<h3>Answer:</h3>

Unlike almost all ferns, seed plants  <u>create two varieties of spores.</u>

<h3>Explanation:</h3>

In biology, a spore is a part of sexual or asexual replication that may be accommodated for dispersal and for endurance, oftentimes for long duration of time, in adverse situations. Spores develop component of the life periods of various plants, algae, mildew and protozoa. Bacterial spores are not component of a reproductive cycle but are repellent compositions used for endurance following adverse situations. Myxozoan spores loose amoebulae into their hostesses for parasitic virus, but also generate within the hostesses by the pairing of two nuclei inside the plasmodium, which originates from specific amoebula.

Fossils show that ancestors of the giraffe had shorter necks than the modern giraffe. The evolution of the modern giraffe may be
MaRussiya [10]

Answer:

B. Directional selection

Explanation:

When natural selection starts to choose one phenotypes that is an extreme (as in, a really small neck or a really long neck), this is an example of <u>directional selection.</u> It makes sense for giraffes to have evolved this way, because the longer the neck, the more ably they can eat food from high branches. The more food they could get, the more chance of reproduction, the more "evolutionarily fit" they are.

Stabilizing selection is when national selection picks average phenotypes (like a medium-sized neck). Disruptive selection is when the extremes are both picked (like all the medium-sized neck giraffes die, and two different species start to emerge). Sexual selection is picking a mate based on traits. Clearly, those answers don't work here.

Summarize what the researchers did to improve the quality of post mining site soil
Salsk061 [2.6K]

Answer:

The researcher centred on the potential uses of biochar, charcoal primarily used for agricultural and to improve the quality of post mining sites.

A method called mountaintop removal was used by mining firms. This means that they remove rock and mineral deposits off the top of the mountain to gain access to within the coal seams. The resulting soil is infertile and strongly acidic. The compacted soil after mine proves harder to  bring seed into the soil.

The researchers  try to use biochar to help reforest the soil at the post-mining site. Before it was reseeded and replanted, they got permission to add a layer of biochar to a post-mining site. the team created “planting cells” of biochar‐enhanced soil on the post‐mining site and that showed improvment in the sapling growth.

Which statement best describes a keystone species
professor190 [17]

The answer is D

One way to remember this is when you are building a bridge there is one piece right in the middle that keeps the whole thing from collapsing that is called the key-stone. If a keystone species goes extinct then the rest of the ecosystem will crumble around it.
