En un bosque oscuro, ¿qué variación de la polilla salpicada se reproduciría en
mayor número? En este escenario, la variación
de la polilla moteada
se reproduciría en mayor número debido a.
Answer:
Condiciones ambientales adecuadas.
Explicación:
La variación de la polilla moteada se reproduciría en mayor número debido a las condiciones ambientales adecuadas. El color oscuro del bosque ayuda a la polilla moteada a esconderse de sus depredadores que se alimentan de ellos y provoca la disminución de la población de polillas. Es un proceso de selección natural en el que la polilla de color oscuro sobrevive y aumenta la población debido al color oscuro del bosque, mientras que la población de polilla de color claro disminuye debido a la alta depredación.

Melting ice sheets increase the volume of water in the oceans and reduce the salinity of water. How would this affect:
a) sea animals in polar regions?
b) coastal areas already at sea level?
Answer:your answer is B
Explanation:
In the polar regions if the water goes onto shore it would freeze adding to the icy land and giving sea animals an advantage as all the sea animals would be at the to of the sea level giving a better attack on prey. as in Coastal area it would flood the area causing and flood.

Explain why a topographic map has a key.
Topographic maps represent the locations of geographical features, such as hills and valleys.
What do you mean by topographic maps?Topographic maps use contour lines to show different elevations on a map. A contour line is a type of isoline; in this case, a line of equal elevation.
In modern mapping, a topographic map or topographic sheet is a type of map characterized by large-scale detail and quantitative representation of relief features, usually using contour lines.
A topographic map is a detailed and accurate illustration of man-made and natural features on the ground such as roads, railways, power transmission lines, contours, elevations, rivers, lakes.

Volcanoes form most commonly in regions where one tectonic plate plunges beneath another tectonic plate. How does this process
lead to volcano formation?
OA. The plate plunging downward suddenly turns upward, breaking through the surface to form volcanoes.
OB. The plate plunging downward knocks loose part of the Earth's core, which rises up to form volcanoes at the surface.
OC. It causes strong earthquakes, which shake the ground upward into the shapes of volcanoes.
OD. It causes part of the overriding plate to melt into magma, which rises up to form volcanoes at the surface.
Answer:
OD is the correct answer
Answer:
The answer is
OD. It causes part of the overriding plate to melt into magma, which rises up to form volcanoes at the surface.

What landscape feature contributes to the dryness of deserts?
O Desert canyons collect all water and funnel it out of the desert.
O Mountains block the winds that bring rain clouds.
O The open, flat areas of a desert prevent clouds from forming.
O Desert lakes absorb all the water.
Answer:
Deserts are areas that receive very little precipitation. ... Others are dry expanses of rock, sand, or salt flats. ... air hinders the formation of clouds, so very little rain falls on the land ... In fact, the Atacama Desert is the driest place on Earth. ... With little vegetation to block it, the wind can carry sand and dust
Explanation:
i hope this help

C.The open, flat areas of a desert prevent clouds from forming.
What would happen to zygote if the egg and sprem cells weren't formed with the correct number of chromosomes?

Which earthquake wave travels the fastest and arrives first?
a) S-wave
b) tension wave
c) P-wave
d) shear wave
Answer:
C) P-wave
Explanation:
P waves travel the fastest and are the first to arrive from the earthquake. In S or shear waves, rock oscillates perpendicular to the direction of wave propagation. In rock, S waves generally travel about 60% the speed of P waves, and the S wave always arrives after the P wave.

predict the effect of reintroducing wolves into the park on the coyote, grass and raven populations.
Answer:
Wolves and coyotes will compete for resources and the coyote population will decrease and wolves might decrease from competition as well. The increase of predators (wolves and coyotes) will cause the raven population to go down. If the raven eat grass then the grass population will go up becuase more ravens are getting eaten= no one eating grass.
Explanation:
Answer:
The amount of grass increases. The amount of coyotes decrease. The amount of ravens increase.
Explanation:
Wolves and coyotes will compete for resources and the coyote population will decrease. The increase of dead deers caused by the increase of the wolf population will cause the raven population to increase and the amount of grass to increase.

While investigating applications of science knowledge, Willy learned that scientists have used genetic engineering techniques to attach insulin-producing genes to bacterial DNA. These bacteria produce large amounts of scarce human hormones. Scientists predict that hormones produced by bacteria will be inexpensive and will not cause allergic reactions. (SC.7.N.1.5) Scientists developed hormone-producing bacteria because they wanted to
Answer:
develop methodologies to increase the production of hormones for human use
Explanation:
Genetic engineering refers to the manipulation of an organism's genes by using recombinant DNA (rDNA) techniques in order to develop biotechnological and biomedical applications. For this purpose, genetically engineered bacteria carrying recombinant human genes can be used for producing human hormones. For example, recombinant human insulin can be produced by using Escherichia coli strains, and this hormone can then be purified as genetically engineered bacteria grow in order to treat diabetic patients. For this purpose, a bacterial plasmid (i.e., an independent fragment of circular bacterial DNA) is cut with restriction enzymes and then the human gene encoding the hormone of interest is inserted into the plasmid. Finally, the genetically modified plasmid may be readily transferred to the bacterial chromosome and thus increase the supply of the hormone of interest for its use by humans.
