Answer:

Photosynthesis. Protists are food producers like plants, they can generate their food by themselves through the process of photosynthesis.

Explanation:

PROTISTS

Protists are eukaryotes that have a nucleus containing their DNA. They possessed membrane-bound organelles, like mitochondria and the endoplasmic reticulum. They are most often than not single-celled, though some are multicellular. The protist kingdom is so diverse because their ways of getting food and reproducing vary widely. They require a moist environment to live so most are aquatic. They can be found in lakes, ocean or damp soil. Some live in or on other organisms while others are free-living. Some protists are more closely related to plants or animals than they are to other protists. Protists are re unicellular as opposed to multicellular plants. Plants are complex and big while protists are microscopic. They are also capable of movement which plants cannot. Protists have complex life cycles. Many have both asexual and sexual reproduction. Examples of protest are; Spirogyra, Euglena, Amoeba, and Paramecium.

Protists can get their food in different ways. They may ingest or engulf smaller particles like bacteria. This is achieved by extending its cell wall around the food item to form vacuole. They may absorb food molecules across their cell wall by process of diffusion. Finally, they can generate their food use in light via photosynthesis.

This process of photosynthesis in which they can generate food like plants makes them suitable for point X in the diagram showing the branches tree for four kingdoms.

As DNA replication begins the DNA molecule is broken apart into two ________ strands.

Serjik [45]

As DNA replication begins the DNA molecule is broken apart into two complementary strands. DNA replication is the process by which DNA makes a copy of itself during cell division. The process occurs in all living and is the basis for biological inheritance. The process starts with the separation of DNA strands in the double helix. Then replication for is formed followed by the binding of bases to each strand. Then the last step is termination of the Replication process

5. Nucleus

6. mRNA

7. Cytoplasm

8. Ribosome

10. anti-codons

11. codon

12. amino acids

13. protein

Explanation:

Deoxyribonucleic acid or DNA hold all the instructions that make up an organism. It determines the physical structure and even the function of the different cells that make up all organisms.

The DNA are all stored in the NUCLEUS of cells. Typically, eukaryotic cells have a nucleus except red blood cells. The nucleus has a nuclear envelope that keeps the DNA stored inside but it has nuclear pores that allows it to interact with the cytoplasm.

In order for DNA to be replicated, it needs to be turned into messenger RNA, otherwise known as mRNA. The mRNA decodes the DNA in order for the cell to use the code. The process is called transcription.

Transcription is done within the nucleus. Before the cell can understand what to do with DNA, mRNA transcribes to know what information it needs to produce specidic proteins.

Once transcription is done, it will then bring the information out of the nucleus and into the cytoplasm. The cytoplasm is the viscous gel-like solution that holds the organelles of the cell. In the cytoplasm you have ribsomes.

Ribosomes is where protein synthesis takes place, this is why it is called the protein factory of the cell. It is a molecule that is made up of ribosomal RNA, which direct the chemical processes involved in protein synthesis. For protein synthesis to happen, it will need another type of RNA, which is the tRNA.

tRNA is transfer RNA and they translate the mRNA sequence into proteins. tRNA have amino acids attached to it.

Each 3 bases of the mRNA are collectively known as codons. These codons correspond with specific tRNA that hold the anticodons. These anticodons code for specific amino acids that they also hold.

When they pair up, the tRNA drop off the amino acid which form a chain with the other tRNA amino acids that complete the code. These chain of monomers then make the protein specific to the DNA code that was copied in the beginning.
