Answer:
Both diffusion and facilitated diffusion are driven by the potential energy differences of a concentration gradient. Glucose enters most cells by facilitated diffusion. ... Na+ is maintained at low concentrations inside the cell and K+ is at higher concentrations. The reverse is the case on the outside of the cell
Glucose continues to enter a cell, even when the concentration inside the
cell might be higher than outside as a result of the process known as active
transport.
Active transport involves the movement of molecules through a
cell membrane against the concentration gradient. Examples include:
Antiport Pumps.Symport Pumps.This type of transport requires the use of energy such as ATP to move the
glucose molecules into the cell.

Explanation:
During photosynthesis, plants and other photosynthetic organisms release oxygen into the atmosphere. Without this process, Earth's atmosphere would have little oxygen. Identify two reasons why photosynthesis is critical for animals to produce energy for life functions. How would this effect the animals ability to create the four main types of biomolecules.
Answer:
Without oxygen from photosynthesis animals would not have oxygen for the four type of biomolecules which all require oxygen. Carbon hydrogen and oxygen is carbohydrates and same for lipids. Proteins would not have the oxygen for CHON which is carbon hydrogen oxygen and nitrogen. And nucleic acids which are CHONP carbon hydrogen oxygen nitrogen and phosphorus would not have oxygen. And without oxygen the animals would die and not be able to produce these biomolecules.
Answer: To grow and reproduce, all creatures require energy. Cellular respiration is utilized by many organisms (including all plants) to create ATP, which is needed for cellular energy. As a substrate, carbohydrates such as glucose are used in the respiration reaction. Plants produce their own fuel for respiration through photosynthesis, but humans consume food to do so. Plants would not be able to breathe if photosynthesis did not occur. Furthermore, carbohydrates created during photosynthesis are needed to construct plant cell components such as the cellulose cell wall.

What is meant by a phenotype ratio in a Punnett square? (1 point)
A. the fraction of possible offspring that can be observed to have a trait
B. the number of genes that are possible in offspring
C. the number of alleles in possible offspring
D. the fraction of possible offspring that contain a certain allele in their genes
Given the nature of a punnet square, we can conclude that the ratio in question refers to the combination of genotypes present in the square.
A punnet square is a diagram used to attempt to predict the genetic composition for the offspring of certain parents, that is the genotype for this specific cross. This is done by creating a square in the form of a grid and placing the genotypes of the parents on the outside of this then crossing them along the inside.
This diagram provides us with the probability of each genotype outcome. This is known as the phenotype ratio. The phenotypic ratio is the amount of times a specific outcome, such as a certain pair of alleles appears in the predicted genotypes of any of the offspring pertaining to this cross.

NAME 3 SIMILARTIES AND 3 DIFFERENCES BETWEEN EACH OF THESE ZONES (AT LEAST 1 ABOTIC AND 1 BIOTIC FACTOR FOR EACH)
Sublittoral Zone & Epipelagic Zone
Abyssopelagic Zone & Hadalpelagic Zone
Neritic Zone & Oceanic Zone
Bathyal Zone & Bathypelagic Zone
Euphotic Zone & Aphotic Zone
Answer:
Like terrestrial biomes, aquatic biomes are influenced by a series of abiotic factors. The aquatic medium—water— has different physical and chemical properties than air. Even if the water in a pond or other body of water is perfectly clear (there are no suspended particles), water still absorbs light. As one descends into a deep body of water, there will eventually be a depth which the sunlight cannot reach. While there are some abiotic and biotic factors in a terrestrial ecosystem that might obscure light (like fog, dust, or insect swarms), usually these are not permanent features of the environment. The importance of light in aquatic biomes is central to the communities of organisms found in both freshwater and marine ecosystems.
Explanation:
The ocean is categorized by several areas or zones (Figure 1). All of the ocean’s open water is referred to as the pelagic zone. The benthic zone extends along the ocean bottom from the shoreline to the deepest parts of the ocean floor. Within the pelagic realm is the photic zone, which is the portion of the ocean that light can penetrate (approximately 200 m or 650 ft). At depths greater than 200 m, light cannot penetrate; thus, this is referred to as the aphotic zone. The majority of the ocean is aphotic and lacks sufficient light for photosynthesis. The deepest part of the ocean, the Challenger Deep (in the Mariana Trench, located in the western Pacific Ocean), is about 11,000 m (about 6.8 mi) deep. To give some perspective on the depth of this trench, the ocean is, on average, 4267 m. These zones are relevant to freshwater lakes as well.
The ocean is the largest marine biome. It is a continuous body of salt water that is relatively uniform in chemical composition; it is a weak solution of mineral salts and decayed biological matter. Within the ocean, coral reefs are a second kind of marine biome. Estuaries, coastal areas where salt water and fresh water mix, form a third unique marine biome.
The intertidal zone, which is the zone between high and low tide, is the oceanic region that is closest to land (Figure 2). Generally, most people think of this portion of the ocean as a sandy beach. In some cases, the intertidal zone is indeed a sandy beach, but it can also be rocky or muddy. Organisms are exposed to air and sunlight at low tide and are underwater most of the time, especially during high tide. Therefore, living things that thrive in the intertidal zone are adapted to being dry for long periods of time. The shore of the intertidal zone is also repeatedly struck by waves, and the organisms found there are adapted to withstand damage from the pounding action of the waves (Figure 2). The exoskeletons of shoreline crustaceans (such as the shore crab, Carcinus maenas) are tough and protect them from desiccation (drying out) and wave damage. Another consequence of the pounding waves is that few algae and plants establish themselves in the constantly moving rocks, sand, or mud.

11. A flower produces a seed. Explain why this is an example of sexual reproduction
Answer:
itrequires genetic material (DNA) from two parents. The parent plants have male and female sex cells, called gametes. ... Seeds produced through fertilization contain genetic material from both parents.
The production of a seed by a flower is an example of sexual reproduction because it involves the fusion of male and female gametes (pollen and ovules) to form a genetically diverse offspring.
Sexual reproduction is a type of reproductive process that involves the combination of genetic material from two parent organisms, resulting in the formation of genetically diverse offspring. In the case of a flower producing a seed, sexual reproduction occurs through a series of specialized reproductive structures and processes.
Male Gamete Production (Pollen): Flowers produce male gametes, or pollen, in structures called anthers. Pollen contains the male reproductive cells necessary for fertilization. When pollen is mature, it is released from the anthers.
Female Gamete Production (Ovules): Flowers also produce female gametes, or ovules, within the ovary. Each ovule contains an egg cell, which is the female reproductive cell. The ovary is located at the base of the flower.
Pollination: Pollination is the process by which pollen from the male reproductive structures (anthers) is transferred to the female reproductive structures (stigma) of the same or a different flower. This can occur through wind, water, insects, birds, or other means.
Fertilization: Once pollen lands on the stigma of a compatible flower, it forms a pollen tube that grows down into the ovary. This tube delivers the male gametes to the ovules, where fertilization occurs. Fertilization is the fusion of a male gamete with a female gamete to form a zygote, which develops into an embryo within the seed.
Seed Formation: After fertilization, the ovule develops into a seed, which contains the embryo, endosperm, and protective seed coat. The embryo carries genetic information from both parent plants, resulting in genetic diversity.
The combination of genetic material from male and female parent plants results in offspring with unique genetic characteristics. This genetic diversity is advantageous for the survival and adaptation of species to changing environments. Therefore, the production of a seed by a flower is a prime example of sexual reproduction, involving the fusion of gametes to create genetically diverse offspring with traits inherited from both parents.

why is a floating ice layer important to aquatic organisms?
Answer:
It helps life survive on Earth.
Explanation:
Since water ice floats, it helps life survive on Earth. This ice layer insulates the water below it, allowing it to stay liquid, which allows the life within it to survive. If ice sank, the liquid water on top would also freeze and sink, until all the liquid water became frozen.
