Answer:
A gene is a stretch of DNA or RNA that determines a certain trait. Genes mutate and can take two or more alternative forms; an allele is one of these forms of a gene. For example, the gene for eye color has several variations (alleles) such as an allele for blue eye color or an allele for brown eyes.

Answer:
True breeding
Explanation:
True breeding is a breeding in which parents produce the offspring which carry same phenotype.
The parents in true breeding are homozygous for every trait.
<u>True breeding occurs in the plants when the plants produce offspring of same variety only when self pollination takes place. </u>
<u>For example, if a plant has purple flowers will produce only seeds which will grow into plants which have purple flowers.</u>
Answer:
Light bounces off surfaces property most likely believed by Janssen about light during the time of his invention
Explanation:
Zacharias Janssen is ascribed as a man to discover the compound microscope. Its purpose is to amplify diminutive things so characters can analyze them. There is a mirror attached under the microscope and when light bounces off the mirror it reaches through and nearby the specimen being viewed.
Some elements do not receive light. When a light wave is reflected off a facade, it proceeds back off at an angle similar that the wave beats the surface. Using these more innovative concepts about light enacted scientists to compose new inventions.
Answer:
Explanation:
We are asked to find the energy given mass, specific heat, and change in temperature. Therefore, we must use this formula;
The mass is 15 grams and the specific heat is 0.129 J/(g×°C). Let's calculate the change in temperature.
- ΔT= final temperature - initial temperature
- ΔT= 85 °C- 22°C = 63°C
Now we know all the values:
Substitue the values into the formula.
Multiply the first numbers together. The grams will cancel.
Multiply again, this time the degrees Celsius cancels.
<u>121.905 Joules</u> are required.
