Answer:
The earliest known life-forms are putative fossilized microorganisms, found in hydrothermal vent precipitates, that may have lived as early as 4.28 Gya (billion years ago), relatively soon after the oceans formed 4.41 Gya, and not long after the formation of the Earth 4.54 Gya.

10. There is a 2 in 4 probability their offspring will be Heterozygous for ear lobes
Explanation:
So if pendulous ear lobes are (E) and adherrent ear lobes are (e)
Its important to regonize that a man who has pendulous ear lobes whose mother had adherrent ear lobes should be written as (Ee) seeing as how the pendulous ear lobes are dominant over adherrent ear lobes
also, recognize that while using a punnet square you have a set of two alleles
Note: The husband is Heterozygous
The Husbands: (Ee) pendulous ear lobes
The Wifes: (ee) adherrent ear lobes
Heterozygous just means they can either pass on the pendulous ear lobes or adherrent ear lobes so their alleles look like (Ee)
you can begin the problem by using a punnet square:
e e
E Ee Ee
e ee ee
Meiosis, also called reduction division, is cell division necessary for the formation of gametes (sperm and eggs). In this type of division, diploid cell (with two sets of chromosomes) forms haploid cells (with a single set of chromosomes). The haploid number is produced during the meiosis I (anaphase I) when homologues pairs, not individual chromosomes, separate.
It takes longer, especially when you’re first getting started and you’re not in a rhythm. You can find lots of good recipes that don’t require manual kneading, but you still have to set everything up, measure it out, and pay attention to rising times.
There’s more work involved: again, kneading, watching rising times, etc. (most recipes really aren’t much work, however, so don’t let this scare you—it’s just more work than going to the store and banging a loaf on the register counter)

The most important one: consistency. Home-baked bread (or anything, for that matter) doesn’t always turn out the same…especially when you’re just getting started. With practice and repetition you could become an expert, and make the perfect loaf of bread in your sleep and it will taste the same every time. But baking bread is a delicate art as well as a science. The end result can be impacted by weather, temperature changes in your kitchen, the functionality of your oven, the number of seconds or minutes you spend kneading or mixing the dough, the quality of your flour. So while all in all, with a good recipe, you’ll get a good result every time, you might not expect to get the same result every time.
It can have all of the measures except 89 because an Acute angle is 45 degrees and less.
