I don't think changing seasons can REMOVE CO2 from the air, but I do think instead it could add it to the air. It's a long process that involves several ecosystems and stuff. But, as the climate is getting warmer, ice caps are melting and within these ice caps... there are trapped bubbles of CO2 that are released ( I am not sure if this adds a lot of CO2 to the atmosphere, but I am sure that it does contribute to CO2 concentration).
In relation to your last statement... plant growth would actually reduce CO2 in the air because of the process of photosynthesis. Plants take in CO2 and give out O2 for us to breathe. In turn we conduct cellular respiration in which we take in the O2 and give out the CO2. So, plants are actually one good solution for decreasing CO2 levels.
Answer:
b. During replication there is both a leading strand and a lagging strand
.
c. Each replication bubble has two replication forks.
Explanation:
Eukaryotic chromosomes have multiple origins of replication to replicate the long chromosomes at a higher rate.
The two DNA strands have opposite polarity, that is, 5' end of the one DNA strand is present opposite to the 3' end of the other DNA strand. DNA replication occurs only in 5' to 3' direction and the direction of the movement of the replication fork is also 5' to 3' direction.
To allow the DNA replication in 5' to 3' direction on both strands, one strand is replicated discontinuously in the direction opposite to the movement of the replication fork.
The discontinuously replicated strand is lagging strand while the other one is the leading strand.
DNA replication in eukaryotes occurs bidirectionally as two replication forks are formed at each replication bubble, one at each end of the replication bubble.
The presence of multiple origins of replication and the bidirectional process allows the replication of large eukaryotic DNA at a considerable fast speed.
<h3><u>Answer;</u></h3>
Morphology
The taxon species may be defined by <em><u>reproductive isolation and morphology </u></em>
<h3><u>Explanation;</u></h3>
- <em><u>A taxon is a group of one or more populations of an organism. </u></em>
- <em><u>Morphology is the form or the appearance of a particular organism, </u></em>while <u><em>reproductive isolation is the separation of organisms by some type of barrier.</em></u>
- <em><u>Reproductive isolation is a type of mechanisms that prevent two or more organisms or populations from exchanging genes through reproduction. </u></em>This occurs when two organisms or species are separated for too long such that they can no longer reproduce with each other due to different adaptation and changes in the environment.
- <u><em>Morphology and reproduction isolation may be defining characteristics of taxon of species.</em></u>
Answer:
Determining Chemical Properties using the Periodic Table. Chemical properties of each element are determined by the element's electronic configuration, and particularly by its outermost valence electrons.
Answer: D. adaptations that organisms make to the environment during their lifetimes.
Adaptation is a process in which changes occurs in an organism so as to make it better suited for the environment. It is the result of natural selection. In adaptation the traits of an organism gets modified by the process of natural selection which results in evolution of an organism.
