Answer:
"the presence in or introduction into the environment of a substance or thing that has harmful or poisonous effects."
To break it down, harmful chemicals and other things go into the air and that is called pollution. I believe that you can also pollute the water when you put items like plastic and such in it.
Explanation:
If a dihybrid F1 plant, self-fertilizes, the F2 progeny will have two types of phenotypes. One would be the dominant trait phenotype for both the alleles, which would be possessed by 3/4th of the population.
Other would be recessive trait phenotype for both the alleles, which would be possessed by 1/4th of the population.
One fourth of the population would be true-breeding for the dominant traits.
Half of the population would be heterozygous for both traits and would have dominant phenotype
Rest one-fourth population would be homozygous for both recessive traits
1.)If ang 1-7 and ACEII levels are increased it will result in heart failure-Angiotensin converting enzyme 2 (ACE2), a homologue of ACE, is a monocarboxypeptidase that converts angiotensin II (Ang II) into angiotensin 1–7 (Ang 1–7) which, by virtue of its actions on the Mas receptor, opposes the molecular and cellular effects of Ang II. ACE2 is widely expressed in cardiomyocytes, cardiofibroblasts, and coronary endothelial cells.
2.) ACE2 and ang 1-7 is thought to be cardio protective because ACE2 and Ang 1–7 have emerged as a key protective pathway against heart failure with reduced and preserved ejection fraction
3.) three strains of coronavirus: SARS-CoV, NL63 and SARS-CoV-2. ACE2 receptors are ubiquitous and widely expressed in the heart, vessels, gut, lung - so yes it would increase the likelihood of being infected
Answer:
When molecules are too large or too charged to cross the plasma membrane by diffusion or osmosis, there are other methods to accomplish their transport into or out of the cell. For example, some proteins in the plasma membrane are known as protein channels and they form a way for large or charged molecules to pass through the membrane.
