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.

A scientist studies the DNA in corresponding genes of a platypus, a
beaver, and a duck. The DNA from which two species are most likely to be most
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.

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.

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.

Which of the following means a hormone that aids in growth of gonads?
Glycogenesis
Thyrotoxic
Pancreatitis
Gonadotropin
Answer:
thyrootoxic
Explanation:
The hormone which aids in the growth of gonads is Gonadotropin. The correct option is gonadotropin.
Gonadotropins are defined as the hormones which play an important role in the growth and development of gonads. The gonads refer to the male and female reproductive organs, such as the testes and ovaries. Gonadotropins stimulate the production of sex hormones and even regulate the reproductive processes. These homones are essential for the normal functioning of the reproductive system.
Gonadotropins are classified as glycoprotein hormones which are secreted by gonadotropic cells of the anterior pituitary which is present in vertebrates.This family includes the mammalian hormones follicle-stimulating hormone (FSH) and luteinizing hormone (LH), the chorionic gonadotropins, human chorionic gonadotropin (hCG) and equine chorionic gonadotropin (eCG),as well as at least two forms of fish gonadotropins.
Thus, the correct option is gonadotropin.

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.
