Answer:
D) There are many different enzymes known, each catalyzing one or more specific chemical reactions.
Explanation: Neither of them...
The biological catalyst that speeds the rate of reaction is called enzymes. The enzymes produce a substance at the end of the reaction, called a product. Thus, option B is correct.
What are enzymes?Enzymes are substances made of proteins and are involved in catalyzing the biological and chemical processes without undergoing changes.
They through the active site to the substrate to form a complex and as a result a product. This complex leads to conformational changes that produce another substance.
The active site of the enzyme is unique and different for various substrates. The enzymes are protein in nature and not lipids. The product produced has different chemical and physical properties.
Therefore, in option B. the enzymes produce products at the end of the reaction.

The Great Pacific Garbage Patch is an area in the north Pacific ocean that contains trash and causes harm to ocean life and those that consume that life. What lessons can be learned from this floating pile of trash?
Answer:
See the answer below
Explanation:
The lessons that can be learned from this floating pile of trash is that indiscriminate disposal of waste into the environment by humans can eventually come back to haunt them.
What led to the floating pile of trash is the indiscriminate disposal of wastes into the environment. These wastes eventually find their way to the ocean, damaging the aesthetic appearance of the water, poisoning aquatic biodiversity, and eventually poisoning the humans that consume the aquatic foods that make it out of such water alive.
The lessons that can be drawn from this floating pile of trash are that humans' indiscriminate disposal of waste into the environment can come back to them.
What is Pacific Garbage Patch?A collection of marine debris in the North Pacific Ocean is referred to as The Great Pacific Garbage Patch.
The indiscriminate disposal of wastes into the environment is what resulted in the floating pile of trash.

Sister chromatids separate during
O metaphase
O anaphase
O telophase
O prophase
Answer:
metaphase
Explanation:
Metaphase leads to anaphase, during which each chromosome's sister chromatids separate and move to opposite poles of the cell. Enzymatic breakdown of cohesin — which linked the sister chromatids together during prophase — causes this separation to occur.

Which of the following statements shows an example of operant conditioning?
Answer:
I think it's - A chicken learns that if it pecks on a button, a food pellet will be released into its cage.
The statement "A chicken learns that if it pecks on a button, a food pellet will be released into its cage" shows operant conditioning. So, option A is correct.
Operant conditioning, often known as instrumental conditioning, is a teaching strategy that use rewards and penalties to different behavior. Through operant training, actions that are rewarded are more likely to be repeated than actions that are penalised.
Pavlov's experiment with the dog is an example of classical conditioning, In classical conditioning, the stimulus that is repeatedly combined with the unconditioned stimulus until it finally elicits the same response is known as the conditioned stimulus.
Learning a skill by watching someone else perform it is an example of observational learning. Learning through observation of other people's behaviors is observational learning.

Scientists who study the anatomy of the systems in the human body focus on the structure of the organ and organ systems of the body. So the correct option is D.
What is anatomy?Anatomy is a field of biological sciences that studies the description of body structure and their identification of living beings. Anatomy also studies the relationship of these structures with one another.
Gross anatomy is referred to the major body sections in a narrow sense after dissection. The body structures studied under gross anatomy are simply those that are big enough so that their observation does not need any kind of magnifying device.
Microscopic anatomy is the study of structures which can only be observed with the help of a microscope.
In all kinds of anatomical research, dissection is necessary because it's not really possible to study internal structures without opening them. The earliest record of the study of anatomy is from the Greeks, in fact, the word anatomy is derived from the Greek word ana temnein which means to cut-open.

Which statement describes one characteristic of index contour lines?
O They appear thinner and lighter than other lines on a map.
They show regions where a difference in elevation exists.
O They show the locations of roads and paths on the landscape.
They show ratios used to determine the actual distance on a map.
On a topographic map, an index contour line is a darker, or bolder, line that typically appears every fifth line. To help to read the topographic map easier, the particular elevation is written beside these index lines. Thus, option A is correct.
What describes one characteristic of index contour lines?On a topographic map, a contour line is a line drawn to denote a dip or elevation of the ground. The vertical separation or elevation difference between contour lines is known as a contour interval. Every sixth contour line has an index contour, which is a bolder or thicker line.
Index contour. A contour line that is heavier, darker, and marked with an elevation. A change in elevation is typically indicated every fifth line. This makes it simpler to read the map.

Soups chemical synaptic transmission.
Sparks direct electrical transmission.

Intercellular communication refers to the communication and interaction that exists between two cells in the body. It could be hormonal or synaptic transmission.
Synapse is the site where electric nerve impulses are transmitted between two nerve impulses.
There are two synapse possibilities which are electrical and chemical.
The Sparks and soups mean that the scientific discovery over the transmission of nerve impulses as to whether they are electrical impulses (Sparks) or chemical impulses(soup).
Chemical synaptic transmission means there is no physical touch in the space chemical are released and move to the neighbouring cells.
Electrical transmission means neuron physically touch and give way for flow of impulses between cells.

Homeostasis se define como un estado de relativa estabilidad dentro del medio interno de un organismo, teniendo composición y propiedades definidas dentro de un rango, las cuales deben ser cumplidas para asegurar el correcto funcionamiento del medio interno. Es precisamente el asegurar el correcto funcionamiento lo que hace importante que las condiciones internas permanezcan dentro de un rango constante.

What is binary fission?In biology, fission is the division of a single organism into two or more pieces, followed by the regeneration of those parts into new, distinct organisms that resemble the original.
Asexual reproduction by splitting a body into two new bodies is known as binary fission.
When an organism divides into two halves (cytokinesis) through binary fission, it doubles its genetic material, or deoxyribonucleic acid (DNA), with each new creature acquiring one copy of the latter.
Divide into two is what binary fission refers to. It is the most straightforward and typical kind of asexual reproduction.
Thus, the correct option is A as it is showing the splitting of one cell into two.
