Answer:
Explanation:
Punnet square is a square diagram used to predict the genotypes of the offspring of a particular cross or breeding experiment.
It represent 4 offsprings of the cross between two parents. Each punnet contain the alleles in the right combination and proportion.
Punnet square is use to determine the percentages of different genotypes present in the offspring of two parents and to determine missing alleles in a cross.
it can also be used to predict the percentages of phenotypes in the offspring usually from a parents with known genotypes.

7. In which direction does water move through a plant?
A. Upward from the roots
B. Sideways through the leaves
C. Downward from the leaves
Answer:
A. Upward from the Roots
Answer:
The water Moves through a plant UPWARD FROM THE ROOTS.
Explanation:
When we water the plant, we water from the root and the water goes up in the plant and that's how the every part of the plant is fully watered.
A mutation is least likely to affect a cell when the mutation --
A mutation is least likely to affect a cell when the mutation is silent in nature or is not associated with an exon, it is least likely to affect a cell. Any mutation that happens to the introns does not affect the cell's function.
What is the function of cells and mutation?As genetic materials, nucleic acids encode information about the cell's structure and function, its proteins, receptors, and so on. The mRNA that is formed from the gene has roles in the formation of the receptor, the enzymes, etc., so if any mutation happens to the gene that is in the coding region, then it can show its impact, but if the mutation is of the silent type, then it has no impact on the cell.
Hence, when a mutation is silent in nature or is not associated with an exon, it is least likely to affect a cell. Any mutation that happens to the introns does not affect the cell's function.

Two parts of the food chain are described below:
Part #1: These organisms are the ending of the food chain.
Part #2: This passes energy to plants and animals.
Which statement is true about these two parts of the food chain?
A) Part 1 are consumers, Part 2 is the sun
B) Part 1 are consumers, Part 2 are producers
C) Part 1 are producers, Part 2 is the sun
D) Part 1 are producers, Part 2 are consumers
(DONT ADD ANY LINKS)
The correct statement is B) Part 1 are consumers, Part 2 are producers.
What are the two parts of food chain?Part 1 of the food chain describes organisms that are the end of the food chain, which would typically be consumers or animals that feed on other organisms, including plants and other animals.
Part 2 of the food chain refers to something that passes energy to plants and animals. This is typically the sun, which provides energy through photosynthesis to producers, or plants, that convert light energy into chemical energy stored in food. Producers form the base of the food chain, providing energy to all other organisms in the ecosystem through the food they produce.

prokaryotic cells have a single circular chromosome and a defined nucleus? true or false?
Answer:
False, it lacks a defined nucleus.
Explanation: By definition, prokaryotes lack a membrane-bound nucleus to hold their chromosomes. Prokaryotes generally have a single circular chromosome that occupies a region of the cytoplasm called a nucleoid. They also may contain small rings of double-stranded extra-chromosomal DNA called plasmids.
Answer:
False
Explanation:
Prokaryotic cells don't have a nucleus, they have a nucleoid region

Usable fresh surface water is relatively scarce. To many people, streams and lakes are the most visible part of the water cycle. Not only do they supply the human population, animals, and plants with the freshwater they need to survive, but they are great places for people to have fun.
Answer:
True.
Explanation:
Usable fresh surface water is scarce. Freshwater is not in excess on our planet. We can find it on lakes, lagoons, rivers, and swamps, but it is only 3% of the totality of Earth's water. The importance of this water is that it is the one that is suitable for humans, a large number of plants, and animals. This is why there are different methods to store and distribute fresh water amongst all the population and places that need it. Besides, the places where freshwater is, are great for activities, such as swimming, sailing, rafting, diving, fishing, etc.
Since freshwater is scarce and has so many uses, we must take care of it.

The Rock Cycle is happening all the time on Earth.
Some processes of the Rock Cycle take a long time.
O All rocks were once Metamorphic Rocks.
O Most rocks on Earth are Igneous Rocks.
Answer:All rock were once metamorphic rocks
Explanation:
Melted rock deep inside Earth forms igneous rocks. Sand, silt, plant and animal skeletons make sedimentary rocks. Heat and pressure underground convert rocks into metamorphic rocks. Therefore, option (C) is correct.
What is rock cycle?The rock cycle is a web of processes that outlines how each of the three major rock types—igneous, metamorphic, and sedimentary—form and break down based on the various applications of heat and pressure over the course of time. Igneous rocks are rocks that are formed by volcanic eruptions, while metamorphic rocks are formed when heat and pressure are applied to preexisting rocks. Shale, a type of sedimentary rock, can be transformed into slate with the use of heat and pressure, for instance.
The rock cycle is an important component of our dynamic Earth because it allows rocks to shift from one type of rock to another based on their location and circumstances. It recycles rocks to build new structures when plate tectonics changes the Earth's surface.
