HYPOTHESIS: If 2 chambers of water are poured side-by-side, the warmer water will mix the cooler layer because it
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.
When are chromosomes present in cells?
A. Just before and during DNA replication
B. Never
Answer:
A
Explanation:
Answer:
prophase, in prophase the mitoic spindle forms and the chromosomes condense. Prophase is the first stage before cell division (mitosis) and chromosomes will be present in the cell.

After the mRNA is formed, what happens?
A. It binds permanently with DNA molecule.
B. It moves out of the nucleus and into the cytoplasm.
C. It disassembles and the process repeats.
Answer:
The correct answer is - B. It moves out of the nucleus and into the cytoplasm.
Explanation:
mRNA formation is known as transcription which is the first process of protein synthesis in which mRNA is formed from DNA sequence with help of RNA polymerase enzyme.
After forming the mRNA sequence this mRNA moves out of the nucleus and reaches the cytoplasm where it performs the second process called translation with help of tRNA and ribosome to produce an amino acid chain.
Answer:
B. It moves out of the nucleus and into the cytoplasm.
Explanation:
After the mRNA is formed, it moves out of the nucleus and into the cytoplasm.

Explique de qué manera la deriva continental ha influido en la distribución de especies vegetales y animales en el mundo.
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).
Justify the claim by describing an example of a behavioral event in ANIMALS that occurs in response to a 24-hour light/dark cycle.
When comparing today's animals to the ones from the Mesozoic era, which is true?
A. only a few of the animals from the Mesozic era are
extinct
B. most of the animals from the Mesozoic era are extinct
C. dinosaurs still roam the Earth
D. all of the animals are still the same
The study of evolutionary relationships that includes a branching pattern showing lineages diverging is called... *
Answer:
Phylogenetic tree
Explanation:
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. The species of interest are shown at the tips of the branches of the tree in question. The branches are connecting with each other, representing the evolutionary history of the species, being the way in which we think that they evolved starting from a common ancestor through various divergence events (when two branches separate).
what are the pro and cons of pollution
Answer:
Cons: Pollution may muddy landscapes, poison soils and waterways, or kill plants and animals. Humans are also regularly harmed by pollution. Long-term exposure to air pollution, for example, can lead to chronic respiratory disease, lung cancer and other diseases What are the pros of pollution?
However, there may be some small advantages to air pollution:
Air pollution helps plants grow. Guess what our factories and cars put in the air? ...
Air pollution slows climate change. Some pollutants we put out heat up the Earth, like carbon dioxide. ...
Air pollution keeps polluted cities cooler in the summer.

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
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'.

Describe what the male beetle has to do In order to successfully mate with the female
Answer: they would maybe have to fight with the other beetles to tr and get the females attention
Explanation:
pls mark brainliest
The male beetle must struggle to successfully mate with the female if where they go there is more than one male courting the female.
How do beetles mate?Female beetles of this species dig tunnels in the dung, where males mate with them. If a male enters a tunnel that is already occupied by a rival, they will fight, trying to pull the other out.
With this information, we can conclude that the male beetle must struggle to successfully mate with the female if where they go there is more than one male courting the female.
