Answer:
D. A duck flies to another pond.
The above sentence is an example of emigration. Emigration refers to moving from one area to another for a long or permanent period. In this instance, a duck is leaving the pond it originally resided in (along a population other ducks) in order to reside in another pond. Therefore, it can be said that the duck "emigrated".

What is the morula? And when does it develop?
Answer:
Morula: a solid ball of cells resulting from division of a fertilized ovum, and from which a blastula is formed.
When is it formed: In humans, the blastocyst is formed approximately five days after fertilization. This stage is preceded by the morula. The morula is a solid ball of about 16 undifferentiated, spherical cells.
tbh i don't really know when it's formed, but i looked it up and that's what it gave me. i hope it helped :)
What are the similarities and differences between the two karyotypes?
Answer:
The typical human karyotypes contain 22 pairs of autosomal chromosomes and one pair of sex chromosomes (allosomes). The most common karyotypes for females contain two X chromosomes and are denoted 46,XX; males usually have both an X and a Y chromosome denoted 46,XY.

What is a fixed allele?
O A. An allele that mutates with each generation
B. An allele that is found on many genes
C. An allele present in all members of a population
ОО
D. An allele that formed by adaptive radiation
Answer:
C. An allele present in all members of a population
Explanation:
Just took the quiz
A fixed allele is an allele that is present in all members of a population and has a frequency of 100%. Therefore, option (C) is correct.
What is an allele?An allele is a variant form of a gene that arises through mutation and is located on a specific location on a chromosome, known as a locus. Genes code for specific traits or characteristics, such as eye color or blood type, and alleles determine the variations of these traits.
For example, the gene that determines eye color has several different alleles, including blue, green, and brown, which produce different variations of the trait.
Alleles can be dominant, meaning that they are always expressed in the phenotype of an organism, or recessive, meaning that they are only expressed when paired with another recessive allele. The combination of alleles that an individual inherits from their parents determines their unique genotype and phenotype.

how would you determine the hardness of a mineral
Mohs Hardness Scale
Explanation:
A mineral's hardness is a measure of its relative resistance to scratching, measured by scratching the mineral against another substance of known hardness on the Mohs Hardness Scale.
A root cell may continue to absorb minerals even though the concentration of the minerals is greater inside the cell than in the soil. This absorption is accomplished mainly by —.
Answer:
Root hair cells
Explanation:
If the external environment of a living cell has a greater concentration of salt than the cytoplasm within the cell, the cell will tend to.

All of the following describe outcomes of urbanization except
O decreased soil pollution
O food chain disruption in a natural habitat
O increased wastewater from sewage drainage
O loss of plant biodiversity
Answer:
O decreased soil pollution
Explanation:
Urbanization does not lead to decreased soil pollution.
Pollution is the introduction of contaminants into the environments. As urbanization progresses and the population of people in a place increases, soil pollution increases.
Also, industrial expansion causes increased production of wastes. So, some of these wastes find their way into the environment of which the soil is a main component. There is an increased amount of soil pollution.a) Which country looks like it is experiencing exponential growth?
b) Which country looks like it has reached its carrying capacity?
c) Because it has reached its carrying capacity, describe the relationship between
its birth rates and death rates.
d) Describe what is happening to Europe's population size in terms of birth rates
and death rates.
e) Which country or countries could be experiencing:
emigration:
Explain your answer.
.
-immigration:
Explain your answer.
India has a sharp rising trend and a quickly growing population, so it appears to be growing exponentially. It seems that Japan's carrying capacity has been achieved.
How do population growth and carrying capacity relate to one another?Growing populations may be impacted by increased density in a given area. The greatest number of a species that an ecosystem can sustain is referred to as the carrying capacity of a region. Carrying capacity is based on the amount of resources available (food, habitat, water).
What are some examples of exponential population growth?The term for this quick trend of population rise is exponential expansion. The best illustration of exponential development is found in bacteria. Via prokaryotic fission, prokaryotes, such as bacteria, divide.

The diagram shown represents a cell that will undergo mitosis. Which diagrams below best illustrate the nuclei of the daughter cells that result from a normal mitotic cell division of the parent cell shown?
Diagram A best illustrates the nuclei of the daughter cells that result from a normal mitotic cell division.
Mitosis is a type of cell division by which a parental cell divides to produce two genetically identical daughter cells.In this case, the parental cell has three homo-logous pairs of chromosomes, thereby both daughter cells will also have three pairs of homo-logous chromosomes-Somatic (body) cells reproduce by mitosis, while germinal cells reproduce by meiosis.In conclusion, diagram A best illustrates the nuclei of the daughter cells that result from a normal mitotic cell division.

Which of the following statements describes the structure of the plasma membrane?
a It is a lipid bilayer with the hydrophobic area pointing inward, and the hydrophilic area facing outward.
b Protein molecules make up the membrane, which makes it a strong structure.
c The plasma membrane is made mainly from carbohydrates that give the cell energy.
d It is made primarily of cholesterol that allows the cells to communicate with others.
Answer:
A. It is a lipid bilayer with the hydrophobic area pointing inward, and the hydrophilic area facing outward.
Explanation:
The plasma membrane (also known as the cell membrane) is a membrane that separates the cell's interior from the environment that surrounds it, protecting it. It consists of lipids, proteins, and carbohydrates.
Its main component are phospholipids that create a bilayer. Phospholipids consist of two hydrophobic tails and a hydrophilic head and are arranged so that the tails face inward and the heads outwards.
This is why option A is the correct one.

true false
Answer:
True
Explanation:
Temperature is another condition that affects the speed of sound. Heat, like sound, is a form of kinetic energy. Molecules at higher temperatures have more energy and can vibrate faster and allow sound waves to travel more quickly.
Therefore, sound travels faster at higher temperatures and slower at lower temperatures.
