Why do water molecules "stick together"?
Answer:
Water molecules tend to stick together due to the structure and charge of the atoms present in the water. Hydrogen atoms are positively charged while oxygen atoms are negatively charged. ... All water molecules are exerting cohesive forces on all the molecules around them including those on the surface of a body of water
Explain briefly four
why, peasant
farmers find it diffcult to get
farm credit
Answer:
The peasant farmers operate mainly in the rural environment of the country. They operate on very small holdings using mostly traditional method because, their income is relatively low and the capacity to save is poor. Therefore needs for credit in order to meet the small farmers output and input

what is variable motion?Explain with example.
Answer:
Variable Motion. different distances traveled in equal times. The speed of the object is changing. Periodic Motion.
Explanation:
Explanation:
variable motion occurs when a body covers unequal distances in equal intervals of time in a specified direction. Example: A rotating fan at a constant speed has variable velocity, because of continuous change in direction.
The evolutionary history and development of whales has been hotly debated. Recently there has been a major shift in our understanding of the processes used to detail whale evolution. This indicates that: Group of answer choices A) Aspects of evolution are constantly being challenged and explored in light of new evidence. B) Gaps in the fossil records will never allow us to fully understand evolution. C) Scientists studying evolution typically present ideas with very little evidence, leaving it to others to find proof of their ideas. D) Much of the science of evolution is based on speculation that can easily be changed when scientists think of new ideas.
Answer:
Aspects of evolution are constantly being challenged and explored in light of new evidence
Explanation:
The whole idea of evolution has to do with the fact that organisms developed into their present form from simpler life forms. According to Oxford dictionary, evolution is; ''the process by which different kinds of living organism are believed to have developed from earlier forms during the history of the earth.''
Evolution depends on evidence from fossil records. Evidences that support the theory of evolution continue to be amassed as science advances. Hence, aspects of evolution are constantly being challenged and explored in light of new evidence.
For this reason, the evolutionary history and development of whales is being hotly debated and there has recently been a major shift in our understanding of the processes used to detail whale evolution.
write parasitic adaption of flat worm
Answer:
Parasitic flatworms protect themselves from the host's digestive liquids by developing teguments or resistant coverings around their bodies. They secrete anti enzymes to neutralize the digestive juices of host which are produced in intestine where flatworm lives.

What is "Radioactive Dating"?
A. A method of determining the age of a fossil that estimates the age of the organism at its death
B. A method of determining the age of a fossil based on the amount of certain isotopes that remain in a fossil or rock
C. A method of determining the age of a fossil that estimates how closely related various fossilized organisms were
D. A method of determining the age of fossil based on a comparison to the age of other similar fossils
Answer:
Unlike relative dating methods, absolute dating methods provide chronological estimates of the age of certain geological materials associated with fossils, and even direct age measurements of the fossil material itself.

The behavior of allosteric enzymes a. does not play any role in feedback inhibition in metabolic pathways b. is strongly dependent on the presence of metal ions c. is related to their ability to hydrolyze themselves d. depends on changes in their quaternary structure on binding of substrates or inhibitors
Answer:
The correct answer is d
Explanation:
Allosteric enzymes have multiple binding sites to different ligands called allosteric sites (different from the active site), these ligands can modify their kinetic properties. They are generally made up of more than one polypeptide chain, and have a quaternary structure, an enzyme with a quaternary structure can bind more than one substrate molecule. An allosteric enzyme is an enzyme whose activity is regulated by an allosteric center, which is a site, other than the active center of the enzyme, to which a regulator (called an allosteric regulator) binds in a reversible and non-covalent manner. The binding of this regulator modifies the three-dimensional structure of the enzyme and affects the configuration of the active site, thus increasing or decreasing its activity, depending on the case. The allosteric sites present in regulatory enzymes is where allosteric effectors or inhibitors are attached, causing a conformational change in the substrate binding site or catalytic site, thus regulating enzyme activity.
Answer:
d. depends on changes in their quaternary structure on binding of substrates or inhibitors
Explanation:
Allosteric enzymes are oligomeric proteins composed of subunits or polypeptidic chains. They have a quaternary structure -many subunits and active sites- and express two states, R and T. Both states establish an equilibrium, with or without a joint ligand.
When the transition from one state to the other occurs, symmetry is conserved, but the affinity of a site to a ligand is altered. When a substrate joins one of the sites, it affects other binding sites.
Allosteric enzymes can change their conformation, exhibiting active and inactive conformations as a result of substrate binding at the activated center and regulatory molecules at other binding sites -allosteric centers-.
