Answer:
The cells specialized in passive diffusion have a greater amount of membrane structures called transport proteins.
Explanation:
Facilitated diffusion is a transmembrane transport mechanism, which consists of the passage of substances through the cell membrane by means of a transporter.This process does not require energy, as it is a passive transport, and depends on an ionic gradient or concentration.
The carriers of facilitated diffusion can be integral membrane proteins, so a cell specialized in this type of transport must have abundant transport proteins.

B. Polar Bear to Seal to Fish to
Seaweed to Bacteria
C. Bacteria to Seaweed to Fish to Seal
to Polar Bear
D. Seaweed to Bacteria to Seal to Fish
to Polar Bear
Answer:
C. Bacteria to Seaweed to Fish to Seal to Polar Bear
Explanation:
Every ecosystem consists of multiple organisms. These organisms feed on each other, forming a food chain. The energy within an ecosystem flows through the food chain.
Here, we're supposed to determine which food chain is the correct one. All organisms can be divided into producers and consumers. Producers are organisms that produce their own food, while consumers feed by consuming other organisms.
The only food chain that makes sense is shown in option C. I wouldn't say that bacteria belong to it as the seaweed is an example of a producer. It doesn't consume other organisms. But, fish feed on it, then seals eat the fish, and polar bears eat the seals. This is why we can safely say that option C is the correct one, despite bacteria being present there. Any other combination wouldn't work as, for example, bacteria (A) and seals (B) can't eat polar bears and the fish can't eat seals (D).

Michaela spend the day at the lake with some friends. She spends some time exploring the lake as she looks around she notices that there are plants only in certain areas where would she see plants growing? Why?
Answer:
She would mostly see plants grow around the banks of the lake. In addition, she might see some plants growing in the lake. The plants are majorly aquatic plants. The ones on the banks are emergent plants because their roots are submerged in water and their foliage is above water. They grow on the shores because it shallow there. Free-floating aquatic plants may grow in the lake because they are suspended on the water surface with their roots just floating underneath the water surface.

meiosis II.
Answer:
Meiosis I
Explanation:
The separation of homologues occurs during meiosis I. The Option A.
When does the separation of homologues occur during cell division?During meiosis I, the process of cell division specifically designed for the formation of gametes, the separation of homologous chromosomes occurs. Meiosis I consists of several phases including prophase I, metaphase I, anaphase I, and telophase I.
In prophase I, homologous chromosomes pair up and exchange genetic material through a process called crossing over. During metaphase I, the pairs of homologous chromosomes align at the center of the cell. Then, in anaphase I, the homologous chromosomes separate and move toward opposite poles of the cell.

Describe three levels of biodiversity
The three levels of biodiversity are genetic diversity, species diversity, and ecosystem diversity.
Genetic Diversity: Genetic diversity refers to the variety of genes within a species. It includes the different alleles and variations present in the gene pool of a population. Genetic diversity is important because it provides the raw material for adaptation and evolution. A higher genetic diversity within a species increases its ability to survive and thrive in changing environments. It also helps in disease resistance and overall population health.
Species Diversity: Species diversity refers to the variety of different species present in a particular area or ecosystem. It measures the number of different species and their relative abundance. Higher species diversity indicates a healthier ecosystem and greater ecological resilience. Each species plays a unique role in the ecosystem and contributes to its stability and functioning. Loss of species diversity can disrupt ecosystem balance and lead to negative impacts on other species and ecosystem processes.
Ecosystem Diversity: Ecosystem diversity refers to the variety of different ecosystems or habitats within a region or on a global scale. It encompasses the different types of ecosystems such as forests, grasslands, wetlands, coral reefs, and more. Each ecosystem has its own set of species, interactions, and ecological processes. Ecosystem diversity is essential for maintaining ecological functions, nutrient cycling, and providing various ecosystem services such as clean air, water, and food. It also supports the resilience and adaptability of ecosystems to environmental changes.
These three levels of biodiversity are interconnected and mutually dependent. They provide the foundation for the functioning and sustainability of our planet's ecosystems. Protecting and conserving biodiversity at all levels is crucial for the well-being of both human populations and the natural world.

All cells can synthesis ATP by way of glycolysis. Many cells have to metabolize pyruvate without oxygen by doing...?
Answer:
Anaerobic respiration
Explanation:
As rightly stated in this question, cells of all living organism synthesize ATP via the process of cellular respiration. Cellular respiration, however, occurs in stages starting with GLYCOLYSIS, which breaks down glucose to form PYRUVATE.
The metabolism of pyruvate in subsequent steps depends on whether the respiration process is occuring with or without oxygen. Without oxygen, pyruvate is metabolized in a process called ANAEROBIC RESPIRATION. Anaerobic respiration employs other molecules asides OXYGEN for last electron acceptor.

Answer:
As a metabolic heat.
Explanation:
The loss of energy from one trophic level to the next in a food chain occurs because energy is lost in the form of heat when the organisms from one trophic level are consumed by organisms from the next level. Only 10% of energy is transferred from one trophic level to another while the remaining 90% energy is lost in the form of heat energy in the ecosystem.

Why are metamorphic rocks usually harder and denser than their parent rocks?
Answer:
Explanation:
Metamorphic rocks are harder and denser than their parent rocks because they started off the same as their parent rocks but at some point were met with extreme heat and pressure. These conditions melted and compressed the parent rocks so much that it created metamorphic rock that was extremely hard and dense. This is why metamorphic rocks are usually found deep under the Earth's surface.
There are different types of rocks depending on their size, composition and location.
They are harder and denser than their parent rock because of tremendous radiation and temperature.
They are the rocks that are produced from the before developed rocks through the process of transformation.They get modified due to the high heat and pressure found in the deepness of Earth.The process of metamorphosis includes melting of the parent rock which later gets harder.Therefore, metaphoric minerals are found deep inside the Earth.
