Answer:
B. Energy is transferred from the cooler air to the warmer ground.
Explanation:
When cooler air particles come into contact with the warmer ground, energy is transferred from the cooler
air to the warmer ground.
Answer: The temperature of air would decrease.
Explanation:
The energy gets transferred from hot object to cold object until the two objects are in thermal equilibrium. When air transfers energy to a cooler object, it means the air it self is cooling down till the air and the object are in thermal equilibrium. Thus, the temperature of air would decrease.

Mutations and variation occur randomly. True\ False
Answer:
true
Explanation:
The gene for nose shape is found on the X chromosome. Round nose is dominant to pointed nose. Human individuals with XXY (an additional X chromosome) are designated male. Individuals with XO (only one X chromosome) are designated female. Identify the possible nondisjunction events (rare mistakes during meiosis) that could explain the phenotype of the offspring. An XY parent with a round nose and a XX parent with a round nose have an offspring with Klinefelter Syndrome (genotype XXY) with a pointed nose.
Answer:
Explanation:
in this case female parent XX is hetrozygous for round nose. when a cross between round nose father XY and hetrozygous round nose mother takes place and suddenly a chromosomal nondisjuction occurs, the chromosomes carrying genes for pointed tip nose come togather in a gamete and a gamete (egg) with XX chromosomes is appeared having 24 chromosomes instead of 23. when this gamete fertilizes with a sperm having normal 23 chromosomes and only carry Y chromosomes, a pointed nose klienfelter syndrome case will appear.

Rosa eats a peanut butter sandwich for lunch. Peanut butter contains a lot of protein, and bread is mostly starch. Rosa plans to go for a run later this afternoon. Rosa is breathing normally.
What does she need from the food she ate and the air she breathes so that she can go on her run? How do Rosa’s body systems work together to get the molecules she needs into her cells? How do her cells use these molecules to release energy for her body to run?

Fruit flies (Drosophila melanogaster) with a wild-type phenotype have gray bodies and red eyes. Certain mutations can cause changes to these traits. Mutant flies may have a black body and/or cinnabar eyes. To study the genetics of these traits, a researcher crossed a truebreeding wild-typed male fly with a true-breeding female fly with a black body and cinnabar eyes. All of the F1 progeny displayed a wild type phenotype. Which of the following is correct about the traits observed?a. Gray body and cinnabar eyes are dominant.b. Eye color is sex-linked.c. Body color is sex-linked.d. Gray body and red eyes are dominant.
Answer:
d
Explanation:
The correct answer would be that gray body and red eyes are dominant.
The wild type trait is represented by gray bodies and red eyes while the mutant trait is represented by black body and/or cinnabar eyes. A cross between the wild type and the mutant only yield F1 offspring with wild type phenotype. This, thus, means that the wild type trait is dominant while the mutant trait is recessive.
Since the wild type trait is depicted by gray body and red eyes, it means that the gray body and red eyes traits are dominant while the black body and cinnabar eyes are recessive.
The correct option is d.

If the anticodon of a molecule of tRNA has the sequence GAU, what was the original DNA sequence?
Answer:
CTA
Explanation:
DNA to RNa
A---> T
C--> G
RNa to dna
A--> U
C---> G
If the anticodon of one molecule of tRNA contains the sequence GAU, then CTA was the original DNA sequence.
What is DNA sequencing?
DNA sequencing is defined as the laboratory procedure used to determine the exact sequence or order of the four building blocks or bases that make up DNA. Information that is stored in DNA in a code which is formed by arranging the four bases which are adenine, cytosine, guanine and thymine which are identified by letters A, C, G and T in different order.
Within double-stranded DNA, nitrogenous bases on one strand pair with complementary bases on the other strand. A always pairs with T, and C always pairs with G, during DNA replication, the two strands separate into a double helix.
Sequence of tRNA is GAU, so the DNA sequence is CTA as C complements to G, A to T and U to A as in RNA Uracil is present in the place of thymine.
Thus, if the anticodon of one molecule of tRNA contains the sequence GAU, then CTA was the original DNA sequence.

A strain of Drosophila known as dunce produces one-half the amount of cAMP phosphodiesterase found in wild-type flies, which causes a learning defect. Another strain of Drosophila known as rutabaga produces a defective adenylyl cyclase protein (one of the AC types expressed in most cells) and also causes a learning defect. A dunce - rutabaga double mutant fly has relatively normal learning. Explain these curious observations.
Answer:
From the given observations we can say that there are 2 genes that are responsible for normal learning. It is also given that the dunce and rutabaga mutations are the mutations of 2 different genes.
Due to complementation which is a phenomenon of restoration of normal phenotype if mutants are crossed, it is found that the flies have normal learning behavior if both mutants are crossed.
Let's assume that the Drosophila having this learning effect and it is due to genes D and R where D is the normal gene and dd is the case of mutation that results in duncy phenotype. Similarly, Gene R is responsible for normal learning, and rr results in rutabaga phenotype.
Cross between ddRR (duncy) x DDrr (rutabaga)
Gametes - dR x Dr
F1 progeny - DdRr
Thus, in heterozygous cases, a single copy of both wild-type alleles D and R complement each other.
