In which phylum do we first see tissue-level organization?

Sliva [168]

Cnidarians were the first phylum that scientists saw tissue level organization in. Tissue level organization meaning cells all of one type start to function in a unified way.

Delvig [45]

The levels of organisation are

Domain: Eukarya

Kingdom Animalia

Phylum :Chordata

Explanation:

They all share these levels of organisation because;

for the Domain Eukarya, they have;

→multi-cellular cells containing nucleus; and other membrane bound organelle.e.g Mitochondrial.

→their DNA located in the nucleus packaged as linear chromosomes bounded by histone proteins.

→mode of reproduction which is sexual.

They share Kingdom Animalia because;

→they have multi-cellular, specialised cells, bounded by plasma membranes.

→they have specialized tissues, organs, and system.

→they all undergo heterotrophic mode of nutrition as evident in the question 'that they must consume plants and animals as source of energy'

→they exchanged communication by nervous ssytem and 

→ use homeostatic mechanisms to regulate water balance of the body through the kidney.

→Humans,Rabbits,and whales are VIVIPAROUS; they give birth to young ones alive.

→Most fishes lay eggs to reproduce, they are said to be Ovoviviparous.

They belong to phylum Chordata because ;

→they all have noto chord; which serve as template for axial skeleton.

dorsal hollow nerve cord -template for the brain and spinal cord

→pharyngeal slits- templates for gill aches in bony fishes and components of inner ear in land animals.

→ tail length varies in these organisms.

Write a short discussion describing trends in the data: compare the control cups (distilled water) versus the experimental cups

Eva8 [605]

Answer:

The leaf discs only float in bicarbonate solution and in the light environment.

Explanation:

The bicarbonate dissolves in water to produce a source of inorganic CO2 in the reaction:

NaHCO3 + H2O → H2CO3 + OH- + Na+

Then, the HCO3- undergoes fixation through several complex steps in order to form a carbohydrate or sugar. These store the converted solar energy in their bonds as chemical energy to be used in metabolism.

Photosynthesis is a chemical process, essential to plant and other primary producers producing energy. Energy in the form of glucose molecules is derived from solar or light energy, water, and inorganic carbon dioxide, while it releases oxygen (from the light reaction). The leaf discs float as O2 gas is produced, making them buoyant.

6CO2 + 6H20 + (energy) → C6H12O6 + 6O2

Carbon dioxide + water + energy= glucose + oxygen

Explain why an mRNA transcribed from the template strand of the SIRT3 gene in normal stomach ( NS ) cells is translated to produ

Ivanshal [37]

Answer:

Explanation:

The double-stranded DNA molecule has the potential to store genetic information in either strand, although in most organisms only one strand is used to encode any particular gene.

The template strand is the non-coding strand. The coding strand of DNA is the non-template (mRNA-like) strand (see attachment).

Thus, genetic information is expressed by transcription of the non-coding (template) strand of DNA, which produces an mRNA molecule that has the same sequence as the coding strand of DNA. Therefore, if a mRNA is transcribed from the non-template strand, the genetic information will not be contained in that strand and it would not produce a correct protein.
