Answer:
Tendons connect the bones.
Explanation:
The muscles are connected to bones through tendons, and this way the contraction of the muscle helps the movement of the bones through them.
The muscles work in pairs and in this way they move. While one muscle is contracting, the other one relaxes.
The muscles work in a form of contraction-relaxing. The flexor contracts to bend a limb at a joint.
On a scratch sheet of paper, complete the Punnett square of the cross between two heterozygous red-eyed flies (Rr). What color eyes will the offspring have?
Answer:
75% red, 25% other color (brown?)
Explanation:
A cross between two heterozygous red eye flies (Rr x Rr)
R r
R RR Rr
r Rr rr
The possible genotypes are RR, Rr, and rr. There are two possibilities of Rr.
Since the heterozygotes have red eyes, the red eye allele must be dominant. Therefore, RR and Rr genotypes will all have red eyes. That means 3/4 (75%) of offspring will have red eyes. 1/4 25% are h0m0zygous recessive (rr), and will therefore have the other eye color (question doesn't mention which colour this is, it is likely brown)

Differences: Their basic anatomical structure became adapted for different habits and habitats.
They have different numbers of carpals, phalanges, and different lengths and shapes of bones. Plenty of ways, actually!
12. DNA in organisms cells
13. The organism may share a common ancestor.
14. Humans and dogs have similar shape and length of bones. You could also say dogs and whales have the same number of bones but that’s kinda a sucky observation.

How does the presence of coal in Antarctica provide evidence for continental drift?
Answer:
There have been glacial deposits founded in the tropics and coal founded in Antarctica. This supports the theory of the Continental Drift, because coal originates from tropical plants, which can only be founded in the tropics. Additionally glacial deposits can only come from Antarctica, proving the theory.

Which process is illustrated in this picture, given that the particles shown are water molecules?
a) diffusion b) osmosis c) endocytosis d) active transport
Like, right now
Answer:
The answer is A diffusion
The process which is illustrated in the given picture shown by water molecules is that of diffusion.
What is diffusion?
Diffusion is defined as the process of movement of molecules which takes place under concentration gradient. It helps in movement of substances in and out from the cell.The molecules move from lower concentration region to a higher concentration region till the concentration becomes equal.
There are 2 main types of diffusion:
1) simple diffusion-process in which substances move through a semi-permeable membrane without the aid of transport proteins.
2) facilitated diffusion- It is a passive movement of molecules across cell membrane from higher concentration region to lower concentration.
There are 2 types of facilitated diffusion one is osmosis and dialysis.

A lamp that plugs into a wall socket draws energy which flows through a thin wire in the bulb causing it to glow. What energy transformation are taking place?
choices:
Chemical>light>electrical
Mechanical>sound>light
Thermal>solar>electrical
Electrical>thermal>light
Answer:
Electrical>thermal>light
Explanation:
Electrical energy refers to energy which is gotten from potential energy. This energy source could be a wall socket.
Thermal energy on the other hand refers to internal energy of a system where temperature is constant.
Light energy is made up of photons which transmits electromagnetic radiation which move in waves and become visible to human eye.
Therefore, the energy transformation taking place according to the question is option D.
Select all that apply.

There are two continents with an ocean between them. Today, the continents have very different plants and animals on them. However, a geologist found fossils of the same type of organism on both continents. Millions of years ago, when this type of organism was alive, we know it lived in only one place. The geologist is using the fossils as evidence to argue that the two continents used to be touching. How could the continents have gotten so far apart, and how long did it take for this to happen?
Answer:
The continents could have gotten so far because of plate tectonic movement. We know that the plates are always moving so if these plates were very active then it would have caused supercontinent pangea to drift apart. This process must have taken more than a million years to happen.
