Gregor Mendel crossed true-breeding plants with yellow seeds (YY) and true-breeding plants with green seeds (yy) to determine what this cross would produce. What is the independent variable in Mendel's experiment?
Question 12 options:
How many tall plants resulted from Mendel's cross
How many yellow plants resulted from Mendel's cross
Color of seeds Mendel chose to cross
Height of plants Mendel chose to cross
Answers
Answer:
Color of seeds Mendel chose to cross
Explanation:
This variable does not depend on the other variables you are trying to measure, so it is independent.
In Gregor Mendel cross, the variable does not depend on the other variables you are trying to measure, so it is independent.
What is Gregor Mendel cross?Mendelian Crosses: In one of his experiments on inheritance patterns, Mendel crossed plants that were true-breeding for violet flower color with plants true-breeding for white flower color (the P generation).
Mendel first experimented with just one characteristic of a pea plant at a time. He began with flower color and cross-pollinated purple- and white-flowered parent plants. He was surprised by the results. This led to his law of segregation.
A dihybrid cross is a breeding experiment between two organisms which are identical hybrids for two traits. In other words, a dihybrid cross is a cross between two organisms, with both being heterozygous for two different traits.

why organisms need specialised cells and tissues in order to survive
Answers
the cells get oxygen and nutrients from this extracellular fluid and release waste products into it. Humans and other complex organisms have specialized systems that maintain the internal environment, keeping it steady and able to provide for the needs of the cells.
systems of specialized cells within organisms help them perform the essential functions of life, which involve chemical reactions that take place between different types of molecules, such as water, proteins, carbohydrates, lipids, and nucleic acids. All cells contain genetic information in the form of DNA molecules.
Multicellular organisms require cells to perform various functions and collaborate to maintain a balance in the system known as homeostasis. As a result, specialized structures become specialized for specific functions.
What is cell specialization?Cell specialization, also recognized as cell differentiation, is the methodology by which formulaic cells transform into specific cells that perform specific functions within the body.
Cell specialization is especially important during embryonic development.
Cell specialization allows multicellular organisms to express fewer genes in individual cells, protecting genes from mutagen damage.
Cell specialization occurs primarily during embryonic development as a result of cell signaling of cytoplasmic determinants.
Adult stem cells become specialized to various types of stem cells primarily due to gene expression regulation.
Cells in multicellular organisms must perform a variety of functions and collaborate to maintain a balance in the system known as homeostasis. As a result, specialized structures evolve to perform specific functions.
Thus, the organisms need specialized cells and tissues in order to survive.

Which term can avoid traveling through a solid, a liquid, or a gas?
Answers
The term that can avoid traveling through a solid, a liquid, or a gas is "electromagnetic radiation" or "light."
Electromagnetic radiation: Electromagnetic radiation refers to the propagation of energy in the form of waves or particles through space. It includes various types of radiation, such as visible light, radio waves, microwaves, X-rays, and gamma rays.Traveling through solids: Solids have a tightly packed arrangement of atoms or molecules, which makes it difficult for electromagnetic radiation to pass through them. The particles in solids interact with the radiation and absorb or scatter it, preventing its transmission.Traveling through liquids: Liquids have a less rigid arrangement of particles compared to solids. While some electromagnetic radiation can pass through liquids, it may be partially absorbed or scattered due to interactions with the liquid molecules.Traveling through gases: Gases have widely spaced particles, allowing electromagnetic radiation to travel more freely compared to solids and liquids. However, certain gases can still interact with specific types of radiation, such as absorbing certain wavelengths or causing scattering.Overall, electromagnetic radiation, or light, has the unique property of being able to propagate through a vacuum, which means it can travel through space where there is no matter present, as well as through various mediums, including gases, liquids, and solids.

Consider the global 'Greenhouse Effect", where thermal energy from the sun is naturally trapped by 'greenhouse gases' present within the Earth's atmosphere. A majority of heat generated from this process is then absorbed by the world's oceans, where it is sequestered and stored. What are some of the predictable consequences recently observed over the past 40-50 years with the observed rise in Global Mean Temperature, correlate with an increase in greenhouse gas emissions from burning of fossil fuels across that same period?
a. retreat of winter and summer sea ice, decreasing the amount of solar energy directly absorbed into the oceans
b. warming of deep ocean water and increased evaporation at the surface
c. warming of oceanic surface temperatures, driving the formation of more powerful hurricanes & rainstorms
d. thermal expansion of oceanic water, leading to mean global sea level rise
e. melting of Himalayan glaciers and collapse of Antarctic ice shelves into the sea
Answers
Answer: it would be C e is correct however but that’s already happened. So that wouldn’t be much of a prediction. Hope this helped :)
Explanation:
Thermal expansion of oceanic water leads to a main global sea level rise. So the correct option is D.
What is the greenhouse effect?
Because it absorbs heat in the form of infrared light from the Sun, a greenhouse gas circulates that heat throughout the atmosphere before losing it to space. Although it has a considerably smaller impact on global temperatures, greenhouse gases also speed up the pace at which the environment can collect short-wave radiation emitted by the Sun.
More heat from the Sun is being trapped in our atmosphere thanks to the accumulation of CO2 that is emitted after the combustion of fossil fuels. Human-made acts are referred to as anthropogenic actions, and the emission of CO2 is one such anthropogenic activity that adds to the current heightened greenhouse effect.
A greenhouse gas's contribution to the greenhouse effect is determined by how much energy it absorbs, how much it reflects back, and how much of it is present in the atmosphere.
Therefore the correct option is D.

Answers
Tertiary consumers in a food chain or food web are animals that obtain their nutrients and energy by feeding on other animals within the same food chain or web.
Tertiary consumers are usually at the top of the food chains in their ecosystem. They have the capacity to feed on animals that consume grasses directly (primary consumers) or even on animals that feed on other animals (secondary consumers).
Secondary consumers, on the other hand, are animals that feed on primary consumers. They, at the same time, serve as prey for tertiary consumers in the ecosystem.
Thus, an animal that has the capacity to be both a secondary and a tertiary consumer would have the capacity to feed on other animals as well as be hunted as food by other members of the ecosystem.
