Rifting events:

• crustal up-warp,

• rift valley (linear-shaped lowland between several mountains)

• linear sea,

• ocean

Development of the rift starts when the upper part of the lithosphere starts to extend. Extension leads to the development of isolated basins. Major rifts occur along the central axis of most mid-ocean ridges, between two tectonic plates.

Why do you get thirsty after eating salty food osmosis.

ziro4ka [17]

Answer:

As the saltier blood circulates through the body, it makes the fluid outside of our body cells saltier than the fluid inside the cells. The cells notice the change right away. That's because the extra salt outside acts like a magnet, pulling water out of the cells.

In man, assume that spotted skin (S) is dominant over non-spotted skin (s) and that wooly hair (W) is dominant over non-wooly ha

Brut [27]

Answer:

Total four genotypes and its frequency

SsWw – 4/16

ssWw- 4/16

Ssww - 4/16

ssww - 4/16

Phenotype –

SsWw – Heterozygous Spotted skin and heterozygous wooled hair

ssWw - Homozygous non-spotted skin and heterozygous wooled hair

Ssww - Heterozygous Spotted skin and Homozygous non -wooled hair

ssww - Homozygous non-spotted skin and Homozygous non -wooled hair

Explanation:

Given -

Allele for spotted skin is "S"

Allele for non-spotted skin is "s"

Allele for Wooly hair is "W"

Allele for non-wooly hair is "w"

Allele "S" is dominant over "s"

And Allele "W" is dominant over "w"

Cross is carried out between heterozygous spotted, non-wooly man and heterozygous wooly-haired, non-spotted woman

Genotype of heterozygous spotted, non-wooly man - Ssww

Genotype of heterozygous wooly-haired, non-spotted woman - ssWw

Ssww * ssWw

In 2006, scientists found a fossil that seemed to have fish-like scales and four legs. It also had a bone structure in its neck

lianna [129]

Answer:

Option-C

Explanation:

Scientists found a fossil of a fish with four limbs or legs. The fossil was estimated to be around 375 million years old.

The fossil showed the fins and scales of a fish but they also possess the bones of proto-wrist, shoulders and the elbow.

The presence of these bones can be a clue that the fish evolved the limbs to walk on the land and will later evolve into animals belonging to amphibians, reptiles and mammals. Therefore, the Tiktaalik is considered the missing link of how life evolved from water to land.

Thus, Option-C is correct.

after the brain receives information from the body's sensory receptors, what is the next step in responding to this information?

Bumek [7]

The sensory receptors refer to the portions of the nervous system, which sense variations in the external or internal surroundings. The sensory input can be in various forms, comprising taste, pressure, light, sound, pH of blood, or levels of hormones, which are transformed into a signal and are transmitted to the brain or spinal cord.

In the sensory centers of the brain, the barrage of information is integrated and a response is produced. The response, that is, a motor output refers to a signal conducted towards organs via motor neurons, which then transforms the signal into some kind of action, like changes in heart rate, movement, discharge of hormones, and others.

dimaraw [331]

Phenotype for LL would be the dominant trait shape for the ear. Phenotype for Li would also be the dominant trait shape. Then for ii the phenotype would be the recessive option. The probability for LL is 50% probability for Li is also 50% and for ii it would be 0% based off what you have shown. Sorry I don’t know what the exact name for the recessive and dominant shape of the ear shape
