What are things we can learn from examining hair? Three parts of hair?

Answers

Answer: The hair is an outgrowth or appendage that grows from a hair follicle.

Explanation:

The three parts of the hair are cuticle, cortex, and medulla. The cuticle is the hard part made up of scales with keratin protein, cortex is the inner pigmented part, and the medulla is the innermost part of the hair.

During hair examination the type of cuticular scales helps in determining the organism to which it belongs, diameter of the medulla also helps in determining the organism, the DNA analysis of the hair can link to its origin, the detection of heavy metal poisoning like lead, arsenic, and others. Drug abuse details can also be determined by the hair analysis.

Answers

I believe the answer is A!!!!!

Agricultural technology has evolved over time, with significant leaps during the agricultural and green revolutions.

Agricultural revolution

Agriculture has been one of the sustainers (along with hunting) of early men and as such, has seen gradual development with time. Man has always been looking for better ways to do things in order to achieve outcomes.

With the era of the agricultural revolution, there was a huge transition of humans from the primitive lifestyle of hunting and fruit gatherings to that of agricultural settlements. Better ways to carry out crop production started receiving huge attention. from there, hand-made agricultural equipment started surfacing.

The green revolution has agriculture receiving utmost attention in terms of technological innovations. Farm machinery, agrochemicals, etc, started coming up with the result being a massive increase in crop production and general outputs.

Explain the difference between how light falls on the Earth near the Equator or the Poles

Answers

Answer:

Explanation:

The normal amount of solar radiation reduces from the Equator to the poles. This is because the low latitudes (near the Equator deliver relatively large amounts of radiation all year, and at high latitudes (near the poles), the more slanting angle of the Sun’s rays together with long periods of darkness in the winter, result in a low amount of received radiation.

23. In both plant and animal cells, the cell
membrane
(1) produces enzymes
(2) controls reproduction
(3) is composed of sugars

(4) regulates diffusion

Answers

Answer:

the answer is option 1

The Cell membrane regulates diffusion, in plants and animal cells.

What is a Cell Membrane?Every biological cell has a thin membrane that separates it from the rest of the environment this membrane is known as a cell membrane.Cell membranes is made of lipids and proteins.The cell membrane's chemical nature makes it extremely flexible, making it a perfect border for quickly growing and dividing cells.Cell membrane is a semi-permeable membrane.

Cell membrane does not produce enzymes.

Hence, the option (1) is incorrect.

Cell membrane cannot control reproduction.

Hence, option (2) is incorrect.

The main constituents of cell membrane is lipids and proteins, not sugars.

Hence, option (3) is incorrect.

Cell membrane regulates diffusion, because the cell membrane contains the semi-permeable membrane which allows only lipids and certain small molecules in the cell.

Hence, option (4) is correct.

Therefore, the Cell membrane regulates diffusion, in both plants and animal cells.

Answers

Answer:

a. is the energy required for molecules to react with each other

Explanation:

Activation energy may be defined as the extra energy required to start a reaction and the conversion of reactants into its products. It is the energy required to energize or activate molecules or atoms to undergo a transformation or a chemical reaction.

It is necessary for all types of chemical reaction to proceed. With the help of a catalyst the reaction rate increases as the energy of activation lower for the reaction to start.

Endocytosis: Endocytosis is the process by which cells take in substances from outside of the cell by engulfing them in a vesicle.

Phagocytosis: Phagocytosis, process by which certain living cells called phagocytes ingest or engulf other cells or particles.

Pinocytosis: Pinocytosis, a process by which liquid droplets are ingested by living cells.

Exocytosis: Exocytosis is the process by which a large amount of molecules are released; thus it is a form of bulk transport.

The correct answer is "Two identical DNA molecules are made that contain one original strand and one paired strand."

Explanation:

The word "conserve" refers to the action of preserving an element. Moreover, the prefix "semi" refers to partial. In this context, DNA replication can be considered as a semi conservative process because the original DNA is partially preserved. This is explained in "Each of the two daughter molecules made during replication contain one strand from the parent molecule and one new strand" because this excerpt shows how in the process each of the cells resulting has at least 50% of the DNA of the original cell. This implies replication does not lead to a completely new cell as part of the genetic material is kept. According to this, this process can be considered as semiconservative because "Two identical DNA molecules are made that contain one original strand and one paired strand."

Answers

Answer: Answer below, hope this helps! :D

Explanation:

A conjugated protein is a protein that functions in interaction with other (non-polypeptide) chemical groups attached by covalent bonding or weak interactions. ... The non-amino part of a conjugated protein is usually called its prosthetic group. Most prosthetic groups are formed from vitamins. Hemoglobin is a protein having a globular structure. Based on its structural properties, hemoglobin can be divided into two parts; a protein part and a heme group. The structure of the protein part can be studied at four levels; primary structure, secondary structure, tertiary structure, and quaternary structure.

Zara had a birthday and was able to choose a pet. The pet that she chose was a beautiful clownfish named Bozo, a common salt water fish. Zara already has a tank with goldfish at home. Use your knowledge of diffusion & osmosis to tell Zara how to take care of Bozo.

Answers

Answer:

See the answer below

Explanation:

The advice I would give  to Zara would be that she should keep Bozo in a separate tank with common salt water away from the goldfish. Bozo is a salt water fish while the goldfish can only survive in freshwater.

If Bozo is kept in a saltless water/freshwater tank with the goldfish, the water would be hypotonic to Bozo. Consequently, water will osmotically diffuse into the cells of Bozo, the cells would become turgid and lyse, and this would lead to the death of the fish.

If the goldfish is kept in the same salt water tank with Bozo, the salt water would be hypertonic to the goldfish. Consequently, water will osmotically diffuse out of the cells of the goldfish into the surrounding salt water, the cells of the goldfish would become flaccid, and this would lead to the death of the fish.

Skim the headings and bold words in this section. Write four steps scientists might take to solve a problem.

Answers

Answer:

1) Create a hypothisis 2) Create experiment 3) collect data 4) write conclusion

The four steps that a scientist uses to solve a problem are creating hypothesis, experiment, data sorting and writing conclusion.

What are hypothesis?

A hypothesis is an elaboration posited for a characteristic. The scientific technique requires that a hypothesis be testable in order for it to be considered a scientific hypothesis.

Scientists typically base scientific hypotheses on previous findings that cannot be adequately explained by existing scientific theories.

Any process that co-ordinate system data into some defined order to make it simpler to understand, analyze, or visualize is referred to as data sorting.

The conclusion is the final section of an academic essay. The conclusion should restate your response to the question and briefly summarize key points. It does not contain any new points or information.

A scientist solves a problem by developing a hypothesis, conducting an experiment, sorting data, and writing a conclusion.

Thus, by using these steps, scientist can come to an end for the problem.

Mitosis is the process by which the overwhelming number of cell divisions in eukaryotic organisms occur. Eukaryotes (animals, plants and fungi) typically consist of literally trillions of cells, and at any time, countless worn-out, dead or irreparably damaged body cells need to be replaces. Mitosis is the eukaryotic answer to binary fission in the single-celled prokaryotes, which is similar on the surface but simpler at the level of details.
