what scientific term is used to describe all the genes of one organism?
Answer:
The scientific term used to describe all of the genes in an organsim is the genome.
Genome term is used to describe all the genes of one organism, it forms the genotype of an organism.
What is a genome?the entirety of an organism's genetic makeup, or DNA. Nearly every cell in a person's body has a complete copy of its genome. Everything a person needs to grow and develop is encoded in their genome.
Each and every one of the body's cells, such as the skin cell or the liver cell, carries the following set of instructions: DNA makes up the instructions in our genome.
The genome's main job is to preserve, express, and store the genetic material that gives rise to a cell's structural and functional machinery. The genome is a significant part of the cell's structural makeup, nevertheless. Hence, the Genome term is used to describe all the genes of one organism.

What is the microscopic nature of a cell ?
Why nucleus is said to be the controller of cellular activities ?
How is a cell adapted to its small size?
Answer:
No 1 answer They require sophiscated tools. The microscopes help in the study of cells. The molecular study of the cells are performed by the help of electron microscope. So, we can say that cells are microscopic in nature.
Explanation:
No 2 answer The nucleus is the largest and most prominent of a cell's organelles (Figure 3.7). The nucleus is generally considered the control center of the cell because it stores all of the genetic instructions for manufacturing proteins.
No 3 answer Smaller single-celled organisms have a high surface area to volume ratio, which allows them to rely on oxygen and material diffusing into the cell (and wastes diffusing out) in order to survive. The higher the surface area to volume ratio they have, the more effective this process can be.
3) In order for an ecosystem to thrive, it needs to exist in a form of harmony and balance between its biotic and abiotic factors. Describe how small changes to both biotic and abiotic components can have major effects on an ecosystem.
Answer:
Changing temperature causes extinction or removal of organism from that place.
Explanation:
Small changes to both biotic and abiotic components can have major effects on an ecosystem because these are the factors on which the ecosystem depends. For example, if the temperature of the ecosystem increases from its limit, it makes the environment unfavourable for the organism so due to this change, the organism migrated to other location otherwise they will die due to unfavourable environment.
Which statement best describes a characteristic of an ecosystem
Answer:
Infrastructure
Infrastructure is an important characteristic as it influences accessibility to the environment by land managers, and tourists alike. Unfortunately it can also increase the invasive potential introduced species, such as weeds and feral animals as road vehicles are well known to act as vectors for invasion of both weeds and feral animals. On the other hand roads improve access to implement various management programs, and also provide access for land users.
if the mass extinction event that had wiped out the dinosaurs had not occurred, could dinosaurs rather than mammals have evolved into an intelligent organism resembling modern day humans ?
Answer:
If the mass extinction even that had wiped out the dinosaurs had not occurred, dinosaurs would've evolved. Though maybe not into organisms that resemble modern-day humans, they would've become better versions of themself. However, some of them might've died out naturally due to climate change and other natural disasters.
If the mass extinction event had wiped out the dinosaurs and not occurred. The dinosaurs would not have been converted into an intelligent organism like humans, because evolution may be bad or good, nothing is always evolution that results in good traits.
What are dinosaurs?Dinosaurs are extinct reptiles, that were very big, and they were both herbivorous and carnivorous. These animals were present 56 million years ago. They got extinct because of an unknown reason, but scientists say that they got extinct due to the falling of meteorites.
If dinosaurs had not been extinct, they would be evolved according to the changes in the environment. They would not be converted into human intelligence.
Therefore, since evolution can be either positive or negative, there is no guarantee that it will always produce positive features in organisms, the dinosaurs would not have evolved into sophisticated beings like humans.
