What are linked genes?
kumpel [21]

Answer:

Genes lying close to each other on chromosome

Explanation:

When genes lie close to each other on chromosome,  they are inherited together as an intact unit in meiosis cell division and such genes are termed as linked genes.During meiosis the genetic material (allele/genes) is exchanged between the homologous parent chromosome which causes  chromosome recombination and thus the formation of linkages These genes have high chances of recombination as they lie close to each other.

In direct calorimetry, a person is placed in a large, water-insulated chamber. The chamber is kept at a constant temperature. Wh
Anastaziya [24]

Answer:

Although direct calorimetry is considered to be the most precise technique for the measurement of metabolic rate, construction of such a chamber that is large enough for doing exercise physiology research (or any research for that matter) is extremely expensive and not at all mobile.

Explanation:

Direct calorimetry measures the heat production of an individual, in calories, when placed in an insulated chamber where the heat is transferred to surrounding water. This is a very accurate method of measuring energy expenditure.

g Choose the correct answer from the list. Group of answer choices DNA sequences that are deduced by comparing many related DNA
REY [17]

Answer:

Explanation:

Group of answer choices DNA sequences that are deduced by comparing many related DNA sequences are called CONSENSUS. Unlike DNA synthesis, RNA synthesis requires TRANSCRIPTION. PROMOTERS direct RNA polymerase to the initiation site. RNA synthesis complexes containing DNA, RNA, and polymerase perform TRANSLATION. RNA synthesis (tRNA, mRNA, and rRNA) takes place in complexes containing DNA, RNA, and polymerase are called TRANSCRIPTION BUBBLES. The expression of beta-galactosidase requires the induction of operons by addition of REPRESSORS.
