Answers

Answer 1

Answer:

The comparison of the ways in which iron-magnesium minerals and feldspars crystallize from magma is;

Feldspars continually react with magma and change composition but stay as feldspar whereas iron - magnesium react with magma and change into other minerals.

In Bowen's reaction series, feldspar minerals tend to continually change composition, whereas iron - magnesium minerals tend to have an abrupt change of their mineral types.

Now, the feldspars that are formed from cooling of magnma are usually very rich in calcium. Thus, as cooling continues, the feldspars will start reacting with the magma and as such the feldspar composition will undergo some changes. This reaction will lead to zoned crystals that have outer layers very rich in sodium while the core is very rich in calcium.

For the iron - magnesium minerals, when magma starts to cool, a mineral will now start to crystallize but the more the magma cools the more the temperature drops and a whole new mineral will be formed.

Finally, the minerals formed initially reacts with the magma which makes it to be converted into the new mineral.

Answer 2

Answer: the magma melts then hardens for a long time then iron magnesium pretty much sugar coats it and crystallizes it.

Why must there be variation in a population in order for natural selection to occur?
Beetle pollinators of a particular plant are attracted to its flowers' bright orange color. The beetles not only pollinate the flowers but mate while inside of the flowers. A mutant version of the plant with red flowers becomes more common with the passage of time. A particular variant of the beetle prefers the red flowers to the orange flowers. Over time, these two beetle variants diverge from each other to such an extent that interbreeding is no longer possible. What kind of speciation has occurred in this example, and what has driven it? A. Allopatric speciation, ecological isolation.B. Sympatric speciation, habitat differentiation.C. Allopatric speciation, behavioral isolation.D. Sympatric speciation, sexual selection.E.

Color blindness is a recessive trait. The gene for color blindness is on the X-chromosome. The family tree below shows the trait of color blindness. The only unknown is the mother in the first generation. What is true about the mother?

Answers

The true statement about the mother of this family tree is that she is a carrier for color blindness.

The correct option is (B).

What is color blindness?

Color blindness is a disability in which you are unable to see colors normally. Color deficiency is another name for it.

It is a condition in which a person is unable to distinguish between different colors.

The most common colors are greens and reds, but it can also happen with blues.

This condition is only dominant in males, but females carry this disability as recessive carrier, so they can transfer this gene to the next generation.

Thus, option (B) she is a carrier for color blindness is correct.

since males only need one recessive trait for it to show, and the father is not colorblind, the mother at least has to be a carrier for the colorblindness trait.

protein-coding gene

The genetic code is stored in the DNA of a cell. it is copied during the process of replication. An enzyme called helicase unwinds the double strand helix of DNA by breaking the hydrogen bonds that hold the two strands together, thus separating forming what is called replication fork. Next the enzyme DNA polymerase uses the single strands as a template and makes a new DNA strand by copying the template.

In what way does prokaryotic fission resemble eukaryotic mitosis?

Answers

The ways prokaryotic fission resemble eukaryotic mitosis are:

a. movement of chromosomes

b. genetically identical daughter cells

c. intracellular mechanisms

Chromosomes segregate, produce identical cells and it happens internally (to the cell) in both processes.

B. Cytotoxic T cells bind to infected body cells and destroy them
C. Helper T cells activate cytotoxic T cells
D. A macrophage consumes a virus and displays antigens on its surface and signals helper T cells to divide.

Answers

The primary immune response in humoral immunity, when we're talking about our body's natural defence capabilities against harmful foreign or domestic invaders would be when a macrophage consumes a virus and displays antigens on its surface and signals helper T cells to divide - D. This is usually our first line of defence found on the spot.

In 1831, Charles Darwin visited the Galapagos Islands. While observing the giant land tortoises that lived on these islands, Darwin noted that the shape of the tortoise shell varied depending on which island the tortoise lived. Tortoises on one island had round shells, for example, whereas tortoises on a neighboring island had more flattened, saddle-shaped shells. Which statement BEST summarizes Darwin's explanation for these differences?A) Random mutations caused the shape of the shells to fluctuate periodically. B) The shape of the tortoise shell varied because the predators on the islands were different. C) The particular shape of the shell was best suited for the island on which the tortoise was living. D) Tortoises who used their shells in special ways caused the shells to become larger, rounder, or flatter.
