Biology

Vikentia [17]3 years ago

The best statement that describes lightning is A. It is one of the most dangerous parts of a thunderstorm. Lightning, although often thought to always strike the Earth, can actually occur in the same cloud (intracloud) and between clouds (cloud to cloud). It is caused by the electrostatic discharge between charged particles in the atmosphere.

Some present-day bacteria use a system of anaerobic respiration characterized by an electron transport chain analogous to that f
geniusboy [140]

Answer:

The correct answer would be:

Neither of these response options accurately features the anaerobic electron transport chain.

Explanation:

The anaerobic respiration system vibrated by an electron transport chain is a mechanism that anaerobic bacteria have to maintain their respiration.

This mechanism does not require oxygen in the atmosphere, that is why it is said to be an anaerobic mechanism.

Bacteria do not all need oxygen in the environment to live, some need that oxygen is not exactly present (strict anaerobes) or that it is at low partial pressures (facultative anaerobes).

This mechanism is very characteristic in its location since it is located in the inner membrane of the mitochondria, that is why it will decide to indicate that option as the correct one.

Hardy-Weinberg Principle

Genotype frequency equation

 p^{2} +2pq +  q^{2} = 1

Where p² is the freq of homo dominant genotype, 2pq is the freq of heterozygous genotype and q² is the freq of homo recessive genotype.

Allele frequency equation

p + q = 1

Where p is the frequency of dominant alleles and q is the frequency of recessive alleles.

Yellow eyes in the frog offspring is a phenotype (physical trait) that would be a expressed by a geneotype (YY or Yy). This frequency, 0.85 includes: p² + 2pq

0.85 + q² = 1

q² = 0.15

p = \sqrt{0.15} 

Then p + \sqrt{0.15}  = 1

1 - \sqrt{0.15} = p

p = 0.613

Mikayla says that air is an element since it has oxygen in it. Jose says that air is a mixture because each part of air keeps it
natka813 [3]
The answer is d, since air is a muxture of compounds. a way to differentiate between a muxture and a compound is to see it it is a word you would say normally. for example, you would say air on a normal day. however, you wouldn't say carbon monoxide on a normal day.
hope it helped! :)
