how does energy get into the air also what happens to the air temperature
Answer:
Since air is a poor conductor, most energy transfer by conduction occurs right near Earth's surface. Conduction directly affects air temperature only a few centimeters into the atmosphere. During the day, sunlight heats the ground, which in turn heats the air directly above it via conduction.

An individual has type ab blood. The father has type a and the mother has type b. What is the individual's phenotype an example of
Answer:
Codominance
Explanation:
Codominance is a type of inheritance pattern in which two alleles of a gene both express themselves in a heterozygous state. Codominance occurs when neither of the two alleles involved are recessive instead both dominate simultaneously.
As described in this question, the father of an individual has type A blood and the mother has type B. However, the individual has type AB blood. This is because alleles for blood types A and B both phenotypically express themselves in the individual. Hence, blood type A and B are said to be codominant and the AB phenotype is showing an example of CODOMINANCE.

Facilitated diffusion requires
A. a protein pump, energy, and a concentration gradient.
B. no energy, net osmotic movement, and a protein pump.
C. a concentration gradient, a protein channel, and no energy.
Answer:
A.Explanation:
TutorialDiffusionDiffusion means that the net movement of particles (molecules) is from an area of high concentration to low concentration.Graph of the simple and facilitated diffusion taking into account the rate of uptake and the concentrationIf the particles can move through the lipid bilayer by simple diffusion, then there is no limit to the number that can fit through the membrane. The rate of diffusion increases linearly as we add more particles to one side of the membrane.If the particles can only pass through protein channels, then the rate of diffusion is determined by the number of channels as well as the number of particles.Once the channels operate at their maximal rate, a further increase in particle numbers no longer increases the apparent rate of diffusion. At this limited rate we describe the protein channel as being saturated.The cartoon illustrates several points about facilitated diffusion. The particles are more concentrated on one side of the membrane, and yet they can move in both directions. However, the net movement is from high particle concentration to low. If the number of particles gets so high on one side of the membrane that they interfere with diffusion through the protein channel, then we observe a limit to the rate of diffusion at the point of saturation.Illustration of facilitated diffusionanimation used with permission of the Virtual Cell Web PageProblem 7 | Answer | Problem 8The Biology Project > Cell Biology > Cell Membranes > Problem SetThe Biology ProjectDepartment of Biochemistry and Molecular BiophysicsUniversity of ArizonaMay 2002Revised: August 2004Contact the Development TeamSimple diffusion does not require energy: facilitated diffusion requires a source of ATP. Simple diffusion can only move material in the direction of a concentration gradient; facilitated diffusion moves materials with and against a concertion gradient.

According to the site, what are the views and approaches for psychodynamic therapy and humanistic therapy?
Answer:
In psychodynamic therapy, therapists help people review emotions, thoughts, early-life experiences, and beliefs to gain insight into their lives and their present-day problems and to evaluate the patterns they have developed over time. Recognizing recurring patterns helps people see the ways in which they avoid distress or develop defense mechanisms as a method of coping so that they can take steps to change those patterns.
Explanation:
Answer: In psychodynamic therapy, therapists work with patients to examine their feelings, thoughts, early experiences, and beliefs in order to acquire understanding of their lives, their current issues, and the patterns that have grown over time. People can take action to change repeating behaviors by being aware of how they avoid distress or establish defense mechanisms by recognizing these tendencies.

One of the pieces of evidence for evolution that Charles Darwin collected on his travels aboard the HMS Beagle was the observation of fossils of extinct animals and similar, but noticeably different species. Giant ground sloth fossils were very similar in shape to the bones of sloths that inhabited the regions of South America he was exploring. The main difference was the size, as the ground sloth fossils were significantly larger that the bones of the sloths he captured alive. What was a conclusion that Darwin was able to arrive to based on this piece of evidence
Answer: Darwin was able to arrive at a conclusion that there was no relationship between the fossils of the ground sloth and the bones of the captured sloths that currently reside in South America.
Explanation:
Evolution is defined as the sum total of adaptive changes that have taken place over a very long period of time. It leads to the development of new species from earlier ones. Evolution is an extremely slow process. It is difficult to obtain direct evidence of evolution in action. However, scientist such as Darwin, have gathered a great deal of indirect evidence that supports the theory of evolution. These evidence comes from many sources including:
--> fossils records
--> biochemical similarities
--> molecular records
--> Comparative anatomy and
--> embryology.
FOSSILS RECORDS shows the existence of species that are now in extinct which lived on Earth during different periods of the planet's history. They provide evidence that organisms from the past are not the same as those found today due to adaptive changes that has occurred over a long period of time on the organism in order to survive in its environment.
There was no relationship between the sloths because of the difference in BONE MASS.

Karyotyping Karyotyping reveals the presence of cancerous genes. examines points of crossing over. can reveal alterations in chromosome number. shows chromosomes as they appear in metaphase of meiosis II.
Answer:
The correct answer is - can reveal alterations in chromosome number.
Explanation:
The karyotype is the process in which images of the chromosomes of an individual are used. These images used for confirmation of the chromosome complement of the individual that include the number of chromosomes and look for abnormal numbers or structures of chromosomes.
Karyotypes are made by standardized staining procedures that give the image of the number and structure of the chromosomes of an individual. It gives an idea of size, shape, number, or any type of alteration in the chromosomes.

Which option describes the question Dave should consider in the following scenario?
Dave's mare has just given birth to a healthy colt, but he is surprised that the colt was born tan when the mother is
black
What color are the colt's eyes?
What nutritional supplements were given?
What other maternal traits were inherited?
What color is the colt's father?
The color of the colt's coat is determined by the genes it inherited from its parents is “What color is the colt's father?”, option D is correct.
Coat color in horses is a complex trait that involves several genes. The most well-known coat colors are black, bay, and chestnut. However, there are many variations and combinations of these colors, such as the tan color observed in this colt.
The color of the eyes is not related to the coat color and is determined by a different set of genes. Nutritional supplements may play a role in the overall health and development of the colt, but they are not likely to affect its coat color. Maternal traits, such as temperament and size, are also inherited, but they are not related to the coat color either, option D is correct.

Have you ever had to estimate something for which there wasn't an exact answer? What was it? What tools did you use to
make your estimation? Discuss.
Answer: Yes, estimation of a population of plant species in a given area. The tool I used was a QUADRAT.
Explanation:
Plants in a small area are easy to count and their distribution is recorded on a map or scale diagram for the area. For larger areas, quadrats are used to obtain a fairly accurate estimate of the number and types of plants in those large areas.
The ESTIMATION of the population of plants can be done using a method called the quadrat sampling method. Here, a QUADRAT which is a rectangular or square frame(tool) made from thick wire, is thrown at random several times. On each landing, the area covered by if is observed. The type of species and their number within the quadrat are recorded. The average number of times each species appears is calculated and the most frequent or dominant species is then determined.
Some quadrats are specially made to mark off an area for the study of seasonal variations of plants. They are sturdier, larger and permanent and can thus serve their purpose through the seasons. These quadrats often have a mapping grid attached so that the flora within it can be mapped at regular intervals.
