Answer:
A new specie formed as a result of evolution.
Explanation:
Evolution refers to the change in the characteristics of an organism with the passage of time. in the beginning there is only one single plant and animal specie but with passage of million of years changes occurs in the structure and genotype of the organism and as a result, a new specie was formed. So after millions of years, thousands of new species formed and there is a need for their classification in order to make their study easier. So we can say that evolution broaden the scope of classification.
Which is a malignant disorder of mature antibody-secreting B lymphocytes or plasma cells? Multiple myeloma Hairy cell leukemia Acute lymphoid leukemia (ALL) Chronic myeloid leukemia (CML)
Answer:
The correct answer is Multiple myeloma.
Explanation:
Multiple myeloma is a type of bone marrow cancer caused by a malignant degeneration of plasma cells. Normal plasma cells are part of the immune or immune system, responsible for dealing with infections and diseases of external origin. Plasma cells are normally found in the bone marrow, mixed with other cells of the immune system and with the cell-producing cells of the blood. When there is an infection, the B lymphocytes respond, become plasma cells or plasma cells and produce antibodies (also called immunoglobulins) that help the body fight infection. T lymphocytes respond with various transformations that allow them to directly attack infectious agents or help other types of cells defend the body.

When the blood conce
Explanation:
When the blood ca+ concentration falls below the standard of 4.4-4.5mg/dL,that is below 4.4mg/dL the clinical condition is called hypocalcemia. It is caused by hypothyroidism,due to malfunction of the parathyroid gland.
Generally, Ca+ is needed for contraction of muscles by causing the fusion of the vesicles containing neurotransmitters to the presynaptic membrane for the passage of neuro transmitters to fuse with the receptors on the sarcolemma to initiate muscular contractions by opening of ligand gated Na+. It also interact with the ligand gated sodium ion channels
Generally,Ca+ inhibits depolarization of ligand gated Na+ channels. Thus blocks the opening of these channels and therefore the rate of excitability.Therefore, If the is low serum levels of Ca+,There is increased in the threshold of depolarization because more ligand gated Na+ channels are opened,Thus their is increased excitability of nerves and muscles fibres therefore in the clinical manifestations listed above.
It can be treated with infusion of Ca+ into the blood.

EXPLAIN The scuba diver is a living system. The scuba gear, or self-
contained underwater breathing apparatus, is a system of air exchange.
How are these two systems interacting? What are the inputs and outputs of
these systems?
Pt.I
All living things needs some form of oxygen to live. In talking about a scuba diver, we are talking about a human, who uses their lungs to breathe, and did not develop the ability to breathe under water. Instead, when in a body of water, we tend to hold our breaths until an opportunity arises for us to exchange our carbon dioxide for oxygen.
Take into account the scuba gear. The scuba gear fits the user, and has a number of protection, including the suit counter-balancing any pressure applied by the deep, and the tank providing much needed oxygen to the user during delayed periods within the water.
Pt.II
How does these two systems interact?
Like as a human is breathing on land or even swimming, the human expels carbon dioxide, which forms into "air bubbles" that are then expelled into the water surrounding. The user then draws air from the pressurized air tank, and is able to breathe as such. This allows the user to stay underwater for much longer than just one breathe, and is able to travel farther inside the deep.
Inside this system, the Oxygen is first input into the oxygen tanks, which are then used by the diver. The diver would draw the oxygen from the tank (output), and he will then expel the used air into the surrounding water.

What is Fire?Fire is the rapid oxidation of a material in the exothermic chemical process of combustion, which releases heat, light, and various reaction products. This combustion reaction at certain point called ignition point where flames are produced. Flame is the visible part of fire.
Fire is sub divided into 5 classes based on their causes:
Class A Fires: “Ordinary” Fires
Class B Fires: Liquids & Gases
Class C Fires: Electrical Fires
Class D Fires: Metallic Fires
Class K Fires: Grease Fires or Cooking Fires
Laboratory fires are caused by the ignition of flammable liquid spills or vapors which spread from open containers near ignition sources such as hot plates and burners. This can be prevented by
By minimizing the amount of flammable and combustible liquids outside of flammable liquid storage cabinets. We should never store flammable and combustible liquids in the fume hood.If this exists, we should inform our teacher first, then open the window to avoid smoke in the Laboratory and run for the fire extinguisher.

Answer:
Liver-lung migration
Explanation:
Ascaris lumbricoides is also known as round worm and humans get transmitted through contaminated food and water.
When they are ingested, the hatched larvae then penetrate into the intestinal mucosa and are carried to the liver through the portal venules and are then moved to the lungs . When they are in the lungs they rupture which results in them being coughed up and swallowed. After which they mature, mate and deposit eggs which are excreted and the cycle goes on when humans ingest food contaminated with the eggs.
They cause abdominal pain, nausea and anemia and are treated through drugs such as mebendazole.

In the hierarchy of biological organization, an organ is composed of several ______ interacting and working together.
Answer:
tissues
Explanation:
Tissues(made of cells with specific functions)make organs
In the hierarchy of biological organization, an organ is composed of several tissues interacting and working together.
What are tissues?Tissue is basically a group of or collection of cells with somewhat identical structures that work together as a unit.
The intercellular matrix is basically a nonliving material that encompass the spaces in between the cells. This may be profound in some tissues while being scarce in others.
Tissue is classified into major four kinds namely connective tissue, epithelial tissue, muscle tissue, and nervous tissue.
Connective tissue supports as well as connects other tissues (bone, blood, and lymph tissues). Epithelial tissue serves as a protective layer.
An organ is a collection of tissues that structurally form a functional area specialized to take part in a specific function in biology. Organs include your heart, kidneys, and lungs.
Thus, the answer is tissues.

The synthesis of calcitriol, a steroid hormone secreted by the kidney, is dependent on the availability of a related steroid called cholecalciferol (vitamin D3), which may be synthesized in the skin or absorbed from the diet.
a. True
b. False
Answer:
True.
Explanation:
Vitamin D is a fat soluble vitamin that is responsible for fostering the absorption of calcium, magnesium and phosphate in the body.
The synthesis of calciferol is dependent on the availability of a related steroid called cholecalciferol (vitamin D3), which may be synthesized in the skin or absorbed from the diet because keratinocytes of the epidermis and fibroblasts of the skin is response for producing vitamin D3(calciferol) by absorbing it from ultraviolet light when during exposure to UV B photons which protolyses provitamin D3 to pre vitamin D3 in the human body.

is there only one way to conduct a scientific experiment why or why not
Answer:
there is more than one mode to conduct an experiment in order to obtain the same results
Explanation:
The scientific method is a methodology used to minimize the bias in the experimentation procedure in order to test a given hypothesis. The scientific method has several steps:1- to raise a hypothesis, 2-to design the experiment, 3- to perform the experiment, 4-to collect data and 5-to analyze results (conclusions). The main aim of the experiment is to obtain data that can be used to confirm (or reject) the hypothesis, which must be testable and falsifiable to be valid. In consequence, the scientific method can be cataloged as an iterative method because different experiments can lead to the same results.
A scientific experiment can be conducted in different ways, with the aim of trying to check the theories and hypotheses, to observe the results of the same.
An experiment is defined as that process by which one or more independent variables are intentionally manipulated to verify or correct the postulates of the hypotheses that have been created. Its goal is to accumulate reliable information.
Scientific experimentation collects the different methods / ways used by researchers to test their theories and assumptions regarding their objects of study, through the repetition of certain phenomena observed in nature, in the controlled environment of the laboratory.
For a scientific experiment to be valid, however, it must comply with the steps of what is contemplated in the scientific method: a series of logical connections and steps to follow to study a phenomenon objectively and verifiably.
Therefore, we can conclude that there are more than one way to conduct a scientific experiment for the verification of the hypothetical knowledge of the researchers following the steps in the scientific method.
