B. One parent organism and no egg or sperm.
Explanation:
In asexual reproduction, an organism can produce offspring with no gametes involved (eggs or sperm), and does not need to undergo meiosis.
If an organism produces offspring through asexual reproduction, all of the DNA from the parent will go to the offspring. Since there is only one parent, meiosis will not occur since there is no need for genetic differentiation.
All of the organisms produced by the parent during asexual reproduction will be identical to the parent. They will have the same DNA and genetic make up.

If you had the following food chain: Sun→grass→mouse→snake→bird of prey Which of the following would NOT happen if the snake trophic level was removed? A. The mouse population would decrease B. The bird of prey population would decrease C. The sun would stay the same D. The grass population would decrease
Answer:
Option A
Explanation:
If the snake trophic level is removed, the following things will happen
=> The mouse population will increase because they would no more be a prey
=> The bird of prey population will decrease because their predator is no more present
=> The sun would stay the same
=> The grass population would decrease as their predator population has increased.
The mouse population decreasing won't happen when the snake trophic
level is removed.
In the trophic level below, the snake feeds on the mouse, the bird of prey
then feeds on the snakes.
Sun→grass→mouse→snake→bird of prey
However, when the snake trophic level is removed , the mouse have fewer
predators which feeds on it. This enables the population of mouse to
increase in the ecosystem as those on top of the trophic level usually have a
smaller population to the others.

A. producing proteins
B. processing proteins
C. storing proteins
D. sorting proteins
Answer:
A. producing proteins
Explanation:
Protein synthesis takes place in ribosomes bounded to the rough endoplasmic reticulum. The Golgi apparatus performs all the other functions.
Hope this helps.
Producing proteins is not a function of the Golgi apparatus. So the correct option is A.
What is the Golgi apparatus?
A Golgi apparatus, also known as a Golgi body is an organelle in a cell. It helps in the processing and packaging of proteins and lipid molecules. It specially processes the proteins that are destined for export from the cell. It is named after Camillo Golgi, the scientist who discovered it. Its appearance resembles a series of stacked membranes.
The Golgi body is a cell organelle made up of membranes. These membranes are of different types. Some are tubules, and some are vesicles. This organelle is located near the nucleus. That is why it's called a perinuclear body. It lies right after the endoplasmic reticulum as well.
When the synthesized proteins are released from the endoplasmic reticulum, they enter the Golgi body for further processing. Processing may include the addition of carbohydrates and the formation of glycoproteins. These glycoproteins are released from the Golgi body to the rest of the cell.
These processed proteins are released and packed in vesicles. The vesicles are made out of the membranes in the Golgi network. These vesicles are filled with the products of the Golgi body and they move to the rest of the cell. This is usually through the cell to the plasma membrane, which is the destination.
Therefore, the correct option is A.

Answer:
Organisms better adapted to the environment
Explanation:
According to the evolutionary theory proposed by Charles Darwin in "The Origin of Species" (1859), the fittest organisms are those that are better suited to the environment (i.e., have a higher fitness). These organisms have more chances to survive and reproduce, and thereby they have also more chances to leave their genes in the next generation. This process is the central concept of evolution, and it is called natural selection. In consequence, evolution produces phenotypic changes or 'adaptations' that are inherited by organisms over generations, and certain traits are lost during this process.

What kind of joint allows the arm to bend?
Cartilaginous
Suture
Fibrous
Synovial
Answer:
Hey there!
The correct answer would be Synovial. A synovial joint allows the arm to bend.
The synovial (or joint) cavity is this area, and synovial fluid is what fills it. By lubricating the joint and minimizing friction between the bones, synovial fluid enables better joint movement. Thus option D is correct.
What main role of Synovial joint in bend?Keeping the articulating bones of the joint cavity from rubbing against one another is the synovial joint's main function. All synovial joints are diarthroses, but the range of motion differs between different subtypes and is frequently constrained by the ligaments that hold the bones together.
Bones may move freely thanks to movable joints. Synovial joints are all joints that may move. They also encompass the elbow, hip, and shoulder in addition to the knee. The most prevalent type of joints in the body are those that can move.
Therefore, Synovial kind of joint allows the arm to bend.

what will happen by the process of diffusion?
O A. Fructose molecules will diffuse into the cell.
B. Fructose molecules will disappear by diffusion.
C. Fructose molecules will stay where they are.
O D. Fructose molecules will diffuse out of the cell.
If the amount of fructose is more outside the cell than inside the cell, then fructose molecules will move into the cell through diffusion. The correct option is A.
What is osmosis?Diffusion is the movement of substances from a region of higher concentration to a lower concentration region. A gradient in Gibbs free energy or chemical potential aids in diffusion.
In the given scenario, as fructose molecule is in excess outside the cell and is less inside, then the fructose molecule will cross the membrane from outside the cell to inside due to this concentration gradient.
Thus, the correct option is A.

HELP!! Orchids are flowering plants that depend on bees for pollination. A population of orchids in a rainforest has reached its carrying capacity. The size of the rainforest's bee population is a limiting factor of the orchid population. What will happen to the orchids' carrying capacity if the rainforest's bee population decreases?
Answer:
The carrying capacity will decrease because the level of the limiting factor decreases.
Explanation:
Decrease in available resources lead to decrease in carrying capacity of an environment for a population. The rainforest's bee population is a limiting factor for orchid population, decrease in bee population will lead to decrease in orchid population.
Hence, the carrying capacity will decrease due to decrease in limiting factor as the number of orchids that can be sustained by the environment would decreases.

When people have their gallbladders removed, their bodies no longer have a place to store bile, and the bile flows from the liver continuously. What effect might this have on their ability to digest fats?
A. There will be very little change since bile will still be present to emulsify fats.
B. Fats will be emulsified more efficiently with the constant flow of digestive enzymes.
C. It will be unlikely that they will be able to emulsify and digest fats.
D. Only small amounts of fats will get digested since high concentrations of bile enzymes are needed for efficient digestion.
Answer:
A. There will be very little change since bile will still be present to emulsify fats.
Explanation:
The gallbladder is a pear-shaped storage sac present in the alimentary canal of humans and functions to store excess bile in between meals. The bile is a greenish-yellow substance composed of different substances like salts, bile pigments, cholesterol etc. The bile is produced in the liver and aids in the digestion of fats.
The gallbladder serves as an intermediary between the organ of bile production (liver) and its destination (intestine). According to the question, once the gallbladder is removed, there is no longer a place to store bile. However, bile will still be produced by the liver and released directly into the intestine instead.
Hence, the bile will still be present to perform its function of emulsifying fats with little changes in the way it is released into the intestine. Note that, the gallbladder only regulates the speed at which the bile is released into the intestine.
