Receptors that are especially important for helping a person maintain balance are located in the (A) gyrus cinguli (B) inner ear (C) tendons (D) ossicles (E) ligaments

Answers

The receptors that aid in allowing a person to maintain balance are located within the inner ear.

The human ability to walk upright without falling, and a wide variety of other tasks that we perform as all thanks to our ability to maintain balance. This ability is given to us by structures located deep within the inner ear.

The inner ear is located deep within the lateral side of the head. This ear contains 3 semicircular canals or ducts, which are tiny structures filled with liquid. Each of these canals has an expansion at its end known as the ampulla, which holds within it the very small cellular balance receptors called crista.

Birds and insects both have wings, but we do not consider this similarity as evidence of relatedness because ____.

Answers

The wings in birds and insects are not considered as evidence of relatedness because they differ in structures even though their functions may be the same.

Organs in different organisms that are different in structures but similar in functions are referred to as analogous organs. Even though analogous organs serve as evidence of organic evolution, they are indications that organisms differ in the paths taken to evolve.

Some other organs may be similar in structures but different in functions. These types of organs are known as homologous organs and are indications that organisms are kind of related in the path taken to evolve.

Under the hypothesis of blending inheritance, what color(s) would the offspring of a black cat and a white cat be

Answers

Under the hypothesis of blending inheritance, the offspring of a black cat and a white cat would be GREY.  This theory is not now accepted.

Blending inheritance is an erroneous theory from the 19th century that proposed that offspring inherit phenotypic traits as 'average values' observed for such traits in their parents.

Mendel's laws of heredity (i.e., the Law of Segregation and the Law of Independent Assortment) showed that blending inheritance is based on erroneous concepts.

Moreover, incomplete dominance is an inheritance pattern different from blending inheritance because incomplete dominance refers to the observation that in certain traits both gene variants or 'alleles' are expressed in heterozygous individuals.

what are the consequences of either an incomplete or absent ""s"" stage of the cell cycle?

Answers

Answer:

If a cell has not properly copied its chromosomes or there is damage to the DNA, the CDK will not activate the S phase cyclin and the cell will not progress to the G2 phase. The cell will remain in S phase until the chromosomes are properly copied, or the cell will undergo programmed cell death.

Explanation:

The consequences of an incomplete/absent "S" stage in a cell cycle are ;

A programmed cell death The cell will not move to the G2 phase of the cell cycle

The absence or incomplete "s" stage of the cell cycle occurs when the a cell does not completely copy its chromosomes or when there is a significant damage to the genetic material ( DNA ) of the cell. when any of these abnormalities occurs the "s" phase stage of the cell cycle will not be activated until the cell chromosomes are correctly copied. Therefore the cell will not move to the G2 phase of the cell cycle

Hence we can conclude that The consequences of an incomplete/absent "S" stage in a cell cycle are ; A programmed cell death  and The cell will not move to the G2 phase of the cell cycle
