Answer:

Ascending, Position, Touch, Somatosensory Pathways, Viscerosensory Pathways.

Explanation:

Sensory pathways are ascending pathways that conduct information about limb position, and the sensations of touch, temperature, pressure, and pain to the brain.

Stimuli received from receptors within the skin, muscles, and joints are processed through somatosensory pathways, while viscerosensory pathways process stimuli received from the organs.

I hope this answer helps.

What are the classification levels of humans for order, suborder, family, tribe, genus, and species? Group of answer choices Mam
Finger [1]

Answer: Human classification levels for order, suborder, family, tribe, genus and species are;

Primates, Primates, Haplorhini, Hominidae, Hominini, Homo, and sapiens , Hominidae, Hominini, Homo, and sapiens

Explanation:

Human taxonomy is the systematic classification of humans.

The order is primates include placenta animals including humans, that have good eyesight, flexible hands and feet, well developed brain and they include man, lemurs, apes e.t.c.

Suborder Haplorhini have a plate which cause a separation between the temporal fossa and eye socket.

Family Hominidae include group of animals that have well developed forearms and flattened digits nails.

Humans are called homo sapiens which means wise man. It is a Latin word...

Homo means man and sapiens means wise.

Need help with this evolution chart some I've filled in yet I'm not sure if they are correct.Plz help anybody
Svetllana [295]

Answer:

This is correct. The remaining portion:

Sympatric species that form interrelationships undergo coevolution.

Allopatric species in different environments can undergo convergent evolution.

Allopatric species in small populations and under intense environmental conditions can undergo genetic drift.

Explanation:

On the basis of geographical distance, speciation is of two major types:

  1. Sympatric
  2. Allopatric

Sympatric Speciation:

Sympatric speciation is the formation of new species with no gergraphical separation from the ancestor. The new and parent species both exist in the same environment but do not interbreed due to mechanisms of reproductive isolation. These involves both prezygotic and post zygotic barriers to reproduction such as timing of mating, sensitivity to pheromones, choice of mating sites or infertility and mismatched gametes. Species formed through sympatric speciation can form interrelationships and undergo coevolution i.e. the evolution of ones species is dependent on the other.  

Allopatric Speciation:

It involves the geographical separation of the parent and new species. These species could be geographically separated by a river, mountain range or land mass.

Although, allopatric species evolve independently, they may develop similar characteristics that serve different functions. Allopatric species in radically different environments undergo convergent evolution i.e. species evolve similar characteristics without any ancestral homology.

Allopatric species that reside in small populations and are under harsh environmental pressures undergo a rapid genetic revolution i.e. genetic drift. This includes the Founder's and bottleneck effect that involve the continuation of a species from very few individuals after a drastic, sudden environmental change.

If the DNA sequence TTCACG is transcribed to AAGGC, what type of mutation has occurred?
kenny6666 [7]
The answer is d. deletion.

If the DNA sequence is TTCACG, it is expected to be transcribed into AAGUGC.
But, it was transcribed into AAGGC. If we count nucleobases, a transcribed sequence has 5 nucleobases, while DNA sequence has 6 nucleobases. These means that deletion happened.
If insertion occurred, there will be 7 nucleobases in transcribed sequence. In substitution or translocation, the transcribed sequence will be the same size, but with different sequence than the DNA sequence.

1. How does base pairing differ in RNA, compared to DNA?
Setler79 [48]

Answer:

A. A pairs with U

Explanation:

In DNA, the nitrogenous bases are A, T, G, and C. In RNA, the nitrogenous bases are A, U, G, and C.

A pairs with U in RNA because it requires less energy to use uracil over thymine.

Hope that helps.
