Explanation:
Sickle cell anemia is carried on the recessive allele. Normal is dominant. Mary is a carrier for sickle cell and Mike is normal (but not a carrier).
A. What are the chances of Mary and Mike having a sickle cell child?
B. What are the chances of them having a child who is a carrier?
Answer:
A. 0
B. 1/2 or 50%
Explanation:
Let us assume that the sickle cell anemia trait is represented by s and the alternate normal version by S.
Mary, a carrier would have the genotype Ss.
Mike, a perfectly normal person would have the genotype SS.
If both Mary and Mike marry:
Ss x SS
offspring: SS SS Ss Ss
(A) In order to have sickle cell, the two alleles must be recessive. None of the offspring from the cross has two recessive alleles. Hence, the chances of Mary and Mike having a sickle cell child is zero.
(B) From the cross, two out of four of their potential offspring have the trait in heterozygous condition. Hence, the chances of Mike and Mary having a child who is a carrier is 1/2 or 50%.

Describe steps that can be taken to improve water quality through water conservation
Answer:
While trying to conserve water, we can boil it or purify it through water purifiers so that it may be recycled.
Explanation:
Water can be conserved by:
Turning off the tap when not in use. Check for openings or leaks in water distribution pipes.What is Water Conservation?Water conservation is defined as the practice of using water efficiently to reduce unnecessary water usage. Its conservation is important because fresh clean water is a limited resource as well as expensive. Conservation of this natural resource is important for the environment as well as for us.
We can conserve water by:
Using a dishwasherUsing the right amount of water for each load of laundryChecking the leaks and repair leaksWater the plants wisely, etc.Water conservation means the preservation, control and development of water resources, both surface and groundwater, and prevention of pollution.
Thus, Water can be conserved by:

Which population is most likely to be in Hardy-Weinberg equilibrium?
a large population of ocean fish that lives in an unpolluted ecosystem that has abundant food
a large population of prairie grasses that lives in an ecosystem that is frequently burned by wild fires
a medium-sized population of birds that lives on a chain of islands that have different food sources
a medium-sized population of bacteria that lives on crop plants that are frequently sprayed with pesticides
Answer:
a large population of ocean fish that lives in an unpolluted ecosystem that has abundant food
Explanation:
This is because the Hardy-Weinberg equilibrium states that allele and genotype frequencies in a population will remain constant from generation to generation in the absence of other evolutionary influences. So if the large population of ocean fish isn't being disturbed by the pollution (unpolluted) and they have an abundant source of food they should in Hardy-Weinberg equilibrium since no major changes are happening.

Lower
Higher
Equal
Answer:
higher is the concentration of solute
The liquid having the highest solute concentration. Hypotonic: A solution with a low solute content. Thus, option B is correct.
What concentration of solute (dissolved stuff) than isotonic?When two liquids with varying solute concentrations are compared, the higher solute concentration solution is hypertonic, whereas the lower solute concentration solution is hypotonic. The solute concentration in isotonic solutions is the same.
A solution that has the same concentration as another solution is said to be isotonic.
A solution that contains the same amount of salt as blood and cells. Isotonic solutions are typically used as intravenous fluids in hospitalized patients.
Equal amounts of each solution will flow across a semipermeable membrane separating two solutions. Because the solvent and solute concentrations are the same.
Therefore, higher is the concentration of solute.

Which statement best describes the energy flow as it passes from producers to tertiary consumers?
A. 10% of the energy is transferred through each trophic level.
B. 100% of the energy produced passes to each trophic level.
C. 50% of the energy produced is transferred through each trophic level.
D. 1% of the energy is lost as heat is transferred through each trophic level.
Answer:
The answer is A
Explanation:
At any given trophic level, only 10% of the energy is transmitted to the next level; the remaining 90% is primarily wasted as heat during metabolic activities. Thus, option A is correct.
What is the role of energy flow in an ecosystem?Typically, only 10% of energy is transmitted from one trophic level to the next. This restriction on the number of trophic levels that an ecosystem may support is referred to as “the 10% rule.” organisms that are alive and the energy they hold.
Each trophic level's energy content diminishes as it progresses through an ecosystem.
The 10% Rule states that only 10% of the energy will be transferred when it moves from one trophic level to the next in an ecosystem.

Messenger RNA (mRNA) travels from the nucleus of a eukaryotic cell to the ribosome. At the ribosome, the amino acids are lined up in order as the tRNA molecules line up with complementary bases on the mRNA. This process is called _____ and results in the formation of _____.
Answer:
The correct answer is - translation, polypeptide/amino acid chain.
Explanation:
The translation is the process that involves the movement of mRNA from the nucleus to the ribosome and where amino acids are formed in sequence linked with one another in the same order as the transfer RNA line up with the complementary bases encoded on the messenger RNA or mRNA.
This amino acid chain or the polypeptide folds in a specific way to active protein for the specific function or expression. This process is the last stage or phase of protein synthesis.

Meiosis I involves separation of homologous chromosomes but meiosis II involves separation of chromtids.
Answer:
Meiosis I: in meiosis I there is pair of chromosomes called homologous chromosomes which are to be seperated so one of that two chromosomes right pole of the cell and the second one goes to the left pole so each pole gets a chromosome with two sister chromatids.
Meiosis II: While in meiosis II homologous pair is not formed and single array of chromosomes are arranged to form metaphase plate as formed in Mitosis so, when the spindle fibres contracts each sister chromatids went to their respective poles.
