Answer:
kill cells and tissues outright
Explanation:
Sometimes bacteria multiply so rapidly they crowd out host tissues and disrupt normal function. Sometimes they kill cells and tissues outright. Sometimes they make toxins that can paralyze, destroy cells' metabolic machinery, or precipitate a massive immune reaction that is itself toxic

The work of such researchers as Broca, Fritsch, Hitzig, and Ferrier demonstrated localized brain function, which was somewhat similar to the predictions made by ________.
The work of Broca, Fritsch, Hitzig, and Ferrier demonstrated localized brain function, which was similar to predictions made by phrenologists. Phrenology is a pseudoscience.
Phrenology is a pseudoscience aimed at measuring bumps on the skull to predict personality traits.
Eduard Hitzig and Gustav Fritsch demonstrated that electrical stimulation of specific areas of the cerebral cortex could trigger movement.
Broca's area is an area located in the frontal part of the left brain hemisphere discovered by Paul Broca, who observed how this area has a fundamental function for the generation of speech in humans.
Finally, David Ferrier was a neurologist who discovered a series of motor fields within the cerebral cortex of monkeys.

Which statement explains why ammonites are a good example of an index fossil?
Answer:
Ammonites existed only in the oceans.
Explanation:
Index fossils serve as a relative dating marker for geologic time periods and the rocks formed at those times. The fossils are of species that lived for only a short while, though that could be millions of years, and were widespread on the Earth. Ammonites are good index fossils for several reasons. First, they are easily identified by their spiral shells.

Answer:
Sunlight
Explanation:
Plants rely on the energy in sunlight to produce the nutrients they need. But sometimes they absorb more energy than they can use, and that excess can damage critical proteins. To protect themselves, they convert the excess energy into heat and send it back out.
how can the h. pylori bacteria survive in the human stomach?

a bacterium is infected with an experimentally constructed bacteriophage
The complete question is:
a bacterium is infected with an experimentally constructed bacteriophage composed of the T2 phage protein coat and T4 phage DNA. The new phages produced would have
A) T2 protein and T4 DNA
B) T2 protein and T2 DNA
C) a mixture of DNA and proteins of both phages.
D) T4 protein and T4 DNA
E) T4 protein and T2 DNA
A bacterium infected with an experimentally constructed bacteriophage will give new phages with the virus' DNA and the type of proteins that this DNA encodes.
A bacteriophage is a virus that attaches itself to a bacteria and uses it to replicate itself. Viruses have two main parts, a protein coat and their DNA inside it.
The experimentally constructed bacteriophage has one type of protein that makes the coat, the T2. This type of protein will allow the virus to attach and infect the bacteria. Once the virus attaches itself to the bacteria, it will introduce its DNA, T4 type, and use the bacteria elements to replicate it and create new phages.As a result, the new phages will have T4 DNA, and the proteins that the virus synthesizes will be the same type as the DNA.
In conclusion, The new phages produced would have D) T4 protein and T4 DNA.

Where in the cell would you expect to find the greatest activity of the pyruvate dehydrogenase complex?
Answer:
Mithochondria
Explanation:
In eukaryotes, the pyruvate dehydrogenase complex, like the enzymes for citric acid cycle and oxidation of fatty acids, is located in the mitochondrion, where is associated with the surface of the inner membrane facing the matrix.
In the cell, mitochondria are the place where it expects to find the greatest activity of the pyruvate dehydrogenase complex.
What is the pyruvate dehydrogenase complex?The three-enzyme complex known as the pyruvate dehydrogenase complex (PDC) is responsible for pyruvate carbonylation, which converts pyruvate to acetyl-CoA.
This complex connects the glycolysis metabolic pathway to the citric acid cycle by allowing acetyl-CoA to be used to perform cellular respiration.
The enzyme pyruvate dehydrogenase catalyzes the reaction between pyruvate and a lipoamide, which yields acetylated dihydrolipoamide and carbon dioxide. The process requires the coenzyme thiamine pyrophosphate.
Therefore, the site where you find the greatest activity of the pyruvate dehydrogenase complex is mitochondria.

Scientists can study the human genome using DNA fingerprinting.
DNA fingerprinting allows scientists to
B. break the hydrogen bonds in a gene to allow DNA to replicate itself.
c. determine the location of an abnormal gene on an individual's
chromosome.
A. prevent a gene from matching complementary bases onto a strand of
RNA.
Answer:
your answer is C.
Explanation:
DNA fingerprinting allows researchers to determine the location of an abnormal gene in a person's chromosomes.
What are the steps in DNA fingerprinting?DNA fingerprinting is a laboratory technique used to determine the likely identity of a person based on the nucleotide sequences of certain regions of a person's DNA that are unique to individuals.
DNA fingerprinting was used early in legal disputes, particularly in solving crimes and establishing paternity. It is also used to detect inherited genetic diseases and can be used to identify genetic matches between tissue donors and recipients.
In DNA fingerprinting, researchers collect DNA samples from various sources, such as hair from crime scenes and blood from victims and suspects. They then narrow down scattered sections of repetitive DNA in these samples.

Bioremediation is that process which use the biological organisms to protect and repair the environment.
Bioremediation refers to the use of biological agents or processes in order to protect and repair the environment from negative human impacts. This phenomenon depends on stimulating the growth of specific type of microbes that utilize contaminants such as oil, solvents and pesticides as a sources of food and energy.
These microbes has the ability to use these harmful substances as a food and convert these contaminants into water as well as harmless gases like carbon dioxide so we can conclude that bioremediation is that process which use the biological organisms to protect and repair the environment.
