In wild populations, evolution is often caused by natural selection. Based on what you have observed, how does natural selection occur?
Answer:
Organisms with heritable (genetically determined) features that help them survive and reproduce in a particular environment tend to leave more offspring than their peers. If this continues over generations, the heritable features that aid survival and reproduction will become more and more common in the population.

Answer:
Tissue is a group of cells that have similar structure and that function together as a unit. primary types of body tissues include epithelial, connective, muscular and nervous tissues. Epithelial tissues form the covering of all body surfaces , ine body, cavities and hollow organs, and are the major tissues in glands.
A tissue is composed of a group of cells that are determined to play a specific function. The Cytoplasm is a dense gel-like material that is filled within the cell.
What is Cell theory?Cell theory was proposed by M. Schleiden and T. Schwann in 1838. According to them, there are three postulates of cell theory that are as follows:
All living organisms whether plants or animals are made up of cells.A cell is the smallest unit of all living organisms.The cell is the structural and functional unit of life.Cell theory was further refined by German biologist Rudolf Virchow in 1855. According to him, all cells are arising from pre-existing cells. The Cell wall generally protects the cell and it is most commonly found in plants, animals, bacteria, etc.
Inside the cell, there are various organelles present that perform specific functions for the survival of the cells. The nucleus is known as the brain or controlling center of the cell, which transmits genetic information from one generation to the next.
Therefore, each of the above-given term is justified above.

k. Tendon 10. The cordlike part that attaches a muscle to a bone
l. Transverse (T) tubule reticulum 1. Membranous channel extending inward from muscle fiber membrane
Explanation:
A muscle has around it epimysium, which is connective tissue. Inside the epimysium, there are fascicles, and around each of them, there is perimysium. Inside every fascicle, there are muscle fibers, each of them is surrounded by a connective tissue called endomysium. Between every muscle, there is also connective tissue and is called fascia. The connective tissue has vessels and provides support.
The muscle cells are called fibers. They have a membrane, the sarcolemma, a cytoplasm, the sarcoplasm, and a sarcomere, which is the functional unit of the fiber, in other words, it is the structure responsible for the contraction. The sarcomere has different bands made of thick filaments of myosin and thin filaments of actin. They are the light and dark striations that go from disc z to disc z when we observe the sarcomere under a special microscope. The sarcoplasmic reticulum is the place that stores the calcium necessary for the contraction of the fiber, and the transverse tubule reticulum allows the contraction of various fibers since they spread the action potential amongst fibers.
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.

The blue people of Troublesome Creek Kentucky were genetically isolated from the rest of the world for generations. A rare recessive allele that causes people to have a blue tone to their skin, methemoglobinemia, became disproportionately common within this population by way of their genetic isolation. In the last few decades new roads opened leading to the end of this communities isolation. To the surprise of many, the methemoglobinemia phenotype disappeared along with their genetic isolation. Which of the following may best explain the apparent disappearance of this once common trait?
a. Methemoglobinemia did not confer any physical advantage so that the trait was selected against.
b. Methemoglobinemia was probably lethal and all those that carried this trait died and did not have a chance to pass on this trait to future generations.
c. Those that had the traits simply did not have descendents.
d. With the end of genetic isolation gene flow took place.
Answer:
The correct answer would be - d. With the end of genetic isolation gene flow took place
Explanation:
It is given that people of Troublesome Creek Kentucky were isolated and have a rare recessive allele that results in a blue tone to their skin. However, later these isolated people connected with the people from outside, and due which allow them to intermate. Intermating among populations from isolated and people from outside leads to gene flow.
Methemoglobinemia was present in the isolated population as they had both recessive alleles in their genotype and other hand people from outside might have heterozygous or both dominant allele genotypes that make them free from this disorder.
Due to the intermating and gene flow, the number of heterozygous conditions rises and after many generations slowly methemoglobinemia could have disappeared due to the masked recessive allele.

There are ongoing arguments among taxonomists as to which phyla represent the closest relatives of phylum Annelida. Some propose that these worms share a common ancestor with the arthropods (crabs, insects etc.). However, the majority continue to keep the annelids lumped together with the Lophotrochozoa. The reasons for this are many but probably the least disputed comes from:______.
a. the segmented body plan of the annelids.
b. molecular analysis.
c. metamerism.
d. schizocoelous origin of the coelom.
Answer:
a. the segmented body plan of the annelids
Explanation:
lophotrochozoan is a taxonomy of animals that includes annelids, bryozoans, and brachiopods. This taxonomy of creatures was defined in 1995 as the last ancestor of the taxa of worms, mollusks, and annelids. Their classical definition depends on the topology of the spiral tree of life. Annelids have a segmented body part wherein the external morphological features are repeated in every body segment. It allows the animal to become bigger and makes their movement more fat and efficient.Answer:

Sickle cell anemia is a genetic condition that occurs because of a single point mutation in the DNA gene for hemoglobin. How is this mutation expressed in humans?
A.) The protein coded by the DNA has a different amino acid sequence
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.

A new protein factor named PF2 was recently isolated from mammalian cell nuclei. Among other protein domains, PF2 exhibits an RPD3-interacting domain (RPD3 contains the catalytic activity of the HDAC B complex) and a TFS-interacting domain (TFS is a DNA binding protein). PF2 does not have a DNA binding domain, however. Predict a likely function of PF2 and justify it. The importance of both domains should be explained.
Answer:
The likely functions of PF2 includes binding of several protein factors and DNA structure formation
Explanation:
PF2 contains RPD3 and TFS domains

B. Seasonal Changes have no impact on these organisms
C. During winter months the Diatom and zooplankton population completely die off due
to the lack of sunlight.
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.
