List the levels of organization from smallest to largest and give an example for each. cell….

1 answer:

5 0

From smallest to largest. That will be
Cell; cheek cell
Tissue; hydra
Organ; heart
System; digestive system
Organism; lion
Tissue is a group of cells, an organ is a group of tissues, a system is a group of organs, an organism is a group of systems
Hope that helped. Have a nice day

Compare and contrast fermentation and cellular respiration (at least 2 similarities and 2 differences explained in detail).

professor190 [17]

They're similar because they're both methods the cell uses to make ATP. ... Fermentation takes place without oxygen (also known as anaerobic), so less ATP is produced from each molecule of glucose. Another difference is that the byproducts of cellular respiration are always water and carbon dioxide.

Scientists discovered that the inner core of Earth is a solid. Explain what evidence supports this thinking. Be sure to include

Leya [2.2K]

Answer:

The inner core is solid because the inner core consists of a lot of pressure and high temperatures. And the more pressure and high temperatures the more dense the substance gets.

Which nitrogenous bases are needed to complete the DNA strand pictured below?

Paul [167]

Explanation:

Template: T, A, C, G

Pairing: T- A, A-T, C-G, G-C

Answer: adenine, thymine, guanine, cytosine

Further explanation:

Nucleic acids are comprised of smaller units called nucleotides and function as storage for the body’s genetic information. These monomers include ribonucleic acid (RNA) or deoxyribonucleic acid (DNA). They differ from other macromolecules since they don’t provide the body with energy. They exist solely to encode and protein synthesis.

Basic makeup: C, H, O, P; they contain phosphate group 5 carbon sugar, these nitrogen bases which may contain single to double bond ring.

DNA stores all of an organism’s genetic information. Its molecules comprise the nitrogenous bases Guanine, Adenine, Cytosine and Thymine. These pair up as base pairs due to their varied structure- largely influenced by the location of N molecule ;

cytosine and thymine are formed from pyrimidines- N at position 1 and 3 of a fused ring;
Guanine and adenine are formed from organic compounds called purines (pyramidines fused to another organic ring of imidazole)
Each base pair contains a purine and pyrimidine joined via hydrogen bonding e.g. A-T & G-C and are called base complements.

In certain combinations, these bases form codons which act as instructions for protein synthesis. Codons are three nucleotide bases encoding an amino acid or signal at the beginning or end of protein synthesis.

In most species, the expression of hox genes is colinear with the anterior to posterior organization of the organism. what does

Elden [556K]

Hox genes, which are members of the homeotic transcription factor family, establish the segment identity of tissues within the embryo and are essential regulators of the body plan along the cranio-caudal axis (also known as the anterior-posterior axis). This means during embryogenesis, these genes expression follows a precise spatial and temporal colinearity pattern from the 3' to the 5' end of each cluster.

This indicates that Hox genes expressed anteriorly in the developing embryo are typically found at the 5′ end of the same genomic area, a phenomenon known as spatial colinearity. In comparison, those expressed posteriorly are typically found at the 3′ end of the Hox cluster.

40,000 people were killed in what became known as the Reign of Napoleon. a. True b. False

storchak [24]

This is obviously false. When we're talking about the 40,000 people who were killed in around this time period, we're talking about the so-called "Reign of Terror" which occured BEFORE Napoleon took over. It happened close to the beginning of the French revolution.
