Dams are man-made constructions placed on water bodies like rivers and streams to control the water flow there.

Diversion dam: These are dams designed to change the direction of the flow of water in a body of water.

Cofferdam: These are temporary dams built to contain water while construction is taking place close to a water body.

Storage dams are dams designed to hold water in a body of water when it rains. In order to generate energy or for agricultural use, this water is stored.

Detention dam: These are dams designed to regulate the amount of water in a body of water during a flood.

How are the four different types of dams compared?

Diversion dams are smaller in height than other types of dams.

Diversion dams are less capable of storing water than other types of dams.

In contrast to other dams, cofferdams are constructed for short-term use.

Answer: Carbon Dioxide

Explanation:

Carbon dioxide is the greenhouse gas which is released from burning fossil fuels.

Greenhouse gases are gases capable of absorbing infrared light and trapping heat in our atmosphere. Greenhouse gases cause the greenhouse effect or global warming.

The greenhouse gases are so named because their action is comparable to how glass walls trap heat inside a greenhouse. Carbon dioxide is the principal greenhouse gas generated by the combustion of fossil fuels, but tiny quantities of nitrous oxide and methane are also emitted.

Fossil fuels consist of coal, oil, and gas. Hydrocarbon molecules serve as the foundation for these fuels. As a result, when these fuels are burned, carbon dioxide is released. Some fossil fuels contain components that emit nitrous oxide or methane.

The chance that the rabbits will show the black trait is likely to be low, as the recessive pigment gene is only active at temperatures below 25° Celsius.

The temperature affects the expression of the recessive pigment gene in Himalayan rabbits by determining whether or not the gene is active. At temperatures below 25 ° Celsius, the gene is active and codes for the production of an enzyme that darkens the fur on the nose, ears, and feet, resulting in the black coloration. At higher temperatures, the gene is not active and the enzyme is not produced, leading to the expression of the normal coloration. So the black trait is only present when the temperature is below 25 °C and is not expressed at higher temperatures.

Covering fossils in plaster is a common technique used to protect and preserve them. The main reason for covering fossils in plaster is to stabilize and protect the fossil from further deterioration. Fossils are often found in fragile and delicate states, and plaster provides a protective layer that helps to prevent further erosion or damage caused by exposure to the elements or handling. Plaster also provides a hard, durable surface that makes it easier to transport and handle the fossils without causing additional damage.

Additionally, the plaster can be used to make a mold of the fossil. This allows for a replica to be made which can be used for research, study or display, without risking damage to the original fossil.

Finally, plaster is also useful for reconstructing missing or broken parts of the fossil, which can make it easier to study and interpret the fossil.

In summary, covering fossils in plaster is necessary to protect and preserve them, to make a replica, and to reconstruct missing or broken parts.

A plant that grows toward light shows a mechanism known as Phototropism.

Phototropism may be defined as the tropic movement of plants in response to light. In this case, light functions as a stimulus, and the plant expresses growth movement in the direction of the stimulus, that is light.  Phototropism is exhibited due to auxin which is a plant growth hormone.

Basically, the shoot of plants exhibits positive phototropism as it grows in the direction of light.  It is one of the many plant tropisms or movements which respond to external stimuli. Growth towards a light source is called positive phototropism, while growth away from light is called negative phototropism.

Explanation:

If the 23rd pair of chromosomes read XY in humans then is read as a B. male because in humans we have two sex chromosomes.

The sex chromosomes X and Y in the human species are two different chromosomes when compared to the autosomal somatic chromosomes which specify the sex of an individual, If an individual inherits two X chromosomes then it is female, but if an individual inherits one Y chromosome and a Y chromosome then it is male.

Therefore, with this data, we can see that the sex chromosomes X and Y in the human species are those chromosomes that specify the sex in humans and the presence of one Y chromosome leads to the generation of an individual with male sex features instead of autosomal chromosomes.

This method of cloning works because egg cells are pluripotent and therefore reprogrammable.

What do you mean by cloning?

Cloning is the process of creating genetically identical copies of an organism. This can be done through asexual reproduction, or it can be done artificially through methods such as genetic engineering. Cloning is a powerful tool used in biotechnology, and it has numerous applications in medicine, agriculture, and other areas. Cloning can be used to create genetically identical animals, plants, and even humans.

Pluripotent cells are stem cells that are capable of becoming any other type of cell in the body. This means that they have the ability to be reprogrammed into any other cell type, including those that make up an egg cell. This ability to be reprogrammed makes them ideal for cloning, as scientists can take a pluripotent cell and use it to create an egg cell that is genetically identical to the original cell. Once the egg cell is created, it can be used to create a clone of the original cell.
