Answer;
-Macro evolution
Over millions of years, birds developed as a species. This relates to macro evolution.
Explanation;
-Macroevolution refers to evolution of groups larger than an individual species. Macroevolution encompasses the grandest trends and transformations in evolution, such as the origin of mammals and the radiation of flowering plants.
-The basic evolutionary mechanisms include; mutation, migration, genetic drift, and natural selection; and can produce major evolutionary change if given enough time.
B: amino acids; saccharides
C: amino acids; nucleotides
D: nucleotides; amino acids
Proteins are made up of building blocks known as amino acids, while nucleic acids are made up of building blocks known as nucleotides.
The building blocks of proteins and nucleic acids are fundamental concepts in the field of biology, specifically biochemistry. The building blocks of proteins are amino acids, which are organic compounds made of carbon, hydrogen, nitrogen, and in some cases, sulfur. Proteins comprise twenty different types of amino acids that combine in various ways to fulfill the many functions proteins play in the body.
Meanwhile, the building blocks of nucleic acids are nucleotides. Nucleotides consist of three components: a sugar molecule, a phosphate group, and a nitrogenous base. The two types of nucleic acids, deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), are polynucleotides - chains of nucleotides.
Therefore, the correct answer to the question is C: amino acids; nucleotides.

The structure that helps in the production, processing and transportation of protein within cells is endoplasmic reticulum. This cell organelle has ribosomes attached to it. These ribosomes attached on endoplasmic reticulum are responsible for the synthesis of polypeptides which is further modified. Endoplasmic reticulum is made up of cisternae, vesicles and tubules. Cisternae help in the processing of protein that is protein modification. The vesicles transport the protein to Golgi apparatus. There are many functions of Endoplasmic reticulum but the main function is to produce process and transport protein.

C. Polygenic traits
Answer:A. Codominance
Explanation:
This is a type of genetic inheritance where neither of the genes is dominant over another. Thus both pair of the gene are expressed on the same LOCUS equally with none masking another. Therefore an individual receive both allele of a heterozygous gene, and have equal phenotypic expression
An example is the AB blood group in man, where both allele present on the same locus are fully expressed with no one dominant over another.
Incomplete dominance refers to a blend of alleles where one does not have full dominance over another another, therefore gives a new phenotypic expression different from both alleles.
e.g pink flower allele in four o'clock flower.
Codominance is the non-Mendelian inheritance pattern where both traits are dominant and appear in the organism without one being masked.
The non-Mendelian inheritance pattern that states that both traits are dominant and both appear in the organism, and neither trait is masked is called codominance.

Answer: That is false
Explanation: Catfishing is a deceptive activity where a person creates a fake identity on a social network account.
Answer:
A. In a stable ecosystem, life forms have enough food for energy and they are not wasting that energy trying to adapt t their environment. This gives them added opportunities to grow and reproduce. A stable ecosystem can extend its boundaries and interact with an adjoining ecosystem which could benefit both ecosystems.
