An amoeba is a single-celled organism that feeds on algae, plant cells, and bacteria. When an amoeba feeds, it first makes conta

ct with the food particle. Next, the amoeba starts to surround the particle. Once the particle is completely engulfed, it is surrounded by a layer of the amoeba's membrane, forming a vesicle. the pH in the vesicle is then lowered and the contents are degraded. What type of transport is involved in this process?
A. diffusion
B. endocytosis
C. exocytosis
D. passive transport​

Answer:

The answer is: D. Passive transport

Explanation:

Passive transport refers to the movement of chemical substance that pass through the cell membrane without using any energy, This ability exist in all living cells and utilizing the process of osmosis to move from a less concentrated environment to a more concentrated one.

devlian [24]

Answer:

The correct answer is option A, that is, cotransport proteins.

Explanation:

The variable that possesses the tendency to mediate energy based on chemical potential is termed as an electrochemical gradient. The electrochemical gradient is differentiated into two parts, that is, electrical gradient and chemical gradient. Both these forms of gradient take place over the surface of a membrane.  

The movement of the majority of the ions takes place by the phenomenon of electrochemical gradients, of which some are found on the surface of the membrane and function as electrogenic pumps. While the gradients of some of the ions are mostly accounted for by the co-transport proteins, as these proteins take part in the movement of ions or molecules through a plasma membrane that involves concentration gradient based on the kind of molecules and movement.

Aleksandr [31]

Answer:

The correct answer is "True".

Explanation:

The zebra mussel is a small animal that lives near freshwater zones, just like the ones present at the Hudson River of New York. In this place is where zebra mussel was first detected in May 1991. However, it had been traced that zebra mussel is originally native to the Black and Caspian Seas of Asia. It is believed that zebra mussel arrived to New York in the mid-1980s in the ballast water of ocean-going ships that came from Europe.

Why is it necessary to correct the readings of the respirometers containing seeds with the readings taken from respirometers con
amid [387]
So, the fact that it's a specific instrument doesn't change why you need to correct the data.
However, for this question it is important to know the instrumentation.
Since respirometers are measuring the <span>C<span>O2</span>:<span>O2</span></span><span> relation, clearly having biotic material and abiotic material will change the measurements.
You should be able to figure out that the general gas law is coming into effect because of the act of cellular respiration. In general terms, you are correcting your instrument to a known blank (you do this with scales and every other instrument).
By determining the reading for the blank (marbles) you can know the relative error of the instrument.
Taking a scale for example: You 0 the scale to a mass of importance (the amount of error you're okay with) and then use it for your measurements so you can be adequately confident of the mass you're measuring .</span>

On an island, finches that fed on large, hard seeds had large beaks. Finches with small beaks fed on small, soft seeds. A drough
Stolb23 [73]

Answer:

The correct options are:

  • <em>The population of birds with large beaks will increase on the island.</em>
  • <em>The trait for large beaks will be passed on to future generations through natural selection.</em>

Explanation:

According to the theory of natural selection, those organisms tend to survive in an environment which are better adapted to live in an environment and which can better adapt to changes that occur in an environment.

The drought caused the small, soft seeds to decrease more in number as compared to the large, hard seeds. As a result, the birds having large beaks were better adapted to live in the environment as compared to the birds having small beaks. So the population of the large beak birds increased and they passed their characteristics to the future generations.
