Given what we know about the way energy moves through the Earth, we can confirm that the vulture uses the hot air currents that result from this movement of energy to soar above the cliff.

The energy from the sun travels through the atmosphere, then into the soil where it is absorbed. The soil then radiates the heat back out into the atmosphere.

Given that hot air rises, this radiated heat causes the formation of hot air currents that the vulture then uses to glide upwards in a circular motion.

The vulture planes over the hot air currents with its wings at an angle to climb, it goes higher the further it wishes to travel given that once at the desired height, it glides downward towards its destination.

Plant cells have a large central vacuole, while animal cells have many smaller vacuoles. Hence option c is correct.

Vacuole is defined as a region of cytoplasm-free, membrane-lined, and liquid-filled space inside a cell. A membrane-bound cell organelle known as a vacuole.  The plant cell's equilibrium depends heavily on the vacuole. It participates in the regulation of cytoplasmic ions, pH, and the control of cell volume and turgor.

Animal cells lack a cell wall, whereas plant cells do. Animal cells lack chloroplasts while those of plants do. Animal cells have many little vacuoles, but plant cells only have one giant vacuole. Animal cells only have a cell membrane, but plant cells have both a cell wall and a cell membrane. Cell walls are used by plants to give the plant structure. Animal cells lack the organelles known as chloroplasts that are present in plant cells.

Thus, plant cells have a large central vacuole, while animal cells have many smaller vacuoles. Hence option c is correct.

Answer: D: The distribution of many organisms has already shifted as a result of warming.

Explanation: I just took the quiz on FLVS

The statement that supports the biological predictions as it relates to change in climate is : ( D ) The distribution of many organisms has already shifted as a result of warming

Climate change is the long term change in the Average weather conditions of a region, province or territory. Climate change is associated to global warming caused by the activities of man which affects the weather conditions of a given region in the long term.  

As the climate continues to change, many organisms begin to redistribute themselves to regions with favourable weather conditions, and this is the biological prediction/effect of climate change on the environment.

Hence we can conclude that The distribution of many organisms has already shifted as a result of warming  is the correct statement.

Explanation:

Answer:

The similarity between ferns and humans is that both go through meiosis and mitosis. But ferns are different because they have multicellular, free-living haploid and diploid forms. In humans, the haploid stage exists in the form of single cells—sperm and eggs. Only the diploid stage that begins with a zygote grows mitotically to form a multicellular, free-living human.

Explanation:

Humans and ferns are similar as both of these organisms fertilize to reproduce while differs in the haploid form of life which is present in the ferns and the male and female reproductive parts present in humans.

The life cycle of fern includes the diploid fern which gives rise to the haploid spores that grows and form a gametophyte plant in which both the male and female reproductive systems are present. The male gamete undergoes fertilization with the female gamete to form a diploid spore (seed) which gives rise to the new fern plant.

Human’s reproductive cycle include diploid animals and the male and female genders which can be distinguished clearly. The male gamete-sperm fertilizes with the female gamete-egg to form the diploid zygote that gives rise to a new human.
