Answer:
Modern human are called as Homo sapiens.
Explanation: Following are the characteristics of the modern human skull-
i) They have projecting nose bone and comparatively small face.
ii) Eye sockets are square in shape.
iii) the neck muscles are reduced.
iv)The skull is round at the back.
v) Their cranial capacity is 1350 cc. Earlier they had a cranial capacity of 1500 cc.
vi) There has no narrow constriction behind the orbits.
Here's what we know:
10,000 individuals
6,840 individuals have blood type AA
2,860 individuals have blood type AB
300 individuals have blood type BB
AA genotype frequency: 68.4%
AB genotype frequency: 28.6%
BB genotype frequency: 3%
The A allele occurs 6,840 * 2 + 2,860 * 1 = <span>16,540 times, which is a frequency of 82.7%, meaning the B allele occurs 3,460 times, which is a frequency of 17.3%. In the next generation, 3%, or 750, individuals would have blood type BB.</span>
Answer:
Ss for the top and TT and Tt
Explanation:
Answer:over time as our evidence improves. The more experiments we do, and the more data we collect, the better our scientific ideas become.
Explanation:
Answer:Phaeophyta--Described as "hairy" in appearance produce alginic acid, which can be used as a thickening agent.
Rhodophyta ;are utilized commercially to produce carrageenan and can photosynthesize at depths greater than 10 meters
Chlorophyta;Considered the progenitor of land plants, have 18S rRNA sequences comparable to plants
Chrysophyta;The is a diverse group that includes the diatoms, a major component of phytoplankton
Explanation:algae are a diverse group of organisms with majority of them living in water and a few on land. They are green and contains chlorophyll.they also contains phycobillins pigments.
Chlorophyta are green algae that exist in water habitat an example is Chlamydomanas reinhardi.they have similar structures with higher plants such as chlorophyll, cellulose cell wall and stores food as starch.
The chrysophyta includes diatoms.diatoms have a cell wall composed of pectin and deposits of silica. They may occur in large deposit as diatomaceous earth.
Phaeophyta--are brown algae. An example is sea weed they are found in deeper ocean waters. Sea weed has a thallus which branches into a basal holdfast that aids attachment to rocks.their blade allows the plant to float
Rhodophyta are algae which are sometimes Unicellular in form they have a characteristic red color due to the presence of phycoerythrin along with phycocyanin, chlorophyll.they are used as source of algar for microorganism culture.
