Complete the Punnett square below by showing the genetic makeup of the parent plats of the cross shown.Be sure to show both genes for each parent.
Answers
Answer:
The correct answer is -
Parent 1: RW, Parent 2: RR
Explanation:
In the given punnet square there are four offspring and it is a monohybrid cross between parent 1 and parent 2. The four offspring produced in this cross have RR, RR, RW, and RW alleles. By the genotype of the offsprings, it is clear that there are 50 percent pure or true-bred and 50 percent are heterozygous.
Each parent contribute two alleles and these alleles are independently assort in the zygote to form offspring so there must be R, R, R and W allele present in the parent
Parent 2 → R R
Parent 1 ↓ R RR RR (one allele (R) come from each parent in zygote)
W RW RW (one allele (R and W) come from each parent)

Describe three levels of biodiversity
Answers
B
nba youngboy

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.

How do cells maintain homeostasis without using energy
Answers
Answer:
Form the cell membrane around food to create a vacuole that is kept separate from the rest of the cytoplasm while enzymes break down the food.
Cells maintain homeostasis without using energy by relying on passive transport processes.
Passive transport mechanisms do not require the input of cellular energy (ATP) and instead rely on the inherent kinetic energy of molecules and the concentration gradients of substances.
One common example of passive transport is simple diffusion, where molecules move from an area of higher concentration to an area of lower concentration until equilibrium is reached.
Similarly, facilitated diffusion utilizes protein channels or carriers to facilitate the movement of specific molecules across the cell membrane without energy expenditure.
Osmosis is another passive process where water molecules move across a selectively permeable membrane to balance the concentration of solutes on both sides.
By utilizing these passive mechanisms, cells can maintain a stable internal environment and achieve homeostasis without the need for energy expenditure.
