Answer:
The correct answer is - NO.
Explanation:
To be specific to the question, the answer would be no as analogous structures do not show that two distinct come from a common ancestor. However, it shows the evolutionary relationship by stating that the species have different evolutionary origins and developmental patterns as they developed the organs with similar function and appearance but anatomically and embryological development is different.
The answer to the question "Do wings show that a fly is related to a bird?", is no it does not show the relation between fly and bird.
Which is part of microevolution?
Answer:
Microevolution is the change in allele frequencies that occurs over time within a population. This change is due to five different processes: mutation, selection (natural and artificial), gene flow, gene migration and genetic drift.
Explanation:
Between 1984 and 2003, scientists mapped the human genome, which means they determined the pattern of billions of genes that make a human a human. Originally, it took years to map a single person’s total genome. By 2014 multiple genomes could be mapped in one day. What most likely allowed scientists to start mapping so much faster? a change to Mendel’s law of dominance more powerful computer technology the discovery of how germs work new scientists repeating gene experiments
Answers: a change to Mendel’s law of dominance
more powerful computer technology
the discovery of how germs work
new scientists repeating gene experiments
Answer:
More powerful computer technology
Explanation:
More powerful computer technology allowed the scientists to start mapping so much faster because powerful computer works very fast as compared to human brain. The activity or calculation which can be done by the human brain in hours, the computer done it in seconds due to its fast and quick response. So we can conclude from this discussion that powerful computer technology allowed the scientists to start mapping very fast.

What are two major types of white blood cells? Describe them
Answer:
The two main types of leukocytes are granulocytes and mononuclear leukocytes (agranulocytes). Leukocytes arise from hemopoietic stem cells in the bone marrow. Leukocytes are involved in pathogen recognition, phagocytosis (ingestion of particles), pathogen destruction, inflammation mediation, and antigen presentation.
Explanation:
Hope it helps!:)
Answer:
granulocytes and agranulocytes. Granulocytes have visible granules or grains inside the cells that have different cell functions. Types of granulocytes include basophils, neutrophils, and eosinophils.

The Pelagic zone is divided into 5 vertical layers.
True
False
Answer : I thank its True I Hope it Can Help : )
Explanation:
Answer:
false
Explanation:
The vertical zones in the ocean include the epipelagic, mesopelagic and bathypelagic zones. The zones are based on the amount of light that penetrates the ocean waters. The epipelagic zone is also called the sunlit zone because it receives enough sunlight to support photosynthesis.
it is divided into three vertical layers
Cells have lots of membranes, which gives them a high amount of?
Answer:The plasma membrane
Both prokaryotic and eukaryotic cells have a plasma membrane, a double layer of lipids that separates the cell interior from the outside environment. This double layer consists largely of specialized lipids called phospholipids.
A phospholipid is made up of a hydrophilic, water-loving, phosphate head, along with two hydrophobic, water-fearing, fatty acid tails. Phospholipids spontaneously arrange themselves in a double-layered structure with their hydrophobic tails pointing inward and their hydrophilic heads facing outward. This energetically favorable two-layer structure, called a phospholipid bilayer, is found in many biological membranes. [Close-up of a phospholipid]
As shown below, proteins are also an important component of the plasma membrane. Some of them pass all the way through the membrane, serving as channels or signal receptors, while others are just attached at the edge. Different types of lipids, such as cholesterol, may also be found in the cell membrane and affect its fluidity.
An image of plasma membrane shows the phospholipid bilayer, embedded proteins, and cholesterol molecules. The membrane separates the extracellular space, outside of the cell, from the cytosol inside the cell.

The plasma membrane is the border between the interior and exterior of a cell. As such, it controls passage of various molecules—including sugars, amino acids, ions, and water—into and out of the cell. How easily these molecules can cross the membrane depends on their size and polarity. Some small, nonpolar molecules, such as oxygen, can pass directly through the phospholipid portion of the membrane. Larger and more polar, hydrophilic, molecules, such as amino acids, must instead cross the membrane by way of protein channels, a process that is often regulated by the cell. You can learn more about cellular transport in the membranes and transport section.
The surface area of the plasma membrane limits the exchange of materials between a cell and its environment. Some cells are specialized in the exchange of wastes or nutrients and have modifications to increase the area of the plasma membrane. For instance, the membranes of some nutrient-absorbing cells are folded into fingerlike projections called microvilli, singular, microvillus. Cells with microvilli cover the inside surface of the small intestine, the organ that absorbs nutrients from digested food. The microvilli help intestinal cells maximize their absorption of nutrients from food by increasing plasma membrane surface area. [Microvilli and celiac disease]

The cytoplasm
The part of the cell referred to as cytoplasm is slightly different in eukaryotes and prokaryotes. In eukaryotic cells, which have a nucleus, the cytoplasm is everything between the plasma membrane and the nuclear envelope. In prokaryotes, which lack a nucleus, cytoplasm simply means everything found inside the plasma membrane.
One major component of the cytoplasm in both prokaryotes and eukaryotes is the gel-like cytosol, a water-based solution that contains ions, small molecules, and macromolecules. In eukaryotes, the cytoplasm also includes membrane-bound organelles, which are suspended in the cytosol. The cytoskeleton, a network of fibers that supports the cell and gives it shape, is also part of the cytoplasm and helps to organize cellular components.
Even though the cytosol is mostly water, it has a semi-solid, Jello-like consistency because of the many proteins suspended in it. The cytosol contains a rich broth of macromolecules and smaller organic molecules, including glucose and other simple sugars, polysaccharides, amino acids, nucleic acids, and fatty acids. Ions of sodium, potassium, calcium, and other elements are also found in the cytosol. Many metabolic reactions, including protein synthesis, take place in this part of the cell.

Discuss the challenges trying to do work in the field and how unanticipated problems occur in science and methods may need to be changed. For example, how did the crew change their method for getting close to the sharks? Why did they have to change their approach?
plz answer thissss
Also, my real name is Savannah ^w^
Answer: Correct approach is required to be taken for conducting the research.
Explanation:
The scientific methodology involves the observation, experimentation, deduction of the conclusion. Moreover, similar studies in the same field also add up to the literature and change in the methodology for a particular discipline of study to understand the scientific phenomena better. The unanticipated problems may include the physical, psychological, and economic harm to the subjects.
But according to the given situation the crew might have not taken protection while conducting research in the shark surrounding. Shark is a carnivore and can cause massive harm to the navigators so precautions are required to be taken to protect themselves and conduct research.

the grand canyon was carved, separating what had once been a single population of squirrel into two seperate populations. what do you think happened to those populations over time?
Answer:
They became different.
Explanation:
Since the populations were separated and were not able to interact, they could not reproduce. Eventually, mutations would work their ways into each of the separate populations of squirrels. Since the two populations can't mix their genes through breeding they will slowly start to get different. For example, one population could experience a mutation that changes the color of one animals in the one of the populations. This squirrel will spread its genes to its offspring and if it is a good trait then it will spread throughout the population. The other population will not experience a widespread invasion of this trait because the two populations can't breed.
