what does a cell do to prepare for cell division
Answer:
interphase
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.
If you find a reptile fossil buried and lithified among mud and decayed plant material, what type of depositional environment might you infer while the animal was still alive?
Answer:
The correct answer is - swamps/bog
Explanation:
Swamps or bogs are characteristically similar as they both area are known for the poor soil or muddy soil due to the quiet water conditions which is acuumulate by the precipitation mainly. These are have high peat content where mud and decaying or decomposing plant material found.
Bog or swamps are form due to the hundered years of decomposition or decys in plants and plants materials. As it stated that the reptile fossil buriiend lithified among mud and decayed plant material the environment must be bog or swamp.
. There are many diseases that affect signal transmission along neural pathways. These includemultiple sclerosis (MS), myasthenia gravis, and amyotrophic lateral sclerosis (ALS or 'LouGehrig's Disease). Often, a component of these afflictions is a malformation or degenerationof the myelin sheath. MS is a demyelinating disease, which means that the axons of neuronsare intact but the myelin sheaths are damaged. Why would loss or damage to the myelinsheath be a problem for signal transmission, even if the axon was intact
Answer:
In neurons that are enveloped by myelin sheath, the nerve stimulus or neuronal action potential is transmitted in a saltatory way, that is, this action potential jumps in the spaces not surrounded by the myelin sheath and it is in this way that it is transmits much more efficient and faster.
Explanation:
Myelin neurons are those that are covered by myelin sheaths, this sheath is formed mainly by fatty acids, these fatty acids generate an alternate isolation along the axon so that the stimulus diffuses through the bare areas where they will have ionic channels premises in order to generate the potential for action.
If this myelin sheath disappears, not only is the response slower, but it is rendered incapable because an axon that does not have ion channels to spread the signal is discovered in the external environment.
Describe how the composition and structure of the atmosphere insulates the planet and protects organism.
Answer: because of its layers
Explanation:
The atmosphere protects life on Earth from incoming ultraviolet (UV) radiation, keeps the planet warm through insulation, and prevents extremes between day and night temperatures.
What is Atmosphere?
An atmosphere is defined as the layer of gas or layers of gases that envelop a planet, and are held in place by the gravity of the planetary body where the planetary atmosphere is present when gravity is great and the temperature of the atmosphere is low.
The Earth's atmosphere extends up to 10,000 kilometers above the surface of the planet, which merges into space.
Beyond the chemical composition which is necessary for life, the composition of the atmosphere in different thermal regions produces weather patterns that in turn determine climate while the upper atmosphere and its ozone layer protect living organisms on Earth from highly harmful UV-B radiation.
Thus, the atmosphere protects life on Earth from incoming ultraviolet (UV) radiation, keeps the planet warm through insulation, and prevents extremes between day and night temperatures.

The hydrosphere(bodies of water)would cause floods and other natural disasters while the geosphere will become infertile and the landscape change (weathering).
What is a hydrosphere?The hydrosphere is the combined mass of water found on, under, and above the surface of a planet, minor planet, or natural satellite.
Although Earth's hydrosphere has been around for about 4 billion years, it continues to change in shape.
This is caused by seafloor spreading and continental drift, which rearranges the land and ocean

describe the relationship between mitosis and the other stages of the cell cycle.
girl all you gotta do is use Google..
"Actively dividing eukaryote cells pass through a series of stages known collectively as the cell cycle: two gap phases (G1 and G2); an S (for synthesis) phase, in which the genetic material is duplicated; and an M phase, in which mitosis partitions the genetic material and the cell divides."
If 35% of the bases in a region of the Drosophila genome are guanine, what percentage in that region are cytosine bases?
Answer:
The correct answer is - 35%.
Explanation:
According to the rule of Chargaff the amount of adneine is equalls to thymine and the amount of guanine is equalls to cytosine in DNA. In a double-stranded DNA Adenine pairs with Thymine and cytosine pairs with Guanine.
So, Percentage of Adenine = percentage of Thymine
and, percentage of Cytosine = percentage of guanine
we know, percentage of guanine = 35%
Thus, percentage of Cytosine will be 35% as well.

What are the limitations of uranium-238 dating? How did you overcome
its limitations?
Answer:
4
Explanation:
Answer:
Uranium 238 is only found in igneous or volcanic rocks. So no fossils can be dated directly using U 238. Because of the huge differences in the half lives of Carbon 14 and Uranium238 they cannot be used together. Carbon 14 can only be used to date fossils of a very recent age.
Explanation:
1) Bones tend to become brittle with age. A disease called osteoporosis causes bones to become less dense and as a result, bones break more easily. Osteoporosis is more common among older women, because they produce less of a hormone called estrogen, which aids in bone formation. Many doctors hypothesize that older women who take estrogen supplements will experience fewer broken bones. Part A: Describe how an experiment could be designed to test this hypothesis. Part B: What would be the outcome variable (dependent variable)?
Answer:
A) A Randomized Control Trial Experiment is done
B) Dependent Variable is Bone Mineral Density
Explanation:
Experimental Design:
Subjects (women) of the same age bracket (say 60-70) and having approximately the same baseline estrogen level, are recruited for the experiment, and randomly assigned into two groups of an equal number of subjects each; the test group and the control group.
The Test group is given a certain amount of estrogen supplements throughout the period of the study
The control group is given a placebo, identical to the supplements given to the test group, but without any medical significance.
Every other factor is held constant for both groups of subject throughout the period of the experiment.
After, the period of the study, the Bone Mineral Density is measured in the subjects. The Bone Mineral Density is a Radiographic Test that detects the amount of light the bone can absorb, and this is directly proportional to the health of bones. One with osteoporosis will have a less dense bone than one without Osteoporosis.
B) From the experimental design above, the independent variable is; presence or absence of estrogen supplements, while the outcome/dependent variable is Bone Mineral Density.
How can we justify the conservation of energy using “system/surroundings” terminology for an open, closed, and isolated system?
Answer:
Energy can not be created nor destroyed.
Explanation:
Conservation of energy refers to the statement that energy can't be created nor destroyed, it can only be transformed into another form of energy. For example, if a pendulum swing to and fro motion, the kinetic energy is converted into potential energy. A closed system can exchange energy with its surroundings and transform that energy into heat and work. Total energy of an isolated system remains constant because no energy go out from the system.
