Answer:
Approximately the number of individuals with each phenotype is:
RS-->0.75 x 1000 = 750rs--> 0.19 x 1000 = 190Rs--> 0.05 x 1000 = 50rS--> 0.05 x 1000 = 50Explanation:
Available data:
Two genes are hypothesized to be linkedThe map distance between the genes is thought to be 12 map units. Two heterozygous parents1000 offspring producedLet us say that the two diallelic genes are R (alleles R and r) and S (alleles S and s)
Heterozygous parents might have the following genotype RS / rs
We know that there are 12mp between genes, which means that the recombination frequency equals 0.12 or 12%.
0.12 of the gametes are recombinants and 0.88 are parentals. There are two types of parentals and two types of recombinant, so 0.06 + 0.06 are recombinants while 0.44 + 0.44 are parentals. This is:
Cross:
Parentals) RS/rs x RS/rs
Gametes) RS (parental) 0.44
rs (parental) 0.44
Rs (Recombinant) 0.06
rS (Recombinant) 0.06

Facial dimples and free earlobes are both considered dominant human traits. What are the expected phenotypes of the offspring of a female with dimples and free earlobes (DDFf) and a male with no dimples and attached earlobes (ddff)? Group of answer choices
Answer: 50% with dimples and free earlobes and 50% with dimples and attached earlobes
Explanation:
Since both the facial dimples and free earlobes are considered to be dominant human traits, this implies that the expected phenotypes of the offspring with regards to the scenario given in the question would be 50% with dimples and free earlobes and also there will be 50% with dimples and a attached earlobes.
50% with dimples and free earlobes and 50% with dimples and attached earlobes.
Dominant and recessive traits exist when a trait has two different forms at the gene level. The trait that first appears or is visibly expressed in the organism is called the dominant trait. The trait that is present at the gene level but is masked and does not show itself in the organism is called the recessive trait.Since both the facial dimples and free earlobes are considered to be dominant human traits, this implies that the expected phenotypes of the offspring with regards to the scenario given in the question would be 50% with dimples and free earlobes and also there will be 50% with dimples and an attached earlobes.

11. Two plants, both heterozygous for the gene that controls
flower color are crossed. What percentage of their offspring
will have purple flowers?
What percentage will have white flowers?
A white flowered plant is crossed with a plant that is heterozygous for the trait. The percentage of the offspring will have purple flowers is 100%.
What do you mean by heterozygous?The presence of two different alleles at a particular gene locus. A heterozygous genotype may include one normal allele and one mutated allele or two different mutated alleles (compound heterozygote).
If the two versions are different, you have a heterozygous genotype for that gene. For example, being heterozygous for hair color could mean you have one allele for red hair and one allele for brown hair.
An organism with two dominant alleles for a trait is said to have a homozygous dominant genotype. Using the eye color example, this genotype is written BB. An organism with one dominant allele and one recessive allele is said to have a heterozygous genotype.

Here are some of the tRNA molecules in Lucy's white blood cells. Let's see if tRNA #1 is carrying the correct amino acid for its anticodon.
Using the RNA Pairing Rules, find the correct codon for this tRNA's anticodon.
Anticodon
CCA
Codon
Amino Acid
RNA Pairing Rules
A ↔ U
G ↔ C
Answer:
For the tRNA anticodon CCA the corresponding codon is GGU, which codes for the amino acid Glycine (Gly).
Explanation:
Transfer RNA or tRNA is responsible for driving the right amino acid into protein synthesis, once the mRNA codon has been translated by the ribosome. It is for that reason that each mRNA codon must have a complementary tRNA anticodon.
The RNA pairing rules is that each nitrogenous base has a complementary base, so:
- Adenine is complementary with uracil A=U
- Cytosine is complementary with Guanine C=G
In this case, it can be seen that:
For the anti-codon: CCACodon: GGUAminoacid: GlyAnswer:
For Anticodon it's: CCA
Codon it's: GGU
Amino Acid it's: Glycine (but when typing in the box for Amino Acid I typed in GGU and it was correct so that's the answer for Amino Acid.)

Answer:
Negative adaptations will become more common in a population
Explanation:
that's the one that is NOT a principle
Negative adaptations will become more common in a population is NOT a principle of evolution.
what is population ?A discrete accumulation identifiable characteristics such as people, animals with the objective of analysis and data collection is called a population.
A population consists of a same group of species who reside in a particular geographical place with their reproductive capacity to interbreed.
In a population Not all individuals are able to survive and reproduce due to genetic variations in them, a local population is restricted to a smaller area or can occupy a larger area, making up for the entire species.
when individuals in local populations spread between other local populations called as metapopulation.

How has human land use impacted the environment?
the answer is for anyone who needs it Ways that humans impact the environment is pollution and deforestation which can cause global warming and mass extinction. When humans pollute the earth they slowly start to cause global warming. When we burn fossil fuels to generate electricity, drive our cars, and power our lives we release heat trapping gasses into the atmosphere which slowly makes the world warmer. Deforestation get rid of some of our oxygen supply but it also can lead to mass extinction. When we cut down and burn trees it gets rid of animals homes. If the animals homes get destroyed they are forced to compete with other animals for their survival. Therefor one animal will survive while the other one dies and if this process occurs frequently it leads to many animals going extinct.
Answer:
Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water. These negative impacts can affect human behavior and can prompt mass migrations or battles over clean water.
Human activities causes extreme adverse conditions in the environment which resulted eben in the eventual devastation of some species from earth. The selfish actions of humans causes all kinds of pollution in nature.
What are human impacts?The term "human impact on the environment" (or "anthropogenic impact") refers to alterations to biophysical environments as well as to ecosystems, biodiversity, and natural resources.
Environmental changes made to meet societal requirements have negative repercussions. global warming, environmental deterioration (such as ocean acidification), mass extinctions and biodiversity loss, ecological catastrophe, and ecological collapse, to name only a few.
Population expansion, overconsumption, overexploitation, pollution, and deforestation are some human activities that harm the environment on a global scale.
It has been suggested that some of the issues, such as global warming and biodiversity loss, pose grave hazards to the existence of the human species.

Weak hydrogen bonds between the nitrogenous base pairs hold the two strands of DNA together. Why are the strands held together by weak hydrogen bonds instead of covalent bonds
Answer:
Explanation:
Hydrogen bonding is usually occur wen interaction with hydrogen atoms occur.
Hydrogen bonds joins DNA polymers because an hydrogen atom occur on on one base which is called hydrogen bond donors and another oxygen or nitrogen atoms on the base across from it which is called hydrogen bond acceptors.
Adenine “A” a purine and Thymine “T” a pyrimidine each have a donor and one acceptor, whereas Cytosine “C” a pyrimidine has one donor and two acceptors, and Guanine “G” a purine has one acceptor and two donors.
This atoms allows for hydrogen bond between them that gives them structure of DNA molecule.
A nucleotides is hydrogen bonded to T nucleotides while C nucleotides is hydrogen bonded to G nucleotide this is called complementary base pairing.

Would the distance from the Sun to the next closest star be more or less than
39.4 Astronomical Units? Why or why not?
Answer: The distance from the sun to the closest star would be less. I dont know why, but their is a star that is close to the sun. The average distance between them is about 23 astronomical units. 23 is of course less then the 39.4. Also the 23 is a little more than the distance between the sun and Uranus.
Explanation: ( This is new information, not old.)
The distance from the Sun to the closest star cannot be less than 39.4 AU because both stars will start attracting each other.
Astronomical Units:An astronomical unit is equal to the distance between the earth and the sun.The nearest star from our sun is Alpha Centauri which is 4.367 light-years away from our sun.If a star is just 34 astronomical units away from our sun, the sun and the closest star will start attracting each other due to the high gravitational force. This event results in the destruction of the solar system.Therefore, the distance from the Sun to the closest star cannot be less than 39.4 AU.
