Explanation:
Scientists believe that the polar bear in Alaska and the brown bear in Russia evolved from a common ancestor which would be responsible for this evolutionary change
Answer: don’t know really how to explain it but it’s geographic isolation
The process which is responsible for the evolutionary change among polar bears in Alaska and the brown bear in Russia is geographical isolation.
What do you mean by Evolutionary change?Evolutionary change may be defined as the heritable change which is seen in populations and species over a long period of time, due to several mechanisms such as natural selection, random genetic drift, erotic selection, and mutation.
The mechanism of geographical isolation is considered one of the important factors in causing speciation.
This happens when the individuals of the species may be isolated due to any physical means such as mountains, rivers, etc for a long period of time.
Therefore, the process which is responsible for the evolutionary change among polar bears in Alaska and the brown bear in Russia is geographical isolation.

Answer: capillaries
Explanation:
Answer:
Capillaries
Explanation: Fluid is forced out of capillaries (filtration) by blood pressure (hydrostatic pressure). As plasma is filtered, globular proteins are concentrated in the blood passing through the glomerulus, as globular proteins are too large to be filtered.

HYPOTHESIS: If 2 chambers of water are poured side-by-side, the warmer water will mix the cooler layer because it ___________
Answer:
Heat Transfer
Explanation:
If Two chambers of water are poured side-by-side, the warmer water will mix the cooler layer because the water molcules in a jar of hot water are more spread out and the two jars seek a balance of tempature.

In a paternity case, a woman (blood type O) claims a man (type A) whose mother is O to be the father of her
child. Is there any possibility the woman is correct? If so, show the genotypes of the people involved and a likely cross to produce a child with blood type O.
Answer:
Yes, the mother's claim might be correct.
Please find the genotype of the parents and the cross below
Explanation:
Blood group in humans is controlled by three alleles namely; iA, iB, and i. Alleles iA and iB are dominant over allele i but co-dominant when together i.e. iAiB
Based on this, below are the blood types of an individual with the possible genotype;
Blood type A - iAiA or iAi
Blood type B - iBiB or iBi
Blood type AB - iAiB
Blood type O - ii
According to this question involving a paternity case, a woman with blood type O claims a man with blood type A whose mother is type O to be the father of her child. The woman has a genotype 'ii' while the man has a heterozygous genotype 'iAi' because his mother will contribute the 'i' allele.
Hence, using the genotype of the woman (ii) and man (iAi) in a cross as follows; ii × iAi (see attached image for punnet square), the following proportion of offsprings will likely be produced:
(2) iAi - blood type A
(2) ii - blood type O
Therefore, the woman's claim that the man is the father of her child with blood type O (ii) is most likely correct.
B. How does its genotype and phenotype
differ from the non-circled offspring?
Someone answer me please
Answer:
Due to mutation.
Explanation:
The genotype and phenotype of circled offspring is different from the non-circled offspring because it has different genetic makeup, that is responsible for its different color. The change in the circled offspring's genotype was caused by a mutation. Mutation is a change that occurs in the DNA sequence, or genetic makeup of an organism due to mistakes when the DNA is copied or environmental factors such as UV light and smoke etc.

Explanation:
if all cells in an organism have the same DNA, the same genes why are there so many different types of cells in the human body for example there are nerve cells and skin cells and muscle cells
Answer:
The cell (from Latin cella, meaning "small room"[1]) is the basic structural, functional, and biological unit of all known organisms. Cells are the smallest units of life, and hence are often referred to as the "building blocks of life". The study of cells is called cell biology, cellular biology, or cytology.Cells consist of cytoplasm enclosed within a membrane, which contains many biomolecules such as proteins and nucleic acids.[2] Most plant and animal cells are only visible under a light microscope, with dimensions between 1 and 100 micrometres.[3] Electron microscopy gives a much higher resolution showing greatly detailed cell structure. Organisms can be classified as unicellular (consisting of a single cell such as bacteria) or multicellular (including plants and animals).[4] Most unicellular organisms are classed as microorganisms.
The number of cells in plants and animals varies from species to species; it has been estimated that humans contain somewhere around 40 trillion (4×1013) cells.[a][5] The human brain accounts for around 80 billion of these cells.[6]
Cells were discovered by Robert Hooke in 1665, who named them for their resemblance to cells inhabited by Christian monks in a monastery.[7][8] Cell theory, first developed in 1839 by Matthias Jakob Schleiden and Theodor Schwann, states that all organisms are composed of one or more cells, that cells are the fundamental unit of structure and function in all living organisms, and that all cells come from pre-existing cells.[9] Cells emerged on Earth at least 3.5 billion years ago.[10][11][12]

what is half-life of mercury-203
Answer:
The correct answer is - 47 days approximately.
Explanation:
In this given graph is the decay graph of mercury-203, there is a representation of the relation of change in the amount of the mercury -203 with the time in days. The red arch is showing the change of parent isotope percent with elapsed time and the green dashed arch showing the daughter isotope percentage with isotope.
The half-life is the required time to decay an element to half of its inital amount, according to the definition the half-life of parent isotope mercury-203 is the amount where the red arch is present at 50% in the graph that is 47 days approximately.
