Some students conduct an investigation in a biology lab by setting up four different artificial stomachs, each in a
40 °C water bath. The students place the same amount of boiled egg white, a protein-rich source, in each stomach.
They also add dilute hydrochloric acid, HCl, and pepsin, a digestive enzyme, to each stomach, as shown in the table.
The students observe the mass of egg white in each stomach every 15 minutes.
Which statement describes the most likely result of this investigation?
A. The mass of the Egg white increases as the volume of the enzyme increases.
B. The egg white is unaffected by the differing amount of enzyme.
C. Digestion decreases in each stomach as more of the egg white's surface area becomes exposed.
D. Digestion increases as the volume of the enzyme increases.

Some Students Conduct An Investigation In A Biology Lab By Setting Up Four Different Artificial Stomachs,

Answers

Answer 1

Answer: D. Digestion increases as the volume of the enzyme increases.

Explanation:

Enzymes speed up reactions by reducing the activation time of a reaction. If there are more enzymes therefore, the reaction will move faster.

Pepsin is an enzyme that prefers acidic conditions so it can work with dilute HCL. It can also work in temperatures of 40 °C without getting denatured. As more Pepsin is added therefore, the reaction will move faster and digestion will increase.

Deforestation leads to environmental imbalance. Give reason.

Answers

Answer: Well, deforestation is cutting down trees, and many arboreal animals live in those trees. So if they have no proper shelter, they would have no place for personal activities such as breeding, feeding etc. And without those important activities that they have to do everyday, the population of arboreal animals will keep on decreasing until they go extinct. Though that's not the only problem. The herbivores won't get anything to eat, hence not letting the omnivores or carnivores get their food. As you can see, deforestation can create a huge environmental imbalance.

Which level of organization forms the fundamental base for all other levels
in the hierarchy of life? *
Cell

O Tissue
Organ
Organism

Answers

Answer:

organ

Explanation:

The highest level of organization for living things is the biosphere; it encompasses all other levels. The biological levels of organization of living things arranged from the simplest to most complex are: organelle, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystem, and biosphere.

The biological level of organisation range from organelle to biosphere. Therefore, option (A) cell  forms the fundamental base.

What do you mean by hierarchy of life ?

Cells join to form tissues in larger animals, which are clusters of similar cells performing similar or related jobs. Organs are groups of tissues that work together to fulfill a certain task. Organs can be found in both plants and animals. An organ system is a more advanced level of organization made up of organs with similar functions. 

A population is the aggregate term for all members of a species that are present in a given location. An ecosystem is made up of all the living things that exist in a specific location as well as the abiotic, non-living elements of that environment, such as soil nitrogen or rainwater. The biosphere is a group of organisms that is organized at the highest degree possible.

Thus, option (A) cells forms the fundamental base for all other levels

in the hierarchy of life.

BT crops are developed by adding traits from which of the following organisms?


phytoplankton

Answers

Answer:

bacteria

Explanation:

'Bt' crops are genetically modified crops that contains a certain gene of a bacteria called Bacillus thuringiensis. The name of this GM or transgenic crop was coined from the bacteria used.

The gene coding for the toxic traits of the bacteria are added into Bt crops e.g cotton, hence, the crops become resistant to pest attack. Therefore, according to this question, BT crops are developed by adding traits from BACTERIA.

If 22% of a DNA sample is made up of cytosine, C, what percentage of the sample is made up of adenine,
A?

Answers

Answer:

28% of Adenine

Explanation:

Chargaff's Rule states that A = T and C = G

Because of that, the sample must have the equation:

A + C = T + G

G must have the same amount as C so,

A + .22 = T + .22

Both sides of the equation must equal each other by .50, so .50 - .22 = .28

.28 x 100 = 28%

If 22% of a DNA sample is made up of cytosine, C, the percentage of the sample is made up of adenine, A is 28%

What is DNA?

The DNA sequence is the sequence or pairing of DNA bases. RNA and DNA both are genetic materials and both are made up of nucleic acids made up of deoxyribose acid and iron is made up of ribonucleic acid.

DNA and RNA both contain four bases that are joined with hydrogen bond RNA contain uracil in the place of thymine and DNA contain timing all other bases are the same.

Chargaff's Rule states that A = T and C = G

Because of that, the sample must have the equation:

A + C = T + G

G must have the same amount as C so,

A + .22 = T + .22

Both sides of the equation must equal each other by .50, so .50 - .22 = .28

.28 x 100 = 28%

Therefore, the percentage of the sample is made up of adenine, A is 28%

A student crested a model to show the flow of energy in a terrestrial ecosystem.

Which of the following correctly describes the way energy enters and leaves the ecosystem?

A Energy enters the ecosystem as sunlight, which is used by plants to produce sugars Energy leaves the ecosystem as heat from plants, herbivores, carnivores, and decomposers
B Energy enters the ecosystem from decomposers and is used by plants to produce sugars Energy leaves the ecosystem during cellular respiration
C Energy enters the ecosystem when it is transferred from the herbivores to the plants. Energy leaves the ecosystem as heat from plants, herbivores, carnivores and decomposers
D Energy enters the ecosystem as sunlight, which is used by plants to produce sugars. Energy leaves the ecosystem as mineral nutrients​

Answers

The flow of energy in the terrestrial ecosystem is initiated by the sun and its flows to plants and then animal life and finally reaches the decomposers. Thus the option A is correct.

What is an ecosystem?

An ecosystem is an ecological unit and its function is to balance the flow of energy in the environment. The flow of energy is unidirectional and as energy flow in one direction, it cannot be destroyed completely as it changes its form.

The energy that is received from the sun is transferred to the green plants, they include this energy to animals that are producers to consumers that include primary consumers and secondary consumers to decomposers, and then this energy leaves the system.

what are the two main types of chemical bonds?​

Answers

Answer:

Chemical bonds include covalent, polar covalent, and ionic bonds. Atoms with relatively similar electronegativities share electrons between them and are connected by covalent bonds. Atoms with large differences in electronegativity transfer electrons to form ions. The ions then are attracted to each other.

Two of the strongest forms of chemical bond are the ionic and the covalent bonds. Chemical bonds form between two atoms, each with its own electron environment.

Cause: Solar wind particles interact with Earth’s  upper atmosphere → Effect: An aurora is created

Explanation:

I have been able to drag the tiles to the correct boxes to complete the pairs.

When there is a trapping of radioactive solar wind particles in bands by the earth's magnetosphere, it becomes dangerous to travel in space through the Van Allen. Cosmic rays and solar particle add up to the additional hazards that it poses. A Van Allen radiation belt is known to be a zone  where energetic charged particles are found. Most of the energetic charged particles originate from the solar wind.  The solar wind  are captured by and held around a planet by that planet's magnetic field.

When the solar wind interacts with the earth's atmosphere, there is a collision of atoms of oxygen and nitrogen from the earth's atmosphere. The energy that is formed is a colorful glowing halo which is known as an aurora.
