Subtract the sum of -25 and 38 from the sum of 52 and -21.​

Waterlogging occurs when there is too much water in a plant's root zone, which decreases the oxygen available to roots. Waterlogging can be a major constraint to plant growth and production and, under certain conditions, will cause plant death.

Answer:

Below mentioned points are the differences between the hydra and amoeba.

Budding in Hydra Binary fission in Amoeba

Asexual reproduction in which a novel organism enlarges from a bud in the parent. It is the kind of asexual reproduction in which the parent splits to give rise to two daughter organisms.

The bud or the latest organism remains attached to the parent and gets separated on maturation. Both the cytoplasm and the nucleus of the parent break up into two parts.

This bud is just a consequence of cells at one particular site. The parent replicates its genetic material and divides it equally between the two daughters.

Symmetric division Unsymmetrical division

Note: Budding is a form of asexual reproduction in which a new entity develops from several generative anatomical points of the mother organism. In some species, buds may be created from almost any point of the body, but in most cases, budding is limited to specific areas. Binary fission is the chief method of reproduction of prokaryotic organisms. In protists, binary fission is frequently differentiated into types like transverse or longitudinal on the basis of the alignment of cell separation.

Explanation:

Answer:

an = a + (n – 1)d.

Thx.....

Answer:

The nth term of an arithmetic sequence is given by. an = a + (n – 1)d. The number d is called the common difference because any two consecutive terms of an. arithmetic sequence differ by d, and it is found by subtracting any pair of terms an and. an+1.
