What is the principal negative ion (anion) in the extracellular fluid (ecf) that is present in high concentrations?
The principal negative ion i.e. anion that is present in the Extracellular fluid ( ecf ) in high concentrations is Chloride ( Cl ⁻ ) .
Chloride ion is a major contributor for the Osmotic Pressure gradient between the Intracellular Fluid ( ICF ) and Extra Cellular Fluid ( ECF ) . It plays a role of immense importance in maintaining proper hydration. Chloride also plays an important role to balance cations in the ECF, hence maintaining the electrical neutrality of this fluid.
Hypochloremia is a disease in which blood chloride levels are lower-than-normal . Hyperchloremia is a disease in which blood chloride levels are higher-than-normal blood chloride levels . It can occur due to dehydration, excessive intake of NaCl .

When the simple squamous lines the cardiovascular and lymphatic system, it is called:_________
When the simple squamous lines the cardiovascular and lymphatic system, it is called endothelium.
While epithelial cells line outer surfaces, endothelial cells line inner surfaces. Simple squamous endothelial are flat cells that line the inner surfaces of the heart, blood vessels and lymphatic system. They are continuous and form a barrier between the circulating blood or lymph and the walls of the vessels.
There are two types of endothelial cells - Vascular endothelial cells and Lymphatic endothelial cells. The vascular endothelial cells are constantly in contact with blood and line the inner surfaces of blood vessels, from the heart all the way to the tiniest capillary. Lymphatic endothelial cells can be found in the lymphatic system.
In the glomerulus of the kidney, endothelial cells are responsible for fluid filtration. They also help in blood clotting and formation of new blood vessels.

How many different compounds (isomers) are there that fit the description of a bromo-chlorobenzene?
The no. Of possible isomers for bromo-chloro benzene is 3.
Three possible isomers for bromo-chloro benzene is 1-bromo-2-chlorobenzene, 1-bromo-3-chlorobenzene & 1-bromo-4-chlorobenzene.
Isomers are identical molecules with different structural characteristics. As a result, although having the same number of atoms in each element, isomers have different atomic arrangements.
Even if all molecules have the same molecular formula, they may have various physical characteristics, especially if their respective functional groups are unique. Isomerization is the transformation of one molecule into another molecule with the same number of atoms. This could happen on its own or maybe a reaction is needed to make it happen.
Isomers are generally divided into two categories:-
Structural isomerism - have same molecular formula but different structural formula. Stereo isomerism - Have same molecular formula but different arrangement of atoms in 3d space.To learn more Stereo isomers, refer this link.

Why was motion of Earth not observable after the action-reaction event with the ping pong ball or clay ball?
According to Newton’s third law, motion of Earth is not observable because Earth is so large, we cannot perceive the change as it is so negligible.
Newton's third law of motion states that every action has a corresponding and opposing response.
The action-reaction forces can be used to study or observe Newton's third law. When a clay ball or ping pong ball is put to the ground, the clay ball flattens on the side that meets the ground while the ping pong ball rebounds into the air.
Newton's third law states that even though the action-reaction forces on the balls and the Earth were equal in strength and directed in opposing directions during each encounter, the resulting movements of the interacting objects were dependent on their masses.

Select the possible changes in e. coli that made them more resistant with each successive round of radiation and selection?
Mutation have made DNA repair more efficient
In a study published describe blasting E. coli bacteria with ionizing radiation one per week, caused the bacteria to become radiation resistant. In doing so, they have became genetic mutations and mechanisms underlying this resistance.with time , as the bacteria have become resistant, the researchers have been able to elevate the level of radiation to which they exposed the bacteria mutations . The study took a deep dive into the mutations they have collected after 50 cycles (meaning the bacteria were irradiated 50 times).While the total mechanisms, such as increased DNA repair, are the same as in naturally resistant bacteria, many of the mutations that caused those changes have never been seen before mutations . Bruckbauer added that beyond DNA repair and changes to RNA polymerase, there are whole new ways of being resistant that could arise.

Nonpolar covalent
Ionic
Hydrogen bonds
Polar covalent
Pls HELPPP
Answer:The electronegativity difference between F-Cl is 3.98 - 3.16 is 0.82. Therefore, in the F-I bond, the electronegativity difference is greatest.
Explanation:
In a diatomic molecule with two identical atoms, there is no difference in electronegativity, so the bond is nonpolar or pure covalent. When the electronegativity difference is very large, as is the case between metals and nonmetals, the bonding is characterized as ionic.Cesium fluoride has both the most electronegative atom and the least electronegative atom. Therefore, it must have the greatest difference in electronegativity between its atoms.

What characteristics of life are not independently demonstrated by viruses?
Because they are not formed of cells, viruses cannot maintain a steady state, develop, or generate their own energy. Viruses are more like robots than actual living things, even though they do multiply and adapt to their surroundings.
What aspects of life are exhibited by viruses?The ability to replicate and mutate are two aspects of life that viruses possess, but only in live host cells.
Viruses and bacteria differ greatly from one another. While viruses may grow in both living and nonliving environments, bacteria are found in nature. While viruses might perish without a host, bacteria can live without one. Viruses reproduce by lytic fission, whereas bacteria reproduce through binary fission.
Although they are minuscule as well, viruses are distinct from other microbes.
Viruses are intracellular creatures (they infect the host cell), whereas bacteria are intercellular organisms (they exist in between cells).

Which of the following is the process for removing waste from cells?
The process for removing waste from cells is called Exocytosis.
Exocytosis, often known as throwing out dangerous or waste material by cellular organelles, is the act of removing waste from the cell. This is accomplished by lysosomes, also known as secretory bags of cells.Basic Process of Exocytosis Vesicles containing molecules are transported from within the cell to the cell membrane. The vesicle membrane attaches to the cell membrane. Fusion of the vesicle membrane with the cell membrane releases the vesicle contents outside the cell.The only essential organs explicitly involved in the excretion process are the kidneys. While other organs involved in the body's waste removal are also crucial to other important processes.To know more about Exocytosis, visit:

simple explanation:
there are many things that animals or plants compete for:
animals:
mates-some animals my be desperate to pass on their genes to offsprings. also if there is a decrease of one sex of an species the other may find it difficult to find a mate and can end up fighting their counterparts
territory -lack of territory also causes competition
food -lack of food can cause competition
Plants:
space: some trees 'want' or require a large amount of space to survive because they are bigger and my want to collect more nutrients form soil and take more light
light/sunlight: plants require sunlight for : plants photosynthesis they may grow their leaves big for a big surface area to collect more light.
water/minerals in soil: plants need water to grow so they may grow their roots deep and long
The two causes of competition between two species are the habitat has only a limited quantity of resource both species need and the species do not have a way to partition a resource they both need. Thus, the correct options are c and d.
What is Competition between species?
Competition is a type of interaction between species which occurs when the two species require same resource that is available in limited amount. So, the availability of the resource to one species is negatively influenced by the presence of the other species which leads to competition and exclusion of one species from the environment.
Competition between two species occurs when both the species are using the same resources in an area. Competition is of two types interspecific and intraspecific competition. In competition, the species do not have a way to partition the resource they both need.

You cross a pure-breeding white flower with a pure-breeding red flower, and the offspring are white with red spots. what type of inheritance is this an example of?
If you cross a pure-breeding white flower with a pure-breeding red flower, and the offspring are white with red spots and as F1-hybrid plants have a different phenotype (pink flowers) than either of the true-breeding parents, thus, it is an example of incomplete or partial dominance.
Pure-breeding offspring with pink flowers (Rr) were produced via a genetic cross between a pure-breeding with red flowers (RR) and a pure-breeding with white flowers (rr). It demonstrates that the gene for red could not entirely suppress the gene for white.
The pink flowers on the F1 hybrid plants are a different phenotypic from either of the true breeding parents. This is an illustration of partial dominance.
