both the molecules are too small and have no charge therefore they can move across a membrane via gradient pressure from higher concentration to lower via simple diffusion. they don't need any atp or energy.
O2 and CO2 are both nonpolar molecules that can easily pass through the hydrophobic interior of a membrane! Hope it helps
The different forms a gene may have for a trait are called alleles. These are variations of a gene present on homologous chromosomes. A trait in an individual is determined by the two alleles inherited from their parents.
The different forms a gene may have for a trait are called alleles. These are variations of a gene that occur at the same relative locations on homologous chromosomes. For example, in a diploid organism where a single gene controls a characteristic, there can be two genetic copies, or alleles, that may or may not encode the same version of that characteristic.
A slight change in the sequence of nucleotides within a gene can result in different alleles that code for different traits. For instance, the different alleles for the gene that determines blood type in humans are sequence A, sequence B, and sequence O. The blood type is a trait determined by the two alleles that are inherited from the parents.
It's important to note that while an individual can only have two alleles for a given gene, it's common in a natural population to encounter more than two alleles for any given gene, a phenomenon referred to as multiple alleles.

B) accessing food
C) obtaining oxygen
D) avoiding predators
Answer:
The answer is C
Explanation:
Because in order for it to breath well it needs to move its gills
White tip reef sharks pump water across their gills to obtain oxygen.
White tip reef sharks spend most of the day lying on the ocean floor. They pump water across their gills while remaining still, as the movement of water across their gills is necessary for obtaining oxygen. Gills in fish, including sharks, absorb oxygen from the water as it passes over them. Sharks have well-developed sense organs that aid them in locating prey, including a keen sense of smell and the ability to detect electromagnetic fields.
Electroreceptors called ampullae of Lorenzini allow sharks to detect the electromagnetic fields that are produced by all living things, including their prey. The lateral line is used to detect movement and vibration in the surrounding water, and is often considered to be functionally similar to the sense of 'hearing' in terrestrial vertebrates.

Answer:
Asexual reproduction is a method of reproduction for most of single cell organisms including yeast, in this type of reproduction a single parent generates new organism and new one is exact copy of parent both physically and genetically.
In yeast asexual reproduction is carried out by budding, its an asymmetric type of division in which first a protruding body is produced on its surface, it fully grows and forms bud later. When full grown, buds detach from the parent cell and grows independently. Instead of single bud, a chain of buds could also be produced at the surface of yeast.
