What can be classified as
macronutrients,micronutrients,and water
Final answer:
Macronutrients include carbohydrates, proteins, lipids, and water, which the body needs in relatively large amounts. Micronutrients include vitamins and minerals that the body needs in smaller amounts.
Explanation:
Macronutrients are nutrients that the body needs in relatively large amounts. They include carbohydrates, proteins, lipids, and water. Carbohydrates are the body's main source of energy and can be found in foods such as bread, rice, and potatoes. Proteins are essential for growth and repair of tissues and can be found in foods like meat, fish, and beans. Lipids, also known as fats, provide energy and insulation and can be found in foods like butter, oil, and nuts. Water is essential for many bodily functions and can be obtained from beverages and foods with high water content.
Micronutrients are nutrients that the body needs in smaller amounts. They include vitamins and minerals. Vitamins are organic compounds that help regulate various physiological functions in the body. They can be obtained from a variety of foods such as fruits, vegetables, and dairy products. Minerals are inorganic substances that are necessary for proper bodily functions. They can be found in foods like meat, dairy products, and leafy greens.

Answer:
1. B
2.B
3.B
4.C
5.C
6.C
7.A
Explanation:
B. Bacteria can exchange genes for resistance to antibiotics in this way. Bacteria can take up genetic material from other bacteria or the environment during a process called transformation. This is relevant to humans because we can modify bacterial ADN with a gene of our choice and due to this transformation process, other bacteria can take up this modified ADN. B. All animals are heterotrophs. This means we can not produce food for ourselves inside our bodies. Instead, we have to consume it from another source in nature, for example, animal meat, fruits or vegetables.B. Species have specific adaptations to their local environment. In Darwin's finches for example, he found out that very similar birds had different peaks and head shape. He wanted to find out why they were so different yet so similar. He found out that depending on the food source available on the environment, the birds had a particular shape of peaks and head so they can feed properly.This adaptations and changes allow the birds to survive in a particular local environment.C. Mutualistic relationship. A mutualistic relationship is a biological interaction in which both organisms benefit. In this particular case, the Dinoflagellates provides energy to the coral and the coral protects the dinoflagellates against predators. This question is the same as the 4th one.C. recessive. The recessive hypothesis exposes that viruses were intracellular parasites that lost the required genes for replication and maintenance. So, they depend on host cells and their replication genes and processes to live.A. Analogous structure. An analogous structure is a trait that has a similar role, but whose origin is different. In this particular case, the insects, birds, and bats have different origins and ancestors but they all evolve wings to fly.3. Roads in urban areas are generally
Answer:
parallel and intersect at right angles
Explanation:
The roads in the urban areas tend to be very well organized and constructed. They tend to be parallel to each other, and also to intersect at right angels. The reason for this kind of building of the roads in the urban areas is to make the movement in the urban areas much easier and more efficient, mostly putting the accent on the traffic. It is a fact that the traffic is a big problem in the urban areas, so by constructing the roads in a well organized manner, the traffic jam eases up and the citizens can move more easily and quickly.

What causes differences in air pressure? the windchill factor the horizontal movement of air the speed at which wind moves the unequal heating of Earth’s atmosphere
Answer:
D) unequal heating of the earths atmosphere
Explanation:
Can't explain taking timed test, But I did get this question correct in an assignment.
Hope this helped!
Have a good day!
The unequal heating of Earth's atmosphere causes differences in air pressure. Hence, option D is correct.
What is air pressure?Everything you touch is pressed upon by the weighty air that surrounds you. This pressure is referred to as air pressure or atmospheric pressure. It is the force that the air above a surface applies to it while gravity pulls the surface toward Earth. A barometer is frequently used to measure atmospheric pressure.
The molecules and atoms that make up the many layers of the atmosphere are continually moving in arbitrary directions. Despite their small size, when they hit a surface, they apply pressure that humans perceive as a force.
The unequal heating of Earth's atmosphere causes differences in air pressure. Hence, option D is correct.

The DNA double helix is antiparallel. This means that the two strands
A. are parallel and are identical to each other.
B. cross over each other many times.
C. are parallel and run in opposite directions.
D. are parallel and are the mirror images of each other.
C. are parallel and run in opposite directions.
Explanation – Deoxyribonucleic acid (DNA) is double stranded molecule present inside the nucleus of the cell and has double helical symmetry. The two strands run or proceeds antiparallel to each other which means that one strand proceeds from 5' to 3' direction while the other strand proceeds from 3' to 5' direction.
It so happens because the nitrogenous base from one strand binds to its complimentary base pair of the other strand. Hydrogen bond is the bond that connects nitrogenous bases of two strands.

All organisms on earth require energy to live. Which statement best describes how ferns,
people, and flatworms obtain energy?
A.Ferns produce ATP during photosynthesis, while flatworms and people produce ATP
during digestion.
B.Ferns and flatworms absorb food from their surroundings, while people must digest food
found in their surroundings.
C.Producers such as ferns do not require a source of energy, while flatworms and humans
must consume food for energy.
D.Ferns produce glucose that can be broken down by cellular respiration, while flatworms
and people digest foods containing glucose for use in cellular respiration.
Answer:
A.
Explanation:
Ferns are a type of plant, therefore the way they obtain will be the same way as any other plant: by creating energy (ATP) during photosynthesis.
Flatworms cannot create their own energy, they're not autotrophic. Therefore, they must obtain energy by digesting any food they may find.

HELP!! Are the Earth's ocean floor and continents the same age geologically? Why or why not?
Answer:
No, the ocean floor is much younger because new crust forms there.
Explanation:
The Earth's ocean floor and the continents are not the same age geologically. The ocean floor is much younger because new crust forms there. New crust is usually formed at the oceanic spreading centers. This process takes place when the oceanic plates pull apart, and molten lava wells up from the mantle to fill the openings. This effectively functions as a recycling system for the oceanic lithosphere.

What statement correctly compares chemical reactions with nuclear reactions?
Chemical reactions involve the transfer or sharing of electrons without changing the nuclei, while nuclear reactions involve changes in the nucleus, leading to different elements and the release or absorption of a massive amount of energy.
Explanation:Chemical reactions and nuclear reactions differ fundamentally in the processes and changes that occur at the atomic level. In a chemical reaction, electrons are transferred or shared between atoms, leading to the formation and breaking of chemical bonds. However, during these reactions, the nuclei of the atoms remain unchanged, and the number of atoms of each element is conserved, indicating adherence to the law of conservation of mass. On the other hand, a nuclear reaction involves changes to the nuclei themselves, which can result in the transformation of elements and a notable release of energy.
Nuclear reactions often involve the rearrangement of nucleons (protons and neutrons) within the nucleus, leading to the emission or absorption of particles, such as alpha (α) particles, beta (β) particles, or gamma (γ) rays. These reactions are accompanied by enormous energy changes, far exceeding those of chemical reactions. Nuclear reactions can lead to a change in mass that, according to Einstein's equation E=mc², corresponds to a significant release or absorption of energy. Unlike the case of chemical reactions, in nuclear reactions the laws of conservation of mass and energy are not individually valid but are combined into the law of conservation of mass-energy.
The energy changes in nuclear reactions can be observed in processes such as fission, where heavy nuclei split apart releasing energy, or fusion, where light nuclei combine to form a heavier nucleus, also releasing energy. The amount of energy involved in nuclear reactions is orders of magnitude greater than for chemical reactions, illustrating the major difference in energy scales between the two types of reactions.
Some protists, called _______, can use sunlight to produce their own food but can also switch to consuming food from their environment.
A. chemotrophs
