Answer:

The correct answer will be- true, all the options are correct.

Explanation:

Cactus or the species of Opuntia genus are adapted to grow on the desert conditions or the area with no water or xerophytic conditions.

The leaves of the plants become modified to take the shape of the spines which provide many advantages like protection from herbivores and providing shape to the plant.

In the species of teddy bear cactus <em>(Opuntia bigelovii)</em>, the cactus serve a third purpose that is they help in the propagation of the species. The spines possess tiny barbs at the ends which help them attach to the animal or any object that walks by and the falls of somewhere else. The fall-off portion of the cactus grow roots and form a new cactus there.

Thus, true is the correct answer.

faltersainse [42]

Water drains into the sinkhole pollution due to factories

The lake was created as limestone gradually dissolved, causing the sediment layer above it to collapse and creating the lake basin. Low lake levels and slow draining can be caused by bottom leaks, sinkholes, and swallets, long-term dryness, and a lack of recent, strong rainfall events.

<h3>What causes lake Jackson to disappear ?</h3>

Before the lake dried up, those walking along the shore of the sinkhole at Lake Jackson on Thursday would have been in three to four feet of water.

  • Environmentalists refer to the process as a "dry down," and it occurs every ten or twenty years. The likelihood of causes includes dry weather, a lack of rain, and a decreased water table.

  • The lake will typically begin to fill again after the sinkhole plugs itself, sometimes taking years to do so pre sinkhole level

Why is a key bed used?
Anna11 [10]
In geology, a key bed (syn marker bed) is a relatively thin layer of sedimentary rock that is readily recognized on the basis of either its distinct physical characteristics or fossil content and can be mapped over a very large geographic area.[1] As a result, a key bed is useful for correlating sequences of sedimentary rocks over a large area. Typically, key beds were created as the result of either instantaneous events or (geologically speaking) very short episodes of the widespread deposition of a specific types of sediment. As the result, key beds often can be used for both mapping and correlating sedimentary rocks and dating them. Volcanic ash beds ( and bentonite beds) and impact spherule beds, and specific megaturbidites are types of key beds created by instantaneous events. The widespread accumulation of distinctive sediments over a geologically short period of time have created key beds in the form of peat beds, coal beds, shell beds, marine bands, black  in cyclothems, and oil shales. A well-known example of a key bed is the global layer of iridium-rich impact ejecta that marks the Cretaceous–Paleogene boundary (K–T boundary). Please let me know if it works.

When a peptide hormone reaches its target cell, which event happens next?
oksano4ka [1.4K]
<span> They are unable to pass through the plasma membrane and have different methods of action. They attach to their receptors in the target cell surface and influence activity within the cell through cytoplasmic intermediates called second messengers. </span>

<span>The two most important messengers are cAMP and inositol triphosphate. </span>

<span>Cyclic AMP: ATP is converted into cAMP after a series of reactions on the plasma membrane following the attachment of the hormone to the membrane. cAMP relays the signal from the membrane to the metabolic machinery of the cytoplasm. </span>

<span>Inositol Triphosphate: Involves the use of Ca+2 that regulates cellular protein activity.
</span>
