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
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.
Conservationistis strive to preserve or improve biodiversity in ecosystems, which includes monitoring populations of organisms to detect changes. Name two challenges that scientists may encounter when they’re monitoring populations of organisms in the wild.
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.

You prepare an agar plate by spread plating & place an antibiotic disk in the middle of the plate. After incubating for a day at 37 degrees C, there are no bacteria on the plate. Which of the following is NOT a reasonable interpretation of what might have happened?
O The bacteria in the culture tube were already dead when you made the plate
O The medium used was defective and provided no nutrition for the bacteria
O The bacteria grew all over the plate but were then killed by the antibiotic
O The spreading tool was too hot when spreading the bacteria
Answer:
A.The bacteria in the culture tube were already dead when you made the plate
Explanation:
Antibiotics are the chemical substance used to kill or stop the growth of bacteria and some other microorganism.
Antibiotics are added to agar plate during experiment for the selection of only those bacteria with resistance to that antibiotic.
There can be several interpretation for the absence of bacteria such as:
The bacteria grows on the nutrients in the medium but due to defective medium they were unable to grow and die.It may also happen bacteria might have grown in all over the plate but due to the action of antibiotic, all the bacteria got killed.Tool used for spreading might kill bacteria as it was hot and bacteria may not be able to tolerate the excessive heat and die.Hence, the only not reasonable interpretation is bacteria in the culture tube were already dead when you made the plate.
So, the correct option is A.
Which of the following explains one of the ways plants and animals depend on each other?
A
Animals make minerals, which plants take in through their roots and pass up to their stems.
B
Animals release water vapor when they breathe, which plants take in through their leaves.
C
Animals make their own food, which plants take in through their roots and pass to their leaves.
D
Animals release carbon dioxide when they breathe, which plants take in to help make food.
Answer:
Animals release carbon dioxide when they breathe which plants take in to help make food
Animals release carbon dioxide when they breathe which plants take in to help make food. So the correct option is D.
Why do animals and plants depend on each other?
All species present on earth depend on each other for performing basic life processes. Humans are not able to survive beyond a particular range of temperature and pressure. For all the species to survive, a healthy environment is required.
Plants and animals are dependent on each other. This is because, in ecological systems, no species can survive alone. Animals are dependent on plants. Plants are the primary producers in our ecosystem. They produce food that is consumed by primary consumers and the primary consumers are consumed by secondary consumers.
Plants use carbon dioxide for photosynthesis and it results in the production of oxygen. This is used by animals for the process of respiration.
Plants depend on animals for several reasons. These can be fruit and seed dispersal, pollination, and also for the carbon dioxide that the animals produce. Thus, both plants and animals are interdependent on each other.
Therefore, the correct option is D.

Jaden’s mass is 50 kilograms. His weight on Earth is
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?
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.
