Answer:
That's how much information is stored in the DNA inside every human cell: the entire human genome. If you sort through the three billion letters that make up the human genome, you find some surprising things. Only about 1% of the three billion letters directly codes for proteins.
Explanation:
The DNA code contains 64 combinations that are named as codons. These codons are coding for the 20 amino acids, which the cell then puts together to form long amino acid chains, known as proteins.
What is DNA?DNA stands for deoxyribonucleic acid. It may be defined as a molecule that is present inside cells that contains the genetic information responsible for the development and function of an organism. DNA molecules allow this information to be passed from one generation to the next.
There are 3.2 billion DNA codes that are used by life on Earth. Of the three billion genetic building blocks that make us living things, only a handful are uniquely ours. In fact, despite our differences on the outside, humans are 99.9% genetically similar to one another.
Our genetic manual holds the instructions for the proteins that make up and power our bodies. But less than 2 percent of our DNA actually codes for them. The rest 98.5 percent of DNA sequences is so-called “junk DNA” that scientists long thought useless.

The combination of absolute and relative dating allows scientists to determine the ages of rocks and fossils. Absolute dating provides evidence that helps us estimate the ages of Earth. How can scientists find the absolute age of igneous rocks?
Answer:
By radiometric dating
Explanation:
The relative age of a rock sample is determined by comparing a (or the fossils it contains) to other layers. Relative age of a rock sample can be determined by looking at the position of various rock layers.
Absolute age of a rock sample is the numerical. Absolute age can be determined by using radiometric dating.
According to Oxford dictionary, radiometric dating is "a method of dating geological specimens by determining the relative proportions of particular radioactive isotopes present in a sample."
A scientist is using a species of green algae to study electron transport chain in photosynthesis. He uses a laser to inactivate all of chlorophyll A in the algae, but leaves chlorophyll B intact (case 1). In a separate experiment, the scientist applies a chemical to the algae that inhibits PS I but does not affect PS II (case 2).
Answer:
The scientist done wrong by inactivating chlorophyll A and PS I.
Explanation:
The scientist done wrong by inactivate chlorophyll A and PS I. If he wants to study electron transport chain in photosynthesis, he needs chlorophyll A and PS I for that because the central role of chlorophyll A is to donate electron in the electron transport chain while on the other hand, the primary function of the photosystem I is the NADPH synthesis, where it receives the electrons for PS II.

what is the movement of molecules across a barrier such as the semi-permeable cell membrane called
Answer:
DIFFUSION
Explanation:
Water, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion (or a type of diffusion known as osmosis ). Diffusion is one principle method of movement of substances within cells, as well as the method for essential small molecules to cross the cell membrane.

The result of photosynthesis as glucose and oxygen
A reactants
B products
C gas exchange
D chlorophyll
The result of photosynthesis as glucose and oxygen is basically products. The correct option is B.
What is photosynthesis?Photosynthesis is a process that plants and other organisms use to convert light energy into chemical energy that can then be released to fuel the organism's activities via cellular respiration.
Photosynthesis is important because it is the process by which plants convert carbon dioxide into oxygen using sunlight.
Animals require oxygen to survive, and plants serve as nature's air filter, filtering out harmful carbon dioxide.
Plants absorb carbon dioxide (CO2) and water (H2O) from the air and soil during photosynthesis.
Water is metabolized within the plant tissues, which means it ends up losing electrons, whereas carbon dioxide is reduced, which means it gains electrons. This converts water to oxygen and carbon dioxide to glucose.
Thus, the correct option is B.

Answer: Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water

This a question that you need to apply knowledge of both the digestive system AND biochemistry. You eat
salad with chopped cucumbers, tomato, onion, and Feta cheese with olive oil. Describe the path through the
digestive system of this meal describing how EACH BIOMOLECULE of the meal is digested and absorbed. Discuss all of the organs and enzymes involved.
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.
Mouth
1.Starch----(salivary amylase)--->maltose+dextrose

Small intestine(Jejunum and ileon)

8.sacrose---(sacrase)--->glucose+fructose
9.lactose---(lactase)--->glucose+galactose

Knowing what you know about photosynthesis, explain how the process may reduce
global warming (caused by too much carbon dioxide in the atmosphere).
Through the pores called stomata in their leaves, plants take in carbon dioxide from the atmosphere that they use for photosynthesis. ... But when carbon dioxide levels increase, plants' stomata shrink, releasing less water into the air and reducing the cooling effect.
