Explanation:
Describe the movement of Earth’s mantle. Explain how convection currents can cause tectonic plates to move.
Answer:
Heat rising and falling inside the mantle creates convection currents generated by radioactive decay in the core. The convection currents move the plates. Where convection currents diverge near the Earth's crust, plates move apart. Where convection currents converge, plates move towards each other.
Convection currents from core radioactive decay rise and fall in the mantle. Convection currents move plates. Plates separate near convection currents. Plates converge at convection currents.
What are convection currents?Convection currents are caused by differential heating. Warm, less dense, lighter material rises while cool, more dense, heavier material sinks. Convection currents are patterns of circulation that are produced by this movement in the Earth's mantle, oceans, and atmosphere.
Convection currents are produced by radioactive decay in the core and are caused by heat rising and falling inside the mantle. The plates are moved by convection currents. Plates separate where convection currents split close to the Earth's crust. Plates move in the direction of one another where convection currents converge.

Which of these statements best describes the connection between biodiversity and evolution?
The more biodiversity an area has, the greater the chances of new species arising.
If biodiversity is high, then more predation will take place, preventing species from evolving,
Without a lot of biodiversity, organisms are more likely to survive, so they have more time to adapt.
Evolution depends upon low biodiversity to keep population sizes down, which increases numbers of genes.

When geneticists cut genes from one organism and insert them into the DNA sequence of another organism, the process is called
The cutting of genes from one organism and inserting them into the DNA of another organism is called genetic engineering.
What is genetic engineering?It is the process of using rDNA or recombinant DNA technology to change the genetic makeup of an organism. The humans have manipulated genomes indirectly traditionally by selecting offsprings with desired traits and controlling breeding.
The process involves direct manipulation of one or more genes. Generally, in the process, a gene from another species is supplemented to the genome of another organism to give it a desired phenotype.
Thus, the process is called genetic engineering.

Which statement explains why secondary succession is generally more rapid than primary succession?
An area of secondary succession has never been colonized.
There are no competing organisms in secondary succession.
The soil is already present at the start of secondary succession.
Pioneer species in secondary succession include bacteria.
Answer:
The soil is already present at the start of secondary succession.
Explanation:
Secondary succession is usually faster than primary succession because soil and nutrients are already present due to 'normalization' by previous pioneer species.

A scientist lists the characteristics of an organism that he is observing
It is multicellular
It has cell walls made of cellulose,
It makes its own food,
In which of these Kingdoms should the organism be classified?
Animalia
Archaea
Fungi
Plantae
A scientist lists the characteristics of an organism which he is observing. This organism should be classified under the kingdom Plantae. Thus, the correct option is D.
What is Plantae?The living organisms on the planet are divided into five different kingdoms including Monera, Protista, Fungi, Plantae, and Animalia are classified on the basis of their characteristics such as the cell structure, mode of nutrition, mode of reproduction and the body organization.
Kingdom Plantae is a kingdom of the five kingdom classification given by R. H. Whittaker. Plants include green, brown and red algae, liverworts, mosses, ferns and the seed plants with or without the formation of flowers. They have the characteristics including multicellular organisms, covered with a cell wall made up of cellulose, are autotrophs (make their own food), contain photosynthetic pigment in plastids.
Therefore, the correct option is D.
