Answer:
Forms of fossil records can inlude the carcasses of animals and the structure of plants. These records can compare the advancements of creatures over a long period of time.
Explanation:
The further an animal or plant is burried underneath the soil, it is most likely that it lived much longer ago than a layer above it. The theory of evolution suggests that animals are always changing and adapting to their surroundings. For instance, millions of years ago, a dog like mamal existed but over time they grew accustomed to the water, developing fins flippers and eventually developed features similar to what we expect in whales today.
Plants, on the other hand, may have been much larger than the size they are today due to the excess of oxygen present in the atmosphere. Therefore, when they are fossilized scientists can realize that plants have come a long way in the tree of evolution.

Why is it possible for a FPR (formyl-peptide receptor) to detect a formyl peptide in the
absence of a bacterial infection?
Answer:
These receptors were originally identified by their ability to bind N-formyl peptides such as N-formylmethionine produced by the degradation of either bacterial or host cells. Hence formyl peptide receptors are involved in mediating immune cell response to infection.Mark me as brainliest ❤️Which is a property of every homogeneous mixture?

An amoeba is a single-celled organism that feeds on algae, plant cells, and bacteria. When an amoeba feeds, it first makes contact with the food particle. Next, the amoeba starts to surround the particle. Once the particle is completely engulfed, it is surrounded by a layer of the amoeba's membrane, forming a vesicle. The pH in the vesicle is then lowered and the contents are degraded.
What type of transport is involved in this process?
A.
endocytosis
B.
diffusion
C.
passive transport
D.
exocytosis
Answer:
A. endocytosis
Explanation:
Endocytosis is the type of transport that is involved in this process because it engulf the food material. Amoeba engulfs food particles with the help of its pseudopodia which are the projections of cell membranes. A food vacuole is formed around the food particle. This process of engulfing a matter by the projections of the cell membrane to form a vacuole is called endocytosis.

During the respiration of an organism
A, 1 molecule of glucose produces 2
ATP molecules whereas in the
respiration of another organism B, 1
molecule of glucose produces 38 ATP
molecules. Which of the organisms, A
or B has anaerobic mode of
respiration? Explain with reason.
Answer:
The correct answer is - organism A is anaerobic.
Explanation:
Organism A can convert glucose into alcohol, as it undergoes anaerobic respiration, however, there is an incomplete breakdown of glucose. In this process, there are only two molecules of pyruvate formed, and the rest convert to lactic acid or ethanol.
The energy is only enough to release two ATPs. In the aerobic process, there is a complete breakdown of glucose in CO2 and H2O with 38 ATPs.
The correct answer is - organism A is anaerobic.
7. Give two examples of biochemical reactions and explain how an organism uses ATP within the reactions.
Answer:
Because of its energy supply, ATP is necessary for all biological reactions.
ATP is employed both in salt and potassium pumping operations and in the cellular breathing mechanism.
Explanation:
The breakdown of glucose, which frees the cell's energy for life functions, is an example of a catabolic response. Endothermic reactions are called anabolic processes in organisms. The connection between amino acids and a protein is an example of an anabolic response.
If a cell needs energy, this link breaks into adenosine diphosphate (ADP) and a free molecule of phosphate... With an excess power of the cell, this energy is stored by creating ATP from ADP and phosphate. For any muscular contraction, ATP is needed for metabolic reactions.
-To break down one glucose into pyruvate molecules in Glycolysis 2 ATP molecules 4 ATP molecules are produced for a net addition of 2 ATP molecules.
-An inorganic carbon is converted into sugar by ATP in photosynthesis.
A triplet of bases in a template strand of DNA is GAT. What would be the corresponding codon for mRNA?
СТА
CUA
CTU
CUA (This one is wrong)
I don't know why there are two CUAs, but if someone could please help. This is confusing for me. Please explain & no false answers. Thanks much in advance!
Answer:
CUA
Explanation:
Chances are your teacher accidentally put the same option twice and marked one of em incorrect. You infact selected the correct answer because CUA is correct.
DNA has 4 bases: ATGC (Apples on Trees = A - T, & Cows eat Grass = C-G)
RNA has 4 bases: AUGC (RNA lacks the base T so A binds with U instead).
So for template strand GAT, the mRNA made from this codon has complimentary pairing based on RNA so G binds with C, A binds with U, and T binds with A.
A triplet of bases in a template strand of DNA is GAT, the corresponding codon for mRNA - CTU
DNA is a two-stranded molecule. Each strand is a polynucleotide composed of A (adenosine), T (thymidine), C (cytidine), and G (guanosine) in a sequence.
Adenine always bonds with thymine, and guanine only bonds with cytosine. In RNA however, uracil is substituted for thymine instead. So, in transcription, adenine turns into thymine, and guanine turns into cytosine, and vice-versa.
Thus, A triplet of bases in a template strand of DNA is GAT, the corresponding codon for mRNA - CTU

A food chain consists of several organisms. Suppose one of the organisms in the chain disappears. What effect can this have on the other organisms in the food chain?
Answer:
All organisms in that food chain would starve until they die unless they could possibly move to a different habitat.
Explanation:
And because of all those organisms not being able to properly feed due to an organism missing in the food chain of that habitat, the population of those animals would decrease as well.

If isolated from a eukaryotic cell, mitochondria can no longer survive and reproduce on their
own.
If isolated from a plant cell, a chloroplast can survive and reproduce on its own.
Answer:
C. If isolated from a eukaryotic cell, mitochondria can no longer survive and reproduce on their own.
Explanation:
The endosymbiotic theory proposes that early eukaryotic cells evolved from endosymbiotic interactions among prokaryotic cells. This theory states that mitochondria and chloroplasts were once primitive bacterial cells that were ingested by large anaerobic prokaryotic cells, and then these cells benefited from living and working together. The most important lines of evidence that support this theory are that mitochondria and chloroplasts contain their own genetic material (circular DNA) and their own protein biosynthesis machinery (ribosomes).

Different types, or isotopes, of oxygen exist in the ocean and are incorporated into the skeletal fragments of animals. What can the ratio of preserved isotopes tell us about climate?
Answer:
The correct answer is - Certain ratios of oxygen reflect either warmer or cooler ocean temperatures.
Explanation:
Ocean have different isotypes or types of oxygen throughout the ocean and also incorporated in the shells of the marine animals of the particular region and time.
We can found out the climate and more particularly the temperature of the ocean as The more 18^O found in the shell or sediment of the animal, the colder the climate and vice versa, however, it is opposite in relation to that of glacier ice.

beak distribution
Answer:
The answer is "supported and when fruit was removed"
Explanation:
It dated the idea from this laboratory because the distribution of avian beaks differed. If any kind of food available keeps shifting, the frequency of the beak types changes as beaks with beaks is far more suitable for food available. The data in this laboratory confirmed the theory, so because the fruit was removed by birds.
