Answer:
Point source pollution:
- Oil from a garage that is released into water
Non-point source pollution:
<u>Explanation:</u>
According to <u>United States Environmental Protection Agency (EPA)</u> regulations, <u>point source pollution</u> is a type of pollution in which contaminant is released into the environment from an <u>easily identified source</u>. In the examples given above, smoke from a factory, sewage, and oil effluents are coming from easily identifiable sources.
On the other hand, a <u>non-point source of pollution</u> is the release of contaminant in the environment <u>through diffused or unidentifiable sources</u>. In the examples given above, smoke from cars could be stated as non-point sources of pollution because vehicles are in a continously moving state.
E p = m · g · h
E p ( book ) = 0.35 kg · 9.8 m/s² · 2 m = 6.86 J
E p ( picture frame ) = 6.86 J
( same gravitational potential energy as the book )
6.86 = 0.5 · 9.8 · h
6.86 = 4.9 h
h = 6.86 : 4.9
h = 1.4 m
Answer:<span> ... to a height of 1.4 m.</span>
Answer:
D. nothing of all
Explanation:
Karyotype is defined as the process through which photographs of chromosomes are taken and chromosomal structure is studied.
Karyotype do not give any information regarding gender or genes location as karyotype only give information about the number of chromosomes, size or length of chromosome, banding pattern, and the position of the centromeres.
Karyotypes can give information such as chromosomal disorder, taxonomic relationships, and cellular function.
Hence, the correct answer is "D. nothing of all".
Answer: Each chromosome actually consists of two sister chromatids, which are joined together at a centromere. ... During this process, sister chromatids separate from each other and move to opposite poles of the cell. This happens in four phases, called prophase, metaphase, anaphase, and telophase. Homologous chromosomes are two pieces of DNA within a diploid organism which carry the same genes, one from each parental source. In simpler terms, both of your parents provide a complete genome. Each parent provides the same 23 chromosomes, which encode the same genes. Sister chromatids are two identical copies of the same chromosome formed by DNA replication, attached to each other by a structure called the centromere. During cell division, they are separated from each other, and each daughter cell receives one copy of the chromosome. Spindle fibers are filaments that form the mitotic spindle in cell division, i.e. mitosis and meiosis. They are chiefly involved in moving and segregating the chromosomes during nuclear division. Spindle fibers are made up of microtubules. In meiosis. Each pair of chromosomes—called a tetrad, or a bivalent—consists of four chromatids. At this point, the homologous chromosomes exchange genetic material by the process of crossing over (see linkage group). The tetrad occurs during the first phase of meiosis. It is the foursome of chromatids that forms when replicated homologous chromosomes align. It must be formed for crossing over to occur. It is broken apart when the homologous chromosomes separate in meiosis I.
