Answer:
Double Crossing-over prob = 0.3% Simple Crossing-Over prob A-B = 9.7%Simple Crossing-Over prob B-C = 2.7%Total Crossing-Over prob = 12.7%Explanation:
Available data:
order of the genes on a plant chromosome is A, B, CA and B are located 10 cM apartB and C are located 3 cM apartThe genetic distance = recombination frequency x 100 expressed in map units (MU). One centiMorgan (cM) equals one map unit (MU).
We can use the provided map with the distances between genes to predict the occurrence of any kind of recombinant gamete.
We know that there is a probability of a simple crossing over to occur between genes A and B, or between genes B and C. And we also know that there is a probability of double crossing-over occurrence.
We can get the probability of the double-crossing over by multiplying the recombination frequencies between A-B and B-C. So,
DCO prob = recombination frequency A-B x recombination frequency B-C
= 0.1 x 0.03 = 0.003 = 0.3%
DCO prob = 0.3%
According to this, we would expect to find
0.15% AbC0.15% aBcNow we need to know what are the probabilities of getting a simple crossing-over, SCO. We already have the genetic distances between genes. 10 cM equals 0.1 of recombination frequency, and 3cM equals 0.03 of recombination frequency. However, we can not estimate the probabilities of simple crossing over using only this information, because this data is including the probabilities of the double crossing-over occurrence. So we need to substrate this percentage.
SCO prob A-B = 0.1 - 0.003 = 0.097 = 9.7%
SCO prob A-B = 9.7%
we would expect to find
4.85% Abc4.85% aBCSCO prob B-C = 0.03 - 0.003 = 0.027 = 2.7%
SCO prob B-C = 2.7%
we would expect to find
1.35% ABc1.35% abCThe total Crossing-over probability, TCO, is then the sum of all the crossing over probabilities,
TCO= SCO A-B + SCO B-C + DCO
TCO prob = 9.7% + 2.7% + 0.3%
TCO = 12.7%
Some male birds are very colorful and stand out visually in comparison the their drab counterparts. They also may make loud
vocalizations during courtship. These visual and auditory signals may make then more likely to attract predators and be killed.
Evaluate the statements to find the best description for the evolution of male coloration and vocalization in birds.
-0,)
A)
Colorful and vocal birds may be eaten by predators with greater frequency,
so this is a poor adaptation.
B)
Colorful and vocal male birds may attract the most mates and pass on
their genes. This is an adaptive trait.
Colorful and vocal birds mimic their drab counterparts when predators are
nearby, so predators are just as likely to eat any member of the population.
O
D)
Colorful and vocal birds will only mate with colorful and vocal females,
meaning these groups will become a different species from their drab
counterparts.
Answer:
A)
Colorful and vocal birds may be eaten by predators with greater frequency,
so this is a poor adaptation.
Explanation:
Colourful and vocal male birds may attract the most mates and pass on their genes. Therefore, option (B) is correct.
What is evolution?Evolution is the process of gradual change in the characteristics of a population over time through the mechanisms of natural selection, genetic drift, and gene flow, resulting in the emergence of new species.
While it is true that colourful and vocal birds may be more visible to predators and more likely to be eaten, the fact that they have evolved to develop these traits indicates that the benefits of attracting mates and passing on their genes outweigh the risks of predation. Male birds use their coloration and vocalizations to attract females and demonstrate their genetic fitness, and females select mates based on these traits. Therefore, over time, the male birds with the most attractive traits will be more successful at reproducing, leading to the evolution and persistence of these traits in the population.

Understanding the molecular basis of life helped in developing many technologies some used to further discover the cell, and others used to diagnose diseases or create organs or perform surgeries. Choose one technology and describe it briefly indicating its uses. 2. In what ways might genetically engineered organisms pose a threat to the health and safety of human populations
Answer:
1- The CRISPR-Cas system
2- Genetically modified organisms raise concerns associated with allergic reactions, horizontal gene transfer and outcrossing
Explanation:
The CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats)-Cas (CRISPR-associated) technology is widely used in medicine and research. The CRISPR-Cas is a versatile RNA-programable genome editing system capable of introducing genetic modifications at target DNA sequences. This technology is based on the natural bacterial immune system that cleaves bacteriophages and plasmid DNA sequences. Moreover, Genetically Modified Organisms (GMO) have historically raised three major concerns on human health: 1-the allergenicity of GMO foods, 2-the ability that GMOs might have to insert genes through horizontal transfer and 3-outcrossing between GMOs and (genetically) unmodified crops, which are further consumed as non-GM foods.

From the list below select all statements associated with action potential depolarization phase.
Disregard the check marks.
The statements associated with action potential depolarization phase are: - Occurs as soon as threshold (-55 mV) is reached, Requires ionic concentration gradients, Involves sodium movement across the neuron's membrane, Mediated by voltage-gated channels, Involves potassium movement across the neuron's membrane
- Action potential is an electrical impulse that travels along the membrane of a neuron or muscle cell.
- Depolarization phase is the first phase of action potential, in which the membrane potential rapidly becomes less negative and moves toward a positive value.
- Depolarization phase is initiated when the membrane potential reaches a threshold value of -55 mV.
- The depolarization phase requires ionic concentration gradients, which are differences in the concentrations of ions such as sodium and potassium on either side of the cell membrane.
- During the depolarization phase, sodium ions move rapidly into the cell through voltage-gated sodium channels that open in response to the depolarization of the membrane potential.
- The influx of sodium ions causes the membrane potential to become more positive, further opening voltage-gated sodium channels and creating a positive feedback loop that rapidly depolarizes the membrane.
- The depolarization phase is mediated by voltage-gated channels, which are proteins that open or close in response to changes in the membrane potential.
- As the depolarization phase progresses, voltage-gated potassium channels also begin to open, allowing potassium ions to move out of the cell and repolarize the membrane.
- The movement of ions during the depolarization and repolarization phases of action potential is an active process that requires energy and is mediated by ion pumps and channels.

B. Crossing 2 plants w desirable traits
C. Inserting genes from one plant into another
D. Returning bred plants to their natural habitat
Answer:
b
Explanation:
they chose the best tomatoes to make even better ones
Breeding tomatoes to increase fruit size is an example of selective breeding. Therefore option A is correct.
Selective breeding, also known as artificial selection, involves the intentional breeding of plants or animals to promote desired traits. The process typically involves selecting individuals with specific characteristics and breeding them to pass on those traits to the next generation.
In the given options, breeding tomatoes to increase fruit size is an example of selective breeding. By carefully selecting tomato plants with larger fruits and allowing them to reproduce, breeders can gradually enhance the fruit size of future generations.
This process relies on natural genetic variation within the tomato population and human intervention to guide the breeding process toward the desired outcome.
