Why do different biomes have different characteristic organisms?

Lady bird [3.3K]

Because the different environments permit some organisms to thrive, while others cannot. ... Similarly, a fish (extremely suited to its aquatic environment) can't survive out of water. A characteristic which allows growth in one environment will not necessarily allow growth in another.

inn [45]

The term "pneumocephalus" refers to the condition in which air is present in the cranial cavity.

What happens in pneumocephalus?

Increased intracranial pressure causes tension pneumocephalus, a neurosurgical emergency that can cause headaches, seizures, loss of consciousness, and even death.
Clinically separating the two entities is difficult but essential.
Tension pneumocephalus following skull base surgery was found to be a rare phenomenon with just eleven cases described, according to a survey of the literature on PubMed/MEDLINE.
After treatment, the majority of patients experienced full symptom relief.
Following skull base surgery, tension pneumocephalus is a potential complication that clinicians should be aware of.
An understanding of imaging characteristics and a high level of suspicion are necessary for accurate diagnosis. Rapid management is essential to avoid potentially disastrous effects.

Which is a function of a plants leaves?

Over [174]

Answer:

See Below.

Explanation:

The main function of the plants leaves is to create it's own food source via photosynthesis which produces glucose as one of it's products. Transpiration also occurs in the plant leaves where water evaporates out of the leaf increasing the concentration gradient, allowing more water to move up via the xylem via a column of water.

Most black bears (Ursus americanus) are black or brown in color. However, occasional white bears of this species appear in some

Sphinxa [80]

Answer and Explanation:

The number of observed individuals:

AA 42

AG 24

GG 21

Total number of individuals, N= 87 = 42 + 24 + 21

Allelic frequencies:

f(p) = (2 x AA + AG)/ 2 x N

f (p)= (2 x 42 + 24) /2 x 87

f (p) = (84 + 24) / 174

f (p)= 108 / 174

f (p) = 0.62

f (q) = (2 x GG + AG)/2 x N

f (q) = (2 x 21 + 24 )/2 x 87

f (q) = (42 + 24)/ 174

f (q) = 66/174

f (q) = 0.38

p + q = 1

0.62 + 0.38 = 1

The expected genotypic frequency:

F (AA)= 0.62 ² = 0.3844

F (AG) = 2 x A x G = 2 x 0.62 x 0.38 = 0.4712

F (GG) = 0.38 ² = 0.1444

AA + AG + GG = 0.3844 + 0.4712 + 0.1444 = 1

The number of expected individuals:

AA= (0.62)² x 87 = 0.3844 x 87 = 33.44

AG= (0.4712) x 87 = 40.99

GG= (0.38)² x 87 = 12.563

Total number of expected individuals = 33.44 + 40.99 + 12.563 = 87

Chi square= sum (O-E)²/E

AA= (O-E)² /E

AA=(42 - 33.44) ² / 33.44

AA= 2.2

AB= (O-E)² /E

AB= (24 - 40.99)²/ 40.99

AB=7.04

BB=(O-E)² /E

BB= (21-12.563)²/12.563

BB= 5.66

Chi square= sum ((O-E)²/E) = 2.2 + 7.04 + 5.66 = 14.9

Degrees of freedom = genotypes - alleles = 3 - 1 = 2

p value less than 0.05

There is enough evidence to reject the nule hypothesis. The genotype frequencies are not in equilibrium.

What is an example of a relationship between organisms in which an organism produces energy that is used by another organism to

agasfer [191]

Answer:

Tree frogs use plants as protection. Golden jackals, once they have been expelled from a pack, will trail a tiger to feed on the remains of its kills. Goby fish live on other sea animals, changing color to blend in with the host, thus gaining protection from predators.
