Answer:
Molecules can be made of one type of element pr a mixture of element.
Molecule is two or more atoms bonded together.
Compound act like a different substance (because have different properties from its constituent elements).
Explanation:
A molecule is the combination of one or more atoms. These atoms may be from different elements are of the same elements. All the compounds are molecule but not all the molecules are compound. For example,
H₂O is a water molecule and also a compound. H₂ is just a molecule not a compound because both atoms are from same element.
The compound have different properties from its constituent elements. e.g water is compound made up of hydrogen and oxygen. Hydrogen is flammable gas and oxygen support combustion, while water doesn't have these properties. However in mixture elements retain their own properties that's why mixture is different from the compound.
Answer:
HUMAN BEINGS AND OTHER ANIMALS EXCEPT PLANTS ARE HETEROTROPHS
Explanation:
HETEROTROPHS ARE ORGANISMS THAT CAN NOT MAKE THEIR OWN FOOD
E.G Human beings and other animals
Skeletal muscle – the specialised tissue that is attached to bones and allows movement. Together, skeletal muscles and bones are called the musculoskeletal system (also known as the locomotor system).
Answer:
The correct answer is : The dominant form of the trait shows.
Explanation:
In simple dominance, the attribute related to the prevailing or dominant allele is communicated while the character related to the latent or recessive allele is persecuted or masked. For instance –
Taking a bloom where the dominant allele attribute is red shading and the recessive allele characteristic is white shading. At the point when a posterity of this bloom is created containing one prevailing or dominant allele and one passive allele, its shade would be red simply because just the predominant allele communicates its characteristic.
Thus, the right answer is: The dominant form of the trait shows.
