B. when the minerals in metamorphic rocks become calcified
C. by extreme temperatures and pressures
D. when the minerals in sedimentary rock react with acidic compounds in the ground

Answers

Answer: A. When magma cools and solidifies

Explanation: Igneous rocks form when magma cools and solidifies. This could occur on a volcano or on Earth’s surface, though it must be noted that all magma develops underground. Similar to lava, magma is molten rock that is underground. A way to remember how igneous rocks are formed is by remembering that the term is derived from the Latin word for fire, which can remind you of magma.

Amoebas are a group of single-celled organisms belonging to the phylum Amoebozoa. They are classified as protists, which are a diverse group of eukaryotic microorganisms that do not fit into the categories of plants, animals, or fungi.

Amoebas are characterized by their ability to move and change shape through the use of pseudopodia, which are temporary extensions of their cell membrane. These extensions allow amoebas to engulf and surround their food, typically consisting of bacteria, algae, or other small organisms.

When two plants, both tall, were crossed, they produced some offspring that were dwarves. Assuming that the height of the plant is controlled by a single gene and the allele for the tall plant is dominant, what is the genotype of the parents? A. TT and TT B. TT and Tt C. Tt and tt D. Tt and Tt

Answers

Answer:

B for plato users

Explanation:

If both plants are tall and produce some offspring that are dwarfed, it indicates that both parents must have been heterozygous for the height gene. The genotype of the parents is most likely Tt and Tt. Hence option D is correct.

What is a genotype?

A genotype is the genetic makeup of an organism, which is determined by the combination of alleles (different forms of a gene) inherited from its parents. Genes are located on chromosomes and each individual has two copies of each gene, one inherited from each parent.

The genotype of the tall plants could be either homozygous dominant (TT) or heterozygous (Tt), as both genotypes would result in a tall phenotype.

Therefore, the possible genotypes of the parents are:

Tall plant 1: TT or Tt

Tall plant 2: TT or Tt

If we assume that both plants were heterozygous (Tt), then the Punnett square for the cross would be:

   T t

T TT Tt

t Tt tt

As we can see, there is a 25% chance of producing dwarf offspring (tt) when two heterozygous plants are crossed. This result matches the observation in the problem, so the genotype of the parents is most likely Tt and Tt (option D).

What is a truck's acceleration if the net external force on the truck is 560 N and it has a total of mass of 1000 kg?

Answers

Answer:

0.56m/s²

Explanation:

The above is the correct answer.

Force = mass x acceleration = mg

⇒ F = mg

where F = 560 N, m = 1000kg

∴ g = F/m = 560/1000 = 0.56

∴ acceleration, g = 0.56m/s² (answer)

Force is known to be a push or a pull which actually puts a body to motion or brings a body to rest.  It has to do with the interaction between bodies.

Answers

Answer:

In biomes the species community undergoes certain changes in evolution and growth in order to reach the climax.

Explanation:

An alternative stable state is one which suggests the discrete states are sperate by an ecological threshold and in opposition to the ecosystem that is changing and thereby stating that the ecosystem can exist in a variety of alternative state.  The first species after origin grows develops and then declines. This community of species may be disturbed in middle such as by a fire or flood and forms the secondary community which is more diamine and resistant. The changes are known as seres in biomes.

An individual with two different versions of a gene is genetically ____________ . In traits with a simple pattern of inheritance, only the trait conferred by the ____________ form of the gene will be visible. The other form of the gene is ____________ : it confers a trait that is only visible when the individual is genetically ____________ , or has two identical copies of the gene.

Answers

Answer:

heterozygous; dominant; recessive; h.o.mo-zygous

Explanation:

Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.

In Genetics, co-dominance can be defined as a phenomenon in which two (2) alleles of the same gene are present in a living organism and both are equally expressed to a degree or simultaneously.

This ultimately implies that, co-dominance is a phenomenon that typically involves the relationship between alleles i.e the two (2) versions of a gene present in living organisms. Also, a single version of a gene expressed by a living organism is referred to as an allele.

Trait can be defined as a distinguishing quality or characteristic of a living thing.

Simply stated, a trait refers to the specific features or characteristics possessed by a living organism. It is essentially transferred from the parent of a living organism to her offspring and as such distinguishes him or her.

Some examples of traits in genetics are colorblindness, handedness, curly hair, height, complexion, weight, hair color, dimples, tongue-roll, etc.

In Genetics, when an individual has two (2) different versions of a gene, he or she is said to be genetically heterozygous.

In traits with a simple pattern of inheritance, only the trait conferred by the dominant form of the gene from the parent organism will be visible in the offspring of a living organism. The other form of the gene is recessive : it confers a trait that is only visible when the individual is genetically , or has two identical copies of the gene.
