2. Igneous rock that forms from lava that cools quickly on Earth's surface is called extrusive igneous rock. This type of rock is also known as volcanic rock.
3. The igneous rock with mostly light-colored minerals and just a few specks of dark-colored minerals is likely a felsic extrusive igneous rock, such as rhyolite.
4. The igneous rock with a high concentration of dark-colored, high-density minerals likely belongs to the mafic intrusive igneous rock category, such as gabbro.
5. Gabbro is an intrusive mafic igneous rock, which means that it formed from magma that cooled slowly beneath the Earth's surface, allowing for the formation of large crystals. Mafic refers to the high concentration of dark-colored minerals, such as iron and magnesium, which give the rock its characteristic dark color.

3. It's snowing and 30°F. If the temperature increases to 36°F, which of the following is likely to happen?
a. The snow will begin to evaporate
b. The amount of snow will increase
c. The snow will melt into rain
d. The snow on the ground will freeze
Answers
If the temperature increases from 30°F to 36°F while it is snowing, it is likely that "the snow will melt into rain," will occur.
When the temperature rises from below the freezing point (30°F) to above the freezing point (36°F), the atmospheric conditions change, causing the snowflakes to melt. The rising temperature provides the energy needed to break the hydrogen bonds that hold the water molecules together in the ice cubes. The effect of this is that frozen ice turns into liquid water.
Because the temperature has risen above the freezing point of water, the snow turns into rain. Individual water droplets are formed when the crystalline structure of snowflakes is lost. These drops can cause rain as soon as they fall from the sky.
Therefore, the correct option is C.

Answers
The children would be 50% colorblind.
What is colorblindness?
Colorblindness refers to the inability to see colors in a normal way. Colors like blue, green, red, etc. in some very rare cases, a person cannot see any color at all. Colorblindness is also referred as Daltonism, named after its founder- john Dalton.
Types:
Monochromacy: 2-3 cone pigments are absent or damaged (red, green, blue). This leads to complete colorblindness.
Dichromacy: only one cone pigment is absent/ damaged (red, green, blue). This leads to partial colorblindness.
Color blindness is mostly a sex-linked recessive disorder. If a colorblind woman married a man with normal vision, the children would be fifty percent colorblind.

Skeleton features cladogram
Answers
The main skeletal features used to construct a cladogram include the presence or absence of specific bones/structures, bone shape/structure, dental characteristics, skeletal adaptations, and skull morphology.
Cladograms are phylogenetic trees that illustrate the evolutionary relationships between different organisms. When constructing a cladogram, various skeletal features can be used as characters to determine the branching patterns and common ancestry among organisms. Here are some main skeletal features used in cladistic analysis:
Presence or absence of specific bones or structures: The presence or absence of certain skeletal elements, such as wings or limbs, can provide insights into evolutionary relationships.
Bone shape and structure: Comparing the shapes, sizes, and structures of bones can help identify shared characteristics and infer common ancestry.
Dental characteristics: The structure and arrangement of teeth, including the type and number of teeth, can provide information about evolutionary relationships and dietary adaptations.
Skeletal adaptations: Features like the presence of a notochord, presence of a bony skeleton, or modifications for specialized locomotion (e.g., wings, fins, limbs) can be used to infer evolutionary relationships.
Skull morphology: Examination of the skull, including the shape of the cranium, presence and structure of specific cranial bones, and jaw structure, can help determine evolutionary relationships and functional adaptations.
By analyzing these skeletal features and comparing them across different organisms, cladistic analysis aims to identify shared derived characteristics (synapomorphies) that indicate common ancestry and to construct a branching pattern that represents the evolutionary relationships between the organisms being studied.

Considering the p1 below, what is the probability of having a round,green, smooth pod? A. 9/64B. 27/64C. 1/16RrYyCc x RrYyCcR =roundr=wrinkledY=yellowy=greenC=smoothc=constricted
Answers
Round is a dominant characteristic. When crossing two heterozygotes, Rr x Rr, the dominant characteristic will be present in 3/4 of the offspring (being the offspring RR, Rr, Rr, rr), because dominant traits are expressed whenever there is a dominant allel (in this case, R) present.
Green is a recessive characteristic. When crossing two heterozygotes, Yy x Yy, the recessive characteristic will be present in 1/4 of the offspring (being the offspring YY, Yy, Yy, yy), because recessive traits only are expressed is homozygous pairs (rr).
Smooth is a dominant characteristic. It will happen the same as it happened with the Round characteristic. When crossing two heterozygotes, Cc x Cc, the dominant characteristic will be present in 3/4 of the offspring (being the offspring CC, Cc, Cc, cc), dominant traits are expressed whenever there is a dominant allel (in this case, C) present.
As the Principal of Independent Assortment states, different genes independently separates from one another, which means that the result would be a combination of the probabilities of each trait. Therefore, we must multiply the probabilities of having round pods with the chances of having green pods and small pods as well, as follows:
3/4 * 1/4 * 3/4 = 9/64
So, the correct answer is A. 9/64

Answer:
Cellular respiration releases C02 and water. This process leads to production of energy as ATPs. The objective is to extract the energy trapped in glucose and other metabolites. It begins in the cytoplasm and ends in the mitochondrial of cells. Since it involves liberation of energy as a spontaneous reaction, it has a positive entropy.

A) Trying to observe precursors such as foreshocks and changes to animal behavior.
B) Watching changes in weather patterns.
C) Using past earthquake patterns.
D) Predicting stress accumulation based on how recently an earthquake occurred.
Answers
Predicting stress accumulation based on how recently an earthquake occurred is not the method that has been used to predict earthquakes. The correct option is D.
What is earthquake?Earthquakes typically result from subsurface rock breaking unexpectedly and rapid movement along a fault.
The seismic waves that cause the ground to tremble are brought on by this quick release of energy.
When two chunks of the ground abruptly slide past one another, an earthquake results. The fault or fault plane is the area where they slide.
Erratic animal behaviour, such as fearful or puzzled pets, or birdcalls not typically heard at night, can be a clue that an earthquake is about to happen. Water levels in wells or artesian bores suddenly change.
It hasn't been possible to anticipate earthquakes by basing stress accumulation on how recently an earthquake happened.
Thus, the correct option is D.

These nerve terminals convert vibrations into electrical impulses, which travel to the brain via the eighth cranial nerve (auditory nerve). It is made up of little hair cells that border the cochlea. These cells convert vibrations into electrical impulses, which sensory nerves carry to the brain.

Answers
Answer:
a.) The electrons provide energy for the H+ pump to transport more H+ ions into the thylakoid space.
d.) The photolysis of water releases H+ ions into the thylakoid space.
Explanation:
The thylakoid, which is found in the chloroplast, is the site of the first stage of photosynthesis (LIGHT DEPENDENT STAGE) in the cells of plants. The light stage of photosynthesis functions to produce energy (ATP) and NADPH for the second stage called Calvin cycle.
However, this ATP is generated by the power realized from the pumping of Hydrogen ions (H+) into the thylakoid lumen. The following causes the build up of H+ ions in the thylakoid space:
- Light photon hits the chlorophyll molecule, which is the photosynthetic pigment, to become charged. The electrons (e-) generated from this provide energy for the H+ pump to transport more H+ ions into the thylakoid space.
- Photolysis of water, which involves the splitting of water to produce hydrogen ions (H+) causes a build up of H+ in the thylakoid space.
