Answer:
Structure of large intestine: Large intestine is the part of digestive system which comes in the end. It consist of four parts. Large intestine length is 150 cm and width is 5 cm.
Function of large intestine: It performs two main functions.
1) Large intestine helps in the absorption of water and nutrients from the food which cannot be digested in the stomach.
2) It removes the waste material from the body in the form of feces.
TCTCG and AGAGC are the perfect pair.
Option A
<h3><u>Explanation:</u></h3>
DNA is the genetic molecule of a living cell. The DNA stores genetic information of the species inside itself by means of particular pattern or sequence of nitrogen bases called as gene. The gene is comprised of the particular sequence of nitrogenous bases which are four in number - adenine, guanine, thymine and cytosine.
The nitrogen bases are present in both the strands of DNA and they have complementary relationship between them. The adenine forms hydrogen bonds with thymine and guanine pairs with cytosine.
Here the sequence of one strand is given as TCTCG. So according to the complementary pairing process, the opposite strand must have the sequence of AGAGC to maintain the structure.
Answer:
pores
Explanation:
The nucleus consists of "nuclear pores" on its outer membrane. Each of these are surrounded by <em>nuclear pore complex.</em> It allows the pore to <u>regulate the movement of molecules between the nucleus and the cytoplasm.</u> It allows small particles to pass through such as ribosomal proteins. It prevents most large particles<em> (except for histone)</em> from passing through; thus, <u>it is selective in nature</u>. This function of the pores clearly shows that <em>it allows communication to occur between the nucleus interior and the cytoplasm.</em>
This because ice is less dense than water of particular temperature range. Water reaches its maximum density at 4 degrees. Ice is important especially for aquatic life in the polar regions. Polar bears give birth and hunt on sea ice and they need it to travel from one region to another. The ice edge in coastal areas is an important feeding ground for the walrus that uses the ice as diving platforms to feed on clams on the sea floor. Ice algae grow at the porous bottom of sea ice and form the base of the unique marine food web connected to sea ice
