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.

What characteristic of double-stranded DNA determines the ability of one strand to make an exact copy of the other strand?
O complementary pairing of bases
O hydrogen bonding between strands
O ability of bases to be connected in any order
O location of the base pairs in the center of helix
Answer:
The correct answer is ''complementary pairing of bases''
Explanation:
The double-stranded DNA with the complementary nitrogenous bases that are located inwards and establish non-covalent bonds (or attractive forces) to each other that maintain the structure of the molecule. Deoxyriboses (sugars) and phosphate groups constitute the columns of the molecule. When the cell divides, each new cell that is formed must carry all the genetic information that determines its characteristics and functions. For that, before dividing, DNA must replicate, that is, generate a copy of itself. During replication, the DNA molecule unwinds, separating its chains. Each of these will serve as a template for the synthesis of new DNA strands. The double-stranded DNA structure proposed by Watson and Crick (1953) suggested several important properties of the hereditary material: Complementarity rules of the nitrogenous bases A-T and G-C suggest a simple way of replication of the hereditary material. This simple form of replication is called a semi-conservative method. When DNA replicates, its two helices separate and each one of them serves as a template to synthesize a new helix following the pairing rules of nitrogenous bases.

Answer:the equator
Explanation:
How does the intensity of the sun's rays change as you move away from the equator?
Answer:
As incoming rays move further away from the equator, solar intensity decreases. This is due to decreasing incoming sunlight angles that result in the Sun's rays being spread out over a greater surface area of the Earth. ... The tilt of the Earth influences the amount of sunlight that a particular location receives.

how can Keeping track of what food you have and when it will go bad help prevent habitat destruction?
Answer:
It helps in the survival of organism which leads to prevent destruction of their habitat.
Explanation:
The available food and its shelf life are the information that helps the organisms to prevent destruction of their habitats because it provides information about in how many days the food can be eaten by the organisms which helps in surviving the organisms in the environment in which the food is limited. The wise use of available resources for the survival can help organism to survive in that environment and prevent to stop the destruction of their habitat completely.
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.
What produces toxic chemicals in the body?
