Answer:
Pasteurization
Explanation:
Food products such as milk, wine and beverages may be subjected or placed on a heat treatment process with the aim of reducing active microorganisms present in them. This will improve the quality of food materials and also prolong its life span. This heat treatment process help destroy pathogenic microorganisms and those which are responsible for food spoilage. Once this food spoilage microorganisms are destroyed, the good products will have enhanced or prolonged life span of the food product and also reduces their risk of causing disease.
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.

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

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.
Select all that apply Select all true statements about the Glomeromycota. Multiple select question. They are plant pathogens and parasites. They do not undergo sexual reproduction. They lack nuclei. They form arbuscular mycorrhizae.
Answer:
They do not undergo sexual reproduction.
They form arbuscular mycorrhizae.
Explanation:
Glomeromycota form arbuscular mycorrhizae and they do not undergo sexual reproduction.
Glomeromycota is one of the divisions of fungi that can be found in soils where they form symbioses(association where both glomeromycota and the plant benefits) with the roots of the plants. They can also be found in wetlands. An example of glomeromycota is Acaulospora.
They are also called mycorrhiza. They reproduce through asexual reproduction.

hypothesis because there was a difference in bird
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. These results of this laboratory confirm this idea because the dispersion of pigeons when food was taken was varied.

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).

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.

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.

66. A 64-year-old woman, who has always been proud of her suntanned, healthy look, is referred to a dermatologist with a blue-violet, painless, 1.5-cm lump in the skin of her left shoulder. The lump is firm and cannot be moved, and has grown very rapidly over the past few weeks. The mass is removed surgically and the pathologist diagnoses it as a Merkel cell carcinoma. If the UV radiation to which her skin was exposed affected the Merkel cells, what other cell type sharing the same specific epidermal layer might also be affected
Answer:
Basal stem cells for keratinocytes
Explanation:
Keratinocytes are epidermal cells located in the outermost layer of the skin (i.e., the epidermis). Moreover, the cells located in the basal layer of the skin are known as basal keratinocytes or basal cells. These basal cells are proliferative cells that undergo differentiation in order to form suprabasal epidermal layers. Merkel cells are neuroendocrine cells that are located in the basal layer of the skin (scattered among basal keratinocytes), which are attached to surrounding keratinocytes by intercellular junctions called desmosomes.

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 ❤️
