Answer:
The probability of exactly 3 heads in 10 tosses is 1201024.
The probability that result will be head in the next toss is 1/2.
What is Probability?This is a mathematical term which is used to describe how likely an event is to occur or how true a proposition is. In this scenario, we have two variables which are head and tail.
The probability probability of tossing heads in your next toss is therefore
1/2 = 50% chance.

Answer:
1. dopamine and serotonin
2. brain and spinal cord
3. controls the function of different processes in the body
4. limbic system
5. Increase brain surface area
6. release hormones into the bloodstream
7. insulation
8. laughing has multiple positive functions in the body
Explanation:
Dopamine is a neurotransmitter (i.e., a chemical messenger) involved in responses to rewards, motivation and memory, while serotonin is another neurotransmitter that controls appetite, mood, wakefulness and sleep onset. The central nervous system (CNS) consists of the brain and spinal cord. The spinal cord acts as a conduit by which messages are sent from the brain to the body and from the body to the brain. Moreover, the brain acts to control all body abilities (e.g., thinking, talk, feeling, walking, breathing, etc). The autonomic nervous system is known to modulate different processes (e.g., blood pressure, digestion, breath) and internal organs (e.g., heart) by acting largely unconsciously, i.e., without a person's conscious effort. The limbic system is a part of the brain that acts to control emotions and memory by modulating autonomic/endocrine functions. Convolutions, folds, and fissures can increase brain surface area, thereby more neurons are packed into the cortex of the brain and thus it is possible to process more information. The endocrine system acts to release hormones into the bloodstream. These hormones travel in the blood to their target cells/tissues, where they regulate different functions (e.g., mood, growth, development, metabolism, reproduction, etc). The myelin is an insulating layer surrounding nerve cells that enables electrical impulses to transmit efficiently around the whole body. Laughing has multiple positive functions: release endorphin hormones that decrease stress, increases the number of immune cells and antibodies, stimulate the activity of internal organs (e.g., heart), quickly relax the muscles, contribute to increase the oxygen uptake rate in blood, etc.
interpreting graphics the biodiversity hot spots shown in figure 9 share several characteristics besides a great number of species. look at the map, and name many as many shared characteristics as you can.
When farmers clear a forest and plant crops, how will the biodiversity of the land be affected?
The biodiversity will decrease with higher populations of fewer species,
The biodiversity will increase with lower populations of more species.
The biodiversity will decrease with lower populations of more species.
The biodiversity will increase with higher populations of fewer species.
Answer:
The biodiversity will decrease with lower populations of more species.
Explanation:
This is because clearing a forest destroys habitats and therefore kills animals as they have no shelter, no food source and no water source.

What type of microbe is used in a vaccine .
Answer:
answer is below
Explanation:
Several of these structures have been used to generate bacterial vaccines. Toxoids are chemically inactivated toxins from bacteria like Clostridium tetani or Corynebacterium diphtheria. The infection with these bacteria itself does not cause the illness, but rather the exotoxins released from the bacteria.
Vaccines are made from microbes that are dead or inactive so that they are unable to cause disease. The antigen in the vaccine is the same as the antigen on the surface of the disease-causing microbe. The vaccine stimulates the body to produce antibodies against the antigen in the vaccine.
What causes there to be a H+ ion concentration gradient to build up inside the thylakoid space? Check all that apply.
a.) The electrons provide energy for the H+ pump to transport more H+ ions into the thylakoid space.
b.) A special enzyme produces more H+ ions.
c.) Photons of light create more H+ ions.
d.) The photolysis of water releases H+ ions into the thylakoid space.
Answer:
a.) The electrons provide energy for the H+ pump to transport more H+ ions into the thylakoid space.
d.) The photolysis of water releases H+ ions into the thylakoid space.
Explanation:
The thylakoid, which is found in the chloroplast, is the site of the first stage of photosynthesis (LIGHT DEPENDENT STAGE) in the cells of plants. The light stage of photosynthesis functions to produce energy (ATP) and NADPH for the second stage called Calvin cycle.
However, this ATP is generated by the power realized from the pumping of Hydrogen ions (H+) into the thylakoid lumen. The following causes the build up of H+ ions in the thylakoid space:
- Light photon hits the chlorophyll molecule, which is the photosynthetic pigment, to become charged. The electrons (e-) generated from this provide energy for the H+ pump to transport more H+ ions into the thylakoid space.
- Photolysis of water, which involves the splitting of water to produce hydrogen ions (H+) causes a build up of H+ in the thylakoid space.

Members of the Kingdom Plantae are characterized by _ while members of the Kingdom Fungi are characterized by ---
cell walls of cellulose; cell walls of chitin
heterotrophy, autotrophy
mostly unicellular organisms; having segmented bodies with jointed appendages
having segmented bodies with jointed appendages; mostly unicellular organisms
d
Answer:
Heterotrophy, Autotrophy
Reasoning: Heterotrophy organisms are organisms who can't retrieve food themselves and use energy and sunlight in order to get their food, which is exactly what plant cells do. Autotrophy is the ability to produce things such as carbon dioxide and oxygen, which plants do as well. Hence, Heterotrophy and Autotrophy are the most reasonable answers.

All cells come from parent cells that exchange DNA.
All living things are composed of single cells or multiple cells.
All cells grow and develop until they reach a certain size, at which point they die.
All cells are equipped with structures that enable motion, such as pseudopods or flagella.
All living things are composed of single cells or multiple cells. Therefore, option B is correct.
What is cell theory?Cell theory is given by Schleiden and Schwann. According to this theory, cells make up every biological entity; they are the basic building block of life, and all life originates from earlier forms of life. Today, the cell idea has become one of the guiding concepts of biology due to its widespread acceptance.
A cell is the lowest form of life. This indicates that a cell cannot be divided into smaller units and yet be considered to be alive. An entire organism, such as a person, can be divided into smaller parts, such as organ systems, organs, and tissues.
Organisms can be unicellular or multicellular. Therefore, option B is correct.

A museum curator collects fossils from two different periods. He has 400 from one period and 204 from a later period. He plans to arrange the fossils in display cases so that each case contains the same number of fossils. Also, each case must contain fossils from only one period. What is the largest number of fossils that can be placed in each case
Answer:
4
Explanation:
Number of fossils collected over period 1:
400
Number of fossils collected at a later period :
204
For each display case to have the same number of fossils ; the greatest number of fossils possible per case:
Obtain the greatest common factor of both 400 and 204
400 = 1, 2, 4, 5, 8, 10, 25, 40, 50, 80, 100, 200, 400
204 = 1, 2, 3, 4, 6, 12, 17, 34, 51, 102
Hence, the greatest common factor (400 and 204) is 4
Hence, the greatest Number of Fossil possible per case = 4

Which statement is correct?
A.
All organisms that can synthesize their food by means of photosynthesis are heterotrophic.
B.
All organisms that cannot synthesize their food by means of photosynthesis or chemosynthesis are heterotrophic.
C.
All organisms that cannot synthesize their food by means of photosynthesis are heterotrophic.
Answer:
B. All organisms that cannot synthesize their food by means of photosynthesis or chemosynthesis are heterotrophic.
Explanation:
There are three ways for a plant to obtain their food, photosynthesis, chemosynthesis, and heterotrophic. Photosynthesis is when the plant makes it's own food. If it can not get it's food from chemosynthesis or photosynthesis, it has to be an heterotrophic plant. The answer to the question is B. All organisms that cannot synthesize their food by means of photosynthesis or chemosynthesis are heterotrophic.
