Environmental Sustainability Environmental sustainability is the process of making sure current processes of interaction with the environment are pursued with the idea of keeping the environment as pristine as naturally possible based on ideal-seeking behavior. What makes environmental sustainability so important is that it demands that society designs activities to meet human needs while indefinitely preserving the life support systems of the planet. Human consumption can only use the nature’s resources at a rate that can be replenished naturally. Human Values affecting Society The most devastating environmental change of all is the loss of biodiversity.

Answer:
A.a woman heterozygous for hair curl, a man heterozygous for hair curl will produce 25% straight hair, 75% curly hair
Explanation:
a woman heterozygous for hair curl, a man heterozygous for hair curl will produce 25% straight hair, 75% curly hair
using C as the allele for hair curl:
Cc x Cc will produce the following genotypes: CC, Cc, Cc, cc
25% will be homozygous dominant (curly hair)
50% will be heterozygous (curly hair)
25% will be homozygous recessive (straight hair)
combine the curly hair genotypes since the question asked about phenotypes which results in 75% curly and 25% straight.

Answer:
9:3:3:1
Explanation:
If alleles of two genes separate randomly during anaphase-I of meiosis, some new combinations of the alleles are formed in the gametes. A heterozygous genotype for two loci (let's support TtRr) produces a total of four types of gametes in 1:1:1:1 ratio (TR, Tr, tR, and tr). The random fusion of these gametes from two double heterozygous parents (TtRr x TtRr) gives a phenotype ratio of 9:3:3:1. Here, 9/16 F2 progeny exhibit dominant phenotype for both loci while 1/16 exhibits recessive phenotype for both the genes. Rest 3/16 and 3/16 F2 progeny express dominant trait for one gene and recessive for the other.
I believe the answer you are looking for is a cell cavity. Also known as: Cavity of cell, or cell space
