Answer: Coat color, body structure changes, etc

Explanation: Any type of trait can come from sexual selection, most of the time the animalswith the best traits survive to pass on their trait. There are lots of answers to this question becuase anything benifical to the animal is most likely to be passed on.

Drag each tile to the correct box. Arrange the layers and faults from oldest to youngest.

kaheart [24]

The answers would be:

Layer D

Layer C

Layer B

Layer A

Layer E

Fault F

If you'd like to know why, here's more about the question:

The law of superpo sition states that the lower the layer, the older the rock is.

Looking at the layers alone, we can say that D is the oldest, and C would be next, so on and so forth.

The law of cross - cutt ing relationships, on the other hand, states that a geologic event, like a fault, is younger than the layer that it goes through.

So if we look at the figure given, the fault goes through all the layers, so we can say that it is younger than all the layers.

which of the following shows the levels of organization in a multicell organsim from the smallest level to the largest?

zzz [600]

1. Organelles-. e.g. mitochondria, nucleus.

2. Cells- e.g. epithelial cells, palisade cells.

3. Tissues- e.g. muscles, connective tissue.

4. Organs- e.g. heart, liver.

5. Organ systems- e.g. digestive system, circulatory system

This is because there are many organelles inside a cell and a collection of same cells that creates tissues, a collection of tissues form organs, to carry out a particular function, and a collection of organs working together is an organ system. I think this is what they're after as I had a similar question a little while ago.

Identify the bones and features indicated in this radiograph of the neck

stealth61 [152]

I found this radiography online, i hope it's the same:
1- Spinous process
2- Atlas ( it's the first vertebra)
3- Axis ( it's the second vertebra)
4- Transverse process
5- Intervertebral disc (present between vertebras)
6- body of the vertebra
the occipital bone is a reference that it's the posterior side, while the mandibule indicates it's anterior.
