The ocean floor is not entirely flat, but has mountains and valleys. How did they get there? (Things to think about: age of crustal rock, mid-ocean ridges, plate tectonics Explain your answer.)
The shape of the ocean floor is due to a process called plate tectonics, which is that these floors are not flat, sandy expanses, they vary in every way such as underwater landscapes, with plunging valleys and towering mountains.
What is Plate tectonics?Plate tectonics is defined as the scientific theory that explains how the Earth's underground movements resulted in the formation of major landforms, including a number of events including the 1960s freeze-up, mountain building events, volcanoes, and earthquakes.
When plates collide and subduct, in which one plate moves beneath another, magma is produced, forming volcanoes. Many repetitions of this process have created the continents.
Thus, the shape of the ocean floor is due to a process called plate tectonics, which is that these floors are not flat, sandy expanses, they vary in every way such as underwater landscapes, with plunging valleys and towering mountains.

For dog coat color, the dominant S allele results in full pigmentation while the recessive si allele leads to white patches on the legs and belly called Irish spotting. Two fully-pigmented dogs have puppies with Irish spotting. What is the approximate fraction of offspring with Irish spotting expected from this cross
The approximate fraction of offspring with Irish spotting expected would be 1/4
Monohybrid crossingFor full pigmented dogs, the genotype would either be SS or Ss since S is dominant over s.
However, the two fully pigmented dogs gave birth to puppies with Irish spotting. Meaning that they are both heterozygous for the gene.
Thus:
Ss x Ss
SS Ss Ss ss
Offspring:
SS - fully pigmented - 1/4
Ss - fully pigmented - 1/2
ss - spotted - 1/4
Thus, the approximate fraction of the offspring with Irish spotting expected is 1/4.

how can we get dna out of human cells
Answer:
DNA can be extracted from ethanol-fixed lymphoid cells and tissues. The fixation procedure is simple and rapid, and the DNA extraction itself is the same as that normally used for fresh tissue or cells. DNA extracted from ethanol-fixed material is indistinguishable from DNA extracted from fresh samples based on its purity, its ability to be digested with restriction endonucleases, and its ability to specifically hybridize to DNA probes. The capability to extract DNA from ethanol-fixed cells and tissues eliminates the need for stringent handling and storage requirements of fresh or frozen specimens.
In a stem-and-leaf plot, the rightmost digit of each data value is the:.
Answer:
leaf
Explanation:
The leaf of each data value in a stem and leaf plot is determined from the rightmost digit of each number.
In a stem-and-leaf plot, the rightmost digit of each data value is the unit digit.
What is the data value in a stem-and-leaf plot?A stem and leaf plot may be defined as a type of plot where each data value is split into a leaf (the last digit) and a stem (the other digits). For example, 12 on the stem and 7 on the leaf read like 127, and 127 is written according to stem and leaf plot key 12 I 7.
The leaf of each data value in a stem and leaf plot is determined from the rightmost digit of each number — in this case, this is known as the unit digit. For example, the leaf of the first data value (63) is 3, and the leaf of the data value below it (57) is 7.
If you want to construct a stem and leaf plot, each observed value must first be separated into its two parts: The stem is the first digit or digits; The leaf is the final digit of a value; Each stem can consist of any number of digits.
Therefore, in a stem-and-leaf plot, the rightmost digit of each data value is the unit digit.

Explain implantation ?
Explain ovulation?
Implantation - About a week after the sperm has fertilized the egg, the fertilized egg has traveled to the uterus and has become a growing cluster of about 100 cells called a blastocyst. The blastocyst then attaches itself to the lining of the uterus (the endometrium). This attachment process is called implantation.
Ovulation - Ovulation is a phase in the menstrual cycle. It occurs at about day 14 of a 28-day menstrual cycle. Specifically, ovulation is the release of the egg (ovum) from a woman's ovary.

17 protons and 18 neutrons what is the mass number and atomic number
Answer:
The Atomic number is 17 and Mass number is 35
Explanation:
Given;No. of protons = 17No. of neutrons = 18To Find;Atomic numberMass numberSo, For Atomic number
Atomic Number = No. of protons = No. of electrons = 17 (Which is Chlorine {Cl} )
Now, For Mass number
Mass number = No. of protons + No. of neutrons
Mass number = 17 + 18 = 35
Thus, The Atomic number is 17 and Mass number is 35

What can we see with electron microscopes that we can't with light microscopes?
Electron microscopes reveal subcellular structures and nanoscale details inaccessible to light microscopes, thanks to their use of electron beams instead of light. This allows visualization of intricate cellular components and surfaces in unprecedented detail.
In place of light waves, electron beams are used in electron microscopes to illuminate specimens. Electrons offer substantially higher resolution since their wavelengths are shorter than those of visible light. This makes it possible for researchers to view subcellular elements such as organelles, protein complexes, and even single molecules.
In addition, by using methods like electron tomography, electron microscopes can view surfaces and structures in three dimensions. This ability is essential in subfields like materials science and cell biology where functionality is greatly impacted by nanoscale characteristics. The vacuum atmosphere of electron microscopy, however, necessitates sophisticated sample preparation, restricting observations of living species.
