Cell Division Homework #1 Introduction to Cell Division Directions: Compare and contrast the following pairs of terms:
1. sister chromatids / centromeres:
2. mother cell / daughter cell: Identical
3. interphase/ cell division:
4. DNA / chromosome:
5. mitosis / cytokinesis:
Answer:
Sister chromatids / centromeres: When a single chromosome has been replicated in copies, each copy is called a sister chromatids.
A special part of the chromosome called the centromere holds the two sister chromatids together. A centromere is like a built-in rubber band for two sister chromosomes.
Mother cell / daughter cell: identical.
Daughter cells are genetically identical to the mother cell at the stage of production through mitosis.
On the other hand, at the stage of production through meiosis, the daughter cells are genetically different and contain only half of the genetic material of the mother cell.
Interphase / cell division: A cell spends most of its time in what is called interphase, and during this time it grows,
replicates its chromosomes, and prepare for cell division.
The cell then leaves Interphase, undergoes mitosis, and completes its division.
DNA / chromosome: Genes are segments of deoxyirbonucleic acid (DNA) that contain the code for specific protein that functions in one or more types of cell in the body
Chromosomes are structures within cells that contains a person's genes. Genes are contained in chromosomes, which are in the cell nucleus.
Mitosis / cytokinesis: Basically, mitosis is a process by which the duplicated genome in a cell is separated into halves that are identical in nature.
Cytokinesis is the process where the cytoplasm of the cell divides to form two 'daughter' cells. The result is the formation of two 'daughter cells', each having a nucleus.
Wether the apple has a taproot or a fibrous root
Answer:
taproot
Explanation:
Apple trees roots consist of a deep taproot and lateral fibrous roots. The taproot is analogous to the carrot, which is a taproot. Lateral fibrous roots can extent to more than twice the spread of the canopy of the apple tree and are influenced by soil, water availability and competition from the roots of other plants.
Answer:Tap roots.
Explanation:Because the roots are long.

Because scientists are unable to predict when and precisely where an earthquake will occur, the government has a duty to issue building codes to ensure that all structures can withstand earthquakes. Agree and disagree
Scientists are unable to predict when and where the earthquake will occur precisely, so the government has a duty to issue building codes to ensure that all the structures can withstand earthquakes. I agree with the given statement.
What is Earthquake?An earthquake is a natural disaster which happens when the two blocks of the earth suddenly slip past each other, this causes the tectonic plates to move. The surface where the blocks slip is called the fault or fault plane.
Earthquake damage the buildings and other infrastructure completely which can be fatal for the people living in that area. So, to save life of people government has the duty to issue the buildings code to ensure that all the structures can withstand earthquake.

How do coral reefs help with climate stability?
They need vast amounts of carbon dioxide for energy.
They support mangroves and seagrasses that release carbon.
They are habitats for species that build exoskeletons from carbon.
They release atmospheric carbon that organisms use to live and grow.
The coral reefs help with climate stability because they serve as homes for species that build exoskeletons from carbon.
Carbon in the form of carbon dioxide has been reported to be a major factor in the climate instability of the planet. This is because they are parts of the greenhouse gases that form a blanket layer over the atmosphere and prevent reflected sun rays from escaping back to space.
Thus, greenhouse gases cause the earth's atmosphere to warm up, a phenomenon known as global warming. The warming, in turn, leads to the unpredictability of several climatic factors.
With the majority of the species living in coral reefs helping to make use of carbon dioxide to build their exoskeleton, they are helping to reduce the concentration of the gas in the atmosphere and thereby reducing warming and erratic climatic changes.

what is the difference between camouflage and mimicry
Answer:
Camouflage would be a process of an individual or creature disguising themself with their surroundings or environment. It can be used to disguise their identity, presence, and movement. While mimicry is the act of copying or mimicking other individuals. When referring to animals though, it is the evolved resemblance of another creature and can be used for the protection of one-self. The Viceroy and Monarch butterfly is a good example of mimicry since the monarch butterfly is poisonous and the viceroy is harmless. Because of this, many creatures know not to eat monarch butterflies and would be cautious around the viceroy as well, because of the striking resemblance between the two. Hope this could help!

I need help on 3 Factor that affects population thingy. I don’t understand anything :(.
Answer:
Population growth (I think because birth rates, death rates affect populations)
Dispersion: There are three types of population dispersion are uniform dispersion, random dispersion, and clumped dispersion.
example question: "Describe the types of population dispersion, with examples, and the factors that influence them."
(I'm using this as a example to explain dispersion)
(things that affect dispersion) - Water supply, climate, shape of the land, vegetation, soils and availability of natural resources. In uniform dispersion, individuals of a population are more or less evenly distributed for example, allelopathy plants. In random dispersion, individuals are distributed randomly in the ecosystem for example, dandelions plants. Clumped dispersion is when individuals in a population are clustered together for example, pine trees. (or any forest)
Explanation:
Birth rates are a major factor because it is a continuous way for a population to grow, if you have low birth rates and high morality (Death rates) a population wont be balanced and death would largely out number the morality rate and time span of a population. That being the older population dies quickly because there is no younger populations to help them. This can lead to extinction too. Immigration is a population or group moving to the current one, it impacts population because its a very large group of new species being introduced to the current one adding numbers. This can also be bad because some immigrated species could be invasive and kill or take over the current/native species.
Example:
Algae blooms can reduce the ability of fish and other aquatic life to find food.
drag the labels to their appropriate locations on the diagram of the neurons below. use targets of group 1 to indicate the components of neurons. use targets of group 2 to indicate the locations of gated ion channels.
Neurons are cells in chauge of synapsis. a)cell body / b)myelin sheath / c)synaptic terminal / d)axon hillock / e)nucleus / f)location of voltage-gated channels / g)location of ligans-gated channels / h)axon / i)dendrite
-------------------------------
Most neurons are composed of a cell body, dendrites that are cytoplasmic extensions that receive impulses from other cells, and an axon that is a long formation capable of conducting the electrochemical signals.
Neurons transmit nervous impulses.
Every neuron forms connections with other neurons. These connections are known as synapsis.
During synapsis, when a presynaptic neuron sends information, it releases neurotransmitters. This event is done through exocytosis.
The neurotransmitter is a molecule that travels through the synaptic space forward to the other neuron.
Once it reaches the target, it binds to its receptors in the postsynaptic membrane, causing ion channels to open.
This binding produces a depolarization of the cell called an excitatory postsynaptic potential.
Once the action potential is initiated, it spreads to the rest of the membrane, depolarizing it.
When the electrical stimulus is applied to the axon's membrane, it produces depolarization by activating the sodium voltage-dependent channels all along the axon.
Besides, there is an increase in sodium permeability.
Depolarization propagates to inactivated regions adjacent to the membrane opening more sodium channels.
The fiber diameter and the conduction velocity are closely related, exhibiting a directly proportional relationship. Mielinized fibers are thick, and their conduction velocities are very fast.
The conduction velocity sharply increases in myelinated fibers. This is because of the high concentrations of sodium channels in the Ranvier nodes that are not myelinated areas, and the diameter of the axon becomes thinner.
