how are Metamorphic rocks with fine grains made and how did the composition of the Earth’s atmosphere cause changes to form the rock over time.
Answers
Answer:
A rock is a naturally formed, non-living Earth material. Rocks are made of minerals. ... A rock may be made of only one type of mineral. More often rocks are made of a mixture of different minerals.
Metamorphic rocks (changed rocks) are made when existing rocks are subjected to high temperatures and high pressures for long periods of time. Metamorphism (meta = change, morph = form) happens when molten rock intrudes other rocks and bakes the contact zone where the molten rock touches the preexisting rock. Metamorphism also happens when rocks are buried deeply during the process of mountain building. The kind of metamorphic rock made depends on the kind of original rock; for example, sandstone is turned to quartzite, shale is turned to slate, and limestone is turned to marble.
Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering.
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?
Answers
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.

What is the function of the surface protein on the influenza virus?
Answers
Answer:
A virus surface proteins are organized to help penetrate host mucus.
Explanation:
The surface of viruses includes many copies of one type of protein that binds, or adsorbs, specifically to multiple copies of a receptor protein on a host cell.
The surface protein of influenza virus, hemagglutinin, helps the virus attach and enter host cells.
What are surface proteins?The surface protein on the influenza virus is called hemagglutinin (HA) and it plays a critical role in the virus' ability to infect host cells. HA is a glycoprotein that protrudes from the surface of the virus and binds to specific receptors on the surface of host cells, particularly in the respiratory tract.
This allows the virus to enter the host cell and hijack its machinery to replicate and produce more virus particles. The HA protein also enables the virus to evade the immune system by constantly changing its structure through a process called antigenic drift, which prevents recognition by the host's antibodies.
The importance of the HA protein makes it a prime target for the development of vaccines and antiviral drugs against influenza.
