Answer: Option (d) is the correct answer.
Explanation:
Nucleus of an atom consists of protons and neutrons. Protons are positively charged and neutrons have no charge. So, due to the like charges of protons there occurs electrostatic force of repulsion inside the nucleus of the atom.
But due to similar number of neutrons and protons a force that is able to bind both of them together is known as strong nuclear binding energy.
This force is strong enough that it is able to overcome electrostatic force of repulsion. But when there is great difference in the number of protons and neutrons then binding force is not strong enough.
Hence, the atom becomes unstable and undergoes radioactive decay. So, this means weak forces are responsible for radioactive decay.
Thus, we can conclude that the statement which best describes Yanni’s error is that the strong force is responsible for radioactive decay.
B
Every living thing makes energy through respiration and plants use solar energy during respiration.
believe the correct answer from the choices listed above is option A. The two principal ways to describe Earth’s structure are based on the chemical composition and thickness of layers. Since Earth is a layered structure, it is viewed according to its different chemical composition and the thickness.
Highly porous and permeable
Explanation:
Compared to other types of rock layers, an aquifer is highly porous and permeable.
Aquifers are always the target when prospecting for ground water in a formation.
- Porosity is the amount of void spaces in a rock.
- Aquifers are highly porous .
- Permeability is the inter-connectivity of the void spaces and their ability to transmit fluids.
- Aquifers have very high permeability compared to other rock types.
In terms of permeability and porosity, an aquifer is higher porous and permeable.

Innate: keratinized epithelium
stratified squamous epithelium hypodermal areolar connective tissue antigen presenting cells major histocompatibility complexes complement (antibody -dependent pathway )
Innate or non-specific response is the first defense against invaders. Components of this response include physical (e.g. skin . mucosa) and chemical barriers against pathogens and cells such as Natural Killer cells, macrophages, neutrophils, dendritic cells, mast cells, basophils, eosinophils. Innate response reacts immediately.
Adaptive: immunoglobulin plasma cells agglutinin
helper t cells memory t cells cytotoxic t cells cd4+cells
t lymphocytes
Adaptive immune response or specific response is specific to the pathogen presented and mediated by lymphocytes, B and T cells. Adaptive immune response creates immunological memory after the first, initial l response to a specific pathogen which leads to enhanced response.
