Symaptric speciation is the formation of new species in populations that live in the same geographic area, while allopatric speciation occurs when the population is separated by a geographcial area. So, according to this: The difference between the sympatric speciation and the allopatric speciation is that sympatric speciation involves a behavioral barrier, while allopatric speciation involves a physical barrier.

Explanation:
What processes are responsible for the formation of copper ?
Answer:
The high temperatures of volcanic magma creates hydrothermal veins, allowing some of the heat to escape near the upper layers of the Earth's crust. This is why copper is often found in the sedimentary layer, where sand and mud are compressed until they form a layer of sedimentary rock on the surface of the earth

The first part of the small intestine is called duodenum
Explanation:
The small intestine is a tightly folded tube which connects to the stomach on the top end and to the large intestine on the bottom end.
The small intestine consists of three parts:
duodenumjejunum (absorbs sugars, amino acids, and fatty acids)ileum (absorbs remaining nutrients that did not get absorbed by the duodenum or jejunum)Duodenum is responsible for completing the first phase of digestion. In this section of the intestine, food is mixed with enzymes and bile which help break down food.
Answer:
Duodenum
Explanation:
Duodenum is the first part where most of the small intestine digestion happens

Are gender traits completely a result of societal expectations?
No, Gender traits are not as a result of societal expectations. They are as a
result of biophysical processes in the body.
Both genders have their unique chromosomes composition in which
Males have XY.Females have XX.During reproduction, the male sex cell passes either the X or Y chromosome
to the offspring while the female pass only the X chromosomes.
This depicts that the male sex cells which is the sperm is the main

Find the remainder when p(x) = –2x5 + x4 + 5x3 + 4x + 1 is divided by (x - 2).
The remainder when p(x) = -2x⁵+x⁴+5x³+4x+1 is divided by (x-2) is 1.
To solve the question above, we make use of the remainder theorem.
Remainder Theorem: It states that if a function F(x) is divided by (x-a), the remainder is F(a).
From the question,
Given:
Dividend ⇒ p(x) = -2x⁵+x⁴+5x³+4x+1Divisor ⇒ (x-2)in view of the above and applying the Remainder theorem, The remainder will be p(2)
p(2) = -2(2⁵)+2⁴+5(2³)+4(2)+1p(2) = -64+16+40+8+1p(2) = 1hence the remainder when p(x) = -2x⁵+x⁴+5x³+4x+1 is divided by (x-2) is 1

What are some similarities and differences between an angiosperm and a gymnosperm? PLEASE
Answer:
Here are some similarities and differences
Explanation:
Both are more highly evolved than nonvascular plants, both are vascular plants with vascular tissue that live on land and reproduce by making seeds, both are classified as eukaryotes
Only angiosperms are known as flowering plants, many have blossoms and fruits that contain seeds and the typically drop their leaves when the seasons change their leaves are flat and are seasonal in their life cycle
Gymnosperms produce uncovered seeds, most have green needle-like leaf structures, they are generally evergreen

Explanation:
A typical leaf is composed of multiple layers of specialized cells. What is the correct order of layers starting on the upper surface of the leaf and progressing to the lower surface?
Answer: cuticle - epidermis - palisade mesophyll - spongy mesophyll- epidermis - cuticle
Explanation:
Briefly summarize the structure of moss.
Mosses are bryophytes, primitive plants believed to be among the first to develop the ability to live on land. Moss plants have no vascular tubes to transfer water or nutrients, and no true stems or roots. Environmental water sources and absorption limit moss plant size.
There may be as many as 15,000 species of mosses. Although unique species of moss grow in dramatically different habitats across the planet – from the arctic to the desert – all have basically the same structure.
Basic Moss SporesThe initial moss plant is a spore given off by the sporophyte that forms at the end of the moss plant’s “stem.” Released spores travel long distances on the wind and may remain viable for decades. Moss spores landing in suitable conditions divide and produce hairy filaments called protonemas, which are like thin plant threads that weave across the growing medium. Sprouting from the spore filaments, gametophytes form, held to the surface by rhizoids.
Main Structure of MossThe main moss structure is the gametophyte, which functions like a moss’s “stem” and “leaves.” A moss "stem" is called the axis, and this part of the moss supports leaf-like structures.
Phyllids are the leaf-like structures that carry out photosynthesis, transforming sunlight into sugars the moss uses for food. Typically arranged in a spiral, moss “leaves” are usually one cell thick with ribs two or more cells thick down their centers. The cells of moss plants contain chlorophyll, the green pigment that is essential for the process of photosynthesis.
Does moss have roots? No, not really. Moss stems end in root-like strands called rhizoids, specialized to hold the moss to its growing surface. Rhizoids anchor moss plants to the surfaces they grow on, but they do not absorb water and nutrients like true plant roots.
Second-Generation GrowthThe second moss structure is really a second generation. Moss reproduction occurs sexually, using separate plants produced at different times. The two separate kinds of moss plants are called gametophytes (which produce gametes) and sporophytes (which produce spores).
Gametophytes are tipped with either inverted cone-shaped areas (archegonia) or male reproductive organs (antheridia). Released sperm (antherizoids) need water since they swim to the archegonium. This is one of the main differences between bryophytes and vascular land plants – mosses need water for their sexual reproduction process.
Fertilization occurs once an antherizoid swims to an archegonium. Sprouting from the gametophyte tip after fertilization, a sporophyte holds itself in place by anchoring a foot in the archegonium.
Spore-Bearing PartsThe sporophyte stalk, called the seta, bears the sporangium (spore capsule) on its tip. One sporangium may produce up to one million spores. Maturing spore capsules are guarded by a covering called the calyptra that shrivels and falls off when the spores are mature. The calyptra can be a distinguishing part of a moss species, and they are often useful in identifying new mosses.
A cap called the operculum tops the capsule's opening under the calyptra. The capsule opening (peristome) can have teeth that help hold it closed. Matured spores are released when the capsule top ruptures and drift off to form new plants. Like the calyptra, the operculum and peristome of some moss species are highly identifiable.
heat moves through the atmosphere through the process of ?
Answer:
Heat moves through the atmosphere through the process of Conduction.
Explanation:
Conduction, radiation and convection all play a role in moving heat between Earth's surface and the atmosphere. Since air is a poor conductor, most energy transfer by conduction occurs right near Earth's surface.
