Endocytosis brings large particles ​
Liono4ka [1.6K]

Explanation:

During endocytosis large cells, particles, and cell fragments moved across the plasma membrane through a process of invagination; part of the external cell membrane folds into itself and creates a small pocket that surrounds the target molecule, this breaks off from the membrane to form an intracellular vesicle.

Specific endocytosis processes, such as phagocytosis, pinocytosis, and endocytosis are regulated by receptors-they take in cells, fluids, and specific compounds respectively. During phagocytosis, cells absorb large particles in cell compartments called phagosomes, after which specifically enzyme-containing lysosomes break them down.

Using the s-p timing method, epicenters can be located using seismograms from a minimum of ______ recording stations.
KATRIN_1 [288]

The SP timing method is a technique, which is useful for finding the epicenter of the earthquake. The Seismograph at a particular station shows the S and the P waves. The difference between the S and the P waves can be used to determine the distance, which waves have travelled in order to reach the seismic station.

The distance obtained is the distance of the epicenter from that seismic station, in order to determine the epicenter the circle is drawn in the map keeping the seismic center at the center. Same process is done by three or more seismic centers. The point, where the circle drawn by three or more seismic centers meet is considered as the epicenter.

Hence, the correct answer is Three.

What term is used to describe bacterial cells that can naturally take up dna from their environment?
Maru [420]
<h2>The correct answer is: Competent cells</h2>

Explanation:

  • Bacterial cells have the capability of incorporating foreign naked DNA or deoxyribonucleic acid fragments from the environment or the exterior of the cell to the interior of the cell. This process is known as Transformation.
  • The bacterial cells which are able to undergo transformation are called Competent bacterial cells.
  • Some of the bacterial cells are naturally competent like<em> Bacillus subtilis, Streptocossus pneumoniae</em> while others  like <em>Escherishia coli </em>need to be chemically treated to make them artificially competent.
  • In natural competence, the foreign DNA from the cell exterior is incorporated into the cell interior through specific protein complexes present in the plasma membrane of the bacterial cells.
  • In artificial competence, the negative charge on foreign DNA is masked by positively charged calcium ions (so that it is not repelled by the negative charge of the lipid bilayer of the bacterial cell plasma membrane) and then small pores are created in the lipid bilayer of the plasma membrane of the bacterial cells by giving a heat shock to the cells. This results in the uptake of the DNA by the bacterial cells.

iren [92.7K]

Answer: The correct answer is - 3) olfactory receptors neurons that detect smell. 4) photoreceptors neurons that detect light .

1) and 2) statements are correctly matched in the question..

Olfactory receptors are also called odorant receptors. The olfactory receptor neurons detect smell and thus give a sense of smell to the organism. They are present in the nasal cavity.

Photoreceptor neurons are those that detect light and they are present in the retina of eye.
