Answer:
Expertise in 1 area
Explanation:
If you had a general knowledge of literally everything, that is great for mastering school. But, you are not going to school your whole life. You need college, work, and so on. When in college, it isn't like school, you can only choose 1 subject. Thus, it is good to expertise in 1 area.
I hope this helps you :)

Describe how radiocarbon dating method is used to find the absolute age of a fossil?
Answers
Answer:
Radiocarbon dating involves finding the age of an ancient fossil by measuring its carbon-14 content. Carbon-14 (radiocarbon), is a naturally occurring radioactive isotope that forms when cosmic rays in the upper atmosphere strike nitrogen molecules, which then oxidize to become carbon dioxide.
why does a deletion mutation usually cause more defects during protein synthesis than a point mutation?
Answers
Answer:
Deletion mutations can affect the entire base sequence.
Explanation:
Answer:
Deletion mutation may cause a shift of base sequence, causing the reading frames for base sequence to change during translation. This may affect the type of amino acid it the original base sequence codes for, resulting in a change in amino acid sequence in the polypeptide translated. Therefore, affecting the whole protein itself. There may be wrong amino acids that prevents vital bonds like disulfide bridges to form, resulting in a huge change in 3 dimensional conformation of the protein. A point mutation may result in a gene sequence being edited. However, only the target sequence is being mutated. The rest of the gene sequences are left untouched. Therefore, the impact is localised. This ensures that even though a few wrong amino acids may be in the polyleptide, most of the bonds that are crucial for the correct 3 dimensional conformation is still present, therefore, lesser defects will be resulted due to point mutation as compared to deletion mutation.

Answers
Answer:
data
Explanation:
All the facts and observations gathered in an experiment are called data. Therefore, option B is correct.
What is an experiment?An experiment is a technique used to confirm or deny a hypothesis, as well as assess the likelihood or effectiveness of something that has never been tried before. Experiments show what happens when a specific factor is modified, which sheds light on cause-and-effect relationships.
The three primary categories of scientific experiments are quasi-experimental, observational, and experimental (non-experimental). The most rigorous type of scientific investigation is experimental, often known as randomized control. The most control is present, as the name would imply.
Data are the facts and the observations gathered in an experiment. Therefore, option B is correct.

Explanation:
If carbon dioxide was removed from a plant's environment, what would you expect to
happen to the plant's production of sugars?
O fewer sugars will be produced
more sugars will be produced
O carbon dioxide does not affect the production of sugars in plants
o the same number of sugars will be produced but without the carbon dioxide
Answers
Answer: Fewer sugars will be made because plants use carbon dioxide in photosynthesis.
Hope this helps
Plants are autotrophs, which prepare their food in the presence of sunlight, water, and carbon dioxide to yield sugar and oxygen.
The carbon dioxide is removed from the plant's environment, then less sugar will be produced.
Photosynthesis is a metabolic process in which plants prepare food in the presence of sunlight, carbon dioxide, and water. The products of photosynthesis are oxygen and sugar molecules.
The carbon dioxide if removed or reduced from the plant's environment, then the plants will be unable to perform photosynthesis properly, and in the limited resources, the products formed will be reduced.
Thus, the correct answer is Option A.

Give two uses of energy transferred by respiration in eukaryotes
Answers
Answer:
Most aerobic respiration takes place inside mitochondria. Some of the energy released in respiration is used to make larger molecules from smaller ones, to enable muscles to contract and to keep temperature steady. Some of the energy released in respiration in plants is used to make amino acids and proteins.
Explanation:google said it and i had this question in my science class and got it right
The uses of energy are - energy for metabolic reaction and growth and development of cells.
Cellular respiration provides energy with the series of complex chemical reaction cycles that is used for:
Working your muscles - for movement and physical activities energy is required.Growth and repair of cells - dividing cells, repairing them and development of the cells also require energy.Building larger molecules from smaller ones for instance proteins from amino acids.Allowing chemical reactions to take place.Absorbing molecules in active transport.Thus, The uses of energy are - energy for metabolic reaction and growth and development of cells.

Ca2+ is important for cellular signalling, for once it enters the cytosol of the cytoplasm it exerts allosteric regulatory effects on many enzymes and proteins. Ca2+ can act in signal transduction resulting from activation of ion channels or as a second messenger caused by indirect signal transduction pathways such as G protein-coupled receptors.
