Answer:
50%
Explanation:
This question involves a single gene with two alleles W and w in puppies. According to the question, the genotype of the parent organisms are Ww. In a cross between the two parents i.e. Ww × Ww, the following gametes will be produced by each parent: W and w.
Using these gametes in a punnet square (see attached image), the following genotype of offsprings will be produced: WW, Ww, Ww, ww. Hence, based on this question, the percentage of puppies that would have the same genotype as the parents, Ww are 1/2 × 100% = 50%.
Answer:
b. making an observation and asking a question
Explanation:
In scientific method there need to be a situation to be study. In this description, the scientist first observed that in a certain region there is some kind of trees and the other variable is the great amount of deer.
After making different observations, and some research of other areas similar to the one that is study, she is asking what is the relation among the animals and the trees.
The next step will be to formulate a hypothesis using all the data and the two variables that she observed.
Maria and craters are explained below:
<u>Explanation:
</u>
- The Moon is divided into light area lunar highlands and a dark area called Lunar Maria.
- Lunar Maria is large, dark, basaltic plains formed on earth's moon formed by ancient volcanic eruptions.
- Craters are formed when an impacting object falls and hits the moon's surface with greater speed and also formed as a result of the outward explosion of rocks.
- Craters are often caused by asteroids and meteorites with the lunar surface.
- Unlike earth-moon does not have an atmosphere to protect itself from impacting bodies. This is the reason for more number of craters formed on earth.
Any three characteristics of bacteria area
- lack of membrane-bound organelles
- unicellular
- small (usually microscopic) size.
