What are air masses, and how do they work? Don't copy and paste.

Answers

What are Air Masses:  They large volumes of air that have generally the same temperature and pressure.

How they work: One is heated by an electrical current, the other is not. As air flows across the heated wire, it cools down.

Example of an Air Mass: The air masses in and around North America include the continental arctic, maritime polar, maritime tropical, continental tropical, and continental polar air masses. Air is not the same everywhere.

Fact: Unstable air masses have different temperatures and pressures.

How they are formed: An air mass forms whenever the atmosphere remains in contact with a large, relatively uniform land or sea surface for a time sufficiently long to acquire the temperature and moisture properties of that surface.

*** The Earth's major air masses originate in polar or subtropical latitudes.

All of an organism's characteristics are inheritable which evolves over millions of years. An example of this is the modern day horse's foot.

What is Evolution?

This is referred to as the change in the heritable characteristics of biological populations over successive generations.

All an organism's characteristics can be inherited and evolves over a period of time as a result of the changing environmental conditions which helps them to adjust thereby increasing their chances of survival hence preventing extinction of species.

For example, over millions of years of evolution, many horses lost their side toes and developed a single hoof as a result of them needing to move at faster speeds to evade predators.

If a scientist wanted to follow Mendel’s experiment with a different kind of plant, which type of plant would she examine?

Answers

Answer: Pure line plant

Explanation:

Pure line plants are those plants that are used for breeding and selecting organisms with a desire trait to a number of generations until the wanted trait is established. Mendel had chosen pea plant for his experiments and that was a pure line species. It was bred to many generations so as to obtain the desired trait in successive generation. The plants were utilized to study the laws of inheritance. Also it was noticed that one trait being recessive in one generation will be expressive in other generation.

Does every gene combination show up in the offspring?

Answers

Answer:

Answer!

Explanation:

Okay so, genes come in different varieties; which are called allele. somatic cells contain two alleles for every gene, with one allele provided by each parent of an organism. BUT, an allele that is hidden, or not expressed by an organism, can still be passed on to that organism's offspring and expressed in a later generation.

During meiosis I, chromosomal pairs randomly align along the metaphase plate. Each chromosome pair member carries one allele for each gene. Every gene combination shows up in the offspring.

Chance determines which of the 23 homologous pairs of both parents' chromosomes are inherited. The possible combinations of 23 chromosomal pairs total 8,324,608. As a result, the chromosomal combinations of two gametes are almost never identical.

Actually, each parent has two distinct gene pools. Additionally, only half of each parent's DNA is passed on to their offspring. and that the randomness of the portion that is passed down. All of these factors work together to guarantee that every child has a distinct collection of genes.

Compare the punnet squares you constructed in Activity 4, "Breeding Corn", with the punnet squares you constructed in this activity. By answering the following questions, show how the possible outcomes of a cross for one trait help analyze two traits.

A. How did you need to change the punnet square to consider two traits?

B. How would you need to change the punnet square if you were to consider three traits?

Answers

Punnett squares represent the possible genotypes of the offspring according to the parental's gamete combinations. The number of gametes depend on the number of alleles and traits considered.  A) New rows and columns were added to the square because each parent contributed with four types of gametes (4 rows and 4 columns). B) The square would be constructed with eight rows and eight columns.

What is a Punnett square?

The Punnett square is a graphic representation that shows the different types of gamete combinations according to the alleles involved in a cross.

Punnett squares are composed of columns and rows in which all the different potential gametes are placed.

columns represent one of the parental gametes, and rows represent the other parental's gametes.

The intersection between each column and row suggests a possible genotype among the offspring.

The number of columns and rows will depend on the number of genes involved in the cross. We can use the formula 2ⁿ to figure out how many gametes are possible (2 is the number of alleles, and n is the number of genes). Assuming diallelic genes,

If we consider only one gene, two types of gametes are possible (2¹). If we consider two genes, four types of gametes are possible (2²). If we consider three genes, eight types of gametes are possible (2³)

Punnett squares shows the probabilities of getting offspring with different genotypes and their consequent phenotypes.

In the exposed example, we need to compare a punnett square in which we consider only one gene with a punnett square in wich two genes are considered.

From activity 4: Punnett square

Cross: Purple with yellow

Parentals) PP   x   pp

Gametes)   P   P    p    p

Punnett square)

                          P     P

                P      p

          P   PP   Pp

          p   Pp   pp

F2) 75% Purple (PP + Pp) and 1/4 yellow kernels (pp)

In these crosses, we only consider one diallelic gene that expresses complete dominance.

Punnett squares are composed of two columns and two rows in which both types of gametes are located.

Now, we need to consider two genes (P and S), which means four alleles are involved and four type of gametes are possible.

Cross: Between two dihybrid individuals

Parentals)        PpSs         x           PpSs

Gametes) PS, Ps, pS, ps        PS, Ps, pS, ps

               pS     PpSS     PpSs      ppSS      ppSs

               ps     PpSs      Ppss       ppSs      ppss

F1)

9/16 individuals are expected to express both dominant traits (PPSS, PpSS, PPSs, PpSs)3/16 individuals are expected to express only one dominant trait (PPss, Ppss)3/16 individuals are expected to express the other dominant trait (ppSS, ppSs)        1/16 individuals are expected to express both recessive traits (ppss)  

Now, we need to compare Punnett squares from activity 4 (one trait) with this new Punnett square (two traits), and answer the questions,

A. How did you need to change the punnet square to consider two traits?

Since we consider two traits, we need to add rows and columns according to the possible gametes. The new punnett square must have four columns and four rows (2ⁿ = 2² = 4).

Remember that all the possible gametes depend on the number of possible allelic combinations.

B. How would you need to change the punnet square if you were to consider three traits?

If we consider three traits, we need to construct a Punnett square with eight columns and eight rows (2ⁿ = 2³ = 8).

Answers

Answer:

1. A forest of pine trees is burned over a 10 mile area when lightning strikes a tree. In the spring, a few seedlings are beginning to sprout → secondary succession.

2. A glacier has scraped all soil from a rocky area. As it slowly retreats, some of the rock is broken down by weathering. Some moss begins to grow → primary succession.

3. A small symbiotic organism secretes acid into the rock to anchor itself in place → lichens - pioneer organisms.

Explanation:

The succession is the colonization of an open area and includes all the changes the area suffers since then. It is a sequence of events that involves the establishment of different species through time. A sequence of changes that occur in a community temporally and spatially. Local colonizations and extinctions occur while ecosystems evolve at a more complex level.

Ecological succession occurs in stages. The first stages are represented by communities of simple trophic levels and few species. With time, the communities go through different stages.  They transform into more complex ecosystems that are much richer in diversity, showing more interaction among the different species that compose it. The final stage is known as the climax and represents a mature and stable system.

While the community is going through these changes, many species get extinct while many others get to emerge and survive. It occurs overlapping of different taxonomic groups that interact with each other competing or beneficiating other groups.

There are two types of succession, primary and secondary, depending on the magnitude of the alteration.

Primary succession refers to an open space with no living organisms, such as a bare rock exposed due to a retreating glacier, a volcanic activity, or an intense fire. If previous species were inhabiting this area, after the event, nothing is left.  

In those cases where there is an alteration or disturbance at a site that opens the area, it allows new species to grow. With time, new species arrive and manage to establish again. The order of the establishment depends on the strategies of each of the species to survive.  

First, pioneer species arrive. These are the first inhabitants, mostly lichens or plants with the capability of surviving in such an environment. Only a few pioneers can establish in the open space. Pioneers modify the habitat, making it more suitable for the establishment of later species, converting rock into fertile soil. As conditions get better, new species arrive like grasses. Grasses and pioneers keep modifying the soil,  making it better with time. New species arrive. Habitat modification keeps on going while new species establish. They produce shadows, alter the temperature, and humidity, fertilizing the soil, competing for resources. Competition becomes more frequent between species. The first species are eventually eliminated by competition, but new species keep appearing and competing for resources. This sequence continues until the commuting reaches a climax, becoming stable and lasting for hundreds of years until another disturbance occurs.

Secondary succession refers to an open space left after a perturbation that might have removed all or some of the vegetable forms of life that used to inhabits that area. But the soil remains good and fertile. It has spores and seeds that will emerge when the conditions are appropriate. The disturbance occurred but vegetable species have strategies to survive the event and grow once it´s over. Pine trees are adapted to fire, and some species need fire to germinate.
