The foxglove plant, seen in the illustration, produces very toxic chemicals that can cause serious illness and death in any orga

nisms that eats the plant. Why do scientists think the foxglove plant evolved such powerful poisons?
A) The poisons function to kill invading bacteria and other pathogens that may harm the plant.
B) The poisons maximize the efficiency of the photosynthetic process, allowing the plant to make more food.
C) The poisons discourage any animal from eating the plant, preventing damage to the plant from herbivores.
D) Poisons are likely to be the product of genetic mutations in the DNA of the plant and do not have any useful function.

Answer:

C

Explanation:

Scientists believe that the poisons discourage any animal from eating the plant, preventing damage to the plant from herbivores. Foxglove plants evolved to produce the toxic chemicals as a means of defense against animals that may eat the plant.

olchik [2.2K]

Answer:

Animal ; prokaryote ; plant ; virus

Explanation:

Animal:  An animal cell possesses cell membrane, ribosomes, lysosomes and nuclear membrane.

Prokaryote:  In a prokaryotic cell, cell wall is present  such as bacteria, ribosomes are present  but nuclear membrane is absent

Plant: A plant cell possesses cell wall, ribosomes, nucleus and a large vacuole.  

Virus:  Viruses reproduces inside a cell  because they do not have their own energy producing system, nucleus is absent  but nucleic acid ( DNA or RNA) is present

Check all the functions that take place within the eukaryotic cytoplasm.
sesenic [268]

The cytoplasm is a fluid substance that fills every living cell which is enclosed by the cell membrane. This substance is mainly composed of water and proteins.

The functions that take place within the eukaryotic cytoplasm are diverse:

  • Location for most metabolic pathways. Except for the metabolic pahtways in cell nucleus and cytoplasmatic organelles, all metabolic functions (e.g., synthesis of biomolecules, growth, etc) occur in the cytoplasm.  The cytoplasm contain enzymes (i.e., proteins) to carry out different chemical reactions.

  • Location for organelles that house many of the metabolic pathways for the cell. For example, the synthesis of ATP (the energy coin of the cells) is carried out in the mitochondria, which are organelles found in the cytoplasm.

  • Location for the cytoskeleton that gives integrity to the cell. The cytoplasm contains all of the three types of filaments of the cytoskeleton (i.e., microtubules, actin filaments, and intermediate filaments) which provides structural support to the cells.

On the other hand, in plant cells, the cell wall is located outside the cell membrane.

What is the term for the nucleotide sequences that are removed during mrna processing?
Ne4ueva [31]

The correct answer is: introns

Processing of mRNA is process that occurs only in eukaryotic cells. After the transcription, newly formed mRNA molecule is called and it must be processed into a messenger RNA (mRNA). Processing includes:

• Addition of a 5' cap to the beginning of the RNA

• Polyadenilation- addition of a poly-A tail (tail of A nucleotides) to the end of the RNA

• Splicing- removal of introns and linking the exons

After these steps mRNA is mature and used for the further steps (e.g. translation).

Sometimes some genes are alternatively spliced.
