When do greenhouse gases cause global warming

Answer:

1. 20 units

2. 4 units

Explanation:

In an ecosystem, energy is transferred from one organism occupying a trophic level to another as they feed on one another. The amount of energy that is being transferred as the chain progresses is called ECOLOGICAL EFFICIENCY. According to this question, the ecological efficiency at each trophic level of the ecosystem is 20%. This means that about 20% of energy units will be transferred to the next trophic level.

If the green plants of the ecosystem capture 100 units of energy, the amount of energy that will be available to support herbivores (plant eaters) is: 20% × 100units i.e. 20/100 × 100 = 20 units.

Also, the amount of energy that will be available to support carnivores subsequently will be 20% of 20 units i.e. 20/100 × 20 = 4 units.

Answer:

Incomplete dominance.

Explanation:

In this scenario, a white splashed (Bl/Bl) Andalausian chicken and a black (bl/bl) Andalusian chicken are crossed. The heterozygotes produced show an intermediate phenotype (blue). Thus, the inheritance pattern this would be indicative of is an incomplete dominance.

Answer:

Punnet square

Explanation:

I am pretty sure this is it

By using Punnett square we can determine the probability that an organism's expressed version of a trait will be passed on to its offspring.

Reginald. C Punnett invented the Punnett square, a square shape diagram used to forecast the genotype and phenotype of offspring from a breeding experiment by crossing the genes of the parents.

The diagram's number of Punnett squares is determined by the number of attributes employed. After creating the boxes, one parent's gene is placed on top and the other parent's gene is placed on the left side.

In the event of a monohybrid cross, just one letter with a single characteristic crosses one box, whereas two letters with two separate traits cross one box.

The number of alternative genotypes of offspring is obtained by crossing the characteristic.

Thus, the Punnett square helps in determining the probability that a trait will be passed on to its offspring.

Answer:

Most plants have green leaves, where the photosynthesis happens. When those sugars are made, they need to be given to every cell in the plant for energy. Enter phloem. The phloem cells are laid out end-to-end throughout the entire plant, transporting the sugars and other molecules created by the plant.

C: Afectan principalmente a nuestro sistema nervioso central

Explanation:

Al ingerir sustancias adictivas, el principal afectado o influenciado es el sistema nervioso. Aunque existen diversas formas de acción de las  sustancias adictivas, en general, éstas actúan afectando el pasaje dopaminérgico.  

La dopamina es un neurotransmisor liberado por el sistema nervioso central que causa sensación de placer. Es conocido como la "hormona del placer" y esta relacionado con la evolución de las adicciones. Las diversas sustancias adictivas alteran el funcionamiento normal del sistema nervioso, provocando un exceso de liberación de dopamina. Esta excesiva sensación de placer al consumir sustancias adictivas es lo que nos lleva a seguir consumiendo, para repetir la experiencia placentera, generando adicción. Al hacerlo, los mecanismos de recompensa del cerebro se ven afectados, siendo la causa del elevado nivel de dopamina en el organismo. Este aumento anormal del neurotransmisor provoca una respuesta de parte del organismo que radica en disminuir la cantidad de receptores dopaminérgicos. Al hacerlo, la persona adictas sienten menos placer y mas necesidad de consumir sustancias, para alcanzar el mismo efecto de euforia o uno incluso superior.

3. Spiral galaxies revolve around a single point and gas spinning arms of stars extending from the center

4. Star 4 will stay on the main sequence for the longest time.

Explanation:

A galaxy is a system of gases, dust, and billions of stars and their solar systems, and dark matter which are bound together by gravity. Types of galaxies based on structure are elliptical, spiral, irregular and barred spiral.

Spiral galaxies have a spiral shape consisting of a central bulge, a halo, a disk, and spiral arms. At the center of revolution of the galaxy is the bulge which contains older stars. The disk contains gas, dust and younger stars which extend as spiral arms. The halo is found around the bulge and contains old cluster of stars. Ab example of a spiral galaxy is our Milky Way galaxy.

4. The mass of a star is related to its luminosity as well as its position on the main sequence. High solar mass stars have high luminosity and therefore spend the least time on the main sequence whereas low solar mass stars have low luminosity and spend the most time on the main sequence.

Therefore, Star 4 having the lowest solar mass will spend the most time on the main sequence.

Explanation:

Answer:

As the human population has grown, the need for more land has caused an increase in the cutting down of forest lands for habitation and farming. The result has been an increase in soil erosion, an increase in species extinction from habitat loss, and a reduction of oxygen supplied by the trees, as well as lower amounts of carbon dioxide being removed from the atmosphere. Industrial and personal use of fossil fuels has dramatically increased the amount of air pollution in the atmosphere while systematically using up the supply of the non-renewable resources such as coal, oil and natural gas
