If soil have all nutrients, then why do we need to replenish it.
Urgent!!!
Answers
Answer:
because when we griw theplants over there all the nutrition will be already consumed so, we need to replenish it time to time.
(1) Nutrient uptake by plants
Plants take up several mineral ions such as nitrates(for general growth), phosphates (for root growth), magnesium (for chlorophyll).
In order for the plant to keep growing healthily, the soil has to be constantly replenished to supply them with the mineral ions required.
(2) Soil erosion/Percolation
Heavy precipitation, can result in the washing away of nutrients via percolation.

you are on a committee that is planning whether or not to build a dam on a nearby river to produce hydroelectric power. describe some of the advantages and disadvantages you should consider before deciding to build the dam.
Answers
Dams preserve water, generate power, cause mass migration, and are expensive. Dams regulate water supply for domestic, industrial, and electric uses.
What are the advantages and disadvantages of dams?A dam is a structure that stops or slows the flow of water on the surface or in the ground.
Advantages of building a dam are:
Water flow is controlled and used to meet household, agricultural, and industrial demands.The reservoir that was formed behind the dam can be utilized for a variety of purposes, including irrigation, water sports, and even other forms of recreational pursuits.The production of energy by dams does not result in any pollution because there is no release of greenhouse gases during this process.Dams are utilized in conjunction with the hydroelectric plant in order to produce electricity.Disadvantages are:
The construction of dams takes many years, which results in a decrease in the quality of life for individuals who live in areas that are now undergoing construction.The process of constructing dams is one that is both time-consuming and incredibly expensive.The building of massive dams causes significant damage to the surface of the earth, which in turn has negative effects on geological processes.People are leaving in large numbers because they don't want to live in the area where the dam is going to be built.Learn more about dams, here:

Explanation:
Generally speaking, connective tissue is a connecting tissue. its function depends a lot on the cells that make it up, but in general, we can say that this type of tissue is responsible for promoting the support of other tissues in the body. This is because the connective tissue is able to fill empty spaces between the fabrics, in addition to being able to provide necessary nutrition to these fabrics whenever necessary.

A rock has been sent on a journey down through the layers of the Earth until it reaches the inner core. Explain what happens to the atoms in the rock as it moves through each layer.
Answers
Answer:
The rock components of the crust are slowly but constantly being changed from one form to another and the processes involved are summarized in the rock cycle (Figure 3.2). The rock cycle is driven by two forces: (1) Earth’s internal heat engine, which moves material around in the core and the mantle and leads to slow but significant changes within the crust, and (2) the hydrological cycle, which is the movement of water, ice, and air at the surface, and is powered by the sun.The rock cycle is still active on Earth because our core is hot enough to keep the mantle moving, our atmosphere is relatively thick, and we have liquid water. On some other planets or their satellites, such as the Moon, the rock cycle is virtually dead because the core is no longer hot enough to drive mantle convection and there is no atmosphere or liquid water.

If you wanted to design an artificial chromosome that would be mitotically stable in a yeast cell, what would be the essential DNA elements that you would need to include?:
Select one or more:
a. a yeast centromere.
b. a yeast origin of replication.
c. telomere sequences.
d. Genes that code for histones
e. None of the above are necessary
Answers
If you wanted to design an artificial chromosome that would be mitotically stable in a yeast cell, options a, b, and c are necessary to include.
To design an artificial chromosome that would be mitotically stable in a yeast cell, the essential DNA elements that need to be included are:
a. a yeast centromere - The centromere is a specialized DNA sequence that is necessary for the proper segregation of chromosomes during cell division. In yeast, the centromere is essential for the formation of a functional kinetochore, which is necessary for the attachment of the chromosome to the spindle fibers during cell division. Therefore, the inclusion of a yeast centromere is necessary for the artificial chromosome to be mitotically stable.
b. a yeast origin of replication - The origin of replication is a DNA sequence that is necessary for the initiation of DNA replication. In yeast, the origin of replication is required for the replication of the chromosome during cell division. Therefore, inclusion of a yeast origin of replication is necessary for the artificial chromosome to be mitotically stable.
c. telomere sequences - Telomeres are specialized DNA sequences that are located at the ends of chromosomes and are necessary for the protection of the chromosome ends from degradation and fusion. In yeast, telomere sequences are required for the maintenance of chromosome stability during cell division. Therefore, inclusion of telomere sequences is necessary for the artificial chromosome to be mitotically stable.

What is the inherited variation?
please hurry
Answers
Answer:
Genetic variation is the difference in DNA among individuals or the differences between populations. There are multiple sources of genetic variation, including mutation and genetic recombination.
Explanation:
The size of the lizards' legs is the inherited variation in this situation. It is likely that hereditary variables, which can be transferred from parents to children, are responsible for the variance in leg size.
What is an inherited variation?Genetic changes that are transferred from parents to children are referred to as inherited variation. Every person has a distinct set of genes that influence a variety of qualities, including physical attributes, behaviour, and disease risk. These genes, which a person inherits from both parents, are prone to chance mutations that happen throughout DNA replication and recombination.
In the aforementioned illustration, this genetic variation in leg length resulted in differential availability of food, with longer-legged lizards having better access to food sources. Because they had a harder time getting to food and might have been less fit, lizards with shorter limbs gradually decreased in population.
Therefore, the size of the lizards' legs is the inherited variation in this situation. It is likely that hereditary variables, which can be transferred from parents to children, are responsible for the variance in leg size.

What is the most likely cause of this? OA. Hybridization via backcrossing OB. Hybrid speciation O C. Horizontal gene transfer via bacteria O D. Introgression via backcrossing
Answers
The biological species theory is not applicable to asexual organisms. So, option A is correct. Introgression via backcrossing theory is used to find DNA makes up 1-4% of the human genome. Thus, option D is correct.
Ernst Mayr stated a theory called the biological species concept which states that a group of organisms can interbreed and can able to fertile their offspring, but this concept is very less applicable when dealing with asexual organisms.
Introgression is a process related to genetic material which transfers between two species through repeated backcrossing. It is believed that over a long period of time, humans interbred with Neanderthals so that the genetic material is incorporated between these species.
