Answer:

Explanation:

Reproduction is when a living thing mates and is capable of making another living thing. That means it's the process of NEW living things, because it's being created. Hope that helps:)

All modern classification systems have their roots in the Linnaean classification system. The Linnaean system is based on similarities in obvious physical traits. It consists of a hierarchy of taxa, from the kingdom to the species. Each species is given a unique two-word Latin name.

A strong covalent bond between adjacent nucleotides is: a) a van der Waals bond. b) an ionic bond. c) a phosphate bond. d) a hyd

zhuklara [117]

Answer:

The correct answer will be option-E

Explanation:

The structure of DNA revealed by Watson and Crick showed that Two strands of DNA are present in the intertwined state forming helix representing DNA as a double helix.

Each strand of DNA is made up of the monomer unit of DNA called nucleotide where each nucleotide binds to another nucleotide through weak covalent bond called phosphodiester bond.

The phosphodiester bond is formed between the 3’-OH group of one nucleotide to 5’ phosphate group of another nucleotide. In this way, the phosphate-sugar molecule forms the backbone of the DNA molecule.

Thus, option-E is the correct answer

Answer:

1. cerebellum

2. brainstem

3. cerebrum

4. cerebrum

5. brainstem

6. cerebrum

7. cerebellum

Explanation:

The cerebellum is a region of the brain located behind the top part of the brainstem, which coordinates voluntary movements (e.g., posture, balance, coordination, speech). The cerebellum is well known to regulate the balance of the body. The brainstem is a type of automatic control center that connects the cerebrum with the spinal cord. The pons represents a group of nerves that serve as connection between the cerebrum and cerebellum. The pons are located in the brainstem (between the midbrain and the medulla oblongata). The cerebrum is the largest part of the brain and can be divided into right and left hemispheres. These hemispheres communicate with each other by the corpus callosum.

Drawing a cartoon in pencil, then going back over it later with an ink pen is most similar to which biological process?

Montano1993 [528]

Given that the main reason for which an artist will retrace a drawing in pen is to correct errors and achieve a final draft, we can compare this to the biological process of DNA proofreading.

DNA proofreading is a biological process that takes place during the biosynthesis of DNA. During this time, a chain of DNA is read and a complementary chain is creating, effectively duplicating the genetic code.

During this process, DNA proofreading takes place. This is described as a process in which the DNA polymerase retraces the genetic code, detecting and fixing any errors in the synthesis before the strand is closed once again.

The fact is that both processes, despite taking place in astronomically different situations, share a final goal which is to prepare the "product" for the "final draft". This allows us to draw valid comparisons between the retracing of a cartoon and the proofreading of DNA by the DNA polymerase enzyme.

The main biomolecules present in the meal are carbohydrates but there are also proteins and lipids.

First of all starch will be hydrolysed in the mouth.Saliva contains an enzyme called amylase that turns starch into dextroses and maltose.

In the stomach the HCl will activate the pepsinogen and it will become pepsin that will hydrolise proteins to albumoses and peptones.

Also in the stomach an enzyme called gastric lypase is present which turns lipids into glycerol and fatty acids.

In the duodenum:The pancreas releases pancreatic amylase which turns starch into maltose. It releases pancreatic lypase which turns lipids into fatty acids and glycerol. It releases proteolytic enzymes(trypsin, chemotrypsin, carboxypetidase, elastase, collagenase) which turn proteins, albumoses and peptones into oligopeptides(3-4 aminoacids) and aminoacids.

In the rest of the small intestines enzymes secreted by the cells that line the small intestine work. Oligopeptidases turn oligopeptides into aminoacids. Maltase turns maltose into 2 molecules of glucose. Sucrase turns sacrose into 1 molecule of glucose and one of fructose. Lactase turns lactose into 1 molecule of glucose and 1 of galactose. The intestinal lypase turns lipids into glycerol and fatty acids.
