Answer:
One of the characteristic feature of the phospholipid bi- layer is that like dissolve likes.Therefore,polar molecules and compounds pass though the hydrophllic heads,while non-polar lipid soluble substances pass through the hydrophobic tail,but can not diffuse across the head.
The plasma membrane is amphipathic.It is made up of the hydrophilic heads and hydrophobic tails
Cortisol is made of lipid.Therefore,it will diffuse easily across the bi layer of the plasma membrane though the tail,while LH and Epinephrine,will not diffuse across this hydrophobic barriers,since they are made up of polar molecules.

How would an air mass that formed over the north pole differ from an air mass that formed over a warm
ocean?
Answers
An air mass that formed over the North Pole would differ from an air mass that formed over a warm ocean in several ways.
Air masses are large bodies of air with similar characteristics that form over a specific region of the Earth's surface and can travel long distances before encountering a different air mass that alters its characteristics. The characteristics of an air mass depend on the region over which it forms.
The air mass that forms over the North Pole would be cold and dry due to the absence of sunlight and the Arctic's high latitudes. Arctic air masses are characterized by a high pressure system that circulates air clockwise. This rotation traps cold air over the region and prevents it from mixing with the surrounding air masses.
The air mass that forms over a warm ocean would be warm and moist. The ocean surface warms the air above it, and the air acquires moisture through evaporation. The warm air then rises, causing low-pressure areas over the ocean and pulling in moisture-laden air from surrounding regions. This moist air mass travels over land, and its temperature decreases, causing it to lose its moisture content and form precipitation.
The moisture content in this air mass would be high, causing it to be humid. Air masses interact with each other and cause changes in weather patterns and climate. They also play a vital role in the Earth's energy balance and regulate temperature and precipitation patterns.

37. What is the distance from Passas Street at the
margin of the map to where it meets Route 84?
Answers
Answer:
3 1/2
Explanation:
The distance from Passes Street at the margin of the map to where it meets Route 84 is 3 1/2 miles.
What are measurements?The comparison of an unknown amount with a known quantity is referred to as measurement. The measurement yields a numerical value with specific units. Any given object's length, mass, capacity (volume), and temperature can be measured.
Distance is defined as an object's entire movement without regard for direction. The distance can be defined as how much ground an object has covered, regardless of its starting or ending place.
Mile, any of several distance units, such as the statute mile of 5,280 feet (1.609 km). It was derived from the Roman mille passus, or "thousand paces," which was equivalent to 5,000 Roman feet.
Therefore, the distance from Passes Street at the map's edge to where it intersects Route 84 is 3 1/2 miles.

If the concentration of A is doubled and the concentration of B is halved, the rate of the reaction would _____ by a factor of _____. Select one: a. increase, 4 b. increase, 2 c. decrease, 2 d. decrease, 4
Answers
The rate of reaction, in this case, would be reduced to half. So the correct option is C.
What is the order of a reaction?The relationship between the rate of a chemical reaction and the concentration of the reactive species that are taking part in the reaction is called the order of the reaction.
When the rate of reaction depends on the concentration of only one of the reactants, it is called a first-order reaction. When the rate of these reactions depends upon the square of the concentration of one reactant or the concentration of two reactants, it is called a second-order reaction.
Hence, when the reaction is first order compared to A and second order compared to B, the rate equation will be
[A] [B]²
When the concentration of A is doubled and the concentration of B is halved
2 × (1/2)² = 2 × 1/4 = 1/2.
Therefore, the rate of reaction will be halved.

Which property of a plant species would be MOST USEFUL for meeting the scientists' goal?
Answers
The property of a plant species that would be MOST USEFUL for the scientists' goal of developing a useful crop plant through selective breeding is Very high genetic variation. The correct answer is option B.
High genetic variation within a plant species means that there is a wide range of genetic traits and characteristics present. This provides a greater chance of finding desirable traits that can be selected for and developed in the breeding process. By selecting plants with specific desired traits and crossing them, scientists can increase the likelihood of producing offspring with those traits. Over time, this can lead to the development of a new plant variety with improved qualities such as higher yield, resistance to pests or diseases, or improved nutritional value. Therefore, the correct answer is option B.In summary, a plant species with very high genetic variation would be most useful for the scientists' goal of developing new farm crops through selective breeding because it increases the chances of finding desirable traits and allows for the development of improved qualities in the offspring.For more questions on selective breeding

The frequency of allele A2 is 0.3 or 30%. Does this mean that 30% of the individuals in the population will have an A2 phenotype?
Answers
Answer:
No, the frequency of an allele (in this case, A2) refers to the proportion of all alleles in the population that are A2. This does not necessarily mean that 30% of the individuals in the population will have an A2 phenotype, as the phenotype of an individual is determined by their specific combination of alleles.

In a population the homozygous dominant individual make up 70% of the population while heterozygous ones made up 21% and recessive made up 9%. What are the frequencies of the A and a alleles?
Answers
There are two alleles in a population that influence a specific attribute. Using the letters "A" for the dominant allele and "a" for the recessive allele. A allele frequency is 0.7, whereas frequency of allele is 0.09.
The frequency of the A allele is 0.7, or 70%, since homozygous dominant (AA) genotypes account for 70% of the population. Similarly, since homozygous recessive (aa) alleles make up 9% of the population, we can infer that the frequency of the recessive allele, a, is 0.09, or 9%.
The formula 2pq = frequency of heterozygotes, where p is the frequency of the A allele and q is the frequency of the an allele, can be used to determine the frequency of the heterozygous genotype (Aa).
We know that the frequency of heterozygotes is 0.21, or 21%.
Plugging in the known values:
2 * 0.7 * q = 0.21
Solving for q:
q = 0.15
So, the frequency of the A allele is 0.7, and the frequency of the a allele is 0.09.

Answers
Answer:
The change in red blood cell movement is principally due to the movement of salt
The change in red blood cell volume is principally due to the movement of water.
What happens to red blood cells in water?The red blood cells can swell or shrink depending on the concentration of solutes (salt and other dissolved particles) and the concentration of water in the surrounding solution. When the concentration of solutes is higher inside the cell than outside, water will move out of the cell, causing it to shrink.
When the concentration of solutes is lower inside the cell than outside, water will move into the cell, causing it to swell. In the chart provided, the change in red blood cell volume is likely due to the movement of water in response to the different concentrations of solutes in the suspensions.

Forested floodplain wetlands benefit from periodic flooding from rivers. When floodwaters spill into the wetland, they bring water and nutrients and leave both behind. But humans have often cut off floodplains from rivers by building roads, levees, berms, etc. Think about what would happen if a river could no longer flood into these areas. How would the resulting increased amount of water and nutrients in the river affect soils, hydrology, and life downstream?
Answers
The absence of flooding from rivers into forested floodplain wetlands would lead to adverse effects on soils, hydrology, and the overall biodiversity downstream, emphasizing the importance of maintaining the natural connection between rivers and floodplains for the health and functioning of these ecosystems.
If a river can no longer flood into forested floodplain wetlands due to human interventions, it would have significant consequences for the downstream areas in terms of soils, hydrology, and life.Without periodic flooding, the increased amount of water and nutrients in the river would not be able to disperse and be deposited in the floodplain wetlands. As a result, downstream soils would experience a decrease in nutrient inputs, leading to decreased fertility and altered composition. The absence of regular flooding would disrupt the natural hydrological cycle, reducing the recharge of groundwater and altering the flow patterns in the river system. This could result in decreased water availability, increased erosion, and changes in the overall ecosystem dynamics downstream.The disruption of nutrient flows and hydrological patterns would also have a significant impact on the life forms downstream. Aquatic plants, fish, and other organisms that depend on floodplain wetlands for breeding, feeding, and shelter would face habitat loss and reduced food availability. This, in turn, could disrupt the food chain and impact the abundance and diversity of aquatic and terrestrial species in the downstream areas.The absence of flooding from rivers into forested floodplain wetlands would lead to adverse effects on soils, hydrology, and the overall biodiversity downstream, emphasizing the importance of maintaining the natural connection between rivers and floodplains for the health and functioning of these ecosystems.For more such questions on flooding

In which mitotic phase does the process of cytokinesis conclude? (1 point)
O interphase.

O prophase.
O metaphase.
Answers
When cytokinesis reaches telophase, it has completed the mitotic phase.
Explain about the telophase?Each set of chromosomes produces a nuclear membrane that separates the nuclear DNA from the cytoplasm during telophase. The chromosomes become less tightly wound and more dispersed as a result of uncoiling.
After telophase, there is a process known as cytokinesis in which the cytoplasm is divided into two daughter cells. The outcome of this technique is the generation of genetically identical daughter cells. In mitosis, an even division of each duplicate chromosome occurs. Two identical nuclei are consequently formed during telophase. Because they will behave in the same way, these cells can be used to regenerate damaged cells or to produce complete beings from a single zygote.
