Giraffes and Elephants: Giraffes have adapted a long neck over time letting them eat and access food allowing them to survive. If a dry season was unusually long they would succeed fine because they are able to eat and drink from the trees. Elephants have survived with similar tactics of eating higher up, they have rough skin allowing them to outlast the heat, and only need water after long periods of time.
Why are subduction zones not commonly found at convergent continental-continental boundaries?
Answer:
the subduction zone is commonly found in convergent continental-continental boundaries since it is where two continental crusts meet, and the force forces one crust to subduct under another one.
Explanation:
For her science fair project, your little sister replicated one of Mendel's experiments. From a P0 pea plant with purple flowers and a pea plant with white flowers, she got 1 purple F1 hybrid (she had forgotten to water, so just one survived). From this self-fertilized F1 she got 8 F2 offspring. 7 were purple and 1 was white, for a 7:1 ratio. Did your little sister just disprove Mendel's laws
Answer: No, the 7:1 ratio is close to the expected 6:2 ratio even with the limited sample size.
Explanation:
Let the alleles be P (purple) and W (white).
The possible crosses are
PP x WW, PP x PW, PW x WW, PW x PW
the F1 is PP or PW
one F2 is white so the F1 must be PW and
the F2 are PP, WW, PW and
the expected 8 progeny are 2PP, 2WW, 4PW
Because 7/8 are purple, we can infer that P is dominant and W recessive, so the expectation is 6 purple, 2 white
The observed ratio is similar to the expected ratio, so we can’t say that this result disproves Mendel, particularly with a small sample.
7:1 is close to 6:2, even if the sample is smaller. We cannot invalidate Mendel with such a small sample size because the observed ratio was not statistically different from the anticipated ratio.
What is Mendelian Ratio?The term "Mendelian inheritance" refers to specific patterns that can be observed in the way characteristics are passed down from parents to children. In the 19th century, the Austrian monk Gregor Mendel conducted thousands of tests with pea plants in order to develop these broad patterns. He did this in order to determine the genetic makeup of pea plants.
The frequency with which diverse phenotypes are produced as a result of any cross incorporating Mendelian traits. in particular, the three to one ratio that is displayed by the second generation of descendants from parents who are different from one another in regard to a single character.

When do mountains get built?
Answer:
Movements of tectonic plates create volcanoes along the plate boundaries, which erupt and form mountains. A volcanic arc system is a series of volcanoes that form near a subduction zone where the crust of a sinking oceanic plate melts and drags water down with the subducting crust.

Are the Earth's seasons caused by the differences in the distance
from the Sun throughout the year or the tilt of the Earth's axis?
Earth's tilted axis causes the seasons. Throughout the year, different parts of Earth receive the Sun's most direct rays. So, when the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere. And when the South Pole tilts toward the Sun, it's winter in the Northern Hemisphere.

A rich variety of genetic material in an ecosystem will:
1. reduce the biodiversity of the ecosystem
2. decrease the carrying capacity of the ecosystem
3. reduce the likelihood of future medical discoveries
4. increase the chances that some organisms will survive change
A rich variety of genetic material in an ecosystem will increase the chances that some organisms will survive change.
What is an ecosystem?An ecosystem contains all the organisms and the biological environment (which contain abiotic and biotic factors ) with which they show interaction.
These biotic and abiotic components are related concurrently through nutrient and water cycles and energy discharges.
Energy joins the procedure through photosynthesis and is interspersed into plant tissue.
Thus, option 4 increases the chances that some organisms will survive change is correct.

Explanation:
Glucose is what type of molecule A: Multi- complex B: Protein C: Sugar D: Lipid
Answer:
Within all lifeforms on Earth, from the tiniest bacterium to the giant sperm whale, there are four major classes of organic macromolecules that are always found and are essential to life. These are the carbohydrates, lipids (or fats), proteins, and nucleic acids. All of the major macromolecule classes are similar, in that, they are large polymers that are assembled from small repeating monomer subunits. In Chapter 6, you were introduced to the polymers of life and their building block structures, as shown below in Figure 11.1. Recall that the monomer units for building the nucleic acids, DNA and RNA, are the nucleotide bases, whereas the monomers for proteins are amino acids, for carbohydrates are sugar residues, and for lipids are fatty acids or acetyl groups.

Why are invasive species dangerous to the environment?
A)They pollute the environment.
B)They are always predators.
C)They threaten biodiversity.
D)They bring abiotic factors.
Answer:
C
Explanation:
They threaten the other animals. They can take their food, homes, and they don't have natural predators.
Invasive species are dangerous to the environment as they threaten the biodiversity. Thus, the correct option is C.
Invasive species are those imported species that are able to thrive rapidly in another foreign area by adapting and reproducing quickly.
Invasive species of plants and animals lead to an increase in the competition for survival, which results in decrease in the population of the native species.
The invasive species also affect the food web that is existing in the particular ecosystem, because of which other all organisms which are part of the food web are affected. They outcompete the native species for food,
Thus, biodiversity is threatened due to the invasive species.

List and define the four main elements of the water cycle.
(SCIENCE)
Answer:
There are four main stages in the water cycle. They are evaporation, condensation, precipitation and collection
Explanation:
Evaporation- Is the the process in which water changes from a liquid to a gas or vapor.
Condensation- Is the process in which water vapor or gas in the air is changed into a liquid. Is the opposite of evaporation.
Precipitation- Precipitation is water from clouds in the form of rain, freezing rain, sleet, snow, or hail.
Collection- This is when water that falls from the clouds as rain, snow, hail or sleet, collects in the oceans, rivers, lakes, streams. Also some will soak into the ground and will collect as ground water.

What are the four possible gametes of an organism has the genotype KkMm?
Answer:
KM, Km, kM, km
Explanation:
Gametes, which are only produced during sexual reproduction, are formed as a result of meiosis. According to Gregor Mendel in his law of Segregation, alleles of a gene will separate into gametes in such a way that only one form of a gene (allele) will be present in each gamete.
In this question involving a dihybrid with genotype: KkMm, the allele combinations of the gametes that will be produced after meiosis are KM, Km, kM, km.

Fluoride levels in the bone would be higher in individuals with osteosarcomas.
Explanation:
Fluoride levels will be higher in bone of the individuals with osteosarcomas.
What are the uses of fluoride ?Fluoride is a group of compounds which is a combination of fluorine and other elements, these compounds are present in water, plants, rocks, air, and soil.
Some of fluoride compounds are sodium fluoride, stannous fluoride, and fluoride mono-fluorophosphate.
Once fluorides are absorbed inside the body, it travels into the blood through the digestive tract, tend to collect in areas with high calcium like bones and teeth.
Majorly fluorides are used in drinking water, beverages, food, and dental products, mostly fluoro-silicic acid, sodium fluorosilicate, and sodium fluoride forms are added to water.
Some of the fluoridated water used to prevent tooth decay, and avoid dental fluorosis, a cosmetic condition.
