A plant does not grow when its apical meristem is cut. justify the statement
Answer:
Apical Meristem undergo rapid cell division ,hence is responsible for growth in height of the plant and is found on the tip of the plant. So, if apical meristem is either damaged or cut, growth can't take place and the plant will stop growing
Explanation:
Apical meristem undergo through rapid cell division, thus it is responsible for growth of height and if the meristem is cut the growth stops.
What is apical meristem?Apical meristem is defined as the region of cells responsible for the division and growth in the root and shoot tips in plants.
Apical meristems are special zones of growth present at the tips of plants and these are responsible for the growth of shoots and roots and shows primary plant body.
The main function of apical meristem is growth of plant and unlike undifferentiated plant cells, differentiated plant cells generally cannot divide and produce different types of cells.
There are mainly two types of apical meristem and these are shoot apical meristem (SAM) and root apical meristem ( RAM).
Therefore,Apical meristem undergo through rapid cell division, thus it is responsible for growth of height and if the meristem is cut the growth stops.

Which process allows a bacterium to take DNA from its environment and add it to its own genome?
Answer:
b transformation
Explanation:
In transformation, a bacterium takes up a piece of DNA floating in its environment. In transduction, DNA is accidentally moved from one bacterium to another by a virus. In conjugation, DNA is transferred between bacteria through a tube between cells.
The muscle weakness of myasthenia gravis results from loss of acetylcholine receptors in the end-plate membrane. the motor neuron action potential being too small to shock the muscle fibers. insufficient acetylcholine release from presynaptic vesicles. excessive acetylcholinesterase that destroys the neurotransmitter. All of the answers probably contribute to the muscle weakness.
Answer:
The correct answer is ''loss of acetylcholine receptors in the end-plate membrane.''
Explanation:
Myasthenia gravis represents a human autoimmune disease. The neuromuscular junction abnormalities that occur in this disease are due to antibody-mediated processes. A reduction in the number of functional acetylcholine receptors on the postsynaptic membrane was established to contribute to the physiological abnormalities of myasthenia gravis. The reduction in receptors is due to immunological alterations directed against the acetylcholine receptor. Normally, when acetylcholine binds to its receptor, it opens allowing the rapid entry of cations, especially sodium. With this, the depolarization of the postsynaptic region of the muscle fiber occurs. Although acetylcholine is normally released in myasthenia gravis, it is not capable of causing an action potential in the muscle sufficient to initiate or weaken contraction. In patients with myasthenia gravis, failure to activate muscles is responsible for myasthenic fatigue. Most patients have elevated serum titers of antireceptor antibodies, which in turn accelerate receptor degradation.

Which of the following is NOT true of enzyme activity? a. enzyme shape may change during catalysis b. the active site on an enzyme orients its substrate molecules, therby promoting interaction of their reactive parts c. all enzymes have an active site where substrates are temporarily bound d. each enzyme can catalyze a wide variety of different reactions
Answer:
D. Each enzyme can catalyze a wide variety of different reactions
Explanation:
Each enzyme can only catalyze a few, specific types of reactions.
Since enzymes and substrates are very specific to one another, enzymes cannot catalyze a wide variety of reactions.
If a substrate is not the correct one that fits in the enzyme's active site, a reaction will not occur.
So, each enzyme can only assist in a few reactions.
The correct answer is D. Each enzyme can catalyze a wide variety of different reactions

B. They allow voluntary movement.
C. They allow us to move.
D. They are connected by gap junctions.
The one that is not true regarding muscular system is that they are connected by gap junction. The correct option is D.
What is gap junction?Gap junctions are specialized intercellular connections that connect a wide variety of animal cell types.
They connect the cytoplasm of two cells directly, allowing molecules, ions, and electrical impulses to pass through a regulated gate between cells.
Location includes that the gap junctions can be found in a variety of locations throughout the body.
This includes epithelia (surface coverings of the body), nerves, cardiac (heart) muscle, and smooth muscle (such as that of the intestines). Their primary function is to coordinate the activity of neighboring cells.
Skeletal muscle cells lack gap junctions because they do not require them. Skeletal muscles are not made up of individual cells.
Thus, the correct option is D.

1.Explain what makes a scientific experiment reliable. Be sure to include at least three reasons to support your answer.
2.During research, why is it important to use peer reviewed evidence when collecting background information during a scientific investigation?
An experiment is reliable when its repetition produce always the same result. In science, peer review is fundamental because this process ensures that there is not misleading data that may lead to erroneous results.
In sciences, reliability is a term used to evaluate the quality of research. Reliability refers to the probability that an experiment or result is correct, thereby preventing and mitigating failures over time.
An experiment whose successive repetitions conduct the same result is 100% reliable.
Three examples of reliability in science: the same measurement of the size of the leg of a spider. the observation of the same behavior of birds populations on different days and at different times of the day. the same byproducts from a given chemical reaction when an experiment is repeated two or more times.
Peer review is the most widely accepted process used to validate scientific data. This process (peer review) is fundamental to facilitate the growth of scientific knowledge.
During peer review, independent scientists assess the originality, reliability, and significance of a scientific work before its publication.

Isabel's first car had a manual stick shift. After many years of driving an automatic car, she needs to use her sister's car, which also has a stick
shift. Isabel takes a few minutes to get used to shifting gears. Which memory system Is she using to recall this information?
• A. episodic memory
O B. procedural memory
• C.
semantic memory
)D.
sensory memory
Answer:
Procedural memory
Explanation:
Isabel has to recall the information about using a manual stick shift. For this reason, she is using long-term, explicit, declarative and episodic memory system.
Human memory system can be broadly classified as: sensory memory, short-term memory and long-term memory.
Long-term memory is used to recall information. If the information are about facts, events and experiences then explicit, declarative and episodic memory helps to recall all information. This will help Isabel to recall all information about driving a car with a manual stick shift and she will be able to drive her sister's car.

Which of the following statements about active transport is true?
Molecules move down the concentration gradient.
ATP is not required to move molecules through the membrane.
ATP is formed as molecules pass through protein channels.
It results in a higher concentration of molecules on one side of the membrane.
Answer:
It results in a higher concentration of molecules on one side of the membrane.
Explanation:
Active transport is the transport of molecules up the concentration gradient. This means that molecules are going from low density to high density. This is the opposite of natural diffusion. So, it requires ATP to move the molecules this way. Diffusion normally occurs to maintain homeostasis and an equal amount of concentration on both sides of a membrane. But, with active transport, since molecules are moving up the gradient, the opposite happens and the concentrations are unequal.

Show the importance of the inheritance of how steps in meiosis change chromosomes through one of these processes.
Background: Meiosis is the process used by sexually reproducing organisms and is made up of eight sub-steps or phases. During meiosis, chromosomes can be changed through crossing over and nondisjunction leading to changes in the inherited traits of offspring.
Meiosis is the process that occurs in sexually reproducing organisms in the sex cells of male and female organisms.
Variation occurs in an organism due to the process of crossing over which only occurs in meiosis in which the chromosomes between non-sister chromatids exchanged. Meiosis also causes genetic variation due to the process of recombination so in inheritance, meiosis has great importance and impact on the shape and structure of organism.
