Answer:
Environmental change results in the environmental ecosystem to be able to adapt to a new environment to survive the impact of environmental change can cause a decrease in the amount of organisms living in that ecosystem and without one of the organism living in the ecosystem the other organism supports on the other organism for food/energy will be scarce resulting in a decrease of species eventually dying out.
Answer:
Is light needed for photosynthesis?
1. Destarch the plant (remove previously made starch from plant)
2. a. cut the leaf in 2
b. 1 part in an opaque box and 1 part in a transparent box (one with light and one without)
3. Test for starch (BEWI)
B. Is carbon dioxide needed for photosynthesis?
1. Destarch the plant (remove previously made starch from plant)
2. a. cut the leaf in 2
b. 1 part in a box with CO2 absorber and 1 part in box with a CO2 provider
3. Test for starch (BEWI)
C. Is chlorophyll needed for photosynthesis?
1. Destarch the plant (remove previously made starch from plant)
2. Use a variegated leaf
3. Test for starch (BEWI)
B E W I
1. Put leaf in boiling water to destroy the cell membrane and denature enzymes
2. Ethanol in a hot water bath to remove chlorophyll
3. Warm water to soften the leaf
4. Add drops of iodine solution
Explanation:
Answer: Although both are X-linked recessive conditions, and therefore more likely in males, with the single X-chromosome. The recessive allele in colour blindness occurs at a higher frequency in the population and is a mild condition. Thus colour blindness does occur to a lesser extent in females because it needs the double recessive condition. DMD is a severe, disabling condition with a limited lifespan, and recessive allele frequency much lower, so the double recessive condition in females is very rare.
Explanation: DMD is an X-linked recessive, “nearly always in males” suggest that it also occurs due to a new mutation or some rare condition e.g. double recessive from an affected father and carrier mother, or inactivation of the normal gene in a heterozygote. It is also found that the defective allele is not completely recessive and that female carriers may exhibit mild to moderate effects.
colour blindness is polygenic, although the genes are all X-linked. It is more common in males than females. Females can carry two recessive alleles and so express the phenotype, but this is uncommon because the frequency of the recessive gene is low.
There are similarities in that both are X-linked recessives, therefore commonly expressed in males, who only have one X chromosome. The gene frequency of the colour blindness recessive is much higher than that of DMD, so the double recessive condition, which affects females, is more likely to be seen with colour blindness. In addition, DMD is a severe condition associated with disability and limited lifespan, which reduces the probability of mating between an affected male and carrier female
A: if the oak trees are I'll then it would affect their health which they'll star dying which means that all the biotic organisms that depended on those oak trees for shelter would also start dying which means all the organisms that depended on the oak tree organisms would also die and so on. That way this small change will affect the whole animal community in that area.
B: this change in biodiversity will greatly affect the sustainability of the forest because the animals dying would disrupt the food chain in that ecosystem while killing the whole forest.
E) be more susceptible to disease and famine
