Answer:

By the observation, the rod shape violet-colored bacteria could be a Gram-positive bacillus which is <em>Lactobacillus spp</em>.  in curd.

Explanation:

Gram-stain is a staining method to isolate and study the Gram-positive or Gram-negative bacteria with the help of the crystal violet dye. Crystal violet dye stains both Gram-positive and Gram-negative bacteria in purple stain. After decolorization, Gram-negative bacteria appears to be pink in color, however,Gram-positive bacteria remain purple.

According to bacteria structure, they term as bacillus (rod), strepto (clusters or threads) or Diplo (in pairs).

Thus, according to the observation, the rod shape violet colored bacteria are Gram-positive bacillus which is <em>Lactobacillus spp</em>. in curd.

How is a raft different from a typical ecosystem when considering carrying capacity?
harkovskaia [24]

Answer:

Explanation:

A raft is a flat-bottom structure made of planks or barrels that has the capacity to float on water. While an ecosystem is a community of living organisms (biotic) interacting with there non-living (abiotic) environment as an ecological unit.

A raft by design cannot withstand much load because of it's size or can only accommodate  only one type of organism at a time but an ecosystem generally accommodates a community (different organisms), hence the carrying capacity of an ecosystem is way larger than that of a raft and indeed a raft can be part of an ecosystem at some point

What is represented by<br> region on the sound<br> wave
elena-s [515]

Answer:

Compressions and Rarefactions

<em>A vibrating tuning fork is capable of creating such a longitudinal wave. As the tines of the fork vibrate back and forth, they push on neighboring air particles. The forward motion of a tine pushes air molecules horizontally to the right and the backward retraction of the tine creates a low-pressure area allowing the air particles to move back to the left.</em>

Explanation:

These regions are known as compressions and rarefactions respectively. The compressions are regions of high air presure while the rarefactions are regions of low air pressure.

<em>Sound waves can also be shown in a standard x vs y graph, as shown here. This allows us to visualise and work with waves from a mathematical point of view. The resulting curves are known as the "waveform" (i.e. the form of the wave.) The wave shown here represents a constant tone at a set frequency.</em>

how are mutations continually being generated in a population (what are some of the causes of mutatuions?) explain
vampirchik [111]
Some causes could be the mother smoking, drinking, doing drugs etc. Or even simply her body doesn’t fully accept the baby growing inside her so it acts out against it. Sounds strange but it happens. Also if the mother is sick with Zika or another virus, it can harm the baby’s growth.
