All cells formed from pre-existing cells
false
true
Answer:
TRUE is the answer.Explanation:
This is because "All cells form from pre-existing cells" is part of the cell theory.A German doctor, Rudolf Virchow found out about this phenomenon and proposed this fact to other scientists.When it was proved to be true, it was made to be a part of the cell theory.So, consequently, the answer would be true.The answer is True.Hope this helped,

Wind and solar power!
Explanation:
the runner below has a mass of 55 kg and is moving at 3.87 m/s. what is his kinetic energy in joules
Answer:
411.86 JExplanation:
The kinetic energy of an object can be found by using the formula
[tex]k = \frac{1}{2} m {v}^{2} \\ [/tex]
m is the mass
v is the velocity
From the question we have
[tex]k = \frac{1}{2} \times 55 \times {3.87}^{2} \\ = 27.5 \times 14.9769 \\ = 411.86475[/tex]
We have the final answer as

Explain why scientists have hypothesized that modern vertebrates and cephalochaordates eveolved by paedeomophisis.
Answer:
The following section explains the description and as per the given situation.
Explanation:
Throughout the 1920s, Walter Garang proposed whether vertebrates formed from some kind of pedomorphosis simplified such as lava. Garstang mentioned whether attaining sexually mature would just have frozen several tunicates throughout their larval stages at a much more early development stage, in which they'll replicate.

Sorry if its wrong
The food color mixes more easily with the warm water than with the cold water, as the warm water has less density than the cold water, which allows the diffusion of the color in the water.
What role does food coloring play in the lives of organisms?It has numerous negative effects on the organism, including allergic reactions to certain food coloring, increased hyperactivity in children, disruption of the endocrine system, negative effects on reproduction and development in animals, and so on. Aside from that, the animals may exhibit symptoms of liver and kidney failure due to its toxicity.
Hence, the food color mixes more easily with the warm water than with the cold water, as the warm water has less density than the cold water, which allows the diffusion of the color in the water.

If Adam is walking to his car in the snow and feels himself starting to slip and fall, he is using what sensory pathway to convey this information to the level of his conscious awareness?a. posterior column pathway b. corticospinal pathway c. anterior spinothalamic tract d. lateral spinothalamic tract
Answer: A (POSTERIOR COLUMN PATHWAY)
Explanation: Corticospinal pathways are involved in motor pathway whereas others are involved in sensory. however, lateral spinothalamic pathway carry sensations like pain and temperature.
But,the posterior column and the anterior spinothalamic carries the sensation of touch.
The anterior spinothalamic pathway carries light touch while the posterior column carry deep touch and sensation.
Now from the question,fall and slip vibration and movement brings about the activation of posterior column, However,it carries information to the conscious center of the cerebrum whereas the spinothalamic pathway carries information to the thalamus in the brain.

Which statement about the relationship between interphase, the cell cycle, and mitosis is true?
A. The cell cycle and interphase make up mitosis.
B. Interphase and the cell cycle are parts of mitosis.
C. Mitosis and interphase are parts of the cell cycle.
D. Mitosis and the cell cycle are parts of interphase.
Answer: C.Mitosis and interphase are parts of the cell cycle.
Explanation:Interphase is actually the longest stage of the cell cycle. This is the point where the cell prepares itself for division. It is composed of 3 phases:
G1 phase - is when the cell starts to grow and copies its organelles.
S phase - it starts making copies of its DNA and makes a copy of its centrosome.
G2 phase - continues to grow and produces the proteins or enzymes that will be used in the process.
After the stage of interphase, the cell will enter its M phase or mitosis in the case of body cells. Mitosis is the process of cell division.
Answer:
c
Explanation:
mitosis and interphase are part of the cell cycle

Consider the contents of your stomach 1 hour after eating this meal. What, if anything, ha been digested? What, if anything, has been absorbed? Constituents What happens to_____ in the stomach? Digested or of food Absorbed? CarbohydratesFatsProteinsVitamins SucroseWater
Answer:
Proteins
Explanation:
Of all the food types, Protein has the shortest digestion process. The digestion and absorption of protein starts in the stomach where protein is converted to amino acids and other polypeptides by the enzyme pepsin and more amino acids are produced in the pancreas by the trypsin. Note that much of these amino acids are not absorbed by the body, they are excreted through the urine as uric acid.

Question 4 (1 point) If 18 grams of oxygen reacts completely with 4 grams of hydrogen, we would expect how many grams of water?
A. Less than 22 grams because some mass is lost in the reaction
B.More than 22 grams because the oxygen gains mass during the reaction
C.22 grams because mass cannot be created or destroyed
D. There is no way to tell from this information.
Answer:
C.22 grams because mass cannot be created or destroyed
Explanation:
Reaction equation:
2H₂ + O₂ → 2 H₂O
Mass of oxygen = 18g
Mass of hydrogen = 4g
The mass of water produced is 22g according to law of conservation of mass.
The law states that " in a chemical reaction, mass is always conserved"
The sum of the mass of product and reactants must always be the same.

b. Name one advantage and one disadvantage of replacing wild forestland with
cropland.
Answer:
Advantage: Having the space and land to make an economy and to grow crops
Disadvantage: Destroying animal, and wildlife habitat and reducing O2 productions from trees
Explanation:
Why?
Deforestation can eliminate many living organisms and take down trees, which produce oxygen. On the plus side, the land allows for humanity to settle in, farm and start an economy.
One advantage is having the space and land to make an economy and to grow crops. One disadvantage: Destroying animal, and wildlife habitats and reducing O2 production from trees.
What is deforestation?
Many living things can be wiped out by deforestation, which also removes trees that produce oxygen. On the bright side, the land enables human settlement, agriculture, and the emergence of an economy.
The consequences of deforestation are increases in greenhouse gas emissions, which contribute to climate change, desertification, soil erosion, fewer crops, flooding, and a myriad of issues for indigenous people.
Therefore, having the room and acreage to build a business and raise crops is one benefit. One drawback is the destruction of wildlife and animal habitats, which lowers tree O2 output.
