1) False. Scientists may predict something but realize a difference soon after before the test, so they could definitely change the hypothesis if they want. It’s only AFTER the experiment they cannot. Because a hypothesis is like a “guess” as to what’s going to happen, right?
2) False. A hypothesis can’t be “valid” because it’s literally a prediction.
3) True. Especially if you’re doing a chemistry lab, it’s really important things are done in order or else the product might result as something else you were expecting, or can be very dANGEROUS
4) True. The conclusion must be based on data because it’s the observation that was seen.
Hope this helps!! I could have answered in short form but I just wanted to make them understandable:)

The invertebrate chordates include Tunicates and lancelets.
<h3>What are invertebrate chordates?</h3>
They are a group of chordates that possess notochords somewhere in their life span but end up not possessing the vertebral column. They possess all the characteristics of chordates.
Invertebrate chordates include the Urochordata which are the Tunicates and the Cephalochordata which are the lancelets.

Answer:
Physiology, behavior and morphology are considered as phenotype of an individual as these attributes can be observed. Example of phenotypes include wing length, hair color, skin color and height.
<u>There are basically two factors that influence the phenotype:</u>
<u>(1) Genotype or Genetic information of the individual:</u> Some of the phenotypes such as height and skin color are transmitted genetically from generation to generation. Genetic information is the transfer of genes that carry some of the specific genetic information and pass it to another generation which is visible in their phenotype.
(2)<u> Environmental influence:</u> As the phenotype attributes are variable so they are highly influenced by the environment or surrounding they are living. Environmental condition such as temperature, diet, humidity, oxygen levels, and the presence of mutagens affects the phenotype of an individual.
Hence, Genotype and environmental factors influence an individuals phenotype.
