Over-arching theories are so important because they help scientists choose their methods of study and mode of reasoning, connect

important phenomena in new ways, and open new areas of study.
Biology
1 answer:
Igoryamba3 years ago
5 0

Answer:

True

Explanation:

Over-arching theories are designed to clarify, predict and interpret events and, in many situations, to question and broaden current understanding beyond the boundaries of basic boundary assumptions. The theoretical context presents and outlines the hypothesis that demonstrates why there is an area for research undergoing analysis.

Where do you think magna comes from?
Softa [21]

Answer:

Magma is primarily a very hot liquid, which is called a 'melt. ' It is formed from the melting of rocks in the earth's lithosphere, which is the outermost shell of the earth made of the earth's crust and upper part of the mantle, and the asthenosphere, which is the layer below the lithosphere.

Sodium and potassium ions move in and out of the axon when the membrane is ______
Ostrovityanka [42]

Answer:

Answer : Depolarized

Explanation:

Sodium and Potassium ions tend to move inside of the axin when the membrane is depolarized.

A change in polarity occurs in the axon membrane when a nerve impulse travels across it.  At the beginning of an action potential or nerve impulse , the ions of sodium tend to move inside of axon causing depolarization. As a result potassium ions tend to move outside of the axon causing re polarization. Hence, this effect causes the nerve impulse to travel in one direction only inside the axon.

Explain incomplete dominance, using snapdragon<br> flowers as an example.
oee [108]

Answer:

Dominant allele does not completely conceal recessive allele.

Snapdragon with genotype Rr (R being red and r being white), would have a phenotype of pink flowers.

Explanation:

Incomplete dominance is where a dominant allele is not able to completely conceal a recessive allele, usually leading to a phenotype which appears to be a combination of the two.

For example, in snapdragons:

The allele for red flowers (R) is dominant over the allele for white flowers (r). Let's say a snapdragon flower had the genotype Rr, one allele for red flowers and one for white. In the case of 'normal' dominance the dominant red flower allele (R) would mask the effects of the recessive white flower allele (r), resulting in the phenotype (outward observable characteristics) of having red flowers.

However here in the case of incomplete dominance, the dominant allele would not be able to fully cover up the effects of the white flower allele, meaning that both colors (red and white) are expressed in the phenotype, resulting in pink flowers.

Hope this helped!

A newborn baby dies soon after birth because her diaphragm and rib cage muscles failed to contract and she was unable to breathe
kozerog [31]

Answer:

Troponin

Explanation:

This is a complex of three proteins  (Trop C, I, T) that are responsible for muscle contraction of  the skeletal and cardiac  muscles . its binds with protein tropomysin  to lie in the grove between the actin filaments.  its prevents contraction by blocking  myosin crossbridge  in a relax muscles.Inorder to aid contractions  calcium ions binds with troponin, which leads to confrontational change.This exposes myosin on actin filaments,  leading to formation of crossbridge and therefore contraction of muscles.

Therefore if there is  a mutation in the gene that encoded Troponin, as explained above, calcium ion  will not be able to bind with tropinin, and there will be no exposure of myosin on actin filaments, no binding of  myosin on actin to cause crossbridge, and consequently no  muscle contraction,

Thus the intercoastal  muscle and diaphragm will not contract leading to death of the baby.
