Why is an ecosystem with higher levels of biodiversity more stable than an ecosystem with lower levels of biodiversity?
O because species are more adaptable
O because they are better able to withstand stresses like disease or climate change
because changes affect every species the same way
because species are constantly replacing one another
An ecosystem with higher levels of biodiversity is more stable than another with lower levels because they are better able to withstand stresses like disease or climate change.
What is biodiversity?The term biodiversity refers to all of the variations (both genetic and phenotypic) in a given population.
Biodiversity is a fundamental subject to maintaining the equilibrium (homeostasis) of the whole ecosystem.
Higher biodiversity allows populations to face environmental changes such as diseases or climate change.

In pea plants, petal coloration of has a complete dominance relationship where purplepetals are dominant over white petals. There are 276 plants, 273 have purple petals.Find: the frequency of the dominant and recessive alleles and the frequency ofindividuals with the dominant, heterozygous, and recessive genotype.
Answer: See below
Explanation:
In the selected pea plant population, there are total 276 plants out of them 273 have purple petals.
Remaining 276 - 273 = 3
q²= 3/276
q²= 0.010
q = 0.1
p + q = 1
p = 1 - 0.1
p = 0.9
Therefore:
Homo-zygous dominant = p² = 0.9×0.9 = 0.81
Hetero-zygous dominant = 2pq = 2×0.9×0.1 = 0.18
Homo-zygous recessive = q² = 0.1×0.1 = 0.010

2. Discuss why a four chambered heart is more efficient than a two chambered heart in delivering oxygenated blood to the various body parts. What evolutionary changes in the lifestyles of organisms selected for the evolution of the four chambered heart?
As organisms became more active, a four-chambered heart was selected for because of its ability to separate oxygenated and deoxygenated blood.
Why is a four-chambered more efficient in oxygen delivery than a two-chambered heart?A four-chambered heart is a heart consisting of four chambers, namely;
upper ventricle lower ventricle upper atrium and lower atriumA four-chambered heart is more efficient in oxygen delivery than a two-chambered heart because it does not allow for mixing of oxygenated and deoxygenated blood.
