Answer:

The bicondylar angle positions the center of mass above the base of support during the single-support phase of bipedal locomotion.

A. True

Explanation:

The bicondylar angle is the functional angle between the diaphysis of the femur, perpendicular to the intercondylar plane.  Very unique to humans, this angle places the knee and the foot under the body's center of gravity during a single support phase of locomotion or gait.  With hip joints set lateral to the body's midline, the bicondylar angle aligns the lower limb with the center of gravity, thereby facilitating human movement.

If you were rolling dice in a casino and observed results comparable to those observed in Part 2, would you assume the dice were
Brilliant_brown [7]

Answer:

Yes, I would guess that the dice are faulty or rigged.

Explanation:

Yes, I would guess that the dice are faulty or rigged.

This is because the chi-square analysis indicates that there is a less than 5% probability that the difference between the expected and observed results were due to pure chance.

Whether during mitosis or meiosis, sister chromatids are held together by proteins referred to as cohesions. Such molecules must
scoundrel [369]

Answer:

1. They must be removed before sister chromatids or homologous chromosomes can separate

Explanation:

During the S-phase of the cell cycle, not only does DNA have to be replicated, but also newly synthesized DNA molecules have to be connected with each other. This replicated DNA (sister chromatids) remain physically connected with each other from S phase until metaphase. This physical connection is called Sister chromatids cohesion.

Sister chromatid cohesion depends on COHESIN, a tripartite protein complex that forms a ring structure to hold sister chromatids together during mitosis and meiosis. Cohesin regulates the separation of sister chromatids during cell division, either mitosis or meiosis. This sister chromatid cohesion is essential for the biorientation of chromosomes on the mitotic or meiotic metaphase spindle, and is thus an essential prerequisite for chromosome segregation. Without the cohesion, sister chromatids would not be segregated symmetrically between the forming daughter cells, resulting in aneuploidy.

Cohesion is established during S-phase of DNA replication, and the cohesins hold the sister chromatid together after DNA replication until anaphase when the removal of cohesin leads to separation of sister chromatids (meiosis II and mitosis) and homologous chromosomes (meiosis I).

The first commercial application of genetic engineering was the use of bacteria to make insulin, a medicine needed by diabetics.
Murljashka [212]

Answer:

The question is incomplete, it lacks options. The options are:

A) It has made the demand for insulin decrease.

B) It has made the incidence of diabetes decrease.

C) It has made it easier for diabetics to inject themselves with insulin.

D) It has made insulin cheaper and more readily available.

The answer is D

Explanation:

Genetic engineering is a biotechnological procedure that involves the transfer of genes from one organism to another using biotechnology. In this case, bacteria cells are said to be genetically modified because their genetic content is tampered with and the genes that produces the insulin protein in humans is added into their genome. Hence, they transcribe and translate this gene to produce the protein-insulin.

Diabetic patients cannot produce this insulin in their system. Hence, the insulin produced from this genetically modified bacteria cells can be administered to diabetics via injection. This genetically modified way of producing insulin has proven to be a far better option to the previous practice of slaughtering cattles and pigs to obtain this protein because the GM method allows insulin to be produced in large amounts making it available and cheaper to diabetics.
