Answer:
DNA:
- is a single molecule that can be over 10,000,000 nucleotides long
- is usually double stranded
- includes the base thymine
- is the genome for prokaryotic organisms
RNA:
- can be translated into a protein
- is usually single stranded
- includes ribose sugar
- is a single molecule that can form a complex secondary structure
Explanation:
Deoxyribonucleic acid (DNA) is the hereditary genetic material of both prokaryotic and eukaryotic organisms, while RNA is the genetic material of many viruses. DNA is a double helix molecule composed of four types of nucleotides: a nitrogenous base (Adenine, Thymine, Cytosine and Guanine), a five-carbon sugar (i.e., deoxyribose), and a phosphate group. On the other hand, RNA is usually a single-stranded molecule whose nucleotides contain ribose sugars and Uracil bases replace Thymine bases. During translation, a type of RNA molecule referred to as messenger RNA (mRNA) is used as template to direct the synthesis of a polypeptide chain (protein). This RNA molecule can fold to form stable double-stranded RNA hairpins (i.e., secondary structures).

We have 13 different clotting factor proteins in our blood. Do you think hemophilia is controlled by one or multiple genes?
Hemophilia A and hemophilia B are inherited in an X-linked recessive pattern . The genes associated with these conditions are located on the X chromosome, which is one of the two sex chromosomes . In males (who have only one X chromosome), one altered copy of the gene in each cell is sufficient to cause the condition. Basically it's whatever you believe it is.

Which step in the Gram stain is the critical step in differentiating Gram negative cells from Gram positive cells?
Answer:
The rapid decolorization with ethanol or acetone
and counterstaining with safranin
When a decolorizer such as alcohol or acetone is added, it interacts with the lipids of the cell membrane. A gram-negative cell loses its outer lipopolysaccharide membrane, and the inner peptidoglycan layer is left exposed: when safranin is added they will turn red. Conversely, gram-positives retain the Cristal violet and will color in purple
how to cultivate yam
Explanation:
Yams are produced through slips, which have been generated again from sprouts of mature yams, rather than seeds, as most other crops are. Split a yam in part and place one half in a bowl of cool water to develop sprouts.

How do elephants warn their family groups of a dangerous predator in their habitat?
A. They use their trunks to make loud sounds.
B. They stomp their feet to create noise.
C. They use their tusks to kick up dirt.
D. They flap their ears rapidly.
Answer:
How do elephants warn each other?
When they're excited, scared or happy, elephants make the trumpeting sounds you're probably familiar with. They vocalize in other, more complicated ways, too — low-pitched rumbles outside our range of hearing. At less than 20 hertz, these infrasonic calls are often used to alert each other to danger.

Starting with spore dispersal, and identify adaptations in the life cycle of the bryophyte for living in a terrestrial environment (ie, in air, without water surrounding the plant body). What are new stresses associated with living on land, and what morphological or physiological features did the first land plants have to evolve to cope with these stresses
Answer:
Stresses such as lack of nutrients, space, competition and water availability.
Explanation:
Lack of nutrients, space, competition and water availability are the stresses that the bryophyte can experience by living on land. The morphological or physiological features such as lowering transpiration rate by stomata, attain specialized structures to collect sunlight and fulfill water requirement by absorbing water from the air if no water is available in the soil etc are the features that the plant has to attain to cope with these stresses.
The movement of these eroded particles to a new location is called deposition, which often results in distinct ___________ of sediments building up in a particular area.
Answer:
layers? maybe

how does the structure of simple cuboidal connect to its function
Answer:
Simple cuboidal epithelial tissue is specialized for diffusion and absorption. The reason our kidneys function the way they do is because of the movement of water and salts in and out of the kidney tubules.Likewise, the cuboidal shape of the cells allows greater surface area for absorption to take place.

At one time, Chondrichthyes were thought to have diverged from other vertebrates before the evolution of bone. Now we have concluded that the Chondrichthyes diverged after the evolution of bone had started. What does this change demonstrate about the evolution of fishes
Answer:
The correct answer would be - Characteristics can be lost in evolution.
Explanation:
The new evidence helps in developing a new hypothesis. In this case, new evidence proved that the Chondrichthyes diverged after the evolution of bone had started instead of before the evolution started. This process called atavism where an ancestral genetic trait reappears after having lost. This leads to loss of the traits in the evolution
This can take place by knocking the mutation out to overriding the gene by the old gene or overriding the new trait by the old trait during the evolution period.
At one time, Chondrichthyes were thought to have diverged from other vertebrates before the evolution of bone. Now we have concluded that the Chondrichthyes diverged after the evolution of bone had started might be their characteristics lost in evolution according to atavism.
What is atavism?
Recurrence in an organism of a trait or character typical of an ancestral form and usually due to genetic recombination. This leads to the loss of the traits in the evolution.
Hence, Chondrichthyes diverged after the evolution of bone had started might be their characteristics lost in evolution according to atavism.

Biomes are determined by
Answer:
Biomes are determined by their climate which is determined by percipitation and temperature
Explanation:
There are two main factors when scientists define a biome. One is the climate or the long-time average weather of a region. The other is the specific plants and animals in an area. The organisms in a biome often adapt to their environment. There are seven types of biomes based on these factors.
