A scientist discovers a fossil of an animal and places it in the fossil record. The organism’s bones are similar to the bones of animal T, which appears earlier in the fossil record. Which conclusion is most reasonable?(1 point) The fossils came from the same organism.

The fossils are from an ancestor of animal T.

The fossils are from animals that lived at the same time.

The fossils are from a descendant of animal T.
2. Why do organisms evolve?(1 point)

Organisms naturally select traits that help them survive and reproduce.

Organisms with traits that help them survive and reproduce in their environment pass on those traits.

Changes in the environment cause organisms to change.

Organisms make changes to help them survive and reproduce in their environment.
3. Scientists examine fossils from three different animals. They determine that all three animals share similar structures and record their observations as follows:

Animal A and animal B have somewhat similar structures.
Animal A and animal C have very similar structures.
Animal B and animal C have very similar structures.
The scientists use the similarities to determine the order in which the fossils should appear in the fossil record. Based on the scientists’ observations, which order is the most reasonable?

(1 point)

B, A, C

A, C, B

A, B, C

C, B, A
4. Scientists discover fossilized bones from two different animals. The scientists consult the fossil record to learn more about the fossils. Which question will the fossil record best answer?(1 point)

How are the animals related to modern animals?

What killed the animals?

Which animal was better equipped to survive?

Which animal is older?

A. The fossils cam from the same organism

Hope this helps!

Explanation:

answer: decrease

a limiting factor is the one which decrease the abundance, distribution and causes extinction of the population of species in a ecosystem. here, predators including hawks, owls and snakes are the limiting factor for the population of mexican free tailed bat.   although bats are nocturnal animals as they forge for food at night these predators also may remain active during night which can decrease the population of the mexican free-tailed bats. also, these bats eat only one type of insects that are moths. the food can also be a limiting factor as all 400 members are dependent upon same type of food needs that are moths. the decrease in the moth population can cause decrease in population size of the mexican free-tailed bats.

therefore, the scenarios will most likely to decrease the population size of the mexican free-tailed bats.  

cells use diffusion to get substances in and out of themselves. that diffusion will occur across the cell membrane or the outer covering of the cell. because we are talking about the surface of the cell, surface area and volume are  important factors here. as a cell increases in size, its surface area and volume increase as well.  we call that the surface area to volume ratio (sa: vol).  but the catch is that  volume increases at a greater rate than surface  area. in other words, as a cell gets bigger, the sa: vol gets smaller. so a really small cell like bacteria is mostly cell membrane (surface) with very little contents (volume). a really big cell like an egg, is mostly insides with a super thin membrane. so what ends up happening is that the cell cannot efficiently diffuse all of the stuff it needs in/out to survive. therefore cell size is limited to about 100mm. so how do we make organisms bigger than 100mm? cells divide! by dividing and becoming multicellular, organisms are able to grow!   check out the diagrams i attached to see the effect of sa: vol. i hope this ! good luck!
