The process of breaking up molecules into their component parts is:
liubo4ka [24]

The correct answer is ionization.

Ionization refers to the procedure by which a molecule or an atom attains a negative or positive charge by losing or gaining electrons to produce ions, usually in combination with other chemical modifications.

Ionization can result due to the loss of an electron after collisions with other atoms, subatomic particles, molecules, and ions, or through the association with electromagnetic radiation.

When do the people living in houses on the edge of the ecosystem spray general purpose insecticide to kill a wide rangeOf insect
Katen [24]

The manila grasshopper has several benefits to ecosystem and humans.

  • In general it facilitates decomposition and regrowth of plants by creating a balance between the types of plants that grow well.
  • Like other animals, grasshopper eats and excretes in the soil. Its waste increases the fertility of the soil and promotes plant growth.
  • Grasshopper body is rich in protein, on its death microorganisms break down its body and enrich the soil and helps plants to grow.
  • Grasshoppers prevent over growth of plants as it consume about 10% of the available plant biomass, thus maintain ecological balance.

Bas_tet [7]

The Ras protein found in tumors usually cause which of the following events to occur excessive cell division.

<h3>How does Ras oncogene contribute to cancer?</h3>

Ras genes codes for proteins that can drive cancer when mutated.

All Ras proteins are GTPases which work as molecular regulators in the cell, controlling signaling pathways and other interactions.

Thus, option "A" is correct.

A new kind of tulip is produced that develops only purple or pink flowers. Assume that flower color is controlled by a single-ge
Sophie [7]

Answer:

a. purple allele (C) = 0.609, pink allele (c) = 0.391

b. purple homozygotes = 371, pink homozygotes = 153, heterozygotes = 476

Explanation:

Given -

Purple flowers - 847

Pink flowers - 153

The frequency of recessive genotype i.e

q^ 2 = \frac{153}{1000} \\q^ 2 = 0.153\\

Frequency of recessive allele i.e q is equal to

q = \sqrt{0.153} \\q = 0.391

As per hardy Weinberg's first equilibrium equation -

p + q = 1\\p = 1-q\\p = 1-0.391\\p = 0.609

Frequency of purple homozygous species

= p^2\\= 0.609^2\\= 0.371

Number of purple homozygous species = 0.371 * 1000= 371

Number of pink homozygous species = 0.153 * 1000= 153

Heterozygous species is equal to

(1-0.371-0.153)* 1000\\= 0.476 * 1000\\= 476
