Answer:
A virus
Explanation:
A virus requires a host cell to implant proteins into so that the host cell can create new virus cells. The virus essentially hijacks the cell.
All other listed cells can create new copies of their own proteins.
Cheers.
A virus does not possess the tendency to synthesize their own proteins.
• Viruses are not animals, plants, or bacteria, however, they are the quintessential parasites of the living kingdoms.
• Viruses are not living organisms as in the absence of a host cell, they cannot perform their life-sustaining activities of reproduce.
• They cannot produce their own proteins, as they are devoid of ribosomes and must utilize the ribosomes of their host cells to convert the viral mRNA into the viral proteins.
Thus, the correct answer is a virus.

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.

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.

Explain why the surface of water in a container is not flat but curved?
Answer:
it is due to high surface tension of water
Explanation:
However, for small amounts of water (like in water droplets), surface tension forces become dominant, making the water surface assume a curved, rather than flat shape. In free fall conditions (like in a spacecraft) surface tension causes even larger amounts of water to assume a spherical shape.
When the molecules of the liquid are drawn to the molecules of the container, a concave meniscus forms, which is what you generally witness. A glass tube and water cause this to happen. When molecules, like those of mercury and glass, are more attracted to one another than to the container, a convex meniscus is created.
Why is the surface of water curved?
The nature of the glass and water molecules themselves is to blame, I suppose. Polar molecules, which have positively and negatively charged ends, make up water. Due to the law of attraction between opposites, positive and negative sides of molecules are drawn to one another.

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.

these organisms obtain energy through chemosynthesis rather than photosynthesis
Answer:
Autotrophs
Explanation:
Some rare autotrophs produce food through a process called chemosynthesis, rather than through photosynthesis. Autotrophs that perform chemosynthesis do not use energy from the sun to produce food. Instead, they make food using energy from chemical reactions, often combining hydrogen sulfide or methane with oxygen.
The organisms obtain energy through chemosynthesis rather than photosynthesis are called as autotrophs.
What are autotrophs ?The autotrophs are the organisms that produce their own food material by self by using energy from sunlight or a chemical source to drive the process. Plant are the most familiar autotrophs, but there are many autotrophs are present.
An autotroph is an organism that can produce its own food material by using carbon dioxide, light, water or other chemicals. They are also called as producers.

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.

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.
