In 2000, Bob Harmon discovered the best-preserved Tyrannosaurus rex skeleton ever found. The fossilized dinosaur was sticking out of the wall of a canyon in Montana. Many scientists were eager to study the fossils.


Dr. Mary Schweitzer got one of the leg bones to analyze. Dr. Schweitzer’s assistant dissolved the bones in acid and discovered that some soft tissue had survived even after 68 million years. The discovery was a shock to the scientific community. No one had ever found such old tissues.


Next, Dr. Schweitzer looked for evidence of proteins in the T. rex tissues. She matched several samples from the fossil to parts of the modern protein collagen. Dr. Schweitzer’s discovery was so revolutionary that very few scientists believed her results. She repeated the experiment several times with great care. Each time she got the same results. In 2017, the scientific community finally accepted that proteins really could survive intact for 68 million years.


Considering the body’s organization from atoms to organ systems, in which level of organization are proteins like collagen? Describe how this level of organization fits into the organization of the whole body.

Answer 1

Answer:

59.889 ithink

Explanation:

Answer 2

The level of organization in the body tells about the structural framework. According to the level of organization, proteins like collagen are categorized as molecules.

What is the level of organization?

The level of organization is the structural formation that makes the whole organism and starts with a basic and smallest unit that is combined at upper levels to form the structures.

The proteins like collagen are considered molecules, as they are made of various elements, joined together by bonds. Collagen is considered the chemical level that makes the cells and further tissues.

Collagen is a structural component that further forms a cell, tissue, and organs and is involved in the transportation of oxygen, and supports bones, skin, and tissues.

Therefore, the proteins like collagen are molecule-level of organization.

Explanation:

The amoeba have identical offspring while all others have genetic variences

The scenarios of reproduction which is most likely to form uniform offspring is an amoeba splits during binary fission into two separate cells. Thus, the correct option is D.

What is Reproduction?

Reproduction is the process of formation of new organisms which are similar to the parent organism or parent cell. Reproduction is the process which generally occurs through different methods in a living cell or an organism.

Reproduction is mainly of two types, which include Asexual and Sexual mode of reproduction. Asexual reproduction is the reproduction where only one organism is involved in the process and it does not need the formation of gametes or the sex cells and sexual reproduction results into the formation of organisms through the fusion of gametes from two different organisms.

An example of asexual reproduction is an amoeba which splits through the binary fission into two separate new daughter cells.

Therefore, the correct option is D.

Particularly important dietary carbohydrates include starch and disaccharides such as lactose and sucrose. None of these molecules can be absorbed for the simple reason that they cannot cross cell membranes unaided and, unlike the situation for monosaccharides, there are no transporters to carry them across

which kind of soil is likely to have the HIGHEST porosity? A) Soil that is a mixture of sand and clay. B) soil that is all clay. C) soil that is a mixture of silt and clay. D) soil that is all sand.

Answers

Explanation:

Sand have the largest particle size so it has the highest porosity.

The answer is Soil that is all sand (D).

Soil that is all sand is likely to have the HIGHEST porosity. Therefore option D is correct.

Porosity refers to the amount of empty space or voids within a soil or rock. It is a measure of how much water or air can be stored in the soil. The type and arrangement of soil particles greatly influence porosity.

Sand particles are relatively large and have larger spaces between them compared to clay or silt particles. This means that sand has a higher porosity because it has more empty spaces or voids that can hold water and air.

The larger particle size allows for better drainage and easier movement of water and air through the soil.

In contrast, clay particles are much smaller and tightly packed together, resulting in smaller spaces between them. This compact arrangement reduces the porosity of clay soils, making it harder for water and air to penetrate and move through the soil.

Soil that is a mixture of sand and clay may have a moderate porosity, as the sand particles contribute to higher porosity while the clay particles reduce it to some extent. Similarly, soil that is a mixture of silt and clay may also have moderate porosity.

Therefore, if we consider the given options, soil that is all sand is likely to have the highest porosity due to the larger particle size and the resulting larger spaces or voids between the sand particles.

What are rotating air currents circulating around a vertical axis inside a supercell?

Answers

Answer:

Supercell thunderstorms are perhaps the most violent of all thunderstorm types, and are capable of producing damaging winds, large hail, and weak-to-violent tornadoes. They are most common during the spring across the central United States when moderate-to-strong atmospheric wind fields, vertical wind shear (change in wind direction and/or speed with height), and instability are present. The degree and vertical distribution of moisture, instability, lift, and wind fields have a profound influence on convective storm type, including supercells, multicells (including squall lines and bow echoes), ordinary/pulse storms, or a combination of storm types. Once thunderstorms form, small/convective-scale interactions also influence storm type and evolution. There are variations of supercells, including "classic," "miniature," "high precipitation (HP)," and "low precipitation (LP)" storms. In general, however, the supercell class of storms is defined by a persistent rotating updraft (i.e., mesocyclone) which promotes storm organization, maintenance, and severity. More information concerning environmental conditions and the structure of classic and HP supercells is given below. WSR-88D Doppler radar imagery showing the evolution of some supercell events across Kentucky and south-central Indiana are available.
