Answer:

B

Explanation:

Measurement of Water in the Air

The specific humidity of air is a measure of how much water is in the air. Warmer air can hold more water than colder air. When the air reaches its capacity, it is saturated. This capacity doubles for about every 11°C rise in temperature.

Which of these is a way climate change positively affects organisms?
ArbitrLikvidat [17]

<u>Answer:</u>

<em>Climate change positively affects organisms by </em><em><u>providing them new habitat. </u></em>

<u>Explanation:</u>

Climate change induces <em>changes in various parameters of an ecosystem </em>like temperature, precipitation, soil properties etc. habitats may undergo changes that make it unsuitable for native organisms to live in.

But this <em>new conditions</em> may be favourable for some other kind of organisms to thrive and flourish.

<em>For example, </em>when temperature of a lake increases due to climate change warm water aquatic organisms find a new habitat in the lake. But this threatens the life of <em>native cold water organisms of the lake. </em>

Thus climate change doesn’t bring any benefits to living world without harming one or the other <em>group of organisms. </em>

Which of the following gases was not prevalent in Earth’s atmosphere during the Hadean Eon?
gavmur [86]

<span>The gas which was not prevalent in Earth’s atmosphere during the Hadean Eon is CO2. If you are going to see the composition of the Earth's atmosphere, Carbon Dioxide has the least percentage.
</span>This is because after the hydrogen and helium had escaped, Earth's Hadean atmosphere was left with methane, ammonia, water vapor, and small percentages of nitrogen and carbon dioxide. 
See attached file for further information about the Earth's atmosphere during the Haedan Period.

Which of the following pairs of protists and their ecological roles are correctly matched?
melisa1 [442]

Answer:

The correct pair is A: "apicomplexans—parasites of animals"

Explanation:

  • Euglenophyta is a group of unicellular, eukaryotic organisms. They are small, free-living forms, or parasites that present different feeding mechanisms and behaviors, such as heterotrophy, autotrophy, or mixotrophy.
  • Dinoflagellates are unicellular, flagellated, free-living protists that might form colonies. Most of them are autotrophic organisms but some of them are heterotrophic, or mixotrophic. In these last cases, dinoflagellates can feed on other dinoflagellates, protozoans, or diatoms. They can also be parasites.
  • Entamoebas are endoparasitic organisms with no mitochondria as an adaptation of living in environments with low oxygen concentration.
  • Apicomplexa is a unicellular, protist group. They have medical and economic importance as they are<u> animals</u> and human parasites. They have an apical complex that helps them to fixate to the host cell and release a substance that provokes an invagination in the host membrane. This invagination allows the parasite to get into the host cell.
