why do waves that travel through basalt have a higher velocity than a wave traveling through sand?
Answer:
Hope i helped!
Explanation:
Even though the technology does not exist to travel into all of Earth’s layers, scientists can still learn a great deal about Earth’s structure through seismic waves. Seismic waves are vibrations in the earth that transmit energy and occur during seismic activity such as earthquakes, volcanic eruptions, and even man-made explosions. There are two types of seismic waves, primary waves and secondary waves. Primary waves, also known as P waves or pressure waves, are longitudinal compression waves similar to the motion of a slinky (SF Fig. 7.1 A). Secondary waves, or S waves, are slower than P waves. The motion of secondary waves is perpendicular to the direction of the wave travel, similar to the motion of vigorously shaking a rope

Explanation:
The equation of line e is y = 3/5x + 1. The equation of line f is y = -8/3x + 9/8. Are line e and
line f parallel or perpendicular?
Answer:
I think they're neither perpendicular nor parallel
Explanation:
Not parallel since slope of e (3/5) isn't equal to slope of f (-8/3)
Not perpendicular since the product of their slopes isn't equal to - 1.
=> (3/5)(-8/3)= - 8/5 and not - 1

Which would be the best way to measure the amount of loose rabbits on a farm?
A) count them all
B) Trap-mark-release
C) Sample count
D) Estimated guess
Answer:
Estimated Guess so D because if there are more then 10 rabbits you do not want to count every single one. So you would look at how many five are and see how many groups look like about 5 and then guess from there. So an estimated guess would quickly and easily get you a decent amount close to counting them.

Is it the male or female that determines the sex of a zygote? Based on chromosomes, how do we know this to be true
Answer:
The male
Explanation:
A female always gives one X chromosome, a male can give either an X or a Y. If a zygote receives an X from its father and another X from its mother, it will be female. If a zygote receives a Y from its father and an X from its mother it will be male. Because the mother only has one option of chromosome to give, her chromosomes will not effect the gender of the zygote.

What stage of meiosis is shown below?
A. Anaphase
B. Telophase II
C. Telophase
D. Anaphase II
Answer:d
Explanation:
In meiosis II, each single chromatid moves to the opposite pole. The cell present in the diagram is in the anaphase II stage. Hence, the correct option is option D.
What is meiosis?
Meiosis is a cell division in which four haploid daughter cells (n) are formed from a parent cell. This process completes in two phases, such as meiosis I and meiosis II. In meiosis I, there are prophase I, metaphase I, anaphase I, telophase I, and cytokinesis. In meiosis I, homologous chromosomes separate. At the end of meiosis I, two haploid cells (n) are formed.
These two haploid cells enter meiosis II. Meiosis II includes prophase II, metaphase II, anaphase II, telophase II, and cytokinesis. In prophase II, chromosomes constrict and shorten. In metaphase II, chromosomes align on a plane and attach to spindle fiber. In anaphase II, duplicated chromosome separates and starts to move towards the opposite pole. In telophase II, these chromosomes get closer to the poles, and cytokinesis starts.
Hence, anaphase II is the correct answer as daughter chromatids start to separate. option D is the correct.

What happens during interphase?
A.The chromosomes are duplicated.
B. Tetrads are pulled apart.
C. The spindles attach you chromatids.
D. Two haploid gametes are formed.
Chromosome duplication is the process that occurs during interphase. The correct option is A.
What is interphase?The interphase stage of the cell cycle is where the majority of the life of a typical cell occurs.
Interphase is the cell's "daily living" or metabolic phase, during which it acquires and metabolizes nutrients, grows, replicates its DNA in preparation for mitosis, and performs other "normal" cell functions.
A cell spends the majority of its time in what is known as interphase, where it grows, replicates its chromosomes, and prepares for cell division. The cell then exits interphase, goes through mitosis, and divides completely.
Thus, the correct option is A.

Using the images below, draw how plants and animals depend on each other.
Answer:
Plants and animals depend upon each other as mutual interdependence is must for their survival. Plants provide shelter for animals and they make oxygen for the animals to live. When animals die they decompose and become natural fertilizer plants. Plants depend on animals for nutrients, pollination and seed dispersal.
Explanation:
Answer: Plants and animals rely on each other for many things. One idea is that plants are a food sources for animals that are herbivores such as a rabbit. The animals that eat those herbivores, like a fox, are carnivores. Plants perform photosynthesis which is crucial to the survival of every organism on the planet including us humans. Through photosynthesis plants provide a source of energy and a release of oxygen. Plants can also be a habitat for other species. The CO2

or carbon dioxide that animals exhale is a key ingredient for photosynthesis. Another way animals benefit plants is that when they die they decompose and put organic matter and nutrients back into the soil for plants to use. Animals can also help a plant disperse it's seeds or act as pollinators.
