Answer:
Mitosis is used to produce daughter cells that are genetically identical to the parent cells. The cell copies - or 'replicates' - its chromosomes, and then splits the copied chromosomes equally to make sure that each daughter cell has a full set.

U1 A genetic change that occurs in a body cell of a
mouse will not contribute to the evolution of the
species because
(1) body cell mutations will cause the cell to die
before it reproduces
(2) the evolution of a species can result from
changes in reproductive cells, not body cells
(3) random changes are repaired by enzymes
before they are passed on to offspring
(4) the evolution of a species is caused by natural
selection, not genetic variation

Which is a layer of sedimentary rock that forms from calcium carbonate in the deep ocean?
Salt
Limestone
Sandstone
Shale
Answers
Answer:
Limestone
Explanation:
Limestone is made up of carbonate minerals, such as calcite. The shells and skeletons of ocean organisms are formed of these minerals. When the organisms die, the shells and skeletons settle on the ocean floor as layers of sediment. Over time, the layers become buried, pressed together, and cemented to form limestone.

What will finding evidence of microbial life in another world teach us about life in general?
Answers
Answer:
Explanation:
There are many things it would teach us. First, it would teach us that we are not alone in the universe. Secondly, it will teach us that there is life that can survive in extremely harsh environments. This will also allow us to examine and understand the biological mechanisms that allow these microbes to survive in these environments. This alone can open up hundreds of doors in science, allowing us to develop new technology, theories, fields etc. There is so much that we can learn about life in general from a single living alien microbe.

Applying Concepts Your friend is playing a song on a piano. Whenever your friend hits a certain key, the lamp on top of the piano rattles. Explain why the lamp rattles.
Answers
Answer:
The lamp rattles because close resonant frequency.
Explanation:
The phenomenon of increased amplitude is known as resonance when the frequency of a periodically applied force is equal to or close to the natural frequency of the system it affects. When a resonant frequency oscillating force is applied to a dynamic system, the system oscillates with greater amplitude than when the same force is applied at non-resonant frequencies.
Resonant frequencies or resonance frequencies of the system are frequencies when the response amplitude is at a relative maximum. Due to the storage of vibrational energy, small periodic stresses at a resonance frequency of the system can cause significant amplitude oscillations in the system.
Thereforee, the lamp rattles because close resonant frequency.

Describe TWO environmental consequences, other than those related to the loss of boreal forest habitat, that result from the extraction of bitumen or the transportation of synthetic oil to customers.
Answers
Answer: The greenhouse gas emissions from the extraction of bitumen and the use of large quantities of water.
Explanation:
Bitumen is a natural flammable organic matter formed from kerogen in the process of petroleum generation, which is soluble in carbon disulfide. Asphalt and mineral wax are examples of hydrocarbons which are part of bitumen. Conventional oil is extracted by wells while oil sands deposits are extracted using surface mining sectioning techniques, or are flowed to wells by in situ techniques that reduce bitumen viscosity by steam and/or solvents. So, unlike crude oil extracted in oil wells, bitumen requires an open-pit mining operation, in which large tracts are washed with a mixture of water and chemicals to separate the bitumen from a mixture of sand and clay.
Two consequences of this practice are:
The greenhouse gas emissions from the extraction of bitumen are larger than the extraction of conventional oil. The emissions produced contribute to enhance the greenhouse effect and cause global warming. The greenhouse effect occurs when certain gases retain part of the energy emitted by the earth's soil when heated by the sun's radiation. This phenomenon occurs naturally, and thanks to it, the average temperature of the Earth is about 14º C (57.2 °F). The problem occurs when these greenhouse gases increase in the atmosphere and the amount of energy that is not released into space also increases and, with it, the Earth's temperature. The extraction of bitumen from oil sands requires the use of large quantities of water, and even though water used here can be recycled, only a small amounts is returned to the natural cycle. Also, spills from the transportation of the oil could damage soils and waterways, increasing water pollution. This toxic water could get into surface.Can someone help me if this is correct

As cattle, horses, and other livestock graze in a field, their movements stir up various insects. As the insects are stirred up, egrets follow the livestock to catch and eat the insects, leaving the livestock unaffected. Which of the following best describes the relationship between the egrets and the livestock?
Parasitism
Commensalism
Competition
Mutualism
Answers
Answer:
Commensalism
Explanation:
Commensalism means that two species interact; one of them benefits from the other while that other one is neither benefited nor harmed. This explains the relationship between the livestock and egrets.
Hope this helps :)
definition: an association between two organisms in which one benefits and the other derives neither benefit nor harm.
the egrets benefit by eating the insects while the livestock are not affected
What leads to the changes in shape of the active site when pH changes?
A. more H+ interfere with the amino acid bonds
B. the OH- ions break apart the amino acids
Answers
Answer:
A. more H+ interfere with the amino acid bonds
Explanation:
Enzymes are also sensitive to pH. Changing the pH of its surroundings will also change the shape of the active site of an enzyme.
This contributes to the folding of the enzyme molecule, its shape, and the shape of the active site. Changing the pH will affect the charges on the amino acid molecules.
Answer: A. more H+ interfere with the amino acid bonds
