What trait would make an individual likely to survive and reproduce in a pest population that feeds on pest-resistant plants?

Answers

Answer:

Upon exposure to insecticides, insects that do not carry the resistance genes die, thus allowing the individuals with the resistance genes to survive and reproduce, creating more resistant insects. With every generation the number of resistant insects increase.

Explanation:

The trait that would make an individual ( pest ) survive in a pest population that feeds on pest-resistant plants is :  Possession of Pesticide resistant genes

In a pest infected population most pests can be eliminated with the use of pesticides. therefore when pesticides are administered in the population, the pests that posses genes resistant to pesticides will survive and continue their reproduction cycle.  while pests without pesticide resistant genes will be eliminated.

Hence the trait that a pest( individual ) should posses to survive in a pest population is; the Possession of Pesticide resistant genes .

Which of the following is a possible path for carbon to cycle through an ecosystem?

1. Atmospheric CO2 -> animals -> factories -> fossil fuels -> plants

2. Atmospheric CO2 -> factories -> fossil fuels -> animals -> plants

3. Atmospheric CO2 -> plants -> animals -> fossil fuels -> factories

4. Atmospheric CO2 -> fossil fuels -> factories -> animals -> plants

Answers

Answer: 3. Atmospheric CO2 -> plants -> animals -> fossil fuels -> factories

Explanation:

The carbon cycle is one of the types of biochemical cycles in which carbon is recycled in atmosphere, biosphere, lithosphere, and hydrosphere in various forms. The atmospheric carbon dioxide is absorbed by the plants and they utilize it as reactant for the process of photosynthesis in which they synthesize their own food. These plants are consumed by animals further when these plants and animals die their remains form fossil fuels deep beneath the earth crust. It takes about millions of years for fossil fuels to form in the sedimentary rocks. The fossil fuels are utilized by the factories to run their machines. Again when fossil fuels burn they emit carbon dioxide gas in the atmosphere.

En los seres vivos acuaticos el oxigeno es tomado del __________ y penetra a la celula por el fenomeno de ___________

Answers

Answer:

En los seres vivos acuáticos el oxigeno es tomado del agua y penetra a la célula por el fenómeno de respiración branquial.

Explanation:

La respiración es el proceso mediante el cual los seres vivos obtienen oxígeno.  Es decir, la respiración implica el reemplazo del dióxido de carbono en los pulmones por oxígeno del aire, y puede ser pulmonar, branquial, traqueal o cutánea.

La respiración branquial es un tipo de respiración propia de la mayoría de los animales acuáticos y se lleva a cabo en las branquias, unas estructuras con forma de láminas que contienen vasos sanguíneos. Los animales acuáticos dispone de estos órganos que permiten absorber el oxígeno que se encuentra en el agua y eliminar el dióxido de carbono.

El agua que entra por la boca y circula por las branquias, donde el oxígeno es absorbido, pasa a la sangre y es transportado a todo el cuerpo donde se produce una respiración celular.

Es decir, en los seres vivos acuáticos el oxigeno es tomado del agua y penetra a la célula por el fenómeno de respiración branquial.

Explain how a concentration gradient, a membrane protein, and hydrogen ions work together to provide a mithochondrion with energy.

Answers

Answer:

Mitochondria within the electronic transport chain, are responsible for producing the energy that the cell needs, adjusting its operation to meet the metabolic needs of the body.The mitochondrion is the place where oxygen is consumed from aerobic organisms through various electron carriers and proton translocators (H +).

Explanation:

The lipid matrix of the membrane provides an impermeable barrier to ion translocation, as well as a topological organization to the catalysts in the membrane matrix that allows them to transport both e- and ions within and across the membrane in vector form. The transformation of oxidative energy into other forms of energy is carried out, initially, by generating a transmembrane electrochemical potential difference of H + ions (protomotive force). This force is the product of the asymmetric distribution of H + on both sides of the membrane, as those are translocated through it by the enzymatic complexes of the respiratory chain.The protomotive force is made up of two closely related components: one, function of the difference in chemical concentration of hydrogens across the membrane (a pH gradient) and another, dependent on the difference in electrical charge of H + ions on both sides of it (an electrical potential gradient). Gradients of electrical charge and chemical potential produce a field in which a force is exerted that tends to attract previously expelled protons into the mitochondria. It is the enzymatic complex of ATPase, the means by which the thermodynamically reversible translocation of H + ions is catalyzed. At the same time, the chemical activity of the H + on both sides of the membrane causes a change in the equilibrium constant of the enzyme, inducing it to catalyze the synthesis of ATP.

Some minerals are evenly distributed around the planet, while other minerals are quite rare. Why are some minerals so rare and unevenly distributed?


A. Certain minerals form only under high heat and pressure that develop near volcanoes.

B. Certain minerals form only in Earth's crust, so they are difficult to locate.

C. Certain minerals form only in specific climates, and not all climates, are the same around the world.

D. Certain minerals form only in the extreme heat found at the bottom of lakes and rivers.

Answers

Answer:

C

Explanation:

Minerals, fresh water, and biosphere resources are distributed unevenly around the planet as a result of past geologic processes. ... Mineral, fresh water, ocean, biosphere, and atmosphere resources are limited, and many are not renewable or replaceable over human lifetimes.

The option (C) is correct. Certain minerals form only in specific climates, and not all climates, are the same around the world.

What are minerals?

A mineral is a naturally occurring inorganic element or compound having an orderly internal structure and characteristic chemical composition, crystal form, and physical properties. Common minerals include quartz, feldspar, mica, amphibole, olivine, and calcite.

Moreover, the major minerals, which are used and stored in large quantities in the body, are calcium, chloride, magnesium, phosphorus, potassium, sodium, and sulfur. The trace minerals are just as vital to our health as the major minerals, but we don't need large amounts.

Therefore, economic minerals are used in a wide range of applications related to construction, manufacturing, agriculture and energy supply. Economic minerals include: Energy minerals used to produce electricity, fuel for transportation, heating for homes and offices and in the manufacture of plastics.

Example: Speckled moths camouflage with the bark of trees and are not easily seen by predators. Black moths do not camouflage with the bark of trees and are easily seen by predators, therefore the black moths are eaten. Because the black moths have been eaten they cannot reproduce and pass on the trait for black wings to their offspring, but the speckled moths are able to reproduce because they survived and are able to pass on the speckled wing trait to their offspring.
