Answer:
The bones of a synovial joint are surrounded by a synovial capsule, which secretes synovial fluid to lubricate and nourish the joint while acting as a shock absorber. The ends of the joint bones are covered with smooth, glass-like hyaline cartilage which reduces friction during movement.

[email protected] The answer to your question is B.
Answer:
The answer is option "B"
Explanation:
DNA is comprised of a set of genes that dictates a given trait. The genes themselves are comprised of alleles that allow for variations and differences in the trait that the concerned gene is responsible for. In the case of D. Melanogaster, there is an allele that allows for resistance to pesticides such as DDT. The two samples that are referred to in the question are differentiated on the basis of the amount of time that has lapsed since the start of significant DDT usage. So at the time when widespread DDT usage was not in place, the sample showed no DDT resistant alleles. With the passage of time in which DDT usage grew, the resultant effect as evidenced from the later sample indicated a significantly higher percentage of DDT resistant allele. This means that the ability of this species of fruit flies to survive, referred to as their evolutionary fitness, increased only after use of DDT increased. This means that DDT resistance trait changed as a natural response to the introduction of a different climate thereby allowing subsequent offspring of fruit flies to boast of higher numbers of alleles that have DDT resistance capacities thus allowing them to survive.
The Structure of Prokaryote and Eukaryote Cells
During the 1950s, scientists developed the concept that all organisms may be classified as prokaryotes or eukaryotes. The cells of all prokaryotes and eukaryotes possess two basic features: a plasma membrane, also called a cell membrane, and cytoplasm. However, the cells of prokaryotes are simpler than those of eukaryotes. For example, prokaryotic cells lack a nucleus, while eukaryotic cells have a nucleus. Prokaryotic cells lack internal cellular bodies (organelles), while eukaryotic cells possess them. Examples of prokaryotes are bacteria and archaea. Examples of eukaryotes are protists, fungi, plants, and animals (everything except prokaryotes).
Answer:
Peer Review
Explanation:
Peer review is a process where by, professionals or colleagues in a particular discipline with equal qualifications and abilities crosscheck the findings of fellow colleagues before the findings can be published. Peer review can be done in many disciplines. For example, we could have the medical, technical, and scholarly peer reviews.
Peer review is important because it helps to confirm the accuracy of findings and also provide a means to regulate the activities of scientific experts. Peer review is done anonymously, which means that the identity of those doing the review is not revealed. This would help to eliminate bias.
