Answer:
because its energy reflects its changing
Explanation:
The answer is '<span>triploid cell'.

This occurs when two sperm nuclei reach the interior of a female gametophyte, where one sperm will fertilise the egg cell to form a zygote, whereas the other usually fuses with the binucleate central cell, forming a primary endosperm cell, effectively constituting an organism separate from the growing embryo. Approximately 70% of angiosperm species have polyploid endosperm cells which are typically triploid (containing three sets of chromosomes), but can vary widely from diploid(2n) to 15n.
Fossil Fuels Affect the Environment in the Following Ways:
1. When we burn coal, oil, and natural gas for fuel, too much carbon enters the atmosphere at one time. The carbon combines with oxygen to form carbon dioxide (CO2), a greenhouse gas. Greenhouse gases are contributing to global warming because they trap more of the Sun's energy in the Earth's atmosphere.
2. Due to the burning of Fossil Fuels, Some Poisonous Gases like Sulphur Dioxide, Nitrous Oxide, Methane and Carbon Dioxide, Which lead to Widespread Pollution in The Atmosphere.
3. This maybe a bit Difficult. Burning of Fossil Fuels causes Acid Rain. Acid rain is a rain or any other form of precipitation that is unusually acidic, meaning that it has elevated levels of hydrogen ions (low pH). It can have harmful effects on plants, aquatic animals and infrastructure. Acid rain is caused by emissions of sulfur dioxide and nitrogen oxide, which react with the water molecules in the atmosphere to produce acids.
4. It also releases Radioactive Substances or Radiances which Can be Pretty Explosive.
Hope this much helps!
The answer to this question is C
Answer:
C. Is a repeated sequence of DNA in a non- coding sequence
D. Can be composed of a variable number of repeats in different people
Explanation:
Short Tandem Repeats (STRs) are short DNA motifs, i.e., short nucleotide repeat units (generally 2-7 base pairs in size) that may have a different number of repeats among individuals (alleles). Polymorphic STR sequences are very useful genetic markers and therefore they are used for different purposes, e.g., for constructing genome linkage maps, identification of individuals and/or populations, paternity testing, etc. For example, in the USA, the Combined DNA Index System (CODIS) is a databank that stores different DNA profiles based on 13 core STR <em>loci</em> which are used in forensic identity testing.
