The red sizing bead in this image is 10um in diameter. What is the length of a chloroplast? a20um b100um c2um d1um e10um
Answers
The length of the chloroplast in the image is 100um.
In the attached image we can observe a red circle known as a red sizing bead over the chloroplast. Given that the size of the bead is 10um in diameter, we can conclude that the width of the chloroplast falls in the range of about 30um. By observing that the length is much greater than the width, we know it must be at least higher than 30, and it would seem to be approximately three times as much. With this information, we can conclude that of the options given, the chloroplast would be 100um in length.

Pepsin, a common enzyme found in the stomach, is most active at pH values between 0.5 and 2.5. It works slowly between pH values of 2.6 and 3.4. Beyond a pH of about 3.5, it becomes completely inactive. Why does this happen? A) The enzyme inactivates because it melts into a liquid when it is not at the right pH. B) The protein chain in the enzyme is denatured, permanently inactivating it as the pH approaches 7. C) The enzymes slow down, because changing the pH changes the temperature as well, and affects the reaction.

b . aggressiveness

witch of the following is the answer
Answers
Undesirable traits people should avoid when driving are aggressiveness, exhibition and egotism. These traits and characters are simply interrelated and interdependent with one another, without egotism or self-centeredness, you wouldn’t consider being hostile and belligerent towards others in the road, you’d paved way and averts exhibition which can cause accidents and unexpected disaster while handling the vehicle. Being considerate beats all three of these traits, they only not jeopardize the driver’s life or the vehicle but mostly especially can cause severe clinical conditions on the victim. Driving is not a game nor for “show off”. It also needs respect and when respect is to be earned you’ve earned it by being on the road like everyone else has.

Organisms within an ecosystem are biotic factors in that ecosystem. Thus, option B is correct.
What are biotic factors?
The term biotic factors has been defined as living factors present in the ecosystem. Biome is a separate biogeographical region that contains its own living and non-living factors along with a characteristic climate. The examples of biomes are: Tundra, Temperate, Desert, etc.
Changing a biotic or abiotic factor can affect each other or even the entire biome because these factor live in a state of dynamic equilibrium by being interdependent on each other. Therefore, if this equilibrium is disturbed then the survival of some living organism may be disturbed that can eventually lead to ecological succession.
The nitrogen cycle is a biogeochemical succession process of nitrogen that involves: fixation, ammonification, nitrification, and denitrification. Like any other biogeochemical cycles. This process undergoes and affects the biological, geometrical and chemical aspects in the ecosystem and the abiotic and biotic community.
Therefore, Organisms within an ecosystem are biotic factors in that ecosystem. Thus, option B is correct.

Roots have all of the following functions EXCEPT to - d. make food
The root is the part of a vascular plant that is normally underground. Its primary functions are
- Anchorage of the plant,
- absorption of water and dissolved minerals
- conduction of these to the stem, and storage of reserve foods.
- Conduction of absorbed water and minerals occurs from roots to the other parts of the plants.
- Storage of food minerals, in some plants, for future needs, and for vegetative propagation.

Explanation:
microalgae elodea maple leaf and root hair are eukaryoti organisms and they have nucleus, cell wall and membrane in common and these structures perform different functions.
Nucleus is a membrane bound organelles that contain the DNA or genetic material . It is majorly found in eukaryotic organisms.
Vacuole is a membrane bound organelles that function in digestion, ingestion, excretion of waste and storage.
Cell wall is a structure that give shape, support and protection to cells.
Membrane is a structure that separate the internal of the cell from it outside environment and it give protection to the cell..
