Answer:
B: I saw it an hour ago and I didn't want to answer because there are too many ifs. I tried, but it could be wrong.
Explanation:
This is not as simple as it sounds and I have a feeling that the correct answer is in the head of the person designing the question. In other words, I could easily get it wrong.
It depends on whether the tide is going in or going out to start with. The question would be a whole lot easier if the bottle was dropped miles from shore.
A: The bottle is capped. A is certainly not true. The low density of the bottle will keep it afloat until something happens that determines it's permanent direction. Not A.
B: It will if nothing else influences it. There will always be waves around that will insure an up and down movement. This is a possible answer, but not a certain one. A five year old could not throw it very far to start with. Let's read the rest.
C: Maybe. It has happened. The bottle needs a good start and the tide going out to happen. Let's read the last 2.
D: Not in a million. Not D.
E: It won't be still. The ocean is always moving. Not E.
I'm going to pick B, but it is not a slam dunk.
The endosymbiotic hypothesis explains that how eukaryotic cells might have evolved chloroplasts and mitochondria within their cells.
The endosymbiotic hypothesis states that the eukaryotes have developed via a procedure whereby distinct kinds of free-living prokaryotes became assimilated within the bigger prokaryotic cells and ultimately evolved into chloroplasts, mitochondria, and various other organelles.

as the question is incomplete i have added the link to full question in ask for detail section.
b) Lysosome
Explanation:
After ingestion of a food particle, pH changes and enzymes contributed by the __Lysosome__ will digest and hydrolyze the ingested particle in the phagocytic vacuole.
Answer:
Just before the cat drops, it was stationery. Therefore it has energy of position called potential energy.As it drops, the Gravitational potential energy is converted to Kinetic Energy,The conversion mid- air is P.E to K.E to P.E to K.E to P.E to K.E, until it touches the ground. As it touches the ground all the energy is converted to P.E energy of position.
As it runs after mouse the P.E is converted back to Kinetic , energy of motion. As it feeds on the mouse , the chemical energy obtained as protein from mouse meat.This is later converted back to Mechanical energy as (kinetic and Potential energy) in the cat.
Explanation:
Answer:
Duplication of hox genes is important in the radiation of animals because they are regulating genes of symmetry and the body plan of the animals' bodies. Some change or mutation in these genes during duplication can cause mutations and with these evolution of the species as it controls the different segments of these animals as they develop, launching the genetic programs that form various body structures, such as limbs and organs. .
