The answer is C genetic variation
Time : because the more mass the faster the speed because u know kinetic energy and height can affect potential
Answer:
eagle- chordata phylum
ladybud- Insecta class
scorpian- Arachnida class
lobster- Crustacea class
snail- Mollusca phylum
Explanation:
The organism that contains a notochord at some of its life cycle stage are called chordates and all vertebrates are chordates so eagle comes under phylum Chordata.
Insecta is the largest class of phylum Arthropoda which contains organisms which have jointed legs, exoskeleton and segmented body for example ladybird, playing mantis, etc.
Arachnids are animals which have jointed legs and in this class spider are the largest order which contains scorpions, mites, ticks, etc.
Crustaceans are invertebrates which have hard shell made up of calcium for example lobster, prawn, shrimp, etc.
Mollusks are very large invertebrate phylum which contains a soft segmented body that is usually present inside a shell made up of calcium. for example snails.
Answer:
HYPOTHESIS: IF the salinity of the solution decreases, THEN the vegetable mass increases.
Explanation:
Hypothesis, in an experiment, is a testable explanation or prediction made to solve an observed problem or answer a question. It shows how one variable called independent variable affects another variable called dependent variable. It is usually written in the "IF, THEN" format.
In this case, the question states that there is a relationship between vegetable mass and salinity of the solution. This means that the question has been asked that "Why is the vegetable's mass affected by salinity of a solution". Hence, a hypothesis can read:
IF the salinity of the solution decreases, THEN the vegetable mass increases.
