What role does the ocean plays in climate change ?
Answer:
erosion can shape the land , for example the Grand Canyon
As a scientist working for an anti-bioterrorism task force, you are asked to evaluate some biological samples for the presence of Yersinia pestis, the organism that causes the plague. After confirming that the samples do contain Y. pestis, you instruct your team to begin sequencing the strain. Since the genome sequence of Y. pestis is already known, why would sequencing this strain be useful?
Answer:
To gather relevant knowledge about their origin and to determine if the strain has been genetically modified.
Explanation:
A researcher researching with the anti-bioterrorism working group, they are required to assess certain blood specimens only for existence of Yersinia pestis, the organisms which causes the disease.
Since verifying that perhaps the varieties showed Y. Pestis, they are instructing their group to start sequence alignment the strains. So, this is to collect specific knowledge about their origin and to assess if the strain has also been genetically modified.

Anaerobic respiration happens in muscle cells and yeast cells.
The equation describes anaerobic respiration in muscle cells.
glucose ---> lactic acid
How can you tell from the equation that this process is anaerobic?
would the answer just be no co2 is produced?
Answer:
Am I think Co 2 will not be released but rather Glucose will be released
Explanation:
This is because
C6H12O6>2C5H5OH+2Co2 + Energy
there fore glucose is produced
From the equation "glucose → lactic acid," we can infer that the process is anaerobic. One way to determine this is by the absence of carbon dioxide (CO2) in the equation.
Glucose is entirely oxidized to create carbon dioxide, water, and energy during aerobic respiration, which takes place in the presence of oxygen.
Yet, in anaerobic respiration, the lack of oxygen causes an incomplete breakdown of glucose, producing additional byproducts such lactic acid as a result.
Muscle cells have the ability to transition to anaerobic respiration in order to satisfy their energy needs when there is insufficient oxygen.
Muscle cells have the ability to engage in anaerobic respiration, which produces ATP (adenosine triphosphate), the cellular energy currency, by partly metabolizing glucose, during hard exercise or when oxygen supply is constrained.
During anaerobic respiration, lactic acid builds up in muscle cells, which can lead to exhaustion and pain.

Which of the following are features of nucleosomes? A nucleosome contains approximately 20 base pairs of DNA. The DNA in a nucleosome is wound around eight histone proteins. Between nucleosomes is a stretch of DNA called "linker DNA". A nucleosome contains 8 different types of histones. In a nucleosome, DNA is wrapped 4 times around the histone core. H1 seals off where DNA enters and leaves the nucleosome. Nucleosomes contribute to DNA packing. Nucleosomes in chromatin are arranged in straight, side-by-side chains. Nucleosomes are about 10000 Angstroms in diameter. Histones have tails that stick out and can be modified, affecting DNA expression.
Answer:
The correct answers are "The DNA in a nucleosome is wound around eight histone proteins", "Between nucleosomes is a stretch of DNA called "linker DNA", "H1 seals off where DNA enters and leaves the nucleosome", "Nucleosomes contribute to DNA packing", and "Histones have tails that stick out and can be modified, affecting DNA expression".
Explanation:
Nucleosomes are comprised of DNA and histones that in conjunction form structural units of the chromosomes. The DNA in a nucleosome is wound around eight histone proteins, which are known as the histone octamer. Between nucleosomes is a stretch of DNA called "linker DNA", which is an unwrapped DNA that can be between 10 to 50 base pairs long. H1, one of the four types of histone, seals off where DNA enters and leaves the nucleosome serving as an anchor to the complex. Nucleosomes contribute to DNA packing by wrapping the DNA and forming the structural units of the chromosomes. Histones have tails that stick out and can be modified, affecting DNA expression; which are known as "histone tails" located in the N-terminal side and where higher order structures are arranged.

Identify the remaining processes and components of the carbon cycle. organisms release CO2 atmospheric CO2 plants use CO2 combustion fossil fuels form
Answer:
Carbon dioxide (CO2) is an important component in atmosphere and Carbon cycles allows movement of carbon dioxide from the atmosphere into living things and from living things to atmosphere again.
There are four main processes included in carbon cycle that is photosynthesis, decomposition, respiration and combustion.
In respiration, living organism such as animals and humans intake oxygen and releases CO2 in atmosphere.
In the process of photosynthesis, plants take CO2 from atmosphere and convert it into oxygen (O2) in the presence of sunlight and water.
In Decompoition, the bacteria present in soil decomposes dead matter by breaking down into simpler organic or inorganic matter such as water, carbon dioxide, and mineral salt. The nutrient cycle then recycle the carbon dioxide and send back to teh atmosphere.
In combustion, the burning of fossil fuel in cars and industries releases carbon dioxide back into the atmosphere.
So, the components of carbon cycel include atmosphere, terrestial biosphere, ocean ( dissolved inorganic carbon), and sediments ( fossil fuels).

Review Map D. Predict future weather for New Orleans, LA. What weather might occur there? What is the cause of this weather? Predict the future weather for Washington, DC. What is the cause of this weather?
Answer:
Day-to-day changes in weather can influence how we feel and the way we look at ... Meteorology is the science of forecasting weather.
Answer:
1. Many fronts cause weather events such as rain, thunderstorms, gusty winds, and tornadoes. At a cold front, there may be dramatic thunderstorms. At a warm front, there may be low stratus clouds. Usually, the skies clear once the front has passed.
2. As the warm moist air rises, towering clouds often form releasing energy in the form of brief, intense rain storms with high winds and lightning. On the other hand, warm fronts will ride up and over cold air near the surface. As it rises, the air cools and the humidity condenses to form clouds and precipitation.

which of the following words best matches this definition: The process in which the best adapted organisms survive and pass on their traits, while those that are NOT well adapted do not survive.
Answer:
Survival of the fittest
Explanation:
According to the Darwin’s theory of survival, a species can survive among its peers only when it is fit enough to adapt to the natural changes and hence remain alive till its reproductive stage in order to produce fertile offspring.
Such species which survive are known as fit species while the remaining unable to cope with changing environment die out at an early stage of life.

Consumers differ from producers in that unlike producers, consumers .b. cannot make their own food.
Producers can make their own food and energy, but consumers are different. Living things that have to hunt, gather and eat their food are called consumers. Consumers have to eat to gain energy or they will die. There are four types of consumers:
omnivores, carnivores, herbivoresdecomposers.How do consumers differ from producers?The producers generate food for themselves and others; consumers do not produce anything, instead eating producers, other consumers or both. Organisms that eat only producers (i.e., plants) are called herbivores. Animals that eat only consumers (i.e., meat) are called carnivores.

DPIP was used in the photosynthesis lab to measure the
-Light dependent reactions
-Production of O2
-Light Independent reaction (a.k.a. Calvin cycle)
-Production of CO2
Answer:
Light dependent reactions
Explanation:
DPIP stands for Dichlorophenolindophenol. It is a chemical compound that is used as a redox dye.
DCPIP is blue when it is oxidized DCPIP is colorless when it is reduced.
DCPIP measures the rate of photosynthesis. The redox dye is decolorized by chemical reduction when it is exposed to light in the process of photosynthesis.
DPIP was used in the photosynthesis lab to measure the light dependent reactions.
Why element of the xylem in vascular bundle is less than the phloem?
Answer:
The element of the xylem in vascular bundle is less than the phloem because the Xylem carries water which is a raw material to manufacture the food.
Explanation:
A pair of xylem and phloem is termed to be a 'vascular bundle'.
The purpose of the Xylem tissue is to transport the water from the roots to the stems and leaves. Other compounds are also transported which are dissolved in the water. Phloem, on the other hand, helps in transporting food from leaves to other parts of the plant.
