Explanation:
Answer: The correct answer is C) The public is upset with the farms’ unnatural farming practices.
Explanation: This answer is confirmed correct.
Corporate farms are geared toward cost savings and making a profit, so they do not typically invest in protecting natural resources and using better processes for the environment.
What is the overall impact of harvesting non-renewable resources such as oil and methane.
The harvesting of non-renewable sources can generate impacts such as huge volumes of rock and soil from extractions being dumped in other locations, affecting the local ecosystems. The sites in which land is being mined, the quality of the soil decreases over time, getting really poor and sometimes even polluted by chemicals, polluting nearby water as well. Drilling and extracting natural gas can cause methane to leak, and methane is a potent greenhouse gas, rising temperatures and changing weather patterns. There are many impacts that can be caused by the use of non-renewable resources, and as we can see they start from its harvest and extraction.
Continental drift. Much more modern day evidence has come to light to support this theory. Early on, Alfred Wegner cited the geological set of continental coast lines; it was noted that the coast lines of south America and west Africa seem to match up, today we have more evidence. Using the graphic in the statements below, elaborate on how the fossils remains of mesosaurus, A freshwater crocodile like reptile that lived between 286 in 258 million years ago, provide support for the theory of continental drift. Which statement does not apply.
I NEED THIS FAST!!! CORRECT AND FIRST ANSWER GETS BRAINLIEST ANSWER!!!!!!
Answer: The correct answer (the statement that does NOT apply) is A. Mesosarurus swam from one continent to the other in breeding pairs.
Explanation:
The remains of Mesosaurus (a freshwater crocodile-like reptile living between 286 and 258 million years ago) have been found in Southern Africa and Eastern South America. Scientists have proven that Mesosaurus was not capable of swimming between the continents, so the presence of their fossils on two continents has proven the theory of continental drift. There is additional evidence that supports continental drift, where the two continents were connected.

what is the net charge on the protein: glu-ala-ser-lys-val-arg-phe-ile-his at a ph value of 6.5?
The net charge on protein glu-ala-ser-lys-val-arg-phe-ile-his having pH 6.5 is 0
Out of all given amino acids all of them are triprotic except Glutamic acid, Lysine, Arginine and Histidine , hence only these amino acids participate in net charge of protein.
Writing the rest protein chain-
glu-lys-arg-his
Writing the pka value for all,
pKa for NH₃⁺ = 9.62
pKa for COO⁻ =2.34
pKa for glu =4.25
pKa for lys=2.18
pKa for arg=12.45
pKa for his= 6
Given pH= 6.5 which is greater than the pKa of his , glu ,lys and COO⁻, so all of them got deprotonated.
So, charge will be,
-1( COO⁻) +1(NH₃⁺)+1 ( NH₃⁺ of arg) - 1(COO⁻ of glu)
= 0
So, the net charge will be zero for the given sequence of amino acid of the protein.

These various variations of a gene are referred to as alleles. For instance, two alleles may occur at one specific locus, one of which codes for the cytosine base and the other for the thymine base. One copy of the human genome is inherited from each parent. We are hence referred to as diploid organisms.
What is Allele Frequency ?The relative frequency of an allele at a certain locus in a population, represented as a fraction or percentage, is known as gene frequency or allele frequency. The percentage of chromosomes in the population that carry that allele relative to the whole population or sample size is what is being discussed.
The frequency of an allele in a population is referred to as its allele frequency. It is calculated by dividing the number of gene copies by the number of times the allele occurs in the population. All the copies of every gene in a population make up the gene pool of that population.
What is Allele ?Leading textbooks on genetics and evolution define an allele as a different variation of the same sequence of nucleotides at the same location on a long DNA molecule.

An illness caused by a certain virus includes fever, rash, joint pain, red eyes, and headache.
The virus is transmitted to people by infected mosquitoes. Symptoms quickly occur within
three to twelve days after contracting the virus. There is no vaccine for this virus.
Which description best explains the reproductive cycle of this virus?
A Lytic, because the virus is transmitted by mosquitoes
B Lysogenic, because there is no way to vaccinate against it
C Lytic, because of the quick incubation time
D Lysogenic, because the virus causes a fever
Lytic, because of the quick incubation time explains the reproductive cycle of the virus.
What is lytic cycle?
One of the two viral reproduction cycles, the other being the lysogenic cycle, applies to bacterial viruses or bacteriophages. The infected cell and its membrane are destroyed as a result of the lytic cycle. Virulent phages are bacteriophages that only utilise the lytic cycle (in contrast to temperate phages).
Although the lytic cycle's final result is the generation of new phage offspring and the death of the host bacterial cell, this is a multistep process that requires careful synchronisation of physical processes and gene transcription. The phage must locate a receptive and appropriate host bacterial cell that it can adhere to. The host genome is destroyed after the introduction of phage genetic material into the cell, and the phage then uses the host cellular machinery to manufacture copies of its own genome and synthesise the structural elements. Before the host cell lyses and the phage progeny is discharged into the surrounding environment to find new target cells, new phage are assembled.
Here we can see that symptoms quickly occur within three to twelve days after contracting the virus.

the roots of the trees bind the topsoil altogether and it prevents the wind and water to carry away the soil. When there is deforestation the binding of the soil particles is greatly affected, and the most fertile part of the soil (the top layer) can be carried away by floods for example. This makes the soil infertile eventually leading to desertification.

Why does evolution always lead to more advanced species?
General category: Biology.
Sub-category: Evolution.
Topic: natural selection
Introduction:
According to Darwin's theory of evolution, those members of the population with less adapted characteristics (as determined by their environment) are more likely to die. So those members with better-adapted characteristics are more likely to survive.
Explanation:The sentence "species are more advanced due to evolution" or equivalently "evolution always leads to more advanced species" is false.
According to the theory of evolution, organisms that are more adapted to certain environments survive and pass their genes from generation to generation. However, when environmental conditions change, these characteristics may not be advantageous for survival in the space where these species are found, and they may die.
An example of this is polar bears. Their fur is white, which gives them an advantage when hunting their prey since these bears can go unnoticed in the snow, which is white. However, due to global warming, this feature is no longer an advantage in certain regions where the ice has melted excessively and prey can more easily see this great hunter. However, this does not imply that the polar bear is more advanced or less advanced. It implies that the conditions of the environment influence the conditions of survival and that evolution is guided by random or provoked changes in the environment of organisms.
We can conclude that the correct answer is:

While a tendon ties a muscle to a bone, acting as an anchor for the muscle, a ligament joins two bones. A ligament keeps the shin and foot bones (tibia and fibula with the talus) together at the ankle joint, while the Achilles tendon, for instance, connects the calf muscles to the calcaneus (heel bone).
