What is the definition for temperature inversion
Katyanochek1 [597]

A temperature inversion is a thin layer of the atmosphere where the normal decrease in temperature with height switches to the temperature increasing with height. An inversion acts like a lid, keeping normal convective overturning of the atmosphere from penetrating through the inversion.

1. Zygomycetes reproduce asexually through the haploid spores formed in , or sexually through diploid nuclei formed in .
g100num [7]

Answer:

  1. sporangia , zygospore
  2. Basidiomycota
  3. hyphae, mycellium
  4. lichen
  5. mycorrhiza
  6. Ascomycota

Explanation:

1. Zygomycetes reproduce asexually through the haploid spores formed in sporangia, or sexually through diploid nuclei formed in zygospore.

2. Basidiomycota are called club fungi because they produce club-shaped reproductive structures like toadstools.

3. The vegetative body of most fungi is called a hyphae, which consists of an interwoven mass of threadlike filaments called mycelium.

4.  A lichen is a symbiotic association between a fungus and a single-celled alga or cyanobacteria. The fungus protects the photosynthesizer from harsh conditions while consuming the extra nutrients it produces.

5. A mycorrhiza is a symbiotic association between a fungus and the roots of a plant. The fungus receives energy-rich sugar molecules produced by the plant while passing minerals and nutrients from the soil to the root.

6. Ascomycota, also known as sac fungi, include morels, yeasts, and the species that produces penicillin.

Fill in the blank Competition drives natural selection as individual members of a species compete with each other for limited na
maks197457 [2]

Answer:

1. Intraspecific

2. speciation

3. fossil record

4. The fossil record provides empirical evidence for evolution because it shows that species now aren't the same as species that existed in the past and that small changes happen over time to create new species.

5. A geographic variation in the fossil record occurs when two similar organisms occupy the same time span in two different places. These organisms hold the same purpose within the overall ecology.

6. A more detailed fossil record is preferable for supporting evolution because it allows for the instances of gradual change to be recorded and placed into broader speciation events.

7. Fossils provide a great many intermediaries that connect past species with their living descendants.

8. Intraspecific competition is competition that occurs within species. This is the competition that drives natural selection.
