Longitudinal must travel through a medium  is not true about Longitudinal waves.

Wave that advances in the same direction as a periodic disturbance or vibration is referred to as a longitudinal wave. A point on any coil of the spring will move with the wave and return along the same path, passing through the neutral position and then reversing its motion once more.

A coiled spring that is compressed at one end and then released experiences a wave of compression that travels its length followed by a stretching. In addition to compressing and rarefying the gas in the direction of the sound wave's path, sound waves traveling through air also cause them to vibrate back and forth.

Seismic waves in the P (primary) phase are longitudinal as well. Each particle of matter vibrates about its usual rest position in a longitudinal wave.

Therefore, Longitudinal must travel through a medium  is not true about Longitudinal waves.

Explanation:

it moves the warm current water from the north and south towards the equator

Warm currents move water from the equator to the cooler areas in the north and south. The correct option is d.

A continuous, directed movement of sea water caused by a variety of forces acting on the water, such as wind, the Coriolis effect, breaking waves, cabling, and temperature and salinity differences.

Wind, density differences in water masses caused by temperature and salinity variations, gravity, and events such as earthquakes or storms can all cause ocean currents. Currents are streams of seawater that flow through the ocean.

Water expands due to solar heat absorbed at the equator. Such heated water raises the normal sea surface level, and the resulting change in ocean topography can be measured.

Warm ocean currents flow from the equator to the poles, while cold ocean currents flow from the poles to the equator.

Thus, the correct option is d.

Explanation:

Soil formation is influenced by organisms (such as plants), micro-organisms (such as bacteria or fungi), burrowing insects, animals and humans.

As soil forms, plants begin to grow in it. The plants mature, die and new ones take their place. Their leaves and roots are added to the soil. Animals eat plants and their wastes and eventually their bodies are added to the soil.

This begins to change the soil. Bacteria, fungi, worms and other burrowers break down plant litter and animal wastes and remains, to eventually become organic matter.

Answer:

Limiting factor.

Explanation:

If the resource is necessary to the survival of a population and is needed to sustain it and allow the population to grow, it is a limiting factor. Simply put, limiting factors are defined as anything that constrains a population's size and slows or stops it from growing. Over use of resources can cause the species that need it to survive to die out and possibly become extinct if they can only be found in that ecosystem.

It is not a Biotic factor because biotic factors are described as a living organism that shapes its environment.  These can include plants like algae.

An abiotic factor is a non-living part of an ecosystem that shapes its environment.

Both of these are defined as factors in an ecosystem and are important. HOWEVER, the question is asking about resources in an ecosystem. Therefore Limiting factor is correct.

Answer: The Joker is a very popular character with boys, perhaps because laughter is part of their own “mask of masculinity.” A potential negative consequence of this stereotype is the assumption that boys and men should not be serious or emotional. However, researchers have also argued that humorous roles can be used to expand definitions of masculinity.

The Jock is always willing to “compromise his own long-term health; he must fight other men when necessary; he must avoid being soft; and he must be aggressive.” By demonstrating his power and strength, the jock wins the approval of other men and the adoration of women.

The Strong Silent Type focuses on “being in charge, acting decisively, containing emotion, and succeeding with women.” This stereotype reinforces the assumption that men and boys should always be in control, and that talking about one’s feelings is a sign of weakness.

The Big Shot is defined by his professional status. He is the “epitome of success, embodying the characteristics and acquiring the possessions that society deems valuable.” This stereotype suggests that a real man must be economically powerful and socially successful.

The Action Hero is “strong, but not necessarily silent. He is often angry. Above all, he is aggressive in the extreme and, increasingly over the past several decades, he engages in violent behavior.”

The Buffoon commonly appears as a bungling father figure in TV ads and sitcoms. Usually well-intentioned and light-hearted, these characters range from slightly inept to completely hopeless when it comes to parenting their children or dealing with domestic (or workplace) issues.

Explanation:

it occurs during meiosis. Its the exchange of chromosome pieces between the non-sister chromatids during the production of gametes.

Answer:

Crossing-Over is a DNA segment on each chromosome section may code for eye color, although one chromosome may code for brown eyes and the other for blue eyes. Crossing over occurs most often between different alleles coding for the same gene.

Explanation:

Answer:

The large eyed ducks had an undesirable trait, but the small eyed ducks have a desirable trait. Because the large eyed ducks had a trait that decreases their chances of survival, they wete killed. But small eyed ducks are lucky because they have a trait that increases their chance of survival. The small eyed ducks reproduce more offspring that have small eyes, but the large eyed ducks cannot because they didn't survive. This causes that the allele for large eyes in the gene pool to decrease.

Tree 3 depicts a different evolutionary history than the others. So, the correct option is C.

A phylogenetic tree is defined as a branching diagram or a tree that shows the evolutionary relationships between different biological species or other entities based on similarities and differences in their physical or genetic characteristics. All life on Earth is part of a single phylogenetic tree that points to common ancestry.

These relationships are identified by using the similarities in DNA, RNA, or protein sequences, or by comparing the anatomical features. Through this, we get to know that all life arises from a common ancestor. In the above given information, Tree 3 shows the phylogenetic relationship.

Thus, Tree 3 depicts a different evolutionary history than the others. So, the correct option is C.

Answer:

Genetic diversity refers to both the vast numbers of different species as well as the diversity within a species. The greater the genetic diversity within a species, the greater that species’ chances of long-term survival. This is because negative traits (such as inherited diseases) become widespread within a population when that population is left to reproduce only with its own members.
