Answer:

The correct answer is "II. peroxisomes, I. mitochondria, and III. lysosomes".

Explanation:

The differences in organelles density are utilized for purification purposes, creating density gradients that helps to isolate each organelle separately. The correct order of organelles from most dense to least dense is: peroxisomes, mitochondria, and lysosomes. Peroxisomes have a density of around 1.19 g/ml, mitochondria of around 1.07 g/ml, and lysosomes of around 1.04 g/ml.

Glycolysis occurs in the mitochondria protoplasm cytoplasm of the cell.

dmitriy555 [2]

Glycolysis occurs in the cytoplasm of the cell. You can remember this because even prokaryotic cells can do glycolysis so it must occur without a membrane bound organelle such as a mitochondrion.

Rabbits, turtles, fish, humans, and whales all share certain characteristics but also differ from each other. All of these speci

Delvig [45]

The levels of organisation are

Domain: Eukarya

Kingdom Animalia

Phylum :Chordata

Explanation:

They all share these levels of organisation because;

for the Domain Eukarya, they have;

→multi-cellular cells containing nucleus; and other membrane bound organelle.e.g Mitochondrial.

→their DNA located in the nucleus packaged as linear chromosomes bounded by histone proteins.

→mode of reproduction which is sexual.

They share Kingdom Animalia because;

→they have multi-cellular, specialised cells, bounded by plasma membranes.

→they have specialized tissues, organs, and system.

→they all undergo heterotrophic mode of nutrition as evident in the question 'that they must consume plants and animals as source of energy'

→they exchanged communication by nervous ssytem and 

→ use homeostatic mechanisms to regulate water balance of the body through the kidney.

→Humans,Rabbits,and whales are VIVIPAROUS; they give birth to young ones alive.

→Most fishes lay eggs to reproduce, they are said to be Ovoviviparous.

They belong to phylum Chordata because ;

→they all have noto chord; which serve as template for axial skeleton.

dorsal hollow nerve cord -template for the brain and spinal cord

→pharyngeal slits- templates for gill aches in bony fishes and components of inner ear in land animals.

→ tail length varies in these organisms.

The density of gas particles in a section of Earth’s atmosphere decreases. Which of the following is the most likely explanation

aalyn [17]

Answer:

A. The air pressure in that section of Earth’s atmosphere decreased. 

Explanation:

In the free air, the density of the air diminishes as the air is warmed. On increasing the pressure, the density also increases. The air is packed. The density increments as pressure increments.

The thickness and density of air decline with the increase of height because of that the surface area of the Earth's climate diminishes with increase in height, along these lines gas particles can spread out.

The density of the air is most minimal at a high rise on a hot day when the pressure of the atmosphere is low.
