Answer:
As the mass of the chest increases, more force is required to pull it.
Explanation:
Mass is a measure of the inertia of a body. Inertia means reluctance towards motion. A heavier object has a greater degree of inertia than a lighter object.
Hence, the student will notice that more force is required to move a heavier chest of books than a lighter one.
Therefore, as the mass of the chest increases, more force is required to pull it.

In multicellular organisms, cell growth and division is very controlled. Some cells like muscle and _______ cells stop dividing after maturity. Other cells like ______ and blood cells grow and divide rapidly through life. _______ are proteins that regulate the timing of the cell cycle, "telling" the cell when to divide. If cells stop responding to regulation, uncontrolled cell growth can lead to ______.
The growth and development of an organism are dependent on the control and coordinated activities of the cells, tissues, and organs.
The correct blanks for the given paragraph are:
In multicellular organisms, cell growth and division are very controlled. Some cells like muscle and nerve cells stop dividing after maturity. Other cells like Skin and blood cells grow and divide rapidly through life. Cyclins are proteins that regulate the timing of the cell cycle, "telling" the cell when to divide. If cells stop responding to regulation, uncontrolled cell growth can lead to cancer.
The statements can be explained as:
The muscle and nerve cells stop dividing after maturity. The nerve cells lack centrioles, which play a crucial role in the division of cells. Thus, the nerve and muscle cells do not divide. The skin and blood cells divide continuously and throughout life. The cells when are damaged or dead, these cells replace them. Cyclins are the proteins, which regulate and activate the cell cycle by binding with the cyclin-dependent kinases.Cancer is repetitive and uncontrolled cell growth. It can be caused due to failure of regulation of cell cycle or any carcinogen exposure.
Therefore, the correct answers are nerve, skin, cyclin, and cancer.

A: Amino acid sequence
B: Dietary preferences
C: Habitat requirements
D: Social group interactions
Answer:
A
Explanation:
Studying amino acid sequences would provide the best evidence that two organisms share a common ancestor.
Amino acid sequence is a series of bases with different letters usually four(A T C G or U) this letter contains information of an individual when translated.
The amino acid sequence of 2 or more individuals can be compare to each other through the process called Blasting using a tool called Blast
Blast generates alignments or similarities between a amino acid or protein sequence.For organisms that are phylogenetically close i.e related by an ancestor, there will be similarities between their DNA sequences when compared. The amino acid sequence of an individual contains the information of the individual and it is unique for each individual.
Hence, amino acids sequence provides the best evidence of organisms sharing a common ancestor.

What is an advantage to SMRs?
Select all that apply.
less atmospheric emissions
use fusion instead of fission
reduced cost
reduced construction time
Answer:
PLEASE MARK ME THE BRANIEST THANK YOU :)
Explanation:
The next decades are crucially important to putting the world on a path of reduced greenhouse gas emissions.
By the end of the century, demand for energy will have tripled under the combined pressure of population growth, increased urbanization and expanding access to electricity in developing countries. The fossil fuels that shaped 19th and 20th century civilization can only be relied on at the cost of greenhouse gases and pollution.
A new large-scale, sustainable and carbon-free form of energy is urgently needed. The following advantages make fusion worth pursuing.
Abundant energy: Fusing atoms together in a controlled way releases nearly four million times more energy than a chemical reaction such as the burning of coal, oil or gas and four times as much as nuclear fission reactions (at equal mass). Fusion has the potential to provide the kind of baseload energy needed to provide electricity to our cities and our industries.
Sustainability: Fusion fuels are widely available and nearly inexhaustible. Deuterium can be distilled from all forms of water, while tritium will be produced during the fusion reaction as fusion neutrons interact with lithium. (Terrestrial reserves of lithium would permit the operation of fusion power plants for more than 1,000 years, while sea-based reserves of lithium would fulfil needs for millions of years.)
No CO₂: Fusion doesn't emit harmful toxins like carbon dioxide or other greenhouse gases into the atmosphere. Its major by-product is helium: an inert, non-toxic gas.
No long-lived radioactive waste: Nuclear fusion reactors produce no high activity, long-lived nuclear waste. The activation of components in a fusion reactor is low enough for the materials to be recycled or reused within 100 years.
Limited risk of proliferation: Fusion doesn't employ fissile materials like uranium and plutonium. (Radioactive tritium is neither a fissile nor a fissionable material.) There are no enriched materials in a fusion reactor like ITER that could be exploited to make nuclear weapons.

A student poured a solution of bromothymol blue indicator into three test tubes. Then he placed an aquatic plant in two of the test tubes, as shown below. He placed a stopper on each test tube and placed them all in the dark for 24 hours. Bromothymol blue turns from blue to yellow in the presence of CO2
Predict what will happen to the test tubes in Figure 9–9 after 24 hours in the dark.
In the dark the aquatic plant won't do photosynthesis. Instead it will do cellular respiration in which it will produce CO2. Therefore after 24 hours of letting the plant in the dark introducing Bromothymol in the solution will cause it to turn yellow.

What is the niche of the shark whales?
Answer:
The whale sharks niche in the environment is essentially population control. The whale shark spends all day eating and without it the populations of krill and plankton would increase by a large amount.
Explanation:
Whale sharks have a broad distribution in tropical and warm temperate seas, usually between latitudes 30°N and 35°S. They are known to inhabit both deep and shallow coastal waters and the lagoons of coral atolls and reefs. Australia is one of the most reliable locations to find whale sharks. It is very difficult to conduct research on the shark's role in the ecosystem so scientists aren't sure what would happen if sharks became extinct. ... If the whale shark becomes extinct, there might be an increase in plankton. However, plankton are also eaten by several species of whale. Whale sharks are one of the most amazing animals in the world — and while they may be sharks, they're also one of the most gentle fish in the sea. In fact, whale sharks are so gentle, they're completely safe to swim around. Our Whale Shark Encounter tour gives you the opportunity to do just that.

One current ethical issue in marine science is the use of genetically modified organisms (GMOs) in aquaculture.
What are genetically modified organisms?Genetically modified organisms (GMOs) are living organisms whose genetic material has been artificially altered in a laboratory using genetic engineering techniques.Here are two perspectives supporting each side of the issue:
Perspective 1: According to a report by the World Health Organization (WHO), GMOs have the potential to reduce the environmental impact of aquaculture by decreasing the need for wild fish as feed, reducing the use of antibiotics, and decreasing the risk of disease outbreaks.
Perspective 2: Opponents of GMOs in aquaculture argue that they pose a significant risk to wild fish populations and the environment. According to the Ocean Conservancy, GMO fish can escape from fish farms and breed with wild fish, potentially altering the genetic makeup of natural populations and harming biodiversity.
Therefore, use of GMO's is profitable as well as hazardous for the environment.
