<span>The distance between the beginning of the first P wave and the first S wave tells you how many seconds the waves are apart. This number will be used to tell you how far your seismograph is from the epicenter of the earthquake. Measure the distance between the first P wave and the first S wave.</span>
Answer:
The correct answer will be- Keystone species
Explanation:
The structure of a community is largely determined by the number of species present in the community called species richness and the species diversity.
The species which can play an important role in determining the community could be of two types the foundation species and keystone species.
The species which directly influence the diversity of a community irrespective of their number and abundance is known as the keystone species.
In the given question since the question has discussed the species which disproportionately influence the diversity of the community is known as keystone species.
Thus, keystone species is the correct answer.
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:
SsBB and SsBB
or
SsBB and SsBb
Explanation:
To produce a ratio of offspring where the number of short haired black offspring is three times that of the long haired black offspring. Since, the long haired offspring can only be inherited in the recessive manner in two copies, thus possible genotypes of the parents could be:
SsBB and SsBB
or
SsBB and SsBb
SsBB and SsBB
SB sB
SB SSBB SsBB
sB SsBB ssBB
3/4 short haired black offspring and 1/4 long haired black offspring
SsBB and SsBb
SB Sb sB sb
SB SSBB SSBb SsBB SsBb
sB SsBB SsBb ssBB ssBb
6/8=3/4 short haired black offspring and 2/4=1/4 long haired black offspring
