The genetics of a-thalassemia are similar to narrow sense heritability in that there is a gradation of phenotype, with each alle
ki77a [65]

Answer:

In strict mode, the narrow-sense heritability is the proportion of the additive genetic variance that contributes to the total of the phenotypic variance. This value can be associated with the inheritance of the a-thalassemia .

Explanation:

A-thalassemia is a genetic disorder caused by mutations affecting four different genes that encode alpha-globin, thus affecting the hemoglobin production process and, consequently, oxygen transport. The mode of inheritance of the a-thalassemia may be associated with narrow sense heritability since the phenotype is manifested by gradation, i.e., each allele might contribute in similar mode to this genetic condition.

Answer:

Protista

Explanation:

  1. Firstly, it cannot be bacteria because bacteria is prokaryotic with no membrane bound organelles. And it's cell wall is made of murein (peptidoglycan).
  2. It certainly isn't a virus virus because a virus has no true cellular structure.
  3. Let's see why we ruled out the other 3 eukaryotic kingdoms:
  • It can't be an animal because animal cells don't have cell walls and are multicellular.
  • It can't be fungi because its cell wall is made of chitin, not cellulose.
  • It can't be a plant because plants are all multicellular.

Production of energy using water power

Using electricity or energy-saving products, creation of technology to capture sulfur dioxide are the processes that can be taken into account.

<h3><u>Explanation</u>:</h3>

Acid rain is a very serious issue in the urban areas now a days. Acid rain forms due to the excessive production of gases like sulphur dioxide, nitrogen oxides etc which are beyond the level of absorption by the environment. This gases go up in the atmosphere and they mixes with cloud water to form corresponding sulphuric acid and nitric acid. These acids come along the rain and decrease the pH of the water bodies as well as soil.

If we start using water as the source of our energy production, then we can eliminate the use of coal and other fossil fuels which are chief sources of these gases.

If we can grow some technology to capture these gases before they are released into the environment, then also there will be less problems. Technologies like alkali bath are not so operative in large scales.

We can use electricity in boilers and other places where still, fossil fuels are brunt to produce the heat so that sulphur oxides don't come out.
