The human skin is the protective layer of the human body against the external forces like the temperature, sharp objects, microbes, fungi and other related materials that can penetrate and weaken the body however, the integumentary system prevents any harm come to the organism. The dermis is the skin area which has different structures that perform different functions.
Answer: The tuatara is a lizard-like reptile found only in New Zealand today, the last surviving lineage of a large group of reptiles that were contemporaries of the dinosaurs.
The traits that would i expect the <u>tuatara</u> to possess are:
- Spiny back similar to that of dinosaurs.
- A well developed pineal eye.
- It lacks a copulatory organ.
- Spine-like vertebrae with intercenters.
- Anterior teeth, large and very sharp.
Explanation:
<u>Living fossil</u> is an expression used to qualify non-extinct species that are extremely similar to species identified only through fossils.
A <em>pineal eye</em> is a part of the epithalamus present in some animal species. The eye can be a photoreceptor and is commonly associated with the pineal gland, regulating the circadian rhythm and hormonal production for thermoregulation. The tuatara has a developed parietal eye, <u>with retina and lens.</u>
Answer:
This is an example of directional selection.
Explanation:
Directional selection is a type of positive selection where the evolutionary fitness of one genotype is higher compared to the other ones, thereby favoring the selection of one particular phenotype and shifting allele frequencies towards the selected genotype. In a biological context, the directional selection increases the chances for surviving and for reproducing in those organisms that have the alleles favored by this type of selection. Thus, the directional selection produces the loss of genetic variability and leads to the fixation of the dominant alleles.
Answer:
winter or fall
Explanation:
the northern hemisphere is pointing farther away from the Sun then the southern hemisphere
<h2>Favorable forward reaction </h2>
Explanation:
- The very favorable forward reaction means that the reverse reaction is very unfavorable
- This strong forward reaction driving energy effectively inhibits the depolymerization reaction DNAn + pyrophosphate → dNTP + DNAn-1
- A response that both absorb heat and decreases entropy will be non-unconstrained (positive ∆G) at all temperatures. A few responses, in any case, have a blend of ideal and horrible properties (discharging heat yet diminishing entropy, or retaining heat yet expanding entropy). The ∆G and suddenness of these responses will rely upon the temperature
