Proteins

Proteins is the most thermogenic of all nutrients and macromolecules we eat. Thermogenesis is the generation of due to digestion and metabolism of food. Studies shows that proteins tend to be more thermogenic that carbohydrates and fats. This means that the calorie given of by proteins is converted and released as heat and less available for storage. This means that the stored energy formed from protein much of it is released as heat and unlike other macromolecules few of it is converted to a energy that can be stored.

Which statement best summarizes "Save the Coral Reefs”?Coral reefs are a very important component of the ocean’s ecosystem becau

cupoosta [38]

Answer;

-Coral reefs are a very important component of the ocean’s ecosystem because they support sea life, such as crabs and sea turtles. In fact, over four thousand species depend on the survival of the reefs, which are being destroyed by bleaching. More must be done immediately to save the reefs.

Explanation;

-Coral reefs are important for many different reasons aside from supposedly containing the most diverse ecosystems on the planet.

-They protect coastlines from the damaging effects of wave action and tropical storms ( they provide a buffer, protecting our coasts from waves, storms, and floods, helping to prevent loss of life, property damage, and erosion) and also provide habitats and shelter for many marine organisms.

Cell Division Homework #1 Introduction to Cell Division Directions: Compare and contrast the following pairs of terms:

wel

Answer:

Sister chromatids / centromeres: When a single chromosome has been replicated in copies, each copy is called a sister chromatids.

A special part of the chromosome called the centromere holds the two sister chromatids together. A centromere is like a built-in rubber band for two sister chromosomes.

Mother cell / daughter cell: identical.

Daughter cells are genetically identical to the mother cell at the stage of production through mitosis.

On the other hand, at the stage of production through meiosis, the daughter cells are genetically different and contain only half of the genetic material of the mother cell.

Interphase / cell division: A cell spends most of its time in what is called interphase, and during this time it grows,

replicates its chromosomes, and prepare for cell division.

The cell then leaves Interphase, undergoes mitosis, and completes its division.

DNA / chromosome: Genes are segments of deoxyirbonucleic acid (DNA) that contain the code for specific protein that functions in one or more types of cell in the body

Chromosomes are structures within cells that contains a person's genes. Genes are contained in chromosomes, which are in the cell nucleus.

Mitosis / cytokinesis: Basically, mitosis is a process by which the duplicated genome in a cell is separated into halves that are identical in nature.

Cytokinesis is the process where the cytoplasm of the cell divides to form two 'daughter' cells. The result is the formation of two 'daughter cells', each having a nucleus.
