during which 3 phases are chromosomes not visible
There are 3 phases in which chromosomes are not visible. They are interphase, cytokinesis, and telophase.
Interphase: A typical cell spends most of its time in this phase. It can be said that the cell remains metabolic phase of the cell, until when the cell obtains nutrients and metabolizes them, and then it grows along with replication of its DNA in preparation for mitosis, and then it does other normal cell functions.
Cytokinesis: It is the final step of cell division. During this phase in which the two daughter cells become physically separated.
Telophase: Telophase is the fifth phase of mitosis. It is the process that generally separates genetic material carried in the nucleus of a parent cell into two identical daughter cells. Telophase occurs when the replicated, paired chromosomes have been separated and they are pulled to opposite poles of the cell.

a) at intercellular clefts
b) ar fenestrations
c) across endothelial cell membrane
d) with the help of transport proteins
The bulk flow of fluids that occurs in capillary beds typically occurs across endothelial cell membranes. Therefore, option (c) is correct.
What is Fluids?
Fluids are substances that have the ability to flow and take the shape of their container. They include both liquids and gases, and are distinguished from solids by their ability to flow and deform in response to external forces.
Liquids are a type of fluid that have a definite volume but no definite shape, and they assume the shape of their container.
Gases are another type of fluid that have no definite shape or volume. They expand to fill their container and are compressible. Examples of gases include air, oxygen, and carbon dioxide.
Fluids play an important role in many biological processes, including blood flow in the circulatory system, digestion of food in the digestive system, and the movement of air in the respiratory system. The study of fluids is an important part of physics, engineering, and other sciences.
Bulk flow of fluids refers to the movement of large amounts of fluid and solutes across capillary walls. This process occurs primarily through a mechanism called filtration and reabsorption. Filtration occurs at the arterial end of the capillary bed, where blood pressure forces fluids and solutes out of the capillary and into the surrounding tissues. Reabsorption occurs at the venous end of the capillary bed, where fluid and solutes are taken back into the capillary from the surrounding tissues due to the osmotic pressure difference.

how is it possible for one species to produce many other species?
Natural selection offers a explanation for how the genetic characteristics of a species may change through time. This might lead to speciation, or the emergence of new, distinct species.
The species sometimes exists in two (or more) populations, and thus inhibits interbreeding between them. When maintained apart for a long enough time and exposed to a wide enough array of environmental conditions, each population takes its own distinct evolutionary path. New species are produced by speciation, which happens when an ancestor population splits into two or more genetically distinct descendant populations. The process of speciation involves the separation of groups from the original population and the emergence of genetic differences between the two groups.

These plants lack the vascular tissues (.e.), structural support to stand erect in air. C. There were no available nutrients in the soil d. There was less competition for space so they simply spread out flat.
Correct answer is B. Biologists hypothesized that the first land plants had a low, sprawling growth habit because the ancestors of land plants, green algae, lacked the structural support to stand erect in air.
Around 470 million years ago, during the Ordovician epoch, when life was rapidly diversifying, the first terrestrial plants evolved. They were shallow-rooted non-vascular plants like mosses and liverworts.
A major extinction occurred after around 35 million years, when ice sheets momentarily covered a large portion of the world. Nobody knew why carbon dioxide levels likely dropped significantly right before the ice came.
The liverworts and mosses, according to Tim Lenton of the University of Exeter in the UK and colleagues, are to blame.
