Answer: Option B and C.
Heavy and continuous rains flood the land, submerging habitats.
c. Lightning strikes a tree and begins a fire that clears the land.
Explanation:
Heavy and continuous rains flood the land, submerging habitats.
Lightning strikes a tree and begins a fire that clears the land.
The above are example of density independent abiotic factors because rainfall and lightning affect the population size of the environment by decreasing it's population sizes.
Abiotic factors are the non living part of the environment and they include rain fail, temperature,lightning, humidity e.t.c.
Density independent abiotic factors are factors that decrease or increase the population size of the ecosystem.
Therefore, Heavy and continuous rains flood the land, submerging habitats.
cLightning strikes a tree and begins a fire that clears the land are density independent factor because they decrease the population size.
Evaporation occurs <span>when water absorbs 2260 Joules of heat energy per gram. It is </span><span>process by which water changes from a liquid to a gas or vapor.</span> It takes energy for the molecules to break those bonds (to overcome the bonding
forces). This energy is the latent heat of vaporization.

Water requires the addition of 2260 Joules of heat energy for every gram of water that evaporates (vaporizes). The heat energy that is required to change water into vapor is called the latent heat of vaporization.</span>
Answer:
The Archean Eon marked a time when Earth’s climate began to stabilize.
Earth cooled down from its molten state. It eventually could support oceans. Tectonic activity built continents.
In the Archean Eon, oxygen filled the atmosphere and most of the world’s iron ore was deposited.
Because the Earth’s conditions stabilized, eukaryotic and multicellular life could finally emerge in the Proterozoic Eon.
Explanation:
Answer:
increasing extension time
Explanation:
The Polymerase Chain Reaction is a technique widely used in molecular biology laboratories to amplify target DNA regions. The standard steps of a PCR are as follow 1-denaturation, 2-annealing and 3-elongation/extension. These steps are repeated 15-40 times in order to exponentially amplify the linear DNA fragment. It is well known that longer extension times can be used as a strategy to increase the yield of longer PCR products. This is because the extension time depends on the synthesis rate of the DNA polymerase used in PCR technique and the length of the DNA fragment to be amplified.
The answer would be: <span>dysfunction of spermatogenesis
</span><span>Follicle-stimulating hormone(FSH) is one of the hormones that was regulated by the anterior pituitary. FSH is secreted by the gonadotropic cells and it has roles in growth and development of sexual organs. FSH will promote maturation of ovarium in female and spermatogenesis in the male.</span>
