Answer:
No fertilization occurs.
Explanation:
No zygote is formed if the the number of chromosomes within the cells did not change or remain the same i.e. diploid because for the production of zygote, half number of chromosomes are required in both male and female sex cells or gametes. If the chromosomes are half in both gametes so they fuse with each other forming zygote having diploid cell so we can conclude that for the happening of fertilization process, half number of chromosomes in gametes is necessary if not, no fertilization occurs.

Why are archaea in a different domain from bacteria?
A. They are multicellular, but bacteria are unicellular.
B. They are thought to have separate paths of evolutionary
development
C. They are able to perform endosymbiosis, but bacteria are not.
D. They have no similar characteristics.
Answer:B
Explanation:
Archaea is in a different domain from bacteria because they are thought to have separate paths of evolutionary development. Therefore, the correct statement is option B.
What are the differences between archaea and bacteria domains?Archaea and bacteria are both prokaryotic organisms, but archaea are more closely related to eukaryotes than bacteria. Archaea have unique lipid membrane and cell wall components that are different in composition than those found in bacteria.
These differences suggest that archaea and bacteria evolved to have separate paths of evolutionary development early in the history of life on Earth and then classified into Archaea and Bacteria domains.
Based on the phylogenetic tree constructed by researchers, the tree has classified life into three domains which are Archaea, Bacteria, and Eukarya These domains are based on their fundamental genetic and biochemical differences.
Therefore, archaea and bacteria are in a different domain because they followed separate paths of evolutionary development.

an example of the mouse's ability to
A. reproduce
B. grow and develop
C. respond to the environment
D. obtain energy
Check Answer
Answer:
C Respond to the environment
A mouse running away from the sound of an owl's wings is responding to the environment.
What are living organisms?
The organism which can breathe, reproduce and have the ability to respond to an environment are some of the characteristics of a living organism.
Reproduction is the ability of an organism which gives similar kinds of organisms. Organisms grow and develop through cell division. Cell division is of two types mitosis and meiosis. Mitosis is an equational division.
The organism can respond to the environment. Mouse running away from the sound of an owl's wing is an ability to respond environment. Different organisms can obtain energy from food sources.
Therefore, A mouse running away from the sound of an owl's wings is responding to the environment.

Answer:RNA code for Amino Acids that make Proteins through the process of translation
Explanation:
During translation, tRNA recognizes the mRNA codons, complements them, and add the correct amino acid to the growing protein. CODON and PROTEIN are the missing words.
--------------------------------------------------------------------------
Protein synthesis
Occurs in two steps. Transcription and translation.
Transcription ⇒ mRNA syntheis
The first step before protein synthesis begins is to synthesize messenger RNA, mRNA.
This is the coping process of the DNA section for the desired protein, and it happens in the nucleus.
Translation:
⇒ Cytoplasm stage
• Translation takes place when the formed mRNA moves to the cytoplasm through the nucleus membrane pores.
• Once in the cytoplasm, mRNA meets a ribosome, which is the primary structure for protein synthesis.
• Ribosomes are organelles composed by the association of proteins with rRNA and tRNA. They can be found in the rough endoplasmic reticulum or floating in the cytosol.
• While the ribosome reads mRNA strain from its 5´ extreme to 3´, tRNA adds the correct amino acids to build the polypeptide.
→ mRNA is composed of different codons.
→ Each codon is a chort sequence of
three nucleotides that codes for one amino acid.
→ When tRNA molecules recognize these
sequencies, they add the correct amino
acid to the growing protein.
⇒ Protein synthesis ends when the proteins passes through the Endoplasmic Reticulum and the Golgi complex for their final folding process.

Explanation:
The drawback or disadvantage associated with the use of light microscopes over electron microscope is its lower magnification power.
LIGHT MICROSCOPE:
Light microscope is a type of microscope in which photons of light is used to view specimens. The light microscope is distinct from the electron microscope being that electron microscope uses beam of electrons instead.
