Answer:

The gradual replacement of one plant community by another through natural processes over time.

Explanation:

Succession is a process dominated by plants, in which communities change as a function of the changes experienced by plant communities, that is, it is the natural evolutionary process by which some species gradually take the place of others less adapted to the environment. Ecological succession tries to predict the changes that occur in ecosystems over long periods of time, that is, the temporary directional change in the composition or structure of a community  over time.

Ectotherm describes the animals that use external sources to maintain their body temperature. They will maintain their homeostasis in cold weather by sitting on a warm surface. Thus, option A is correct.

Ectotherms are animals that cannot regulate their body temperature on their own and are dependent on external sources to maintain their body heat.

They have to depend on environmental sources like a warm place to maintain their body temperature during the cold weather. They cannot sweat or shiver to maintain homeostasis.

Therefore, during the cold, ectothermic animals sits on warm surfaces to maintain homeostasis.

The statements that accurately describe fermentation are cells may convert pyruvic acid to lactic acid, and fermentation is an anaerobic process. The correct options are B and D.

Fermentation is an anaerobic chemical process that breaks down molecules like glucose. More specifically, fermentation is the bubbling that happens during the creation of wine and beer, a procedure that has been around for at least 10,000 years.

It is different from aerobic respiration because it occurs in the absence of oxygen and aerobic respiration occurs in the presence of oxygen. The product of fermentation is lactic acid, which is produced from pyruvic acid.

Thus, the correct options are: B, Cells may convert pyruvic acid to lactic acid, and D, Fermentation is an anaerobic process.

Answer:

"Plate movement is thought to be driven by a combination of the motion of the seafloor away from the spreading ridge (due to variations in topography and density of the crust, which result in differences in gravitational forces) and drag, with downward suction, at the subduction zones."

Explanation:

Does this help?

It is because of ridge slip and slab slide i the divergent plate boundaries, where tectonic plates movement creates mid ocean ridges.

Divergent plate boundaries are the regions where the tectonic plates are diverging from one another, this is known as a divergent plate boundary. Above upward convection currents, this happens.

The lithosphere's base is pushed upward by the rising current, which lifts it off the ground and flows lateral currents beneath it. When an oceanic lithosphere border diverges, the rising convection current beneath raises the lithosphere, creating a mid-ocean ridge.

The plate material above is dragged along in the flow direction by this lateral flow. The overlaying plate is thinned out, fractures, and pulls apart at the peak of the uplift.

Hence, in fact it is not by the gravitational pull but by the ridge slip.

Answer:

Life on Earth goes back almost 4.1 billion years, but photosynthesis as characterized by cyanobacteria only appeared around 3.5 billion years ago (Ga). Since life on Earth predates photosynthesis, the exploration of this deep-water environment that lacks any source of light could provide information on what those life forms looked like.

Explanation:

This was the answer on edge

The major reason for exploring the mid-Cayman ridge is to provide

information on what those life forms looked like.

This is the process in which plants manufacture their food in the presence

of sunlight and other compounds.

The mid-Cayman ridge which is present in a deep water environment has

Contact inhibition is a process of arresting cell growth when cells come in contact with each other. As a result, normal cells stop proliferating when they form a monolayer in a culture dish. Contact inhibition is a powerful anticancer mechanism that is lost in cancer cells

Contact inhibition is the property of normal healthy cells where the cells cease growth after coming in contact with each other. A lack of this property results into uncontrolled growth of cells.

Contact inhibition is the property of normal healthy cells which enables the cells to cease proliferation and growth when they come in contact with each other. This property is lost by the cell when the cells undergo malignant transformation. As a result, this leads to uncontrolled proliferation and solid tumor formation in the body.

In the in-vivo culture of cells, contact inhibition arrests cell growth and as a result, normal cells stop proliferating when they form a monolayer in the culture dish. Contact inhibition is a powerful anticancer mechanism which is lost in cancer cells.

Explanation:

i live in Nebraska

The oldest known species of horse found in Knox County in Nebraska, Eohippus, (genus Hyracotherium), also called dawn horse, is considered as oldest known species of horse, hence option 1 is correct.

The horse is a mammal considered a domesticated one-toed, hoofed mammal and belongs to the taxonomic family of Equus ferus, there is only one species of a domesticated horse but around 400 breeds developed for the improvement of their strength.

All horses are considered grazers, food like grasses and plants, and believed as herbivores in the tropic level, only plants not animals.

These animals generally use for domestication purposes by human beings for pulling carts and heavy materials.

Therefore, in Knox County of Nebraska, the oldest known species of horses is found, hence option 1 is correct.

Answer: endothermic reaction.

Explanation: A chemical reaction that stores energy is called an endothermic reaction. More energy might be released as products form than the energy needed to break the reactants apart.

Chemical reactions which release energy are called Exothermic reaction whereas the reaction which store energy are called Endothermic reaction. The energy is stored in the form of chemical bonds.

A chemical reaction is a process in which chemical transformation of one set of substance is converted into another type of substance.

Chemical reactions are of two types on the basis of energy transfer: Exothermic reaction and Endothermic reaction. An exothermic reaction is the chemical reaction in which the product is formed with the release of energy in the form of heat. For example: Breakdown of glucose through cellular respiration. An endothermic reaction is the chemical reaction in which the product is formed which stores energy in the form of chemical bonds. For example: The formation of glucose.

Answer:

The no. of heterozygous carriers = 0.0392

Explanation:

From the given information:

The incidence of this recessive disorder i.e. q² = 1/2500

q² = 0.0004

q = 0.02

From Hardy Weinberg's Equilibrium.

p + q = 1; &

p² + 2pq + q² = 1

∴

p + 0.02 = 1

p = 1 - 0.02

p = 0.98

So, the numbers of heterozygous carrier 2pq is:

= 2 × 0.98 × 0.02

= 0.0392
