Answer:
D All of the above
Explanation:
Like our bones, bones in fish can provide general protection and support to their body.
(Fun fact, jellyfish do not have bones, so when they are out of the water, they loses their bell shape structure and looks more like a flat piece of jelly. But fish tends to look the same when it is in water and out of water.)
The bone is also where the muscles will attach to, which allows for movement.
(Imagine our fingers, the muscles in our fingers are attached to our bones, which allows us to do things like typing.)
Bones can also protect the fish's brain.
(Brain can be very fragile and soft, so having a hard structure around it can protect the brain. It's kind of similar to protecting the liquid egg in an egg shell.)

True
or
not?
The compact bone is hard and dense, but it is not solid; it is filled with holes and has small canals for blood vessels and nerves, which is a true fact as the compact bone is one of the dense bones present in the body.
What is the significance of compact bone?Compact bone is a dense, hard bone tissue that provides structural support and protection to the body, and it is also involved in the storage of minerals, such as calcium, which is important for the strength and density of bones. Haversian canals are present in the compact bone and contain blood vessels, nerves, and other tissues that support the bone.
Hence, compact bone is hard and dense, but it is not solid; it is filled with holes and has small canals for blood vessels and nerves, which is a true fact as the compact bone is one of the dense bones present in the body.

How important do you think technology is to agriculture? Why is it important that the agriculture industry stay current and evolve with technology? 5 sentences
Answer with Explanation:
Here's an example answer with 5 sentences.
Technology is very important to agriculture. It allows a higher crop yield and lowers the quantity of water, fertilizer and pesticides being used. The agriculture industry should stay current and evolve with technology in order to ensure a more efficient way of farming with lesser impact on the environment. This also ensures a safer growing condition for animals and plants, thereby affecting the quality of food that people eat. This makes agricultural businesses more profitable while maintaining an eco-friendly society.

If the Carbon-14 found in a mastodon tooth went through 8 half lives, how old is the tooth? To help find the answer, use 5,000 years for the half life of Carbon-14. 8,000 years old 14,000 years old 30,000 years old 40,000 years old
Answer:
The age of the mastodon tooth is about 40000 years.
Explanation:
The presence of carbon-14 decreases exponentially in time. Let consider half-life of Carbon 14 in 5000 years. If the mastodon tooth went through 8 half lives, then we estimate its age in 40000 years.
The age of the mastodon tooth is about 40000 years.
Which scientist would agree with this statement: Giraffes all had short necks originally. Individual giraffes stretched their necks for food. The "acquired" long necks from stretching were then passed on to the offspring. The giraffe population became long-necked please help I need to figure out which scientist it is
Answer:
Jean-Baptiste de Lamarck
Explanation:
His two principles were "use and disuse" and "inheritance of acquired characteristics." The latter is what the statement is referring to.
Answer:
Lamarck
In the case of a giraffe, Lamarck believed that giraffes once had short necks that got progressively longer as members of each subsequent generation stretched their necks as long as they could. In doing so, Lamarck believed that each generation would grow slightly longer necks and pass that trait onto their offspring.Jan. 16, 2018

Imagine you accidently step on a sharp object with
your bare foot.
Explain how the parts of the peripheral nervous
system work with the central nervous system to
produce a response to the stimulus
Answer: receptors in the skin stimulate sensory neurons
Sensory neurons send messages to the central nervous system
Interneurons send messages to the motor neurons in response to messages received from sensory neurons
Motor neurons cause muscles in the leg to contract and pull the foot away
Explanation:
To produce a response to the stimulus, receptors (sense organs, muscles, glands, etc.) receive stimuli from the environment and from inside your body.
How peripheral nervous system works with the CNS?To produce a response to the stimulus the central nervous system processes information, it is the information that is received from the peripheral nervous system.
After that, the central nervous system sends this processed information to the peripheral nervous system. The peripheral nervous system sends a signal to the body part that needs to respond so you can react appropriately to the stimulus.
Therefore, if you accidentally step on a sharp object with your bare foot the peripheral nervous system work with the central nervous system to produce a response to the stimulus through receptors.

What will happen to this cell?
A) it will shrink
B) nothing
C) it will explode
The cell shown in the image is placed in a solution of 0.5 M whereas the internal concentration of the cell is 0.1 M, hence the solution is hypertonic and the cell will shrink.
The correct option is A.
What is a hypertonic solution?A hypertonic solution is a solution with a higher concentration of solutes (e.g. salt, sugar, or other molecules) compared to another solution.
When a cell is placed in a hypertonic solution, water molecules will move out of the cell and into the surrounding solution, which can cause the cell to shrink or even collapse. This is because the concentration of solutes inside the cell is lower than that of the hypertonic solution, so water diffuses out of the cell in an attempt to balance the concentration on both sides of the cell membrane.

From about 4 billion years ago to about 2.5 billion years ago, oxygen gas became more common in Earth's atmosphere. Oxygen was a toxic compound to most life forms from that time period. Today, oxygen is required by all but some of the most primitive life forms. Which statement best explains how early life forms that were harmed by oxygen evolved into today's life forms that require it?
Answer:
C
Explanation:
Over time, many species gradually adapted to a more oxygen-rich environment, allowing them to survive in shallow water and on land.
From about 4 billion years ago to about 2.5 billion years ago, oxygen gas became more common in Earth's atmosphere, but the early life forms were harmed by the gas, and later those who survived passed on their genes to the next generation through evolution.
What is the significance of oxygen in evolution?Evolution is a process that explains life's ability to adapt and change over time in response to environmental conditions and the process of evolution is one of the central mechanisms driving life's diversity, but the presence of oxygen harmed early life. As life forms evolve, oxygen becomes one of their most important gases.
Hence, from about 4 billion years ago to about 2.5 billion years ago, oxygen gas became more common in Earth's atmosphere, but the early life forms were harmed by the gas, and later those who survived passed on their genes to the next generation through evolution.
