Answer:
Independent Variable: Hours of sleep
Dependent Variable: Test scores
Experimental Group: Group A
Control Group: Group B
Explanation:
Hours of sleep is the independant variable because it is the factor being tested by the teacher. This is the factor that can be controlled.
Test scores is the dependant variable because it is the factor being affected by the changes in the independent variable. This is the variable being measured.
Group A is the experimental group because this is the one that has been altered or changed from what is normal.
Group B is the control group because nothing is being changed in this group but simply measured as a basis for comparison.

At the Equator, the Sun's rays strike the Earth at a right angle, which makes the heat more intense and concentrated over a small area.
Answer:
<h2>All deuterostomes exhibit radial symmetry in their bodies.</h2>
Explanation:
deuterostomes : All deuterostomes are triploblastic and have 3 layers:
i) endoderm, ii) mesoderm and iii) Ectoderm
In deuterostomes , a mouth that develops separately from the blastopore.
Taxonomically, the deuterostomes defines as any member of the phyla (Chordata, Hemichordata, Echinodermata, etc) in which the anus appears first, and it develops at or near the blastopore.
All deuterostomes have a coelom.
All deuterostomes have a similar pattern of early embryonic development.
Explanation:
Conservation of Energy in Living Systems
Energy changes form as it flows through an ecosystem, but the total amount of energy in the system remains constant. Food chains show how energy flows in an ecosystem. ... The chemical energy stored in producers is passed to consumers, organisms at higher levels on the food chain.
