A male horse with a white coat is mated with a female horse with a brown coat. If coat color is a codominant trait, what would you expect the offspring to have?
All white coats
All brown coats
Mixed white and brown coats
Mixed coats of the recessive colors
Answers
Codominance is a condition observed in the inheritance of coat color in the horse. The offspring of the cross between white coat male horse and brown coat female horse is mixed white and brown cats. Thus, the correct option is C.
What is Codominance?
Codominance is a non-mendelian inheritance. It is an exception of Mendelian inheritance. It is a heterozygous condition in which both the alleles present at a gene locus are fully expressed in the phenotype of an organism. Alleles which show an independent effect are called as Codominant alleles whereas in Mendelian inheritance, one allele is dominant over the other allele which is recessive. In codominance, neither phenotype is completely dominant over other.
In the cross between a male horse with white coat and a female horse with brown coat, the coat color of the offspring produced will be a mixture of white and brown coat color.
Therefore, the correct option is C.

if a parent cell starts with 22 chromosomes how many chromosomes will each daughter cell have after mitosis

Answer:
For mitosis, the DNA content of the daughter cells and the mother cell will always be identical. Since the number of cells have doubled, so has the DNA. The 16 chromosomes in the mother cell will be duplicated, then the duplicates split and evenly divided into the daughter cells. The 16 chromosomes in each daughter cell will be non-duplicated at first.

Increased keystone species
Reduced species richness
Increased invasive species
Increased foundation species
Answers
Answer:
Increased keystone species
Explanation:
An organism is a keystone species when it contributes to the definition of a given ecosystem such that the absence of the keystone species in an ecosystem, the ecosystem will change dramatically or be gradually wiped out
The effect of the keystone on its environment is unevenly large when compared to its abundance relative among other organisms within the ecosystem
The keystone is therefore, a prime source of balance of nature, diversity and well-being of the ecosystem
Therefore, the option that contributes to the diversity of the ecosystem is;
Increased keystone species.

ecosystem contain both blank and blank parts
Answers
Explanation:
Ecosystems contain biotic or living, parts, as well as abiotic factors, or nonliving parts.
Every ecosystem contains both biotic and abiotic components, such as the biotic component, which contains the living forms such as the animal and the plant, and the non-living components, which are called the abiotic component.
What role does the ecosystem play on Earth?There are numerous ecosystems on Earth, each with its own set of functions and living forms, but these are essential for human survival as they support a wide variety of plant and animal species, thus maintaining the biodiversity of the earth. By absorbing and storing carbon, forests, oceans, and wetlands help to regulate the earth's climate by managing the carbon cycle and regulating the climate.
Hence, every ecosystem contains both biotic and abiotic components, such as the biotic component, which contains the living forms such as the animal and the plant, and the non-living components, which are called the abiotic component.

1. Which weather station model above would most likely have snow? ___________
2. Which weather station model above would most likely have rain? ____________
3. Which weather station above has the highest air pressure? ____________
4. Which weather station model above has the highest wind speed?_________
Answers
Answer:
1. Station B
Station B has one of the lowest temperatures of 32°F(top left) which is a temperature that snow can form at. It also has full cloud cover which is something that station C does not have and as clouds are needed for snow, station B is most likely to have snow.
2. Station A
Station A has the highest dew point at 75 (bottom left) which means that it has the highest humidity and so is the most likely to have rain. That along with a full cloud cover (shaded circle), means there are clouds for rain to fall from.
3. Station B
Has the highest pressure at 998.
4. Station C
Wind speed is measured by the lines protruding from the circle and for this simplistic model, the more lines it has, the faster the wind is going. Station C therefore has the fastest wind speed.
An important difference between a series and a parallel circuit is that a series circuit cannot have any breaks. A parallel circuit can have a break in one branch and the current can still flow through another branch.
Answers
Answer:
Yes.
Explanation:
Parallel circuit are those types of circuits in which break in one branch does not prevent the flow of current in the circuit and the current can still flow through another branch because there are more ways through which the current moves to other sources while on the other hand, series circuit refers to those circuits in which break in one branch can prevent the current flow in the circuit and the other sources can't receive current due to broken of the connection.

a sodium atom that has lost an electron comes near a chlorine atom that has gained an electron
Answers
Answer:
When a sodium atom that has lost an electron comes near a chlorine atom that has gained an electron, an ionic bond is formed.
Explanation:
The bonds which are produced between a metal ion and a non-metal ion are termed as ionic bonds. Sodium is metal while chlorine is a non-metallic element, ionic bonds are formed in between them.
Sodium has one electron in its outer most shell whereas a chlorine atom has seven electrons in its outermost shell. To become stable, sodium donates its electron to the chlorine atom and hence ionic bond is formed between them.
