Answer:
Human impacts on marine ecosystems. Human activities affect marine ecosystems as a result of pollution, overfishing, the introduction of invasive species,and acidification, which all impact on the marine food web and may lead to largely unknown consequences for the biodiversity and survival of marine life forms.

Answer:
33.3 cM
Explanation:
Parent 1: blue shell, long antenna : BBLL
Parent 2: green shell, short antenna : bbll
BBLL X bbll :
F1 : BbLl ( blue shell, long antenna )
BbLl X bbll :
BL/bl = 82 : Parental
bl/bl = 78 : Parental
Bl/bl = 37 : Recombinant
bL/bl = 43 : Recombinant
Total = 240
Recombination frequency = (Number of recombinants/ Total offspring)*100
= (80/240) * 100 = 33.33 %
Map distance = recombination frequency
Hence, map distance = 33.3 cM
Answer:
I believe its C
Explanation:
A neuron is what makes up an atom, so a neuron would go first, then nerve tissue, central nervous system, and then finally human being.

Answer:
An organism is <u><em>homozygous</em></u> for a gene if it has two copies of the same allele for the gene.
The genotype of an organism and the interaction of the genotype with the environment determine the organism’s <u><em>phenotype</em></u> , or observable characteristics.
The law of independent assortment states that the separation of alleles for one gene are independent of that of other genes, unless the genes are<u><em> not linked.</em></u>
Mendel’s law of<u><em> segregation</em></u> governs which allele is expressed in an individual.
Explanation:
A homozygous trait can be described as a trait in which both the alleles of the gene are the same. Heterozygous means that the alleles of the gene will be different.
Genotype is the genetic makeup of an organism where as phenotype of the physical appearance of traits.
Mendel formulated two laws: Law of dominance and Law of Independent Assortment.
