the negative impact is that the air will get polluted and also that we will have less trees so less oxygen since they will be building more structures and factories and plenty of other stuff, that will lead to chopping up plenty of trees.

emmasim [6.3K]

Answer: 160 mm HgTherefore, the partial pressure of oxygen is: PO2 = (760 mm Hg) (0.21) = 160 mm Hg, while for carbon dioxide: PCO2 = (760 mm Hg) (0.0004) = 0.3 mm Hg.

A rooster with gray feathers is mated with a hen of the same phenotype. Among their offspring, 15 chicks are gray, 6 are black,
m_a_m_a [10]

Answer:

Alleles for feather colour exhibit incomplete dominance or co-dominance.

50% gray offspring + 50% black offspring

Explanation:

<em>It means that the alleles for feather colour in the hen exhibit incomplete dominance or co-dominance over one another.</em>

Assuming the allele for white colour is B, white colour will be b while the heterozygote Bb gives the gray phenotype.

Gray rooster + gray hen = 15 gray chicks, 6 black chicks and 8 white chicks.

15:6:8 is roughly 2:1:1 which is phenotypic ratio obtainable from crossing two heterozygous individuals as pointed out by Mendel.

Bb   x   Bb = 1BB, 2Bb, and 1bb

Crossing the gray rooster (Bb) with a black hen (bb):

Bb   x   bb = Bb, Bb, bb, and bb

          = 2Bb (gray):2bb (black)

50% of the offspring will be gray while the remaining 50% will be black.

To answer this question you must break apart the words given on the right.
“Eco” means life and production. So an ecologist would be someone who studies life and it’s processes. So the correct answer for the first blank would be C. Life Science.

A chemist is one who interacts with day to day elements and sciences that is tactile. So the most appropriate answer would be B. Physical science.

A geologist is someone who studies the earth. As the part of the word “geo,” meaning earth, suggests. So the correct answer here would be A. Earth science.

Finally, “Astro” means space .Astrology is the study of the stars and the sky, for example. So, D. Space science would be the best answer for an astronaut.

I hope all of these are helpful. :)

What might happen if a scientist inaccurately reported data from his or her experiment?
evablogger [386]

The inaccurate reporting of an experiment data will lead to the following consequences:

  1. Data will lack quantitative measures.
  2. Data will be less reliable due to inaccuracy.
  3. Data will not be reproducible by other scientists for validation of test results.
  4. Data will weaken the proposed testable hypothesis of the scientist.
  5. Data will break any trend that has been previously observed by the scientist.
