10. If one strand of DNA is
TCAAAGCTGC, what is the
complementary strand of DNA on the
other side?
Answer:
Explanation:As previously stated, DNA is a macromolecule that's made up of individual subunits called nucleotides. Each nucleotide has three parts:
Brought to you by Sciencing
A deoxyribose sugar.
A phosphate group.
A nitrogenous base.
DNA nucleotides can contain one of four nitrogenous bases. These bases are adenine (A), thymine (T), guanine (G) and cytosine (C).
These nucleotides come together to form long chains known as DNA strands. Two complementary DNA strands bond to each other in what looks like a ladder before winding into the double helix form.
The two strands are held together through hydrogen bonds that form between the nitrogenous bases. Adenine (A) forms bonds with thymine (T) while cytosine (C) forms bonds with guanine (G); A only ever pairs with T, and C only ever pairs with G.
Complementary Definition (Biology)
In biology, specifically in terms of genetics and DNA, complementary means that the polynucleotide strand paired with the second polynucleotide strand has a nitrogenous base sequence that is the reverse complement, or the pair, of the other strand.
Every part of your DNA codes for proteins.
1. True
2. False
The portion of the genome that codes for a protein or an RNA is referred to as a gene. Those genes that code for proteins are composed of tri-nucleotide units called codons, each coding for a single amino acid. False
Its FALSEEEEEEEEEEEE!!!!!

Amagnetwith alength of 10cmwasgiven to Meera and shewas told to break themagnetinto3 pieces.Before breaking the magnet had 1 north and 1 south pole. How many north and south poles will the magnets now havetotally in all the 3 broken pieces?
Answer:
3 North poles and 3 South poles
Explanation:
A magnet is a piece of object that produces a magnetic field outside itself. A magnet has a north pole and a south pole. Similar poles repel each other, while opposite poles attract each other.
If a magnet of 10cm is broken into 3 pieces, we will have 3 pieces of magnet. Breaking a magnet does not destroy the properties of the magnet. Rather, each piece becomes a full magnet with both north and south poles.
Breaking a 10cm magnet will give us 3 magnets with 3 north and 3 south poles with equal pole strength.

One side of a DNA molecule has the following sequence of nitrogen bases GGTACTTACGCA. What would be the complementary side’s bases? How many amino acids would that sequence code for?
Answer: The arrangement of these nitrogen bases contains the code for
genetic traits. These bases are arranged in a particular
sequence, such as TGCATTCA. The sequences of DNA can vary
from several hundred bases to a million or more bases.
Explanation: put this and my teacher said amazing
The complementary side’s bases if one side of a DNA molecule has the following sequence of nitrogen bases GGTACTTACGCA are: CCTGAAATGCGT.
What is the complementary sequence?Thus, the complementary nitrogen base sequence of GGTACTTACGCA is CCTGAAATGCGT. It is because the complementary nitrogen bases pair up: A always pairs with T, and C always pairs with G.
The sequence codes for 4 amino acids. Every three nitrogen bases code for one amino acid. So, since there are 12 nitrogen bases, the sequence codes for 12/3 = 4 amino acids.
To determine the number of amino acids coded by this sequence, first note that a codon consists of three nucleotide bases, and each codon corresponds to one amino acid. The sequence has 12 bases, so there are 4 codons: GGT, ACT, TAC, and GCA. Since each codon codes for one amino acid, this sequence would code for 4 amino acids.

how does natural selection affect different variation of the same species?
Answer:
Natural selection can lead to speciation, where one species gives rise to a new and distinctly different species.
Explanation:
Through this process of natural selection, favorable traits are transmitted through generations. It is one of the processes that drives evolution and helps to explain the diversity of life on Earth.

Metaphase - M for middle; they line up in the middle
Anaphase - The begin to split and be pulled apart
Telophase - They are at their opposite ends, but not yet their own cells
Nonpoint source pollution is difficult to control because it _______. a. comes from a direct point of origin b. comes from a variety of sources c. remains the same over time d. none of the above Please select the best answer from the choices provided
Answer:The correct option is B.
comes from a variety of sources
Explanation:
Nonpoint source pollution is a form of pollution that is generated from different sources which include land runoff, rainfall, seepage, deposits from atmosphere and drainage, and seepage. Nonpoint source pollution is cause from rain falls as a result, its water flow through the ground , therefore the runoff wash and pick the pollutants and discharge them into water bodies. Nonpoint source polution is very difficult to control because it's originate from different type of sources.
Answer:
b. comes from a variety of sources

In the scenario above, Red hair (R) is dominant to blonde hair (r). If two parents are
heterozygous for red hair, what percentage of their offspring will have red hair and what
percentage will have blonde?
Answer:
75% of the offspring will have red hair and 25% will have blonde hair.
Explanation:
Since red is dominent but heterozygous it will be represented like Rr. Since both parents have that put it on a punnet square to get 75% red and 25% white.

What is Solar energy?
Solar energy is the radiant heat and light from the Sun that is captured by a variety of technologies, including solar architecture, solar thermal energy (including solar water heating), and solar power to produce electricity.
It is a crucial source of renewable energy, and depending on how solar energy is captured, distributed, or transformed into solar power, its technologies are often classified as passive solar or active solar. Utilizing photovoltaic systems, concentrated solar electricity.
A building's orientation toward the Sun, the use of materials with favorable thermal mass or light-dispersing qualities, and the creation of naturally ventilated rooms are all examples of passive solar approaches.
Therefore, The ice cubes represents the solar energy.
