There are two alleles in a population that influence a specific attribute. Using the letters "A" for the dominant allele and "a" for the recessive allele. A allele frequency is 0.7, whereas frequency of allele is 0.09.

The frequency of the A allele is 0.7, or 70%, since homozygous dominant (AA) genotypes account for 70% of the population. Similarly, since homozygous recessive (aa) alleles make up 9% of the population, we can infer that the frequency of the recessive allele, a, is 0.09, or 9%.

The formula 2pq = frequency of heterozygotes, where p is the frequency of the A allele and q is the frequency of the an allele, can be used to determine the frequency of the heterozygous genotype (Aa).

We know that the frequency of heterozygotes is 0.21, or 21%.

Plugging in the known values:

2 * 0.7 * q = 0.21

Solving for q:

q = 0.15

So, the frequency of the A allele is 0.7, and the frequency of the a allele is 0.09.

It is true that many people believe alfred kinsey's work was responsible for a moral breakdown in the united states.

Alfred Kinsey delivered the Kinsey Report, the biggest documentation of sexuality in the US at the hour of its publication.Analyze the effect of Kinsey's investigation of sexuality connected with how it changed the public's view of sexuality and how individuals are physically mingled.

Kinsey's report was stunningly effective. The two books together sold more than 750,000 duplicates and were converted into thirteen dialects. They might be viewed as probably the best and powerful logical writing of the 20th 100 years. The reports are related with a huge change in open impression of sexuality. A simple ten years after the reports were distributed, the main oral preventative was presented and the sexual upset started. The sexual upheaval was a social development from the 1960s to the 1980s that expanded acknowledgment of sex beyond marriage.

I think that since it lives on the ocean floor, at the deepest of the ocean. So anyway, the fin on the Eurypterids is still necessary but not that much, since they live on the ocean floor. Their movements mostly on the ocean floor. So fin would not help them "stick" to the floor. Also there are still gravity acts on the Eurypterids and the feet would help them move faster. Hope this helps.

Answer: A change to the DNA sequence may or may not change the functionality of the protein, make an inactive protein, or prevent production of the protein.

Explanation: NO SEQUENCE SHOWN, but generally

A gene codes for a protein. A change in one nucleotide (single nucleotide polymorphism - SNP) can have several different consequences. The deletion or insertion of a nucleotide also has consequences

The protein-making part of the gene is organised into codons - groups of three nucleotides who sequences make up the genetic code. Changes may have any of these consequences for the protein:

1. No consequence: there are redundancies in the code and an SNP may not change the meaning of the codon, especially if it is the third nucleotide

Example: CGT --> CGA  these both code for serine, so no change

2. No consequence: an SNP may change the amino acid, but if this is not at a critical part of the protein and/or the amino acids have similar properties it will not affect the end product

Example: ACT --> CCT = isoleucine --> leucine

3. An SNP affects protein folding or the active site. This can alter or prevent protein function

Example: GAG --> GTG = glutamic acid --> valine

leads to sickle cell anaemia if both alleles affected

4. An SNP may prevent completion of the protein. STOP codons tell the reading mechanism the process is complete. If this happens during the process, the incomplete fragment is removed. If the revers occurs, reading will continue until another STOP codon adding additional structure thar will interfere withprotein function.

Example: TAT --> TAG = thyrosine --> STOP codon

5. Insertions and deletions can also disrupt protein formation, by changing the reading frame. The transcription process relies on having a start point, so that codons are read from that point (the reading frame). Adding or removing alters the reading frame so that codons are read incorrectly

Example (start)TTCATCGAGTATCGTACA...codes for phe-ile-glu-tyr-arg-thr

suppose the second C is deleted

the reading frame becomes (start)TTCATGAGTATCGTACA.

which reads as phe-met-ser-ile-val- , a very different sequence.

Answer:

The crane has a sharp and pointed beak adapted for catching and grasping prey. The sharp beak allows the crane to effectively stab and pierce its prey, such as fish, frogs, or small animals. The pointed shape helps the crane to accurately target its prey and secure a firm grip.

On the other hand, the duck has a flat beak, which is better suited for its specific feeding habits. Ducks are primarily filter feeders, and their flat beak enables them to sift through water or mud to collect small organisms, insects, and plants. The flat beak acts like a sieve, allowing the duck to strain out food particles while retaining water.

The difference in beak shape between the crane and the duck reflects their distinct feeding strategies and ecological roles. Each species has evolved its beak shape to optimize its ability to capture and consume the specific types of food sources available in their respective habitats.

The true statement is that the objects are different substances because their densities are different.

Density is an intrinsic property of matter. It does not depend on the amount of substance present. It is a characteristic of substances. If two substances are the same, they must have the same density.

Considering the information presented here, the cube and the marble are different materials hence they have different densities.

In order to increase the permeability of the cell membrane.

Explanation:

A genetic engineerer apply jolts from electricity or high heat to bacterial cell walls during transformation in order to increase the permeability of the cell membrane. Increasing permeability of the cell membrane allows the genetic engineerer to insert the desired chemicals, drugs, or DNA into the cell. If she did not increase the permeability of the cell, no or less materials pass through the membrane and there is less chance of having transformation.

Enzymatic activity is affected by pH and temperature. A) a- 6 pH. b- affect the whole molecule structure, and the proteins functions. B) a- 45ºC. b- The enzyme denaturalizes and its functions are affected.

Enzymes, like all proteins, are polypeptidic molecules. They need to get an accurate tridimensional structure to accomplish their functions. There is a limited temperature and pH level at which they lose that structure and denaturalize.

The most accurate configuration for the best catalytic performance depends on the charge of the lateral chains and the environmental pH.

Enzymes have ionizable chemical groups in the side chains of their amino acids. Depending on the environmental pH, these groups will have a positive, negative, or neutral charge. There is an optimum pH level at which enzymes get the best configuration to accomplish their functions.

Most enzymes are sensitive to any change in pH, which might drastically affect their activity. So every enzyme has its optimum pH level, and any slight deviations will cause the enzyme denaturalization, hence, its activity loss.

In general, the increase in temperature accelerates chemical reactions.

The temperature at which the enzymatic activity is the highest is known as the optimum temperature.

⇒ When the environmental temperature is lower than the optimum, there is a slow enzymatic activity.

⇒ When the temperature exceeds the optimum point, the enzymatic activity sharply decreases. It denaturalizes the enzyme. Over this level, the reaction velocity is counteracted by the loss of the catalytic activity due to denaturalization. Enzymatic activity decreases until it completely annulates.

Graph A:

a) pH optimum: 6 aproximately.

b) Outside the pH optimum, the enzyme does not function because the lower or higher levels of pH affect side chains by changing the ionized state of amino acids, which alter the bonds that keep the stable molecule structure. Under these situations, the molecule loses its functions.

Graph B:

a) Optimum temperature: 45ºC aproximately.

b) At extreme temperatures the enzyme denaturalizes and the molecule does not get to accomplish its functions.

The organism described that can cause illness and death in humans, reproduces asexually, and is among the simplest of living things, is a bacterium.

Bacteria are single-celled microorganisms that can be found in various environments, including soil. They are characterized by their simplicity of structure and lack of a nucleus or membrane-bound organelles.

Certain species of bacteria are pathogenic and have the ability to cause diseases in humans. Examples include bacteria like Escherichia coli (E. coli), Salmonella, and Staphylococcus aureus.

These bacteria can enter the human body through various means, such as contaminated food or water, and can cause a range of illnesses, from mild to severe, and even life-threatening conditions.

Bacteria have the ability to reproduce asexually through a process called binary fission. In this process, a single bacterium divides into two identical daughter cells, allowing for rapid multiplication of the population.

It is important to note that while bacteria can be harmful, many bacteria are beneficial or have neutral effects on humans and play crucial roles in various ecological processes and human health.

Viruses spread by infecting cells and replicating within them. There are several ways that viruses can spread from one person to another:

Direct contact: Viruses can be spread through direct contact with an infected person, such as through shaking hands or hugging.

Indirect contact: Viruses can also be spread through indirect contact, such as by touching a surface or object that has been contaminated with the virus and then touching one's face, mouth, or eyes.

Respiratory droplets: Some viruses, such as the virus that causes COVID-19, are spread through respiratory droplets that are produced when an infected person talks, coughs, or sneezes. These droplets can land in the mouths or noses of people who are nearby or be inhaled into the lungs.

Sexual contact: Some viruses, such as HIV and herpes, are spread through sexual contact.

Overall, viruses can spread through a variety of means, and the specific method of transmission can depend on the specific virus and the mode of infection.

False, ribosomes are not involved in transport of things around the cell.

What are ribosomes?

Organelle involved in transportation: ENDOPLASMIC RETICULUM

Similar to how a city's road network enables mobility within it, the endoplasmic reticulum is a network of tube-like passageways via which proteins from the ribosomes can be transported.

Endoplasmic reticulum is another name for it. There are two types: RER and SER. Rough ER and Smooth ER are abbreviations for respectively. Ribosomes are affixed to rough ER, aiding in the synthesis of proteins. Cells use ERs for a variety of purposes. One of their main jobs is to serve as a transport route. The endoplasmic reticulum membrane is used to transport secretory proteins, primarily glycoproteins.

Hence, endoplasmic reticulum is involved in transport and not the ribosomes

FALSE. X-rays and gamma rays are examples of ionizing radiation, but they do not cause the formation of thymine dimers.

Thymine dimers are a type of DNA damage that occurs when two adjacent thymine bases in DNA become covalently linked to each other, forming a dimer. This can occur when DNA is exposed to ultraviolet (UV) radiation from the sun or other sources. The formation of thymine dimers distorts the normal structure of DNA, causing errors during DNA replication and transcription, which can lead to mutations, cell death, or cancer. Thymine dimers are one of the most common types of DNA damage caused by UV radiation, and they play a significant role in the development of skin cancer.

UV radiation has a shorter wavelength than X-rays and gamma rays and is non-ionizing, meaning it does not directly ionize molecules. Instead, UV radiation causes chemical reactions in molecules, including the formation of thymine dimers in DNA.
