Ecologist make models to be able to examine complicated environmental processes more readily and quickly.
Ecologists can also attempt to forecast what will happen in the future. Ecologists use the model to analyze natural events in order to better understand them.
An ecosystem model is an abstract, typically mathematical, representation of an ecological system (varying in scale from an individual population to an ecological community or even a whole biome) that is examined in order to get a better understanding of the real system.
There are two types of Ecologist Models;
(1) analytic models
(2) simulation / computational models.
Thus, to obtain understanding into complicated phenomena such as the consequences of global warming on ecosystems the ecologist make models.

A) ribosomes
B) Golgi bodies
C) mitochondria
D) endoplasmic reticulum
Answer:
The correct answer would be B) Golgi bodies
Golgi body is a cell organelle made up of vesicles and folded membranes.
It is mainly associated with the storage, modification, and packaging of macromolecules such as proteins and fats.
Macromolecules with the help of vesicles are transported from the endoplasmic reticulum to cis-Golgi bodies.
They are then modified in the folded membranes of the Golgi.
Post-modification they are transported to the different parts of the cell with the help of vesicles.
Viruses can replicate inside a host that they infect this is the reason why viruses do not have special structure or enzymes that allows them to make their own food. They just replicate and infect but they never make their own food.
Explanation:
Viruses depend on the host cells that they affect to reproduce. When found outside of host cells, viruses live as a protein coat or capsid, sometimes contained within a membrane. The capsid surrounds either DNA or RNA which codes for the virus elements.
Answer:
Because of insufficient number of offsprings to determine the result of test cross.
Explanation:
Normally, in genetics, a test cross is a cross between a dominant phenotype (genotype unknown) and a homozygous recessive genotype in order to determine the genotype of that dominant organism.
The result of the test cross is obtained when a 1:1 phenotypic ratio is produced for each trait i.e. 1 dominant trait: 1 recessive trait showing that the parent is heterozygous while all the offsprings will show dominant traits if the dominant phenotype was homozygous. Hence, more than one offspring is required to be able to conclude
In this question, the cow only produce one offspring which may be DOMINANT for the observed trait making it difficult to know if other offsprings will all be dominant or some of them recessive. Hence, it is not a sufficient number needed to determine the genotype from the phenotypic ratio of offsprings.
