What do you mean by biome?A biome is a biogeographical unit consisting of a biological community that has formed in response to the physical environment in which they are found and a shared regional climate.
A biome is an area classified according to the species that live in that location. Temperature range, soil type, and the amount of light and water are unique to a particular place and form the niches for specific species allowing scientists to define the biome.
There are five major types of biomes: aquatic, grassland, forest, desert, and tundra, though some of these biomes can be further divided into more specific categories, such as freshwater, marine, savanna, tropical rainforest, temperate rainforest, and taiga.

1. How does the equations help explain the role of
producers in the ecosystem?
1. Producers create energy for other organisms to consume.
2. Producers convert sunlight into usable energy and Nitrogen.
3. Producers convert carbon dioxide and water into sugar.
4. Producers create Carbon dioxide for other organisms.
2. Aerobic Cellular Respiration is important to organisms because
1. It allows plants to produce sugar for food.
2. It releases the oxygen needed by plants for photosynthesis.
3. It converts sugars to usable energy that all organisms need.
4. It helps animals digest the sugars when they eat plants.
Answer:
1. Producers create energy for other organisms to consume.
2. It converts sugars to usable energy that all organisms need
Explanation:
All living organisms require energy, which they obtain by feeding on one another in an ecosystem. The series of feeding steps involved is called FOOD CHAIN. Food chain always starts with an organism called PRODUCER, which is an autotroph i.e. capable of producing its own food by using light energy from sunlight e.g plants. All other organisms in the food chain are directly or indirectly dependent on plants to get energy. This is because plants and other autotrophs create the energy that is being transferred as the food chain progresses.
2. Cellular respiration is an important phenomenon for all living organism because it is the metabolic process by which they obtain the usable energy by their cells i.e. ATP. Food molecules in form of sugar (glucose) eaten by organisms are broken down in the presence of oxygen (aerobic) to yield ATP molecules, which is the energy currency of every living cell. This energy is used to perform the organism's life activities.

Sugar, orange juice, and ice are all examples of matter. The truth about all three is they are made of particles too small to be seen. The correct option is B.
Anything that fills space and has mass is referred to as matter; in other words, the matter is the "stuff" that the cosmos is made of. Elements are the fundamental building blocks of all matter.
They possess unique chemical and physical characteristics and cannot be converted into other elements through regular chemical processes. Anything that can be weighed and takes up space is considered the matter.
Therefore, the matter has both mass and volume. The universe is made up of a wide variety of substances and forms of matter.
Therefore, the correct option is B. They are made of particles too small to be seen.

Which of the following is the correct equation for photosynthesis?
a.) CO2 + light + H2O --> O2 + Sugar
b.) CO2 + sugar + H2O --> O2 + light
c.) O2 + light + H2O --> CO2 + Sugar
d.) CO2 + O2 + H2O --> Light+ Sugar
Answer: a
Explanation: light is a energy sourse for the photosintesis and sugar is glucose wich is the food formd at the end of phothosintesis like oxigen..(etc..)....
The answer option with the correct equation for photosynthesis is: A. [tex]CO_2 + light + H_2O --> O_2 + Sugar[/tex]
Photosynthesis can be defined as a biological and chemical process through which living organisms such as green plants (autotrophs), transform light energy (sunlight) into chemical energy.
The correct equation for photosynthesis is given by this chemical equation:
[tex]CO_2 + light + H_2O --> O_2 + Sugar[/tex]
Hence, the necessary input for the process of photosynthesis to take place include the following:
Water ([tex]H_2O[/tex]).Sunlight (light energy).Carbon dioxide ([tex]CO_2[/tex]).
In conclusion, oxygen and sugar are end products (output) of photosynthesis rather being an input.

Name 4 ways that different types of disease can interact to make a person ill.
Answer:
Modes of transmission or means of transmission is defined as the movement or transmission of pathogen from infected person or any reservoir to other person.
4 ways or modes of transmission of diseases include:
Contact (direct and/or indirect) - Direct contact include physical relation between infected person or susceptible person such as kissing, sexual contact or transfer of oral secretion. Diseases caused by direct contact include small pox, pink eye and hepatitis a and B. Indirect contact include transmission of diseases form infected person to susceptible person through a infected surface such as infected needle.Droplet: water droplet coming out of the mouth, perspiration or other open parts of the body carries pathogens to susceptible person. sneezing and coughing are most common of droplet ways through which diseases spread.Airborne: Some of the diseases are spread through means of air such as chickenpox virus, norovirus, measles morbillivirus, Mycobacterium tuberculosis and influenza virus et-cetra.Vector: Vectors are defined as an organism that carries disease causing pathogens from infected person to other host body. Fleas or other insects are example of vectors.Hence, 4 ways that different types of disease transmission that can make a person ill are droplet, Contact (direct and/or indirect), vectors and airborne.

When Engelmann exposed photosynthetic algae to light in the presence of aerobic bacteria, he found that some wavelengths of light produced a higher rate of photosynthesis, as evidenced by the number of bacteria gathered near the algae. Based on his results, what color of light did Engelmann find associated with the highest rate of photosynthesis?
A. Red and blue
B. Yellow and green
C. Yellow
D. Red
Answer:
A. Red and blue
Explanation:
Theodor Wilhelm Engelmann, born in 1843 and died in 1909, was a German scientist. He was the scientist who detected which wavelengths of light produced the best photosynthetic activity in green alga. In his experiment, Engelmann exposed the photosynthetic algae to different wavelengths in the light spectrum. He then added aerobic (oxygen-dependent) algae to see where they will accumulate the most in order to detect the best wavelength for algae photosynthesis.
He discovered that the aerobic bacteria accumulated in the parts of the algae exposed to red and blue wavelength of light. This is because the algae exposed to the red and blue light produced more oxygen due to increased photosynthetic rate. This attracted the aerobic bacteria, which needs oxygen, to that particular area with that wavelength.
Why do elderly persons often develop bowed back and appear to lose height?
Answer:
When we get older, we experience a loss of bone density and our bones begin to thin and become weaker, which results in osteoporosis, causing us to develop bowed backs and appear to lose height.
We lose bone density as we age, and our bones start to thin and weaken. This leads to osteoporosis, which makes us appear smaller and causes us to acquire bowed backs.
What is osteoporosis ?Osteoarthritis is an osseous disease that arises when the body makes either too little bone or loses too much bone. Like a result, bones deteriorate and are more prone to breaking from a trip or, in extreme circumstances, from tiny bumps or sneezes. Under a magnification, healthy bone resembles a honeycomb; the term "osteoporosis" refers to porous bone.
What is treatment of osteoporosis?Typically, bisphosphonates are used initially for treating osteoporosis. Among these is the when first tablet Alendronate (Fosamax). Weekly or monthly pills of was also (Actonel). Ibandronate (Boniva), a tablet taken every month or an IV infusion given every 3 years. The most accurate test for identifying osteoporosis and determining the risk of fracture is commonly believed to be bone density testing by DXA now at hip and spine. Some persons get peripheral DXAs, which assess the thumb and heel bone densities.

similar? Explain your answer.
Answer:
platypus and a duck has similar DNA.
Explanation:
There are certain similarities which are present between duck and platypus such as structure of beak or mouth, webbed feet and laying eggs in order to continue its generation. These three characteristic make the platypus and duck similar to each other. There is also one major difference is present which is that the platypus is the only mammal which lay eggs and feed baby with their own milk. Its tail structure is also different from duck.
The DNA from platypus and beaver are most likely to be most similar because these species share a more recent ancestor.
Sequence homo-logy refers to the level of similarity between nucleotide (DNA) sequences due to shared ancestry in the evolutionary history of life.The species that share a more recent ancestor exhibit a higher level of sequence homo-logy than unrelated species.In this case, the linear order of nucleotides in DNA from platypus and beaver are most likely to be most similar because they are mammals, while ducks are birds.In conclusion, the DNA from platypus and beaver are most likely to be most similar because these species share a more recent ancestor.

The given question is incomplete however the correct question and the flow chart is related to the question as follows:
The flowchart below shows the three generations of a cross between a pea plant that has yellow pods and a pea plant that has green pods. yellow pods are the dominant trait. The flowchart is missing the labels that describe the traits.
In which squares should the phrase “yellow pods” appear?
1. A and D
2.B and E
3. A, C, and D
4. A, B, C, D, and E
Answer:
The correct answer is: 3. A, C, and D
Explanation:
According to Mendel’s laws of inheritance, when a plant with the dominant trait is crossed with a plant with a recessive trait, as a result, the dominant phenotype appears in all the F1 offspring. On Self cross F1 offspring, produces F2 offspring with dominant and recessive traits.
In the given scenario, pea plant with ‘yellow pods’ are dominant and pea plant with ‘green pods’ is recessive.
Therefore, when pea plant with yellow pods is crossed with the pea plant with the green pod, the F1 offspring (C) produced are with yellow pods.
Thus, parent (A) is with yellow pods and F2 offspring (D) is with yellow pods.
