Biology
1 answer:
erastova [34]2 years ago
7 0

Penguins are the rarest commodity of Antarctica. The paths they follow, carved by thousands of tiny footsteps, lead to Antarctica's rarest commodity.

<u>Explanation:</u>

The treaty sets aside Antarctica as a logical protect, sets up opportunity of logical examination, and bans military movement on the landmass. The bargain was the primary arms control understanding built up during the Cold War.

There are no regions in Antarctica by the Antarctic Treaty so you can travel anyplace on the landmass. In any case, by a similar settlement, there are various rules that all guests are required to follow. For instance, to regard logical research.

1. What causes the autorhythmicity or action potentials of the nodal cells? a. A decrease in chloride permeability b. A gradual
Sveta_85 [38]

Answer:

The correct answer will be option-C

Explanation:

The rhythm of the heartbeat is controlled by the pacemaker of the heart called the sino-atrial node.

The SA node generates action potentials which trigger the contraction and relaxation of the atrium and ventricles. The membrane potential generation initiates by the depolarization of the cell membrane when the L type of Ca⁺² ions opens up and calcium ions enter the cell.

This depolarizes the cell until the potential threshold is reached which lies between the -40 and -30 mV.

Thus, Option-C is the correct answer.

What do scientists use to mark boundaries in the geologic time scale?
tekilochka [14]

Era is used to mark the boundaries of geological time scale by using radio carbon dating technique.

Explanation:

Geological time starts with Precambrian time.

Geologically, time is divided between the Precambrian era and present time into era.

The three eras are Paleozoic era, Triassic period and Cenozoic era.

Era is further divided into periods.

Scientists use radio carbon dating to study fossils and rock formation. With this study they were able to divide them in exact geological scale.

Geologic scale is the record of events in earth's history and evolution.

What is the main prerequisite for clearance at the G2 checkpoint?
Katena32 [7]

Answer:

The correct answer will be option-accurate and complete DNA replication.

Explanation:

The cell cycle of a cell is controlled by the internal checkpoints where the cell cycle halts until the favourable conditions appear. These checkpoints are G1 checkpoint, G2 checkpoint and M checkpoint.

The G2 checkpoint asses that the DNA replication has been completed, all the chromosomes have been replicated and the replicated DNA is not damaged. The cell cycle stops if the replicated DNA is found damaged.

Thus, option-accurate and complete DNA is the correct answer.
