What are the four most common occurimg chemical elements in organisms​

Biology
1 answer:
ivolga24 [154]3 years ago
6 0

Answer: I would say that the most common elements in living organisms are: 1)Oxygen

2)Carbon

3)Hydrogen

4)Nitrogen

Explanation:

1)Oxygen is the most abundant element contained within the living organisms, composing about 65% of the human body. It is also critical for cellular respiration in all aerobic organisms.

2)Carbon is essential for the survival, growth and reproduction of living things. It is a finite resource that comes in different forms and transfers from living to non-living things in various ways.

3)Hydrogen is important because it is involved in the process of enzyme catalysis and because it stabilizes things like nucleic acids and proteins.

4)Nitrogen is an important part of building amino acids and nucleic acids, both which are critical for maintaining life. Amino acids and nucleic acids are essential building blocks for cellular growth and repair in organisms in the form of protein.

Julie wrote down the list below of the reasons why she thinks that humans should stop relying on fossil fuels.
forsale [732]

Julie listed out fossil fuels are a non-renewable source of energy and Fossil fuels are becoming more expensive.

Option C

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

Fossil fuels are defined as the type of non renewable energy which is formed as a result of dead and decaying organic matter over thousands of years under pressure and temperature of Earth’s core.

This type of fuels are formed due to the dumping of dead prehistoric organisms like dinosaur and others under the soil under a tremendous pressure and very high temperature, where they are acted upon by bacteria and other chemicals to reduce them into petroleum and coal. These are totally non renewable and they are getting expensive over days due to shortage of availability.

If a corn plant was heterozygous for kernel color and seed shape, what would be the genotype of the plant?
NNADVOKAT [17]

Answer:

<em>The genotype of the plant will be PpSs and the phenotype will be purple colour and smooth shaped. </em>

Explanation:

Considering the description in the question, we know that purple colour is dominant over the yellow colour and smooth shape is dominant over the wrinkled shape.

A homozygous trait can be described as a trait which arises due to the same alleles of a gene. A heterozygous trait arises when both the alleles of a gene are different. In such a case, one allele will be dominant over the other one and the phenotype of the dominant allele will be seen in the plant. As purple colour and smooth shape are dominant traits, hence they will be seen in the heterozygous plant.

Plantae: Autotrophic, Multi- or Monocellular, have cell walls as well as a membrane, have a chloroplast making the characteristic green color and to capture sunlight for photosynthesis. Break down generated glucose into it's components.

Animalia: Heterotrophic, Multi- or Monocellular, have a cell membrane made of a phospholipid bilayer, and many mitochondria to aid with movement energy. Feed on plants or other animals. Eukaryotic cells.

Fungi: Heterotrophic, most Multicellular, have a rigid cell wall made of chitin, specialized cells to aid with decomposition of dead organic matter. Eukaryotic cells.

Protista: Can be plant-like, animal-like, or fungus-like. Most are single-celled, may be chemosynthetic or photosynthetic. Eukaryotic cells.

Archeabacteria: Prokaryotic. Do not have nuclei or membrane-bound organelles. Move around using a flagellum to propel itself. Lives in mainly fluid environments (air, water). Separated from Eubacteria due to it's high tolerance of extreme conditions, such as high salinity, no oxygen, burning heat, or freezing cold. Can be chemosynthetic or anaerobic, as well as aerobic.

Eubacteria: Normal, everyday bacteria. Prokaryotic, chemosynthetic, anaerobic, or aerobic. Do not have nuclei or membrane-bound organelles. Mobile using a flagellum to propel itself.
