red-green color blindness is an x-linked recessive disorder. if the mother is RGCB and the father has normal vision, what are the changes for daughters and sons to hae the trait
Answer:
The correct answer would be -
RGCB daughter - 0%
RGCB sons - 100%
Explanation:
Red-green color blindness is a sex-linked recessive disease that means it will only express in absence of the normal allele that is present on X-chromosomes. As it is known that males have only one X-chromosomes therefore, the chances are more in males to be affected in presence of the recessive gene. In this given case women s RGCB and man has normal vision. The genotype of women would be both recessive alleles XcXc and genotype of man would be XY.
The gametes would be - Xc, Xc and X, Y
then the cross:
Xc Xc
X XXc XXc
Y XcY XcY
so the offspring would be -
Carrier female = XXc (50% chance in total and 100% in daughters)
RGCB daughters = 0%
RGCB male = XcY (100% in sons and 50% of total children)

Explain what causes a muscle to go into rigor mortis. Your answer should include the circumstances which cause it, as well as why those circumstances cause the effect (what is happening in the muscle at a molecular level which causes the stiffness).
Explanation:
Rigor mortis develops as the body's energy source (adenosine triphosphate [ATP]) is depleted. Muscle fibers require ATP for relaxation; once depleted, actin and myosin proteins remain complexed, resulting in stiffening of the muscles..

Which best represents a balanced equation
Answer:
option C is correct answer of this question
hope it helps
it is balanced equation
The example of a balanced chemical equation is 2H₂ + O₂ → 2H₂O. Thus, the correct option is C.
What is a balanced equation?A chemical equation is the symbolic representation of the chemical reaction in the form of symbols and chemical formulas such as H₂O. Chemical equation are generally are unbalanced however, these reactions can be balanced.
Balancing a chemical equation refers to balancing the stoichiometric coefficients on both the reactants and products side of the reaction which is because the chemical equation must obey the law of conservation of mass of the atoms.
2H₂ + O₂ → 2H₂O
This reaction has 4 H and 2 O atoms.
Therefore, the correct option is C.

small crystals
cooled quickly
produced from magma
formed at Earth’s surface
Answer:
C. produced from magma.
D. formed at Earth’s surface
Explanation:
Earth crust refers to the outermost layer or thin shell which makes up the earth such as sedimentary, metamorphic and igneous rocks.
The Earth crust is typically made up of two (2) main types;
1. Oceanic crust: this crust has a thickness ranging from 5 km to 10 km and comprises of denser rocks such as diabase, gabbro and basalt.
2. Continental crust: this crust has a thickness ranging from 30 km to 60 km and comprises of minerals such as quartz, silicate, feldspar, aluminum and less dense rocks such as granite
An igneous rock has a coarse texture and is dark in color. Also, an igneous rock can be accurately described as being produced from magma and formed at Earth’s surface.

C. Whether the virus has a protein capsid
D. Whether the virus is helical, icosahedral, enveloped, or complex
Answer:
A is the answer i had same answer
The information is necessary to understand how a virus produces the proteins it requires is " whether the virus is in the lytic or lysogenic cycle".
What is virus ?A virus would be an infectious submicroscopic creature that only reproduces inside of live cells. All living things, including plants, animals, even microbes like bacteria or archaea, are susceptible to virus infection.
What is lysogenic cycle?The bacteriophage nucleic acid is integrated into the genome of the bacterial host during lysogeny or a spherical replicon forms in the bacterial cytoplasm.
Therefore, the information is necessary to understand how a virus produces the proteins it requires is " Whether the virus is in the lytic or lysogenic cycle".

The concept of induced fit refers to the fact that a. Substrate binding may induce a conformational change in the enzyme, which them brings catalytic groups into proper orientation. b. When enzymes bind substrates, the substrates are bought into proximity to make a chemical reaction favorable. c. When a substrate binds to an enzyme, the enzyme induces a loss of water from the substrate. d. When a substrate binds to an enzyme, free energy is released due to non-covalent interactions.
Answer:
Option A, Substrate binding may induce a conformational change in the enzyme, which them brings catalytic groups into proper orientation.
Explanation:
Induced fit concept refers to introduction of continuous change of enzyme conformation on substrate binding. This change in the shape of enzyme either inhibit or enhance the activity of enzyme. This makes the enzyme catalytic and hence lower the activation energy thereby increasing rate of reaction.

Explain how the genetic disease called Sickle Cell Anemia is more prevalent in African- Americans compared to other races because of the Malaria Disease.
Answer:
Explanation:
This is because sickle cell disease is common in malaria dorminated area because their traits confers resistance to malaria. The red blood cells, which contain abnormal hemoglobin become sickle in shape after it has been affected by malaria parasite. Therefore, most American that have African ancestry are at high risk of
the disease because the African ancestry are carriers if this gene and are inherited by the Americans.

how is spark formed, and why might a spark start an explosion?
Answer:When the applied electric field exceeds the dielectric breakdown strength of the intervening medium, a spark is generated. In a mechanism known as dielectric breakdown, the exponentially increasing electrons and ions allow regions of the air in the gap to become electrically conductive.
An electrostatic spark causes the blast. The sudden rise in temperature that occurs as the mixture ignites causes a massive increase in gas pressure. The ensuing increase in pressure could collapse the chamber with a noisy explosion if the burning vapour were to be trapped.

How does gene regulation relate to organism complexity?
Answer:
Organisms that are more complex, such as eukaryotes, have cells that are specialized for specific functions. Gene regulation needs to be more complex to produce these specialized cells for complex organisms.
Hope this helps!
More complex organisms such as eukaryotes have cells that are specialized for specific functions where gene regulation needs to be more complex for complex organisms to produce these specialized cells.
What is Gene regulation?The process of turning genes on and off, defined as gene regulation which is an important part of normal development. For example, genes turn on and off in different patterns during development to make a brain cell look and function differently than a liver cell or a muscle cell.
Gene expression is controlled at two levels which is transcription which is controlled by limiting the amount of mRNA that can be produced from a particular gene and the second control is through post-transcriptional events which allow the translation of mRNA into protein.
Thus, more complex organisms such as eukaryotes have cells that are specialized for specific functions where gene regulation needs to be more complex for complex organisms to produce these specialized cells.
