The bicep muscle has an attachment point at the shoulder and one in the upper forearm. Look at these images of the bones of the arm. Imagine that the point of the arrow is where the force of the biceps muscle is applied to the bone.
Which image would result in the biceps muscle contracting and the forearm being lifted?
A
B
C
D
Answers
Option B represents the image would result in the biceps muscle contracting and the forearm being lifted.
What is Biceps muscle?This is the muscle which is found in the front region of the upper arm and is involved various forms of movement.
Contraction means shortening of the biceps which is made possible when a force acts upwards thereby resulting in the forearm being lifted. This is why B was chosen as the most appropriate choice.

Labrador retrievers' fur color is controlled by two alleles, E and B. Any dog with the ee_ genotype d evelops into a yellow lab, while B_E_ dogs become black labs and bbE_ dogs become chocolate labs. This is an example of __ .
Answers
This is an example of recessive epistasis.
Here the presence of recessive allele ee at one locus inhibits the phenotypic effect of genes at the B locus.
As it is mentioned in the question above the ee__ genotype develops into a yellow lab.
Dominant B gene can produce the black coat color phenotype only when a dominant allele E is also present.
If the genotype is B_ee, then yellow coat color would be produced.
Therefore the recessive allele e in homozygous ee form masks the effect of the dominant B allele.
Recessive epistasis is the phenomenon in which the expression of one gene pair is depending on some other gene pair. In different words, one gene must be grown to become one for any other gene to be expressed.

A researcher investigates a recently discovered species of plant. The plant has vascular tissues and exhibits a sporophyte and a gametophyte generation, but lacks seeds. How should the researcher classify the plant?
Answers
The plant contains vascular tissue and has an alternation of generation. But, it lacks seeds. So, the plant is a Pteridophyte.
Vascular tissues are absent in thallophytes and bryophytes. They are found in pteridophytes, gymnosperms and angiosperms. The sporophyte and gametophyte generation is common in bryophytes and pteridophytes. Seeds are produced in plants that come under the group gymnosperms and angiosperms. The presence of seeds is the main characteristic of these groups. Thallophytes, bryophytes and pteridophytes lack seeds. The reproduction in plants that comes under these groups occurs with the help of spores.Thus, the recently discovered species of the plant should be classified based on the presence of vascular tissues, gametophytes and sporophytes. As pteridophytes contain vascular tissues, sporophytes and gametophytes and lack seeds, the plant is a pteridophyte

The question is incomplete. Please read below to find the missing content.
Selection is usually strongest in the male of the species. D) because sperm are small and plentiful, while eggs are large and energy-rich.
Phenotype refers back to the observable traits of an organism as a multifactorial effect of genetic trends and environmental influences. The organism phenotype includes its morphological, biochemical, physiological, and behavioral residences.
A person's genotype is their specific collection of DNA. extra especially, this term is used to refer to the two alleles a person has inherited for a selected gene. Phenotype is the detectable expression of this genotype – a patient's clinical presentation.

Answers
The term for the part of the protective areas or tip of the DNA that grow shorter every time the cell divides is known as a telomere
Toward the ends of each and every chromosome in our body lies a long chain of repetitive monotonous DNA called a telomere, which goes about as a protective cap. A telomere is a region of monotonous repetitive DNA groupings toward the ends of a chromosome. Telomeres shield or protect the ends of the chromosomes from getting frayed or tangled. When a cell separates or divides, the telomeres become marginally more limited. In the end, they appear so short that the cell can never again divide effectively, and the cell dies.

Answers
The body's musculoskeletal system has three types of machines that produce movement. These three types of machines are known as levers, pulleys, and axles
Bones, Cartilage, Ligaments, Tendons, and Connective tissues together constitute the musculoskeletal system. The body's musculoskeletal system involves levers, pulleys, and axles as their three main mechanical components.
The levers: Bones in the human body function as levers, joints form the axis of rotation whereas the muscle generates the force for the motion. These three works constitutively form the general lever system in the body. However, the arrangements of these three components of the lever system can vary greatly depending upon the type of joints involved and the locus and type of movement required.
The Pully: This system of the body is employed to provide direction to the applied force or to change the direction of the applied force. This can work individually or in a combination with systems that makes the movement easier.
The Axles: This system is responsible for managing the angular acceleration or torque, and magnitude of movement. It is generally present in association with the wheel which holds for the force arm which has the mechanical advantage over the axle.

In order to improve fat digestion, large fat globules must first be dispersed into smaller droplets in a process called __________.
Answers
In order to improve fat digestion, large fat globules must first be dispersed into smaller droplets in a process called emulsification.
What is emulsification in the digestive system?Fat emulsification is the process of increasing the surface area of fats in the small intestine by grouping them into small clusters. Large lipid globules are split up into a number of smaller lipid globules. In the chyme, these tiny globules are widely dispersed rather than aggregating into larger groups. Hydrophobic compounds include lipids. Bile salts, are present in bile and have both hydrophilic and hydrophobic sides.
Due to the fact that lipases can only effectively act on lipids when they are broken down into small aggregates, emulsification is crucial for the digestion of lipids. The lipids are converted into fatty acids and glycerides by lipases.

Twenty four percent of the bases of a double- stranded DNA molecule are adenine (A). What percentage of its bases would be expected to consist of guanine (G)
Answers
If the percentage of adenine bases is 24% then the guanine base percentage will be 26% according to Chargaff's rule.
DNA consist of millions of base pairs in the form of purines [Adenine (A) Guanine (G)] and pyrimidines [ thymine (T) cytosine (C) and uracil (U only in RNA in place of T).Adenine is complementary to thymine and uracil while guanine is complementary to cytosine.According to Chargaff's rule ( A + G = T + C ), DNA from all cells of all creatures should have a 1:1 ratio of pyrimidine and purine bases. More specifically, the amounts of guanine and adenine should be equal to cytosine and thymine, respectively.
hence if the percentage of Adenine (A) is 24% then the complementary base Thymine (T) will also be 24%
Now A + T = 24 + 24 = 48% out of 100
the remaining 52% is composed of GC i.e., 26 % + 26%
Hence Guanine will be 26%

Female cones are distinguishable from male cones by their bigger size and their location closer to the crown of the tree.
