Answer:
The kingdom Animalia, or Metazoa, includes all animals. Animals are multicellular, eukaryotic organisms, which are heterotrophic, meaning they obtain nutrition from organic sources.

Answer:
Among the seven characteristics in life, the one should be sensitivity. It is where living organisms detect and react to stimulus or changes to the environment.
Specifically among plants, this change is called a tropic response, or tropism for short. Plants reacts to aspects like light, gravity, or water.
This response is controlled by a plant hormone called auxin. Auxin is produced at the tip of the plant, and they diffuse among the plant. The auxin accumulates at the side of the plant that doesn't receive as much sunlight, and auxin can stimulate its growth on that side so the plant bends. That's how a plant bending works.
Anyways, the answer to the question should be sensitivity.
The correct option is (a) 2 → 4 → 1 → 3
A change occurs in the environment. → Poorly adapted individuals have decreased survivorship. → Well-adapted individuals leave more offspring than do poorly adapted individuals. → Genetic frequencies within the population change.

What is genetic variation in population?</h3>
- The presence of various alleles, or different gene versions, within a population indicates genetic variety.
- If there is genetic variation, then everybody in the population will have various genotypes depending on the alleles they carry.
- Genetic loci that have many alleles are said to be polymorphic. Human characteristics like blood type and eye color, for instance, are polymorphic.

The two alleles for fur color in snurfles are Yellow and Green. These alleles are represented by the letters G and g. Homozygous dominant GG is yellow, as well as heterozygous Gg. But recessive gg is green. These are the two colors that can be seen in the traits of fur colors in snurfles. I hope this helps.
Answer:
1. High osmotic pressure due to the hypersaline nature of marine habitats
2. The dependence of flowering plants on pollinating insects for fertilization. These insect pollinators are however, absent in the marine environment.
3. Competition from already-established sea weeds and grasses provides another challenge to flowering plants invadingnthe oceans.
4. Constant changes in the environment as well as temperature changes too
Explanation:
The marine environment is a hypersaline environment with a high salt concentration relative to that of the plant cell. Due to high salt concentration of the marine environment, their is high osmotic pressure on living oragnisms found therein. Organisms must have well-adapted osmo-regulatory mechanisms to counteract the high osmotic pressure of their environment. Therefore, flowering plants face the challenge of removing excess salt from their cells or else lose water to their environment, hence resulting in the death of the plant. However, most flowering plants lack this ability and thus, have found it difficult to invade the oceans.
Flowering plants depends on insect-pollinators for fertilization. However, these insect are not found in the oceans, and as such, it is difficult for flowering plants to invade the oceans.
Well-adapted seaweeds and grasses serve as competitors for any invading flowering plant. Since the flowering plants are not yet adapted for life in marine habitats, they lose out in this competition.
The oceans are constantly in a state of frequent turbulence and change due to tides and currents. Also, the temperature of the oceans are very low and fluctuations in the temperatures of the ocean do occur, utimately serving as obstacles to invading flowering plants to adapt to life in the oceans and seas.
