Based on the properties of the monomers that make up the phospholipid polymer, which of the following best predicts how the two phospholipids are positioned in the cell membrane?
a)The hydrophilic heads will face outward toward the cell’s exterior and inward toward the cell’s interior. The fatty acids will be tail-to-tail in the center of the membrane.
b)The glycerol region in the fatty acid will bend toward the interior of the cell. The choline will bend toward the exterior of the cell.
c)The hydrophobic heads will bind with other hydrophobic heads and turn inward to the center of the membrane. The fatty acids will randomly move, giving the membrane fluidity.
d)One choline will turn inward toward other choline in the bilayer. The fatty acids will be attracted to the choline and form the interior of the membrane.
Answers
Two phospholipids are positioned in the cell membrane ,the hydrophilic heads will face outward toward the cell’s exterior and inward toward the cell’s interior. The fatty acids will be tail-to-tail in the center of the membrane.
A phospholipid generally has a head and a tail. The head of the molecule has a phosphate group and is hydrophilic in nature, it is soluble in water. The tail of the molecule is made up of two fatty acids, which are hydrophobic and do not dissolve in water.
Hence, Two layers of phospholipids where the outer layer has the hydrophilic heads facing toward the outside of the cell and the inner layer have the hydrophobic tails facing toward the inside of the cell.

In 3-5 sentences, Explain 2 problems with the evolutionary belief of
long stable periods of no mutations and short periods of rapid
mutations. Use complete sentences and correct grammar.
Answers
Answer:
Umm I am in 5th Grade sorry
Explanation:
The goal of evolution is to develop an organism that is perfect in every way. Given that we are far from being perfect, one could wonder why evolution would merely end with us.
How do mutations cause evolution?Rapid mutations have the drawback of leaving organisms with underdeveloped body parts from a lack of time.
According to the hypothesis of punctuated equilibrium, evolutionary change is characterized by brief bursts of fast evolution followed by prolonged pauses during which nothing changes.
Evolution requires mutations to take place. Every genetic characteristic in every organism originated from a mutation. A key feature of evolution is differential reproduction, which is how the new genetic variety (allele) spreads.
Therefore, the goal of evolution is to develop an organism but rapid mutations have drawbacks.

which of the physiological parameters in the body are most likely to vary from normal homeostatic levels during heavy exercise? select all that apply.
Answers
Several physiological parameters are likely to vary from normal homeostatic levels during heavy exercise. The parameters that are most likely to vary from normal homeostatic levels during heavy exercise include:
Heart rate.Blood pressure.Respiration rate.Body temperature.Blood glucose levelsThese parameters are likely to vary from normal homeostatic levels because of the increased demand for oxygen and energy by the body during heavy exercise. The increased demand for oxygen and energy requires the body to increase the delivery of oxygen and nutrients to the muscles and other organs. This increased delivery of oxygen and nutrients results in an increase in heart rate, blood pressure, respiration rate, body temperature, and blood glucose levels. This increased demand also results in the release of adrenaline and other hormones that help to increase energy production and improve muscle function.

Explain why opposing anabolic and catabolic pathways must have dfferent ezymes for at least one of the steps.
Answers
Anabolic pathways are the metabolic pathways that build molecules, while catabolic pathways break them down. These two pathways are opposing and require different enzymes for at least one of the steps. This is because the enzymes required for anabolic pathways are not suitable for catabolic pathways and vice versa.
Enzymes are highly specific, and they only catalyze specific reactions, which means that the same enzyme cannot be used for both anabolic and catabolic pathways.
For example, the enzyme hexokinase is used in the anabolic pathway of glucose synthesis, while glucose-6-phosphatase is required for the catabolic pathway of glucose breakdown.
Therefore, the opposing pathways need different enzymes to catalyze the specific reactions involved in each pathway.
To explain why opposing anabolic and catabolic pathways must have different enzymes for at least one of the steps:
Anabolic pathways involve the synthesis of complex molecules from simpler ones, requiring energy input. On the other hand, catabolic pathways involve the breakdown of complex molecules into simpler ones, releasing energy. Different enzymes are needed because these pathways have distinct functions and chemical reactions.
In conclusion, the opposing nature and specificities of anabolic and catabolic pathways require distinct enzymes for proper function and regulation.

Answers
The percentage of the population that is a carrier of sickle cell disease is 91%. This is calculated by subtracting the 9% of the population that exhibit signs and symptoms of the disease from the total population (100%).
What is disease?Disease is an abnormal condition that affects the body of an organism and can cause discomfort, dysfunction or even death. It is often caused by pathogens such as viruses, bacteria, fungi, parasites, or environmental factors such as radiation or chemicals. It can be caused by genetic predisposition or lifestyle choices, such as smoking or poor diet. Symptoms of a disease depend on the type and can range from mild to severe.
This leaves 91% of the population that is a carrier of the disease but does not show any symptoms. This is due to the fact that a person who is heterozygous for the sickle cell allele (has one sickle cell allele and one normal allele) typically does not show any symptoms of the disease.

4. In horses, black color (B) is dominant over chestnut color (b). In a Punnett
square, show the cross between two hybrid black horses.
B
Answers
Answer:
The cross between two hybrid black horses would produce three black and one chestnut horse, shown in a Punnett square as required.
Explanation:
According to the question, the coat color in horses follows Mendelian inheritance, where the gene for black coat color (denoted by B) is dominant over the gene for chestnut coat color (denoted by b). Thus, for a horse to have a black coat color, either of the two genotypes may be possible : (i) BB and (ii) Bb.Bb is termed heterozygous or may be referred to as hybrid black. However, to have a chestnut coat color, the horse must have the genotype bb.How to make a Punnett square to determine the cross between two hybrid black horses?
To make the Punnett square, we must know the gametes produced by the two parent individuals. Here, both parents are hybrid black (Bb). So each of the two parents will produce two types of gametes --- one bearing the gene for black coat color (B) and the other bearing the gene for chestnut coat color (b).These gametes are then placed in a Punnett square and all possible gamete combinations are obtained. Here, since two gametes from each parent are involved, so the number of possible combinations = 2² = 4. These combinations are : BB ---- True black/ homozygous black Bb ---- Hybrid black/ Heterozygous blackBb --- Hybrid black/ Heterozygous blackbb ---- chestnut Therefore, phenotypic ratio = Black : Chestnut = 3 : 1And genotypic ratio = BB : Bb : bb = 1 : 2 : 1.

Answers
The correct option is A: a wind turbine generating electric current as it spins, is similar to a green leaf during the daytime.
Explain the working of wind turbine?The basic idea behind how a wind turbine operates is that, unlike a fan, which creates wind by using energy, a wind turbine creates electricity by utilising wind.
A turbine's blades, which resemble propellers, rotate around a rotor, spinning a generator to produce power.
Solar energy takes the form of wind when three things happen at once:
Uneven climate warmth caused by the sunIrregularities of a earth's surfacethe earth's rotation.Process:
The rotor blades of a wind turbine, which function similarly to an aeroplane wing or a helicopter rotor blade, convert wind energy into electrical energy using aerodynamic force. The air pressure with one blade's other side falls as wind passes across it.The rotor spins because the force of a lift is greater than the force of the drag. If the generator is a direct drive turbine, the rotor is connected to it directly; otherwise, a gearbox that speeds up the rotation and permits a smaller generator is used. Electricity is produced as a result of the conversion of aerodynamic force into generator rotation.To know more about the wind turbine, here
