Explanation:
" Yes, dolphins can understand the difference between seeing another dolphin and seeing their own reflection.
Dolphins are highly intelligent marine mammals with sophisticated cognitive abilities. They possess a level of self-awareness that allows them to distinguish between their own reflection and another dolphin. This has been demonstrated through the mirror test, which is used to assess self-recognition in animals.
In studies where dolphins have been exposed to mirrors, they have shown behaviors indicating that they recognize themselves. For example, they may investigate parts of their bodies that they cannot see without a mirror, suggesting that they understand that the reflection is of themselves. This level of self-awareness is a strong indicator that dolphins can differentiate between their own image and that of another dolphin.
Furthermore, dolphins use echolocation to perceive their environment, which provides them with detailed information about objects, including other dolphins. They can discern the difference between the echoes returning from another living dolphin and those from an inanimate object or their own reflection.
Therefore, based on scientific evidence and observed behaviors, it is concluded that dolphins do understand the difference between seeing another dolphin and seeing their own reflection."

How do protons contribute towards making ATP?...
Answer: Protons contribute towards making ATP by producing proton-motive force that provides energy for ATP synthesis.
Explanation: In the respiratory chain, the transfer of electrons from one complex to another is accompanied by pumping of protons out of the matrix. This creates a difference in proton concentration and separation of charge across the mitochondrial inner membrane. The electrochemical energy inherent in this difference in proton concentration called proton-motive force is used to drive ATP synthesis as protons flow back passively into the matrix through a proton pore.

the ability to move or cause changes in matter
Explanation:
Energy is defined in science as the ability to move matter or change matter in some other way. Energy can also be defined as the ability to do work, which means using force to move an object over a distance.
The ability to move or cause changes in matter is referred to as energy.
Explanation:
Energy is a fundamental concept in physics and the natural sciences. It is the capacity or ability to do work or bring about changes in the state or motion of matter. Energy exists in various forms, and these forms can be converted from one to another. Some of the common forms of energy include:
Kinetic Energy: This is the energy of motion. Any object in motion possesses kinetic energy, and the amount of kinetic energy depends on the mass and velocity of the object.Potential Energy: This is energy stored in an object due to its position or state. For example, an object raised above the ground has gravitational potential energy, while a compressed spring has elastic potential energy.Thermal Energy: Thermal energy is the energy associated with the temperature of an object. It is a measure of the total kinetic energy of the particles within a substance.Chemical Energy: This is the energy stored in the bonds between atoms and molecules. It can be released during chemical reactions.Electrical Energy: Electrical energy is the movement of electrons through a conductor and is harnessed to power various devices and systems.Radiant Energy: Radiant energy includes electromagnetic waves such as light, heat, and other forms of radiation.Energy is a fundamental concept because it underlies all physical processes and is conserved in closed systems. It plays a crucial role in our daily lives, powering everything from machines and appliances to biological processes within living organisms.

2. I
3. Sorry I am not sure.
4. I
Explanation:
1. ATP has 3 phosphate groups, T = tri aka three.
2. ATP has 3 phosphate groups and turns into ADP which as two phosphate groups because when it loses one phosphate, it releases energy.
3.
4. Passive transport does not require energy because when it passes through the cell membrane it is going with the concentration, it goes from high to low concentration. Active Transport requires energy because it is going against the concentration, low to high, so it needs energy to go from low to high concentration.
Answer:
1) A
2) I
3) C
4) I
Explanation: ATP is adenosine triphosphate. It has three phosphate groups attached to the 5th carbon atom of the ribose sugar. ATP contains adenine (a base), a ribose sugar and three phosphate groups.
ATP break down is an exergonic reaction in which the terminal phosphate group of ATP is cleaved to produce ADP and inorganic phosphate group (Pi) with the concomitant release of energy.
Cellular respiration involves the break down of a glucose molecules in the presence of oxygen to produce carbon dioxide, water as by-products with release of energy in form of ATP. The chemical energy in form of ATP released in cellular respiration is used to drive other cellular functions.
Passive transport is a process by which polar compounds and ions move across membrane through an alternative path created by membrane proteins. In passive transport, the transported species always move down its electrochemical gradient and does not require ATP expenditure. This means that passive transport is not coupled to ATP breakdown or does not occur at the expense of ATP hence the name passive transport. It is different from active transport which is coupled to ATP breakdown.
How many recessive genes does a individual need in order to show the recessive trait?
Answer: Two recessive genes
Explanation: Every trait is controlled by at least a pair of gene, one inherited from the mother and the other inherited from the father. A recessive gene is a gene whose effect is masked by a dominant gene. A recessive gene lacks the ability to express itself in the presence of a dominant gene. For a recessive gene to manifest outwardly, it must occur in a homozygous state that is the individual must inherit two copies of the gene from its parents, one from the mother and one from the father.

The abiotic factors that determine a terrestrial biome are weather, climate, latitude and amount of sunlight an area receives, and nutrients available.
The amount of precipitation and the warm climate in the tropical rainforest support more organisms in that area. There are fewer limiting factors in the tropical rainforest.
The order of most to least sunlight is littoral zone, limnetic zone, and profundal zone.
Biomes are different because of their differing latitude, climate, weather, amount of sunlight, and precipitation. All organisms have a range of tolerance for the temperature, amount of sunlight, and precipitation in which they can survive.
Explanation:
A mushroom gains it’s energy by decomposing the tissues of dead organism. Should mushrooms be classified as autotrophs, heterotrophs in both groups, or in neither group and for what reason?
A. They are autotroph because they do not eat their food , as animal do
B. They are autotroph because decomposition is very similar to photo synthesis
C. They are heterotrophs because their food is made by other organisms
D. They are both autotrophs and heterotrophs, because they may grow in sunlight or darkness
Answer:
Because mushrooms require obtaining food from other sources, it should be considered that they are heterotrophs because their food is made by other organisms (option C).
Explanation:
Mushrooms are the sporocarps of multicellular eukaryotic organisms belonging to the Fungi kingdom. Unlike plants -which are able to synthesize their own nutrients- mushrooms must acquire nutrients from organic matter, so they are considered heterotrophic.
The nutrition of mushrooms depends on their affinity for living organic matter -in the form of parasites or symbionts- or dead organic matter, performing its digestion through enzymatic degradation. The sporocarp that characterizes the mushrooms, is the visible form of development that can acquire a fungus.

Of these answer choices, which could be the cause of Down syndrome for an offspring?
A. The mother's egg contained 22 chromosomes.
B. The father's sperm contained 23 chromosomes.
C. The mother's egg and the father's sperm each contained 23 chromosomes.
D. The father's sperm contained 23 chromosomes and the mother's egg contained 24 chromosomes.
Answer: D). The father's sperm contained 23 chromosomes and the mother's egg contained 24 chromosomes.
Explanation: Down syndrome is a chromosomal disorder caused by an extra chromosome. Each gamete (sperm cells and egg cells) contains 23 chromosomes. During fertilization, a sperm cell with 23 chromosomes fuses with an egg with 23 chromosomes to form a zygote with 46 chromosomes. A normal child has 46 chromosomes but a child with down syndrome has 47 chromosomes. A child with down syndrome has an extra chromosome usually inherited from the mother, that is the mother's egg contains 24 chromosomes instead of 23 chromosomes.

Cold sores are caused by virus.
Describe why a virus such as the cold sore virus cannot be cultured on a nutrient agar plate
Answer:
Viruses in general require a living host cell for replication. So cold sore virus requires a livng host to replicate. Infected host cells can be cultured and grown, and then the growth medium can be harvested as a source of virus as compared to bacteria that can be cultured in a nutrient agar plate. So ther virus must have a host cell like bacteria, plant or animal in which to live and make more viruses. Outside of a host cell, viruses cannot function.
The cold sore virus cannot be cultured on a nutrient agar plate because viruses require a host cell to reproduce. Agar plates provide nutrients which viruses cannot utilize for growth.
Explanation:A virus, such as the one that causes cold sores, cannot be cultured on a nutrient agar plate due to the nature of its life cycle. Viruses are unique in the microscopic world because they cannot reproduce outside of a host cell. They lack the cellular components necessary for independent life and replication.
When performing culture techniques, bacteria and fungi (which are self-sufficient and can reproduce on their own) can be cultured on nutrient agar because they use the nutrients in the agar to grow and multiply. However, a virus requires the inside of a host cell, taking over the cell's machinery to produce more virus particles. The cold sore virus, specifically, replicates inside human cells, which means it cannot utilize a nutrient agar plate for growth.

These gametophytes produce the cells that are gametes which are pollen and ovule respectively. These grains fuse to form fertilization and zygote. The zygote marks the starting of the sporophytic generation.
The sporophytic generation is diploid and the gametophytic generation is haploid in nature.
Powerful thigh extensor when climbing stairs it can also laterally rotate and abduct the thigh
Answer:
It is true that powerful thigh extensor when climbing stairs it can laterally rotate and abduct the thigh, due to the combined action of the muscles that form it.
Explanation:
Thigh extensors are a group of muscles located in the front of the thigh, needed for walking, running, jumping, climbing stairs, or bending.
Thigh extensors form a combined structure, called the quadriceps femoris:
Rectus femoris.Vast medial or internal muscle.Vast lateral or external muscle.Vast medial muscle.In addition, the longest muscle of the muscular system, the sartorius, is found within the thigh extensors.
When climbing stairs, one of the functions of the thigh extensors is to produce the external rotation and abduction - midline separation - of the thigh, a function specifically performed by the vastus laterale muscle.

B.) ice
C.) water
D.) animal behavior
C.) WATER IS THE ANSWER!!
Answer:
c water is the answer
Explanation:
yeah
Water is the most common and powerful agent of erosion. Therefore, option (C) is correct.
What is erosion?Erosion is the process by which natural forces such as wind, water, ice, and gravity wear away and shape the Earth's surface. Water is the most common and powerful agent of erosion, as it has the ability to erode and shape the landscape in a variety of ways. Water erosion can occur through the action of flowing water, such as in rivers and streams, or through the action of waves and tides in the ocean. Water can also cause erosion through the process of groundwater seepage, in which water flows underground and erodes the soil and rock below the surface.
Water erosion can have a significant impact on the landscape, shaping valleys, carving out canyons, and creating features such as waterfalls and gorges. It is also a major factor in soil erosion, which can have negative impacts on agriculture and the environment.

if the killer whale obtained 26,000 joules of energy by eating the crabeater seal, how many energy was available at each of the following trophic levels of the food chain?
Energy available to killer whale: 26,000 joules
Energy available to crabeater seal: 260,000 joules (assuming a 10% energy transfer efficiency between trophic levels)
In ecological systems, energy transfer between trophic levels follows the 10% rule, meaning that approximately 10% of the energy is passed on to the next trophic level. In this scenario, if the killer whale obtained 26,000 joules of energy from consuming the crabeater seal, it can be inferred that the crabeater seal initially possessed 10 times that amount, or 260,000 joules.
This estimation takes into account the energy lost as heat, metabolic processes, and other inefficiencies as energy moves through different trophic levels in the food chain. Therefore, each trophic level typically retains only about 10% of the energy from the level below it, illustrating the energy dynamics within the ecosystem.

The statement best describes surface tension is a measure of the intermolecular forces that cause two different substances to attract one another.
What do you mean by surface tension?Surface tension is the tendency of liquid surfaces at rest to shrink into the minimum surface area possible. Surface tension is what allows objects with a higher density than water such as razor blades and insects to float on a water surface without becoming even partly submerged.
The surface tension determines the behavior of liquids in a number of processes and phenomena: Wetting and wettability: The wetting of a solid by a liquid depends, among other things, on the surface tension.
An example of such an organism is the water strider, which can run across the surface of water, due to the intermolecular forces of the molecules, and the force of the strider which is distributed to its legs.
