What is genetic variation in plants??
Answer:
Individual differences or population differences are referred to as genetic variations.
Explanation:
Individual differences or population differences are referred to as genetic variations. Plant breeders can use genetic variability/diversity to improve cultivars with desired qualities and generate new cultivars with both farmers- and breeder-preferred traits (yield potential, early maturity, good shapes, taste, color, extended shelf life, easy to prepare) (disease and pest resistance). Plant breeders and local farmers have harnessed natural genetic variability to boost their yield. GA plays a crucial part in the alleviation of poverty as the population grows. Plant breeders benefit from population variation because it allows them to explore the source and develop new cultivars. Mutation, hybridization between incompatible kinds or introgression, wide-hybridization, and recombination could all be used to accomplish this. Mutation, natural selection, environmental diversity, genetic drift, migration, and population size all have an impact on genetic variability.
Answer:
Gene variation in plants often occurs as the result of gene flow. Pollen is dispersed from one area to another by the wind or by pollinators over great distances. Examples of genetic variation in animals include albinism, cheetahs with stripes, snakes that fly, animals that play dead, and animals that mimic leaves.

Which of the following equations represents the right chemical process that occurs in photosynthesis? Question 8 options: A) Six molecules of carbon dioxide plus six molecules of water plus light energy converts six molecules of oxygen plus sugar. B) Six molecules of oxygen plus six molecules of water plus light energy converts six molecules of carbon dioxide plus sugar. C) Six molecules of water plus six molecules of hydrogen plus six molecules of oxygen converts light energy plus sugar. D) Six molecules of carbon dioxide plus sugar plus light energy converts six molecules of carbon and six molecules of oxygen.
Six molecules of carbon dioxide plus six molecules of water plus light energy converts to six molecules of oxygen plus sugar, Thus, the correct option is A.
What is photosynthesis?Photosynthesis is the process through which plants use sunlight to create their own nourishment. Through a sequence of reactions, light energy from the sun is turned into chemical energy, which is then stored in the form of food.
In the presence of sunlight, 6 molecules of carbon dioxide (CO2) and 6 molecules of water (H2O) react to form 1 molecule of glucose sugar. During photosynthesis, 6 molecules of oxygen are formed in addition to glucose.
The following is a balanced chemical reaction for photosynthesis:
Sunlight
6CO2 + 6H2O —---------> C6H12O6 + 6O2.
(carbon (water) (glucose) (oxygen)

What's function of ADH
ADH is the Antidiuretic hormone. This is a brain hormone that induces the kidneys to discharge less water, resulting in less generation of urine.
Arginine vasopressin is another name for ADH. The hypothalamus in the brain produces this hormone, which is then stored in the posterior pituitary gland.Vasopressin is a hormone that promotes vasoconstriction and water reabsorption in the renal tubules of the kidney.The amount of water in the blood is constantly regulated and balanced by ADH.Higher water concentration raises the volume and pressure of the blood. Water metabolism is maintained by osmotic sensors( to sense the osmotic pressure) and baroreceptors(to sense the blood pressure) in conjunction with ADH.ADH deficiency often results in an unusual water metabolism condition called diabetes insipidus. A reduction in either the generation of ADH by the hypothalamus or the release of ADH from the pituitary gland is the major causal factor of diabetes insipidus.Excessive urination( polyuria) is a common symptom of this disease, followed by intense thirst, known as polydipsia.To learn more about the ADH, refer to:-

Choose TWO locations below (A, B, C) and provide a two-sentence weather forecast for that location. Your forecast must include Wind direction, general wind speed (high, moderate, low) general temperatures (cold, cool, mild, warm, hot), and sky conditions(precipitation/stormy, sunny cloudy).
Climatic maps use isobars to read the barometric pressure and to determine climatic patterns in different areas. Points B and C are described below.
How to interpret a weather map?
Meteorology is determined mainly by barometric pressure, which is the pressure exerted by atmospheric air on the Earth's surface. It is measured in millibars, Mb.
Barometric pressure systems are closely associated with weather patterns, which is why it is used to create climatic maps.
⇒ Pressure:
An average pressure system at sea level ⇒ 1013 Mb.A high-pressure system ⇒ air descends ⇒ Good weather and few clouds ⇒ 1030 Mb.A low-pressure system ⇒ air ascends ⇒ Hot ascending air condense and forms clouds. Bad weather, storm probabilities ⇒ 1000 Mb.⇒ Isobars:
Used to read barometric pressures in climatic mapsThese are curve lines that indicate the areas with the same barometric pressures.They are arranged in concentric figures, one inside the other one. The smallest one indicates the pressure center.- High-pressure center is indicated with an H
- Low-pressure center is indicated with an L
Isobars are significant when determining wind speed and direction.
⇒ Wind direction:
In High-pressure center is indicated with clockwise arrows in the northern hemisphere
In Low-pressure center is indicated with counterclockwise arrows in the northern hemisphere
Winds tend to move from high pressure areas to low pressure areas.
⇒ Wind speed:
The closer isobars are between each other, the stronger and faster the wind is.
⇒ Front types:
Cold front ⇒ represented by blue lines with blue triangles pointing in the direction of the front movement. When a cold front passes by, there are high probabilities of strong winds and severe precipitations. Hot front ⇒ represented by red lines with red semi-circles pointing in the direction of the front movement. There is an increase in temperature as the front approximates. There might be precipitations. Occluded front ⇒ represented by purple lines with red semi-circles and blue triangles pointing in the direction of the front movement. It forms when a cold front overtakes a warm front. There might be storms.
Point C
Near a Low Pressure system Isobars: close to each otherMass of light, warm and wet air. Since the air is light, it tends to ascend, creating clouds and rains.Air pressure: low -around 1000 Mb-Weather conditions: cloudy, rainy, stormy.Wind direction: counterclockwise in the northern hemisphere.Wind speed: high to moderateTemperature: warm or hotA hot front is approximatingPoint B
Probably near a High Pressure system Isobars: separated from each otherMass of dense, cold/cool and dry air. Since the air is dense it tends to descend.Air pressure: high - around 1030 Mb-Weather conditions: clear, cloudlessWind direction: clockwise in the northern hemisphere.Wind speed: moderate to lowTemperature: cold or coolA cold front has passedYou can learn more about weather maps at

The cell membrane separates the intracellular space from the extracellular space. It controls what enters and leaves the cell. The correct answer is option B.
The term "plasma membrane" also refers to the cell membrane. It is the cell's outermost layer in animals. It is a membrane made of lipids and proteins that is semi-permeable. Between the outside environment and living systems, there is a plasma membrane. The plasma membrane regulates the movement of solutes and solvents between the cell and its surroundings. A plasma membrane's permeability properties include semi-permeability, impermeability, permeability, and selective permeability.
Therefore, the main function of the cell membrane is to control the entry and exit of materials in the cell. The correct answer is option B.
