<span>Since the early 1990s, geneticists have produced "genetically modified" crops that yield fruits and vegetables commonly found in U.S. supermarkets. Genetically modified plants (and also applicable to animals) in agriculture are those plants whose DNA are being modified using genetic engineering techniques.</span>
Answer:
Explanation:1. It is known that humans are in fact eating these tiny plastic particles, but fish aren't the only source. Bottled water, beer, honey, sea salt and tea bags have all been exposed as microplastic carriers, just to name a few.
2.The chemicals used in the production of plastic are toxic and detrimental to the human body. Chemicals in plastic-like lead, cadmium and mercury directly can come in contact with the humans. These toxins can cause cancers, congenital disabilities, immune system problems and childhood development issues.
3.Microplastics entering the human body via direct exposures through ingestion or inhalation can lead to an array of health impacts, including inflammation, genotoxicity, oxidative stress, apoptosis, and necrosis, which are linked to an array of negative health outcomes including cancer, cardiovascular diseases,
4.Human penises are shrinking because of pollution, warns scientist. ... Dr Shanna Swan writes that humanity is facing an "existential crisis" in fertility rates as a result of phthalates, a chemical used when manufacturing plastics that impacts the hormone-producing endocrine system
Answer:
46.8% should be. correct, I'm not fully sure though. : )
Answer:
The correct answer is b) 2
Explanation:
When is dissolved in water, silver acetate (AgCH₃COO) is dissociated into ions according to the following equilibrium:
AgCH₃COO ⇄ Ag⁺ + CH₃COO⁻
Where Ag⁺ is a silver cation and CH₃COO⁻ is the acetate anion (an organic anion). As we can see, from one single formula unit are obtained 2 ions (1 cation and 1 anion).
Therefore, the correct option is b) - 2
Answer:
1) -COOH
2) -NH2
3) hydrogen bonds
4) dispersion forces
5) -CH3
6) hydrogen bonds
7) negative
8) negative
9) positive
Explanation:
Alanine has a <u>-COOH</u> and a <u>-NH2</u> group available to form <u>hydrogen bonds</u> with water molecules.
Although there are some potential <u>dispersion forces</u> between the terminal <u>-CH3</u> group of alanine and hexane molecules, we expect the <u>hydrogen bonds</u> between alanine and water to be stronger.
Stronger intermolecular attractive forces between alanine and water lead to a more <u>negative ΔHmix</u> and more <u>negative (smaller positive)</u> ΔHsoln for water than for hexane.
