Symbiotic association means one of the organisms, called endosymbiont, is present inside the cells of its host. The most typical examples are endosymbiosis theory of mitochondria and chloroplasts which, according to some theories, are cellular organelles of bacterial origin.
But these theories are still discussed because there are in fact arguments that support endosymbiosis theory and also arguments that disapprove it.

Here are the answer for the exercise explaining the endosymbiosis
A ==> oxygen-using procaryote (before being a mitochondrion)
B ==> mitochondrion
C ==> Nucleus
D ==> endoplasmic reticulum
E ==> Host cell: ancestor of all eucaryotes
F ==> photosynthetic procaryote (before being a chloroplast)
G ==> chloroplast
H ==> Host cell: Ancestor for photosynthetic eucaryotes

The area affected by the ship that were involved in an accident is = 333 million liters

An oil spill can affect bird nesting near a contaminated body of water through its food chain.

<h3>What is oil spillage?</h3>

Oil spillage is defined as the release of used or oil wastes into a water body through a tanker, offshore drilling rig, or underwater pipeline.

The area affected by the ship that were involved in an accident can be calculated by the addition of the various areas affected by the tanker, ship and super tanker.

That is, 32,000 + 1,200,000 + 332,000,000

= 333,232,000

Which is approximately 333 million liters.

A bird that is nesting near the contaminated body of water can be affected through its food chain.

This is because birds which depends on fish can eat fish for this contaminated water which must have accumulated some level of harmful organic substances on its body surfaces.

Therefore when eaten by the bird their health would be affected negatively.

Discuss the order in which seed dispersal mechanisms could have evolved
sladkih [1.3K]

The fossil records of primitive plants show a variety of seed dispersal mechanisms that has been adopted by plants at various stages and how they have evolved. The most primitive of this seed dispersal mechanism is the Anemochory

Anemochory is the dispersal of seed through the wind. The seeds have wing like structures and are lightweight to be able to fly away with the wind. They are dull colored and are pale that will prevent the seed from being visible.

Hydrochory is the next order of evolution of the seed dispersal mechanism which became majorly adopted by plants that tend to grow near water sources and those whose seeds are too heavy to fly in the air. One of the best examples is the coconut that falls off on the sea water in the coastal areas and floats to other lands and sprouts to a new plant.

Barochory is the dispersal of the seed through gravity. This is the mechanism where the fruit falls off to the ground due to gravity and grows into a new plant.

Endozochory is the dispersal of the seed through animals. In this case the seed is usually covered with a fleshy edible part which is consumed by the animals and in this process the seed goes into the digestive system of the animal and is excreted in a different place from where the seed can sprout into a new plant.

Ballochory is the dispersal of the seed due to the forceful ejection of the seed by explosive dehiscence of the seed. This lets the plant to place its seeds in a distant area. One of the best examples is the Hura Crepitans which is also called the dynamite tree, named after its exploding fruits.
