Answer:
Amphibians are known to have very thin, moist skin and lay eggs without shells. Because of this, they are extremely sensitive to biological changes, such as chemicals in the air or water, and climate change. This makes amphibians ecological indicators; this means that amphibians are the first signs of an unhealthy ecosystem. When large amounts of amphibians grow or die, this means there is a problem with the ecosystem.

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.

Cell Membrance- The functions of cell membrane are:
They keep toxic substances out of the cell.It only allows sensitive material to enter and exist in cell.12. Which has NOT been linked to acid precipitation?
a. Toxic metal poisoning
b. Lower blood pH
c. Respiratory problems
d. Damaged monuments
Answer:
D
Explanation:
Lower blood pH has not been linked to acid precipitation. So, the correct option is (B).
What is Acid Precipitation?Acid rain is defined as rain or any other form of precipitation that is abnormally acidic, meaning that it contains high levels of hydrogen ions. Most water which include drinking water, has a neutral pH that exists between 6.5 and 8.5, but acid rain has a pH level lower than this and averages between 4–5.
Acid rain can be caused by natural causes, such as volcanic eruptions, while acid rain can also caused by human activities such as the burning of fossil fuels, manufacturing, oil refineries, electricity generation, and vehicles, all of which release sulfur and nitrogen oxides into the atmosphere.
Thus, lower blood pH has not been linked to acid precipitation. So, the correct option is (B).

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.
Explain Newton’s First Law and give an example of it
Answer:
When a person jumps out of a moving vehicle, he falls forward due to inertia of motion. One example of Newton's first law in real life is, when you are walking with a glass filled with water, you will notice that the water spills at certain locations when you walk at faster pace. The water inside the glass will remain at rest until you move.
Explanation:
Answer:Newton's first law states that, if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.
An object at rest stays at rest.

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

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.

In the presence of arsenate poisoning glycolysis is interrupted. ATP production proceeds via a reaction that involves 1,3-bisphosphoglycerate. a net production of 2 molecules of ATP occurs. All of the above None of the above
Answer:
glycolysis is interrupted.
Explanation:
The presence of arsenate can poison the process that inhibits ATP production which occurs during the process of glycolysis. Arsenate inhibits ATP formation during the process of glycolysis by substituting arsenate for the phosphate anion in a process known as arsenolysis. Arsenic has to inhibits cellular respiration by inducing mitochondrial enzymes and uncoupling oxidative phosphorylation.
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.
