How does energy affect competition in a rainforest?
Answer:
Energy affects competition in the tropical rainforest due to the dense population of trees found in this region.
Trees are producers and they compete mainly for water, sunlight and nutrients. Sunlight provides the source of solar energy which is instrumental in its photosynthetic process.
The trees form canopies and create competition among the ones who have lower stems and branches while the ones with longer stems continue to grow taller due to the availability of sunlight.
Competition may also affect the organisms living in this region as they compete for food.

What are the main characteristics of amphibians?
Answer:
Amphibians are small vertebrates that need water, or a moist environment, to survive. The species in this group include frogs, toads, salamanders, and newts. ... The larvae are aquatic and free-swimming—frogs and toads at this stage are called tadpoles. At a certain size, the young develop limbs and lungs.

A gene exists in two different forms (A and a). With respect to the allele present, which type of gamete(s) can a homozygous recessive individual produce?
a
A
Aa
A and a
Answer:
a
Explanation:
in the words, 'homozygous recessive', the root 'homo' in 'homozygous' means 'same' so that means that a two different alleles can not come from this individual. the word 'recessive' when referring to alleles means it is the submissive (opposite of dominant) or little lettered allele. therefore, this individual will only be able to pass on a recessive allele which is, in this case, 'a'.

Identify the large brown tectonic plate and whether it is oceanic or continental
Answer
Pacific Plate, oceanic tectonic plate
Explanation:
the large brown plate is pacific plate was under the ocean and also named after the ocean pacific ocean. so it is easy to guess
hope you understood it . it was my explanation up for more info down i have pasted what they told in google.
Pacific plate
In fact, six of the seven major tectonic plates are named after the continents they contain. The one exception is the Pacific plate, which lies beneath the Pacific Ocean. Not only is this the only major tectonic plate that is mainly underwater, it is also the largest, spanning over 100 million square kilometers.
Pacific Plate. The Pacific Plate is an oceanic tectonic plate that lies beneath the Pacific Ocean. At 103 million km2 (40 million sq mi), it is the largest tectonic plate. The Pacific Plate contains an interior hot spot forming the Hawaiian Islands.
Read the article and use the information to answer the question that follows. Changing Theories Explain Lamarck's ideas about how organisms changed over time.
Answer:
Lamarck thought that organisms came into being through spontaneous generation
He thought they changed from simple organisms to more complex organisms because they had an innate drive to become more complex and perfect
Lamarck thought that when organisms changed their behaviors in response to a changing environment, their bodies changed. When they used a part of their bodies more, it changed accordingly. When they used a part of their bodies less, it shrank

The populations living on a rough, steep mountain would have a higher rate of
speciation than those living in a large, open grassland because the mountain
would
A. show less habitat fragmentation
B. provide its populations with more resources
C. isolate populations into subgroups
D. have fewer niches for organisms
Answer:
The correct answer is option C, that is, have a wider range of environments.
Explanation:
It has been known that geographic isolation is a general way for the initiation of the process of speciation, like the rise of mountains, rivers changing course, migration of organisms, continental drift, due to this what was once a steady population gets differentiated into two or more kinds of smaller populations.
A mountain range, due to distinctions in temperature and precipitation as a result of different altitudes, can lead to a higher rate of speciation. Due to these differences, a single mountain range can exhibit an enormous array of biodiversity and climate zones.
In comparison to populations living in broad, open grasslands, populations living on rocky, steep mountains would experience a higher rate of speciation due to the mountain's ability to divide populations into smaller subgroups . So, the correct option is C.
How the population have higher rate of speciation?Geographic isolation is known to be a common way for the beginning of the process of speciation, similar to the formation of mountains, the alteration of rivers, the migration of organisms, and continental drift. As a result, what was once a stable population becomes divided into two or more different kinds of smaller populations.
A mountain range might result in a greater amount of speciation because to differences in precipitation and temperature as a result of various altitudes. A single mountain chain can display a huge variety of biodiversity and temperature zones as a result of these variances.
Therefore, the correct option is C.
