Answer:

cotyledons

Explanation:

cotyledons are the differnece and monocots has one cotyledons and dicots have two!

The number of cotyledons is a defining characteristic of the two different types of an angiosperm.

A cotyledon can be defined as a significant part of the embryo of a plant which is present within the seed of a plant, and it is defined as the embryonic leaf in the seed-bearing plants, one or more of these cotyledons are the first to appear from a germinating seed in a plant.

Number of cotyledons is the number of cotyledons which are found in the embryo of the plant, which is the actual basis for distinguishing the angiosperms into two major classes, and it is the source of the names such as Monocotyledonae or one cotyledon and Dicotyledonae or two cotyledons. The cotyledons are the seed leaves, which are produced by the embryo.

Final answer:

A disadvantage of social behavior is social loafing, where individuals contribute less in a group setting, leading to reduced group productivity. Additionally, technological influences on social behavior can risk social isolation and autonomic nervous system disorders.

Explanation:

One disadvantage of social behavior is the phenomenon of social loafing. Social loafing occurs when individuals in a group contribute less effort to a task than they would if they were working alone. This tendency leads to diminished productivity and output within the group, as some members might rely on others to pick up their slack. This behavior can negatively impact group dynamics and overall performance, making many individuals dread group work, particularly when tasks require equal participation from all members.

Moreover, social behaviors influenced by technology might contribute to social isolation, reducing face-to-face interactions and potentially leading to loneliness and depression. As individuals become more reliant on electronic means of communication and social media, there is a heightened risk of disorders related to the autonomic nervous system, which includes deficits in social engagement and the capacity for love.

Answer:

1. hypertonic 2.hypotonic 3.isotonic

Explanation:

The given statement is False.  

As the water velocity decreases, the size of the particles that the water can transport also decreases. For example, as the velocity of the stream increases, the stream can carry larger sediments. It is noted that the physically weathered sediments are bigger in particle size in comparison to the chemically weathered particles.  

In case, if the velocity of water is too slow and the slope is too gentle, then the rate of transportation of sediments also decreases and the sediments get to pile up.

Explanation:

From the chart you can teel that the most dense, coolest and saltiest waters can be found at the deepest levels of depth, in this case the deepest from the options would be located at less than 3,000 meters and it would be point C. As we know as we go depeer into the water of the ocean pressure increases and with that density of the water also increases, under normal circumstances the sunlight and sun heat is the only thing that is able to heat up the water of the ocean, so the deeper you go, the less sunlight and less sun heat is available so the waters become cooler.

The species of the habitat that are on the verge of extinction or perishment are called endangered species. Komodo Dragon is a group of animals that is endangered.

The species that are most likely to become perished in the future in a particular habitat or overall on the planet is called the endangered species.  This may be due to extensive hunting, habitat destruction or the introduction of non-native and competitive species.

The data about the killer whale population is deficient and cannot be categorized appropriately in the endangered category while Dinosaurs are extinct species.

Komodo Dragon is now considered an endangered species as their population had declined rapidly due to climate change and the decrease in the deer population which is their major prey are the most likely to make them vulnerable.

Jelly fishes a water loving creature, is composed of 3 layers:

- An outer layer also known as ectoderm

- A middle layer- composed of thick jelly like substance called mesoglea

- An inner layer  

The outer layer is covered with tentacles composed of stinging cells which are used to attack prey and for defense against the predators. There is present one single opening for mouth and anus.  

As explained, the body is covered with tentacles which help jelly fishes to attach and support themselves in movement. The type of locomotion jelly fish has is passive locomotion.

In genotypic terms, a hybrid organism is represented by a combination of both dominant (A) and recessive (a) alleles. Therefore, the option A. Aa symbolizes a hybrid organism.

In genetics, a hybrid organism is one that possesses a mix of characteristics. This is usually indicated by a combination of both dominant and recessive alleles in its genotype. So, symbolically, the option that represents a hybrid is A. Aa.

This pattern signifies a pair of alleles, where 'A' is dominant and 'a' is recessive. This results in a heterozygous genotype and is characteristic of hybrid organisms. Other options such as 'BB' and 'cc' represent homozygous genotypes and 'De' is not standard notation in genetics.

The given blank can be filled with Gestalt.

Explanation:

A school of thought, which looks at the mind of a human and behavior as a whole is known as Gestalt psychology. In making an attempt to produce the sense of the world surrounding us, the Gestalt psychologists suggest that one does not basically focus on every small constituent. However, the minds seem to perceive objects as part of the greater whole and as the constituents of more composite systems.  

This branch of psychology plays a prime function in the contemporary development of the study of human perception and sensation.  

A small duct known as the ureter connects the kidneys and bladder. The urethra is the cylindrical way that interfaces the bladder to the body's outside, permitting pee to leave the body.

Urine travels through the ureters from the kidneys to the urinary bladder, where it is temporarily stored. The urethra is a structure made of tubules that carries urine outside the urinary bladder.

There are three layers in the ureter: outer adventitia, muscularis, and the innermost mucosa. Circular transitional epithelium lines the mucosa. The waterproof properties are due to the keratin in this layer.

The primary contrast among ureter and urethra is that ureter channels pee from kidney to bladder while urethra channels pee from the bladder to the beyond the body.

Explanation:

Baby animals who live in trees, like squirrels and birds, are at high risk of being blown out of their nests and becoming lost, separated from their parents forever. One example is a litter of baby squirrels who were blown out of their nest and rescued by a Good Samaritan. “[I]f the animals had not been found they would have died within hours,” whether from shock or predators, the Daily Mail reported. But the news wasn’t all good for this squirrel family: sanctuary workers feared that their mother, whom rescuers could not locate, was still searching for her missing babies.

Birds are also in danger of death or dislocation from hurricanes. Some, like woodpeckers, know how to weather the storm — they stay in holes in trees. But migratory birds don’t fare as well. “Powerful winds from hurricanes and tropical storms can blow birds off course and push them hundreds of miles away from their home habitat,” according to the National Wildlife Federation (NWF). Some of them never make it back.

Non-migratory birds are in peril of losing their food sources. “Birds living in hurricane areas…suffer when their food supplies, such as fruits and berries, are stripped from trees and shrubs,” reports Birding.com. But at least the adults can stay put: their toes are designed to clench tight around branches, allowing them to resist even strong winds.

Sea mammals have it hard too. Kevin Coyle of NWF writes that “some dolphins and manatees have actually been blown ashore during major storms.”

Other sea life can suffer from the intermingling of salt and fresh water when a hurricane’s high winds cause storm surges, NWF explains: “[S]alty ocean water [piles] up and surge[s] onshore,” which “shifts the delicate balance of freshwater and brackish wetland areas. Creatures and vegetation that are less salt-tolerant will be harmed and many will not survive this influx of sea water.”

Final answer:

Fern reproduction requires two generations due to the alternation of generations in its life cycle, with a dominant sporophyte stage producing spores and a less visible gametophyte stage for sexual reproduction. This cycle ensures genetic diversity and adaptation to different environments.

Explanation:

Fern reproduction requires two generations due to its life cycle involving alternation of generations, which includes both sporophyte and gametophyte stages. The sporophyte generation is the more visible phase in ferns, characterized by leafy fronds with undersides dotted with clusters of sporangia, which produce spores. These spores develop into tiny, heart-shaped gametophytes, which are much less visible and contain reproductive organs called antheridia (producing sperm) and archegonia (producing eggs). Fertilization occurs when flagellated sperm swim to an egg within an archegonium, leading to the formation of a new sporophyte, thus completing the cycle.

The presence of two distinct generations, each fulfilling different roles in reproduction and survival, highlights the complexity of fern life cycles. This alternation of generations ensures genetic diversity and allows ferns to adapt to varying environmental conditions. The gametophyte stage, though less conspicuous, plays a crucial role in the sexual reproduction phase, while the sporophyte stage is dominant and responsible for spreading spores widely.
