Answer:

The grams in 3 mol of KBr are: 357 grams.

Explanation:

We calculate the weight of 1 mol of KBr

Weight KBr = Weight K + Weight Br= 39,098grams +79,904grams= 119, 002 grams/mol

1 mol KBr--------------119, 002 grams

3 mol KBr-------------x= (3 mol KBr x119, 002 grams)/ 1 mol KBr= 357, 006 grams

How are protists different from plants​
kotegsom [21]

Answer/ explanation :

Protist can be multicellular or unicellular organisms

Plants are all multicellular and also exhibit cellular differentiation.

Protist can be autotroph, heterotrophic or decomposer

Plants are only autotrophs because they manufacture their own food through photosynthesis

Protists are microscopic, more diverse and abundant in nature

Plants are big and complex in nature

Nuclear DNA strands in plants are of higher complexity than those of protist

Plants require oxygen for cellular respiration process unlike protist which can be aerobic and some other species facultative anaerobic

Plants only can reproduce asexually through bulbs and tubers as in yam, potatoes while protists reproduce either sexually through meiosis or asexually through simple cell division.

1. In what ways does an organism’s mode of reproduction impact the diversity of its offspring? (Asexual vs. Sexual)
Katen [24]

Answer:

<u>Asexual reproduction</u> = An exact copy of the reproducer

<u>Sexual reproduction</u> = Genetic variation into the organism if a random mutation in the organism's DNA is transmitted to offspring.

Explanation:

Example of Asexual Reproduction diversity - A red apple has apple seeds. You plant the red apple seeds, and it grows up to be no different than the apple before it.

Sexual reproduction Example of diversity -Two parents are of different ethnicities. The female gets pregnant, but because of the different genetics from both of the parents, the child will inherit their genetics + some random mutation in the DNA.  

This impacts the diversity of the offspring because it can be an exact copy of the reproducer (Asexual), or significantly different with some similarities if the mode of reproduction was sexual.

I really hope this helps you! Please tell me if it did or not. Good luck with your assignment/exam/quiz!
