what is an ovum

the female gamete

not the nucleus of the female gamete

format for how energy is transferred in food chain

Processes through which energy is passed (max 4 pt)

P1: During photosynthesis (in plant), light energy to chemical energy + carbon dioxide to glucose OR light energy trapped as chemical energy in glucose molecule A: equation for photosynthesis (must include light as a condition)

P2: When a herbivore/primary consumer eats/feeds on/ consumes plant, energy in plant tissue is passed to animal

P3:When carnivore/ secondary /tertiary consumer eats/feeds on consumer a herbivore/another animal/ primary consumer , energy is absorbed

P4:Correct use of names from food chain in discussion (at least twice)

What happens to energy in a food chain (min 1 pt)

E1: Energy from sun is source of energy for the food chain

E2: Only 10% energy passed from one trophic level to next OR 90% of energy is

lost at every trophic level

E3: Energy flow is not cyclic/ not reused/

evolution format

V = Varieties of the wolf occurs naturally

M = Caused by mutation

E = Env factors – competition of resources / changes to environment/ accept any reasonable environmental factors

F = Survival of the fittest/ variation with favorable genes best suited to the new environmental factors get to survive

R = Reproduce to pass down the favorable genes / alleles

I = Isolation (physical / geographical) prevents breeding with original species

T = Over a long period of time (after many generations)

A = Accumulation of more/other beneficial genes in that variety during the long period of time

G = Leads to a different species that is genetically different from the original

Describe how urine volume and concentration changes with increasing core body

temperature. Explain how these changes are brought about.

D Urine Volume decreases+ concentration increases

E1 Blood water potential drops because of increased sweating

E2 Sensed by hypothalamus / hypothalamus is stimulated + increased secretion of ADH

E3 Increased permeability of DCT and collecting duct of nephron/kidneys + increased absorption of water into blood
