Is a silent mutation missense?
A silent mutation occurs when a mutation is not changing any amino acid coded for that codon. so, they are also known as missense mutation.
In general, Nucleotide substitutions may lead to no change in the protein sequence which known as silent mutations. so , we can say that a silent mutation is a mutation that occurs within the DNA sequence, but they do not alter the amino acid sequence. These mutations takes place in an introns, that is spliced before translation.
Hence, example may include Single nucleotide substitutions they are not involved in changing any of the amino acid sequence so termed as silent polymorphisms. Mutation in these base pair will also not change the function of the protein.

Which of the groups of organisms in the food web would most likely have accumulated the largest concentration of long lasting chemical pollutants in their bodies
The question is incomplete, the complete question is shown in the image attached
Answer:
F
Explanation:
The image shows a food web. A food web shows all the possible feeding relationships in an ecosystem.
We have to know that the concentration of chemical pollutants increases in organisms as you move up the food web. Higher level organisms tend to accumulate a greater concentration of chemical pollutants than the organisms that are lower in the food web.
Thus, the organism which appears at the highest level of the food web shown in the image will most likely have accumulated the largest concentration of long lasting chemical pollutants in their bodies.

Explanation:
Gulls, or colloquially seagulls, are seabirds of the family Laridae in the suborder Lari. ... Most gulls are ground-nesting carnivores that take live food or scavenge opportunistically, particularly the Larus species. Live food often includes crustaceans, mollusks, fish, and small birds.
Why do cancer cells divide and multiple uncontrollably?
Answer:
Most cancer-causing DNA changes occur in sections of DNA called genes. These changes are also called genetic changes. A DNA change can cause genes involved in normal cell growth to become oncogenes. Unlike normal genes, oncogenes cannot be turned off, so they cause uncontrolled cell growth.
Is the claim, "Despite not being a plant, you get your energy from the sun." accurate?
Write a paragraph explaining your reasoning.
Answer:
Yes (kind of), because even though we do not use the sun as directly as say plants, we still rely on the sun on a daily basis, however we don't necessarily get our energy from it, like plants do.
The sun produces light as well as heat, also known as solar energy. This makes it possible for life to exist on Earth, and we can use solar energy to power a wide variety of useful things, however sun/solar energy is not the only way to get electricity.
As we know, plants need sunlight to grow, although humans don't grow by being exposed to sunlight, sunlight helps grow plants which animals, including humans, need for food as well as oxygen they produce.
Most livestock we eat, cows for example, need plants to survive and many people eat meat, and even if you don't you'd eat plants which, once again, need sunlight to grow. Also, without heat from the sun, Earth would freeze.
OVERALL...
It's kind of like a chain, we get our energy from things that get their energy directly from sunlight. A short answer would be yes, but it's not quite as simple as that.
I hope this helps, hopefully you can use it to formulate an answer of some sort.
Describe in one paragraph the importance of proteins and amino acids. (5-8) sentences
Answer:
Proteins are the building blocks of life. Every cell in the human body contains protein. The basic structure of protein is a chain of amino acids.
Explanation:
Your body needs protein to stay healthy and work the way it should. Protein is also a critical part of the processes that fuel your energy and carry oxygen throughout your body in your blood.
Amino acids are required for the synthesis of body protein and other important nitrogen-containing compounds, such as creatine, peptide hormones, and some neurotransmitters. Although allowances are expressed as protein, the biological requirement is for amino acids.

Explain how natural selection could lead to a change in allele frequency leading to a change in the color of the frogs.
Answer:
Due to increasing the survival.
Explanation:
The natural selection causes a change in allele frequency leading to a change in the color of the frogs because the colour of the frog helps it in hiding from predators. The population of that frog specie increases which has the ability to hide from the predators in that environment while on the other hand, the population of frog decreases which can easily be seen by the predator due to its colour so this change in allele frequency will leads to natural selection.
PLS HELP 20 PTS What other factors might cause individuals in this antelope herd to emigrate
Answer:
When you think about it - this is a similar case that happens in our species as well. You have groups of people who want to emigrate to different countries in hope for better grassland.
They emigrate but are immigrants from the perspective of the grassland where they will be.
The other factors that might cause individuals in this antelope herd to emigrate are immigration, increasing birth rate, and decreasing death rate.
What is emigration?When an animal emigrates, it's because its habitat is no longer ideal for it and it needs to move to a new location with a better habitat. Animals that migrate or emigrate never go back to the place they were originally from.
This is a similar situation to one that occurs in our species. There are various groups of people who want to immigrate to various nations in search of better grasslands. From the perspective of the grassland where they will be, they migrate but are immigrants.
Therefore, Immigration, a rising birth rate, and a declining death rate are some additional factors that could result in members of this antelope herd leaving the group.

Why does an increase in number of cells cause growth?
Growth in all organisms occurs through the process of mitotic cell division. Cell division is the process of dividing old cells to form new cells, thereby increasing the number of cells needed for growth and various other activities in the body. It is a major and regular process essential to all life.
During mitosis, cells divide to form two identical daughter cells. All cells undergo mitosis and in this way the number of cells in the body increases and the organism grows.
Body tissue grows by increasing the number of cells that make it up. Cells in many tissues of the body divide and grow very rapidly into adulthood. As we grow, many cells mature and specialize in specific tasks in the body.

How is fumigant different from pesticides ? Name one natural substance which can be used in place of fumigant
Fumigants are chemicals that are used to kill pests by releasing a gas that penetrates into areas where pests may be hiding. These chemicals are often used to control pests in large, enclosed spaces such as grain storage facilities or ships.
Pesticides, on the other hand, are chemicals that are used to control, repel, or kill pests. Pesticides can be applied in various forms, such as liquids, granules, or sprays, and can be used to control pests on crops, gardens, and other outdoor areas.
One natural substance that can be used in place of a fumigant is thyme. Thyme is a herb that contains a chemical called thymol, which has insecticidal properties. Thymol can be used to control a variety of pests, including mites, insects, and nematodes. It can be applied in various forms, such as a spray or a dust, and is considered to be less toxic and safer to use than synthetic fumigants.

An organism can pass a gene mutation to its offspring if the mutation occurs in gamete as a result of sexual reproduction .
A mutation can be transmitted down to an organism's progeny if it happens in a germ-line cell (a cell that will develop into gametes, such as egg or sperm). This implies that the mutation will be present in each and every cell of the growing embryo. A parent's genetic mutation may be carried on to their child through their egg or sperm.
Throughout a human's life, these inherited mutations are prevalent in almost every cell of their body. Cystic fibrosis, haemophilia, and sickle cell disease are examples of hereditary mutations. Large-scale evolution only takes into account mutations that can be passed on to future generations. These are known as germ line mutations and they happen in reproductive cells such as eggs and sperm. Environmental factors contribute to mutations.

How can people exercise good and wise Dominion over the process of photosynthesis for God's glory
Wise dominion over the process of photosynthesis can be exercised in such a way that all the people and animals can benefit from it and we can use it correctly.
Photosynthesis is a process that plants and other organisms use to convert light energy into chemical energy that can then be released to fuel the organism's activities via cellular respiration. Some of this chemical energy is stored in carbohydrate molecules, such as sugars and starches, which are formed by the reaction of carbon dioxide and water.
Photosynthesis is performed by the majority of plants, algae, and cyanobacteria; these organisms are known as photoautotrophs. Photosynthesis is responsible for producing and maintaining the oxygen content of the Earth's atmosphere, as well as supplying the majority of the energy required for life on Earth.

How might the genetic content of these change by the time tetrads have aligned at the metaphase plate during metaphase I of meiosis
Sister chromatids are chromosomal chromatids that are identical to one another. They are normally produced by the DNA molecule of a single chromosome replicating in a semi-conservative manner.
They are therefore "photocopies" of the original parent chromosomes that have been joined at the Centromere. They share the same gene and allele makeup, making them completely identical.
There are, however, slight variations between the two identical sisters due to mutation from replication errors and alterations in the length of telomere repeats.
In metaphase I, tetrads arrange themselves along the metaphase plate whereas homologous pairs orient themselves randomly. During anaphase I, homologous chromosomes separate and centromeres deteriorate.
In telophase I, chromosomes move to opposite poles, and in cytokinesis, the cell splits into two haploid cells.

What is Mendel's law of segregation What do we called his factors today and where are they located?
The two alleles for a particular gene separate throughout the development of gametes, according to Mendel's law of segregation, leaving just one allele for each gamete. This indicates that just one allele from each parent is passed on to the offspring for a particular gene when the gametes combine at fertilization.
Mendel's factors have come to be known as genes. A gene is a section of DNA that contains the instructions for making a particular protein, which in turn defines a certain trait.
Chromosomes, which are situated in the nucleus of cells, are where genes are found. Each gene in diploid organisms like pea plants has two alleles, one of which is inherited from each parent.
Mendel's law of segregation explains Mendel's observed inheritance of single traits in his pea plants and it is the basis for Mendel's Punnett square, a tool that is widely used today to predict the possible outcomes of genetic crosses.
