Adaptation

s9169624_ — 2024-03-11 13:27:24 UTC

A characteristic that improves an individual's ability to survive and reproduce in a particular environment.

Species

s9182026_ — 2024-03-11 13:28:01 UTC

A group of organisms that are closely related and can mate to produce fertile offspring

Evolution

s9182026_ — 2024-03-11 13:31:27 UTC

The process in which inherited characteristics within a population change over generations such that new species sometimes arise

Q1. Members of the same species can mate with one another to produce offspring.

Fossil

s9182026_ — 2024-03-11 13:33:11 UTC

The trace or remains of an organism that lived long ago, most commonly preserved in sedimentary rock

Q2. A(n) fossil helps an organism survive.

s9168094_ — 2024-03-11 13:33:29 UTC

Q3. When populations change over time, evolution has occurred.

Lily's Facts

s9169624_ — 2024-03-11 13:37:07 UTC

The fossil record provides evidence about the order in which species have existed.
Organisms contain evidence that populations and species undergo changed in traits and DNA over time.

Trait

s9182026_ — 2024-03-11 13:37:56 UTC

A genetically determined characteristic

Q.5 - They show that by the fossils found in the Earth's crust.

Selective Breeding

s9182026_ — 2024-03-11 13:40:13 UTC

The human practice of breeding animals or plants that have certain desired traits

Q.4 - A. Have similar kinds of bones.

Natural Selection

s9182026_ — 2024-03-11 13:43:07 UTC

The process by which individuals that are better adapted to their environment survive and reproduce more successfully that less well adapted individuals do; a theory to explain the mechanism of evolution

Generation Time

s9182026_ — 2024-03-12 12:39:22 UTC

the period between the birth of one generation and the birth of the next generation

Speciation

s9182026_ — 2024-03-12 12:41:08 UTC

the formation of new species as a result of evolution

s9169624_ — 2024-03-12 12:42:10 UTC

Q.6- Scientists think that modern whales evolved from ancient, land dwelling mammal ancestors.

s9169624_ — 2024-03-12 12:56:39 UTC

Q.7- Whales are mammals and they take in oxygen through their blow holes and fish breathe out oxygen through their gills

Gabbie's Facts

s9169624_ — 2024-03-12 13:05:46 UTC

When scientists compare organism's traits, such as skeletal structures, much of the information that they get supports the theory that organisms share a common ancestor.
The greater the number of similarities between the data sets for any two species, the more closely the two species are related through a common ancestor.

Q.8- A persons DNA is likely to be more similar to their parents because you get your DNA from both your parents and either your aunt and uncle have some of the same DNA as the person but it is almost exactly like your parents because it is directly passed down.

Annabelle's Facts

s9169624_ — 2024-03-12 13:13:49 UTC

Scientists think that the ancient ancestor of whales was probably a mammal that lived on land and that could run on four legs.
The layers of the earth are made up of different kinds of rock and soil stacked on top of each other.

Q.9- Layer C because it has been there for a longer amount of time because the other layers have been building up over the top of layer C.

Audrey's Facts

s9169624_ — 2024-03-12 13:17:31 UTC

Fossils usually form when a dead organism is covered by a layer of sediment.
Over time, more sediment settle on top of the organism that then turns into a fossil.

(Section 2) Q.1- A quality or characteristic that is determined by genetics

s9182026_ — 2024-03-12 13:20:31 UTC

(Section 2) Q.2- selective breeding and natural selection are opposites because selective breeding is when humans choose what animals to breed and selective is when nature does it.
