Answer:
Repetitive DNA sequences "minisatellites." The two major uses for the information provided by DNA-fingerprinting analysis are for personal identification and for the determination of paternity. DNA fingerprinting is based on DNA analyzed from regions in the genome that separate genes called introns.

Genetic drift and natural selection can both be mechanisms of evolution. However, they are very different mechanisms. Explain how genetic drift is different from natural selectio
Answer:
Explanation:
Natural selection is the survival of individual organism due to the difference in phenotype. It serves as a basic for evolution as the different heritable characteristics in an individual is due to natural selection. Natural selection acts on the phenotype of the individual which is the visual observance while Genetic drift is the change in frequency of an allele that already exist in a population. This could lead to the allele being selected against and if very small can be lost with time.
In the previous activity, you chose an animal that interested you and listed three examples of innate behavior and three examples of learned behavior for that animal. Now research what, if any, courtship and mating rituals this animal has. Explain why you think it has or doesn’t have these behaviors.
Answer:
what grade
Explanation:
Courtship and mating rituals are diverse and can vary greatly among different animal species. They are typically involved in attracting mates, establishing pair bonds, and ensuring successful reproduction.
1. Courtship and Mating Rituals Exist: Many animal species have elaborate courtship and mating rituals. These behaviors can serve various purposes, such as displaying fitness and attractiveness to potential mates, establishing territory, or demonstrating parental abilities.
2. Absence of Courtship and Mating Rituals: Some animal species may not exhibit elaborate courtship or mating rituals. This can occur in species where mating opportunities are abundant or where the reproductive process is straightforward without the need for elaborate displays.
The presence or absence of courtship and mating rituals can depend on various factors, including ecological pressures, social structure, reproductive strategies, and evolutionary history of the species. Different species have evolved different strategies to maximize their reproductive success, and these strategies can manifest as complex courtship rituals or simpler methods of attracting mates.

Look at the following mutation: AUG-GUC-CCU-AAA → AUG-AGU-CCC-UAA-A. The base A was inserted following the start codon AUG. Describe how this mutation affects the encoded amino acid sequence.
Answer: Non sense mutation took place over here.
Explanation:
Mutation took place over here where, the base A was inserted in place of the start codon AUG.
This states that the last codon will code for a stop signal instead of amino acid.
This is a type of non sense mutation when the ribosome is stopped from reading a stretch of mRNA because a stop codon is present over there.
The original set of codon is replaced by the stop codon and the protein synthesis is stopped.
When there is an alteration in the genetic bases of codes that can lead to modification in the phenotype or the genotype of an organism is called a mutation.
The type of mutation that occurred in the given sequence is a non-sense mutation.
The mutation can be explained as:
The mutation changed the reading frame of the triplets from the second place after the AUG or the start codon.The last codon in the unmutated sequence AAA was for lysine (lys) but in the mutated sequence is changed to UAA (stop codon) which codes for the termination of the chain.The mutation in stop codons are called non-sense mutation and now it will signal for termination instead of coding for another amino acid.When the process of translation gets terminated and the ribosomes stop translating due to mutation then it is called a nonsense mutation.Therefore, the process will terminate due to replacement by a stop codon.

Hospital patients often receive medications, nutrients, and water intravenously (IV), which means they are injected directly into the patient’s veins through a needle. IV fluid is not pure water, but is instead a saline solution (water containing NaCl). What do you think is the appropriate NaCl concentration for IV fluid? Why?
Answer:
The answer to the following question is given below.
Explanation:
Saline includes 9 g NaCl dissolved in 1 liter of distilled water utilized primarily for sick people with moisturization.
This NaCl concentration has been presumed to be the physiologic concentration necessary for the restoration of vitamins and minerals by the body to control a suitable osmotic balance.
NaCl is mainly used to cover up the salt missing. In order to help nerves function properly, our bodies do require sodium.
The explanation regarding appropriate NaCl concentration for IV fluid is explained below:

What is the difference between native and nonnative species
Answer:
Native plants are those plants which occur naturally in a region. A non-native is one that does not.
Explanation:
For example, soybeans, kiwi fruit, wheat, honey bees, and all livestock except the American bison and the turkey are non-native species to North America.
Answer:
Native species are naturally present in an area. ... Non-native species do not cause environmental or economic harm. An important, not-to-be-missed distinction between non-native species and invasive species is that non-native species do not disrupt the natural functions and processes of our native ecosystems.

a video that shows penguin species that have different mating dances
The reproductive isolation is the factor which allows the species to evolve and form a new species, therefore, this factor is used to describe a species.
The reproductive isolation refers to a mechanism in which the species are isolated to not interbreed with the individual of other species. The reproductive isolation could be due to behavioural, psychological, physical or genetic differences. evolved as an adaptation.
In the given cases, the penguin species which shows different mating dances is considered to be reproductively isolated as the different dance rituals evolved as behaviour to prevent them from mating.
Thus, the selected option is correct.
A video that shows a large river that has penguin populations on both sides would make the best project. So, the correct option is A.
What is Population?A population is defined as the complete set of individuals, whether that group includes a nation or a group of people with a common characteristic which is the pool of individuals from which a statistical sample is drawn for a study. .
It is described as a unit of biological community made up of a permanent group of an interbreeding individual of a species found in a space or geographic region at a particular time. Population are of three types of population pyramids created from age-sex distributions-- expansive, constrictive and stationary.
Thus, a video that shows a large river that has penguin populations on both sides would make the best project. So, the correct option is A.

In photosynthesis, plants use _______ and release ________. *
A. carbon dioxide, oxygen
B. oxygen, carbon dioxide
Answer:
A. carbon dioxide, oxygen
Explanation:
Photosynthesis is a process that certain organisms (plants, algae and some bacteria) undergo to produce their own food. The equation for photosynthesis is:
water + carbon dioxide + light energy —> glucose + oxygen
In photosynthesis, the plant takes water, carbon dioxide and light energy from the sun and turns it into glucose (sugar, or the food) and oxygen.
Therefore, the correct answer is A. carbon dioxide, oxygen. The plant will use carbon dioxide and then release oxygen as a waste product.
