Answer:
Lycopodium which is an example of Club mosses are seedless vascular plants that are heterosporous.
Explanation:
The club mosses, or phylum Lycopodiophyta, are the earliest group of seedless vascular plants. They can either be homosporous or heterosporous
Some club mosses like Lycopodium clavatum, sporangia are arranged in clusters called strobili.
Lycopodium is heterosporous (while some club mosses are homosporus.
Heterosporus means that spores of two different sizes and sexes are produced by the sporophytes of land plants.
Explanation:
Scavenging refers to carnivores feeding on carrion.
Answer:
Hydrogen Bonds
Explanation:
In the polymerase chain reaction (PCR) the temperature rises to 90 ° C - 95 ° C, to break the hydrogen bonds, which are the types of bonds responsible for pairing the two strands of DNA, this process is known as denaturation of DNA.
The DNA is extremely stable, due to a large number of bonds (hydrogen bonds) that form between the two strands. If the temperature decreases, these bonds will begin to recompose, until the DNA returns to its original state
Passive is when the channels don't need energy to do so and active is when they need energy
Blood clots will do this. Cutting off blood flow while also increasing blood pressure. Also, if the viscosity (thickness of the blood) is thick which will slow down the flow and cause the body to use more effort to pump blood.
