Answer:
causes of Air pollution. 1. Burning of Fossil Fuels: Sulfur dioxide emitted from the combustion of fossil fuels like coal, petroleum and other factory combustibles is one the major cause of air pollution. Pollution emitting from vehicles including trucks, jeeps, cars, trains, airplanes cause immense amount of pollution ...Gases like Sulfur dioxide and nitrogen oxide can cause acid rain. Water pollution in terms of Oil spill may lead to death of several wildlife species. 2. Human Health : The decrease in quality of air leads to several respiratory problems including asthma or lung cancer.

Variables effecting enzyme function- Amoeba Sisters video recap Enzymes
4.?
5.?
Answer:
Im not sure sorry.
Explanation:
Proteins known as enzymes serve as catalysts in biological processes, accelerating the pace of chemical reactions. Several environmental conditions have an impact on an enzyme's effectiveness. The most crucial element is temperature.
The ideal temperature range for enzyme activity is typically between 30 and 40 degrees Celsius. The enzyme may lose its structure and, thus, its ability to perform when temperatures over this range cause it to become denatured. Another key aspect is pH; enzymes function best within a specific pH range.
The ionisation of the enzyme's amino acid residues can be impacted by pH, which will change the enzyme's structure and activity. Finally, the concentration of the substrate and the enzyme can influence the rate of the reaction along with the temperature.

Please help me with bio
Answer: C or D
Explanation:
A group of scientists were using CRISPR to treat a mouse with cystic fibrosis, a disease caused by a defective Cl- channel protein called CFTR. The most common cause of cystic fibrosis in humans is the absence of a phenylalanine, an amino acid, in the CFTR protein, which prevents CFTR from achieving the correct 3-D structure.If the scientists wished to repair this mutation, how would they alter the mutated CFTR gene before using CRISPR to insert the DNA into the mice
Answer:
they can insert the codon that encodes phenylalanine by CRISPR-Cas mediated homology-directed repair
Explanation:
The CRISPR (clustered regularly interspaced short palindromic repeats,)-Cas (CRISPR-associated protein) is a versatile technology for genome editing which has been developed by adapting a natural defense mechanism found in prokaryotic organisms. The CRISPR-Cas genome editing tool can be used to edit DNA sequences in eukaryotic genomes (for example, in human genomes) and thus restore gene function (in this case, the CFTR gene function). The system consists of a Cas protein that cleaves the DNA at specific genomic sites and a single guide RNA (sgRNA) that guides the Cas protein at specific genomic locations. CRISPR-Cas mediated homology-directed repair refers to the process where Cas cuts the DNA to triggers the homologous recombination (HR) DNA repair pathway, by which it is possible to insert new genetic sequences at specific genomic sites (in this case, the codon that encodes phenylalanine within the specific CFTR gene).

Why is the sequence of amino acids important to protein function?
A)
The sequence of amino acids doesn't have an effect.
B)
Amino acids can only be combined in a specific order, otherwise the bonds will fall apart.
C)
The order of amino acids determines the shape a protein will take.
D)
The order of the amino acids can be read like a code to assemble DNA.
The order of amino acids determines the shape a protein will take. The correct option is C.
What is amino acid?Organic compounds that contain both amino and carboxylic acid functional groups are known as amino acids.
Although hundreds of amino acids exist in nature, the alpha-amino acids that comprise proteins are by far the most common. The genetic code contains only 22 alpha amino acids.
Amino acids, also known as protein building blocks, are compounds that play a variety of important roles in your body.
They are required for vital processes such as the synthesis of proteins, hormones, and neurotransmitters. Protein-rich foods, such as meat, fish, and soybeans, are high in amino acids.
Each protein's unique 3-dimensional structure and function are determined by the sequence of amino acids.
The sequence of genes determines the combinations of three DNA building blocks which is nucleotides that basically code for amino acids.
Thus, the correct option is C as it is assemble in such a way to determine the shape of protein.

O Cytokines
What hormone helps plants move toward a stimulus?
O Ethylene
✓ Auxins
O Acids
O Cytokines
Auxin moves to the darker side of the plant, causing the cells there to grow larger than corresponding cells on the lighter side of the plant. This produces a curving of the plant stem tip toward the light, a plant movement known as phototropism. Auxin also plays a role in maintaining apical dominance

The black panther phenotype in jaguars, which is a completely black coat, is thought to be determined by a single gene. If the presence of this phenotype were unrelated to habitat type, but was found to be much more common in populations in Costa Rica relative to populations in Brazil, what would be the most likely explanation for this geographic pattern
Answer:
Due to suitable climate and food availability.
Explanation:
The reason for this geographical distribution is the availability of suitable climate and food. Black panthers live in the hot, dense tropical rainforests environment where there is a lot of food present that is necessary for sustaining the population of black panthers. Black panthers are more common in Costa Rica as compared to populations in Brazil due to climate as well as food availability.
In drosophila, red eyes is the wild-type phenotype. Several different genes (with each gene existing in two or more alleles) are known to affect eye color. One allele causes purple eyes, and a different allele causes sepia eyes. Both of these alleles are recessive to red eye color. When flies with purple eyes were crossed to flies with sepia eyes, all the F_1 offspring had red eyes. When the F_1 offspring were allowed to mate with each other, the following data were obtained:
146 purple eyes
151 sepia eyes
50 purplish sepia eyes
444 red eyes
Explain the pattern of inheritance.
Answer:
9:3:3:1.
Explanation:
The offspring produced with the ratio of 9:3:3:1 in this crossing. In the F1 generation, all the organisms have the dominant allele but when the two F1 organisms are allowed to mate with each other, the highest ratio of offspring i. e. 9 having dominant allele is produced, hybrid organisms are also produced in the ratio 3 and in the last the offspring that have recessive allele is produced having the ratio of 1.
