Evolutionary Theory of Aging describes t<span>he view that natural selection has not eliminated many harmful conditions and nonadaptive characteristics in older adults. N</span>atural selection is linked to reproductive fitness, which is present only in the earlier part of adulthood. According to evolutionary theory, possibly if some disease occurred earlier in development, it might have been eliminated many centuries ago.
Answer:
Arthropods make up almost 80% of all animals; they are jointed legged animals that belong to the Animalia kingdom that include centipedes, millipedes, insects, and spiders. The success of arthropods can mainly be attributed by the following characteristics;
Presence of Exoskeleton.
The presence of exoskeleton that hardens due to the presence of chitin offers a protective cover for arthropods with different environment against advance conditions and also it protects against dehydration.
Varied habitats.
Arthropods can be found in all types of habitats from the soil, water, and land. This feature is the key to their survival since they are widely distributed hence increasing chances of survival.
Bilateral Symmetry.
Arthropods exhibit bilateral symmetry whereby a different portion of their bodies are mirror images, this form is exhibited in higher animals such as humans and dogs, and it facilitates advanced body functioning.
Jointed Legs.
Arthropods exhibit segmented legs that are jointed to allow the development of hard exoskeleton for protection. The jointed legs are specialized for grasping, jumping and running.
Short generation time.
Arthropods exhibit short generation time, which allows for faster adaptation to the environment and survival.
Reproduction strategy.
Arthropods have exhibited a sexual form of reproduction that is more successful in the growth and survival of offspring.
Segmented body.
Arthropods have a segmented body that allows for specialization of body organs and tissues, and this has promoted their success by specializing body organs to different functions.
He developed and proposed a theory about evolution. Which is humans and animals changing to suit their environment over years
Answer:
I am 100% sure that the answer is (True).
Answer:
B) energy is captured in the bonds linking amino acids that compose lipase.
Explanation:
Anabolic reactions are chemically defined as synthesis reactions in opposition to Catabolic reactions, in which a degradation of chemical compounds occurs. Thus, in anabolic transformations simpler reagents are used to produce more complex substances. In the particular case of the synthesis of a lipase, a number of amino acids are chemically bonded to form a polymerized structure, clearly chemically more complex, known as polypeptide.
An increase in chemical complexity always requires an investment of energy, considering that building a larger molecule implies bonding more reagents or precursor into the final product. Thus, the increase in the energy content of the product (in this case the lipase) when comparing to each precursor (individuals amino acids) will be reflected in the linking (covalent) bonds between amino acids. Of course, there is always a certain amount of energy that is lost as heat during any chemical transformation (not all the energy invested in the synthesis will be captured in the product).
The overall of all anabolic reaction which take place inside the cell is called anabolism, while the whole set degradation chemical reaction occurring within the cell is known as catabolism. Being said that, it is clear that anabolism and catabolism, when being considered jointly, conform the metabolism as a whole and coordinated cellular process.
