Leeches are parasitic because they suck blood not giving any benifit but harm.
They cause climate change by trapping heat, and they also contribute to respiratory disease from smog and air pollution. Extreme weather, food supply disruptions, and increased wildfires are other effects of climate change caused by greenhouse gases.
Answer:
Parent 1: G gametes
Parent 2: g gametes
Explanation:
This question involves a single gene coding for seed color in pea plants. The allele for green seeds (G) is dominant over the allele for yellow seeds (g). This means that a plant that is heterozygous (Gg) will possess green seeds.
If two parents are about to cross in such a way that Parent 1 is homo-zygous for green seeds i.e. GG, while Parent 2 is homo-zygous for yellow seeds i.e. gg.
- Parent 1 (GG) will produce only "G" gametes
- Parent 2 (gg) will produce only "g" gametes
The correct answer is letter C. Eugenics is the science of improving hereditary qualities. It came from the Greek word, eugenes, which means "well-born race, stock, kin." This is a practice of beliefs that aimed at improving the quality of genes of a particular human population. Much like the way that Spartans bred their offsprings where they made sure that only the best quality genes are present in their population.
An interdisciplinary study means it encompasses other branches. So, biology as an i<span>nterdisciplinary study</span> encompasses other sciences. Biology can be related with other sciences like chemistry, microbiology, molecular biology, physiology, systematics, taxonomy, statistics, ecology, genetics. The allied fields are endless. All these share a common goal. Like statistics, biology, ecology and genetics can be used in population biology.
