how does geographic isolation cause an increase in differences between two groups
Answer:
What was once a continuous population is divided into two or more smaller populations. This can occur when rivers change course, mountains rise, continents drift, or organisms migrate. The geographic barrier isn't necessarily a physical barrier that separates two or more groups of organisms. It might just be unfavorable habitat between the two populations that keeps them from mating with one another.

What term describes parts of the body that are made from different kinds of cell
Answer:
The term that describes the parts of the body with different kindsof cells is organs, which in turn are made up of different tissues.
Explanation:
The cell is the structural and functional unit of all living beings, with the capacity to multiply and unite to form tissues.
Each tissue is a differentiated or specialized structure, formed by groups of cells of the same type, such as muscle, nerve, connective, cartilage and bone tissue, among others.
The specialized tissues in turn form organs, with specific structures and functions, such as muscle, brain and nerves or bones and joints. For this reason, organs are different body parts, formed by different kinds of cells.
1. Consider the statement: "Sickle cell disease is a(n)
disease."
Which of the following terms could fill in the blank to make the statement true? Write "yes" or "no" next to each
possible response. There may be more than one correct answer.
Genetic
Infectious
Potentially lethal
Inherited
Answer:
Genetic = yes
Infectious = no
Potentially lethal = yes
Inherited = yes
Explanation:
"Sickle Cell Disease" is a blood disorder that is mostly inherited. An example of this is the "Sickle Cell Anemia," which means the body of the person is lacking in red blood cells. In order for an infant to carry such disease, both of his parents must pass the defective gene to him. It is a potentially lethal or deadly disease because if not given remedy, it may lead to several complications such as organ damage, leg ulcers, blindness, etc.
It is not infectious, which means that a person with a Sickle Cell Disease cannot transfer it to another person. It is not likely to spread as well.

What do plants produce when they make their own food?
Answer:
Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel. These primary producers form the base of an ecosystem and fuel the next trophic levels.
Explanation:
Answer:
Their roots take up water and minerals from the ground and their leaves absorb a gas called carbon dioxide (CO2) from the air. They convert these ingredients into food by using energy from sunlight. This process is called photosynthesis, which means ‘making out of light’. The foods are called glucose and starch
2. What are genes, and how are they related to alleles and chromosomes? Start with the definitions of genes and alleles. (2 points)
Answer:
Genes are portions of DNA that contains information to encode proteins
Alleles are different forms of one gene
Chromosomes are closed circular DNA molecules that contain the genetic material of an organism
Explanation:
Genes can be defined as regions of DNA which are transcribed to produce messenger RNAs (mRNAs) by a process known as transcription. Subsequently, these mRNAs are translated into proteins. In diploid organisms, each gene contains two different forms called alleles. A chromosome is a long DNA molecule that contains part or even the entire genetic material of an organism. In diploid organisms, one chromosome contains one allele (inherited from one parent), while its homologous chromosome pair contains another allele of the same gene (inherited from the other parent).
Identify whether each item is a reactant or a product of cellular respiration
Answer:
Glucose is a reactant of cellular respiration.
Carbon dioxide and water are both products if cellular respiration.
Note: The question is incomplete. The complete question is given below:
Identify whether each item is a reactant or a product of cellular respiration. glucose carbon dioxide (co2) water (h2o)
Explanation:
Cellular respiration is the process by which glucose is broken down by the cells to produce the energy molecules, ATP.
The various reaction steps of cellular respiration include glycolysis- where glucose is broken down into two molecules of pyruvate, the citric acid cycle- where two acetylCoA molecules produced from the oxidation of pyruvate are converted to carbon dioxide molecules, and finally the electron transport chain- where the electron-donors NADH and FADH2 produced in the citric acid cycle donate their electrons to oxygen to produce water molecules.
The overall chemical reaction for cellular respiration is represented as follows:
C6H12O6 + 6O2 → 6CO2 + 6H2O
1 molecule of glucose reacts with six molecules of oxygen to produce six molecules of carbon dioxide and six molecules of water.
Therefore, glucose is a reactant while carbon dioxide and water are both products of cellular respiration.

The principles used to collect, process and analyze statistical data in Agriculture is explained below in details.
Explanation:
There are multiple techniques used to collect or receive data for statistical examination. Three of the most traditional techniques are Direct Observation • Operations and • Surveys. A review petitions data from people; e.g. Gallup surveys; pre-election surveys; marketing reviews. Field data collection facilitates us to gather important information such as the crops farmed, agronomic methods utilized by the farmer, and data on the temporary growth of crops.
What is an event of a convention current in the air
Answer:
Convection drives the circulation of air in the earth’s atmosphere. The sun heats the air near the earth’s equator, which becomes less dense and rises upward. As it rises, it cools and becomes less dense than the air around it, spreading out and descending toward the equator again.
Explanation:
What characteristic of water causes water to stick to the side of a test tube?
I need a claim, evidence, and reasoning !
Answer:
The characteristic of water that makes this liquid stick to the side of a test tube is called capillarity (Claim).
Explanation:
Water (H₂O) is a polar molecule with the ability to generate van der Waals forces, which is explained by the 4 hydrogen bonds it forms to bind to other substances. The consequence of the forces of the molecular bonds are four properties of H₂O, including surface tension, cohesion, adhesion and capillarity.
- Claim: The characteristic of water that makes this liquid stick to the side of a test tube is called capillarity.
- Evidence: Cohesion and adhesion of water are properties that come from the forces of the molecular bonds of water, and whose effect is the ability of water to wet surfaces and adhere to a tube that contains it, the latter due to capillarity. Capillarity also allows water to rise through the roots and stems of plants, through their thin vascular ducts.
- Reasoning: cohesion in water depends on the force of attraction between H₂O molecules, adhesion is the capacity of H₂O molecules to join other different molecules and —together with surface tension— make H₂O molecules close to the walls of a glass tube adhere to it, which represents capillarity.
The effect of capillarity is more evident when the test tube is of a smaller diameter, although capillarity and adhesion to its walls always exist, and to a greater degree than any other substance.

A population of Muscovy ducks contains 13 birds with black masks and 37 birds with red masks. Red masks are the dominant trait. What is the frequency of the black allele? What is the frequency of the red allele? What is the frequency of heterozygotes?
Answer: Black allele has frequency of 0.14.
Red allele has frequency of 0.86.
The frequency of heterozygotes is 0.241
Explanation: Hardy-Weinberg model states the frequency of alleles in a population will stay in equilibrium as long as there are external influences. It is also used to determine alleles frequencies using the following equations:
[tex]p+q=1[/tex]
[tex]p^{2}+2pq+q^{2}=1[/tex]
p represents frequency of dominant allele;
q represents frequency of recessive allele;
2pq is frequency of heterozygotes;
For the frequency of red allele, which is dominant, we can use:
[tex]p^{2}=\frac{37}{13+37}[/tex]
[tex]p^{2}=\frac{37}{50}[/tex]
[tex]p^{2}=0.74[/tex]
[tex]p=\sqrt{0.74}[/tex]
p = 0.86
For the black allele:
[tex]p+q=1[/tex]
[tex]q=1-p[/tex]
[tex]q=1-0.86[/tex]
q = 0.14
Frequency of heterozygotes is
2pq = 2(0.86)(0.14)
2pq = 0.241
Frequencies for a population of Muscovy ducks are 0.86 for red allele, 0.14 for black allele and 0.241 for heterozygote.
