2020年4月29日 · There are different types of tissues in the human body; other animals and plants have tissues too but theirs will be described in another article. Four Major Types of Tissues in Human Body. Epithelial Tissue; Connective tissue; Nervous tissue; Muscular tissue; The 4 tissues mentioned above are the main types of tissues in the body.

2021年11月25日 · Xylem and phloem are the two main transport tissues of vascular tissues. They both carry out the transportation process in plants. However, the contrast of the xylem and phloem can be seen in their movement and function. In the phloem of plants, movement is bidirectional while movement is unidirectional in the xylem of plants.

2022年5月28日 · The vegetative and reproductive plant structures are treated in plant morphology. In fact, in vascular plants, the vegetative (somatic) structures include 2 main organ systems. Namely; Shoot system comprising of stems and leaves. Root system; These systems are similar in almost all vascular plants. Hence they provide a goal for plant morphology ...

2021年7月29日 · Furthermore, other fat-soluble (lipid-soluble) poisons are DDT and tetraethyllead compounds (the lead in leaded petrol). These chemical compounds are stored in the body’s fat tissues. Hence, these compounds are released when the fatty tissues are used for energy, causing acute poisoning. Bioaccumulation vs Biomagnification

2022年3月22日 · Humans and some animals as examples of multicellular organisms have four different types of basic tissues namely; Connective tissues, muscle tissue, epithelial tissues, and nervous tissue . The connective tissues e.g bone tissue are composed of fibrous cells and thus give shape and structure to organs.

2021年8月7日 · These organisms occupy trophic level 4 and get energy from other carnivores. However, they can also be preyed upon and organisms that feed on tertiary consumers are called quaternary consumers. The tertiary consumers and the quaternary consumers can respectively occupy trophic level-4 and 5. A typical example of a tertiary consumer is the Owl ...

2020年4月29日 · Sometimes, the Areolar connective tissue is also known as loose connective tissue because when viewed under low magnification with a microscope, it is found to be made up mainly of bundles of loosely arranged fibers that appear to enclose large spaces called Areolae and it is the commonest type of loose connective; however, there are other ...

2020年4月29日 · A branching enzyme (also called Amylo-1,4 1,6 transglycosylase) then brings about 1:6 linkages between UDPG molecules, resulting in the formation of branched glycogen molecules. When at least 11 residues of glucose have been added, the branching enzyme then breaks off a chain of about seven glucose units and rejoins them to a free 6-OH group as ...

2021年7月31日 · The wood frog, for example, survives winter by producing excess sugars. It converts glycogen into glucose which protects the tissues and cells of the animal cells even though most of the water in the body of the frog may freeze. Likewise, ray-finned fishes in polar marine environments possess high internal salt concentrations.

2021年8月26日 · However, biomagnification is the concentration of a chemical or toxin in the tissues of organisms at successively higher trophic levels in a food chain. This increase of the toxic substance at higher trophic levels could result from the substance being persistent in the environment, food chain energetics, and a low or non-existent rate of ...
