What is the BEST explanation of how two organelles work together to maintain homeostasis within a cell? A) Golgi bodies (#3) sort, refine, and package lipids used by the ER (#7) when making proteins.


B) Ribosomes (#1) manufacture proteins to be broken down for immediate energy by the mitochondria (#2).


C) Chloroplasts (#2) convert solar energy to make simple sugars which are then used by the mitochondria (#5) to provide energy for the cell.


D) Mitochondria (#3) produce energy molecules which are digested by lysosomes (#8) to provide energy for cellular processes.

Answers

The best explanation of how two (2) cell organelles work together to maintain homeostasis within a cell is: C) Chloroplasts (#2) convert solar energy to make simple sugars which are then used by the mitochondria (#5) to provide energy for the cell.

A cell refers to the fundamental (basic) functional, structural and smallest unit of life for all living organisms. Some examples of cell organelles found in all living organisms include;

  • Nucleus.
  • Mitochondria.
  • Lysosomes.
  • Chromosomes.
  • Ribosomes.
  • Endoplasmic reticulum.
  • Cytoskeleton.
  • Vesicles.
  • Golgi apparatus.
  • Cell membrane.
  • Chloroplasts.

Homeostasis can be defined as a biological process through which a living organism maintains a stable (steady) an internal, chemical and physical environment that is ideal to sustain life and enhance proper functionality.

In Plants, homeostasis takes place into two (2) distinct stages;

I. Chloroplasts convert solar energy to make simple sugars through photosynthesis.

II. These simple sugars are then used by mitochondria to provide the required amount of energy for the cell.

Question 1 (1 point)Which sequence best orders ecological categories from the one with the fewest number of individuals to the one with the greatest number of
individuals?
OOOO
ecosystem, population, community, biome
biome, population, community, ecosystem
population, community, ecosystem, biome
community, biome, population, ecosystem

Answers

Population, community, ecosystem, biome is the order of the individual numbers.

Explanation:

A population is defined as the group of same species in a particular area that live together and depend on same kind of food with same reproductive habits.

The community is defined as the collection of all the living organisms in a particular region. All the different species residing in a particular habitat is considered as the community.

The ecosystem consists of the both living and the non living objectsorganisms in a particular region. All the living organisms as well as the soil, rock, wind etc forms the ecosystem of a region.

The biome is defined as the large geographical region where the different organisms reside and it also gives an idea about the geographical features of the region.
