Answer:

Homo species have differences in brachial index, face and teeth size as compared with australopithecines.

Explanation:

Australopithecines were found in pleistoocene era and adapted to the bipedal locomotion but shows differences in walking style as compared to early homo species. They have large brachial index. The postcanines were large but incisors and canines were small.

Early homo species were found around 2 million years ago. They shows bipedal locomotion with different walking styles. The brachial index of early homo species was small as compared with the australopithecines. The post canines were small but incisors and canines were large.

What can two countries with similar gdp’s have greatly differing average levels of material well being
kati45 [8]

Answer:

Two countries with a very similar gdps can have great difference in the average material well being when the two countries have wide difference in their population and in their national debts.

Explanation:

The Gross domestic product of a country shows the overall asset a country has without removing the national debt. This average wellbeing if the citizen in a country depends on the per capita income of that country, the higher the PCI the better is the expected wellbeing. The cpi is calculated by dividing the gdp by the population in the country, therefore even when two countries have the same gdp, but very huge difference in their population, it will lead to different per capita income. The country with the smaller population will have higher per capita income and better material wellbeing.

Secondly, when the countries have the same gdp and population, the difference in their national debt will lead to difference in available material wellbeing in the countries.

Somatic cells of roundworms have four individual chromosomes per cell. How many chromosomes would you expect to find in an ovum
andrezito [222]

Answer:

2 chromosomes

Explanation:

The cell of an eukaryotic organism like roundworm contains the Nucleus, which harbors the genetic material embedded in the chromosome. The number of chromosomes of that organism is contained in each cell.

Somatic cells, also called body cells, are all other cells asides sperm and eggs, that form the tissues and organs of an organism. Somatic cells are usually diploid i.e two sets of chromosomes from each parent. In this question, the roundworm has 4 chromosomes in its somatic cell.

The reproductive cells or sex cells (sperm and eggs) of an organism always result from meiotic division of specialized cells.

Since meiosis is a kind of division that results in cells with their chromosome number reduced by half (haploid), it therefore means that the ovum and sperm cell will be expected to contain 2 chromosomes each.

This way, when fertilization occurs (sperm and egg fusion), the resulting zygote, which will eventually develop into an adult organism, will have 4 chromosomes.

Svetllana [295]

Answer:

A. Cadherins in desmosomes would no longer be anchored to intermediate filaments

Explanation:

Cadherins are Ca dependent molecules (proteins) that are involved in cell-cell adhesion (they are type of cell adhesion molecule-CAM). Cadherins are composed of: a small cytoplasmic component, a transmembrane component, and the extra-cellular part.

There are types of cadherins called desmosomal cadherins which are involved in the formation of desmosomes (structure for cell-cell adhesion) and they bind to linker proteins and keratin intermediate filaments.
