What evidence supports the law of conservation of energy?

Biology

d1i1m1o1n [39]3 years ago

The right answer is C

I will explain the law of conservation of energy by photosynthesis:

The conservation principle states that the energy of an isolated system (chlorophyll) can not vary.

On the other hand, if the system is not isolated (it is in the nature, exposed to the sun), that is to say if it can exchange with the outside, (the chlorophyll will absorb the photons put by the Sun). Thus the system transforms this absorbed energy into another form (glucose in the case of photosynthesis).

A new island formed by volcanic action may eventually become populated with biotic communities. describe the type of ecological
Katyanochek1 [597]

The type of ecological succession being described in the illustration is primary succession.

<h3>What is primary succession?</h3>

It is a form of succession that occurs when an area that has never been occupied by any living organism becomes exposed and eventually gets colonized by living organisms.

It is quite different from secondary succession which happens when an area that has been housing biotic communities before gets disrupted by a major disturbance.

A new island formed by volcanic action has never housed any biotic community before. Thus, only primary succession can occur there.

Which of the following is NOT a land resource?
julsineya [31]

Answer: d. the wind

Wind is not a land resource. It is the natural movement of air across the earth surface. Wind is also considered as movement of gases present in the atmosphere. The strength and direction of wind can be measured. It is a atmospheric resource. Wind produces as a result of difference in the atmospheric pressure. When a difference in atmospheric pressure exist air  moves from region of high pressure to low pressure area. Wind energy is renewable source of energy can be used to produce electrical energy.

What are convergent boundaries?
boyakko [2]

Answer:

Explanation:

A convergent boundary (also known as a destructive boundary) is an area on Earth where two or more lithospheric plates collide. One plate eventually slides beneath the other, a process known as subduction. The subduction zone can be defined by a plane where many earthquakes occur, called the Wadati–Benioff zone.[1] These collisions happen on scales of millions to tens of millions of years and can lead to volcanism, earthquakes, orogenesis, destruction of lithosphere, and deformation. Convergent boundaries occur between oceanic-oceanic lithosphere, oceanic-continental lithosphere, and continental-continental lithosphere. The geologic features related to convergent boundaries vary depending on crust types.

Plate tectonics is driven by convection cells in the mantle. Convection cells are the result of heat generated by radioactive decay of elements in the mantle escaping to the surface and the return of cool materials from the surface to the mantle.[2] These convection cells bring hot mantle material to the surface along spreading centers creating new crust. As this new crust is pushed away from the spreading center by the formation of newer crust, it cools, thins, and becomes denser. Subduction begins when this dense crust converges with less dense crust. The force of gravity helps drive the subducting slab into the mantle.[3] As the relatively cool subducting slab sinks deeper into the mantle, it is heated, causing hydrous minerals to break down. This releases water into the hotter asthenosphere, which leads to partial melting of asthenosphere and volcanism. Both dehydration and partial melting occurs along the 1,000 °C (1,830 °F) isotherm, generally at depths of 65 to 130 km (40 to 81 mi).[4][5]

Some lithospheric plates consist of both continental and oceanic lithosphere. In some instances, initial convergence with another plate will destroy oceanic lithosphere, leading to convergence of two continental plates. Neither continental plate will subduct. It is likely that the plate may break along the boundary of continental and oceanic crust. Seismic tomography reveals pieces of lithosphere that have broken off during convergence

Helper t cells interact with target cells by recognizing __________.
cupoosta [38]

Answer:

antigen-MHC protein complexes

Explanation:

Helper T-cells recognise antigens that are complexed with MHC proteins and interact with target cells. Antibodies can be produced against a single antigen in a variety of ways. Toxic shock syndrome is a relatively mild condition that resembles other minor allergy responses. Antigen-presenting cells break down superantigens.
