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.

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.

Water is transpired through stomata, but carbon dioxide also must pass through stomata into a leaf for photosynthesis to occur. There is evidence that the level of carbon dioxide in the atmosphere has not always been the same over the history of life on Earth. Explain how the presence of a higher or lower concentration of atmospheric carbon dioxide would impact the evolution of stomata density in plants.
Answer:
Escribir en español, por favor.?
During those high-carbon-dioxide times, plants that produce fewer stomata,
when carbon dioxide levels are low, plants need many stomata in order to scrape enough carbon dioxide to survive.
How does carbon dioxide affect water uptake?Plant water use, an increase in atmospheric CO2 means that stomata, or the pores on leaves that exchange gases between the leaf and the atmosphere, do not need to open.
Thus, carbon dioxide levels are low, need many stomata in order to scrape enough carbon dioxide to survive.

1. At which type of boundary does new oceanic crust form?
2. Why is this type of boundary also known as a constructive boundary?
Answer:
1. the boundary that the ocean crust forms is the Divergent Boundary.
2. both these plates move apart and cause earthquakes.
Explanation:
1. these boundaries are known to crash against each other causing earthquakes, but these boundaries are also form the oceanic crust.
2. when they move apart they cause earthquakes and volcano's. an example of this is the Mid- Atlantic ridge.
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.

In cellular reproduction, ___ ALWAYS occurs in 5’ to 3’ direction
Answer:
DNA replication
Explanation:
DNA replication is the process whereby the genetic material (DNA) duplicates itself into two identical copies. This process must occur prior to any cellular division (meiosis or mitosis) in order to ascertain that each daughter cell gets an even and correct amount of DNA.
The process of DNA replication begins with the unwinding of the double stranded DNA molecule into two single strands of DNA. One strand called leading strand runs from 3'-5' while the other strand runs from 5'-3'. However, DNA replication proceeds in the 5'-3' direction.

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.

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.

how do scientists use rock layers to date fossils ? USE IN YOUR OWN WORDS.
40 POINTS DONT SKIP !
Answer:
By comparing a fossil to similar rocks and fossils of known ages, relative dating can be used to estimate its age. Absolute dating is a method of determining the precise age of a fossil by using radiometric dating to measure the decay of isotopes, either within the fossil itself or, more commonly, the rocks that surround it.

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
