The protein inside (a) red blood cells that carries oxygen to cells and carbon dioxide to the lungs is (b) hemoglobin. Hemoglobin is made up of four symmetrical subunits and four heme groups. Iron associated with the heme binds oxygen.
Answer:
Explanation:
Cytoplasmic organelles are "little organs" that are suspended in the cytoplasm of the cell. Each type of organelle has a definite structure and a specific role in the function of the cell.
Answer;
D. The Open Marine ecosystem
Explanation;
An ecosystem
is the lowest level of environmental complexity that includes living (biotic factors)and nonliving factors (abiotic factors).
-The Open marine ecosystem contains the fewest photosynthetic producers, this is because most producers can't live or survive in an areas with the lack of nutrients or sun light. They need nutrients for growth and also sunlight to undertake the process of photosynthesis which helps them make their own food.
Cells move to new positions as an embryo establishes its three germ tissue layers during option(d) i.e, gastrulation.
A young developmental process known as gastrulation occurs when an embryo changes from a one-dimensional layer of epithelial cells (blastula) to a multilayered, multidimensional structure known as the gastrula.
The three embryonic germ layers—the endoderm, ectoderm, and mesoderm—are positioned during gastrulation. Later, these layers grow into specific body systems. The three layers of embryonic tissue, or germ layers, are created as a result of gastrulation. These cells will multiply, move, and differentiate during development into the four main tissues: epithelial tissue, connective tissue, muscle tissue, and nerve tissue.

Answer:
The correct answer is- TAAGCCGATAAATGCTAACGGTA.
Explanation:
DNA is a nucleic acid molecule made of two strands. Each strand is made up of nucleotide bonded via phosphodiester bonds. Each nucleotide is made up of- 5C deoxyribose sugar, a phosphate group and nitrogenous bases.
DNA replication produces an exact copy of the DNA molecule through complementary base pairing. The complementary strand is formed by adding nucleotide through DNA polymerase which adds base pairs according to the Chargaff rule. The Chargaff rule states that A will bind T via two hydrogen bonds and G will bind C via three hydrogen bonds.
Therefore, the complementary strand will be-TAAGCCGATAAATGCTAACGGTA
