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.

Fruit flies have a diploid number of 8 and have a diploid number of 32. In which case will crossing over have greater impact on
Dovator [93]

Answer:

Diploid cells are like daughter cells coming from a mother cell called a haploid cell. So the more daughter cells are born, the greater the chance of getting hybrids and creating more diversity on the genetic races existing. In this case, the answer would have to be honeybees.

A scientist observes that, when the pH of the environment surrounding an enzyme is changed, the rate the enzyme catalyzes a reac
vredina [299]

Answer:

A- A pH change can cause the enzyme to change its shape

Explanation:

A rise or fall in the pH of the medium from the optimum of pH 7 usually affect  the  enzymes' active sites  of  and therefore the  shape and  the  rate of enzyme activity.

Assuming  the pH is too low, the enzyme medium becomes acidic;Acidosis. The high Hydrogen ions concentration  interacts with the R-groups of the amino acids moiety of the enzymes, this interaction affects the ionization of the  R-groups, disrupting the ionic bonding holding these R-groups in shape.

This results in loss of the 3-Dimensional shape arrangements of the protein molecule  and therefore of the active sites. Since active sites of  enzymes  determines the specificity of the <u>enzymes substrate- complex </u> to give <u>enzyme-product complex,</u> the catalytic activity of the enzymes decreases, <u>the rate of  reaction decreases,and products formation stops, and the reaction also stops.</u>

The same is applicable to extremely high pH=Alkalosis.

However, the effective buffer system of the body prevents this scenarios from happening in real sense in the body. Through mopping by the  haemoglobin, excretion by the kidney, etc
