Biology
1 answer:
kkurt [141]3 years ago
3 0

<span>The answer is shared an evolutionary history. Homologous structures evolved from the same ancestor structure. An example of homologous features is the four limbs of all tetrapods. In birds, the forelimbs evolved into wings while in crocodiles they still used for walking, and in humans, they evolved into hands. </span>

A large-mouth bass is taken from a fresh water lake and transplanted into the river. If the conditions for survival are optimal,
liberstina [14]
The cells will make some sort of reaction, there's no doubt about it. But for a bass I believe that their cells will stay the same or shrink over time.
Bass are strong fish and they usually do well when there's a change in conditions made in the environment. But it depends on what this river has in it and if it leads to bigger opened waters.
If there's a shortage of food sources for the bass it'll have to adapt quickly or it'll die from the predators in the area. If there isn't any places the Bass can lay their eggs (reproduce) its population will die in that river.
There also competition. In that river it could have socked eye salmon in it or catfish even pikes. So the Bass cells would stay the same.

Hope this helps

Question involving the equations for Hardy Weinberg equilibrium (A^2+2Aa+a^2=1, A+a=1)
Alinara [238K]

Answer:

Frequency of dominant allele is 0.9029

Explanation:

Total number of organisms = 12,845

Number of organisms representing dominant trait = 11,596. These organisms might have heterozygotes with one dominant allele and one recessive allele.

Hence, Number of organisms with recessive alleles = 12845 – 11596 = 1249

Frequency of recessive allele (q) = 1249/12845 = 0.0971

Frequency of dominant allele (p) = 1- q = 1-  0.0971 = 0.9029

Species richness increases Select one: a. as we increase in altitude in equatorial mountains. b. as community size decreases. c.
olga55 [171]

Answer:

D) as we travel southward from the North Pole.

Explanation:

Species richness is the number of different species in a particular community. If we found 30 species in one community, and 300 species in another, the second community would have much higher species richness than the first.

Communities with the highest species richness tend to be found in areas near the equator, which have lots of solar energy (supporting high primary productivity), warm temperatures, large amounts of rainfall, and little seasonal change. Communities with the lowest species richness lie near the poles, which get less solar energy and are colder, drier, and less amenable to life. This pattern is illustrated below for mammalian species richness (species richness calculated only for mammal species, not for all species). Many other factors in addition to latitude can also affect a community's species-richness.

"what is total volume of the gas-exchanging region of the lungs?"
MrMuchimi
The total volume of the gas-exchanging region in the lung is called alveolar volume.

The alveolus is an air sack-like organ in the end of the respiratory airway. The alveolus is the site where gas-exchanging happens, so only air inside alveolus that will undergo actual exchange. Air in bronchus or trachea wouldn't do exchange
