Answer:
Directional selection
Explanation:
Natural selection is the process by which environment selects from a population of organisms which individuals are better suited and adapted to that environment. There are three types of natural selection namely: directional selection, disruptive selection and stabilizing selection.
Directional selection is the type of natural selection in which only one extreme (phenotype) of a population is favored over the other extreme and intermediate individuals. This is the case in the example given in the question where among a group of white, grey, and black rabbits that lives in Alaska, environment selects the white rabbits (one extreme) from wolf predation, hence, causing the white rabbit population to increase and be favored.
You are studying a new gene "X" that you think controls skin color in Bearded Dragons. In order to determine what gene X does you need lots of gene X DNA to work with. So, you decide to amplify it through the process known as PCR. You have a forward and a reverse primer that have been designed to gene Xf – a gene in frogs that is similar to the one found in the Bearded Dragon. You are pretty sure that these two primers will work in Bearded Dragons, so you decide to go ahead with the PCR. In frogs, the Forward Xf primer binds gene Xf between nucleotides 32 and 47. The Reverse Xf primer binds between nucleotides 1110 and 1135. What size PCR product would these two primers create if they amplified the frog gene Xfp
Answer:
The correct answer is - 1103 bp.
Explanation:
PCR or polymerase chain reaction is a process that uses a primer to amplifying the desired segments of DNA molecules. It is a technique that can amplify a million copies of the DNA segment.
given:
forward primer binds from - 32 to 47
reverse primer binds from - 1135 to 1110
PCR product would be between - 32 to 1135
So, product size would = 1135-32 = 1103.
Thus, the correct answer is - 1103.
Using this illustration as a guide, indicate the level one would need to drill to gain a sample containing the highest ratio of parent rock in comparison with organic material.
horizon C
horizon A
horizon B
horizon O
Answer:
horizon C
Explanation:
The horizon C has the highest ratio of parent rock as compared to organic matter. This horizon starts after horizon B and present above the bed rock. This horizon consists of weathered and partially decomposed rocks. It is the actual layer of soil of that place whereas the other horizon A and B comes with the passage of time when the wind bring the soil particles and these particles deposits on this layer of the soil making horizon A and B.
A cleft chin in humans is coded by the dominant allele C. A chin without a cleft is coded by the recessive allele c. A man with a cc allele combination for the trait produces a zygote with a woman with a Cc allele combination for the trait. Which allele combinations could occur in the zygote?
Answer:
The allele combinations are: Cc, cc, Cc, cc
Phenotypically there is a 50% chance that the child will be born with or without the cleft
The allele combinations that could occur in the zygote is Cc or cc.
What is an allele combination?An identification of the specific alleles found at each of the relevant mouse loci on the two homologous chromosomes (i.e., all allele pairs of a genotype). One or more allele pairs can make up an allele combination.
Genetic linkage is the capacity of a chromosome to transmit alleles that are near to one another as a whole unit through meiosis. Inheritance of traits is also understood by this principle. It is useful in locating the genes that are in charge of characteristics and diseases.
The person is homozygous for the allele if the two alleles are the same. The person is heterozygous if the alleles are different.
Therefore, the zygote may include the allele combinations Cc or cc.

Answer of the question
Your friend runs out of gas and you have to help push his car. Discuss the sequence of bones and joints that convey the forces passing from your hand, through your upper limb and your pectoral girdle, and to your axial skeleton.?
Answer: The sequence of bones and joints that convey the forces include: From metacarpal bones --> carpal bones --> midcarpal and radiocarpal joints --> radius and ulna bones --> elbow joint --> humerus --> glenohumeral joint --> scapula --> acromioclavicular joint --> clavicle --> sternoclavicular joint --> sternum.
Note: the sign (-->) represents "into the".
Explanation:
The skeletal system is made up of bones of the skeleton, their joints and the skeletal muscles which acts together to bring about different movements in the body. The skeleton of a vertebrate had the following basic plan:
--> The axial skeleton: this forms the main central axis. This is made up of the skull,vertebral column, breastbone (sternum), and ribs.
--> The appendicular skeleton: this consists of parts that articulates with the axial skeleton. This is made up of the forelimbs, hindlimbs, pelvic and pectoral girdles.
From the question given, in an attempt to help push the friend's car, the sequence of bones and joints that convey the forces will pass from METACARPAL BONES of your hand into the CARPAL BONES at the base of your hand. Forces will then pass through the MIDCARPAL and RADIOCARPAL JOINTS into the RADIUS and ULNA bones of the forearm. These will pass the force through the ELBOW JOINT into the HUMERUS of the arm, and then through the GLENOHUMERAL JOINT into the SCAPULA. The force will travel through the ACROMIOCLAVICULAR JOINT into the CLAVICLE, and then through the STERNOCLAVICULAR joint into the STERNUM, which is part of the axial skeleton.
As one pushes against the car, the forces will pass in a sequential manner from the bones of the hand to the bones that are part of the axial skeleton.
• Forces will pass from the metacarpal bones of the hand into the carpal bones at the base of the hand, when one pushes against the car.
• After that the forces will then mediate via the radiocarpal and midcarpal joints into the ulna and the radius bones of the forearm.
• Then the force will move via the arm's humerus, and then via the glenohumeral joint into the scapula.
• The force then will mediate via the acromioclavicular joint into the clavicle, and then via the sternoclavicular joint into the sternum, that is, the part of the axial skeleton.
Thus, in the given case, force gets mediated through the bones of the hand and towards the bones of the axial skeleton in a sequential manner.

B.) The chromosome caring this gene changes shape during cell reproduction
C.) The hormones in the bladder change by increase differences in genes
D.) The carbohydrate code by the DNA has a different structure
Answer:
B.) The chromosome carrying this gene changes shape during cell reproduction
Explanation:
According to this question, Sickle cell anemia is a genetic condition that occurs when the HBB gene that codes for haemoglobin protein undergoes a point mutation. Mutation alters the genetic sequence of a gene.
This mutation expresses itself when the chromosome 11 carrying the mutated gene changes shape during cell reproduction. Normal Red Blood Cell has a disc-shaped structure, however, this mutation causes a change in shape of the chromosome involved.

D. Due to the availability of solar energy, Diatom mass peaks in July.
Answer:
D. Due to the availability of solar energy, Diatom mass peaks in July.
Explanation:
Diatom are the photosynthetic algae which prepare food for themselves from the solar radiation just like plants. These diatoms produce more biomass or vegetation in the summer season mainly in July because availability of more sunlight in the Barents sea region while on the other hand, less biomass in the winter season due to low temperature and solar radiation which also effects the population of zooplankton organisms. So we can conclude that seasonal changes have a great impact on the organisms living around the Barents Sea.
