what causes dominant traits to be dominant?

Answers

Answer:

Dominant refers to the relationship between two versions of a gene. Individuals receive two versions of each gene, known as alleles, from each parent. If the alleles of a gene are different, one allele will be expressed; it is the dominant gene. The effect of the other allele, called recessive, is masked.

BRAINLIEST+15 PTS-What does it mean when a plant is "pure for its trait'?

Answers

Answer:

Non-N-fixing plants usually benefit from reduced competition in mixed stands compared to pure stands and attain higher biomass and N content per plant

Explanation:

a plant that has a pure trait is homozygous. homozygous traits are either a combination of two dominant alleles or the two recessive alleles. a hybrid would be the opposite, consisting of dominant and recessive alleles, therefore making it unpure (lol sorry) and hybrid.

Which two materials form igneous rocks upon cooling?

A lava and crystals
B magma and lava
C crystals and intrusive rocks
D intrusive rocks and sediment from rocks

Answers

Answer: B) magma and lava

Explanation:

Answer: Hope this helps you

B

Explanation:

A: Lava is one material, however the igneous rock forms crystals while cooling so it is not A.

B: Yes, it may be B since magma and lava are the two materials that form igneous rock, but let's look at the other answer thought.

C: The rock forms crystals, and an intrusive rock is a king of igneous rock so it can't be c.

D: Igneous rocks can be an intrusive rock which isn't a material that makes it. Plus, sediment from rocks form sedimentary rocks completely removing D from thought as it is completely absurd.

What is faulting?

The movement of water, nutrients, and sediments through landscapes is facilitated by river systems. When tectonic plates collide, the Earth's crust vibrates, resulting in an earthquake. Animals and plants that are living contribute significantly to the environment in which they live.

Crop rotation and cover crops are examples of practices that aid in preserving soil fertility and reducing soil erosion. The terms "faulting" and "folding" describe the tectonic forces that cause rock strata to distort, resulting in structures like mountain ranges.

When magma and ash are ejected from the Earth's crust, volcanoes are generated, and over time, they can produce new landforms. When rivers or other bodies of water overrun their banks, flooding occurs, which can harm infrastructure and force the eviction of residents.

Therefore, faulting and folding describe the tectonic forces that cause rock strata to distort, resulting in structures like mountain ranges.
