Holes also allow more sunlight to get through to the leaves below, which maximizes sun absorption and photosynthesis. Adaptation: During the heat of the day's sunlight, most plants open stomata (pores) in their leaves to take in carbon dioxide from the air for photosynthesis, while allowing some water to escape.

DNA is copied during the S Phase of Interphase. Why do cells copy the DNA?
Answer:
During mitosis, a eukaryotic cell undergoes a carefully coordinated nuclear division that results in the formation of two genetically identical daughter cells. Then, at a critical point during interphase (called the S phase), the cell duplicates its chromosomes and ensures its systems are ready for cell division.

When it is summer in the U.S, why is it winter in South America?
Answer:
the suns on the other side of the earth at the time
Explanation:
hope it helps :)
Answer:
The Earth is tilted at an angle of about 23 degrees, which means that depending on where Earth is on its orbit, one pole will be getting more hours of light (summer) and one will be dark (winter).
Explanation:
Also, the earth is tilted on it's axis so more direct rays of sunlight hit the southern hemisphere making it summer in that hemisphere while it is winter in the northern hemisphere. Six months later, this reverses, and more direct rays hit the northern hemisphere. That's why it's summer here while it's winter there.
The earth's distance from the sun has nothing to do with it. It's all about the axial tilt.

The Go' for the reaction Citrate Isocitrate is +6.64 kJmol-1 . The Go' for the reaction Isocitrate α-Ketoglutarate is -267 kJmol-1 . Calculate the Go' for the conversion of citrate to α-ketoglutarate?
Answer:
ΔG°' for the conversion of citrate to α-ketoglutarate = - 273.64 kJmol-1
Explanation:
ΔG°' for Citrate is +6.64 kJmol-1
ΔG°' for Isocitrate is -267 kJmol-1
ΔG°' for the conversion of citrate to α-ketoglutarate = ΔG°' for product - ΔG°' for reactant
ΔG°' for the conversion of citrate to α-ketoglutarate = -267 kJmol-1 - (+6.64 kJmol-1)
ΔG°' for the conversion of citrate to α-ketoglutarate = - 273.64 kJmol-1

At Weeks Bay there was a population of 200 alligators. In May of 2006 a new species of catfish was released into the Mississippi. These catfish reproduce very fast and soon become a rich food source for the alligator population. This provides the alligators with the energy needed for more successful reproduction. The following summer of 2007, 100 babies were born and a total of 40 gators died that year. However, the next year in early 2008 there was a terrible drought, causing 100 alligators to die.

Fossils can be body parts of ancient organisms, or they can be traces. Give five examples of trace fossils
Answer:
Trackways/footprints, mold and cast fossils, feeding marks, coprolites, and burrows. Trace fossils show the activity of ancient organisms rather than the body fossil itself. However, it is rather difficult to identify an organism by use of mere trace fossil, and therefore, it is less accurate.

Metabolic acidosis can occur as a side effect of taking acetazolamide because: Select one: a. bicarbonate ions are wasted when sodium is excreted into the urine, leaving behind acidic metabolic waste products that need to be neutralized. b. chloride ions are wasted when sodium is excreted into the urine, leaving behind acidic metabolic waste products that need to be neutralized. c. bicarbonate ions are wasted when sodium is reabsorbed into the tubule as it attracts hydrogen ions. d. chloride ions are wasted when sodium is reabsorbed into the tubule as it attracts hydrogen ions.
Answer:
a. bicarbonate ions are wasted when sodium is excreted into the urine, leaving behind acidic metabolic waste products that need to be neutralized.
Explanation:
Metabolic acidosis is an electrolyte disorder characterized by a pH of less than 7.40 and low bicarbonate (HCO3) levels in the blood. This disease may be due to 1-an increasing acid production, 2-loss of HCO3 (which acts as an acid buffer agent), and 3- by a decreasing ability of the kidneys to maintain normal acid levels. The kidneys contribute to maintaining the acid–base balance by excreting hydrogen ions (H+) into the urine and absorbing HCO3 from the urine. In metabolic acidosis, kidneys are unable to remove enough acid and conserve sodium ions (Na+), which is normally done by excreting ammonia in the urine.
As a glacier moves across the land, it pushes soil and rocks in front of it and to the sides of it. What are the hills resulting from this soil called?
Answer: They are called Moraines
Explanation: A glacier is a large body of ice originating from land that constantly moves slowly over land. It occurs in almost all parts of the world and makes up about 3/4 of fresh water all over the world.
Glaciers constantly move on land and they do this under their own weight.
As a glacier moves across land, it pushes soil and rocks in front of it and to the sides of it.
The resulting hill formed as a result of this soil movement is called a Moraine.
A moraine is sometimes referred to as a glacial till. It is an accumulation of materials (usually soil and rock) left behind by a moving glacier.

What is one of the biomolecules for which nitrogen is needed (hint: they help build muscles)?
One of the biomolecules for which nitrogen is needed and that build muscles are the proteins, and the nitrogen is also found in the DNA and RNA that are present in the cells.
What is the significance of the nitrogen in the protein?Proteins play many important roles in the body, including building and repairing tissues, and nitrogen is a critical component of proteins, as it is incorporated into the molecule as a part of the amino acids. Without nitrogen, proteins would not be able to form and perform their many important functions so a diet that is rich in protein is important for athletes and bodybuilders to build and repair muscle tissue.
As a result, of the biomolecules for which nitrogen is needed and that build muscles are the proteins, and the nitrogen is also found in the DNA and RNA that are present in the cells.

How does diversity in traits arise over generations? How can we determine the probability that an organism's expressed version of a trait will be passed on to its offspring?
Answer:
Diversity in traits arise over generations through mutation which cause evolution and speciation. We can determine the probability that an organism's expressed version of a trait will be passed onto its offspring through Hardy-Weinberg equilibrium. Hardy-Weinberg equilibrium helps us understand and know genotype and allele frequencies.
Through mutation, which leads to evolution and speciation, diversity in features develops over generations.
What is diversity?The variety of human distinctions that make up diversity includes, but is not limited to, racial or ethnic origin, gender, gender orientation, age, socioeconomic class, physical ability or traits, and political ideas.
Over generations, diversity in traits emerges through mutation, which causes evolution and speciation.
We can calculate the probability that an organism's expressed version of a trait will be passed on to its offspring using the Hardy-Weinberg equilibrium.
The Hardy-Weinberg equilibrium is used to explain genotype and allele frequencies.
Thus, this way, we can determine the probability that an organism's expressed version of a trait will be passed on to its offspring.

When a person is suddenly cut by a sharp object, a nervous impulse is sent along a sensory neuron to the spinal cord. The impulse is immediately transmitted through motor neurons to produce a response. Which of the following correctly identifies and describes this response?
A.It is a leamed response that does not occur in infants and small children
B. It is a reflex response that causes various muscles to contract in order to move away from the object.
C.It is a conditioned response that occurs only to prevent injury!
D. It is a voluntary response that is initiated only after the impulse has been caried to the relevant area of the brain.
Answer:
B. It is a reflex response that causes various muscles to contract in order to move away from the object.
Explanation:
I just took the Test
It is a reflex response that causes various muscles to contract in order to move away from the object. Therefore, option (B) is correct.
What is reflex response?A reflex response is an automatic, involuntary response to a stimulus that does not involve the conscious part of the brain. In this case, the reflex response causes various muscles to contract in order to move away from the sharp object, which helps to minimize further injury. Reflexes are a protective mechanism that can operate without the need for conscious control or decision making.
The reflex response described in this scenario is not a learned response, a conditioned response, or a voluntary response. It is an innate, automatic response that occurs in response to a specific stimulus, and it occurs in both infants and adults.
