Mode of Action of the Herbicide DCMU When chloroplasts are treated with 3-(3,4- dichlorophenyl)-1,1-dimethylurea (DCMU, or diuron), a potent herbicide, O2 evolution and photophosphorylation cease. Oxygen evolution, but not photophosphorylation, can be restored by addition of an external electron acceptor, or Hill reagent. How does DCMU act as a weed killer

Answers

Answer 1

Answer:

It acts as a weed killer by blocking photosynthesis

Explanation:

Photosynthesis is important to plants because it is their principal form of energy.

When DCMU is introduced to weeds, what it does is to block or slow down the process of photosynthesis. Carbon dioxide fixation is slowed down causing weeds to die off. DCMU strongly slows down photosystem II. When this is done, lipid and protein membranes would get destroyed and the weed cells would begin to dry and shed off

Over a six-year period, a biologist has collected data about the physical characteristics, behavior, feeding habits and mating rituals of four bird species living in a South American rainforest. At the end of the six-year period, the biologist claims that evidence of evolution is present in two of the four species. Which of the following is most likely to occur when the biologist presents these findings to other scientists?

Answers

Answer:

C Scientists will debate and seek confirmation through additional research prior to accepting the findings as fact.

Explanation:

When a biologist presents evidence of evolution in two of four bird species living in a South American rainforest, it is likely that other scientists will engage in a critical evaluation of the data and conclusions.

What is the importance of evidence?

Scientists may ask questions about the methods used to collect and analyze the data, and may also examine the data themselves to determine the validity of the conclusions. They may also compare the data with other studies and consider alternative explanations for the observed changes in the two species.

Ultimately, the goal of this process is to determine whether the evidence supports the conclusions about evolution in the two bird species. If the evidence is found to be sound and the conclusions are supported, the findings may be published in a scientific journal and become part of the scientific literature. However, if the evidence is not robust or the conclusions are not supported, the findings may be revised or rejected.

In conclusion, the presentation of the findings is likely to lead to a critical evaluation and scientific discussion among other biologists, which can help to establish the validity of the evidence and conclusions about evolution in the two bird species.

Mutation in the hemoglobin gene can cause sickle-cell anemia. The defective protein found in sickle-cell anemia causes red blood cells to “sickle”—become a misshapen C shape. These misshapen cells abnormally stick to each other and can become trapped by leukocytes (white blood cells) that are rolling or paused on the endothelial cells lining the vessel. This causes blockages of small blood vessels, causing severe pain and strokes called vaso-occlusive crisis. A new drug that binds and blocks selectin proteins is in phase III clinical trials to test for improvement in patients' symptoms. Why might this be an effective treatment for vaso-occlusive crisis?

Answers

This might be an effective treatment for vaso-occlusive crisis as depending on which proteins it blocks from binding, can help prevent blockages of small blood vessels . It might be bad if it also binds select proteins as useless those proteins are regulated. Otherwise they could cause blockages too

What are vascular plants?

Vascular plants are a group of plants that have specialized tissues for conducting water, minerals, and nutrients throughout the plant. These specialized tissues, called vascular tissue, consist of xylem and phloem.

Xylem is a type of vascular tissue that is responsible for transporting water and minerals from the roots to the rest of the plant. It consists of tubes made of dead cells with thick cell walls that form a continuous network throughout the plant.

Phloem is another type of vascular tissue that is responsible for transporting sugars and other nutrients throughout the plant. It consists of tubes made of living cells that are arranged in a circular pattern around the xylem.

Vascular plants are important because they are able to grow to larger sizes than non-vascular plants due to their ability to transport water and nutrients throughout the plant. Examples of vascular plants include trees, grasses, and flowers.

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.

Answers

The answer is C hope this helps

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.

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

Answers

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.
