Note on chemical communication in insects in general
Answer:
Chemical communication plays an important part in the lives of insects, and particularly in lives of those that live in groups or social organizations.

Which of the following statements is NOT TRUE about photosynthesis and cellular respiration? (B.9B)
Question 19 options:
Both processes require energy
Both processes occur in the mitochondria
The chemical equations for the processes are opposite of each other.
Photosynthesis occurs in plants; cellular respiration occurs in plants and animals.
Answer:
Both processes require energy cuz respiration produces energy
Explanation:
The statement that is not true is that both processes occur in mitochondria as photosynthesis happens in chloroplasts. So the correct option is B.
What is cellular respiration in plants?While oxygen is needed for plant respiration, carbon dioxide is also released during the process. Plants, unlike people and other animals, don't have any specific structures for the exchange of gases, but they do have stomata (found in leaves) and lenticels (found in stems) that play a part in it. Compared to people and animals, leaves, stems, and plant roots respire slowly.
Respiration is distinct from breathing. Breathing is a phase in respiration that is completed by both humans and animals. Plants breathe differently through a process called cellular respiration, which they engage in throughout their whole existence since the plant cell needs the energy to survive.
Plants produce glucose molecules during this process of cellular respiration by using photosynthesis to absorb solar energy and transform it into glucose. Several real-world experiments show that plants can breathe. To provide their cells the energy they need to function and stay alive, all plants breathe.
Therefore the correct option is B.

What do you think interphase is? What might the cell be doing in this phase? Think about the prefix "inter". Write your best definition - it's ok if you're not sure, just try your best!
Answer:
Interphase is the 'daily living' or metabolic phase of the cell, in which the cell obtains nutrients and metabolizes them, grows, replicates its DNA in preparation for mitosis, and conducts other "normal" cell functions. Interphase was formerly called the resting phase.
A cell spends most of its time in what is called interphase, and during this time it grows, replicates its chromosomes, and prepares for cell division. The cell then leaves interphase, undergoes mitosis, and completes its division
Interphase is the part of time which mostly the cell utilises for its functionality.

Organism X and Y live in the same environment. Organism X contracts a bacterial infection that causes its body temperature to rise to 60°C. How will this change in temperature affect enzyme activity in both organisms?
It will decrease enzyme activity in both organism X and organism Y.
It will increase enzyme activity in organism X and decrease enzyme activity in organism Y.
An increase in temperature above the optimal range will increase the reaction rate.
An increase in temperature will denature the enzyme causing a reduction in the reaction rate.

Scott suffers from narcolepsy. He suddenly collapses in sleep at random moments, but his daughter, Tricia, is always there to help him. How might Scott's
narcolepsy affect Tricia?
a. Narcolepsy is thought to be hereditary, so Tricia has the potential to suffer from narcolepsy as well.
b. Narcolepsy is thought to be a learned behavior, so Tricia may learn narcolepsy from her father.
c Narcolepsy is thought to be contagious through a particular pathogen, so Tricia might be exposed to that same pathogen and become narcoleptic.
d. Narcolepsy will in no way affect Tricia, other than the help she will need to provide for her father.
Answer:
D
Explanation:
Narcolepsy has no pattern of inheritance.
Narcolepsy is thought to be a learned behavior, so Tricia may learn narcolepsy from her father. Thus option D is correct.
What is narcolepsy ?Narcolepsy is a type of sleeping disorder is characterized by severe and persistent daytime sleepiness which can cause impairments in school, work, and social settings.
Narcolepsy affects hundreds of thousands of Americans both children and adults, the symptoms include excessive daytime sleepiness (EDS), where the brain is unable to regulate wakefulness and sleep.
Other symptoms are rapid eye movement (REM) sleep, this sleep irregularly begins within minutes after falling asleep.
It can be up two types Types such as narcolepsy type 1 (NT1) and type 2 (NT2); NT1 is associated with cataplexy, which means sudden loss of muscle tone.
NT1 can be diagnosed with the low levels of hypocretin-1; NT2 was otherwise known as narcolepsy without cataplexy do not have cataplexy or low levels of hypocretin-1.

How does the friction affect the total time a pendulum is in motion? And what could cause this friction in the real world?
Answer:
Without friction, the equation of motion for a pendulum of length L is,
md2θdt2+mgsin(θ)L=0.
Or for small oscillations, (i.e., sin(θ)≈θ),
md2θdt2+mgθL=0.
Assuming an initial angle θ0 and a pendulum that starts at rest, the solution to this differential equation is,
θ(t)=θ0cos(gL−−√t).
Frictional force adds an additional damping term into the equation of motion,
md2θdt2+λdθdt+mgθL=0,
where λ is a coefficient of kinetic friction.
Assuming an initial angle θ0 and a pendulum that starts at rest, the solution to the damped differential equation is,
θ(t)=θ0e−12λmtcos((gL−λ24m2−−−−−−−−√)t).
(Note: If you would like to consider closed form solutions for large angles, I would recommend consulting the mathematics section. The solutions to that problem are called elliptic integrals of the first kind.)
Friction decreases the total time that a pendulum is in motion.
If we consider a pendulum in motion, in accordance with Newton's law, the pendulum will continue moving unless it is acted upon by an external force.
In the case of the pendulum, the external force that acts on it is the air resistance or friction. As a result of this friction, the pendulum will eventually come to a stop.
In the real world, the surface of objects cause friction which causes moving objects to stop.

Which pH indicates a basic solution?

12
Answer:
7
A pH value greater than 7 indicates a basic solution. The more the pH value exceeds 7, the more basic is the solution.
7 is the answer.
If the pH is 1, that means the substance is sour or acidic.
If it has a pH of 5, then it is not that acidic.
If something has a pH of 12, then it is almost completely basic.
If something has a pH of 7, then it is basic.

Compare geologic time with the geologic column . (Earth science )
Answer:
The geologic time scale (GTS) is a system of chronological dating that classifies geological strata (stratigraphy) in time. It is used by geologists, paleontologists, and other Earth scientists to describe the timing and relationships of events in geologic history. The time scale was developed through the study and observation of layers of rock and relationships as well as the times when different organisms appeared, evolved and became extinct through the study of fossilized remains and imprints. The table of geologic time spans, presented here, agrees with the nomenclature, dates and standard color codes set forth by the International Commission on Stratigraphy (ICS).
Explanation:
Thyroid hormone receptor (TR) regulates growth, development, and differentiation of mammals. TR contains both a domain that binds to T3, the thyroid hormone, and a separate domain that binds to DNA. Which of the following BEST explains how TR signals?
A. T3 binds to TR at the cell membrane, which then releases second messengers to regulate gene expression.
B. T3 binds to DNA at the cell membrane, which then releases second messengers to regulate gene expression.
C. T3 diffuses through the cell membrane to bind to TR, which then binds to DNA to regulate gene expression.
D. T3 diffuses through the cell membrane to bind to DNA, which then binds to TR to regulate gene expression.
Answer:
C. T3 diffuses across the cell membrane, attaches to Tr, and then binds to DNA to control gene expression.
Explanation: Thyroid hormone, as a ligand, diffuses across the plasma membrane, then searches for the nucleus TR (Thyroid receptor and RxR aie heterochimeric bind to DNA).
When Thyroid Hormone binds to the A domain of T3, Corepressor Proteins are removed, which stimulates gene transcription.
