For meiosis, this is in anaphase I. For the separation of sister CHROMATIDS in mitosis, this is anaphase. Either way, the separation of two whole chromosomes or two chromatids within one whole chromosome takes place during anaphase. This occurs after metaphase and before telophase and cytokinesis.

Suppose that the farmer is growing rice crop. If he bought 5 kg seeds at Rs. 100 per kilogram, then how much net money will he g

ANEK [815]

Answer:

The net money the farmer will get

= Rs. 39,500

Explanation:

The farmer bought 5 kg seeds of rice at Rs. 100 per kg.

Cost price = 5 × 100 = Rs. 500

And he plants them and harvests 1000 kg of rice grains for sale, which he sells for Rs. 40 per kg

Selling price = 1000 × 40 = Rs. 40,000

The farmer's net profit

= (Selling Price) - (Cost Price) = 40,000 - 500 = Rs. 39,500

Hope this Helps!!!

In this type of tilling practice, the farmer

erik [133]

Answer:

No tilling agriculture.

Explanation:

No tilling farming is a type of agricultural practice where new crops are grown without spreading the soil through the tillage. This is a very age old practice used by farmers to replant new crops.

The advantages of using thus technique are many. It helps to kill hundreds of insects, it also helps in protecting the soil by leaving crop residue, apart from this is increases the irrigation productivity. Which is why farmers prefer no tilling agriculture mainly because the long term benefits of this technique are many.

Animal and Plant Cell Organelles Use the drop-down menus to determine where these organelles can be found. Ribosome Endoplasmic

rjkz [21]

Answer:

Animal Cell:

Ribosome, Endoplasmic reticulum, Golgi apparatus, small Vacuoles, Lysosomes, Mitochondria, Cell membrane, Cytoplasm.

Plant Cell:

Ribosome, Endoplasmic reticulum, Golgi apparatus, Cell wall, Big Vacuole, Lysosomes, Mitochondria, Cell membrane, Cytoplasm, Chloroplasts.

Explanation:

 Animal Cells Vegetable Cells

Cell wall NO YES

Vacuoles YES, Small and more than ones YES, Only one and big

Chloroplast NO YES

Plasmatic membrane YES YES

Mitochondria YES YES

Lysosomes YES YES

Endoplasmic reticulum YES YES

Golgi apparatus YES YES

Cytoplasm YES YES

Ribosome YES YES

Both the animal and plant cells are eukaryotic. They carry their genetic material in the nucleus and mitochondria. Organelles are located in the cytosol, and both of them are surrounded by a protector cell membrane.

However, they have some differences:

Cell wall: A rigid structure that provides support and protection.

Animal cells do not have a cell wall. They are only surrounded by the cell membrane, which is flexible, so they can adopt different shapes.
Plant cells have a wall, so their shape is usually prismatic and regular. The cell wall is composed mainly of cellulose.

Chloroplast: these are organelles that accumulate chlorophyll.

Animal cells do not have chloroplasts because they do not photosynthesize.
Plant cells have chloroplasts, and they are in charge of the photosynthesis process that allows plants to release oxygen. These organelles use solar light as the source of energy.

Vacuoles:

Animal cells have many and small vacuoles whose function is to store water, ions, and waste intracellular substances.

Plant cells have a unique big-sized vacuole that might occupy almost 90% of the cell. Their principal function is to store water and keep the turgidity. When the vacuole gets empty, the plant loses rigidity.

Other differences are:

The animal cell has centrioles, while the vegetable cell does not.

Plasmodium, chromoplasts, and glyoxysomes are present in the vegetable cell but not in the animal cell.

Why might parasitic roots have developed in plants like the mistletoe?

Ganezh [65]

Answer:

Mistletoe is a parasite – it steals water and nutrients from trees. Technically, it is a “hemiparasite”, which means that it can generate some of its own resources through photosynthesis – it just needs that energetic kick from the sun to fuel the biological siege and subsequent invasion of the tree

Why does lack of oxygen result in the halt of atp synthesis??

dsp73

Because the chain will begin to shut down and will no longer pump [H+] (hydrogen ions) across the membrane; thus, the proton gradient can not be maintained.

:) I hope this answers your question!
