Explanation:
In chickens, comb shape is determined by genes at two loci (R, r and P, p). A walnut comb is produced when at least one dominant gene R is present at one locus and at least one dominant gene P is present at a second locus (genotype R_ P_). A rose comb is produced when at least one dominant gene is present at the first locus and two recessive genes are present at the second locus (genotype R_ pp). A pea comb is produced when two recessive genes are present at the first locus and at least one dominant gene is present at the second (genotype rr P_). If two recessive genes are present at the first and the second locus (rr pp), a single comb is produced. Give genotypes for comb shape of the parents in the following cross: Rose crossed with pea produces 20 walnut offspring.
a. RR PP × rr pp
b. RR Pp × rr pp
c. Rr PP × rr pp
d. Rr Pp × rr pp
e. Rr pp × rr pp
Answers
Answer:
in the obtained options, there is no dominant gene for the crossed pairs, therefore, no answer would be correct, however, when assigning a dominant character to the P gene, the correct answer would be:
E. Rr pp *rrPp
Explanation:
According to the information obtained we deduce:
Comb shape is produced by R and P
Comb of walnuts with an R or a P
Pink comb: 1 dominant P and R at the first locus and 2 recessive at the next locus
Pea comb: 2 recessive at the start and one dominant in the next position
1 single comb: 2 recessive at both loci
Rr pp × rr Pp will produce from the interbreeding: 2 walnuts, 1 single and 1 pea offspring.
We deduce that for the pink comb the genotype is: Rrpp
and for the pea comb it is rrPp
Rr pp × rr Pp generates crosslinks containing RrPp, rrPp, rrpp as children in a 2: 1: 1 ratio.

Answers
Answer:
The orographic effect creates cooler air moving up the windward side of mountains and warmer air moving down the leeward side. Often, as the leeward air plunges down the slope, it warms quite dramatically and rapidly. Such rapid warming and drying of air can produce very high winds known as Chinook or Foehn winds.

Land subsidence is caused by

O runoff
O gophers

Answers
Answer:
groundwater overpumping
Explanation:
Land subsidence occurs when large amounts of groundwater have been withdrawn from certain types of rocks, such as fine-grained sediments. The rock compacts because the water is partly responsible for holding the ground up. When the water is withdrawn, the rocks falls in on itself.

Biologists notice that a population of ferrets introduced into a reserve begins to show exponential growth. The figures represent the population of the ferrets for the first four years after their introduction. Which set of figures represents the exponential growth of the ferrets? A. 50, 88, 145, 227 B. 50, 92, 90, 95 C. 50, 32, 17, 9 D. 50, 95, 59, 97
Answers
Answer:
A. 50, 88, 145, 227
Explanation:
The correct option would be option A.
When something grows exponentially, it means the growth increased at a high rate. More specifically, each rate of increase results in more or less doubling of the preceding rate. For example, if the current value of growth rate is 2 for a substance that is growing exponentially, the next growth rates will be 4, 8, 16, etc.
In this particular illustration, the only option that best fit into an exponential system is option A in which the growth rate more or less doubles each time from 50 to 88, from 88 to 145, and then from 145 to 227.

A

15. Knowing that the genetic code is almost universal, a scientist uses molecular biological methods to insert the human B-globin gene into bacterial cells, hoping the cells will express it and synthesize functional B-globin protein. Instead, the protein produced is non-functional and is found to contain many fewer amino acids than does B-globin made by a eukaryotic cell. Explain why.
Answers
Answer:
The genetic information of living organisms is sequenced in DNA, which allows inheritable factors to be transmitted with each replication process. Proteins play a very important role by intervening in their metabolism during the translation and transcription of information. .
eukaryotic and prokaryotic organisms have different evolutionary sequelae that are reflected in the mechanisms they use for DNA translation, such as in the initial stages, lengthening and termination of sequencing, these differences are imparted by the order of the genes, the ribosome and its structural form and the promoter sequences.
In this way we can conclude that although the eukaryotic genes enter into a bacterium, the type of information that they take may arrive incomplete and this may generate subsequent defects for their operation, but there may be processes that guarantee a better transfer of information with the use of genetic engineering and enzyme management to introduce different bacterial genetic expressions with eukaryotic genes.
Eukaryotic cells like humans and prokaryotic cells like bacteria vary in central dogma methods.
The generative data of an organism is stored in the sequenced DNA that gets transferred during the process of replication.
The DNA transcription and translation process in prokaryotes and eukaryotes differ like the steps concerned in the beginning and the termination of the arrays are defined by various sets of genes in both types of organisms.
The promoter, ribosomes and the structural genes make both the organism distinct from each other.
So, when the eukaryotic gene intrudes bacteria may lack some data that can get misinterpreted and the resulted proteins or amino acids will differ.

Jaden’s mass is 50 kilograms. His weight on Earth is
Answers
Answer:
Weight of the Jaden on earth is 490 N.
Explanation:
Formula
w = mg
Where w is the weight of an object , m is the mass of an object and g is acceleration of gravity .
Gravity on Earth is 9.8 m/s² .
Jaden’s mass is 50 kilograms.
g = 9.8 m /s²
m = 50
Put the values in the formula
Thus
w = 50 × 9.8
= 490 kg m /s²
(As N = kg m/ s²)
= 490 N
Therefore the weight of the Jaden on earth is 490 N.
How is electricity generated in the simulation?
Answers
Answer:
(LONG RESPONSE!)
In this work, several simulations and analyses are carried out to investigate the feasibility of generating electricity from underwater sea currents at Istanbul Bosphorus Strait. Bosphorus is a natural canal which forms a border between Europe and Asia by connecting Black Sea and Marmara Sea. The differences in elevation and salinity ratios between these two seas cause strong marine currents. Depending on the morphology of the canal the speed of the flow varies and at some specific locations the energy intensity reaches to sufficient levels where electricity generation by marine current turbines becomes economically feasible.
In this study, several simulations are performed for a 10 MW marine turbine farm/cluster whose location is selected by taking into account several factors such as the canal morphology, current speed and passage of vessels. 360 different simulations are performed for 15 different virtual sea states. Similarly, 8 different configurations are analyzed in order to find the optimum spacing between the turbines. Considering the spatial variations in the current speed within the selected region, the analyses are performed for three different flow speeds corresponding to ±10% change in the average value. For each simulation the annual energy yield and cluster efficiency are calculated.

Answer:
Conservationists are responsible to preserve or improve the biodiversity in ecosystem. Many wildlife sanctuaries are made to protect the biodiversity. There are several ways by which conservationists accomplish their aim such as monitoring populations of organisms to detect changes and promoting importnce of wildlife.
Two main challenges conservationists will face while monitoring population of organisms in wild are:
weather conditions may not support the monitoring equipments or clothing.Wildlife animals are dangerous and can cause harm.Hence, conservationists face the above challenges while dealing with wild.
Answer:
One challenge is cost. To effectively monitor populations in the wild, scientists need special equipment such as cameras, computers, and GPS monitoring equipment. Another challenge is accuracy. It’s impossible to count every single organism in an ecosystem, so scientists often work with estimates.
