What are the methods of waste disposal ? Write in briefly.​

Answers

Answer:

Methods of waste disposal are :-

Biogas plant: - Biodegradable material is used to produce biogas and manure.

Sewage treatment plant: The drain water is treated at plants before adding it to river.

Land filings: - The waste are buried in low-lying areas and compacted with bulldozers.

Composting: - Organic waste are filled in compost pit to make compost for plants.

Recycle: - This means that you collect plastic, paper, glass and metal items and recycle these materials to make required things instead of synthesizing or extracting fresh plastic, paper, glass or metal. In order to recycle, we first need to segregate our wastes so that the material that can be recycled is not dumped along with other wastes.

Reuse: - This is actually even better than recycling because the process of recycling uses some energy. In the ‘reuse’ strategy, you simply use things again and again. Instead of throwing away used envelopes, you can reverse it and use it again. The plastic bottles in which you buy various food-items like jam or pickle can be used for storing things in the kitchen.

Refuse: -This means to say No to things people offer you that you do not need. Refuse to buy products that can harm you and the environment, say No to single-use plastic carry bags.

Repurpose - This means when a product can no more be used for the original purpose, think carefully and use it for some other useful purpose. For example, cracked crockery, or cups with broken handles can be used to grow small plants and as feeding vessels for birds.

Match each organelle with the main life function(s) it helps the cell perform. Each basic function of life can be used more
than once, and many organelles will have more than one possible answer. Choose one answer only,

Organelle list - nucleus, mitochondria, golgi apparatus, endoplasmic reticulum, ribosomes, lysosomes, vacuoles, cell membrane, chloroplast, cell wall


The answer could either be 1. reproduction 2. interaction with the environment 3. growth 4. uses energy 5. waste production (each function can be used more than once)

Answers

Answer:

The correct answer is -

nucleus - reproduction, mitochondria- reproduction, golgi apparatus - waste production, endoplasmic reticulum - growth, ribosomes - growth, lysosomes- waste production, vacuoles - growth, cell membrane - interaction with the environment, chloroplast - uses energy, cell wall - interaction with the environment

Explanation:

A Cell has various organelles with more than one generic function such as the nucleus not just play role in cell reproduction but also plays role in regulating other organelle and cell growth by transcription. Mitochondria produces and provides energy for many functions such as growth, reproduction and substance transport.

Golgi apparatus package proteins and wastes to transfer them out of the cell. The ndoplasmic reticulum modifies the protein produced by ribosomes and helps in growth of the cell. Lysosomes digest waste and cell debris by lysosomal vesicles. Cell membrane and cell wall interact with outer environement.

Answers

Answer:

Z

Explanation:

The first stage of cellular respiration is called GLYCOLYSIS, where glucose is broken down into pyruvate. Because glycolysis occurs irrespective of whether there is oxygen or not, it occurs in all organisms. Hence, glycolysis occurs in the CYTOPLASM of their cell.

In this question, a diagram was given as an attachment. In the diagram, letters W, X, Y amd Z are used to represent organelles in the cell. Letter Z represents the cytoplasm, hence, the first stage of cellular respiration takes place in Z.

Answers

Answer:

both characteristic represent mitosis

The characteristics of certain cell divisions are described in the following table, the two characteristics represent is both characteristics represent mitosis.

What is mitosis easy definition?

Mitosis is a Method in which a single cell divides into two identical daughter cells (cell division).

In this cell divides once to form two identical cells. The major purpose of mitosis is for growth and to replace worn out cells.

Thus, option "B" is correct, Both characteristics represent mitosis.

You treat a sample of DNA with DNase and run the digested fragments out on an electrophoretic gel. You found mostly long fragments. What can you conclude about this sample of DNA

Answers

Answer:

the sample contains mostly heterochromatin  

Explanation:

Heterochromatin refers to a highly condensed state of DNA, whereas euchromatin is lightly packed. It is for that reason that heterochromatin is associated with a transcriptionally inactive state, whereas euchromatin regions are active for transcription. Heterochromatin regions resist DNases because these enzymes don't cut DNA randomly, but they show sequence preference. In consequence, highly repetitive DNA heterochromatin regions (e.g., centromeres, telomeres, etc) may exhibit resistance to DNA cleavage.

From deep to superficial, the order of the strata of the epidermis is corneum - granulosum - lucidum - spinosum - basale. spinosum - granulosum - basale - lucidum - corneum. basale - granulosum - spinosum - lucidum - corneum. corneum - lucidum - granulosum - spinosum - basale. basale - spinosum - granulosum - lucidum - corneum.

Answers

Answer:

basale - spinosum - granulosum - lucidum - corneum.  

Explanation:

The order of strata in the epidermis:

Basale: it is the deepest stratum. It has one layer of cells called keratinocytes, which are stem cells for the epidermis.Spinosum: The keratinocytes in this layer have spiny shapes. They synthesize cytokeratin and lipids. In this layer, we can also find macrophages.Granulosum: The keratinocytes of the previous layer ascend and synthesize keratohyalin, which is in granules. The keratohyalin helps to join keratin filaments. Also, the cells release the lipids synthesized in the previous layer, and they form a barrier that stops dehydration.Lucidum: it is only on thick skin, like the one in the sole of the feet. The keratinocytes in this layer have expelled the nucleus and now are dead cells. The keratinocytes have a flat shape and form a thin layer.Corneum: it is the most superficial layer. It is made of dead keratinocytes filled with keratin in their cytoplasm. It is a thick layer that suffers desquamation when new dead cells filled with keratin ascend from the previous layer.
