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 :)
Answer:
all the above
Explanation:
weathered soil and rock from the ecoregion is eroded and deposited in the upper south Texas plains ecoregion

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.

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.

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
f(t) = 0.515 ≅ 0.52
b. Determine the genotype frequencies of the exposed generation

Which of the following errors would result in a negative result for all samples in an ELISA (including positive controls)? Select all that apply. Failure to add antigen. Failure to add funtional primary antibody. Failure to add functional secondary antibody. Failure to add functional substrate.
Answer:
All errors described will result in a negative result
Explanation:
The enzyme-linked immunosorbent assay (ELISA), is a test used to detect and measure antibodies, antigens and proteins in the blood. An ELISA test uses antibodies and/or antigens that are coupled to an easily-assayed enzyme, thereby this approach combines antibody specificity with the sensitivity of simple enzyme assays. ELISA test involves an antibody or antigen that reacts to form an antigen-antibody complex, where such reaction is interpreted as a positive result. The negative results are evidenced by the lack of reaction, which may be caused by some error during the chain of reactions in the ELISA test: antigen >> primary antibody (reaction) >> functional secondary antibody (reaction) >> conjugated enzyme (reaction) >> functional substrate.
In order for organisms to survive in their environment, an ecosystem must provide the organism with all of the following except
A. edible food.
B. drinkable water.
C. adequate shelter and space.
D. sedimentary rocks.
Answer:

Explanation:
organisms rely on their environment to provide edible food, drinkable water, and adequate shelter and space. sedimentary rocks are no where in the line of must-haves for them to live.
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.

Explanation:
Methods used for permanent contraception in women include laparoscopy, hysteroscopy, and minilaparotomy. These procedures are used to disrupt the fallopian tubes, which carry the egg from the ovaries to the uterus. Or the fallopian tubes may be completely removed.
describe one measure of evolutionary fitness
Reproductive success is someone's production of offspring per breeding event or lifetime. This is not limited by the number of offspring made by one individual, but also the reproductive success of these offspring themselves.
Reproductive success leads to natural selection which can cause microevolution (change in allele frequencies), with fitness-increasing alleles becoming more common in the population.
Fitness is a measure of reproductive success.
What are examples of reproductive success?Example, the offspring produced as a result of normal mating are an example of reproductive success because they too can pass their genetic material on to the next generation.
So, Reproductive success is one measure of evolutionary fitness.
