What's the definition of absoulute dating
Absolute dating is the process of determining an age on a specified time scale in archaeology and geology. Some scientists prefer the terms chronometric or calendar dating, as use of the word "absolute" implies an unwarranted certainty and precision. Absolute dating provides a numerical age or range in contrast with relative dating which places events in order without any measure of the age between events. In archeology, absolute dating is usually based on the physical, chemical, and life properties of the materials of artifacts, buildings, or other items that have been modified by humans and by historical associations with materials with known dates. Techniques include tree rings in timbers, radiocarbon dating of wood or bones, and trapped charge dating methods such as thermoluminescence dating of glazed ceramics. Coins found in excavations may have their production date written on them, or their may be written records describing the coin and when it was used, allowing the site to be associated with a particular calendar year.

4. Which type of microscope
produced the image of cilia?
5. What type of microscope
would be best for studying cilia
Answer:
Scanning electron microscope and electron microscope.
Explanation:
Scanning electron microscope is a type of microscope which can produced the image of cilia. Electron microscope is a type of microscope would be the best for studying cilia because it has higher magnification power i. e. 10,000,000x, which able us to study different parts of cilia so we can say that electron microscope is the right choice for studying cilia.
Which device works similar to the way kidneys work in the human body? HELP IM BEING TIMED!!!
Hemodialysis uses a machine to pull blood out of the body, filter it, and pump the clean blood back into the body again. The actual filtering happens in a part of the machine called a dialyzer, or artificial kidney. The dialyzer has two parts. One part is for blood.

All of the following are true of spermatogenesis EXCEPT: Question 4 options: One spermatogonium produces 4 spermatids Genetically diverse spermatids are created. The products are spermatozoa that each have a head, midpiece and tail. DNA replicates once, but cells divide twice. Spermatids containing 23 chromosomes (1n) are produced.
Answer: The products are spermatozoa that each have a head, midpiece and tail.
Explanation:
The spermatogenesis can be defined as the process of gamete production in human males. It takes place in the testes in males. In this process the spermatids are produced which are four in number through reductional cell division called as meiosis. Each spermatid is haploid in number and the genetic material present in each is diverse as a result siblings are not identical to each other. The spermatozoa is an immature sperm cell which develops head, middle piece and tail. But it is not a precursor of production of sperm cells via cell division.
Why is it important for nerve impulses to travel rapidly?
Answer:
The messages carried by neurons are called nerve impulses. Nerve impulses can travel very quickly because they are electrical impulses. ... The sheath covers the axon, like the plastic covering on an electrical wire, and allows nerve impulses to travel faster along the axon.

What is the major difference during cytokinesis in eukaryotes with or without a cell wall?
Answer:
Cytokinesis in eukaryotic animal cells do not have a cell wall, it occurs through a strangulation process carried out from the plasma membrane, this process is called segmentation. Plant cells are characterized by cytokinesis based on septate, since the cell wall does not allow strangulation.
Explanation:
Cytokinesis means: cell division, it is a cellular process parallel to mitosis whose purpose is the division of the stem cell's cytoplasm between daughter cells. In animal cells, cytokinesis occurs by cleavage. At the end of anaphase and during telophase, the central part of the cell narrows, forming the segmentation groove, which deepens (strangulation). Plant cells, as they lack centrosomes, will form the achromatic spindle from two polar caps. In this case, cytokinesis does not occur by strangulation, but a cell wall is formed between the two daughter cells. This septum, called a fragmoplast, is formed from vesicles from the Golgi apparatus.
The major difference during cytokinesis in eukaryotes with or without a cell
wall is in the formation of cell plate in cells with cell wall while in animal
cells cytokinesis occurs through the formation of a cleavage furrow.
Cytokinesis is the process of cell division in which the cytoplasm divides
into two. Plants have cell walls while animals lack cell walls.
Animal and plant cells form cleavage furrow and cell plate respectively
which aids division into two equal parts.

Explanation:
Hoped I helped you out please mark me brainliest!!!
With the creation of the microscope, humans were able to observe plant and animal cells, and as technology advanced, scientists were able to learn more about these various types of cells.
What is a microscope?A microscope is a device that can be used to examine small objects, including cells. The image of an object is magnified in the microscope by at least one lens.
In most cases, the light is focused on the sample by passing it through a condenser.
After passing through the sample, the light passes through the objective lens, which magnifies the image of the sample, and then to the oculars, where the enlarged image is viewed.
The discovery of the green fluorescent protein (GFP), the development of increasingly sophisticated microscopes, and the development of in vitro assays that faithfully reproduce cellular functions are just a few examples of technological advances that have fueled many areas of cell biology.
Thus, it can be concluded that the advancements in technology help scientists better understand process of cell division.

Here is a pedigree for colorblind (H)
What is fred's genotype?
Answer:
[tex]x^{h} y[/tex]
Explanation:
Fred has inherited the colorblind trait from his mother. We know this because his spot on the pedigree is filled in. Because he is a male his genotype must be some variation of xy and because he is colorblind he must have the recessive "h" on his x chromosome. So his genotype (genetic type) is [tex]x^{h} y[/tex]

Explanation:

why would an athlete need to be concerned about a twitch or sustained contraction
Answer:
why an athlete would need to be concerned about twitches or contractions is because, whenever they perform, and such thing happens, it will most likely distract the athlete, and cause the athlete doing his/her performance to not be as good, and may lead to failure, for example, when someone is running very fast for a sprinting race, and he has a contraction in his leg it will cause him to react by showing signs of pain by slowing down or even tripping and falling, causing him to lose the race.
