Using energy as the factor, what case can be made for eating vegetarian?

Shkiper50 [21]

Explanation:

One of the benefits of a vegetarian diet is a reduction in your impact on the environment. Animals store only a small fraction of the energy they extract from the food they eat, and the rest is wasted as heat.

Decomposers are important because they

eimsori [14]

Answer:

Decomposers and scavengers break down dead plants and animals. They also break down the waste of other organisms. Decomposers are very important for any ecosystem because if they weren't in the ecosystem, the plants would not get essential nutrients, and dead matter and waste would pile up.

Arrange the following events in the order in which they occurred.

Mumz [18]

Answer:

1→4→5→3→2

∙

Mitotic cell division starts with the condensing of chromosome accompanied by splitting of the centrosome and its movement towards the opposite poles.

∙

As the nuclear envelope and nucleolus disappear, spindle fibres arise from the centrosomes and start binding to the condensed chromosomes at the centromeres.

∙

The chromosomes bound by the spindle fibers are then arranged in the middle of the cell forming the equatorial metaphase plate.

∙

Next the centromere splits and the sister chromatids are pulled away towards the poles by the contraction of spindle fibres.

∙

Following this, a cleavage furrow starts to develop in the middle of the cell while the nuclear membrane starts to reappear around the separated chromatids.

∙

The condensed chromatids start thinning into chromatin fibre along with reappearance of the nucleolus and the cleavage furrow deepening further.

∙

Finally as the nuclear membrane becomes fully intact, the cleavage furrow deepens and split the cells from middle into two daughter cells.

The picture shows one cause of the erosion of the Earth's surface. It is called A) agriculture. B) conservation. C) deforestatio

Inessa05 [86]

That would be C. Deforestation. Tree and plant roots keep the soil in place, when they are removed, there is nothing stopping the soil from blowing or washing away. Hope this helps!

Muscle contraction occurs in a cyclic process. Write down its sequence in the correct order?

Airida [17]

Options are not provided in the question. The complete question is:

Muscle contraction occurs in a cyclic process. Which of the following sequences is in the correct order?

A. power stroke, cross bridge formation, cross bridge dissociation, cocking of myosin

B. cross bridge formation, power stroke, cross bridge dissociation, cocking of myosin

C. cross bridge formation, cross bridge dissociation, cocking of myosin, power stroke

D. cross bridge formation, power stroke, cross bridge dissociation, power stroke, cocking of myosin

E. cross bridge formation, cocking of myosin, power stroke, cross bridge dissociation

Answer: B. cross bridge formation, power stroke, cross bridge dissociation, cocking of myosin

Explanation:

Muscle contraction is the activation of sites that produce stress within the muscle fibres.

The process of contraction begins with the Calcium ions that bind to the protein complex troponin and reveal the active-binding actin sites. The high-energy myosin head fills the gap, creating a cross-bridge, until the actin-binding sites are exposed. The filaments shift roughly 10 nm towards the M line as the actin is removed which leads to power stroke because it is the phase at which force is generated. Then teh ATP binds to the myosin and allows the bridge between actin-myosin dissociate. So soon so myosin attaches to actin, myosin's cocked head releases the actin fibre to slide. The cross-bridge generates energy, and actin displaces the myosin cross-bridge reaction products (ADP and Pi). This allows the process of contraction.

Hence, the correct order is B.
