Answer:

D. display an asymmetrical body plan

Explanation:

Most of the animals have bilateral symmetry but sometimes animals show asymmetrical body plan.

Rest of the options are wrong.

Animals are always multicellular and there is no exception to this fact. So, if we will write  sometimes animals are multicellular, it will be a wrong statement.

Animals are eukaryotic organisms so it means that they must have membrane-bound organelles .The organisms which do not have membrane-bound organelles  are known as prokaryotes but animals are eukaryotes. So B statement is wrong.

All the animals are heterotrophs that means that animals cannot produce their own food in any situation so statement C is also wrong.

Answer:

Display an asymmetrical body plan

Explanation:

The Answer is D. The sun's large mass causes it to have significant gravitational force, holding planets in their orbital paths. The moon does not effect this pull, as the sun's pull is much stronger than the moon's. The moon is responsible for the tides of the Earth, and it in fact rotates around us.

Answer:

The Sun's large mass causes it to have significant gravitational force, holding planets in their orbital paths.

Explanation:

Scientists have long established that the solar system is held together by the gravitational force of attraction between the bodies in space.

According to scientists, the magnitude of the gravitational force of attraction depends on the relative masses of the bodies. The larger the masses of the bodies the greater the gravitational force of attraction.

Hence the large mass of the sun causes it to have a large and significant gravitational pull on the planets thereby holding them in their orbital parts.

The living organisms in an ecosystem are called biotic factors whereas the non living are called abiotic

examples include:

abiotic: rain, wind, sunlight, and soil

biotic: trees, animals, and fungi

The correct answer is - C. Humans.

The stickleback in Loburg Lake, Alaska, is not a native species of the lake. It is thought that this fish was introduced to this lake somewhere between 1984 and 1989. The reason for this kind of suggestion is that the stickleback in this lake had full armor like the stickleback in the seas, which is not something found among the lake populations of this species. Also, the full armor had gradually been reducing with each new generation, and in the present, the stickleback in this lake looks totally the same as the other lake populations.

The stickleback did not had any predators in Loburg Lake, thus the losing of the full armor as it was not needed, instead the stickleback was the predator. But even though it didn't had a predator in the water, the humans became its predator through the recreational fishing that takes place on this lake.

The two main phases are interphase and mitosis

As far as my knowledge goes, the yellow area is mitosis, and mitosis is a process of cell division which results in two new nuclei (each containing a complete copy of the parental chromosomes)

D. the cell is dividing

Answer:

D. The cell is dividing.

Explanation:

Cell cycle is a series of events that leads to development of two daughter cells from a parent cell. The two main phases of cell cycle are interphase and mitosis. Interphase is the longest phase of cell, while mitosis takes much less time than interphase.

During interphase cell prepares for division and replicates its DNA, while mitotic phase involves actual cell division. During mitosis, division of nucleus and cytoplasm takes place to form two daughter cells.

Thus, the correct answer is option (D).

Explanation:

A deciduous forest is a biome dominated by deciduous trees which lose their leaves seasonally. The Earth has temperate deciduous forests, and tropical and subtropical deciduous forests, also known as dry forests. Another name for these forests is broad-leaf forests because of the wide, flat leaves on the trees. Trees in tropical deciduous forests lose their leaves in the dry season and regrow them in the rainy season. In temperate deciduous forests, trees lose their leaves in the fall and regrow them in the spring.

Final answer:

Gravity and inertia are the two factors that maintain the orbits of the Earth around the sun, and the moon around Earth, providing the equilibrium for their movements in space.

Explanation:

The factors that keep the Earth in orbit around the sun and the moon in orbit around Earth are gravity and inertia. Gravity is the force of attraction between two masses, which in this case are Earth and the sun, and Earth and the moon. Inertia is the tendency of an object to remain in uniform motion unless acted upon by an external force. The balance between gravity pulling the celestial bodies towards each other and inertia trying to keep them moving in a straight line is what keeps them in their respective orbits.

The correct answer between all

the choices given is the second choice or letter B.

The gravitational force between A and B compared to A and C is three-eighths, calculated by the ratio of the product of their masses and the square of their distance apart, according to Newton's law of universal gravitation.

The question involves gravitational force, which can be calculated using Newton's law of universal gravitation. This law states that the gravitational force (F) between two masses (m1 and m2) is directly proportional to the product of their masses and inversely proportional to the square of the distance (r) between them. The formula is:

F = G * (m1 * m2) / r2, where G is the gravitational constant.

Given that sphere A has twice the mass of sphere B, and sphere C has one-third the mass of A, we can assign mass values relative to B (e.g., A = 2B, C = 2/3B). Since the distance between A and C is half that between A and B, the force between A and C is affected by the square of this factor (1/2)2 = 1/4.

Thus, the force between A and C is stronger by a factor of 4 relative to the force between A and B.

By comparing the ratio of the two forces given the masses and distances, we can find that the gravitational force between A and B is actually three-eighths that between A and C (since (2B*C)/(B*2B) times 4 (the factor from the distance being halved) simplifies to 3/8). Therefore, the correct answer is C) The gravitational force between A and B is three-eighths that between A and C

Sexually reproducing organisms have two sets of genes for every trait. Offspring inherit one allele for each trait from each parent, thereby ensuring that offspring have a combination of the parents' genes.

A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. However, many genes do not code for proteins.

Type I genes tend to be involved in immune response or sensory receptors while type III genes are involved in cell to cell signalling and type II genes are a complex mix of all three types.

There has been two eons in the Earth's geologic history so far, the Precambrian eon, and the Phanerozoic eon. The eons are the basic and by far longest units on the geological time scale, spreading over hundreds of millions of years.

The Precambrian eon is the eon that starts with the formation of the Earth, up until the development of multi-cellular organisms. A very important event in this eon can be considered the formation of the Earth's oceans, which later enabled the conditions for the development of life. The organisms that dominated this eon are the one cellular organisms.

The Phanerozoic is the eon in which the multi-cellular organisms started to develop and evolve. This eon started with the end of the Precambrian eon, 543 million years ago up until the present. A very important event in this eon is the change of the composition of the atmosphere, which enabled the terrestrial life, as well as the better living conditions for the marine life. It is very hard to choose a dominant form of life in this eon, but worthy of mentioning are the plants, the sinapsids, dinosaurs, mammals, fish.

Final answer:

Metals form bonds by giving up electrons, creating a sea of delocalized electrons that allow for metallic bonding, responsible for metals' distinctive properties such as conductivity and malleability.

Explanation:

The correct answer to this question about the bonding behavior of metals is D. Metals tend to form bonds by giving up electrons. In metallic bonding, atoms of metals lose their valence electrons into a shared 'sea' throughout the solid. This allows metals to conduct electricity and heat due to the delocalized electrons that freely move through the structure. The metallic bonds formed between metal atoms allow for their characteristic properties, such as malleability, ductility, and high electrical and thermal conductivity. Furthermore, the malleability and ductility of metals find their origins in the resilient metallic bonds that bind atoms together, underscoring the multifaceted nature of metallic bonding.

From the food they intake in different ways such as Plants or other animals such as insects which are their fuel

Final answer:

Animals obtain chemical energy from food molecules like glucose through the process of cellular respiration, which transforms energy stored in food into ATP.

Explanation:

Chemical Energy in Animals

Animals obtain their chemical energy primarily from the food they eat. Unlike plants, animals cannot produce energy through photosynthesis, so they get their energy from food molecules like glucose. This process is known as cellular respiration, where energy stored in food is converted into a usable form, ATP. Cellular respiration can be either aerobic, involving oxygen, or anaerobic, without oxygen. The primary components of food that provide this energy are carbohydrates, fats, and proteins.

Organisms that cannot perform photosynthesis, like animals, depend on the consumption of other organisms to meet their energy requirements. They rely on a process that extracts the energy necessary to sustain their metabolism and to fuel their bodily functions such as muscle movement and cellular processes.

Its  chlorophyll pigment would be adapted to utilizing the blude-green spectrum of sunlight for photosynthesis rather than the red spectrum like land plants. This is because red light is absorbed by the oceans and does not reach greater depths (this is why oceans appear blue). These plants would therefore appear red in color.

Plants that live in the oceans have air-spaces in their leaves that that help them stand upright in water. They use buoyancy for structural integrity. This is why even long plants such as kelp seem to be upright in water (but will collapse when put on land).

A neutron has no charge

NEUTRAL = NONE

well thats how I remember it anyway

SO ITS NUMBER 2

A neutron has no electrical charge and is electrically neutral. Neutrons are part of the atom's nucleus alongside protons and provide mass to the atom without influencing its net electric charge.

The correct answer is that a neutron has no electrical charge. Neutrons, like protons, reside in the nucleus of an atom. While protons have a positive electrical charge, and electrons have a negative electrical charge, neutrons are electrically neutral. The neutron's lack of charge means that it does not contribute to the electrical characteristics of an atom. Essentially, neutrons provide mass without affecting the charge.

It is noteworthy that although a neutron itself is uncharged, it is composed of smaller particles called quarks, which do have electric charges. However, the sum of the charges of the quarks inside a neutron is zero, which is why the neutron is electrically neutral.
