Answer:
DNA helicase separates the two strands of DNA at a replication fork.
Explanation:
To allow DNA replication, two DNA strands should be separated to serve as a template strand. DNA helicases are the enzymes that separate the two parental DNA strands in an energy-dependent way. DNA helicases move along the DNA and separate the two strands by breaking the hydrogen bonds between the complementary base pairs of two DNA strands. The energy released from ATP hydrolysis is used to break the hydrogen bonds.
Answer:
It has an anterior and posterior face. The greater tubercle serves as attachment site for three of the rotator cuff muscles – supraspinatus, infraspinatus and teres minor – they attach to superior, middle and inferior facets respectively. The lesser tubercle is much smaller, and more medially located on the bone
Answer:
Claim 5: Cells need glucose AND oxygen to release energy.
Explanation:
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.
A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
Cellular respiration can be defined as a series of metabolic reactions that typically occur in cells so as to produce energy in the form of adenosine triphosphate (ATP). During cellular respiration, high energy intermediates are created that can then be oxidized to make adenosine triphosphate (ATP). Therefore, the intermediary products are produced at the glycolysis and citric acid cycle stage through the breathing of oxygen used to obtain energy from the food ingested.
Hence, cells need glucose and oxygen to release energy.
I believe the answer to this question is (D) habitat fragment. Habitat fragmentation is the process in which the loss of habitat causes a division in a larger habitat, resulting in smaller areas that are isolated from each other. In this the tigers are separated from other inhabitable nearby areas.
phenotype
This has to do with looks of an organism
genotype
refers to the genes carried on by its parents.
