Sample could get contaminated with an acid. because vinegar contains acetic acid.Acetic acid is the second simplest carboxylic acid (after formic acid) and consists of two small functional groups, an acetyl group (sometimes symbolized as Ac) and a hydroxyl group (AcOH); it can also be viewed as a methyl group and a carboxyl group linked. It is an important chemical reagent and industrial chemical
<em>2:4 homozygous recessive; 50% heterozygous.</em>
Explanation:
I will be using the letter B to represent dominant alleles and b to represent recessive alleles.
If a canary is heterozygous, that means that it will have (Bb). Hetero, means different, so it will <em>never </em>be both (BB) or (bb).
If the other canary is homozygous recessive, it will be (bb). Homo, means the same, so it will <em>never </em>be (Bb). If the canary were homozygous dominant, it would be (BB).
I made a Punnett square to figure out the ratio and the percentage that is being asked in the question. As you can see, if you bring down the alleles from both of the parents accordingly, you will get...
<u>2:4</u> of the offspring will be potentially <u>homozygous recessive</u>.
<u>50%</u> of the offspring will be <u>heterozygous</u>.
Answer:
The two hydrogen atoms and one oxygen atom within water molecules (H2O) form polar covalent bonds. ... As a result of water's polarity, each water molecule attracts other water molecules because of the opposite charges between them, forming hydrogen bonds.
Explanation:
Answer:
The sample size is too small
Explanation:
<em>The problem most likely identified by Roberto would that the sample size is too small.</em>
A small sample size during an experimental study would decrease the statistical power of the data from such an experiment and increase the likelihood of making an error - type II error. Type II error occurs when the null hypothesis is confirmed instead of being rejected and this often occurs due to small sample sizes.
<u>The student used just a tomato plant for each study group. This represents a small sample size. Hence, the main reason for criticizing the experiment performed would be due to the small sample size.</u>
Movement of surface currents
Explanation:
- Remote sensing is used to gather data regarding Land use-mapping, weather forecasting, environmental study, and resource exploration.
- In the case of ocean currents, only satellite remote sensors can determine ocean currents synoptically over coastal regions.
- SAR(Synthetic Aperture Radar) is also used to determine the ocean currents.
- The flow patterns of ocean currents are drafted with satellite infrared scanners.
- Usually, many oceanographers use Radio antenna and high-frequency "Radio detecting and Ranging" for measuring surface ocean currents.
