What Is Behavior?
Behavior is a response to stimuli in the environment. Many animals use antipredatory
behavior to scare or startle
predators. This will either cause
the predator to leave, or give
the prey time to escape.

Which cell specimen is a prokaryote?
A Cell 1
B Cell 2
C Cell 3

Answers

Answer:

Cell 3

Explanation:

One of the unique main characteristics that differentiates a prokaryote from a eukaryote is the absence of presence of nucleus in their cell, and where their DNA is found.

In prokaryotic cells, nucleus is absence. The DNA of prokaryote is not found in a nucleus, rather, it is contained in a region referred to as nucleoid.

Therefore, the specimen that does not have DNA in nucleus is definitely a prokaryote.

Cell 3 is a prokaryote.

Answers

Answer:

Grass > Ant > Aardvark  > Hyena

Explanation:

The grass is autotrophic, which means it can produce its own food It does so using water, carbon dioxide, and light energy from the sun. The organisms in this food chain rely on other organisms for food.

The ant is a herbivore that consumes the grass for energy. The aardvark consumes both plants and animals (omnivore), so it can consume the ants. The hyena is a carnivore, meaning it only eats animals, such as the aardvark.

In this case, regarding the molecules:

Which are ammonium, ammonia and amide, in order to rank them in terms of how big the angles are, we need their molecular geometry as shown on the attached picture. As you can see, the geometry of ammonium is tetrahedral with an angle between H bonds of 109.5°, the geometry of ammonia is trigonal pyramidal with an angle between H bonds of about 107° and the geometry of amide is bent with angles of 104.5°.

Therefore the order from smallest to biggest is: NH₂⁻<NH₃<NH₄⁺.

You are asked to study a new inhibitor of oxidative phosphorylation. When it is added to a suspension of mitochondria carrying out this process, both ATP synthesis and oxygen consumption are inhibited. You suspect that the inhibitor blocks either the F-type ATPase or the electron transport chain. You can perform an experiment that measures the consumption of oxygen and the synthesis of ATP by isolated mitochondria. In one paragraph (6 sentences maximum), explain how the uncoupler, dinitrophenol, can be used to determine whether the inhibitor blocks the ATPase or the electron transport chain.
This was all the information that was given.

Answers

Answer:

DNP produces the loss of the proton gradient (i.e., the energy of the proton gradient is dissipated in the form of heat instead to produce ATP)

Explanation:

2,4-Dinitrophenol (DNP) acts to shuttle H+ ions across cellular membranes, bypassing the ATP synthase used by mitochondria to generate ATP during cellular respiration. Since DNP is able to bypass ATP synthase, this compound uncouples the phosphorylation of ADP by the ATP synthase from the process of oxidation (i.e., transport of electrons). For example, in muscle cells, DNP may be used to shuttle calcium ions (Ca +) from mitochondrial stores, and free intracellular Ca+ ions are evidenced to produce muscle contraction.

What is the Nervous tissue?​

Answers

Answer:

connective: Tissue that supports, protects, and gives structure to other tissues and organs in the body

epithelial: are widespread throughout the body. They form the covering of all body surfaces, line body cavities and hollow organs, and are the major tissue in glands.

muscle: Muscle tissue is composed of cells that have the special ability to shorten or contract in order to produce movement of the body parts. The tissue is highly cellular and is well supplied with blood vessels.

nervous: Nervous tissue is found in the brain, spinal cord, and nerves. It is responsible for coordinating and controlling many body activities.

Explanation:

Answer

Connective tissues gives support, protects and gives structure to other tissues and organs in the body.... example bone, cartilage, blood etc.

Epithelial tissues are spread throughout the body. Their functions include secretion (sweat, mucus), absorption (nutrients) and protection (tissues that lie beneath from radiation) in the body.

Muscle tissue is composed of cells that have the special ability to shorten or contract in order to produce movement of the body parts.

Nervous tissue is found in the brain, spinal cord, and nerves. It is responsible for coordinating and controlling many body activities.

The color of a star is determined most by its mass. Thus, option C is correct.

On which factor brightness of the star depends?

The brighter the star is, the closer it will be from the Earth. Hence, the brightness of a star depends upon the distance between the star and the Earth. The color of a star tells you how cool or hot it is. Blue colored stars are cool while red colored stars are hot (like sun).

A star is a celestial object that produces light and heat through nuclear fusion reactions in its core. Stars are made up of hot, dense gas and have their own gravity, which helps them maintain their shape. They are classified based on their temperature, size, and luminosity.

Most stars are part of a galaxy and are found in clusters called star systems. The sun is a star and is the closest star to Earth. Stars play a crucial role in the evolution of the universe and are essential for the formation and survival of planets, including Earth.

Therefore, The color of a star is determined most by its mass. Thus, option C is correct.

If the test is negative, one test will suffice for the 19 people (we are assuming that the pooled test will be positive if and only if at least one person in the pool has the desease); whereas, if the test is positive each of the 19 people will also be individually tested and, in all, 20 tests will be made on this group.
