In which squares should the phrase “Yellow pods” appear?
Answers
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.

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
Answers
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.

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.
Answers
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.

Describe what would happen to the abiotic factors within the ecosystem if the bacteria were eradicated from the ecosystem.
Answers
Answer: If a abiotic factor was to be removed from the ecosystem it can affect the entire ecosystem and all of the organisms that live there
Explanation:
Abiotic means which does not have life for example air, water, soil. Absence of bacteria can influence the abiotic factors in adverse ways.
What are abiotic factors?Abiotic components plays a major role in ecosystem, while biotic components are dependent on abiotic factors for their survival.
Both abiotic and biotic factors are related to each other, if any of these factors changes, it will adversely affect the ecosystem.
For instance, if bacteria were eradicated from ecosystem, it will affect the functioning of abiotic components which can result in increased pH, decreased decomposition etc.
Thus, the abiotic factors will get affected adversely if bacteria were eradicated from the ecosystem.

Name 4 ways that different types of disease can interact to make a person ill.
Answers
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.
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.
Answers
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.

b.) CO2 + sugar + H2O --> O2 + light
c.) O2 + light + H2O --> CO2 + Sugar
d.) CO2 + O2 + H2O --> Light+ Sugar
Answers
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.

Explain how the shape of a river's stream bed can affect the river's speed and its power to cause erosion.
Answers
Explanation: The shape of a river's stream bed affects the speed and eroding power of a river by influencing the amount of friction between the water flowing through the river and the stream bed below. Friction is the force that opposes the motion of one surface as it moves across another surface. In a river, there is friction between the flowing water and the stream bed beneath it. Where a river is deep, less water comes into contact with the stream bed, so there is less friction. The reduced friction means there is less opposition to the water's motion, so the river flows at a greater speed and has more kinetic energy for erosion. On the other hand, where a river is shallow, more water comes into contact with the stream bed, so there is more friction. The increased friction means there is more opposition to the water's motion, so the river flows at a lesser speed and has less kinetic energy for erosion. Also, the roughness of a stream bed covered with boulders and other obstacles causes the water to flow through the river in a turbulent fashion. This could cause the river to move slower in some cases or erode more in other cases.
*mark as Brainliest ty*
Answer:
It changes the amount of friction there is. There is more friction where water is shallow, and less friction where water is not as shallow. The friction has the power to cause erosion as it causes movement of water.
