Which of the following is not an example of where primary succession typically occurs?
After a fire
A retreating glacier
Emerging islands
Formation of new lakes
Answers
Answer:
After a fire
Explanation:
Primary succession is one of the two types of ecological succession in which a barren area of land (with no soil) is colonized by organisms called PIONEER SPECIES for the very first time.
Primary succession is characterized by a BARREN area that had no form of previous growth or colonization. These barren area can include a retreating glacier, an emerging islands or the formation of new lakes.
Note that, the succession that occurs AFTER A FIRE or any form of environmental disturbance is SECONDARY SUCCESSION.

All theories are hypotheses, but not all hypotheses are theories. Francis wants to know if a specific hypothesis he is researching is a theory. Which describes how Francis would know the hypothesis is a theory?
He could restate the hypothesis as a fact and no longer an explanation.
He could determine whether the hypothesis is based on repeated experiments.
He could perform the experiment and adjust data to match the desired results.
He could design and perform a new controlled experiment to test the hypothesis.
Answers
Answer:
He could determine whether the hypothesis is based on repeated experiments.
Explanation:
A theory is a hypothesis that has been proven correct by many expirements.
Francis could design and perform a new controlled experiment to test the hypothesis to determine whether it is a theory. Therefore, the correct statement is option D.
What is a theory?A hypothesis is a scientific explanation for a phenomenon that is based on prior observation. However, a theory is a well-supported and widely accepted explanation for a natural phenomenon that has been tested and based on scientific fact.
A hypothesis has the potential to become a theory if tested through carefully designed and controlled experiments by collecting data needed for the experiment.
If the results of an experiment conducted by Francis are consistent with the hypothesis, the information can be used to develop a theory that can be used to explain a broader range of phenomena. However, if the results are not by the hypothesis, Francis cannot consider the hypothesis as a theory that must be supported by evidence.
Therefore, Francis needs to design and perform a new controlled experiment to test the hypothesis to determine whether it is a theory.

The frequency of a lethal allele in a population is greatest when it is: Group of answer choices dominant manifested in infancy recessive co-dominant
Answers
Answer:
recessive
Explanation:
A lethal allele is a gene variant associated with a mutation in an essential gene, which has the potential to cause the death of an individual. In general, lethal genes are recessive because these alleles do not cause death in heterozygous individuals, which have one copy of the normal allele and one copy of the allele for the lethal disease/disorder. In recessive lethal diseases, heterozygous individuals are carriers of the recessive lethal allele and can eventually pass the 'defective' allele on to offspring even though they are unaffected; whereas dominant lethal diseases are caused by dominant lethal alleles, which only need to be present in one copy to be fatal. In consequence, the frequency of recessive lethal alleles is generally higher than dominant lethal alleles because they can be masked in carrier individuals. Some examples of human diseases caused by recessive lethal alleles include, among others, Tay-Sachs disease, sickle-cell anemia, and cystic fibrosis.
The frequency of a lethal allele in a population is greatest when it is: C. recessive.
A lethal allele can be defined as an allele that is responsible for the death of a living organism, especially by preventing its development. Thus, a lethal allele causes a complete mortality in the living organism carrying it, in a hom-ozygous condition.
Basically, a lethal allele is recessive in nature because it is expressed in the phenotype of an organism. Some examples of diseases caused by lethal alleles in humans are:
Cystic fibrosisSickle-cell anemiaAchondroplasiaIn conclusion, a lethal allele that is recessive has the greatest frequency in a population.

What is the correct order of the levels of organization in animals from smallest to largest?
Answers
Answer:
Molecules, cells, tissue, organ, organ system, organism, population, community, ecosystem, and biosphere are in the correct order of the organization's levels.
Explanation:
Molecule: Atoms, the smallest unit of chemical elements are built up of molecules. You can find it in any matter, whether it lives or not. The most fundamental structures of biological creatures are molecules. Biochemistry and molecular biology are two biological fields focused on this level.
Cell: A cell is the basic unit of life. Two types of cells exist plant cells with a stiff cell wall consisting of cellulose molecules and animal cells with a flexible cell membrane. Cell biologists examine problems like metabolism and other structure and functional questions within and between cells.
Tissue: Tissue consists of cells working together to accomplish a goal. Some tissues include muscle, connective tissue, and neural tissue. Examples of biologists working at this level are histologists.
Organ: An organ is a tissue system that works at bigger scales together to perform specified work in the body of an animal. Brain, heart, and lungs are examples of organs. Anatomy is an example of a specialty in biology which concerns this level.
Organ system: An organ system is a group of bodies that work together to fulfill certain activities of the body. Air systems are used to inhale oxygen and release carbon dioxide in animals, for example, by the lungs, respiratory tract, and muscles. The function of the corpus when working jointly is studied by physiologists. Although physiologists can work at any level, they commonly address queries about organ systems.
Organism: An organism is an autonomous and recognized person. The organisms might be single-cell or multi-cell organisms consisting of organisms and organ systems, as well as bacteria, amiable, or creatures. An example of a multi-cellular organism is a human being.

In most cases of multiple myeloma, the excess antibodies found in the blood all share an identical protein sequence (thus they have the same structure). Consider such a case where all of the antibodies are identical and think about the cell(s) of origin. How many different B cell clones gave rise to this immune cancer?
Answers
Answer: One single B cell clone gave rise to this immune cancer.
Explanation:
The body's cells divide and grow in a completely regulated manner, following an orderly cell cycle that indicates when a cell should die by apoptosis. With this regulation, it is controlled that there are no aging or mutated cells that grow and affect the organism. Cancer is a genetic disease caused by changes in these genes that control how our cells function. These changes, genetic mutations, can occur randomly in the body or can be inherited from parents. When a cell has its functions altered, they begin to grow out of control and in doing so, form masses called tumors that consume the body's resources and energy and crowd out normal cells, preventing them from fulfilling the biological functions necessary for life. Practically, any cell can become a cancer cell and migrate to other areas of the body.
Multiple myeloma is a type of plasma cell cancer. These cells are found in the bone marrow (tissue inside the bones) and are an important component of the immune system, which is made up of several types of cells that work together to fight pathogens and disease. Some cell types are B and T lymphocytes, and myeloid cells such as macrophages, dendritic cells, etc. When B cells respond to an infection with the participation of T cells that present pathogen-derived antigens to them, they mature into plasma cells. Plasma cells produce antibodies that help the body attack and destroy pathogens as well as cancer cells. These antibodies are proteins that bind to antigens that are also proteins found on the surface of the pathogens or cells to be attacked and "mark" them for destruction by other types of immune cells, such as macrophages or neutrophils.
When the plasma cells become cancerous and grow out of control, this is called multiple myeloma, and the mutated plasma cells produce abnormal antibodies. The overgrowth of plasma cells in the bone marrow can crowd out normal blood cell-producing cells, causing low blood cell counts. This can cause anemia which is characterized by a shortage of red blood cells, and thrombocytopenia which means a low level of platelets in the blood causing increased bleeding and bruising. Another condition that can occur is leukopenia (a shortage of normal white blood cells), which can cause problems fighting infections.
Then, the abnormal antibodies produced by the cancerous plasma cells will have the same amino acid sequence and therefore the same structure. Remember that an antibody is a protein, and proteins are a polymer of amino acids. This amino acid sequence is determined by the genes since each gene consists of a sequence of nitrogenous bases and every three bases read by the ribosomal apparatus (the one that synthesizes proteins), an amino acid is synthesized. Therefore, if we consider that cancer originates from a single cell that suffered a mutation in its genes and began to divide in an uncontrolled manner, the daughter cells (which are genetically identical to the mother cell) derived from this mutated cell will have the same genes (in this case, altered because they divide and grow in an uncontrolled and deregulated manner). This tells us that a single mutated B cell gave rise to this cancer.

explain the concept of mutation and how mutations can translate to a loss or gain of function in an organism
Answers
A mutation is a change in a DNA sequence. Mutations can result from DNA copying mistakes made during cell division, exposure to ionizing radiation, exposure to chemicals called mutagens, or infection by viruses. Germ line mutations occur in the eggs and sperm and can be passed on to offspring, while somatic mutations occur in body cells and are not passed on.
Recessive mutations inactivate the affected gene and lead to a loss of function. For instance, recessive mutations may remove part of or all the gene from the chromosome, disrupt expression of the gene, or alter the structure of the encoded protein, thereby altering its function.

ChlorophyllExplanation:
Chlorophyll, the primary pigment used in photosynthesis, reflects green light and absorbs red and blue light most strongly.
In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll.
Answer:
B) Chlorophyll
Explanation:
The chloroplasts, which contain the green pigment chlorophyll, are where photosynthesis takes place. Chlorophyll is the pigment that gives plants their distinctive color. It works by collecting the energy in the sunlight that strikes the plant. Because grass requires photosnthesis to create glucose, which is required for growth inside the grass, photosynthesis is critical to life on Earth. As a result, creatures that eat the grass get energy, and so on. As a result, photosynthesis is the mechanism through which energy is introduced into an environment.
