How does cooling of magma affect crystal size?
A) Slow cooling creates small crystals
B) Fast cooling creates both large and small crystals.
C) Slow cooling creates large crystals
D) Fast cooling create large crystals
Answer:
When magma cools, crystals form because the solution is super-saturated with respect to some minerals. If the magma cools quickly, the crystals do not have much time to form, so they are very small. If the magma cools slowly, then the crystals have enough time to grow and become large.
Answer:
I learned about this, Uhm...
C is the right answer bc igneous rocks cool and form crystals.
Lava, since it comes out of a volcano, cools faster and has smaller crystals since they could not be developed enough.
Magma, still underground, cools slower than lava because of all the density and heat, which causes bigger crystals.
Hope this helps :)
Key Concept Name the
main events of the cell cycle.
You are part of a small group of humans rocketed at “warp speed” to Planet X, without any books, weapons, or technology. Planet X has no ozone layer to protect its surface from cancer-causing ultraviolet radiation, but native plants and animals have evolved to live safely there. Below the surface, the planet has a network of underground tunnels, just a meter high, which are inhabited by carnivorous predators.
Write 3 paragraphs using the vocabulary words we discussed today in class about how descendants of the group of humans would look and act after evolving for 100,000 years on Planet X.

Explanation:
Polydactyly is expressed when an individual has extra fingers and/or toes. Assume that a man with six fingers on each hand and six toes on each foot marries a woman with a normal number of digits. Having extra digits is caused by a dominant allele. The couple has a son with normal hands and feet, but the couple's second child has extra digits. What is the probability that their next child will have polydactyly
Answer:
The probability of the couple´s next child having polydactyly is 1/2 = 50%

Explanation:
6. In corn plants, normal height (H) is dominant over short height (h). Complete a
hybrid (heterozygous) cross.
Hybrid
Corn
н һ
Phenotype Probability (%)
H
Normal Height:
0%
Hybrid
Corn
h
Short Height: 0%
Answer:
See the answer below
Explanation:
Normal height - H
Short height - h
Heterozygous - Hh
A cross involving heterozygotes would be Hh x Hh
Hh x Hh
HH Hh Hh hh
Since H is dominant over h;
HH and Hh would produce normal height phenotypes.
hh will produce a short height phenotype.
Thus;
Probability of normal height phenotype resulting from the cross = 3/4 or 75%
Probability of short height phenotype resulting from the cross = 1/4 or 25%
Which word describes the process by which a human transmits a disease to an animal?
Answer: reverse zoonosis or anthroponosis.
Explanation:
Answer:
a zoonosis
Explanation:
is an infectious disease caused by a pathogen (an infectious agent, such as a bacterium, virus, parasite or prion) that has jumped from an animal (usually a vertebrate) to a human. Typically, the first infected human transmits the infectious agent to at least one other human, who, in turn, infects others
The cell membrane is ----------in nature
a. Highly permeable b. normally permeable c. not permeable d. partially permeable
Answer:
d. partially permeable
Explanation:
The cell membrane is the cellular organelle that covers and bounds all cells. It forms a boundary around a cell, protecting all other organelles. The cell membrane, according to the FLUID MOSAIC MODEL, contains phospholipid bilayer, proteins etc.
The phospholipid (lipid) content of the cell membrane confers its ability to be SELECTIVELY OR PARTIALLY PERMEABLE upon it. It is said to be partially permeable because it allows the passage of some molecules/substances and blocks the passage of others.

Burning fossil fuels for energy releases harmful emissions into the air. Which health concern is most likely related to these emissions?
A) Increases in blood cancers such as leukemia
B) Increases in skin disorders from absorption
C) Increases in respiratory illnesses such as asthma
D) Increases in digestive disorders from contaminated food
Answer:
Explanation:
its either c or b sorry if it is wrong
Answer:
C
Explanation:
If the harmful emissions are being released into the air, then the most logical answer would be an increase in respiratory illnesses auch as asthma.
It cannot be B or C because they specify that the disordera come from absorption and contaminated food, respectively.
It is most likely not A either.
6. Make connections: Why is it necessary for traits to be inherited for evolution to
take place?
Answer:
A condition necessary for evolution to occur is that a parent plant produces more offspring than can normally survive. ... A condition necessary for evolution to occur is that the traits of the "fittest" phenotypes that survive are inherited by the successful progeny. The offspring must tend to resemble their parents.

о
Answer:
O B. Restriction enzymes
Explanation:
Restriction enzymes has the ability to recognize specific DNA sequences and cut them in a specific manner in order to produced by the bacteria as a defense mechanism against foreign DNA containing substance such as viruses etc. This restriction enzyme is also called restriction endonucleases. This is a cloning tool that bacteria produced naturally in order to defend itself from the infection of virus.

Pairs of chromosomes contain (the same/different) types of genes.
Answer:
The 22 pairs of homologous chromosomes contain the same genes but code for different traits in their allelic forms since one was inherited from the mother and one from the father. So humans have two homologous chromosome sets in each cell, meaning humans are diploid organisms.

Oxygen is a product of the electron transport chain.
True or False
Answer:
true
hope this helps you ☺️☺️
Electron transport chain can be defined as the series of organic molecules and proteins which are embedded in the inner membrane of mitochondria. These molecules are involved in the shutting of electrons from FADH2 and NADH to the [tex]O_{2}[/tex].
The molecular oxygen is the final electron acceptor in this electron transport chain that leads to the formation of water and ATP as the end products. This chain takes place in the mitochondria in both animal and plant cells.
Hence, the given statement is true.
