Answer:

Likewise, competition for food among deep-water fish that eat the same types of food will .

Explanation:

Natural selection will condemn all deep-sea fish to the same environment that conditions them, those that cannot develop gills will be exposed to extinction, this refers to the theory of the evolution of the fittest by Charles Darwin.

Answer:

A species of fish evolved over thousands of years to have gills that allowed the fish to swim deep in the sea. What’s the effect of this development on deep-water resources?

The fish developed the gills because of  

genetic modification

. Because the fish are now able to swim in deep water, their  

predators

in shallower water will have less food. Likewise, competition for food among deep-water fish that eat the same types of food will  

decrease

Answer:

Option B

Explanation:

Options

a. the sky..

b. the same thing I see..

c. a bunch of little people looking down at me..

 d. I have no idea

Solution -

Because of egocentrism, a child is unable to analyze and view a situation from the perspective of  other person. This is the second stage of Piaget's theory of cognitive development known as preoperational stage which generally starts at the age of 2 and last till the child is of age 7.  

According to Piaget, an egocentric child (beng unable to think of someone’s else perspective) believes that the other person will also see/feel/hear the same as he/she does him/herself.  

Hence, option B is correct

1) How is DNA condensed to form a chromosome?
Bumek [7]

Answer:

1) DNA is wrapped around histone proteins to form chromatin

2) The genes are the functional units, the segments between them are used for regulation

3) The genetic code is the language used, gene expression is how the cell uses the information, the activity of the genes.

Explanation:

1) DNA forms a DNA/protein complex called chromatin. It does this by wrapping around histone proteins. These histone proteins are usually present in the form of a nucleosome, which is a unit containing 2 copies of 4 histones (H2A, H2B, H3 and H4). The chromatin fibre at its most compact forms tightly coiled structures called chromosomes. These structures are only present during cell division. When the cell is in interphase (i.e. not dividing), the chromatin is not as tightly condensed, and instead the chromatin is more relaxed to allow the genes within to be expressed.

2) Genes are the functional units that the cell uses to make RNA and protein. The genes are first transcribed into RNA, which is processed and then translated into a polypeptide chain, which forms a complete protein that performs activities in the cell/tissue/organism. However, the whole genome does not form genes, there are regions that do not correspond to a gene. These regions are called "non-coding DNA" or sometimes even "junk DNA". However, that does not mean that these regions do not have important roles. The role of this DNA is usually in regulating the activity of the nearby genes. This DNA might contain important regulatory sequences such as promoters/enhancers/silencers that control how the gene is used by the cell, by for example, recruiting transcription factors or silencing proteins.

3) The genetic code is the language used by the cell. It explains how the cell can transcribe the information in the DNA, to RNA, process the RNA, and then translate the RNA into a polypeptide, and eventually a mature protein. In contrast, gene expression represents how the cell actually uses this information. Not all the genes are transcribed at the same time, instead, the activity of genes is carefully controlled to produce appropriate gene expression patterns, allowing the cell to properly perform its functions. Gene expression is hugely different between cells in an organism, for example the gene expression patterns of a muscle cell will  be hugely different to that of a blood cell.

Ratling [72]

Answer:

C) production of sperm and eggs

Explanation:

Sperms and eggs are the male and female gametes respectively. Formation of sperms and egg cells require meiotic cell division. Meiosis in sperm mother cells and egg mother cells reduces the chromosome number of half in the sperms and eggs. Meiosis also adds new gene combinations in these gametes by the process of crossing over.  

Mitosis cannot reduce the chromosome number to half in the sperms and eggs. Absence of crossing over in mitosis leads to the formation of genetically identical progeny cells from mitosis.  

Hence, mitosis can not form sperms and egg cells.  If it does, the sperms and egg cells would not have genetic variations and there would be doubling of chromosome number with each round of sexual reproduction.
