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.
Answer:
D
Explanation:
1. As given, the overall genome contain 50% G+C.
And the concept is that G is always pairs with C.
and A is always pairs with T.
So, in a dsDNA, A+G= T+C
2. As there that, there is a cluster of genes comprising about 20,000 bp that is 64% G + C so this so that the 20,000 bp segment is a recent acquisition via horizontal gene transfer.
Based on the image, it seems that the picture is of the layers of the atmosphere. Now the B layer is the thermosphere. It is found in between the mesosphere (layer below) and the ionosphere (layer above). It extends up to 600 km high and you can find satellites and the aurora here. Temperature here is higher as the height increases and it is because of this trait, its name thermosphere was based on on. "Thermo," in Greek means heat. It overlaps with the ionosphere.
Answer:
Aerobic respiration needs oxygen to occur, while anaerobic does not.
Explanation:
This presence of oxygen determines what products will be created. During aerobic respiration, carbon dioxide, water, and ATP are produced. During anaerobic respiration, lactic acid, ethanol, and ATP are created.
Intestinal parasites cause significant morbidity and mortality. Diseases caused by Enterobius vermicularis, Giardia lamblia, Ancylostoma duodenale, Necator americanus, and Entamoeba histolytica occur in the United States. ... A. duodenale and N. americanus are hookworms that cause blood loss, anemia, pica, and wasting.
