Answers
The condition you're describing is Myasthenia Gravis.(C)
Myasthenia Gravis is an autoimmune neuromuscular disorder characterized by fatigue and progressive muscle weakness, especially affecting the face and throat muscles. It occurs when the body's immune system mistakenly targets and damages the neuromuscular junctions, where nerve cells and muscle fibers meet.
This damage disrupts communication between nerves and muscles, resulting in muscle weakness. Symptoms may include difficulty swallowing, speaking, or breathing, drooping eyelids, and weakened facial muscles.
Treatment options typically involve medications that improve nerve-to-muscle communication or suppress the immune system, and in some cases, surgery to remove the thymus gland.(C)

After enjoying a meal of fish and chips, you notice your shirt has an oily stain on it. Why won't the oily stain come out when you dab at it with just water?
Answers
Oil and water don't combine because oil is nonpolar and water is polar. Therefore, when you dab at it with just water after enjoying a meal of fish and chips, you notice your shirt has an oily stain on it.
Oil and water don't mix. They're supposedly immiscible. This is due to the fact that water is a polar molecule, which means that one end of it has a positive charge and the other a negative charge. The reason why water molecules cling together is because one water molecule's positive end is drawn to another's negative end.
A molecule of oil has a non-polar structure. Its charge does not have a positive or negative end, but is evenly balanced.
As a result, the two never mix because water molecules are more attracted to each other than oil molecules are, and the opposite is true for oil molecules.

DNA holds the instructions or genetic code for protein synthesis, RNA is the messenger for protein synthesis, and the ribosome has the machinery for protein synthesis.
What is DNA?
DNA stands for Deoxyribonucleic Acid. It is a molecule that carries the genetic information and instructions for the development, function, growth, and reproduction of all living organisms.
DNA is made up of four different types of nucleotides: adenine (A), thymine (T), guanine (G), and cytosine (C). The sequence of these nucleotides determines the genetic code and instructions for building and maintaining an organism's body. The nucleotides are joined together by chemical bonds to form a double-stranded helix structure.
During protein synthesis, the DNA code is transcribed into RNA, which carries the instructions to the ribosome. The ribosome reads the RNA code and uses it to assemble a chain of amino acids in the correct order to form a protein. The process of protein synthesis is complex and requires the coordinated actions of several different molecules and cellular structures.

the structural unit of compact bone (osteon) resembles the growth rings of a tree trunk (true or false)
Answers
True, the structural unit of compact bone, known as the osteon or Haversian system, does resemble the growth rings of a tree trunk. In both cases, the structure is organized in concentric layers or rings.
Osteons are cylindrical structures that contain a central canal called the Haversian canal. Around this central canal, layers of calcified matrix called lamellae are deposited in a concentric manner, much like the growth rings of a tree trunk. The lamellae provide strength and stability to the bone, as well as allow the bone to withstand mechanical stress. Within these lamellae, there are spaces called lacunae that house bone cells called osteocytes. The osteocytes communicate with one another through tiny channels called canaliculi. The osteon as a whole functions to provide support, maintain bone health, and allow for the efficient exchange of nutrients and waste products.
In tree trunks, growth rings are formed due to the seasonal changes in growth. The pattern of the rings can provide information about the age of the tree and the environmental conditions experienced during its lifetime. While the overall appearance of concentric rings is similar, the primary purpose and composition of tree growth rings and osteons differ significantly.
In conclusion, it is true that the osteon's structure in compact bone resembles the growth rings of a tree trunk, as both share the feature of concentric layers or rings. However, their functions and compositions differ, with osteons providing strength and support to bones and growth rings representing the seasonal growth of trees.

5. List and define the transport properties that involve elimination of concentration differentials .
Answers
The transport properties that involve the elimination of concentration differentials are Diffusion, Osmosis , Active Transport and Bulk Flow.
Diffusion is the passive movement of molecules from an area of higher concentration to an area of lower concentration. It occurs due to the random motion of particles and is driven by the concentration gradient until equilibrium is reached. Osmosis is the diffusion of water molecules across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration. It aims to equalize the concentration of solute on both sides of the membrane.
Active transport is a process that requires the expenditure of energy to move molecules or ions against their concentration gradient. It involves the use of carrier proteins embedded in the cell membrane to transport specific substances across the membrane. Bulk flow is the movement of fluids, such as blood or sap, in response to a pressure gradient. It involves the coordinated movement of a large number of molecules or ions in a particular direction.

an experiment began with 6 cells and ended 2 hours later with 96 cells. how many generations did the cells go through during the 2-hour experiment?
Answers
since there were 5 doublings (or generations) from 6 to 96 cells, the cells went through 5 generations during the 2-hour experiment.
During the 2-hour experiment, the cells went through 5 generations. This is because each cell division doubles the number of cells, so the total number of cells after n generations is \(2^n.\)
Initially, there were 6 cells, and after the first generation, there were 12 cells (6 x 2). After the second generation, there were 24 cells (12 x 2), after the third generation, there were 48 cells (24 x 2), after the fourth generation, there were 96 cells (48 x 2), which is the final number of cells at the end of the experiment.

What if the light intensity was 1000, what do you predict the ATP production percentage would be?
Answers
Main Answer:
ATP Production will not change as change in wavelength because it depends on no. of photons striking the surface means intensity of light.
Explanation:
ATP Production is depend upon intensity of light and not on wavelength of light.
No. of electrons involved in ATP Production depends on intensity of light.
If the light intensity is about 1000, then it will not positively affect ATP synthesis. Because enzymes do not function properly, it may harm photosynthesis.
What Role Does Light Play in Photosynthesis?The sunlight acts as a catalyst for the photosynthesis process and promotes the production of ATP (energy), glucose, and oxygen. The sunlight breaks the water molecule and forms the electron. This process is called photolysis of water and takes place in the thylakoid membrane. This occurs in the thylakoid membrane's Photosystem II (PS II).
Electrons move from photosystem II to photosystem I. The movement of the electron generates the proton gradient across the membrane. Due to the higher protons inside the lumen of the thylakoid, these move to the outer side, and as a result, ATP synthase makes ATP. If such a bright light shines on these complexes, the enzymes will stop working and ATP synthesis will suffer.
Hence, an increase in light intensity would have a negative impact on ATP production.

Answers
Protists, once considered diphyletic, are now classified into supergroups based on evolutionary relationships, such as Opisthokonta, and their diverse lineages are supported by DNA evidence.
Protists were once considered to be diphyletic, meaning they contained two main evolutionary lineages. However, advancements in molecular studies and DNA evidence have led to the classification of protists, fungi, animals, and plants into supergroups, which are higher taxonomic groups within the classification hierarchy.
These supergroups include the Excavata, SAR (Stramenopiles, Alveolates, and Rhizaria), Archaeplastida, Amoebozoa, Opisthokonta, and Rhizaria. Each supergroup represents a distinct lineage with unique characteristics and evolutionary history.
For example, the choanoflagellates belong to the Opisthokonta supergroup, which also includes animals and fungi. The old protist lineages, supported by DNA evidence, are diverse and span across different kingdoms, such as the Chromalveolata and Rhizaria.
The classification of protists and other organisms into monophyletic groups based on evolutionary relationships helps us understand their evolutionary history and relationships more accurately. These groups are continually refined and updated as new scientific evidence emerges, providing a clearer understanding of the diversity and evolution within the protist kingdom and other biological domains.

The question specifies two different atoms of the same element, oxygen. All the statements regarding the two atoms are correct.
What is an atom?An atom is the basic unit of matter, consisting of a nucleus at the centre, made up of positively charged protons and uncharged neutrons, surrounded by negatively charged electrons in shells or orbitals. Atoms are identified by their atomic number, which is the number of protons in their nucleus.
From the given statements in the question, both atoms A and B have the same number of protons (8), which is the atomic number of oxygen. The atomic number determines the element's identity, so both atoms are oxygen atoms.
Atoms A and B have different numbers of neutrons, making them different isotopes of oxygen. Isotopes are atoms of the same element with the same number of protons but differ in the number of neutrons.
The sum of the protons and neutrons present in the nucleus is the atomic mass of an atom. Atom A has 8 protons and 8 neutrons, so its atomic mass is 16. Atom B has 8 protons and 10 neutrons, so its atomic mass is 18.
