The initial size of the cultured bacteria was around 2000 after an hour the bacteria count turned to 16000 with the value of n = 8000.

Given:

n = 1000 e^ (kt)

note when t = 0,

e^kt = e^0 = 1

1000*1 ar t = 0

Stepwise solution,

4000/1000 = 4 = e^(k*1)

or

e^k = 4

k = In 4 = 1.386

when n = 1000,

n = 1000 e^(!.386 t)

t = 1.5

n = 1000 e^(2.079)

n = 8000

Hence, the correct answer is (n=4000)

Which of the following contributes to antibiotic
MatroZZZ [7]

Taking multiple antibiotics at the same time contributes to antibiotic resistance. Thus, the correct option is B.

<h3>What is Antibiotic resistance?</h3>

Antibiotic resistance may be defined as a process or strategy of microorganisms that generate the capability to conquer the drugs developed to annihilate them.

Overprescription of multiple antibiotics increases the ability of bacteria or other microorganisms to survive in harsh little conditions. Still, slowly they evolve themselves and resist the situation of the high effect of antibiotic resistance drugs.

Therefore, it is well described above.

Which processes are involved in the chloroplast of a plant cell?
Ahat [919]

Answer:

Chloroplast absorbs sunlight and it is used to make feed for the plant together with water and carbon dioxide gas. Chloroplasts are used to generate the free energy stored in ATP and NADPH via a photosynthesis process.

Explanation:

The site of photosynthesis action is chloroplast within a plant cell consisting of two chlorophyll molecules (PS1 and PS2), which have been embedded in the thylakoid membranes. The chloroplast consists of two chlorophyll molecules (photosynthetic pigments responsible for the green color of chloroplast). Each chlorophyll molecule absorbs light, caused to depart the chlorophyll molecules. This absorbs two electrons from each phenotype. PS2 electrons pass through the transportation chain for electron carriers, a series of redox reactions that release the energy used to synthesize ATP via Photophosphorylation/Chemiosmose (as the H+ ions diffuse through the stalked particles ATP, which changes the shape and catalysts, the electrochemical gradient diffuses down through the stalky particle ATP synthase).

Then these electrons replace the electrons lost in PS1. PS2 electron is replaced by photolysis electron, which when light strikes chloroplast, splitting the water into oxygen gas, H+ ions, and electron enzymes in the thylakoid space are catalyzed. The PS1 electrons combine to create NADPH with H+ ions and NADP (reduced NADP). These are the light-dependent photosynthetic reactions in chloroplasts. In the light-independent reactions, the NADPH and ATP are created. A pile of thylakoids is known as granum.

The light-independent processes take happen in the stroma. This is the site of carbon fixation; CO2 reacts with RUBP to generate GP (glycerate-3-phosphate) which is catalyzed by the enzyme RUBISCO (the most abundant enzyme in the world) (the most abundant enzyme in the world). The NADPH and ATP from the light-dependent processes convert GP to GALP (glyceraldehyde 3-phosphate). Two out of every 12 GALP molecules produced are used to synthesize glucose that can be employed either in breathing or in cellulose-forming condensation polymerization to add extra strength to the planted cell wall. The other GALP molecules are returned to RUBP.

An instrument used for the visual examination of the ear is called a(n):
Alina [70]
The correct answer is tympanometer. A tympanometer is not used to measure hearing, but to rather measure the transmission of energy through the middle ear. In this way, tympanometry is an objective test of the function of the middle-ear. Tympanometry is used alongside other measures to asses hearing, such as pure tone audiometry.
