Answer:
The value of the expression is as follows:
a = 10; B = 2.5; c = 7
Explanation:
a = 4B = 3 + c = 10
Step 1
split equation into parts, then we have
3 + c = 10
c = 10 - 3
c = 7 (the value of c is 7)
Step 2
Rewrite equation as a = 4B = 10, then split again
4B = 10
Then, B = 10➗ 4
B = 2.5 ( the value of B is 2.5)
Step 3
Take the last part of the equation
a = 10 (the value of a is 10)

Answer:
If all humans ate only meat, will require more land to grow food crops
Explanation:
1) Currently, over 60% of the world food crops are eaten by animals. Given that food crops are generally consumed more than meat in a proportion of 8:1, if all humans ate only meat, the amount of land required to grow food crops will have to be increased by at least 400%
2) Presently, animal agriculture makes use of 70% of lands allocated to agriculture, such that increasing the livestock by an extra 400% will lead to mass deforestation in order to produce livestock feeds
3) It is more costlier to produce livestock than to produce crops, which will make the availability and allocation of land essential for the raising of livestock in order to reduce costs, thereby taking more land.
The sporophyte of <u>whisk ferns</u> consists of evenly forking photosynthetic stems that lack roots and leaves.
Whisk ferns are the elementary and simplest vascular plants.
They contain small-sized protuberances which are called ' enations.'
In these plants, a vascular system is present in the center through which the transport of nutrients and other fluids takes place.
Moreover, roots and leaves are absent in these plants and are composed of forklike stems.
To put it simply, these plants have hair-like structures that are part of the rhizomes. These structures are called rhizoids.
