The variations in the lemming population illustrate
A. the impact that population cycles have on predators
B. the ways in which a lack of food drives species to extinction
C. the benefits that generalist predators have over specific predators
D. how land animals have different population cycles than marine creatures
Answer: A) The impact that population cycles have on predators.
Explanation:
When a prey species is rare, food and space are plentiful, and its population increases rapidly. Meanwhile, the population of predators that feeds on it grows only once the prey population is big enough to fuel expansion
The variations in the lemming population illustrate the "impact that population cycles have on predators".
What is lemming populations change?lemming population cycles are driven by the predatory attentions of the least weasel (Mustela nivalis), which in turn shows a 'predator'-type cycle. Although lots of lemmings fall prey to owls, arctic foxes and suchlike, this isn't what makes their numbers oscillate.
What is population cycles ?A population cycle would be a generally periodic change in such a population's size or makeup over time. The population's component structure, such as its division into different age groups, is referred to as composition in this context.
Hence , A is correct option

Imagine a marked increase in dissolved carbon dioxide in warm shallow waters, where coral reefs exist. How could the increase in dissolved carbon dioxide MOST LIKELY affect the diversity of this ecosystem?
Question 4 options:
Aquatic plants die because they are unable to carry out photosynthesis under the new conditions.
The increased carbon dioxide causes an increase in dissolved oxygen also and more animals migrate to the area.
These are perfect conditions for coral reefs, which support a vast diversity of living organisms.
Some organisms are unable to withstand the reduced pH levels and die.
Some organisms are unable to withstand the reduced pH levels and die because the carbondioxide in water makes the water acidic.
What is the effect of dissolved carbondioxide in water?Ocean acidification occurs when the carbondioxide gas is dissolved in water that have negative effects on many marine species especially on coral reef which provides habitat and food for many organisms.
So we can conclude that some organisms are unable to withstand the reduced pH levels and die because the carbondioxide in water makes the water acidic.

Students model codominance in fish. B is the allele for blue coloring, and R is the allele for red coloring. They draw three fish with different-colored scales and fins. Their drawings are shown in the table.
Select the boxes to show the genotypes for each fish shown.
The phenotype of the fish when both R and Bl are present will be Blue and Red while the genotype will be BR.
What is co-dominance?Co-dominance in genetics is the condition in which alleles of a gene are both dominant in that when both are present in an organism, the organism will show the phenotype of both alleles.
Since the alleles B for blue coloring, and R for red coloring are both dominant, when both are present in the fish, the phenotypic coloring in the fish will be blue and red.

The organisms will be classified as producers, primary consumers, and tertiary consumers respectively.
Trophic levelsThese are the positions of organisms in the food chain in an ecosystem.
Producers are organisms that produce their own foods by photosynthesis. Thus, oak trees are producers.
Primary consumers feed on producers. Moths feed mostly on plant nectars. Some parasites feed on plants while others feed on animals. Thus, parasites can classify as both primary and secondary consumers while moths can only classify as primary consumers.
Secondary consumers feed on primary consumers. Thus, animal parasites will classify as secondary consumers.
Tertiary consumers are usually predators that feed on other animals. Thus, owls and weasels which are known carnivores will classify as Tertiary consumers.

Based on the recommended levels issued by the EPA, water in which region has been subject to the best stewardship?
Take a moment to click the start button on the simulation. Let it run for about 1 minute (the clock hand will complete 1 rotation) and then click stop. What did you notice coming from the plant?
a) sugar
b)bubbles
c)flowers
Bubbles are observed in the simulation after 1 minute due to the production of oxygen by plants during photosynthesis.
What is photosynthesis?Photosynthesis is the process by which green plants manufacturer their food from carbon dioxide and water using sunlight as am energy source.
In the process of photosynthesis, sugar is produce and oxygen is given off as a by-product.
Oxygen being a gas produces gas bubbles.
Therefore, in the simulation, bubbles are observed after 1 minute due to the production of oxygen by plants.

Sasquatch is used as a secret word. So the correct option is C.
What is meant by a secret word?Sasquatch, also known as Bigfoot, is a big, hairy, human-like monster that some people believe to exist in the northwest United States and western Canada. The name Sasquatch comes from the Salish se'sxac: "wild men." It appears to be the North American equivalent of the mythological Yeti, or Abominable Snowman, that inhabits the Himalayan area.
Many claims that the first set of Sasquatch footprints was found in 1811 by the British explorer David Thompson. Since then, hundreds more purported prints have been shown. The tale has also been aided by reports of sightings visually and even supposed photos and films (most notably those by Roger Patterson in Bluff Creek, California, in 1967), however, none of the reported proof has been independently authenticated.
The description of the sasquatch varies, but it is typically characterized as a primate that is 6 to 15 feet (2 to 4.5 meters) tall, standing upright on two feet, frequently releasing an unpleasant odor, and either traveling silently or crying out loud. Up to 8 inches (20 cm) in breadth and 24 inches (60 cm) in length, footprints have been recorded. Although most scientists are unaware of the Sasquatch's existence, a Soviet scientist named Boris Porshnev proposed that the creature and its Siberian equivalent, the Almas, may be extinct Neanderthals.
Therefore the correct option is C.

What property of water describes the molecule as acting like a tiny magnet?
Answer:
Intermolecular forces
Water is a dipole and acts like a magnet, with the oxygen end having a negative charge and the hydrogen end has a positive charge. These charged ends can attract other water molecules.
The entire electron densities of the two hydrogen atoms get attracted towards the oxygen atom. Thus a polarity develops in each O−H bond, and therefore, the water molecules are polar in nature and act like little magnets.
