Petri dishes should always be stored inverted.

In biology, petri dishes are frequently used to produce microorganisms like bacteria, yeast, and mold. The organisms that grow on solid or semisolid surfaces are best suited for it. To reduce the chance of contamination from airborne spore particles landing on them and to avoid the buildup of water condensation that could disrupt or impair a culture, they are often covered and stored inverted.

Aside from that, incubating the media in the normal position could result in the media drying out, which would interfere with the ideal conditions for microbial growth and increase microbial count mistakes. Since the labels are put underneath the plates rather than on the lids, placing plates upside down also makes them easier to handle and recognize.

Science provides only a
melomori [17]

Science provides only a limited understanding of the supernatural, or other ways of knowing, such as art, philosophy, or religion is a true statement.

<h3>Why science provide limited information about supernatural?</h3>

Science provides only a limited understanding about supernatural, aesthetic, or other ways of knowing, such as art, philosophy, or religion because they are not proved by the science through experiments. These things are beyond from explaining them. Science can't explain the happening of supernatural phenomenon. Science does not create moral or ethical rules, laws, or judgements. Science deals with only things that can be observed or measured so that's why science is not understanding supernatural things.

So we can conclude that Science provides only a limited understanding of the supernatural, or other ways of knowing, such as art, philosophy, or religion is a true statement.

Why do the cells in all living things need energy? A. to fuel their chemical reactions B. to help them decompose C. to communica
Naddik [55]
The correct option is A.
A lot of biochemical reactions occur per minute inside living cells and these reactions have to be sustained because the survival of living cells depend on them. For these reactions to proceed, energy is needed. This energy is usually obtained from the food which a living organism consumed. The mitochondria, which is the power house of the cell, is the one which convert the energy to the ATP form, which is usable by the cells.

The influx of positive charges that makes the membrane potential more positive is?
Sunny_sXe [5.5K]

The influx of positive charges makes the membrane potential more positive and is known as depolarization.

<h3>What makes the membrane more positive charge ?</h3>

The membrane potential normally becomes more positive in response to neurotransmitters that open Na+ channels, more negatively in response to those that open K+ channels, and vice versa in response to neurotransmitters that inhibit these channels.

<h3>What does polarization mean?</h3>

The orientation dispersion of the electromagnetic waves that make up light beams is referred to as polarization. Unpolarized (uniformly mixed orientations), linearly polarized (fixed orientations), and circularly polarized are some of the different polarization states that light can take on (rotating field about the line of sight).

<h3>How membrane is affected by polarization and depolarization?</h3>

At a specific location on the neuron's membrane, hyperpolarization occurs when the membrane potential increases, and depolarization occurs when the membrane potential decreases (more positive).

Why don’t free amino acids have peptide bonds? What is a free amino acid exactly?
slega [8]

Explanation:

Free amino acid do not have a peptide bond , as the amino acid act as a monomer which multiplies and linked via peptide bond to generate protein chain .

A free amino acid have a carbonly group (- COOH ) and a -NH₂ group .

The formation of protein chain require at least two amino acids linked via peptide chain .

The role of peptide chain only comes in case of protein , because it acts as a linking species .

Hence , free amino acid does not have any peptide chain .
