Answer: Option B.
Geographic separation.
Explanation:
It is geographic separation that is common to both of them because
Sympatric speciation to occur when certain populations of species isolate reproductively from the the main populations because they can not longer interbreed with each other and they inhabit the same geographical location.
Allopatric speciation occur when two populations of the same species separate from each other geographically which can be as a result of one group of population move to another geographical location.

What might happen to biodiversity in area 1 if the new bird species moved into the area
Answer:
New bird species may alter the ecosystem and modify the trophic chain when they become invasive, leading consequently to the loss of biodiversity
Explanation:
Invasive (also known as alien) species are non-native species capable of spreading into a new area where they have a drastic impact on the ecosystem. An invasive species may cause an important loss of biodiversity and modify the food web in an ecosystem by replacing native species. Examples of invasive bird species include the house sparrow, European starling, cattle egret, rock pigeon, etc. Nonetheless, it is important to highlight that not necessarily new bird species will become invasive (it will depend on their effects on the ecosystem).

The option which correctly lists three scientists who supported the heliocentric model of the solar system is: D. Kepler, Galileo, Copernicus.
A solar system can be defined as a collection of both the inner and outer planets alongside the moon in orbit around the sun. The nine (9) planets of the solar system orbiting around the sun are;
Mercury.Venus.Earth.Mars.Jupiter.Neptune.Venus.Saturn.Pluto.Heliocentric model of the solar system can be defined as a cosmological model that asserts that the Sun lies at or near a central point while the planetary bodies revolve around it.
Basically, the heliocentric model of the solar system was discovered by Nicolaus Copernicus and supported by Johannes Kepler and Galileo Galilei.
In conclusion, the three scientists who supported the heliocentric model of the solar system are Kepler, Galileo, and Copernicus.

Organisms with a narrow range of temperature tolerance would most likely be found where ?
Answer:
there is less fluctuation in abiotic factor such as temperature.
Explanation:
Organisms with a narrow range of temperature tolerance would most likely be found where there is less fluctuation of temperature or variation in temperature because the organisms are tolerant to less variation in abiotic factor such as temperature so if the temperature goes very high or low, then the organism is not able to tolerate and die. So we can say that less variation in temperature are the regions where organisms with a narrow range of temperature tolerance can be found.

Which of the following pairs of hormones are secreted by the posterior pituitary gland?
A) Prolactin and growth hormone
B) Melatonin-stimulating hormone and oxytocin
C) Oxytocin and antidiuretic hormone
D) Follicle-stimulating hormone and thyroid-stimulating hormone
E) Prolactin and ACTH
The pairs of hormones secreted by the posterior pituitary gland are C. Oxytocin and antidiuretic hormone.
What is pituitary gland?The posterior pituitary gland is a small, pea-sized endocrine gland located at the base of the brain. It is connected to the hypothalamus by a stalk. The hypothalamus produces two hormones, oxytocin and antidiuretic hormone (ADH), which are stored in the posterior pituitary gland and released into the bloodstream when needed.
Oxytocin is a hormone that is involved in childbirth, breastfeeding, and social bonding. ADH is a hormone that is involved in regulating water balance and blood pressure.

Where would you expect to find genetic material in a prokaryotic cell?
( WILL MARK BRAINLIEST)
A. In the organelles
B. In the nucleus
C. In the cytoplasm
D. A prokaryotic cell does not genetic material
Answer:
The answer is Option B the nucleus
Explanation:
Genetic information in prokaryotic cells is carried on a single circular piece of DNA which is attached to the cell membrane and in direct contact with the cytoplasm. There is no enclosing membrane, so there is no true nucleus, but simply a concentration of DNA known as a nucleoid.
and DNA is present in the nucleus. Therefore option B is correct

The statement that for each force their is an equal and opposite force refers to which law?
Answer:
The laws of physics.
Explanation:
Formally stated, Newton's third law is: For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object.
Glucose is present in blood plasma at a concentration of approximately 80 mg/dL. A typical 70 kg human has approximately 5 L blood, which is 55% plasma. Using the glucose concentration of Sprite that you calculated in the previous question, how many mL of Sprite does a human need to drink to reach a plasma glucose concentration of 80 mg/dL, assuming none is mobilized?
Answer: 48.93 mL of sprite
Volume of blood in 7 Kg human = 5 L
Percentage of plasma in blood = 55%
Volume of plasma in 5 L blood = (1 L = 10 dL)
Concentration of glucose in plasma = 80 mg/dL
Amount of glucose present in 27.5 dL : 80 mg /dL × 27.5 dL= 2200 mg
Let the volume of sprite with 2200 mg glucose be x
Concentration of glucose in sprite = 44.96 mg/mL

If you buy 3kg of pasta for dinner party how many pounds of pasta are you actually preparing for dinner?
Given :
Mass of pasta buy for dinner party , M = 3 kg .
To Find :
How many pounds of pasta are you actually preparing for dinner .
Solution :
We have to convert 3 kg to pounds .
We know , 1 kg is equal to 2.2 pounds .
So , mass of 3 kg in pounds is :
[tex]M=2.2\times 3\ pounds\\\\M=6.6\ pounds[/tex]
Therefore , 6.6 pounds of pasta is preparing for dinner .
Hence , this is the required solution .

Which options describe the structure of a water molecule? Select all that apply. 1. the molecule has an overall straight shape 2. the hydrogen atoms are attached to the oxygen atom at an angle 3. the molecule has an overall bent shape 4. the hydrogen atoms are attached at opposite ends of the oxygen atom
Answer:3 and 2
Explanation:
For water molecule all options are correct here.
What is the structure of a water molecule ?
Water occupy around 70% of the earth’s surface, it make up about 95% of the living organisms.
Each water molecule is composed up of one molecule of oxygen and two molecules of hydrogen by forming a covalent bond .
A strong bond of attraction between nucleus of the oxygen nucleus and electrons of hydrogen has been seen which form an angle 105° between hydrogen atoms
Due to this asymmetry in shape water has a strong property of strong dipole movement that is highly polarized molecule with both positive and negative charges.
It is very cohesive in nature by developing a strong bonding with itself, and also adhesive in nature.
It shows high boiling point as hydrogen- oxygen bond highly polar and
Hydrogen atoms are present at two corners with a tetrahedron shaped which gives water a high polarity.

Because the cell membrane is made of two layers of lipids it is called a..?
Answer:
The lipid bilayer.
Explanation:
It is a thin polar membrane made of two layers of lipid molecules. These membranes are flat sheets that form a continuous barrier around all cells.
Cell membrane is made of two layers of lipids it is called lipid bilayer.
What is lipid bilayer?The lipid bilayer is a fundamental component of all cell membranes. It is vital for identifying cell boundaries because of the barrier that its structural components offer.
The structure is called a "lipid bilayer" because there are two layers of fat cells arranged in two sheets, and the lipid bilayer, which surrounds all cells and provides the structure of the cell membrane, is usually about five nanometers thick.
The lipid bilayer's structural makeup explains how it acts as a barrier. Lipids are fats that are soluble in oil but not in water. The lipid bilayer's structure is provided by two crucial areas of a lipid.
Therefore, Cell membrane is made of two layers of lipids it is called lipid bilayer.
