in the figure, which number represents dna synthesis?
The number that represents DNA synthesis in the figure would be II.
DNA synthesis happens at the S phase in the interphase of the cell cycle, just after the G1 or cell growth phase and before the G2 or protein synthesis phase.
During the S phase, the amount of DNA in the cell doubles as replication of DNA takes place. However, the number of chromosomes remains constant.
The doubling of the amount of DNA is responsible for the sharp rise in the line that represents the amount of DNA in the figure. Thus, the region of a steep rise in the amount of DNA would represent the DNA synthesis phase.

How does this question represent the law of conservation of energy that energy cannot be created or destroyed? Consider the role of photosynthesis in your answer.
You need to put this into your own words, or else your school system will detect you copied from a source named Brainly.
Anyways, the law of conservation of energy is exactly what it says. Energy cannot be created nor destroyed. All they do is rearrange.
Now, for photosynthesis, it's an interesting thing. Photosynthesis takes the energy from the sun's light to produce sugars/carbohydrates. The sun's energy just got reused. It also uses water, which comes from the soil/ground. This simply, reuses the water. During photosynthesis, it also absorbs the carbon dioxide from the air. The carbon dioxide like everything else listed, got reused.
Meaning, energy does not leave. It endlessly works for different purposes. And as you should know, all of the water on the planet has been here since the dawn of time.
Hopefully this makes sense. Have a nice day!

red-green colorblindeness occurs more commonly in men than it does in women. using this information, which chromosome do you suppose the gene for red-green colorblindness resides on, and is the trait dominant or recessive?
Answer:
Usually the Y chromosome. It is recessive because if one Y chromosone is mutated with red-green colorblindness and the X is not, the child will have colorblindness. But, if one X chromosome has the mutation and the other X does not, they will cancel out, meaning the child will not have colorblindness.
Explain a trend or pattern you observe in the graph?
Answer:
The heavier the hummingbird, the fewer times its wing will beat per second.
Explanation:
There is a negative slope in a graph respective to the components of the x and y axis. Therefore, heavier the hummingbird -> less beats per second.

A pH of 7, [H+]=[OH] below pH 7, which of these is greater_____. Bases have a pH that is ______ than 7
Answer:
below pH 7 H+ is greater because hydrogen ions are produced only by acids in an aqueous solution and acids have a pH below 7
bases have a pH that is greater than 7.
Which process must occur for a muscle to be able to relax?
A. A nerve must initiate an action potential in the muscle fiber.
B. The amount of ATP in the neuromuscular junction must increase.
C. The concentration of calcium in the myofibril must decrease.
D. Myosin and actin must attach to each other.
Answer: C. The concentration of calcium in the myofibril must decrease.
I hope this helps.
Answer:
c
Explanation:
Relaxation occurs when stimulation of the nerve stops. Calcium is then pumped back into the sarcoplasmic reticulum breaking the link between actin and myosin. Actin and myosin return to their unbound state causing the muscle to relax.
2. How did dark matter affect the development of structures in the early universe?(1 point)
It cooled pockets of gas to form nebulae.
It became part of black holes.
It seeded the development of quasars.
It seeded the development of galaxies.
Answer:it seeded the development of galaxies
Explanation:
Dark matter affected the development of structures in the early universe as it seeded the development of galaxies.
Dark matter is simply refered to as a glue that bounds the Universe together. they are also dark matter halos are now stated to be the sites where galaxies were born. The universe as a whole ks made up of helium and hydrogen, dark matter was very essential in giving of the gravitational force needed in the gathering of elements together to form stars.Conclusively we can therefore say that Dark matter is the sit that holds the existence of galaxies.

Astrologers relate the location of the stars and planets to events in human lives. Many years ago,people classified astrology as a science. Why do modern scientists consider astrology to be a pseudoscience?
Answer:
C.
Explanation:
yes, astrology doesn't offer conclusive proof of its claims. astrologers predict the future with the location of planets and stars but they don't have a concrete theory that the location of a particular planet has an impact on human life. they believe in something called universal energy.

How do your sensory organs help you to maintain homeostasis?
Answer:
Hi
Explanation:
“Sensory cues influence homeostasis by modulating hormone secretion. ... In step 1, sensory cues change the activity of sensory neurons. In step 2, the sensory information is processed and transmitted, which leads to step 3, where neuro- or nonneuronal endocrine cells secrete hormones required in maintaining homeostasis.”

integral proteins are important to maintain the strength of the cell membrane. true of false?
Answer:
false
Explanation:
Integral proteins are one type of membrane protein. They are constantly associated with the membrane, carrying out many different functions but they do not maintain the strength of the cell membrane. The sentence is False.
-----------------------------------
Plasmatic membranes are composed of lipids and proteins.
Among the proteins, we can find integral proteins and peripheric proteins.
Integral proteins are permanently associated with the membrane.
They accomplish many different functions such as substances transport, cellular receptors, cellular adhesion, among others.
According to how they are incrusted in the lipidic bilayer, integral proteins might be,
Transmembrane proteins ⇒ span the entire membrane⇒ present in every membrane cells
Monotypic integral proteins ⇒ attached to only one of the lipidic layersIntegral proteins provide structure to the plasmatic membrane, but they do not maintain its strength.
