How does heredity affect a species

Heredity<span>, </span><span>the sum of all biological processes by which particular characteristics are transmitted from parents to their offspring. The concept of heredity encompasses two seemingly paradoxical observations about organisms: the constancy of a </span>species<span> from generation to generation and the </span>variation<span> among individuals within a species. Constancy and variation are actually two sides of the same coin, as becomes clear in the study of </span>genetics<span>. Both aspects of heredity can be explained by </span>genes<span>, the functional units of heritable material that are found within all living </span>cell<span>s. Every member of a species has a set of genes specific to that species. It is this set of genes that provides the constancy of the species. Among individuals within a species, however, variations can occur in the form each </span>genetic<span>s, providing the genetic basis for the fact that no two individuals (except identical twins) have exactly the same traits.</span>

GaryK [48]
Estuaries, often reffered to as the nurseries of the sea provide feedind habitats for many aquatic animals and plants. Fish and shellfish commonly eaten in the U.S such as oyesters and Salmon complete almost half of their lifecycles in estuaries. Due to its shallow water,Pamlico estuary especially provides opportunities such as Fishing, crabbing and watersports as well.
We can be able to determine this concept by basing our facts on two concepts. Nutrient Influx, upon reaching the estuarian ecosystem, the nutrients in the presence of sunlight undergoes photosynthesis and produce phytoplanktons. Basically, where there is sunlight, we can assume there is a nutrient influx. Presence of Phytoplanktons will in turn help attract animals such as fish. Also, another contribution of nutrient influx is manure produced by the animals

Sewage treatment plans and fertilizer runoff. Auto emissions of nitrogen, fertilizers applied on golf courses and home gardens can contribute. Some plankton species may produce toxins that might cause these outbreaks

icang [17]
1. breeding of individuals that have genes for two different characteristics:
DIHYBRID CROSS.
We call it a dihybrid cross when we are considering a cross between two different traits.
"di" means having two traits involved (for example, trait A and trait B), the "hybrid" means that each trait will have two different alleles (for gene A: A or a; for gene B: B or b), one is dominant and the other is recessive.

2. a grid system used to predict possible combinations of genes due to random fertilization: PUNNETT SQUARE
The Punnett square is a grid system that helps us predict an outcome of a cross or a breeding experiment. We this, we can determine the probability of an offspring having a particular genotype.
This is very useful when we are considering more than one gene,  making it less confusing.

3. a condition in which both alleles are dominant: CODOMINANCE
Tere are alleles that have the capacity of dominating at the same time, and when an organism is heterozygotic, both alleles are expressed.
For example, a white chicken(WW) crossed with a black chicken (BB):  100% of the offspring being WB. With this genotype, they have black feathers and white feathers. It's not a blend of colors, but a case where both are expressing.

4. when more than two alternatives exist for a gene: MULTIPLE ALLELES
Mendel thought that only two possible alternatives could exist for a gene, but there are cases that have more than 3 possibilities. Some of those can be really popular in a population while others not so much.
This happens with rabbit's fur. They can be black, brown, grayish,
Himalayan patterning or white fur.

 5.a condition in which neither pair of alleles is dominant or recessive, so the traits blend in the phenotype: INCOMPLETE DOMINANCE
Some alleles are not completely dominant, and when that's the case the phenotype of a heterozygous organism will be a mix between the phenotypes of its homozygous parents.
For example:
plant 1: RR -red
plant 2: rr-white
By crossing this plants we will obtain 100%  of the offspring with a color mix: pink.(genotype: Rr)
Red and white are not completely dominating so it results in a blend of colors.

Which respiratory-associated muscles would contract or relax during forced expiration, for example blowing up a balloon?
Nutka1998 [239]
The correct answer is B, internal intercostal muscles and abdominal muscles would contract.
Exhalation is the flow of the breath out of the body. During forced exhalation, internal intercostal muscles contracts which lower the rib cage and decrease thoracic volume, while the abdominal muscles push up on the diaphragm which causes the thoracic cavity to contract.

What is postharvest handling?​
ohaa [14]

Explanation:

In agriculture, postharvest handling is the stage of crop production immediately following harvest, including cooling, cleaning, sorting and packing. The instant a crop is removed from the ground, or separated from its parent plant, it begins to deteriorate.
