The best definition of a true-breeding plant is one that ______.
A true-breeding plant is one that produces offspring identical to itself in terms of physical traits when self-pollinated, due to being homozygous for certain alleles.
The best definition of a true-breeding plant is one that, when it self-pollinates, will always produce offspring with the same physical traits or characteristics as the parent plant. These plants are considered to be homozygous for the traits of interest, meaning that they carry two identical alleles at their respective gene locus. Because of their genetic uniformity, true-breeding plants are fundamental in genetic research and ensure consistency in the inheritance of traits. For instance, when Gregor Mendel conducted his experiments, he used true-breeding pea plants to study how traits were passed from one generation to the next, which helped him to avoid any unexpected traits that could arise from plants that were not true breeding.

what was most likely responsible for the fact that organic molecules no longer form spontaneously on Earth?
Answer: Less ultraviolet light and more oxygen.
Explanation:
The early earth condition were different from now. There was more ultraviolet light as there was no ozone layer during the early earth conditions.
The oxygen levels at the time of early earth was also not high but after the evolution of cyanobacteria the level of oxygen rised very rapidly.
These conditions does not allow the formation of organic molecules from inorganic molecules.

Name the four major modes of prokaryotic nutrition. for each identify the energy source and carbon source
These are the four major modes of prokaryotic nutrition.
Photoautotrophs obtain their energy from the sun and their carbonsource from carbon dioxide which is use in photosynthesis to produce food.Photoheterotrophs get their energy source from sunlight and their carbon source from organic matter. They depend on photoautotrophs.Chemoautotrophs obtain their energy from Chemical compounds and Carbon from Carbon dioxide or related compoundsChemoheterotrophs also obtain their energy from Chemical compounds and carbon source from Organic compounds.What are prokaryotic?Prokaryotic are organisms that don't have nucleus or membrane bound organelles.
What is Nutrition?Nutrition refer to processes in which organism uses food to sustain life. It involve processes like anabolic and catabolic process gathering and breaking down of food particles.
Therefore, The four mode of prokaryotic nutrition are;
Photoautotrophs obtain their energy from the sun and their carbonsource from carbon dioxide which is use in photosynthesis to produce food.Photoheterotrophs get their energy source from sunlight and their carbon source from organic matter. They depend on photoautotrophs.Chemoautotrophs obtain their energy from Chemical compounds and Carbon from Carbon dioxide or related compoundsChemoheterotrophs also obtain their energy from Chemical compounds and carbon source from Organic compounds.Learn more on Prokaryotic mode of nutrition from the link below.

Besides the ability of some cancer cells to divide uncontrollably, what else could logically result in a tumor?
Other than the ability of some cancer cells to divide uncontrollably, the lack of appropriate cell death can logically result in tumor. When there is an occurrence of lack of appropriate cell death, this can lead to inappropriate tissue growth and tumor development. This is also characterized by altered mitochondrial metabolism. When there is a centrality of the dysfunction of the mitochondria in our system, there is surprisingly a wide range of major human diseases slowly becoming recognized. This brings along with it the prospect of novel therapeutic approaches to treat a multitude of unpleasant and pervasive diseases. We can therefore say that the there is a large and vital contribution of mitochondria in the maintenance of the normal cells in the body of an individual.
Which of the following is NOT one of Earth's four spheres?
1)
Mesosphere
2)
Hydrosphere
3)
Atmosphere
4)
Biosphere
the four earth spheres are atmosphere lithosphere hydrosphere and biosphere ...... therefore mesosphere is NOT part of it
The correct option would be the Mesosphere.
The earth has 4 systems, otherwise known as spheres. These include:
The atmosphere: the portion of the earth containing air.The hydrosphere: the portion that contains water.The biosphere: the portion that contains living organisms.The lithosphere: the rocky, otherwise known as the outer portion of the earthHence, the only option that is not part of the four spheres of the earth is the Mesosphere.

What is the major monosaccharide found in the body?
The major monosaccharide in the human body is glucose, which serves as the primary source of energy for cells and is crucial in the production of ATP.
Explanation:The major monosaccharide found in the human body is glucose. Monosaccharides are the simplest form of carbohydrates, and glucose is the primary source of energy for the body's cells. It is carried through the bloodstream and is used by cells to perform their functions. The liver and muscles store excess glucose in the form of glycogen, which can be converted back to glucose when needed. Glucose is also a crucial component in the production of ATP, the molecule that serves as the main energy event in the human body.

Why is it not correct to say that matthew 23 is anti-semitic?
Antisemitism is aggression to, bias, or discernment counter to the Jews. An individual who grips such points is termed as an anti-Semite. Antisemitism is usually measured to be a kind of racism.

A food allergy is the likely result of the absorption of intact _____.
Which of these actions is an example of chemical weathering
A. Freezing water widens the cracks in rocks
B. Plants roots force their way into cracks in rocks and break them
C. Oxygen in air reacts with iron content in rocks, causing them to change color
D. Strong winds peel soft rock away, leaving harder rock behind
Answer:
The correct answer is option C.
Explanation:
The erosion or the disintegrations of the building material or rock by the chemical reactions instead of a mechanical process termed as chemical weathering. Oxygen present in the air reacts with iron content present in rocks, causing them to react with oxygen in the air and form an iron oxide that can leach in rock and make it rusty looking. This change in color is completely a chemical change that is occurring. There is also the erosion of rock that takes place in this process.
Thus, the correct answer is option C.
Which division in the plant kingdom consists of plants that lack xylem and phloem?
Nonflowering vascular plants
Nonvascular plants
Flowering vascular plants
Seedless vascular plants
The correct answer is option B, Nonvascular plants
Non Vascular plants lacks true leaves, seeds, flowers and vascular tissues (which includes Xylem and Phloem). They come in the category of bryophytes which are extremely small and are in habituation of absorbing water and minerals through their hair like structure called as rhizoids (instead of roots) rather than transporting water and food through Xylem and Phloem tissues. They usually survive in moist places to compensate for the absence of vascular tissues.
