Answer:
The correct answer is option A (the motions of Earth).
Explanation:
The word "Time" may have different meanings, "Time" in a simple term, it is used to measure events, and it is the bedrock that is used to determine seasons. Time is measured in seconds, minutes, hours, days, weeks, months, years. Unlike clocks, and other different devices used to measure time, these devices were not available some centuries ago. So, time was measured in those centuries with the help of the knowledge of the rising and setting of the sun which are caused by the rotation of the Earth. The most standard unit of time used this day are all products of research Astronomers were able to do through studying the motions of the Earth. For instance, when the Earth makes a full rotation around its own axis, that signifies a day, which is a period of about 24hours. considering we have leap years, so it is not complete 24 hours.
What theory’s/ideas challenge natural selection? In other words, what disproves natural selection?
Answer:
Natural selection needs some starting material, and that starting material is heritable variation. For natural selection to act on a feature, there must already be variation (differences among individuals) for that feature. Also, the differences have to be heritable, determined by the organisms' genes.

When a pinecone is open, it disperses its seeds. Based on your experiment, can you tell what weather conditions are needed for pine trees to release their seeds? Explain your answer.
Answer:
If a pine seed finds the right micro-climate, it will eventually sprout and a pine seedling will start to grow. However, pine seeds are usually released in a dormant state, which is most often broken by cold stratification. As a result, a pine seed will not sprout until the following spring when warm weather and some spring moisture are present.

Which of the following can occur because of the exchange of homologous chromosome parts during the process of meiosis?
Answer:
Muttation can occur during the exchange of genetic meterial from homologous chromosomes which may led to cause deseases in some cases.
Explanation:
Homologous chromosomes exchange genetic material during the process of meiosis.
What is Meiosis?Meiosis is a type of cell division in which germ cells present in the sexually-reproducing organisms produces the gametes, such as sperm or egg cells. It involves two rounds of division which results in four cells with only one copy of each chromosome.
These four cells are haploid in nature. Meiosis produces the sex cells or gametes like eggs in females and sperm in males.
Meiosis is divided into nine stages. These are divided between the first time the cell divides (meiosis I) and the second time it divides (meiosis II).
Thus, homologous chromosomes exchange genetic material during the process of meiosis.

Give an example of how Eubacteria can be beneficial. Explain. Please help me.
Answer:
Some bacteria are good for you, including the bacteria in your digestive system, or gut. These bacteria help to break down food and keep you healthy. Other good bacteria can produce oxygen are used to create antibiotics. Bacteria are used in food production to make yogurt and fermented foods.
An example of how Eubacteria can be beneficial is that these bacteria fix nitrogen for soil that can be used by living beings.
What are eubacteria?The bacteria in your gut and digestive tract are among the beneficial bacteria. These microorganisms aid in the digestion of food and promote good health. To make antibiotics, other beneficial microorganisms that can also produce oxygen are employed. Yogurt and other fermented foods are produced using bacteria in the food industry.
Oxygen, carbon, nitrogen, and phosphorus that living things like animals and plants cannot use can be converted by eubacteria into usable forms. In the soil, they fix the nitrogen that is present in the air.
Therefore, Eubacteria can help the environment by fixing nitrogen into the soil so that living things can use it.

What do codons in DNA code for?
Answer:
mRNA and then amino acids
Explanation:
Codons are triplets (3) bases that code for defined amino acid sequences.
DNA is transcribed into mRNA. The mRNA codons are then translated into amino acid chains that form proteins.
Each codon codes for an amino acid, which is brought to the growing polypeptide chain by tRNAs via complementary base pairing.

If your body is capable of making only certain amino acids, how do we get the essential amino acids we need?
Answer:
Essential amino acids cannot be made by the body. As a result, they must come from food. The 9 essential amino acids are: histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine.
Explanation:
Essential amino acids are available to the body through diet.
What are amino acids?Amino acids are the key units in protein formation. They are the building blocks in determining protein structure.
Amino acids are amphoteric molecules which means that they contain dual functional group - amino and carboxylic acid.
There are twenty different amino acids present. Amino acids are classified into four main groups:
Non polar amino acidsPolar but charged amino acidsNegatively charged amino acidsPositively charged amino acidsAmino acids are crucial in the determination of genetic code. They are also important in transcription and translation process.
Amino acids are joined together in large number and form polypetides through peptide bond formation.
Based on the nutritional requirements amino acids are classified into two types:
Essential amino acids - amino acids which cannot be synthesized by the body and thus need supplementation through diet.Non essential amino acids - amino acids which can be synthesized by the body.Therefore, amino acids are important in the biochemistry of proteins and several biochemical processes.
