What kinds of diseases can vaccinations prevent?
genetic diseases only
bacterial diseases only
viral diseases only
any infectious disease
Any infectious disease (genetic, bacterial, and viral) can be prevented by vaccinations. Therefore, option D is correct.
Vaccinations are primarily designed to stimulate the immune system and provide protection against specific pathogens that cause diseases. They work by introducing harmless components of the pathogen, such as inactivated or weakened viruses or bacteria, or their components (antigens), into the body.
This exposure allows the immune system to recognize and mount an immune response against the pathogen without causing the actual disease.

A forensics expert has obtained a sample of human blood from a crime scene. How can DNA fingerprinting be useful for identifying the person who left
the blood at the crime scene?
A by identifying the sequence of nucleotides in the DNA of blood cells
B. by comparing DNA from the blood cells with DNA from suspects
C. by identifying certain genetically controlled traits of suspects, such as eye shape and blood type
D. by comparing karyotypes made from blood cells at the crime scene and blood cells from suspects
Answer:
B - by comparing DNA from the blood cells with DNA from suspects!
Explanation:
DNA fingerprinting is a laboratory technique used to establish a link between biological evidence and a suspect in a criminal investigation.
A DNA sample taken from a crime scene is compared with a DNA sample from a suspect.
If the two DNA profiles are a match, then the evidence came from that suspect. (from www.genome.gov )
Hope this helps! :]
A forensics expert has obtained a sample of human blood from a crime scene, DNA fingerprinting may be useful by comparing DNA from the blood cells with DNA from suspects, which is option B.
What is DNA fingerprinting?DNA fingerprinting is a technique used to identify individuals based on their unique DNA profiles, and by analyzing the sequence of nucleotides in an individual's DNA, forensic scientists can create a DNA profile that is unique to that individual. So to identify the person who left the blood at the crime scene, forensic scientists would analyze the DNA in the blood sample and create a DNA profile, and then find out the criminal based on the DNA fingerprinting.
Hence, DNA fingerprinting may be useful by comparing DNA from the blood cells with DNA from suspects, which is option B.

AUG is the start codon, and UAG, UGA, and UAA are the possible stop codons.
The code on a human mRNA reads AUGCCCUUUAUGGGGUAA.
ges
Which statements are true about this sequence?
Select all that apply.
Protein synthesis cannot start because there is no start codon.
The protein will have only four amino acids.
Two methionine amino acids will be in the protein chain.
The protein will have five amino acids.
Answer:
The correct answer is -
Two methionine amino acids will be in the protein chain.
The protein will have five amino acids.
Explanation:
In protein synthesis, there are mRNA codons made up of the three bases known as triplet codons that form a specific amino acid during translation. There is a specific codon known as the starting codon that is AUG present at the beginning of almost every protein sequence and code for the methionine amino acid. UAG, UGA, and UAA are the stop codons if present at the end of the mRNA sequence and if any of these stop codons are present at the end of the sequence they do not produce any amino acid.
In this case, the mRNA sequence having 6 triplet codons AUG CCC UUU AUG GGG UAA where the first AUG is a start codon and code for the methionine and UAA is a stop codon and do not code for any amino acid therefore, the protein would carry only 5 amino acid and as there are two AUG so it has two methionine.
Answer:
Two methionine amino acids will be in the protein chain.
The protein will have five amino acids.

name the four major groups in the plant kingdom and discuss the major evolutionary trends across the groups
Answer:
The kingdom Plantae consists of four major plant groups on land: bryophytes (mosses), pteridophytes (ferns), gymnosperms (cone-bearing plants), and angiosperms (flowering plants). Plants may be categorized as vascular or nonvascular. A vascular plant has tissues for transporting water or sap. Nonvascular plants do not.

chemicals

light
sound waves
Answer and I will give you brainiliest
Answer:
chemicals
Explanation:
The nose and the tongue are two of the five sensory organs (others being skin, eyes, ears). These organs contain certain cellular structures called SENSORY RECEPTORS, which respond to different stimulus in the environment.
Nose and tongue are two organs that possess a type of sensory receptor called CHEMORECEPTORS. Chemoreceptors are receptors that respond to chemical stimuli. In other words, the receptors in the nose and tongue are stimulated by chemical substances e.g. food chemicals for TONGUE, chemicals in air for NOSE.
advantages and dis advantages of asexual reproduction in plants
Explanation:
Advantages Of the asexual reproduction
The organism that reproduces asexually has the ability to take many different extensive forms that allow asexual reproduction to succeed in various environments?
The asexual reproduction is only performed in the organisms that often stay in one place, It does not need mobility, So, most plants have a great ability to create their offspring as this process doesn’t need to move to another place.
Asexual reproduction has a rapid increase of offspring which is very helpful in producing lots of offspring, It lets the plants make lots of offspring effectively which will help them in increasing their genes.
Disadvantages Of Asexual Reproduction
Most organisms that only perform the asexual reproduction process have less chance to adapt to the changes of the environment as they need stable environments.
Only one parent plant is required for the asexual reproduction, the new plants are identical to the parent so that good features will always be passed on, the chromosomes and genes of the parent will be copied, So, there will be genetic defects or the mutation in the offspring with no exception.
The asexual reproduction does not have the genetic diversity, there is less variation produced with the offspring, and the organism becomes less adapted to certain environmental changes, the entire communities will not be adapted to the harsh environment.
The asexual reproduction usually leads to struggle for the existence as well as the overcrowding, and the main distinction of asexual reproduction from the sexual reproduction is that there is no need for two parents as well as special cells to reproduce.

Under which of these conditions would scientists use the polymerase chain reaction (PCR) before they analyze a DNA sample?
A
The DNA sample comes from a bacterium or virus,
B. The DNA sample has been cut into fragments by restriction enzymes.
COnly a small amount of the DNA sample is available,
D.
The DNA sample includes regions that are transcribed into mRNA,
Answer: C
Explanation:
A specific DNA segment is amplified via PCR from a complicated combination of starting material, commonly referred to as template DNA, hence option C is correct.
What is the polymerase chain reaction (PCR)?The reaction's simplicity and the relative case of the practical manipulation procedures are what's behind it. The reaction needs some knowledge of the flanking DNA fragment's sequence in order to be amplified.
Taq polymerase is the name of the heat-tolerant bacterium from which the DNA polymerase normally used in PCR was derived (Thermus aquaticus). T. aquaticus resides in hydrothermal vents and hot springs.
The primers are used in accordance with the sample or target DNA. The procedure, which entails numerous cycles in which copies are created, likewise uses DNA and Taq polymerase.
Therefore, the three fundamental phases are "denaturation," "annealing," and "extension."

Answer:
B. Sun.
Explanation:
The carbon cycle can be defined as the cycle in which carbon atoms travel from the atmosphere to earth and back to the atmosphere. As carbon is the source through which all life on earth exists.
The source of the carbon cycle is solar energy. During the process of photosynthesis, it is the sun that plays an integral role in taking carbon dioxide from plants.
