Answer:

Favorable geographic as well as environmental conditions.

Explanation:

Human settlement flourish at that place where favorable geographic as well as environmental conditions are available such as availability of water , a suitable climate, fertile land etc. these resources attracts human to settle there due to availability of basic needs. If these natural resources are not present in a location so people does not came to settle there.

Answer:

Explanation:The phospholipid bilayer formed by these interactions makes a good barrier between the interior and exterior of the cell, because water and other polar or charged substances cannot easily cross the hydrophobic core of the membrane. Can water cross the plasma membrane at all?

It also helps the cell move things in and out. The cell membrane is made of what is called a phospholipid bilayer, which means it has two layers of phospholipids. ... This allows the phosphates to be exposed to water, either in the cell or the environment, while the lipids are protected from water Lipids are essential for all life on Earth. They play many important roles in maintaining the health of an organism. Arguably the most important function lipids perform is as the building blocks of cellular membranes. Other functions include energy storage, insulation, cellular communication and protection.Large quantities of water molecules constantly move across cell membranes by simple diffusion, often facilitated by movement through membrane proteins, including aquaporins. In general, net movement of water into or out of cells is negligible.

Explanation:

Contrary to popular belief, the seasons are not determined by the earth's distance from the sun. The seasons are actually caused by the earth's tilted axis. Because the axis is tilted, when the Northern Hemisphere is tilted towards the sun, it's warm.

Sociocultural means combining social and cultural factors.

The focus of study in anthropology is an example of sociocultural.

The theory of sociocultural perspective explains how behaviors of individuals are affected by their social and cultural factors.

Answer:

c

Explanation:

During Precambrian time, The amount of oxygen increased in the earth's atmosphere. Therefore, option C is correct.

From roughly 4.6 billion years ago, when Earth first started to form, to the start of the Cambrian Period, 541 million years ago, is the Precambrian Period. It is the earliest era which is followed by the Cambrian period.

Large objects bombarded the Precambrian Earth, the crust was split into the first continents and ocean basins, crustal plates were mobilized, the atmosphere changed from reducing to oxidizing, and early life began and evolved. Climate and geologic events are responsible for the end of this period.

During this period, the amount of oxygen increased rapidly. Therefore, option C is correct.

★ People's awareness of the environmental changes brought about by industrialization

Explanation:

Hope you have a great day :)

Industrial Revolution was the phenomenon that led to the application of ethical standards to relationships between people and their environment.

Environmental ethics is a current philosophical thought that originated after the Industrial Revolution as a result of the environmental damage that had been done to different ecosystems and species as a result of the industrial revolution.

Environmental ethics proposes a modification in the relationships between human beings and their environment from a moral perspective to ensure the preservation or restoration of said natural values.

Answer:

c. A chromosomal mutation can change the total number of chromosomes in the cell.

Explanation:

A gene mutation affects a single gene, and replication error is the main cause of gene mutation. A chromosomal mutation affects one part of chromosome or full chromosome. error in meiosis is the main cause of chromosomal mutation. Both mutations are responsible for a change in DNA. A chromosomal mutation leads to the change in total number of chromosomes in the cell.

Explanation:

Answer:

A, This is the case of selective pressure of environmental factors like snow, due to which favored the expression of the allele that formed white coat phenotype. This is not a Hardy-Weinberg principle, in which no selective pressure is applied. The relative frequencies of the alleles change in the gene pool, due to selective pressure, and the expressed alleles are often significant for survival in those conditions.

b,HW equilibrium means no selective pressures like the long, snowy winters selectively favoring the white coat phenotype over the other coat phenotypes. Selective pressures change the relative frequencies of the alleles in the gene pool. It also means the population does not have either immigration or emigration to change the ratios of alleles in the gene pool The Hardy-Weinberg principle of genetic equilibrium tells us what to expect when a sexually reproducing population has no selection pressure, no gene flow, no nonrandom mating, not even genetic drift.

Answer:

The correct phases are S phase, prophase, anaphase.  

Explanation:

The cell cycle, the sequence of events spanning the period from the completion of one cell division to the end of the next division, involves both the division of the cell nucleus (karyokinesis) and the division of the cytoplasm (cytokinesis). S phase, the next section of the interface, is marked by a dramatic increase in DNA synthesis and the synthesis of histones which are major cellular proteins bound to DNA. The cell is preparing for the start of mitosis. Chromosomes duplicate lengthwise, and each chromosome consists of two identical "chromatids."During prophase, the degree of packing of the chromatin increases, so the chromosomes become shorter and thicker and the centromeres begin to become visible. Each of the chromosomes, due to its duplication in S phase, is made up of two identical chromatids, called sister chromatids. Anaphase is the short phase, the sister chromatids begin to separate and migrate to the poles. Once the two chromatids separate, each is called a chromosome.
