A. near-Earth objects.
Explanation:
Science can be defined as a branch of intellectual and practical study which systematically observe a body of fact in relation to the structure and behavior of non-living and living organisms (animals, plants and humans) in the natural world through experiments.
When scientists discuss objects that might hit Earth, the term which they use to describe them as a group is near-Earth objects.
A near-Earth objects can be defined as a small solar system body such as comets and asteroids whose orbit draws it close or in proximity to the earth's orbit due to the gravitational force of attraction of nearby planetary bodies.
Basically, if the closest approach of a planetary body to the Sun is less than 1.3 AU it is considered to be a near-Earth objects.
Hence, near-Earth objects may pose a collision danger to planet earth.

Sea anemones are predatory invertebrates with stinging tentacles that can paralyze many sea animals. The clownfish is immune to the sting of the sea anemone and actually lives among its tentacles. The relationship is mutually beneficial—the clownfish often lures meat-eating animals over to the anemone, and the anemone benefits from the meal. The clownfish often gets to eat leftovers from the anemone’s meal.
When the clown fish is ready to lay eggs, it lays them near a sea anemone. How’s this a reproductive strategy?
Answers
The clownfish's reproductive strategy of laying eggs near a sea anemone is a form of protection and survival for its offspring.
By laying their eggs in close proximity to the sea anemone, the clownfish provide their eggs with a safe place to develop. The sea anemone's tentacles are a powerful defense mechanism that can fend off potential predators that may try to harm or eat the eggs.
In addition to protection, the clownfish also benefit from the relationship with the sea anemone during the reproductive process. The anemone provides a clean surface on which the eggs can be attached and also helps to oxygenate the surrounding water, which is important for the development of the eggs.
The anemone's tentacles also help to keep the eggs free of harmful parasites and fungi. Overall, the clownfish's reproductive strategy of laying eggs near a sea anemone is a mutually beneficial relationship that helps to ensure the survival of the clownfish offspring.
The protection and benefits provided by the sea anemone help to increase the chances of the eggs hatching successfully, resulting in a higher survival rate for the next generation of clownfish.

During the light reactions, the pigments and proteins of ____________ use light to send energized electrons through an electron transport chain, ultimately producing ____________ (a form of energy). A ____________ molecule replaces the lost electrons, producing the byproduct ____________ .
Answers
Answer:
The correct answer is - photosystem II; ATP; water; oxygen
Explanation:
The photosynthesis process involves two different cycles known as the light reaction and the dark reaction. In light reaction there are two photosystems; photosystem I and photosystem II.
During light reaction, there are several pigments such as chlorophyll a and other pigments present in photosystem II that trap the light and transfer excited electrons through ETC to produce ATP which is a form of energy used by cells.
A water molecule takes place of the excited electron that is transferred and releases oxygen as waste or byproduct in this reaction.
Aristo was riding in a car and noticed a pond that was covered in algal blooms due to excess phosphorus in the water. which of these other features in the landscape could be the reason for the high levels of phosphorus?many carscow pasturesolar panelsforest
Answers
Cow pasture is the reason for the high levels of phosphorus in the water resulting in algal blooms.
Algae blooms, also known as overgrowths of algae, occur quickly when phosphate and nitrogen levels are too high. Algal overgrowth burns oxygen while obstructing sunlight from reaching submerged plants.Although cow pasture (manure from cow dung) is frequently kept in enormous storage "lagoons," some of it unavoidably leaks into the groundwater and neighboring rivers, causing blue-green algae, or cyanobacteria, blooms.Commonly, runoff or soil erosion from fertilizer and manure introduces these nutrients. Toxic algal blooms may occur when these extra nutrients combine with hot sunny days. The blooms are harmful to people, animals, and fish.

The major functions of the plasma membrane do not include
Answers
Answer: The major functions of the plasma membrane do NOT include: a) separation of the fluid environments inside and outside the cell.
Explanation:
The development of the cell wall and cell plate is mediated by the Golgi complex. Vesicles are produced by the Golgi complex during the mitotic anaphase. Thus option E is correct.
What are the major function of plasma membrane?The primary role of the plasma membrane is to serve as a physical barrier between the interior organelles of the cell and the surrounding environment.
The plasma membrane is a selectively permeable membrane, allowing only a limited number of molecules to enter and exit the cell. They must pass through specialized channels or pores in the membrane.
Only specific molecules can pass across plasma membranes because they are selectively permeable (or semi-permeable), according to this definition.
It is simple for water, oxygen, and carbon dioxide to pass through the membrane. In general, ions (such as sodium and potassium ions) and polar molecules cannot diffuse freely through the membrane.
Therefore, major functions of the plasma membrane do not include cell wall formation.

There are three sources of genetic variation in sexual reproduction. Determine which of the following statements accurately describes which of these are considered random and which are not
Answers
Genetic recombination and independent assortment are considered random sources of genetic variation, while mutations can occur randomly or due to specific factors.
In sexual reproduction, the three sources of genetic variation are genetic recombination, independent assortment, and random mutations. Among these sources, genetic recombination and independent assortment are considered random processes, while mutations are not entirely random.Genetic recombination occurs during meiosis when homologous chromosomes exchange genetic material through crossing over. This process is considered random as the precise locations where recombination events occur are unpredictable.Independent assortment refers to the random alignment and separation of homologous chromosomes during meiosis I. The random positioning of maternal and paternal chromosomes contributes to genetic diversity in offspring.On the other hand, mutations are not entirely random as they can be influenced by various factors such as exposure to mutagens or errors in DNA replication. However, the specific mutations that occur at particular loci are generally considered random events.Therefore, the accurate statement would be that genetic recombination and independent assortment are considered random sources of genetic variation, while mutations are influenced by both random and non-random factors.For more such questions on Genetic variation:

which of the following best describes evolution? the disappearance of a species. there is competition for resources. a change in a population over time. survival of the fittest.
Answers
Survival of fittest best describes evolution. Evolution is the method by which a species changes over time to accommodate its environment.
Evolution is the shift in a biological population's heritable traits over successive generations. These traits are the expressions of genes, which are passed down through reproduction from parent to offspring. Genetic recombination and mutation frequently result in variation within a population. This variety is subjected to evolutionary processes like natural selection (including sexual selection) and genetic drift, which cause some traits to become more or less prevalent within a population. This is when evolution happens. Heritable traits evolve over successive generations as a result of shifting evolutionary forces that determine whether a trait is prevalent or rare within a population.
The phrase "survival of the fittest," popularised in Charles Darwin's fifth edition of On the Origin of Species (published in 1869), argued that animals most adapted to their environment have the best chances of surviving and procreating. In this theory, he provided an explanation of how to thoroughly and accurately characterise the mechanism and process of natural selection. The reproductive success of an organism can be used to gauge the effectiveness of this physical biology principle.

which measurement is likely the least accurate? Explain.
What observations and/or patterns do you see in the data?
Answers
Based on the information, we can infer that the measurement that could be the least probable is caudal peduncie depth strandard error. Also, the trend is for lake values to be higher than river values.
What difference do we see in the values in the table?To identify the values we must analyze the table and identify they are not the trends. In this case we can infer that the tendency is for the values of the lake to be higher than the values of the river because all the values of the lake are higher than those of the river.
On the other hand, we can infer that the value that could be the least successful is the peduncie depth strandard error because it shows equal values. However, if we take into account the previous values, it should not be the same in both cases.

From what you know of tonicity, what can you say about the plant cells and the solutions in the test tubes
Answers
Answer:
Tonicity is the relative amount of solutes that is dissolved in solution which determine the direction and level of diffusion.
Explanation:
Tonicity is the relative amount of solutes that is dissolved in solution which determine the direction and level of diffusion. There are three types of tonicity i.e. hypertonic, hypotonic and isotonic solution. If a cell is placed in a hypertonic solution, water will leave the cell, and the cell will shrink due to more solute in the external environment. In an isotonic environment, there is no water movement occurs, so there is no change in the size of the cell. When a cell is placed in a hypotonic environment, water will enter the cell, and the cell will swell. due to lower amount of water present inside the cell.
