, positive, negative or neutral, are most likely to be seen in offspring
Temka [501]
<h2>The following scenarios state whether the mutation is likely to be passed on to the offspring of the organism or not: </h2><h2> </h2>
  • a. A single bacteria cell contains a positive mutation in its DNA - The mutation is likely to pass as it is a unicellular organism with the cell itself containing the positive mutation.

  • b. A skin cell on a cat contains a positive mutation in its DNA - The mutation is not likely to pass as it is the skin cell.

  • C. A sperm cell in a whale contains a positive mutation in its DNA - The mutation is likely to pass as it is in the sperm.

Which tool is most likely to be used to produce a clear image of very tiny structures inside a cell? a light microscope b electr
FrozenT [24]

<em>Electron microscope </em><em>is most likely to be used to produce a clear image of very tiny structures inside a cell</em>

Answer: <em>B. Electron microscope</em>

Explanation:

The electron microscope is a kind of magnifying instrument that utilises electrons to make a picture of the objective. It has a lot higher amplification or settling power than a typical light microscope. The tiny structures inside the cell are easily visible under the electron microscope.

The electron microscope can be scanning electron microscope or tunnelling electron microscope. Both the type of electron microscopes differ in function but uses electron as its source of illumination.

Use evidence from the Grants’ research to explain how natural selection leads to evolution. (10 points)
Fiesta28 [93]

Answer:

The correct answer is - Grant's research on finches on the Galapagos islands.

Explanation:

Grant's research was made on medium-sized finches on the Galapagos islands showed evolutionary processes in real-time. He showed that due to the drought there is a decrease in the number of small and soft seeds that were finches major food source.

It is known that there are different beak sizes in this finch species, the finches with larger beaks could feed on tough and large seeds and survive in such case of the drought-induced decrease in food availability. Due to this natural selection and adaption the number of larger beaks in finches is increased over the real time.

In order for pest to feel comfortable and survive well in the food facility they need access to
stich3 [128]

The right answer is Nutrients and water.

All unicellular organisms such as bacteria and fungi need water, a source of energy, a source of carbon, a source of nitrogen and mineral elements. These basic needs are sufficient to allow the nutrition of bacteria qualified as prototrophs. Some bacteria called auxotrophs require, in addition to basic needs, the presence of growth factors.
