Answer:

The correct answer is b) they are capable of photosynthesis.

Explanation:

Euglenas are a group of flagellated protists commonly found in fresh water. As you can see from the picture, one of the organelles found in the cytoplasm is chloroplast and this organelle is directly involved in photosynthesis process. So, as Euglena has chloroplast the correct option must be that they are capable of photosynthesis.

Facilitated diffusion occurs

Alex777 [14]

Facilitated diffusion occurs in the cell body. It is the process of transporting particles into and out of a cell membrane. Energy is not required because the particles move along the concentration gradient. Permeable means that particles, ions, or water can cross the membrane. Hope I’ve helped ;)

The water cycle always begins with?

ddd [48]

It always starts with evaporation, because without water vapor (the byproduct of evaporation), there would be no clouds (they are made out of water vapor and some other particles). Henceforth, there will be no rain.

How does natural selection or human evolution affect disease susceptbility

devlian [24]

<span>Investigations of the legacy of natural selection in the human genome have proved particularly informative, pinpointing functionally important regions that have participated in our genetic adaptation to the environment. Furthermore, genetic dissection of the intensity and type of selection acting on human genes can be used to predict involvement in different forms and severities of human diseases.</span>

Which part of the cell theory do these results most support:

Vlad1618 [11]

<h2>Hey There!</h2><h2>_____________________________________</h2><h2>Answer:</h2><h2>_____________________________________</h2>

$\huge\textbf{Cell Theory}$

the Cell Theory was give by German scientists, Schleiden and T.Shwan in 1839. It stated that,

All organism are composed of one or more cells

The cell is the structural and functional unit of life
It is a de novo structure, that means it COULD arise from non living thing which was incorrect.

It was corrected by the German pathologist Rudolf Virchow in 1855. He made a convincing case, corrected and added the third point of the cell theory. It is,

Cells can arise only by a division of pre-existing cell. It is <u>NOT</u> a de novo structure.

Cell theory brought a great evolution in the field of biology which established the function of organism is the result of activities and interaction of the cell units.

$\huge\textbf{Question:}$

<u>Flask 1</u>: It is observed that there are no micro-organism, this is because the meat is sealed and no micro-organism could enter through it.
<u>Flask 2</u>: It is observed that there are micro-organism present because meat is not sealed but open.
<u>Flask 3</u>: As the S tube is used, the micro-organism are not able to reach the meat because of the curvy path

These observations support the point that<u> cells could arise only by a division of pre-existing alive cells</u> because in Flask 1 when there were no micro-organism present so there was no organisms found so no micro-organism arised, In flask 3 the S tube was used so no micro-organism could reach the meat thus there were no organism there which could divide to reproduce. The flask 2 was open, so the micro organisms reached the meat so they divided which means Cells can only arise by a division of pre-existing cells.
