Which of the following is TRUE about the fossil record? Group of answer choices It is sadly incomplete and lacking in all transitional forms. It gives useful information about environments and the ways past organisms lived. Only animals with hard skeletons are preserved. It is best in deep forests where dead organisms have not been disturbed.
Answer:
It gives useful information about environments and the ways past organisms lived
Explanation:
A fossil is basically any preserved remains or trace of any organism that once lived in the past. Bones, shells and exoskeletons are examples of fossils that can be studied through Paleontology.
From fossil studies, we can tell how long these lives existed on earth and how varying plants and animals are related to one another. We can often find out how and the places they lived and their environments as well.

Plz mark brainliest:)
Two products of the Krebs cycle are NADH and FADH2.
What is the Kreb's Cycle?The Krebs cycle is a form of chemical reaction that is meant to convert the energy stored in the body in the form of acetyl CoA to other constituents.
Some products of the Krebs Cycle also known as the Citric acid cycle are Nicotinamide adenine dinucleotide and Flavin adenine dinucleotide. The energy released is from carbohydrates and fat.

What part of the cell determines the type and order of the amino acids that make up a protein?
Answer:
The gene, or sequence of DNA, ultimately determines the unique sequence of amino acids in each peptide chain. A change in nucleotide sequence of the gene's coding region may lead to a different amino acid being added to the growing polypeptide chain, causing a change in protein structure and therefore function.
After an organism dies, it stops taking in radioactive carbon-14 from the environment. If the carbon-14:carbon-12 ratio ( / ) in a piece of petrified wood is one sixteenth of the ratio in living matter, how old is the rock
Answer:
Age of rock= 22920 years
Explanation:
Carbon-12 isotope is a stable isotope whereas carbon-14 isotope undergoes radioactive decay. The half-life of carbon-14 isotope = 5730 years
Since the ratio of carbon-14 to carbon-12 = 1/16 : 1; number of times carbon-14 isotope decayed n
(1/2)ⁿ = 1/16
(1/2)ⁿ = (1/2)⁴
n = 4 times
time(age) for decay = n * half-life
Therefore, age of fossil = 4 * 5730 years
Age of rock = 22920 years

What characteristic properly describes glycogen?
Answer: What are the characteristics of glycogen?
It has a structure similar to amylopectin (a component of starch), but is more extensively branched and compact than starch. Both are white powders in their dry state. Glycogen is found in the form of granules in the cytosol/cytoplasm in many cell types, and plays an important role in the glucose cycle.

Answer:
Reference maps show the location of geographic boundaries, physical features of Earth, or cultural features such as places, cities, and roads.
Explanation:
Answer:
It is a representation of a place in which the relationship toward time and space is perceived. The purpose of maps are to provide visual representations of the physical features of the Earth to teach and guide. Maps are used to navigate from one place to another, to know the location of an area or region, and to measure distances from certain locations.

Which products do not have scientific studies supporting their claims to be beneficial when used?
A. Cofactors and coenzymes to support enzyme function
B. Lactase enzymes used in milk sugar digestion
C. Enzyme that aids in the digestion of oligosaccharides
D. Enzymes to promote immune system function
Cofactors do not bind to the enzyme, whereas coenzymes frequently bind loosely to an enzyme's active site and help recruit substrates. Coenzymes are organic compounds. Thus, option A is correct.
What is the importance of Cofactors and coenzymes?Cofactors and coenzymes are substances that support the proper operation of an enzyme or protein.
Cofactors are organic and inorganic substances that help enzymes catalyze processes. The majority of coenzymes are vitamin derivatives that are soluble in water by phosphorylation.
Typically, cofactors are used to provide chemical groups or qualities that are absent from other chemical groups.
A cofactor like ATP, for instance, has a special capacity for transferring energy to power chemical reactions like the activity of enzymes and transport proteins.
Therefore, Cofactors and coenzymes to support enzyme function.

It then has an unwanted effect on the dependent variable and is termed a confounding variable .The researcher can no longer draw conclusions regarding the causal
A biologist is trying to understand the relationship between water and plant growth. She hypothesizes that if she were to give a plant too much water, it would not grow as much. She designs an experiment to test her hypothesis. She plants 2 same-sized plants in the same amount of soil and places them in the same room. She gives Plant A a normal 200 mL of water daily, and gives Plant B a larger 500 mL of water daily. After 1 week, she notices that Plant A grew more than Plant B.
Answer:
The plant A grew better because a water needs normal water but if we put more water to the plants then it will die
