1) Ecosystem that has recovered
2) Ecosystems are altered through the activities of humans.
3) Environmental impact caused by physical factors
4) Ecological niche without competition

Answers

This situation is an example of 'ecosystems are ALTERED through the activities of humans' (Option 2).

Human activities (i.e., anthropogenic activities) represent the main factor capable of affecting the homeostasis of the ecosystems.

Some human activities that negatively alter a natural ecosystem include deforestation for different purposes (e.g., urbanization, agriculture, etc), the introduction of non-native invasive species, pollution, etc.

These activities may trigger serious problems to the environment such as soil erosion, climate change, undrinkable water, etc.

In conclusion, this situation is an example of 'ecosystems are ALTERED through the activities of humans'.

Horses and donkeys can breed and produce sterile offspring known as mules. Horses and donkeys remain separate species because of this hybrid sterility, which is a(n) Group of answer choices post-zygotic barrier to reproduction. sympatric barrier to reproduction. pre-zygotic barrier to reproduction. allopatric barrier to reproduction. good thing.

Answers

Answer:

The correct answer is ''post-zygotic barrier to reproduction''

Explanation:

Biological barriers prevent the exchange of genes between two or more populations, a postzygotic reproductive barrier reduces the survival or reproduction of hybrid offspring. In hybrid non-viability there is low survival of the hybrid, especially during embryonic stages. On the other hand, the sterility of the hybrid occurs when the fertilized egg develops into a healthy but sterile adult. Segregation of aneuploid gametes during meiosis, different gene associations occur on the chromosomes of the parents.

A phylogenetic tree is a tree that is responsible for showing the different relationships with respect to evolution between species that are considered to have a common offspring.

Explique de qué manera la deriva continental ha influido en la distribución de especies vegetales y animales en el mundo.

Answers

Answer:

la deriva continental ha notablemente influido en la distribución actual de las especies. Este fenómeno se puede observar en grupos de organismos similares que se encuentran en diferentes continentes, lo cual concuerda con la idea de que la separación entre dichos continentes se produjo más tardíamente en el tiempo  

Explanation:

La teoría de la deriva continental plantea que durante el final del Paleozoico y el principio del Mesozoico (hace aproximadamente hace 225 millones de años) las masas continentales actuales se encontraban unidas formando una gran masa de tierra o supercontinente conocido como 'Pangea'. Esta teoría se basa en evidencia de diversa fuentes incluyendo pruebas geográficas (coincidencias en las costas de algunos continentes), paleontológicas (mismos fósiles en diferentes continentes), geológicas y tectónicas (por ej., la presencia de cadenas montañosas que se separaron hace millones de años), y paleoclimáticas (evidencia de climas similares durante el pasado en continentes diferentes). La deriva contiental afectó la distribución actual de especies de plantas y animales. Por ejemplo, la fauna en Europa es semejante a la observada en Norteamérica porque estos continentes se separaron más tardíamente en el tiempo que otros contientes/masas de tierra del hemisferio sur, y dichas semejanzas se encuentran reflejadas en organismos evolutivamente más relacionados (menor tiempo de divergencia evolutiva).

HYPOTHESIS: If 2 chambers of water are poured side-by-side, the warmer water will mix the cooler layer because it

Answers

Answer:

The warmer water will mix with the cold water because it will migrate to the surface.

Explanation:

If hot water and cold water are poured in the same place, it means that they will occupy the same space. However, hot water has a lower density than cold water, which means that hot water molecules are lighter and will tend to rise towards the surface.

However, when migrating to the surface, the hot water molecules will pass between the cold water molecules, causing the two waters to mix. In this process, the hot water will transfer heat to the cold water and cool until the two waters have the same temperature.
