Matter is recycled within and between ecosystems through closed loops called biogeochemical cycles. How is this unlike how energy is passed through ecosystems?

Answers

Answer:

Energy flows in a one-way direction i.e. unidirectional flow

Explanation:

Matter and energy both pass through an ecosystem as organisms feed on one another. However, as rightly emphasized in this question, matter in form of elements such as water, nitrogen, phosphorus etc. moves in different directions and is recycled within and between ecosystems through closed loops called biogeochemical cycles.

Contrarily to how matter is recycled in an ecosystem i.e. within and between, ENERGY only flows in one direction. Energy enters an ecosystem in form of light (sun) and is passed down from one trophic level to another starting from the producers. This unidirectional pattern of energy flow differentiates energy flow from matter recycling.

On one cactus species, the red flowers are dominant over white flowers. If you crossed two heterozygous cacti, what would be the probability of having offspring with red flowers?

Answers

Answer:

3/4

Explanation:

This question involves a single gene coding for flower color in cactus plant. The allele for red flowers (R) are dominant over the allele for white flowers (r). This means that a cactus that is heterozygous (Rr) for the Gene will possess a red phenotype.

In this cross, two heterozygous cacti are crossed. The following gametes will be produced by each heterozygous parent: R and r. Using these gametes in a punnet square, the following genotype of offsprings will be produced;

RR, Rr, Rr, and rr

RR, Rr and Rr are Red flowers (3/4)

rr are white flowers (1/4)

Therefore, the probability of having offspring with red flowers is 3/4.

What is the principle of superposition? A. The layers of sediment on the bottom are the oldest. B. All layers of sediment are identical. C. In a given region, all layers of sediment form at the same time. D. The geologic processes of today are very different from those in the past.​

Answers

Supperposition = the oldest layer in a sequence of undisturbed sedimentary rock is on the bottom

The principle of superposition is the layers of sediment on the bottom are the oldest. Hence option A is correct.

What is superposition?

Superposition is defined as a quantum system's capacity to exist in several states simultaneously up until it is measured. It is used to transform any circuit into its Thevenin or Norton equivalent. The theorem can be applied to networks of linear sources, linear passive elements, linear transformers, and linear dependent sources.

The original horizontality concept serves as the foundation for the superposition principle. According to the principle of superposition, each layer of sedimentary rock is older than the one above it and younger than the layer below it in a series of unaltered rocks.

Thus, the principle of superposition is the layers of sediment on the bottom are the oldest. Hence option A is correct.

Why is an electromagnet a temporary magnet?

Answers

Answer:

An electromagnet is a temporary magnet. It is made by winding a coil of insulated wire round a soft iron core. When a current is passed through the coil, the magnetic field produced by the current magnetises the soft iron core. The soft iron core loses all the magnetism when the current is switched off.

Explanation:

yes

Answer:

The magnetic field generated by the electromagnet only appears when there is an electrical current applied to it. The magnet field will disappear once the electrical current has left.

One thing that we did for her was make her a cancer/chemo basket after doing research. Apparently it tastes gross so you give them hard candy to suck on and there are certain things like ginger flavored ones or ginger smelling sticks that make you not be nasaus and hats in case she loses her hair (which they said she wouldn't) and a blanket with all of the family on it so she never has to be alone and stuff like that.

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.
