The incidence of cystic fibrosis, a recessive genetic disorder in the Caucasian population of United States, is 1 in every 2,500 individuals. Find the number of heterozygous carriers. (p + q = 1, p2 + 2pq + q2 = 1)

Answers

Answer 1

Answer:

The no. of heterozygous carriers = 0.0392

Explanation:

From the given information:

The incidence of this recessive disorder i.e. q² = 1/2500

q² = 0.0004

q = 0.02

From Hardy Weinberg's Equilibrium.

p + q = 1; &

p² + 2pq + q² = 1

p + 0.02 = 1

p = 1 - 0.02

p = 0.98

So, the numbers of heterozygous carrier 2pq is:

= 2 × 0.98 × 0.02

= 0.0392

Which is held constant when a gas obeys Boyle's law?

A. motion
B. pressure
C. temperature
D. volume

Answers

Answer:

B

Explanation:

ganyan rin sagot ko sa module ko

When a gas obeys Boyle's law, the temperature is held constant. The correct option is C.

What is Boyle's law?

Boyle's law is given by Charles Boyle. It is a gas law that states the pressure decrease with the increase in the volume and the temperature remain constant. In other words, the pressure exerted on gas is inversely proportional to the volume of the gas.

The law shows the relationship between pressure and volume, with the temperature remaining constant. There are three gas laws which are given by different scientists. These laws show the relationship between two variables and the third remains constant. These variables are temperature, volume, and pressure.

Thus, the correct option is C. temperature regarding the gas obeys Boyle's law, and it remains constant.

although farmers once used only organic fertilizers to replenish nutrients in the soils, some have been replaced with synthetic fertilizers. Although synthetic fertilizers keep nutrient levels high and increase crop yields, they can have an effect on the environment. Which of the following would most likely lead to a ban of synthetic fertilizers?


A. Synthetic fertilizers help prevent the spread of diseases.


B. Synthetic fertilizers are less expensive than organic fertilizers.


C. Synthetic fertilizers increase the potential for environmental pollution.


D. Synthetic fertilizers provide nutrients, like nitrogen that can disrupt nutrient cycling.

Answers

Answer: C. Synthetic fertilizers increase the potential for environmental pollution.

Explanation:

A fertilizer is a material which when applied to soil ,supply one or more plant nutrients essential to the growth of plants.

Fertilizers could be organic ( obtained from nature ) or could be synthetic ( made artificially in labs).

Though synthetic fertilizers such as urea keep nutrient levels high and increase crop yields but they also kill beneficial microorganisms in the soil that convert dead human and plant remains into nutrient-rich organic matter. The non biodegardable synthetic fertilizers seep into groundwater and increase its toxicity, causing water pollution.

Synthetic fertilizers damage the natural makeup of the soil. Plants that grow in soils which use synthetic fertilizers are deficient in iron, zinc, carotene, vitamin C, copper and protein.

Give three differences between parenchyma and selerenchyma? ​

Answers

Answer:

Parenchyma cells have thin primary walls and usually remain alive after they become mature while Sclerenchyma cells have thick lignified secondary walls and often die when mature.

Parenchyma forms the "filler" tissue in the soft parts of plants while  Sclerenchyma provides the main structural support to a plant.

Parenchyma cells are usually loosely packed with large intercellular space while Sclerenchyma cells has no intercellular spaces between the cells.

Context: The quotation marks outside the words are the basis for comparison

Parenchyma: (1) “Found in” These type of cells are present in every soft part of the plant. (2) “Type of cell” Unspecialized and living cells. (3) “Cell shape” There are various shapes of the cells, but generally, they are isodiametric.

Sclerenchyma: (1) “Found in” it is found in mature parts of the plants or trees. (2) “Type of cell” specialized, matured and dead cells. (3) “Cell shape” Sclereids, elongated and fibre shape.

Identify the natural processes that occur on the earth's surface to make and destroy rocks.

Answers

The physical processes on Earth create constant change. These processes—including movement in the tectonic plates in the crust, wind and water erosion, and deposition—shape features on Earth's surface.

Answer:

You learned about the three rock types: igneous, sedimentary, and metamorphic. You also learned that all of these rocks can change. In fact, any rock can change to become any other type of rock. These changes usually happen very slowly. Some changes happen below Earth’s surface. Some changes happen above ground. These changes are all part of the rock cycle. The rock cycle describes each of the main types of rocks, how they form, and how they change.

The figure below shows how the three main rock types are related to each other (Figure below). The arrows within the circle show how one type of rock may change to rock of another type. These are the processes that change one rock type to another rock type.

How is an ectotherm most likely to maintain homeostasis during cold weather?
A. By sitting on a warm surface
B. By lying in the shade
C. By shivering
D. By sweating​

Answers

The answer is A! Sitting on a warm surface

Ectotherm describes the animals that use external sources to maintain their body temperature. They will maintain their homeostasis in cold weather by sitting on a warm surface. Thus, option A is correct.

What are ectotherms?

Ectotherms are animals that cannot regulate their body temperature on their own and are dependent on external sources to maintain their body heat.

They have to depend on environmental sources like a warm place to maintain their body temperature during the cold weather. They cannot sweat or shiver to maintain homeostasis.

Therefore, during the cold, ectothermic animals sits on warm surfaces to maintain homeostasis.
