Answer:
microbes can sense and respond to exogenous molecules associated with danger. Danger signals can be damage-associated molecules derived from kin cells. Various pathways transduce danger signals to launch protective cellular responses.
How would a tubal ligation or vasectomy influence meiosis in individuals who elected to have one of these operations
Vasectomy and Tubal ligation are operations that have an effect on meiosis in individuals who have elected to have these operations in that it causes meiosis to stop.
A vasectomy or Tubal ligation are operations that are often performed as a method of birth control. A vasectomy is the male version of the operation and includes a procedure that negates the gametes or sex cells from reaching the sperm and being ejected from the body, thus preventing fertilization.
Tubal ligation is a similar process performed on women. The goal of this operation is the same as in the vasectomy, to stop the "egg cell" from being released and thus preventing it from being fertilized. Both procedures have been shown to cause meiotic arrest in individuals following the operation, In some cases, meiosis resumes after some time.

How are scientific theories and scientific laws different? How was the theory of evolution developed? Where can we observe evidence of organisms changing in response to their environment? How do populations of organisms change in response to their environment? What types of adaptations can be observed in nature?
Answer:
Natural selection is one of the central mechanisms of evolutionary change and is the process responsible for the evolution of adaptive features. Without a working knowledge of natural selection, it is impossible to understand how or why living things have come to exhibit their diversity and complexity. An understanding of natural selection also is becoming increasingly relevant in practical contexts, including medicine, agriculture, and resource management. Unfortunately, studies indicate that natural selection is generally very poorly understood, even among many individuals with postsecondary biological education. This paper provides an overview of the basic process of natural selection, discusses the extent and possible causes of misunderstandings of the process, and presents a review of the most common misconceptions that must be corrected before a functional understanding of natural selection and adaptive evolution can be achieved.

Living cells only within the root, fruit, and flower tissue types in this plant require mitochondria to supply the ATP that directly fuels growth and development. True or False.
Answer:
EVERY SINGLE GOD DARN STAGE. from the seed to the fruit
Explanation:
False.
Living cells in all parts of a plant are able to carry out respiration in their respective mitochondrion to supply the ATP needed for their metabolism.
As long as a cell is living, irrespective of the part of a plant it is located, such cell would be able to carry out essential life processes. Living cells in plants contain mitochondrion, an organelle that serves as the platform where energy (in the form of ATP) is generated for the various cellular metabolisms.
Thus, saying that living cells only in some specific locations in plants require mitochondrion to supply the ATP needed by cells is false.

Explain how the process of PCR can be used in the identification of a disease pathogen. Provide evidence and examples from the outbreak investigation in Unit 1.
Answer:
-in PCR they'll amplify the DNA sequence of the pathogen , then after sequencing , they'll identify the identity of this DNA and identify the pathogen by comparing its genes with the gene bank.
Explanation:
The process of PCR can be used in the identification of a disease pathogen through which the DNA sequence of a pathogen is successfully amplified and then it is matched to the sequence of that which is kept in the gene bank.
What is PCR?PCR stands for Polymerase Chain Reaction. It is a type of reaction in which the amplification of a specific DNA sequence is carried out in vitro. This technique was developed by Kat Mullis in 1985. The whole process is carried out in three stages. They are as follows:
Denaturation.Annealing.Extension.During a PCR test, a small amount of genetic material in a sample is copied multiple times. The copying process is known as amplification. If there are pathogens in the sample, amplification will make them much easier to see.
Therefore, the process of PCR can be widely used in the identification of a disease pathogen.

Viruses are alive. True or False?
• order based on the cell
• response to stimuli
.reproduction adaptation
growth and development
regulation and homeostasis
• energy processing
True or False
Answer:
False
Explanation:
Viruses are not living things. Viruses are complicated assemblies of molecules, including proteins, nucleic acids, lipids, and carbohydrates, but on their own they can do nothing until they enter a living cell. Without cells, viruses would not be able to multiply. Therefore, viruses are not living things.
( simpler way )
Viruses need something to cling onto or mooch off of in order to actually be able to fuction.

Explanation:
Tornadoes are natural events that many people find both frightening and intriguing. The word “tornado” derives from the Spanish words “tornar,” which means “to turn,” and “tronada,” which means thunderstorm. People can recognize tornadoes by their funnel shape, which consists of violently rotating winds. These winds can reach up to 200 to 300 mph in the strongest of tornadoes and cause severe damage to towns or cities.
A tropical cyclone is a rotating low-pressure weather system that has organized thunderstorms but no fronts (a boundary separating two air masses of different densities). Tropical cyclones with maximum sustained surface winds of less than 39 miles per hour (mph) are called tropical depressions. Those with maximum sustained winds of 39 mph or higher are called tropical storms.

They process oxygen and convert it into water.
They absorb large amounts of oxygen.
They produce half of the world’s oxygen.
They store oxygen in their bodies.

The ocean produces oxygen through the plants (phytoplankton, kelp, and algal plankton) that live in it. These plants produce oxygen as a byproduct of photosynthesis, a process which converts carbon dioxide and sunlight into sugars the organism can use for energy.

Answer:
Darwin's theory consisted of two main points; 1) diverse groups of animals evolve from one or a few common ancestors; 2) the mechanism by which this evolution takes place is natural selection. This SparkNote will first take a look at Origin of the Species, and then more closely examine Darwin's theories.
Answer:
Natural selection is a nature-made selection, and artificial selection is a man-made selection. Artificial selection is the process by which humans select certain naturally occurring variations to use in breeding new plants and animals. Darwin thought that a similar process in nature could explain how organisms change over time.
