D. phospholipids
Chromosomes determine all inherited traits because they are made up of DNA.
What are the functions of chromosomes?Chromosomes allow DNA to be accurately copied during these cell divisions. So one more time. Chromosomes are found in the nuclei of our cells and allow DNA to be accurately copied during cell division. This ensures that our inner workings proceed smoothly and efficiently.
The main function of chromosomes is to carry the DNA and transfer the genetic information from parents to offspring. Chromosomes play an important role during cell division. They protect the DNA from getting tangled and damaged.
Chromosome are the thread-like structures intermingled with each other in the nucleus. They carry genes that help in the transfer of characters from the parents to the offspring and thus play an important role in the inheritance of characters.

Which statement best explains how the mass of an atom is organized?
Most of the mass is contained in the nucleus.
The mass is spread evenly throughout the whole atom.
The mass is spread evenly throughout the electron cloud.
Most of the mass is contained in the electron cloud.
Answer: A
Explanation: most of the mass contained in the nucleus.
Most of the mass of an atom is contained in the nucleus. So the correct option is A.
What is atomic mass?The amount of matter that is contained in an atom is defined as the atomic mass of an atom. In mathematical terms, atomic mass is 1/12th of the mass of a carbon-12 atom. This is assigned an atomic mass of 12 units.
The unit for measuring atomic mass is called Dalton after the English scientist John Dalton.
Atomic mass is expressed as the sum of the mass of protons and neutrons. Protons are positively charged particles and neutrons are particles with no charge.
Atomic mass is expressed as the mass of protons and neutrons because protons and neutrons are present in the nucleus. Thus, it is said that most of the mass of the atom is concentrated in the nucleus.
The mass of electrons is comparatively less than the mass of protons and neutrons combined. Also, electrons are present in the atomic shells of the atom.
Therefore the correct option is A.

Here is your answer
uses of carbohydrates
Production of pulp from wood cellulose, applications of starch for paper making as well as uses of glucose and saccharose for fermentation are the most important chemical and technical uses of carbohydrates. Carbohydrates used as fermentation feedstock are essential for the chemical industry.
The use of proteins from renewable raw materials contributes to the creation of a biobased, sustainable economy. Proteins are used in many industries mainly in the form of enzymes. Consider the importance of enzymatic catalysis in the food, textile and detergent industries.
Imagine you have a five-step food chain. If 100 percent of the energy is available at the first trophic level, what percentage of energy is available at the highest trophic level?
Answer:
0.1% will be available at the highest trophic level
0.001 % of energy is available at the highest trophic level because about only ten precent of energy is carried from each step in the food chain.
What is food chain ?In the wild, the food chain describes who eats whom. Everything that is alive, from microscopic algae to enormous blue whales, depends on food to thrive. Each food web represents a possible route for nutrients and energy to travel through the ecosystem.
As an illustration, grass makes its own sustenance from sunshine. A bunny consumes some grass. Eaten by a fox, the rabbit. When a fox dies, microbes decompose its remains and return it to the soil, where it feeds grass-like plants.
There is less biomass at the top of the food chain since there is less energy there than at the bottom, therefore the first 100 percent, 10 percent, 1 percent , 0.1 percent, 0.01 percent, and eventually 0.001 percent of energy are carried from each level in the food chain.
Therefore, only 0.001% of the energy is available at the first trophic level.

2) If the last base in the underlined sequence was changed by mutation to a “C”, how would the protein be changed?

If the 4th base in the sequence was deleted by radiation (mutation), how would the sequence be changed.
What is Mutation?A mutation is a change to an organism's DNA sequence. Errors in DNA replication during cell division, exposure to mutagens, or viral infection can all cause mutations.
Somatic mutations (which happen in body cells) cannot be passed on to offspring, whereas germline mutations (which happen in eggs and sperm) can.
Our cells are constantly undergoing mutations, yet very few of these have any negative effects on our health. A mutation is never so advantageous in real life that it makes someone a superhero or does anything strange like give them wings.
Therefore, If the 4th base in the sequence was deleted by radiation (mutation), how would the sequence be changed.
