Answer:
Evolution of Polar Bears
Explanation:The fossil transitions leading to our knowledge of development of the Polar Bear species are very well documented. Bear fossils change through time; i.e., as higher levels of sediments and sedimentary rocks are examined, more recent fossils are found.
The observed fossil transitions that inform our knowledge of Polar Bear speciation are very well documented. Bear fossils change through time: generally, when examining the fossil record, successively deeper levels of sediments or sedimentary rocks yield successively older fossils. For some transitions from one species to another, one can find a well-characterized series of transitional specimens leading the observer across the species "boundaries" (Kurten, 1976).

So if there are 56 As, there will be _______ Ts
and
If there are 44 Gs, there will be _______ Cs.
If there are a 100 bases-pairs and 65 bases are Ts, there will be __________Gs. (Math required)

Explanation:
A always pairs with T, so 56 A's will pair with 56 T's
G always pairs with C, so 44 G's will pair with 44 C's
100 base pairs means there are 200 bases present altogether
out of 200, we have 65 T's so ultimately we will have 65 A's
we are now left with 70, of which have will be C and half G, which gives 35 C's and G's

What is the function of the Single Strand Binding Proteins (SSB. during DNA replication?
O to add new nucleotides to each strand of DNA
O to seal up the new nucleotides (Okasaki fragments) into long continuous strands
O to bind temporarily to each strand of DNA and keep them separated during replication
O to break the hydrogen bonds holding the two DNA strands together
Answers
Answer:
the correct answer is C.
Explanation:
Once helicase separates the strands by breaking the bonds between them, there's still some sort of attraction between the two strands. This is were the SSB's come in. They help to keep the strands apart, preventing them from coming back together.
The single-stranded DNA binding protein (SSB) wraps (ssDNA) during DNA replication with a strong affinity to shield it from deterioration and prevent the development of secondary structures. Option (C) is correct.
What is DNA Replication?
The formation of two identical copies of a double-stranded DNA molecule requires a process known as DNA replication. This process copies the DNA molecule so that it has both strands.
The requirement for replication results from the fact that whenever a cell divides, the two daughter cells must have the same genetic material, also known as DNA, as the parent cell. This makes it necessary for replication to take place.
The cytoplasm of prokaryotic cells and the nuclei of eukaryotic cells are the locations where DNA replication takes place. The basic processes involved in DNA replication are consistent regardless of where it is carried out. The development of the primary nucleoprotein complex substrate is essential for the processes of DNA replication, recombination, and repair. SSBs contribute to its formation.
Therefore, option (C) is the correct answer.

Mendel called the visible form the dominant trait and the hidden form the recessive trait. In the second generation, after plants were allowed to self-fertilize (pollinate themselves), the hidden form of the trait reappeared in a minority of the plants.

Sickle Cell anemia is a recessive trait that causes blood cells to be misshaped. A woman who has no history of sickle cell anemia marries a man whose father had sickle cell anemia. What are their genotypes?
Answers
Answer:
See the answer below
Explanation:
Let us assume the sickle cell anemia allele to be S and the alternate, non-sickle cell allele to be A.
Since the woman has no history of sickle cell in her family, she is totally free from the trait and, hence, would have the genotype of AA.
The man's father had sickle cell anemia. This means that the man has, at least, one sickle cell allele in his genotype with the other allele depending on the genotype of his mother. Hence, the man can be AS or SS depending on the genotype of his mother.

As the atmosphere and Earth's surface materials absorb ultraviolet light, visible light, and infrared energy, they gain thermal energy and their temperatures rise. Which of the following best explains why the dry and sandy areas of deserts are hotter than the water in oases, even when the areas are both at the same latitude and altitude?
A. Water's ability to moderate temperature is less than that of sand.
B. Water's ability to morerate temperature is greater than that of sand.
C. Water is a polar molecule that reflects heat energy with like eletrical charges.
D. Water is a polar molecule that attracts hear energy with opposite electrical charges.
Answers
B........................
The dry and sandy areas of deserts are hotter than the water in oases, because of the water's ability to moderate temperature is greater than that of sand. Thus, the correct option is B.
How does water moderate temperature?
Water has a high specific heat capacity which makes it absorb a lot of heat energy before it actually begins to get hot or raise the temperature of the water body. The specific heat of water has a huge role to play in the Earth's climatic conditions and it also helps to determine the habitability of many of the geographical locations around the globe.
The dry and sandy areas of deserts are hotter than the water in oases, even when the areas are both at the same level of latitude and altitude because of the water's ability to moderate the temperature than that of sand.
Therefore, the correct option is B.

In biochemical terms, explain what causes lactic acid buildup. (Your answer must include the words: anaerobic, oxygen, lactic acid, ATP)
Answers
Answer:
Lactic acid buildup occurs when there's not enough oxygen in the muscles to break down glucose and glycogen. This is called anaerobic metabolism. There are two types of lactic acid: L-lactate and D-lactate. Most forms of lactic acidosis are caused by too much L-lactate.
Explanation:
hope it helps
Lactic acid builds up in the muscles of mammals due to inadequate oxygen.
During rigorous activities, oxygen supplies become inadequate to generate the necessary energy in the form of ATP from normal aerobic respiration.
Thus, anaerobic respiration is used to supplement the energy needed during rigorous activities.
During aerobic respiration, the presence of oxygen ensures that the 3 steps are complete:
GlycolysisKreb's cycleElectron transport
For anaerobic, only glycolysis takes place and the pyruvate molecules generated are converted to lactic acid. In the presence of adequate oxygen, the lactic acid is converted back to pyruvates which then move into Kreb's cycle.
The 2 molecules of ATP generated from glycolysis are used to supplement the energy needed during rigorous activities.

4. What role do the muscles and blood vessels play in the negative feedback loop of thermoregulation?
A) integration centers B)sensors
C)stimuli
D)effectors
Answers
Answer:
D)effectors
Explanation:
Skeletal muscles constitute an additional effector in this feedback loop because they quickly contract in response to a drop in body temperature, hence option D is correct.
What is a negative feedback loop of thermoregulation?
Blood flow is decreased, and the environment loses less heat as a result because blood vessels close to the skin constrict. Shivering helps the body produce heat, which raises body temperature.
The body starts to sweat when the hypothalamus senses that it is too hot, trying to bring the body's temperature back down to normal. Sweating will cease after the body temperature has returned to normal.
Therefore, the muscles and blood vessels play as effectors in the negative feedback loop of thermoregulation, hence option D is correct.
