They have a lot of applications in our body, For example

Carbohydrates.-It is so important for the body because they are nutrients that provide energy

Nucleic Acids.-It is essential for all known forms of life because it inherits Genetic factors.

Answer & Explanation:

Carbohydrates - They are used primarily by the body as a source of energy through the breakdown of <u>glucose</u> molecules.

Lipids - They act as an energy reserve, just as carbohydrates are precursors of various hormones, as well as acting as thermal insulators and carriers of fat-soluble nutrients and vitamins.

Proteins - Acting in building muscle tissue and maintaining physiological and metabolic functions. Proteins contain essential amino acids (which are <u>not</u> produced by the human body, and therefore must be consumed in the diet). They are also important in the composition of hormones, antibodies, oxygen transport and blood clotting.

Nucleic Acids - They are responsible for the storage and transport of genetic information and its translation, allowing the synthesis of proteins, which will be able to express the characteristics of each living being.

Match the following.
valkas [14]

Answer:

1 . The stage on the first meiotic division when the homologous chromosomes move to opposite poles but the sister chromatids remain together

: b. Anaphase I

2 . The stage in the second meiotic division where sister chromatids migrate to opposite poles

: c. Anaphase II

3 . A structure on the chromosome that holds a pair of chromatids together during replication

: f. centromere

4 . A double-stranded chromosome following replication attached by a centromere

: d. chromatid

5 . A condition where non-sister chromatid of homologous chromosomes exchange genes

: e. crossing over

6 . The stage in the first meiotic division where the homologous chromosomes line up as a pair

: a. Metaphase I

7 . The stage in the second meiotic division where the chromatid pair lines up at the equator of the cell: g. Metaphase II

Explanation:

DNA replication occurs during the S phase of the interphase of the cell cycle. The replicated DNA molecules are accommodated in two sister chromatids of a chromosome that are held together by a centromere.  

During prophase I, the chromatids of a homologous chromosome pair exchange a genetic segment. This process is called crossing over. It generates recombinant chromatids with new combinations of genes.

Metaphase I of meiosis I includes the alignment of homologous pairs of chromosomes at the cell's equator. This is followed by separation and movement of homologous chromosomes to the opposite poles of the cell during anaphase I.  

Metaphase II of meiosis II includes the alignment of individual chromosomes, each with two sister chromatids, on the cell's equator. During anaphase II, splitting centromere separates the sister chromatids which then move to the opposite poles of the cell.

What were two consequences of the French and Indian War? Include the Proclamation
34kurt

Answer:

1. The French and Indian War began in 1754 and ended with the Treaty of Paris in 1763. The war provided Great Britain enormous territorial gains in North America, but disputes over subsequent frontier policy and paying the war's expenses led to colonial discontent, and ultimately to the American revolution.

2. In the long-term, the Revolution would also have significant effects on the lives of slaves and free blacks as well as the institution of slavery itself. It also affected Native Americans by opening up western settlement and creating governments hostile to their territorial claims.
