The molecule that can MOST easily pass through the plasma membrane without assistance is carbon dioxide (CO2). Diffusion is a type of passive transport that occurs when molecules move in favor of a concentration gradient.
During diffusion, molecules move high concentration to a region of low concentration.
Oxygen (O2) and carbon dioxide (CO2) are non-polar gasses that move across cell membranes by a process called simple diffusion.
Simple diffusion is a type of passive transport that does not require energy to move substances across cell membranes.

Answer:
thanks i need more point bopleals
The correct option is (A) in biomes at different latitudes.
When climbing a mountain, we can observe transitions in biological communities that are analogous to the changes in biomes at different latitudes.
<h3>
What is biome?</h3>
- A naturally existing species community that is influenced by a region's climate and latitude is referred to as a "biome."
- A place where two biological communities come together and merge is known as an ecotone. It could be small or large, local (the area between a field and a forest), or regional (the transition between forest and grassland ecosystems).
- As you ascend a mountain, different sections experience varying amounts of sunlight and warmth. People see differences in the biological community as an organism ascends a mountain because different latitudes are present.

Answer:
Chromosome number variation: B. Down syndrome
Loss-of-function allele : D. PKU
Physiological trait
: E. Lactose metabolism
Discovery-based science
: A. Human Genome Project
Genetic cross: C. Model organism
Explanation:
Down syndrome is a condition in which there is an extra copy of the chromosome number 21. Hence, it is a chromosome number variation.
Physiological traits refers to any function of a body. Hence, it matches with lactose metabolism.
Human Genome Project was a project under which the whole genome of the humans were sequenced. Hence, it is a discovery based science.
A genetic cross is made between model organisms to test for the offsprings that would be produced from a cross. Hence, genetic cross and model organism math with each other.

The population of the Florida panther once dwindled to below two dozen, but it has since rebounded to more than 200
<h3>What is the panther population in Florida ?</h3>
Today there are only 120 to 130 Florida panthers left in the wild. They are found in southern Florida in swamplands such as Everglades National Park and Big Cypress National Preserve
- Florida's largest wild cat species, the panther is critically endangered, but has been making a slow and steady comeback since numbers sunk to just 20 individuals in the 1970's. As of 2021, most estimates place the present day population at around 200.
- By far the greatest threats to Florida panthers are habitat loss, fragmentation and degradation — all driven by Florida's burgeoning human population and the developments and highways that accommodate it.
