Renewable resources are those resources which are inexhaustible in nature . It means these resourses are present in unlimited quantity and are environment friendly.

Geothermal energy is one of the example of renewable resources.

In geothermal energy, The word ' geo' stands for earth. So ,It basically means the energy that is extracted from the earth.

Here are some uses for the utilisation of renewable geothermal energy.

The geothermal power plant extract the heat from geothermal reservoirs. Then, This extracted heat is transfer to the heat engine .Which are responsible for running the heat engine smoothly and generation of electricity.

The heat that is released from the underground reservoirs are used to reduce green house gases because Geothermal energy needs very less CO2 . This heat is transfer in green house and it results into direct heating of green houses.

There are so many people who wish to enjoy their leisure time peacefully. In winters, People like to visit the areas where hot spots are found .Which is a example of geothermal energy.

The warm water is taken from underground reservoirs and then converted into hear energy. Then this heat energy is transfer in the building by using geothemal pumps helps in generating heat in building in winter. This same process is also follows for cooling of building.

Geothermal energy is also used in industries for cooking, pastuerizing milk etc.

Explanation:

D) and E), anaphase II of meiosis and anaphase I of meiosis has  basis for the Mendel's observation of the segregation of alleles in gamete formation.

Anaphases I and II of meiosis which is where Mendel's Segregation law actually occurs. The homologous chromosomes are divided up into two daughter nuclei with their multiple versions of each gene during this stage of the first meiotic division.

According to the law of segregation, two alleles of a single trait will randomly separate, with a 50% chance that either allele will probably wind up in either gamete. This is connected to one gene. In accordance with the law of independent assortment, an allele from one gene separates from an allele from another gene on its own.

Based on the given information, the scientist can conclude that a physical change has occurred rather than a chemical reaction.

The scientist can make this conclusion because the samples did not show any signs of bubbling or dissolving in water, which are common indications of a chemical reaction.

Additionally, the measurement of the mass and volume of the samples shows that there has been a change in both properties. Sample two has a greater volume and mass compared to sample one, indicating that some physical transformation has taken place.

However, without further information or analysis, it is not possible to determine the exact nature of the physical change or identify the substances involved.

Answer:

Explanation:

La cellule humaine comprend 46 chromosomes, porteurs du code génétique de l'espèce humaine. Le nombre de chromosomes est de 46 chez l'homme : 22 paires d'autosomes et 2 chromosomes sexuels ou gonosomes, XX chez la femme et XY chez l'homme.

Chromosomes present in the human body are in a pair of 23. These 23 pairs of chromosomes are also divided into two sub-division called autosome and sex chromosome. The autosome is 22 in pair and the sex chromosome are 1 in pair.

Autosomes help in inheriting the characteristics from parent to offspring, whereas sex chromosome help in determining the sex of the offspring. Therefore, the human haploid number is n = 23, haploid number refers to the  number of chromosomes present in a single set that is denoted by n. Each of these chromosome pairs exists with diploid cells.

Hence, humans are diploid containing 46 chromosomes that divide to half forming 23 pair of chromosomes.

Answer:

your grass would get brown and die

Explanation:

Salt is commonly found in small quantities in soil. But in large quantities, it stops plants from absorbing necessary nutrients such as phosphorous and potassium, and it absorbs water the plants need to survive. This can dehydrate the roots of the grass in your lawn and cause it to turn brown and die.

Answer:

Our environment supports and houses our ecosystems, allowing them to grow and thrive. If we fail to protect our environment, we will put the lives of humans, animals, plants and more at risk.

Why is it important to preserve natural resources for future generations?

Conservation is the practice of caring for these resources so all living things can benefit from them now and in the future. All the things we need to survive, such as food, water, air, and shelter, come from natural resources. Some of these resources, like small plants, can be replaced quickly after they are used.

How do environmental problems affect the life of the future generation?

Children's immune systems are still developing, leaving their rapidly growing bodies more sensitive to disease and pollution. Extreme events can destroy homes, schools, childcare centers and infrastructure critical to children's well-being. Droughts and flooding can destroy crops and cut access to clean water.

Answer:

Quadrat method is used for estimating the number of individuals in an area. In this method, a large square area on the ground or water surface is marked, call it an enclave. The number of animals present in this enclave is counted. Then by assuming that the animals are less migratory and are uniformly distributed, their number for a large area is estimated by the use of unitary method of calculation. Example a 4 square feet area has 2 snails, then a 1000 square feet area will have (1000 x 2)/4, i.e, 500 snails in it. Fishes can be counted using this method only if they are confined in a small water body like a lake or a pond. Rivers are flowing so the fishes may move along its length which can give us an underestimate or an overestimate of their numbers. Sea has its depth and huge area, and fishes can be moving randomly in it. Hence this method will not work for river and sea fishes.

photosynthesis by ocean plants

Explanation:

The acceleration of the car is 2 m/s².

The average velocity of the car is 2 m/s.

The equation acceleration = (final velocity - beginning velocity) / time can be used.

Given:

Initial velocity (u) = 0 m/s (since the car starts from rest)

Final velocity (v) = 20 m/s

Time (t) = 10 s

Using the formula, we can substitute the values:

acceleration = (20 m/s - 0 m/s) / 10 s

acceleration = 20 m/s / 10 s

acceleration = 2 m/s²

Therefore, the acceleration of the car is 2 m/s².

You can use the following equation to determine the average velocity: average velocity = total displacement / total time.

The initial position and the final position are identical since the automobile begins at rest. As a result, the displacement and the ultimate position are equal.

Given:

Displacement = 20 m

Time (t) = 10 s

Using the formula, we can substitute the values:

average velocity = 20 m / 10 s

average velocity = 2 m/s

Therefore, the average velocity of the car is 2 m/s.

Answer:

17 number on the diagram is pointing to the deltoid muscle

The answer is Option a, concentration of dissolved salt in the solution is greater than the concentration in the cells. Here the statement describes the characteristics of a hyper-tonic solution.

In comparison to another solution, a hyper-tonic solution has a higher solute concentration. The hypo-tonic solution is the opposite solution with a lower concentration. Scientists must compare the contents of cells to their surroundings. A cell is said to be hypo-tonic if it is placed in a hyper-tonic solution.

The environment is hypo-tonic, or more weakly concentrated, if the cell's cytoplasm is a hyper-tonic solution. Due to the fact that solutes and water have a tendency to diffuse or flow along gradients, this is extremely important. One solution will eventually result from the combination of two solutions.

The solutions will become isotonic when the water passes between the two solutions if the solutions are separated by a permeable barrier that only enables water to pass through. Despite having varying volumes, isotonic liquids have the same concentration.

The electrical activity of these cells relies on the positive and negative charges of the ions in the hyper-tonic solution.

Hyper-tonic Solution Examples

1. Human Kidney

The human brain contains unique proteins called osmoreceptors that are able to gauge the osmolarity of the environment surrounding the cell in order to control the amount of water in the body. Because there isn't enough water in the blood to hydrate the solutes, the environment can become a very hypertonic solution.

2. Sea Turtle Osmoregulation

Salt water is a solution that is more hyper-tonic than fresh water. This suggests that a cytosol that is more hyper-tonic than salt water is required for cells to operate. In contrast to freshwater turtles, sea turtles, for instance, live in a considerably more hypertonic environment.

Precipitation and percolation are the hydrologic cycle stages that are essential for recharging an aquifer that has had groundwater withdrawn. The water that seeps through the earth and refills the aquifer is provided by precipitation.

A portion of the water from precipitation that falls on land flows off into lakes and rivers. Rainfall and snowmelt both produce some water that seeps into the soil and descends into the saturated zone. This process is known as recharging, and the regions where it takes place are known as recharge zones.

Rain, precipitation, and the flow from rivers, streams, and creeks seep into an aquifer naturally as part of the hydrologic cycle. Farmers irrigate fields and orchards, which allows water to seep into the ground.

Answer:

Organic fertilizers continue to improve the soil long after the plants have taken the nutrients they need. Therefore, the longer your soil is fed with organic fertilizers, the better its composition and texture. So, while inorganic fertilizer is cheaper in the short term, it adds less to the soil in the long term.

The stages of bee development are egg, larva, pupa, and adult. Eggs hatch into larvae, which then transform into pupae. Finally, adult bees emerge and undergo further maturation.

The stages of bee development are:

1. Egg: The bee life cycle begins when the queen bee lays an egg in a honeycomb cell.

2. Larva: The egg hatches into a larva, which is a legless, grub-like creature. The larva is fed a special diet called royal jelly, which stimulates its growth.

3. Pupa: The larva undergoes metamorphosis and transforms into a pupa. Inside the sealed cell, the pupa undergoes various changes, developing into an adult bee.

4. Adult Bee: After completing the pupal stage, the fully developed adult bee emerges from the cell. The bee then undergoes further maturation, such as its exoskeleton hardening, wings expanding, and adult coloration appearing.

It's important to note that there are three castes of bees: queen, worker, and drone. The development process for each caste is similar, but the diet and size of the cells they are raised in differ, leading to their distinct roles within the colony.

b) They are produced only by organs called endocrine organs.

Explanation:

Hypothalamus can be defined as a small portion of the mammalian brain responsible for the secretion of hormones through the stimulation of the pituitary gland.

It is located between the midbrain and the thalamus. Also, hypothalamus is the most inferior portion in the diencephalon of the forebrain.

Basically, hypothalamus is the most important portion of the brain in vertebrates that controls various bodily functions.

An endocrine system refers to a series of ductless glands and organs responsible for the production and secretion of hormones that are used by the body for the performance of various functions such as metabolism, controlling growth, reproduction, mood, sleep, etc. These hormones are secreted directly into the circulatory system (blood) and then transported to the organs and tissues in the body.

The following statements about hormones are correct;

I. Glands saddled with the responsibility of producing hormones are ductless glands i.e directly secreting hormones into the bloodstream.

II. Hormones are either soluble in water or insoluble in water.

III. Hormones are often responsible for maintaining steady-state conditions in the body of a living organism through homeostasis.

IV. Hormones are typically able to turn genes off or on.
