Answer:
The similarities and differences between DNA and RNA are given as follows:
Explanation:
Similarities:
Both are made up of nucleotides
Nucleotides are made up of nitrogenous bases, a pentose sugar, and the phosphate backbone.
Both DNA and RNA have four nitrogenous bases each - two purines two pyrimidines
Purine binds with pyrimidines
Differences
DNA uses the nitrogenous bases adenine, cytosine, thymine, and guanine whereas RNA uses adenine, cytosine, uracil, and guanine. Uracil lacks a methyl group on its ring
RNA contains the sugar ribose that has an extra -OH while DNA contains the deoxyribose sugar that has H at the 2 carbon.
DNA is double-stranded while RNA is a single-stranded
Under alkaline conditions, DNA is stable while RNA is not stable.

This could be wrong but, he said that we take 50% from each parent.
23 from mom and 23 from dad to make up the full 46. Each of those chromosomes carry a specific genetic code.

Roles of bones in bony fish include which of the following?
a for general protection and support
bas places of attachment for muscles
x
to protect the fish's brain
d all of the above
Answer:
D All of the above
Explanation:
Like our bones, bones in fish can provide general protection and support to their body.
(Fun fact, jellyfish do not have bones, so when they are out of the water, they loses their bell shape structure and looks more like a flat piece of jelly. But fish tends to look the same when it is in water and out of water.)
The bone is also where the muscles will attach to, which allows for movement.
(Imagine our fingers, the muscles in our fingers are attached to our bones, which allows us to do things like typing.)
Bones can also protect the fish's brain.
(Brain can be very fragile and soft, so having a hard structure around it can protect the brain. It's kind of similar to protecting the liquid egg in an egg shell.)

Go Deep! Look at the Parent Chromsomes and Key pictured below. Would it be possible for these parents to have a daughter with Hemophilia?
Answer: No, the daughter will be a carrier only.
Explanation: Hemophilia is a sex-linked recessive disorder. The recessive gene is carried on the X chromossome. Males have only one X chromossome, while females have 2. So, for a male individual to have hemophilia, it only needs the recessive gene to be on the X chromossome. In a female, the disorder is expressed when both X chromossomes has the recessive gene.
In the Parent Chromossomes picture shown, the father's X chromossome doesn't have the gene for hemophilia and the mother is heterozygous for the trait, i.e., she carries the recessive gene.
A daughter will inherit an X chromossome from the father and an X chromossome from the mother.
In this family, the daughter will inherit the X with dominant gene H for the father and has a possibility of inheriting another dominant gene H or recessive gene h from the mother.
For the daughter to be hemophiliac, she has to inherit 2 recessive genes. Since in either case she won't, she only inherits 1 recessive gene, the daughter will be a carrier for the trait, not have the disease.
Review the Protein to Trait Example. How did the differences in proteins lead to different traits for this feature?
Answer:
Proteins are responsible for shaping and growth of an organism.
Explanation:
The differences in proteins lead to different in traits because it is the protein that determines the trait. The gene's sequence is like language that instructs cell to manufacture a particular protein that is necessary for the growth and development of the organism. These proteins shaped the structure of organisms so we can say that difference in traits occur due to difference in their proteins.

The two conditions that a student needs to provide for seed germination are moisture and warmth. Thus, the correct options are B and D.
What is Seed germination?Seed germination may be defined as the complete process of seed development into new plants. It emerges from a seed, the seedling, and finally into the adult plant.
In winter, there is extreme cold outside, so the excess cold reduces the moisture of the soil. Hence, it is needed to provide moisture as well as warmth for the seed to grow and develop properly under normal conditions.
Therefore, the correct options for this question are B and D.

2. Understanding human strengths is a focus of which kind of psychology?
Answer:
Positive psychology
Explanation:
Positive psychology is understood as the scientific study of human well-being as well as the strengths that allow individuals, communities, and societies to prosper. The field of positive psychology is based on the belief that people want to have a life full of positive affect and satisfaction (hedonic well-being), as well as to have a life full of meaning (eudaemonic well-being), to cultivate the best within themselves and enhance their experiences of love, work and fun. In this way, positive psychology will consist, precisely, of the theoretical study, measurement, classification and construction of positive emotion (focusing on human strengths), commitment and life satisfaction, especially in relation to lifestyle and health.

1. How will photosynthesis affect the dissolved oxygen levels in the

Answer:
Vegetation- riparian vegetation directly affects dissolved oxygen by releasing oxygen into the water during photosynthesis. It indirectly affects dissolved oxygen concentrations because vegetation shading a stream may decrease water temperatures, and as temperature decreases dissolved, oxygen increases.

Humans lived with domesticated dogs over thousands of years which resulted in many breeds of dogs. Humans bred some dogs to have thick
coats to keep the dogs warm in cold climates while other dogs have thin coats that live in warm climates.
Which evidence supports the claim that dogs inherit these characteristics?
O
A. During mitosis, mutations occurred and the offspring's DNA stored this information
B. As dogs digested food, mutations occurred which changed the dog's physical appearance.
O C. Since dogs lived closely in contact with humans, the dog's genetic information remained the same.
D. During meiosis, new combinations of genetic information occurred, and the offspring's genes expressed this information.
Answer:
Did humans tame woolly mammoths or other megafauna?
Considering that some people are gifted with handling animals (e.g. horse whisperers), could paleoindians or other Pleistocene peoples have gained the confidence of woolly mammoths or mastodons to use them as transportation and other tasks, the way that Asian elephants are used today?
Fewer resources would be necessary for a human to travel long distances by riding on the back of a woolly mammoth or paleocamel, as the megafauna could graze and get energy. People may also have traveled by boat during late Pleistocene times (the kelp highway along PNW).
How could we test such a hypothesis? Cave art showing a rider on the back of one of the megafauna? A bridle and/or bit? A talisman worn by a camel is known to have been crafted from a meteorite(1), and so talismans or decorations might have adorned the hypothesized woolly steed. Metal was not a known technology during stone tool usage, as far as we know, though.
