What can you say about the environments of these widely seperated layers

Biology
1 answer:
Alika [10]2 years ago
4 0

Answer:

This means that the two separate rocks were once part of one piece of rock. These layers got separated most probably by continental drift as a result of tectonic plate movements. An example of such a fossil is the Mesosaurus, a freshwater crocodile-like reptile, that is found in Southern Africa and Eastern South America continents- that means they were once one land mass.

The environment in these two separate layers would most likely be different. As the layers drift apart from each other , they drift across latitudes that are determinants of climate in a region. Therefore, even the organisms in these two rock layers will evolve differently (even though they will share a common ancestor) in adaptation to respective environments – this is called allopatric speciation.

How do substances get into and out of the cell?
viva [34]

Answer:

Water, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion (or a type of diffusion known as osmosis ).

Select the correct answer from each drop-down menu.
gtnhenbr [62]

Answer:

1. Minimum viable population is the estimate of the fewest number of organisms a population needs to avoid extinction.

2. The measurement will most likely stay the same if the number of offspring each female in the population produces increases.

3. If the death rate increases, this measurement will most likely increase.

Explanation:

Minimum Viable Population:

  • Minimum viable population is an ecological threshold that signifies the minimum number of individuals required to prevent the species from going extinct.
  • MVP determines population conservation benchmarks.
  • MVP also helps in keeping a population genetically diverse as a limited number of individuals present limited mating opportunities and therefore limited genetic diversity.

which statement best captures george vaillant's view of development? question 11 options: biology is the map of life events. kee
notsponge [240]

George Vaillant's view of developmental biology is the map of life events. keeping on time will keep one's self well-adjusted life requires a constant series of adaptations. culture determines the life cycle. <u>Life requires a constant series of adaptations.</u>

<u />

Life cycle, in biology, is the series of modifications that the individuals of a species undergo as they bypass from the beginning of a given developmental level to the inception of that identical developmental stage in a subsequent era.

A life cycle ends when an organism dies. In standard, plants and animals go through 3 simple tiers in their lifestyles cycles, starting as a fertilized egg or seed, growing into an immature juvenile, and then ultimately transforming into a grownup.

A life cycle approach can assist us to make picks. It implies that everybody within the complete chain of a product's life cycle, from cradle to grave, has a duty and a function to play, contemplating all of the relevant effects on the economic system, the environment, and society.

Compared to the upper paleolithic, mousterian ____. burials are more complex, usually containing hundreds of tools burials usual
grin007 [14]
I believe the answer is none of these. The mousterian is defined by stone-knapping known as levallois. Mousterian burials are supported by morturt behavior and are not complex. The burials represented the individual who are singled out for treatment by mortuary. Most burials were done in caves and shelters where adults were mostly buried at the center.<span />
