Answer:
Types of tissues:-
Nervous tissue, Epithelial tissue, Muscle tissue, and Connective tissue.
Explanation:
Nervous tissue is made up of nerve cells (neurons) and is used to carry "messages" to and from various parts of the body.
Examples are cells, neurons and glial cells.
Muscle tissue includes striated (also called voluntary) muscles that move the skeleton, and smooth muscle, such as the muscles that surround the stomach.
Examples are blood vessels, biceps and intestines.
Epithelial tissue provides a covering (skin, the linings of the various passages inside the body).
An example is the epidermis, the outermost layer of the skin and outerlayers on internal organs.
Connective tissue supports other tissues and binds them together (bone, blood, and lymph tissues).
Examples include adipose, cartilage, bone, blood, and lymph.

Answer:
The <u>biological species concept</u> is not very useful in defining plant species.
Explanation:
The biological species concept says that <em>species are population groups that, in a real or potential way, can reproduce and that </em><em>are reproductively isolated from other groups.</em>
<em>Individuals belonging to a species cannot reproduce with members of other species. </em>
This biological concept has limitations. Its application might present difficulties in concern with asexual reproduction species, such as bacteria, rotifer, cnidarians, plants, and etcetera.
Besides, this concept cannot be applied to the past because it is difficult to deduce reproductive capability between extinct species.
Finally, this concept is not adequate in concern to hybridization zones, something to be expected considering evolutionary processes. This is why this concept has been less accepted by botanists, as some plant species hybridize with other species. For example, species Quercus grisea and Quercus gambelii have overlapping ranges in the southwestern United States. Hybrids showing variation in leaf shape and other traits have been found in many places in this area.
The corpus callosum, a tight region of axons (whitematter), is the direct connection and thus communication between left and right hemispheres.
A "split-brain" could result from disruption of or damage to the corpus callosum, either in part or whole.
<span>Before answering the question, some explanation about the purpose of flow cytometry.
The cytometry analysis provides us with the presence and the abundance of </span><span>clusters of differentiation (CD), for example, the research of CD2, CD3 and CD4 in lymphocytes.
</span>These CDs will be marked (if they are present) with specific antibodies linked with different fluorochromes, and when the <span>cells exit the flow cell intersect, a laser detects these fluorochromes (representing CDs) and count them.
</span><span>The result will be displayed in a graph showing the frequency of the CDs with spots of different colours.
