Answer:
Usually three levels of biodiversity are discussed—genetic, species, and ecosystem diversity. Genetic diversity is all the different genes contained in all individual plants, animals, fungi, and microorganisms. It occurs within a species as well as between species. Ecological diversity
Ecological diversity is the largest scale of biodiversity, and within each ecosystem, there is a great deal of both species and genetic diversity. Species diversity is determined not only by the number of species within a biological community—i.e., species richness—but also by the relative abundance of individuals in that community. … Two communities may be equally rich in species but differ in relative abundance At regional scales, diversity is also increased by speciation and decreased by extinction. These decreases in diversity include those caused by regional extinction events that extirpate species from the region in question but not necessarily from all other regions.Four Types of Biodiversity
Species Diversity. Every ecosystem contains a unique collection of species, all interacting with each other. ...
Genetic Diversity. Genetic diversity describes how closely related the members of one species are in a given ecosystem. ...

Explanation:
Which evidence causes most scientists to believe that seafloor
spreading occurs at the mid-Atlantic Ridge?
А
Oceanic crust is oldest at the ridge.
B
Large sedimentary folds exist in the mantle near the ridge.
Oceanic crust on both sides of the ridge is less dense than
continental crust.
D
Oceanic crust on both sides of the ridge shows matching
patterns of reversed and normal magnetic polarity.
Answer:
Oceanic crusts on both sides of the ridge shows matching patterns of reversed and normal magnetic polarity.
Explanation:
Mid-Atlantic Ridge is a collection of mountains that settle at the bottom of the ocean. These mountains are the result of the movement of the plates. The breakdown of these mountains was very important to give truth to the theory that defended the existence of the expansion of the ocean floor and continental drift. That's because by looking at the mid-Atlantic Ridge, scientists were able to see that the oceanic crusts on both sides of the mid-Atlantic Ridge had patterns corresponding to normal and reverse magnetic polarity. This was the basis for perceiving the movement of the ocean's bottom in random directions.

Cells are created via cell department. And mitosis is an vital a part of this process. Mitosis creates equal copies of cells.
For example, it creates new pores and skin cells to update lifeless pores and skin cells. Interphase has 3 stages: G1, S and G2. During the G1 stage, the cell prepares for department via way of means of growing its mass. During the S stage, the cell synthesizes greater DNA. And at some point of the G2 stage, the cell synthesizes proteins because it keeps to grow. Before it is able to divide, a cell additionally wishes to have its lengthy uncoiled strands of DNA condensed into chromosomes. Otherwise, cell department might be like looking to break up a plate of spaghetti in half. Chromosomes are manufactured from bundles of DNA and protein.

A follow-up experiment revealed that the genetic content of the bacterial cells was altered by the transfer of material from the phage. This process is best described as:
A subsequent investigation uncovered that the hereditary substance of the bacterial cells was modified by the exchange of material from the phage.
Transduction is the interaction by which an infection moves hereditary material starting with one bacterium and then onto the next. Infections called bacteriophages can contaminate bacterial cells and use them as hosts to make more infections.
Lysogeny can change the aggregate, wellness, and advancement of the bacterial host cell. On account of bacterial microorganisms, prophages permit the procurement of new characteristics, for example, destructiveness factors which thusly may work on the host's wellness.
It is the interaction by which phages can bundle any bacterial DNA (chromosomal or plasmid) and move it to another bacterium. The transducing particles of this method of transduction structure when bacterial host DNA is bundled into phage heads rather than viral DNA.

What describes natural rights?
Natural rights are those that are independent of the laws or customs of any particular culture or government, and so are universal, fundamental and inalienable
These rights were bestowed by God and cannot ever be taken away or even ceded. These fundamental natural rights are "life, liberty, and property,"
Human laws cannot nullify them, but an individual can lose the ability to enjoy them by acting in a certain way, like by wrongfully abusing the rights of others.
Natural rights are not generally embraced, in part because of their apparent incoherence and religious connotations.
Some philosophers contend that only legal rights exist and that there are no natural rights; for example, Jeremy Bentham referred to natural rights as "simple nonsense."

What is the net ATP produced during glycolysis ?
Both anaerobic and aerobic conditions can result in glycolysis. Pyruvate enters the citric acid cycle under aerobic conditions and undergoes oxidative phosphorylation, producing a net of 32 ATP molecules.
In the end, glycolysis divides glucose into two pyruvate molecules. Glycolysis can be thought of as having two stages that take place in the cytosol of cells. Due to the use of two ATP molecules, the first phase is known as the "investment" phase, while the second is known as the "payoff" phase. Each of these processes is performed by a different enzyme, with phosphofructokinase serving as the most crucial regulator because it regulates the rate of glycolysis.
Aerobic and anaerobic conditions both result in glycolysis. Pyruvate enters the citric acid cycle and goes through oxidative phosphorylation, which results in the net synthesis of 32 ATP molecules under aerobic conditions. Pyruvate is transformed to lactate in anaerobic environments by anaerobic glycolysis. Two ATP molecules are produced during anaerobic respiration. Cell cytosol is the location of glycolysis.

Where most ATP is created in mitochondria?
Most ATP is produced in the mitochondrial matrix, which is the fluid-filled space inside the inner membrane of the mitochondria.
The process of ATP production in the mitochondria is called cellular respiration. It starts with the breakdown of glucose and other molecules in the cytoplasm by the process of glycolysis, which generates a small amount of ATP. The majority of the ATP is generated in the Mitochondria during the process of oxidative phosphorylation, where the electrons from the breakdown of glucose are passed through a series of protein complexes in the inner mitochondrial membrane, which generates a proton gradient that drives the production of ATP via ATP synthase.
