The decreasing wolf populations in North America can result to the <span>range expansion of coyotes
</span><span></span>Wolves and coyotes usually compete for prey, especially the smaller mammals. Wolves do not actively hunt coyotes but do attack them when the latter ventures into their territory.
With decreasing wolf populations, coyotes can then venture and hunt more freely. However, the coyotes cannot take the place of the wolves in helping maintain balance in the ecosystem in which they belong to because of their preference for smaller mammals.
Wolves can help regulate an ecosystem's larger mammals such as the ungulate populations, as they do not prey on the smaller mammals as much as coyotes do. This leaves more prey available for mid-level carnivores like foxes. Moreover, wolves also leave behind carcasses of their prey, which become food for other animals such as <span>foxes, badgers, raptors, coyotes and other scavengers.</span>
Answer:
Eubacteria and Archaebacteria
Explanation:
Prokaryotes are single-celled organisms that do not have a nucleus
Eukaryotes are typically multicellular, but definitely do have a nucleus
Eubacteria and Archaebacteria DO NOT have nuclei
Fungi (think mushrooms) and Protists do have nuclei- and belong to the Eukaryote group- which means they DO have nuclei
Answer: a) relies on the uptake of an external signal molecule from the cell
Explanation: Signal transduction is known as the transmitting of any signal of a molecule from exterior of cell to interior of cell.This technique is termed as critical is taken care of successful transmission of signal effectively and positive result and reception is done by the cell surface receptors.It is also known as cell signalling. Thus,option(a) is the correct option of all.

Answer:
La recesión provoca un aumento en el gasto público del gobierno para hacer que la economía flote hasta que haya estabilidad. Esta es una característica común en la economía y, como tal, ayuda a amortiguar el efecto de una recesión. Se perderán muchos empleos, aumentando así los niveles de desempleo. Por lo tanto, el gobierno tiene que gastar más para ayudar a los afectados a sobrevivir.
Explanation:
Una alta tasa de desempleo y las malas condiciones económicas llevan al gobierno a un mayor gasto durante el tiempo de recesión. El propósito es ayudar a estimular la economía y ayudarla a sobrevivir las dificultades económicas. Un ejemplo típico es el paquete de estímulo de Obama en los Estados Unidos de América en 2009 en respuesta a la gran recesión.
