Answer:
The two species concepts that are most likely to place dogs and wolves together into a single species are <u><em>biological and phylogenetic</em></u> concepts.
Explanation:
- The biological species concept establishes that a species is a group in a population whose individuals can mate and have viable, fertile descendence. These groups are also reproductively isolated from other groups or species. This is, the members of a species can not reproduce with the members of other species, or they can their progeny is unviable.
- The phylogenetic species concept refers to a species as the monophyletic group that is less inclusive for organisms. It is a group of organisms that share an ancestor in common and can distinguish from other similar groups. In this concept, a unique species can include a wide phenotypic variability.
Answer:
Looking at the sky during night is always an amazing scene. It takes our breath away, every time when we see the night sky with countless stars twinkling, full moon and planets. I always wished I reach those far planets travelling in space. The only way I can fulfill my dream is to become an astronaut. Astronaut is a person who is trained to travel in a spaceship to go to outer space. If I were an astronaut, I wish my first mission will be to the moon. However, I will have to undergo a very strict training to survive in space We all have seen the training videos of astronauts in DISCOVERY channel where they even undergo underwater training. Life in space will be different with zero gravity and so we will experience zero weight and will float freely. Wow!!!! that seems to be an exciting thing. But how we will eat and drink?
A claim is an unverified statement or theory which is made about something which may or may not be true.
<h3>Verification of a claim</h3>
For a claim to be validated, i.e, proven to be true (in science), then there needs to be tests and experiments which needs to be carried out to show that the claim is valid.
With this in mind, if for example if there's a claim that jewelweed helps to treat symptoms caused by poison ivy, then there needs to be a controlled experiment to see if this is true or not.
If after a series of experiments and it can be established without any iota of doubt, then the claim is valid and the scientific process will move to the next stage.
Please note that your question is incomplete so I gave you a general overview to give you a better understanding of the concept.

Answer:
C
Explanation:
Because between the earth and sun is empty space (vacuum) transfer of heat from the sun to earth can only occur through radiation- because convection and conduction require a medium. The is the same process that warms your hands when you place them beside a fire. When you put your hands above the fire, they are warmed through convection.
