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.

Answer: Introduced species or exotic species
Explanation:
The introduced species is also called as an exotic species. The exotic species is a species which is not native to a particular location or area but is introduced by humans either accidentally or with the desired species. Such species can be invasive means, it can compete with the native species for resources and can reduce the population of native species.
The given situation is an example of introduction of new species. The weeds are introduced exotic species which could have come along with the desired variety of wheat required for farming in the prairies.

Identify the statement below that is NOT a principle of evolution. O Populations evolve, individuals do not O Negative adaptations will become more common in a population O Variations occur naturally within a population Adaptations help individuals compete successfully for survival
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.

What feature of alcohol fermentation makes it more suitable for the baking process than lactic acid fermentation?
A. Alcohol fermentation generates NAD+ from NADH, but lactic acid fermentation generates NADH from NAD+.
B. Carbon dioxide gas is produced as a by-product of alcohol fermentation but not lactic acid fermentation.
C. Yeasts can use alcohol fermentation, but only human muscle cells can use lactic acid fermentation.
D. The products of alcohol fermentation are edible but those of lactic acid fermentation are not edible.
Answer:
The correct answer is : B. Carbon dioxide gas is produced as a by-product of alcohol fermentation but not lactic acid fermentation.
Explanation:
In t5he lactic fermentation, the end product is lactic acid whereas in Alcohol fermentation produces by-product carbon dioxide gas which makes it more suitable for baking.
Alcohol fermentation takes place the bread is made as gas is what puts tiny air bubbles within the dough of the bread and makes bread lighter consistency we are used to. Yeast helps in producing carbon dioxide by alcohol fermentation.
Answer:
B. Carbon dioxide gas is produced as a by-product of alcohol fermentation but not lactic acid fermentation.

9. In pea plants purple flowers are dominant to white flowers.
If two white flowered plants are cross, what percentage of their
offspring will be white flowered?
10. A white flowered plant is crossed with a plant that is
heterozygous for the trait. What percentage of the
offspring will have purple flowers?
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.

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.

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.
