<span>When we are talking about biogeochemical cycles we are talking about the pathways by which a chemical substance moves through both the biosphere and the atmosphere. There are a number of cycles which come back to the starting point and which can be repeated. Moreover, the very term biogeochemical tells us that there are more than one factor involved. We have chemical, biological and geological factors at play. The circulation of chemical nutrients through the biological and physical world are known as biogeochemical cycles.</span>
Answer:
1) The general characteristics of kingdom plantae are as follows −. Multicellular organisms with walled and frequently vacuolated. Eukaryotic cells. Contain photosynthetic pigments which are present in plastids. They are autotrophic mode of nutrition. Plants are non-motile, live anchored to a substrate. Autotrophic
: All plants are autotrophic, making and producing their own food and nutrients, without needing others to provide it for them.
Multicellular
: All plants all multicellular, meaning they are composed of more than one cell, which is what makes them visible to our naked eyes.
Eukaryotic: All plants are eukaryotic, meaning their cells all contain a nucleus, which is one of the organelles of the cell surrounded in a cell membrane. four characteristics that distinguish land plants from charophyte algae.
2) Alternation of generations (w/ an associated trait of multicellular, dependent embryos), walled spores produced in sporangia, multicellular gametangia, and apical meristems. These are evolved traits of land plants. Not all plants have retained these traits.
Explanation:
I added explanations inside the answer. I hope it make sense.
<span>The only word that would need to be used is "because." No other word would need to accompany it in this sentence. The subordinate clause that comes after it gives more information about why the car lacks room, so nothing else is needed to modify the word "because."</span>
Answer:
A gene is a section of a double-stranded molecule known as DNA. This molecule is found within the nucleus of the cell, contained in threadlike structures called chromatin. The two strands form a double helix linked by a series of paired bases. The base adenine is always linked to thymine and the base cytosine is always linked to guanine.
