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.

Hello There!

Mosquitoes can often transmit viruses from one organism to another, acting as VECTORS of the virus.

Answer

(D). vectors​ is a correct answer

Explanation:

The first embryophytes were bryophytes, which include mosses and liverworts. They are considered the first land plants to have the capacity to form an embryo within protective structures. However, they lack the vasculature system seen in higher-order plants.

The first embryophytes in the plant kingdom were bryophytes. Embryophytes are land plants that include all green plants, ranging from mosses to lush green trees. The term 'embryophyte' primarily refers to plants that are capable of forming an embryo within protective structures. The first plants to evolve this ability were bryophytes, which include mosses and liverworts.

These plants don't possess a vasculature system as seen in higher-order plants (pteridophytes, gymnosperms, angiosperms), and they don't produce seeds. Bryophytes are mostly distinguished by their life cycles, characterized by dominant gametophytes stage. They reproduce via alternation of generations where the dominant phase is the haploid gametophyte, which is contrasted with the vascular plants where the sporophytes are the dominant stage.

Answer:

A; Half Aa and Half aa.

Explanation:

If you make a punnett square, the two genotypes will be Aa and aa, each half.

(sorry about the messy pic)

Answer:

Answer choice F

Explanation:

Since albinism is a recessive characteristic, let's assume that it has the "aa" alleles, so an individual who does not have albinism would have the "AA" alleles if he were homozygous and "Aa" if he were heterozygous.

If an albino (aa) female were to mate with a heterozygous, non-albino (Aa) male, we could fill in a punnet squad to determine what the offspring would be like. As we can see in the punnet square attached below, the result of this crossing would be 50% offspring "Aa" and 50% offspring "aa".

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.

Answer: A. A group of organisms with a shared ancestor

Explanation:a group of organisms believed to have evolved from a common ancestor, according to the principles of cladistics.

Clades are important because they represent a natural way to classify organisms based on their evolutionary relationships. A clade includes all of the organisms that descended from a common ancestor, and can be further divided into smaller clades based on more recent shared ancestry.

Clades are often identified by certain shared characteristics, such as genetic traits or physical features, which are known as "synapomorphies."

Synapomorphies are traits that evolved in the ancestor of a clade and were then passed on to all of its descendants. By looking for synapomorphies, biologists can identify the members of a clade and distinguish them from other groups of organisms that do not share those traits.

One of the key benefits of organizing organisms into clades is that it allows scientists to make predictions about the characteristics of organisms that have not yet been discovered. By knowing the traits of a clade's common ancestor, scientists can infer what traits its descendants are likely to have, and can use that information to guide their search for new species.

By organizing organisms into clades, biologists can gain insight into the history of life on Earth, and better understand the relationships between different groups of organisms.

Thus,  Clades also help researchers better understand the patterns and processes of evolution, and provide a framework for studying the diversity of life on Earth.

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.

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.

Answer:

C

Explanation:

Answer:

The correct answer is option B, that is, chlorophyll breaks down, exposing other pigment molecules we normally don't see.

Explanation:

Leaves are colored because of the presence of the molecules known as pigments. Chlorophyll is the pigment, which makes the leaves to appear green. Chlorophyll is an essential element for plants as it helps the plant to synthesize food with the help of sunlight.  

At the time of summer and spring, when there is enough amount of sunlight available, the plants produce loads of chlorophyll pigment. However, in autumn when it begins to get cooler, some of the plants stop producing chlorophyll, and those plants dissociate chlorophyll into smaller constituents. With the diminishing of chlorophyll, the other pigments begin to show their colors, and thus, the leaves turn red or yellow at the time of fall.  

Children of abusive parents often learn to be aggressive by imitating their parents. This illustrates the impact of cause and effect.

Sunny~ ☺

The children of abusive parents often learn to be aggressive in behavior by imitating their parents. This behavior is an illustration of the Operant conditioning.

Operant conditioning is also known as the instrumental conditioning. It is a type of associative learning process by which the strength of a behavior of an individual is modified by the reinforcement or punishment given by their parents. It is also a procedure which is used to bring about the learning of children.

Operant Conditioning is concerned with the non-reflexive and voluntary behaviors that are under the control of learners, and deals with the rewarding or punishing target behaviors of an individual to increase or decrease their manifestation.

Four essential quadrants of Operant Conditioning Theory include Positive Reinforcement, Positive Punishment, Negative Reinforcement, and Negative Punishment.
