Which of the following is not a category of sedimentary rocks? *
Calstic
Organic
Foliated
Chemical
Sedimentary rocks are the rock formation from the parental rocks. clastic, chemical, and organic are the types of sedimentary rock but not foliated. Thus, option C is correct.
What are the types of sedimentary rocks?Sedimentary rocks form from the accumulation of the sediments from the deposits of pre-existing rocks over time. The sedimentary rocks are of four types namely biochemical, clastic, chemical, and organic.
The biochemical and the organic rocks were formed from the living or the biotic factors that got accumulated over time as sediments. It includes biochemical limestones, coal, and diatomite.
The chemical rocks were formed due to the reaction and desolvation of the chemicals with the water like rock salt, dolomites, etc. On the other hand, the Foliated are types of metamorphic rocks that have a strip-like appearance.
Therefore, option C. Foliated is not a type of sedimentary rock.

The grey matter includes neural cells, dendrites, and axon terminals, whilst white count number consists of axons and myelin.
How can you inform the difference between grey and white remember and the brain?The white rely takes place in both the brain and spinal wire. but, gray be counted is a large part of the mind. the main difference among white rely and grey rely is that white count number mainly incorporates myelinated axons and gray matter specifically consists of cells, axon terminals, and dendrites.
What is the grey and white remember of the spine?Gray be counted is a grey area across the critical anxious machine of the CNS. A combination of neuron bodies of interneurons and motor neurons and neuroglia. Synapses from grey matter.

which organelle does the skeletal system connect to and why?
Answer:
Muscles connect to your skeleton and they contract and move the skeleton along. Your skeletal system is made up of cartilage and calcified bone that work together. They help the process of movement happen in a smoother manner. The calcified bones of your skeleton also work with the circulatory system.
Answer:
Organelles of a skeletal muscle cell contain the same organelles as other animal cells, with the addition of myofibrils. Muscle fibers within the skeletal cell are known as myofibers. These organelles allow skeletal muscle cells to contract. Skeletal muscle cells do contain more mitochondria than other cells, because muscle cells require more energy and must convert more glucose. Skeletal muscle cells also differ from other cells because of the myofilaments within the myofibrils. Within these filaments are proteins known as myosin and actin. The special filaments enable the skeletal muscles to contract. The myofibrils within skeletal muscle cells are divided into units known as sarcomeres, which are the units of skeletal muscle cell contraction.

Evaluate the pros and cons of using an NPK fertilizer, a natural compost, and lime on a field with substantial amounts of clay and humus and with a low pH of 3, which is to be planted with a legume crop.
Answer:
Leaching of nutrients occur.
Explanation:
NPK fertilizers are applied to the field all over the world because it has a good effect on the growth and development of plants but it has also some environmental effects such as leaching which pollutes water bodies whereas natural compost is good for the plants as well as for the soil organisms but its breakdown is very slow and it is not readily available to the plants. Lime is also very good for the soil having low pH because lime is basic in nature and it increases the pH of the soil.

Answer:
Denaturing – when the double-stranded template DNA is heated to separate it into two single strands. Annealing – when the temperature is lowered to enable the DNA primers to attach to the template DNA. Extending – when the temperature is raised and the new strand of DNA is made by the Taq polymerase enzyme

The figures below refer to a herd of water buffalo.
Birth rate = 35
Death rate = 7
Immigration = 4
Emigration = 17
What is this population growth?
population increases by 41
population decreases by 15
population increases by 15
population decreases by 24
Answer: population increases by 15
Explanation:
The population growth will be calculated by adding the Natural Increase in population plus the Net In-Migration. This will be:
Natural increase = Birth - Death rate
= 35 - 7
= 28
Net-In-Migration = Immigration - Emigration
= 4 - 17
= -13
Therefore, population growth will be:
= 28 - 13
= 15
Therefore, population increases by 15
In the given case, the population growth - population increases by 15
Population growthPopulation growth is the increase in the number of people in a population or the change in the number of individuals of a species in an area over time.It can be calculated by the difference between the addition of individuals and the removal of individuals from the populationAddition can be by immigration or birth whereas removal can be emigration or deathSo growth = (birth rate + immigration) - (death rate + emigration)
Then, population growth = (35+4) - (7+17)
= 39 - 24
= 15
Thus, In the given case, the population growth - population increases by 15

Look at the albino whale people have named Migaloo. The white color is the result of mutations in the genes that code for the proteins responsible for skin color. Is Migaloo’s white color likely to be an advantage in its current environment? Explain your answer.
No, the white color of Migaloo is not most likely an advantage in its current environment. This is because white is the color that is easily perceived by predators.
What is the Mutation?A mutation may be defined as sudden, stable, and inheritable changes in the genetic material of an organism. An organism that undergoes an event of mutation is known as a Mutant. The agents of mutation are known as mutagens.
White color is easily perceived by predators as compared to black, brown, grey, etc. So, it somehow reduces the fitness and survivability of Migaloo. This white color is the result of mutations in the genes that code for the proteins responsible for skin color.
Therefore, the white color of Migaloo is not most likely an advantage in its current environment.

Some fruits are especially well suited for DNA extractions due to their multiple sets of chromosomes. Strawberries are octoploid, which means they have eight copies of each chromosome. In comparison, human cells are diploid, which means they contain two copies of each chromosome.
