Which of the following would be least likely to support the modern concept of biological evolution? ( 2 points) a)different species of organisms with similar bone patterns b)different species of organisms with similar reproductive rates species in c)different domains with similar metabolic pathways species in d)different kingdoms with similar cellular structures.
B. create and conserve body heat better.
Ectotherms are cold blooded animals, which depends on external heat sources like sunlight to maintain their internal body temperature. The ectotherms include fishes, reptiles, invertebrates and amphibians. They do not require as much as food consumed by the warm blooded animals. They are unable to tolerate cold surroundings. Endotherms are warm blooded animals. These animals generate heat in their body. They increase their heat metabolism with respect to cold surrounding to maintain their internal body temperature constant. These animals are not much dependent on external heat as ectotherms are.
Therefore, in contrast to ectotherms, endotherms create and conserve body heat better.
c species in different domains with similar metabolic pathways
biological evolution is defined as any genetic change in a population that is inherited over several generations. these changes may be small or large, noticeable or not so noticeable.this means that the genes, or more specifically, the alleles in the population change and are passed on.
answer; ///i believe that the correct answer is (e); check first good
I believe the correct answer is D. React to stimuli from outside the body.Explanation:
Hormones are types of proteins that produce responses hand in hand with neurons but they are much slower and longer lasting. They can act on the same cells and in that instance they will be called autocrine hormones. Those that act on neighbouring cells are called paracrine hormones while those that act on far away cells are called endocrine hormones.Further Explanation:a. Initiate behavior and reproduction:
This is a function of hormone(s). Hormones such as testosterone can initiate both behavior of an organism and also stimulate reproduction. Testosterone causes maturation of sex features and sperms in males to initiate reproduction. Other hormones with such functions include: Estrogen and adrenaline.b. Coordinate the production and use of energy:
Some hormones conduct this function by regulation metabolism in the body. These include: Insulin in intake of glucose for energy and glucagon in maintaining blood glucose levels. Corticosterone also responds in stress to maintain energy.c. Maintain nutrition and metabolism:
Nutrition can be maintained by hormones such as ghrelin that stimulates appetite, insulin in intake of glucose, leptin and glucagon.d. React to stimuli from outside the body
This is not a function of a hormone but rather the function of a neuron. Neurons have specific structures called denrites that recieve signals/stimuli from outside the body then convert them to nerve impulses that are transmitted to the brain which produces another impulse to be taken to a specific site to produce a desired response.

The correct answer is the option "The metabolic rate of the ectothermic organism would increase, and the metabolic rate of the endothermic organism would remain unchanged"
Let's solve this!
First we will define what ectothermia and endothermia means.
Ectothermic is a living being that regulates its temperature according to the external temperature.
Endothermic is a living being that regulates its internal temperature regardless of the ambient temperature.
After this analysis we will conclude that the correct answer is the option "The metabolic rate of the ectothermic organism would increase, and the metabolic rate of the endothermic organism would remain unchanged"
the correct answer to your question would be option a
The main parts of metabolism includes the two components which are: Catholicism, and Anabolism.
Endothermy is a physiological characteristics that enables some animals to control their body temperature unlike exothermics. This mechanism is important due to sudden change in temperature or uncontrollable conditions set by the harsh environment.
So birds sharks salamanders and other related animals have this function.
Endotherms produce their own heat, ectotherms rely on external heat sources.
