I deceided to do the project with fresh water from my creek in the backyard. I was hoping to get some living organisms in the water when i scooped it up.The first week there wasnt many changes i did notice the water was turning slightly a different color but no major changes. The secound week my water was more of a green color and not as much brownish clear. There was also some green stuff growing which i think that was alge.The third week my water was all the way green and i noticed there was some stuff floating in the water but i dint see any living organisms. There was also more alge in it than last time.

Sperm and eggs are found in different parts of plants. Explain why it is important for these
cells to unite, and describe some factors in an environment that help unite them.
Explanation:
When sperm and eggs in plants are united they fertilize the egg creating a plant able ready seed. Some factors in an environment that help them unite are; (animals) bees, butterflies, and other insects. wind bringing pollen around
When sperm and egg (found in different parts of plant) unite fertilization takes place which results in the formation of a zygote and later it forms an embryo.
Some factors in an environment that help unite them are air, water, insects, birds, bats etc.
What is sperm?"Sperm is defined as male reproductive cell. In case of plants, it is known as male gametophyte (pollen)."
What is egg?"Egg is defined as female reproductive cell. In case of plants, it is known as female gametophyte (ovum)."
What is fertilization?"Fertilization can be defined as the fusion of the male gametes (pollen) with the female gametes (ovum) to form a diploid zygote."
What is a zygote?"A zygote is a cell formed by the union of two gametes."

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.

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
