Answer:
Very necessary for its survival.
Explanation:
Movement of molecules is very important to maintain a healthy cell environment because some molecules are required by the cell for its growth and development. Some molecules moves inside the cell environment through a semi-permeable membrane such as glucose, oxygen, potassium etc while on the other hand, some molecules are removed from the cell which are waste materials such as carbondioxide etc. If these waste materials are not removed from the cell, it greatly damaged the cell.
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.

Why do many water animals not have a well developed blood system?
The simplest animals, such as the sponges (Porifera) and rotifers (Rotifera), do not need a circulatory system because diffusion allows adequate exchange of water, nutrients, and waste, as well as dissolved gases. Instead, gases, nutrients, and wastes are exchanged by diffusion.

C. Polar bears have white fur to help them blend into their surrounding
environment
D. Whales have a thick layer of fat called blubber to help keep them warm
Answer:
B. Elks attatch leaves and grasses to their antlers to help them appear larger.
Explanation:
Reason 1: If the Elk appears larger other male Elks would be too scared to fight that Elk for a female. Reason 2: The female Elk will be more attracted to the larger male Elk even if it's largeness is fake.

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.

How is the water and boiling point of water useful to us
Answer:
The boiling point of water can be used to illustrate the importance of hydrogen bonds in living systems. The boiling point of a compound is the temperature at which a liquid becomes a gas. When the temperature is high enough to separate the individual molecules from each other, they boil, or become a gas.

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.
what happens to the energy that is not converted to usable energy in a muscle Cell?
Answer:

A. Meiosis
B. DNA Replication
C. Crossing Over
Answer:
C. Crossing Over
Explanation:
Crossing over, also called recombination, is the process by which non-sister chromatids of homologous chromosomes exchange a segment of their chromosomal material with one another. The process of crossing over occurs only in the prophase I stage of meiosis.
The process is responsible for genetic variation in the gametes produced, thereby, leading to organisms that are genetically unique.

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.
