The correct answer is option B, Bio genous Sediment
Reason -
The calcareous ooze is known as biogenous sediment as it has formed from the calcareous microscopic shells of the living organism. These oozes have primarily developed due to the deposition of soft muds in the ocean floor made up of calcium or diatoms or radiolarians.. These biogenous sediments are found in the form of a) mineral calcite and b) aragonite.
Calcareous ooze is an example of bio genous sediment and the correct option is option B.
Bio genous sediments are formed from the remains of marine organisms such as shells, skeletons, and other calcareous or siliceous materials.
Calcareous ooze specifically refers to sediment composed mainly of the calcium carbonate shells or tests of microscopic marine organisms like foraminifera and coccolithophores.
These organisms extract calcium carbonate from the water to build their protective structures, and when they die, their remains settle to the ocean floor, accumulating over time to form calcareous ooze. It is important to note that terrigenous sediments, which originate from land sources, can also mix with bio genous sediments in some areas, creating a combination of both types of sediment.
Thus, the ideal selection is option B.

The amnion, allantois, yolksac, and chorion are fluid-filled membranes that allow the embryo to survive inside the egg. The amnion, which is filled with amniotic fluid and provides the embryo with a stable fluid environment, surrounds and protects the embryo.
What is an amniotic egg?
A water-retaining shelled egg with four membranes that allows reptiles, birds, and egg-laying mammals to complete their life cycles.
There are membranes present, namely:
Thus, these are some membrane that is integral part of the amniotic egg.

Answer:
alveoli
Explanation:
The alveoli are small pockets present in the lungs. They are extremely important in the living organism, because the carbon dioxide that is excreted passes directly from the blood to the alveoli. These pulmonary pockets are located inside the lungs and originate through the bronchial branches, have a spongy appearance and vascularized walls.
It is in the alveoli that the gas exchange essential for living organisms occurs. The alveoli have a very thin membrane that separates air from blood, it is because of this membrane that carbon dioxide is excreted.
The prairie grass in this ecosystem is the primary producer, which stores most of the energy in this ecosystem to provide this energy to all other organisms, hence option B is correct.
In this ecosystem, there is a continuous flow of energy due to the interaction of the biotic and abiotic factors, this ecosystem includes prairie dogs, coyotes, vultures, and prairie grass.
The primary producer of this ecosystem prairie grass is an autotroph by using the process of photosynthesis, they used make their own food having more amount of energy other than any tropic level.
All the organism in the ecosystem depends on the primary producer for their energy need, so indirectly on the sun.
Therefore, prairie grass in this ecosystem provides energy to all other organisms in this ecosystem.

Answer:
200 cm/s
Explanation:
Don't listen to the other answer! I got this question marked wrong for 100cm/s, the correct answer is 200cm/s.
Answer:
Independent variable: The fertilizer given
Dependent variable: Daily plant growth
Constants: How much water they receive daily, How much sunlight the plants receive, type of plant (tomato plant)
Explanation:
Independent variable of an experiment is the variable that is changed or manipulated by the experimenter in order to bring about a measurable response. In this experiment where Sherri wanted to test what fertilizer worked best on her tomato plants. She used 4 different brands of fertilizer. Hence, the FERTILIZER is the independent variable
On the other hand, the dependent variable is the variable that is measured in the experiment. It is the variable that responds to the independent variable. In this experiment, the DAILY PLANT GROWTH is the dependent variable.
Constants are variables that are kept unchanged or constant throughout the experiment. In this case, the constants or controlled variables are: : How much water they receive daily, How much sunlight the plants receive, type of plant (tomato plant)
The independent variable in Sherri's experiment is the type of fertilizer used. The dependent variable is the daily growth of the plants. The controlled variables include the type of plant, the amount of sunlight received, and the amount of water given daily.
In this experiment, the independent variable is the fertilizer given to each plant. This is because the type of fertilizer is what is being changed or manipulated in this experiment to observe the potential changes or effects on the plants.
The dependent variable in this scenario is the daily plant growth. It is called 'dependent' because its value might change depending on the effect of the independent variable (the fertilizer).
The controlled variables for the experiment are the type of plant, how much sunlight the plants receive, and how much water they receive daily. These are conditions that were kept the same for each plant to ensure that the only difference between the plants was the type of fertilizer used.
