Answer:
Fossils provide solid evidence that organisms from the past are not the same as those found today; fossils show a progression of evolution. Fossils, along with the comparative anatomy of present-day organisms, constitute the morphological, or anatomical, record. By comparing the anatomies of both modern and extinct species, paleontologists can infer the lineages of those species. This approach is most successful for organisms that had hard body parts, such as shells, bones or teeth. The resulting fossil record tells the story of the past and shows the evolution of form over millions of years.

Ultra-high-temperature sterilization effectively reduces microbes that cause spoilage. removes only mesophilic microbes. reduces microbes that cause disease. removes all microbes that cause diseases or spoilage. reduces microbes that cause disease or spoilage.
Answer:
kills all microbes that cause disease or spoilage.
Explanation:
There are different methods of sterilization, such as ultraviolet radiation, autoclave mechanisms, etc.
The sterilization mechanisms eliminate the microorganisms completely, thus generating sterile surfaces.
These mechanisms are used with surgical instruments, the operating room environment.
The autoclave method is the most widely used today due to its economical price, its ease of use and its practicality.
Sterilization methods must be strictly controlled with pilot or test microbiological cultures to be able to corroborate that these mechanisms function correctly, since otherwise they could trigger strong pathologies due to cross contamination.

Explain how scientific knowledge develops through making observations about the natural world.
Answer:
Scientific knowledge develops through making observations about the natural world. An observation may generate a scientific question, which may lead to a hypothesis. The hypothesis can be tested through experimentation. The results of experimentation lead to changes in scientific knowledge.

Which statement is always true when describing sex-linked inheritance? It results in a dominant trait. The alleles are found on the X or Y chromosome. The resulting trait is influenced by multiple alleles. It is affected by alleles on at least three different chromosomes.
Answer:
the second one
Explanation:
there are only 2 sex linked chromosomes and that is X and Y
The true statement when describing sex-linked inheritance is ; ( B ) The alleles are found on the X and Y chromosome
The alleles responsible for reproductive inheritance from parents to offspring is contained in the X and Y chromosome of the reproductive gametes.
The female gametes contains double X chromosomes while the male reproductive gametes contains one X and one Y chromosomes. The alleles that are responsible for inheritance ( i.e. the sex of the offspring ) are contained in this chromosomes.
Hence we can conclude that The true statement when describing sex-linked inheritance is the alleles are found on the X and Y chromosome.

13. List 4 safety symbols that would be seen if you are working with a material that is biohazard, such as bacteria.
Answer:
1. Skull and crossbones
2. A triangle (commonly painted colour red or yellow) with an exclamation sign inside.
3. biohazard symbol
4. A radiation sign in the form of a triangle, having other little image descriptions inside.
Explanation:
Note that a biohazard material refers to dangerous substances of biological (living) nature that can pose a threat to humans. Thus, safety symbols try as much as to draw attention to the descriptions used.
For example, skull and crossbones and biohazard symbols are used to indicate that a material that is biohazard, such as bacteria could result in the death of a person.

What has a greater influence on protein levels?
(1 point)
Protein degradation has a greater influence because outside factors like antibiotics can
cause it, and it is difficult to recover from.
O
Protein degradation has a greater influence because they are denatured faster than the cell
can produce them.
mRNA destroyer concentration has a greater influence because it is destroying mRNA before
proteins can even be produced.
mRNA destroyer concentration has a greater influence because mRNA is destroyed right
after the proteins are produced.
Answer:
mRNA destroyer concentration has a greater influence because it is destroying mRNA before proteins can even be produced.
Explanation:
Proteins are synthesized from mRNA through the process of translation. mRNAs are first synthesized from a coding DNA template through the process of transcription. Hence, if mRNAs are destroyed, it means proteins will not be synthesized at all.
Protein not being synthesized at all means that mRNA destroyer concentration has a greater influence on protein levels than protein degradation. With protein degradation, not all the protein is degraded at once and some quantity of the protein can still be found, but with mRNA destroyer concentration, no protein can be found at all because it was not synthesized in the first place.

Muscle cell are richer in lysosomes , as they require lot of energy. correct and rewrite the following statement.
Answer:
See below
Explanation:
The correct statement is:
=> Muscle cells are richer in mitochondria, as they required lots of energy.
Mitochondrion acts as power house of the cell providing the cell with the required energy.
Muscle cells are richer in Mitochondria, as they require a lot of energy.
[tex] \large{ \underline{ \boxed{ \pink{ \rm{Explanation}}}}}[/tex]
Especially in Skeletal muscles, Mitochondria and glycogen granules are found in abundance. Our limbs that includes our arms and legs shows movement which needs energy. The food is oxidized and energy is released.
More to know:-Mitochondria is popularly known as Power house of the cell or ATP generation site.It is a double-membranous structure with outer membrane smooth and inner membrane surrounds the matrix.The inner membrane have cristae which increase surface area.The cristae bear Oxysomes or F0-F1 particles.Mitocondria is semi-autonomous, it have it's own DNA and ribosomes.━━━━━━━━━━━━━━━━━━━━

How are the proteins inside your body affected by the presence of water and other molecules?
Answer:
Our body is constitute of several essential molecules such as proteins, fat, carbohydrate, water, and other molecules.
Each molecule has some of the impact of other molecules in the body. Impact of water and other molecules on proteins inside the body are as follows:
Proteins have ligand-binding site and water provide stability to the ligand-binding site of proteins through its hydrogen bonds.Conformational flexibility and transitions of proteins are due to the presence of water molecules in it.Disbalance in the pH of body due to changing concentration of sodium-potassium ions can denature the protein. Enzymes present in the body can control the rate of formation of proteins in the body.
