Answer:

The correct answer is - Nematocycst.

Explanation:

Nematocysts are aquatic animals that contain stinging cells known as cnidocytes. These organisms are members of the phylum Cnidaria. These carry a organelle called cnida or cnidocyst.

An example of such an organism is Jellyfish. Sting cells are specialized neural cells that release extensive Golgi secretion venom that causes a stinging experience to the prey the nematocyst.

What is TRUE about the North and South Poles? Select all that apply.
Romashka [77]

The poles never get any direct sunlight.

They both get the same amount of sunlight.

  • Because they receive no direct sunshine, the Arctic (North Pole) and Antarctic (South Pole) are both chilly.
  • Even at the height of summer, the Sun is low on the horizon. The Sun doesn't rise at all for several months during the winter since it is so deep below the horizon hence poles don't have equal amounts of sunlight and darkness.
  • The poles receive less energy and heat from the sun because of the tilt of the earth and its orbit around the sun. There are just two polar seasons as a result: summer and winter.
  • The tilt of the Earth's axis causes the Poles to experience around six months of day and six months of night.
  • Due to this tilt, each Pole spends roughly six months angled both toward and away from the Sun. The North Pole experiences six months of nonstop daylight when it is inclined toward the Sun.
  • In the winter, the Sun sets for extended periods of time since it is so deep below the horizon. Therefore, the days are chilly and dark, much like the nights. The South Pole and North Pole receive the same amount of sunshine despite being "polar opposites."

Describe the earth’s geography and atmosphere during this time period. What major events happened to help shape the earth during
Luba_88 [7]

The geological history of Earth follows the major events in Earth's past based on the geological time scale, a system of chronological measurement based on the study of the planet's rock layers (stratigraphy). Earth formed about 4.54 billion years ago by accretion from the solar nebula, a disk-shaped mass of dust and gas left over from the formation of the Sun, which also created the rest of the Solar System.

Earth was initially molten due to extreme volcanism and frequent collisions with other bodies. Eventually, the outer layer of the planet cooled to form a solid crust when water began accumulating in the atmosphere. The Moon formed soon afterwards, possibly as a result of the impact of a planetoid with the Earth. Outgassing and volcanic activity produced the primordial atmosphere. Condensing water vapor, augmented by ice delivered from comets, produced the oceans.

As the surface continually reshaped itself over hundreds of millions of years, continents formed and broke apart. They migrated across the surface, occasionally combining to form a supercontinent. Roughly 750 million years ago, the earliest-known supercontinent Rodinia, began to break apart. The continents later recombined to form Pannotia, 600 to 540 million years ago, then finally Pangaea, which broke apart 200 million years ago.

The present pattern of ice ages began about 40 million years ago, then intensified at the end of the Pliocene. The polar regions have since undergone repeated cycles of glaciation and thaw, repeating every 40,000–100,000 years. The last glacial period of the current ice age ended about 10,000 years ago

A is a speleothem that forms on the ceiling of a cavern and resembles an icicle made of rock.
Novay_Z [31]

Stalactite.

<u>Stalactite:</u>

  • Often, stalagmites develop up from the cave floor, whereas stalagmites typically grow down from the cave roof.
  • It's simple to distinguish between the two since stalagmites have a "G" for ground and stalactites have a "T" for top.
  • Typically made of calcium carbonate, stalagmites can also be made of lava, mud, peat, pitch, sand, sinter, and amber.
  • A single drop of water rich in minerals is the origin of all limestone stalactites.
  • The smallest ring of calcite is left behind by the falling water drop.
  • Another calcite ring is left behind with each new drop of water that develops and drops.
