They would know if they see anything like traces of water or anything else that would be nessecary for a living organism to have. They look for these with technology like the hubble telescope as well as the drone on Mars to gather as much information as possible.
It is located At the umbilicus
At 20 weeks' gestation, the fundus can be palpated at the
umbilicus. A fundus of 12 weeks' gestation is palpated at the symphysis pubis.
At 16 weeks' gestation, the fundus is midway between the symphysis pubis and
umbilicus. At 36 weeks' gestation, the fundus can be palpated just below the
ensiform cartilage.
Answer:
Heredity is a term that refers to something we have gained from our parents, they can be some physical traits like appearance or behavioral traits like generosity, ethics etc.
When we talk about development of an individual, science has proved that both heredity and environment play a crucial role. There is no doubt that certain things are predetermined in our genetic make up like our height, weight and complexion etc but there are several ways in which environment influences and modifies those traits.
Let's take some examples:
- A kid is born in Africa whose parents inherited just appropriate and ideal height and intelligence to him, But he was surrounded by the conditions where he could not get sufficient food , minerals and nutrients that hindered not only his physical growth and development but his intelligence level did not reach that potential too that was predetermined in his genes. So, we can say that environment influenced the kid and modified the traits he inherited from parents.
- Similarly, there are many boys that inherit fair complexions from their parents but they have a lot of sun exposure due to out door sports and activities. So, parents observe that after teens their complexion is getting towards darker tone although in preadolescence they were just as fair as other siblings. This is proven by studies that sun exposure turns the skin tan and darker than original tone.
Therefore, we can say that both Heredity and environment play an important role in determining human development and behavior.

Answer:
Reduction in secondary pollutants
Explanation:
Reduction in secondary pollutants is not a possible consequence of global warming.
The building blocks of protein are C. AMINO ACIDS.
Amino acids are made up of a center carbon atom bound positively to a charged amino group and a negatively charged carboxyl group and a side chain.
The primary structure of a protein is the sequence of an amino acids that are attached together by a peptide bond
The secondary structure of a protein, the polypeptide is folded through the mechanisms of amino acids rotating around bonds folding into a helix or a pleated sheet structure and stabilized by a hydrogen bond.
