B) No, many microorganisms, like those in your gut, are beneficial
As is turns out there are only about 100 different bacteria which are pathogenic. All other bacteria are completely harmless and, as this question states, some are crucial for proper human health as we exist in a symbiotic relationship with them. Bacteria in the large colon provide nutrients to us, and play an important role in the development of the immune system.

Hemophilia is a rare recessive genetic disorder in which the recessive version of the gene does not produce blood-clotting factors. A woman whose father had hemophilia marries a normal man. They have two children: a boy and a girl. What are the chances of the boy being a hemophiliac? _________ What are the chances of the girl being a hemophiliac? _________ Show your work with a Punnett Square.
Answer:25 , 0
Explanation:
XX©(mother being the carrier as her father was hemophilia- females can only be carrier of hemophilia ) when crossed with normal father produces offspring XX©, XY, XY©, XY. Therefore chances of boy being hemophilia=(1/4)*100=25.
Chances of girl being hemophilia= 0.

In the year 100, Ptolemy introduced the geocentric model of the solar system. By the year 1542,
Copernicus introduced a new model of the solar system called the heliocentric model. With this
example in mind, which of the statements below best summarizes what we learned from these models?
Answer: Ptolemaic system, also called geocentric system or geocentric model, mathematical model of the universe formulated by the Alexandrian astronomer and mathematician Ptolemy about 150 CE and recorded by him in his Almagest and Planetary Hypotheses. The Ptolemaic system is a geocentric cosmology; that is, it starts by assuming that Earth is stationary and at the centre of the universe. The “natural” expectation for ancient societies was that the heavenly bodies (Sun, Moon, planets, and stars) must travel in uniform motion along the most “perfect” path possible, a circle. However, the paths of the Sun, Moon, and planets as observed from Earth are not circular. Ptolemy’s model explained this “imperfection” by postulating that the apparently irregular movements were a combination of several regular circular motions seen in perspective from a stationary Earth.

What is Nervous system?Signals are sent from the brain to the rest of the body, including the internal organs, via the nervous system. Thus, the nervous system's activity regulates a variety of functions, including the capacity to move, breathe, see, and think.
The nerve cell, or neuron, is the building block of the neurological system. There are around 100 billion neurons in the human brain. A neuron has a cell body, which contains the cell nucleus, as well as distinct extensions known as axons and dendrites.
Different neuronal types control or carry out various functions. For instance, motor neurons help the brain send signals to the muscles that cause movement.
Therefore, A newly developed drug causes users to lose some muscle control and slur their words, The drug also results in a slowing of central nervous system activity. Depressants slow the central nervous system.

in VDJ recombination occurs in the Group of answer choices variable region of the heavy chain. constant region of the light chain. variable region of the light chain. Both the light and heavy chain.
Answer:
constant region of the light chain.
Explanation:
The VDJ recombination is defined as the process where the T cells as well as the B cells are randomly assembled from the different gene segments. These are mainly known as the variables (V), the diversity (D) and the gene (G). This is done in order to generate the unique receptors which is also called as the antigen receptors so that they can collectively recognize the different types of the molecules. It mainly occurs in the constant region of the light chain.

What causes 37% of all pollution?
Answer:
There are a variety of examples that cause the problematic issue of pollution- Usually air pollution can be caused by the alteration of gases, solid and liquid particles suspended into the air. If we were to contemplate on how human causes lead to pollution, vehicles exhaust fumes are possibly one of the most affecting in air pollution, as well as the exhaust from industrial factories and plants. Human reasons have majorly led to pollution.

A ________ is a unicellular or multicellular organism that is heterotropic; feeding off dead organic matter or a parasite, feeding off living organisms; reproduces through spores.
Answer:
A fungi is a unicellular or multicellular organism that is heterotropic; feeding off dead organic matter or a parasite, feeding off living organisms; reproduces through spores.
Explanation:
FUNGI -: Fungi can be single-celled organisms or multicellular organisms with a great deal of complexity. They can be found in almost any habitat, but the majority of them reside on land, primarily in soil or plant material, rather than in the sea or fresh water. Decomposers are organisms that live in the soil or on dead plant materials and play a vital part in carbon and other element cycling. Some are plant parasites that cause illnesses such mildews, rusts, scabs, and canker. Fungal diseases in crops can cause a farmer to lose a lot of money. Animals are afflicted by a small number of fungus. Athletes' foot, ringworm, and thrush are examples of human skin diseases.
Fungi play an important part in the breakdown of organic materials and in the cycling and exchange of nutrients in the environment. They've long been utilized as a direct source of human food in the form of mushrooms and truffles, as a bread leavening agent, and in the fermentation of a variety of foods like wine, beer, and soy sauce.
Hence , the answer is fungi.

How would you describe the process of genetic information being passed from parent to offspring in organisms like bacteria?
A. The organism undergoes mitosis and creates genetically diverse offspring
B. The organism undergoes meiosis and creates genetically diverse offspring
C. The organism undergoes binary fission and creates genetically identical offspring
D. The organism undergoes sexual reproduction and creates genetically identical offspring
Answer:
C. The organism undergoes binary fission and creates genetically identical offspring
Explanation:
This because binary fission is the means of reproduction in prokaryotic organisms like bacteria. This refer to the process where a single cell divided into two or more and each looking more exactly like the parent cell..
the process of binary fission, a particular parent cell replicate its genetic material or DNA and then divides into two parts by a process called cytokinesis and each new organism produced then receive one copy of DNA. This occur in bacteria
7. The _____________ is a collection of buried, long-dead organisms and can tell us information about prior ancestors - the _____________ a fossil is, the ______________ it is in age and the ___________ related it is to modern organisms.
Answer:
Fossil.
Explanation:
Fossil is a collection of buried, long-dead organisms that can tell us information about ancestors of an organism. The physical features of fossil provides information about its relationship with modern organisms. The fossil which is present in very deep in the soil are more older than the fossil that is present in less depth. We can find age of the fossil by using radiometric dating methods which tells us about the existence of fossil on the earth.
