Answer:

cyanobacteria

Explanation:

Cyanobacteria are considered one of the first photosynthetic life forms on the planet. They are estimated to have appeared approximately three billion years ago. Given the date of fossils that prove the existence of this organism in primitive times, it is believed that cyanobacteria were the main responsible for releasing oxygen in our atmosphere, making the earth a habitable planet.

Use the information from Parts B and C to solve this problem. If a rabbit of genotype AaBb is bred to a rabbit of genotype AaBb,
Kipish [7]

The question is incomplete and the complete question is

Suppose that ear length in rabbits is controlled by two additive genes, each of which has two alleles. A true-breeding female (aabb) with 6-cm ears is mated to a true-breeding male (AABB) with 16-cm ears.

Answer:

AABb or AaBB

Explanation:

We know that,

aabb genotype - 6 cm

AABB genotype- 16-cm

To calculate the length of earlobe contributed by each allele in a genotype is :

1. length of aabb/4 or 6/4= 1.5 cm (a and b contribute for 1.5 cm each)

2. Length of AABB/4 or 16/4= 4 cm (A and B contribute for 4 cm each)

Now to have the earlobe to be 13.5 cm long then the genotype must be

13.5 = 4+4+4+1.5 or A+A+B+b or A+a+B+B

Therefore, the genotype will be-either AABb or AaBB

Put the fats in order from the one that contains the greatest percentage of saturated fatty acids (1) to the one that contains t
olganol [36]

Answer:coconut oil, butter, palm oil, olive oil, canola oil.

Explanation: .

A saturated fat one whose fatty acid chains have all or predominantly single bonds. A fat is made of two kinds of smaller molecules which are glycerol and fatty acids. Fats are made of long chains of carbon (C) atoms while some carbon atoms are linked by single bonds (-C-C-) bonds others are linked by double bonds (-C=C-). These Double bonds will react with hydrogen to form single bonds causing them to be SATURATED, because when the second bond is broken, each half of the bond is then saturated with a hydrogen atom.

In terms of saturated fats acids composition by percentage according to ChartsBin statistics collector team 2011, Fat Composition in different Cooking Oils, ChartsBin.com, palm oil is 14.192, coconut oil is 91.92 canola is 7.46,palm oil 51.57, butter 65%-68%.Here you can see that the order of saturated fats from the highest gives- Coconut,butter, palm oil,olive oil and Canola as the last
