why do lichens and mosses get mostly replaced by larger plant species during succession

Answers

Answer:

Lichens that colonize bare rock secrete acids that break down the rock and start the soil-production process. Also, as lichens die, they provide some organic matter that also contributes to soil. Mosses can then colonize the thin soil; as mosses die, the soil thickens more allowing other hardy species to colonize

The oak and the maple are two different species of trees that also belong to different genera. However, these oak and maples do share many characteristics. Based on their similarities, which levels of classification would they share?

Answers

Answer:

Maple and oak trees are both deciduous angiosperms, so the wood each produces is classified as a hardwood. However, the difference between maple and oak wood is significant, and it would be difficult to mistake one for the other. All species of oak display a distinctive well-defined grain pattern whereas the maple wood grain tends to be creamy white with little visible grain. The differences don't stop there, but to really appreciate them, it's important to realize that within the broad category defined by oak is a subset of species that differ significantly from each other. The same is true for maple

Answers

Walking upright.

You can make a case for all of them, but for three of them indirectly.

But the answer, I think, is walking upright.


You can look at the pelvic bones and femur orientation in the hips. You can also look at the way the skull sits on the vertebra.

Chimpanzees have a skull that sits more downward, because they walk on all fours most of the time. While humans have skulls that sit more horizontally on the vertebra, which allows us to see out on the horizon more easily. We can do that because we stand on two feet.

Recombinant DNA technology is possible because all organisms
O A. rely on ribosomes to assemble proteins
B. have some of the same genes
C. use the same codes for amino acids
D. replicate DNA before cell division

Answers

Recombinant DNA is possible because all organisms use the same codes for amino acids. Option C is the correct one.

The genetic codes

One of the fundamental characteristics of the genetic codes is that they are similar in all living organisms.

Each genetic code is translated into an amino acid. Thus, living organisms use the same codes for their amino acids in the proteins.

This makes inserting the genes of one organism into the genome of another (recombinant DNA) very easy.

A base pair (bp) is the pairing of two nucleobases located on two complementary strands of DNA or RNA. This pairing is carried out by hydrogen bridges. There are four types of nucleic bases: A-T-C-G, these letters Adenine, Thymine, Cytosine, and Guanine. A with T and C with G.

It is also necessary to take into account the antiparallel character of the DNA strands. If a strand is in the 5 '3' direction, its complete strand is in the 3 '5' direction.

Explanation:

The system of checks and balances refers to instances in which the powers of the branches of government overlap, such as the Executive and the Legislative branch both having some power over the acts passed by Congress. Separation of Powers refers to instances in which separate branches have completely separate responsibilities, as in creating, interpreting, and enforcing the laws. Both of these doctrines are in place to ensure no branch gains too much power.
