A horseshoe crab has been around for almost 500 million years. They are classified as arthropods and not actual crabs. However, There are many reasons that have helped them survive this long including, they can eat almost any organic matter. There blood is different from normal, in fact it’s blue. This blood helps them heal any wounds right away. They can also live in areas with very low levels of oxygen, meaning habitat is not a big issue for them. Evolution has also helped them grow and adapt seeing as they’ve survived this long.
Hope that helps:)
The three ways that heat is transferred are as follows:
Conduction, convection, and radiation.
Radiation is when heat is transferred in waves. It is the only type of transfer that can occur in a vacuum, so that is how heat reaches earth from the sun.
Conduction is when heat is transferred between solid objects. That is how heat is transferred between objects on the earths surface.
Convetsion is when heat is transferred through a liquid. This is how the ocean heats all the way through, rather than just the surface.

Answer:
Venus flytrap communicate with other organisms by secreting a sugary substance (nectar) in its leaf glands.
Explanation:
The Venus flytrap is a carnivorous plant that traps insects in a plant structure that closes when the small hairs on the inside of the structure are touched.
The leaf of this plant contains a watery fluid secreted by glands on its open traps. Organisms like flies are attracted to the secreted nectar and perches on it; only for the hairs of the flytrap to get shut due to that touch and cell expansion triggered.
