Nutka1998 [239]

Answer:

The effect might be due to the gene expression.

Explanation:

The effect might be due to the variation in the gene expression in the organism. In this way, the variety of the genetic pool is likely to result in a diversity of the gene pool or genome. Because of the mutation and the environmental factors, there is likely to be a slight variation of the species. This results in a slight difference in the phenotypic expression.

Which type of macromolecule combines with proteins to make compounds such as peptidoglycan and other types of identifying compou
mrs_skeptik [129]

Answer:

Answered below

Explanation:

Pepetidoglycans are the structural polymers which make up the cell walls of most bacteria.

It consists of the macromolecule, glycan chains, which are repeating N-acetylmuramic acid and N-acetylglucosamine residues. These glycan chains combine or cross-link with peptide side chains (proteins) to form a mesh-like layer outside the plasma membrane of most bacteria.

Peptidoglycan is the major structural component and the basic unit of the bacterial cell wall and provides protection to the cytoplasmic membrane, mechanical rigidity and also regulates the passage of fluid, amino acids, sugar and ions, in and out of the cell.

Word bank: (Thermosphere) (Aurora boreal is) ( Large-scale air turbulence and mixing at this layer) ( Stratosphere) (The coldest
Lyrx [107]
  • Thermosphere - Fourth layer of Earth's atmosphere.
  • Aurora Borealis - Ionosphere layer of thermosphere.
  • Large-scale air turbulence and mixing at this layer - Troposphere
  • Stratosphere - Second lowest layer of Earth's atmosphere. No Air turbulence so airplanes fly in this layer.
  • The coldest temperatures in the atmosphere occur at the junction- of Stratosphere and mesosphere
  • Maximum ozone - Ozone layer in Stratosphere

Explanation:

Atmosphere is formed by mixing of gases. The layers of atmosphere is given below.

1. Troposphere -

  • The first layer of the atmosphere.
  • Weather occurs in this layer.

2.Stratosphere -

  • The second layer of Earth's atmosphere.
  • Contains Ozone layer.

3. Mesosphere -

  • The third layer above the stratosphere.
  • Coldest layer.

4. Thermosphere -

  • The fourth layer of the atmosphere.
  • Warmest layer.
  • Ionosphere - lowest level of thermosphere above mesosphere.
  • Aurora Borealis, Northern and Southern lights are seen in this layer.
  • Exosphere - outermost layer of thermosphere.
  • Satellites are in this layer.
  • Outer space with no gravity.

Which body systems interact to regulate blood pressure?​
Paha777 [63]

Answer:

In addition to the local control of blood flow, global control of blood flow including changes in cardiac output and control of arterial BP is mediated by the autonomic nervous system. Global neural control of arterial hypertension is essentially through the sympathetic nervous system (SNS).
