Answer:

Answer:

The bottleneck effect is an extreme example of genetic drift that happens when the size of a population is severely reduced. Events like natural disasters (earthquakes, floods, fires) can decimate a population, killing most individuals and leaving behind a small, random assortment of survivors.

Answer:jellyfishes, corals, anemones, and ctenophora.

Explanation:

Examples of animals that possess bilateral symmetry are: flatworms, common worms ("ribbon worms"), clams, snails, octopuses, crustaceans, insects, spiders, brachiopods, sea stars, sea urchins, and vertebrates.

Answer:

C

Explanation:

Answer:

pH is a measure of the concentration of H3O+ ions in a solution. Adding an acid increases the concentration of H3O+ ions in the solution. ... If an acid is added to a basic solution, the solution becomes less basic and moves toward the middle of the pH scale. This is called neutralizing the base.

A lack of trees, a lack of biodiversity, and extreme circumstances are what most clearly identify the tundra.

The polar ice caps and the boreal woodlands (also known as taiga), it is located. Extremely low temperatures and barren, icy terrain define the tundra biome. The arctic tundra and the alpine tundra are the two different forms of tundra.

The Tundra Biome: The Ice Deserts of the World. The tundra is the coldest biome, with an average annual temperature of less than 5°C and yearly precipitation of less than 100 mm, most of it snow.

Only a few number of plants and animals can even thrive on the tundra due to its extreme weather conditions. The Finnish term "tunturia" is where the word "tundra" originates.

Therefore, a lack of trees, a lack of biodiversity, and extreme circumstances are what most clearly identify the tundra.

Answer:

The human appendix may be considered as a vestigial organ as it has been proved that the removal of the organ after infancy does not create any harm. Vestigial in that sense means that the vermiform appendix seemingly has no functions or is useless now but they might have had functions previously which are lost someway due to evolution.

Explanation:

Vestigial organs are organs, tissues or cells in a body which are not functional anymore the way they were in their ancestral form of the trait. It is therefore authentication of evolution and hence were helpful in explaining adaptation.

Carbon is transfered by plants and animals.

Carbon flows between plants and animals, environmental storage centers that absorb and store carbon for long periods of time. Thus, the correct option is A.

Carbon cycle is one of the main biogeochemical cycles which has four main steps. In this first, carbon enters into the atmosphere as CO₂. CO₂ is absorbed by the autotrophs such as green plants for photosynthesis. Then, the animals consume plants as food, thereby, incorporating the carbon into their system. Afterwards, animals and plants die, their bodies decompose and the carbon is reabsorbed back into the atmosphere.

In this, plants use carbon dioxide for photosynthesis. Through this, they remove the inorganic carbon from the atmosphere and incorporate it into the plant's tissues in the form of sugars such as glucose, sucrose and starch. Animals get carbon by eating the plants or by hunting other animals.

Therefore, the correct option is A.

Answer:

In the alveoli, where there is high pO2, low pCO2, lesser H+ concentration and lower temperature, the factors are all favourable for the formation of oxyhaemoglobin, whereas in the tissues, where low pO2, high pCO2, high H+ concentration and higher temperature exist, the conditions are favourable for dissociation of oxygen from the oxyhaemoglobin. This clearly indicates that oxygen gets bound to haemoglobin in the lung surface and gets dissociated at the tissues
