Homework Answers

Answer #1

Answer :

Cyanobacteria.

Discussion and explanation :

Bacteroides - Are obligate anaerobic heterotrophic bacteria.

Cyanobacteria (also referred as blue green algae): These prokaryotes (lacking nucleus) have thylakoids in their cytoplasm where photosynthesis takes place. As a result of photosynthesis these bacteria can prepare their own food (autotrophs) and also generate oxygen (oxygenic).

Algae are eukaryotes and contain nucleus.

Lactobacillus does fermentation to produce lactic acid without any need of light. It is prokaryote and lack nucleus.

Oomycota are fungus like filamentous microorganisms which are heterotrophs.

A phycologist is worried that a large proportion of the algae found in nearby water sources is cyanobacteria. He obtains a random sample of 50 alga from a local river and another random sample of size 75 from the local coastline. He finds that 22 of the river samples and 66 of the coastline samples are cyanobacteria. Let p1 and p2 represent the proportion of cyanobacteria in river and coastal populations, respectively. Calculate a 95% confidence interval for p1 -...

Indicate true (T) and false (F) statements below regarding the nucleus and nuclear protein transport. 1. The inner and outer nuclear membranes are continuous with each other, yet maintain distinct protein compositions. 2. A protein without a nuclear localization signal can be transported into the nucleus by binding to a protein with NLS. 3. The endoplasmic reticulum lumen is continuous with the nuclear interior. 4. Many proteins shuttle in and out of the nucleus.

The wavelengths of spectral lines depends to some extent on the mass of the nucleus. This occurs because the nucleus is not an infinitely heavy mass that remains stationary. In fact, in reality, both the nucleus and the electron orbit about their common center of mass. It can be shown that a system of this type is entirely equivalent to a single object with a mass μμ (called the Reduced Mass) that orbits about the location of the nucleus at...
