Burning of fossil fuels adversely impacts on the water cycle that adversely affect the climate on Earth.

Human activity such as the burning of fossil fuels in vehicles and burning of wood for cooking have adverse effect on the earth's atmosphere. This burning of fossil fuels increase the temperature of the earth leads to global warming.

Raising the Earth's temperature means that there is an increase of evaporation, melting of glaciers and sea ice which imbalance the water cycle leads to flood and drowning of coastal regions of the earth so we can conclude that burning of fossil fuels adversely impacts on the water cycle that adversely affect the climate on Earth.

The release of heavy metal into the environment could possibly be dangerous because of pollution  be factored into the costs of using coal as an energy source

What are the types of energy ?

The energy can be defined as  ability to work or produce action and / or movement and manifests itself in many different ways, such as body movement, heat, electricity, etc.

The different types of energy include Kinetic energy which is associated with the movement of bodies. Potential energy which is  stored by virtue of a body's position relative to its surface is also called gravitational potential energy.

Thermal Energy or Heat can be defined as the energy  associated with the kinetic energy of the molecules that make up an element, it can be manifested if there is a temperature difference between two bodies.

Chemical energy released or formed from chemical reactions, Solar energy from sunlight. This form of energy is used to generate electricity through photovoltaic plates, for example.

The diagram shows an ocean food web. Which organism is a primary consumer? krill elephant seal Killer whale Elephant seal O squid O penguin Penguin Leopard seal Squid Cod Krill Zooplankton Phytoplankton​

Answers

Answer:

Krill

Explanation:

If you look at the diagram for this assignment, you can see the main organism that produces its own food is the phytoplankton. The animal that eats that organism is called a primary consumer. So, if you were to follow the arrow from the phytoplankton (or the producer), it would lead you to the zooplankton, krill, and cod. Since there are only one of these primary consumers as the choices, you would pick the only one available for the multiple choice, which would be krill :D

Answer:

A. krill

Explanation:

None of the other organisms are primary consumers.

Describe the rock layers shown in Diagram A and any forces acting on the rock.

Answers

The rock in diagram A has three horizons and no force acts on it.

What is a rock?

A rock is a geological term that refers to solid materials, made up of crystals or grains of one or more minerals. Rock is the main material in the Earth's crust.

Four diagrams of the Earth's crust are shown in the image. All four have three horizons and different forces influence them except A. These forces are caused by the movements of the Earth's lithosphere and are represented by arrows in the direction of movement.

In the case of diagram A, having no arrow means that no force acts on it. Additionally, you can see the three horizons or layers that make up this sample of land.

-It helps in the synthesizing of two new identical DNA strands from each parent strand
-It helps in the unwinding of DNA allowing for the formation of chromosomes during mitosis

Answers

The complementary nature of DNA rule ensures that only some particular base pairing are allowed and the DNA strands are complementary to each other.

The benefit of this complementary nature of DNA is that it helps in the synthesizing of two new identical DNA strands from each parent strand.

In DNA replication, the complementary nature of DNA ensures that following the production of new identical DNA strands, the composition of the new strands produced is intact and identical in composition.

How does myelin increase the speed of the action potential?

Answers

It insulates the axon and assembles specialized molecular structure at the nodes of Ranvier. In unmyelinated axons, the action potential travels continuously along the axons.

For example, in unmyelinated C fibers that conduct pain or temperature (0.4–1.2 μm in diameter), conduction velocity along the axon is 0.5–2.0 m/s (as fast as you walk or jog).

If an invasive species emigrated from a continent to a small island near the continent, what would most likely occur on the island

Answers

Answer:

Organisms on the island would migrate to a larger island.

Invasive species can cause extinctions, reduce biodiversity, compete for resources, and modify environments.

What is an invasive species?

An invasive species is a category of non-native species that has overtaken the habitat to which it was initially introduced.

Native plants and animals may go extinct as a result of invasive species, which can also decrease biodiversity, compete with native species for scarce resources, and disrupt habitats.

Preventative measures are the most practical and secure method of managing invasive species. It is far more effective to deal with invasive species early on and quickly than to try and contain an extensive infestation. The invasive species may be the target of control and management measures if eradication is not achievable.

A rise in __________ released from the sarcoplasmic reticulum allows actin to bind to myosin and cause a contraction, which requires __________ energy.

Answers

A rise in CALCIUM released from the sarcoplasmic reticulum allows actin to bind to myosin and cause a contraction, which requires ATP energy. ATP is the energy coin of the cell.

Adenosine triphosphate (ATP) is the energy coin that cells use to carry out many metabolic reactions (e.g., reproduction, motion, differentiation, etc).

The sarcoplasmic reticulum is an organelle located inside muscle cells similar to the smooth endoplasmic reticulum.
