What is an example of weathering, erosion, and deposition in Texas? (A)Gradual change to Guadalupe Peak (B)All of the above (C)The changing coastline of Texas (D)The creation of Palo Duro Canyon
Answer: Weathering, erosion, and deposition from the terrestrial surface topography and soil characteristics. These processes, for example, have formed a variety of landforms in Texas like beaches, plateaus, mountains, and canyons as well as soil types like fertile soil, clay-rich soil, and sandy soil. The combination of topography, soil, and climatic conditions in an area defines the types of habitats that the area can support this is crucial to ecoregion classification. Ten separate ecoregions occur in Texas including 1) East Texas Pineywoods, 2) Gulf Coast Prairies and Marshes, 3) Oak Woods and Prairies, 4) Blackland Prairie, 5) cross timbers and prairies (6) Rolling Plains, (7) High Plains, (8) TransPecos, (9) South Texas Plains, (Brush Country), and (10) Edwards Plateau. Such ecoregions are named for the major types of habitats topographical features (e.g. Edwards Plateau) present in their areas. The weathering, erosion, and deposition of each of these ecoregions have an important influence. Hope This Helps :)

3. In centaurs, the allele for curly tails (T) is incompletely dominant to the allele for straight tails (t). The hybrid genotype results in wavy tails. In a population of 1500 centaurs, 315 have curly tails, 820 have wavy tails, and the remainder has straight tails.
a. Determine the allele frequencies of: T = ____________ t = ____________
b. Determine the genotype frequencies of TT = ___________ tt = ____________
Answer:
a. Determine the allele frequencies of:
f(T) = 0.485 ≅ 0.48

On the planet Greenport, individuals display two distinct phenotypes: their favorite color s blue versus their favorite color is green. Every Greenportian has one of these two phenotypes. Suppose the phenotypes are determined by genotypes on two loci. The first locus, Quogue, has alleles F and f. The second locus, Massapequa, has alleles G and g. These loci act in an epistatic manner to produce the favorite-color phenotypes. A cross between two doubly heterozygous individuals, that is, each with the two-locus genotype FfGg, produces 1100 offspring whose favorite color is blue, and 875 offspring whose favorite color is green. What form of epistasis is most consistent with these counts
Answer:
double recessive epistasis.

Answer:
Most of the water on earth is located in the oceans
Explanation:
The question states, 97 percent of the worlds water is salt water, which is what oceans are made up of, and, obviously, oceans are made up of salt water, and oceans also cover up approximately 71 percent of the earth, which from there, we can infer, that most of Earths' water is in the oceans.

.Explicati de ce algele pluricelulare au culoarea rosie,verde respectiv bruna ?
Answer:
Due to different pigments.
Explanation:
The multicellular algae are red, green and brown because of the presence of pigments. The red algae are red in colour because of the presence of the phycoerythrin which is a type of pigment. This pigment reflects red light due to already presence in its body and absorbs blue light that is necessary for photosynthesis process. The brown algae contain fucoxanthin pigment and green algae contain xanthophylls pigments that are responsible for its colour so we can conclude that these different types of pigments are responsible for the different colour of algae.

Explanation:
Select ALL of the following genotypes below that respresent males.
XXY
XX
XYY
XXX
XY
Answer:
Is it XXX that all males want?
Explanation:
Just joking! I still think it is XXY
The genotype that represents males is XY of 50 % of both X and Y chromosomes where a slight change in the alignment might cause to chromosomal disorders .
XXY , XYY , XY represents males genotypes.
What are chromosomal disorders ?
These are the disorders which are associated with the change in the normal XY sequence of males. Various disorders and syndromes are associated with the mutation and the responsible factor can be trisomy like.
XXY is a chromosomal mutation found in the males only called as Jacob syndrome, XYY is a chromosomal disorder called as klinefelter syndrome found in males only.
XX is the genotype of a female, XXX is a condition that affects 1 in every 1000 females.
Thus, except XX and XXX is the exception as both of these represent females.

A 15 mL sample of gasoline has a mass of 11 g. What is the density of the gasoline?
The density of gasoline with a mass of 11g and volume of 15mL is 0.733g/mL.
DENSITY:The density of a substance can be calculated by dividing the mass of the substance by its volume. That is;Density = mass ÷ volume
According to this question, a 15 mL sample of gasoline has a mass of 11 g. The density of gasoline is calculated as follows:Density = 11g ÷ 15mL
Density = 0.733g/mL
Therefore, the density of gasoline with a mass of 11g and volume of 15mL is 0.733g/mL.

3. Describe a scenario where
identifying an individual through
the use of DNA fingerprinting
would be important.
DNA fingerprinting would be helpful in a crime scene with blood because it was indicate whether the person was a victim or a victim's relative.
What is DNA fingerprinting?Paternity testing and other forensic applications as well as criminal investigations all make use of DNA fingerprinting.
In these cases, the goal is to "match" two DNA fingerprints, such as a DNA sample from a known person and one from an unknown person, with one another.
A chemical test called DNA fingerprinting can reveal a person's or another living thing's genetic makeup. It is used as testimony in court, to identify corpses, find blood relatives, and search for medical treatments.
Therefore, at a crime scene, it will be helpful to do DNA fingerprinting with any sample including blood, and hair.

Answer:
1. Archipelago in Ecuador
2. Different beaks
3. He used Darwinism/ survival of the fittest / evolution to explain these adaptations. The birds on different islands adapted to varying, but specific food types.
4. mutation, gene flow, genetic drift, and natural selection.
Mutation creates new genetic variation in a gene pool.
Gene flow and genetic drift alter allele frequencies in a gene pool.
5. The finches have few predators / competition for food.
Explanation:
1. Galapagos Islands located in archipelago in Ecuador near the west side of pacific ocean.
2. Different beaks variations did Charles Darwin observe after studying the Galapagos finches.
What are Galapagos Islands known for?The Galápagos are best known for their diverse of plant and animal species. Many species are endemic, that means they are not found anywhere else in the world.
3. Darwin used theory as he gave that survival of the fittest and other will die and evolution to explain these adaptations. The birds on different islands adapted to varying, but specific food types.
4. Darwin’s on the origin of Species, four factors affect evolution are
mutation: a mutation is a change in the DNA sequence of an organism. gene flow: is the introduction of genetic material from one population of a species to another, that leads to change in the composition of the gene pool of the receiving population.genetic drift: is a mechanism of evolution featured by random fluctuations in the frequency of a specific version of a gene (allele) in a population.natural selection: is the process by which populations of living organisms adapt and change.5. Daphne Major was the ideal place to study the evolution of the finches because the finches have few predators / competition for food on that island.
6. The four factors that affect evolution are mutations, natural selection, genetic drift and the gene flow, In the case, if the ground finches which Grants studied, we can observe the working of the natural selection.
