What would happen to the enzyme phosphatase if we decrease the PH to 3

Which of the following is a concern if you forgot to resuspend (mix) culture solutions when performing serial dilution?

Illusion [34]

Answer:

B) CFU/mL calculations would not be accurate

Explanation:

In microbiology CFU is the acronym for Colony Forming Unit, which indicates the number of bacteria or fungi capable of multiplying under suitable conditions. In this case, CFU/mL indicates how much bacterial or fungal cells, susceptible to reproduction, exist within 1 mL of a culture solution.

When this solution is used, to make a dilution or other laboratory activity, it is important that it be resuspended, that is, mixed, as the bacteria or fungus cells can accumulate in the bottom or surface of the substance, changing the value of CFU/mL and causing inaccurate dilutions if used. When resuspended, the substance presents the appropriate value of CFU/mL, ensuring that the dilution is accurate and effective.

Which laboratory proven medication is used to control HIV , write the name of the medication in full .?

Elina [12.6K]

HIV medications can help lower your viral load, fight infections, and improve your quality of life. But even if you take them, you can still give HIV to others. They're not a cure for HIV.The goals for these medicines are to:Control the growth of the virusImprove how well your immune system worksSlow or stop symptomsCause as few side effects as possibleThe FDA has approved more than two dozen antiretroviral drugs to treat HIV infection. They're often broken into six groups because they work in different ways. Doctors recommend taking a combination or "cocktail" of at least two of them. This is called antiretroviral therapy, or ART.Your doctor will let you know specifically how you should take your medications. You need to follow the directions exactly, and you shouldn't miss even one dose. Or you could develop drug-resistant strains of HIV, and your medication may stop working.Some other medicines and supplements don't mix well with HIV drugs, so make sure you tell your doctor about everything you're taking.Nucleoside/Nucleotide Reverse Transcriptase Inhibitors (NRTIs)NRTIs force the HIV virus to use faulty versions of building blocks so infected cells can't make more HIV.Abacavir, or ABC (Ziagen)Didanosine, or ddl (Videx)Emtricitabine, or FTC (Emtriva)Lamivudine, or 3TC (Epivir)Stavudine, or d4T (Zerit)Tenofovir, or TDF (Viread)Zidovudine, or AZT or ZDV (Retrovir)Non-nucleoside Reverse Transcriptase Inhibitors (NNRTIs)These are also called "non-nukes." NNRTIs bind to a specific protein so the HIV virus can't make copies of itself, similar to jamming a zipper.Delavirdine (Rescriptor)Efavirenz (Sustiva)Etravirine (Intelence)Nevirapine (Viramune)Rilpivirine (Edurant)Protease Inhibitors (PIs)These drugs block a protein that infected cells need to put together new copies of the HIV virus.

(a) Name two processes that remove carbon from the atmosphere: _____ (b) Name two processes that add carbon to the atmosphere: _

Vikentia [17]

The two processes that remove carbon dioxide from the atmosphere are photosynthesis and absorption. Respiration and volcanism, or the eruption of molten rock, are the two processes that provide carbon to the atmosphere.

carbon is removed from the atmosphere through photosynthesis and replaced with O2. O2 is removed from the atmosphere during respiration and replaced with carbon . These processes, however, are not in equilibrium. Not every organic substance oxidizes. Photosynthesis and metabolism are the two fundamental processes that take place during the natural carbon cycle. Plants consume carbon dioxide during photosynthesis to create oxygen, and they also make carbon dioxide during metabolism.

Were the gases used to create Earth's primitive Oceans and what were the contents of the liquid pool after the experiment ran fo

Oksana_A [137]

The gases present at the origin of the earth were believed to be nitrogen (N2), Carbon dioxide (CO2), water vapor (H20), and maybe some carbon monoxide (CO).

<h3>Origin of the earth</h3>

The earth is believed to have originated in what scientists have referred to as the big bang in which several gases were formed.

The gases present at the origin of the earth were believed to be nitrogen (N2), Carbon dioxide (CO2), water vapor (H20), and maybe some carbon monoxide (CO). The gases aggregated to form amino acids hence the origin of the initial life forms.

Identify the isolation mechanisms described using the drop-down menus. Differences in courtship or other behaviors prevent matin

lana [24]

Answer:

First, let's add the missing piece of information

Identify the isolation mechanisms by labeling either Geographical, Behavioral, Temporal, or Anatomical from the drop-down menu

The correctly identified mechanism is

1. Behavioral

2. Geographical

3. Temporal

4. Antomical

Explanation:

Differences in courtship or other behaviors prevent mating.- our answer is Behavioral

(Behavior isolation is the term used to describe reproductive isolation as a result of variations in courtship behaviours between the members of the same species occupying the same region).

Species can no longer interact because they are separated by physical boundaries.- it is Geographical

(Geographic isolation is seen in situations where the two populations of the same species get isolated by a geographical barrier such as mountain, island or river. This results in an inability to breed between the two populations as they become distinct new species).

Species do not interbreed because they breed at different times. this is definately Temporal.

(Temporal isolation is a form of reproductive isolation due to mating at separate times and seasons among two populations of the same species).

Species cannot physically mate due to genitalia or gametes being incompatible. And the correct answer is Antomical.

(Anatomical isolation

It is observed in situations when two populations of the same or distinct species cannot interbreed due to physical features such as genitalia and gametes formed in the organisms that make them uniquely separated).

Yes! this is the right answer. I just solved this question and its CORRECT.
