"No biological system is completely closed, thus some movement of nutrients in and out always occurs." Is this statement true or

false?
Biology
1 answer:
Gemiola [76]3 years ago
3 0

Answer:

TRUE

Explanation:

No biological system is completely closed.

A nutrient cycle is the movement and exchange of both organic and inorganic matter back into the production of matter. This cycle is a recycling system which always occurs no matter what.

In a system that looks closed (closed loop), nutrients may be limited because they are not cycled through  the system fast enough and/or it is not possible to compensate for deficiencies by  migration.

Mnenie [13.5K]

Answer: It has multiple nuclei, It is one of the smallest of cells with among the smallest of genomes.

Explanation:

Mycoplasma mycoides is a bacterial strain of the genus Mycoplasma. It belongs to the class of Mollicutes. This is parasitic in nature. It lives in the ruminants.  It is smallest known bacteria that does not posses the cell wall. It is present everywhere as a pathogen. It's function is to interfere with the ability of the virus to affect the mammalian cells. It posses multiple nuclei.

It is smallest free-living single celled organism. Due to the small size the entire genome can be sequenced. It can be useful for purpose of research and it is of particular interest because of it's small cell size and multiple nuclei. It serves as a model organism to study the bacterial evolution.

Movement of the chromosomes during anaphase would be most affected by a drug that
My name is Ann [436]

Answer:

The options are missing, the options are:

A) prevents the duplication of centrosomes. B) prevents nuclear envelope fragmentation C) prevents shortening of microtubules. D) prevents attachment of the microtubules to the kinetochore. E) prevents nucleosome formation

The answer is C

Explanation:

Cell division is a characteristics of all living cells. Whether meiosis or mitosis, the chromosomes separate in the Anaphase stage. Prior to the anaphase stage is the metaphase, where spindle microtubules attach to the kinetochores of each chromosome and aligns them at the centre of the cell called METAPHASE PLATE.

Thus, since the aligning of chromosomes at the metaphase plate has to do with attachment of microtubules to chromosomes' kinetochores, the drug that will hinder movement of chromosomes to opposite poles will not stop formation of microtubules. Instead, it will prevent the formed microtubules attached to each chromosome from shortening, as it is the shortening of microtubules that facilitates the pulling apart of the chromosomes they are attached to.
