Cactus finches have long, pointed beaks. Say the only source of food for Cactus finches is cactus flowers. If a plant disease killed a large portion of the cacti on the Galapagos islands, how would the population of Cactus finches change

Answers

Answer 1

The population of the Cactus finches suddenly experiences a decline when a large portion of the cacti on the Galapagos islands was killed by a disease.

What do you mean by Population?

A population may be defined as the number of individuals of the same species living in a particular area at a given time.

Cactus finches only depend on the cactus flower as a food source, and if these flowers were killed by a disease, the cactus finches do not get enough food to survive and reproduce, hence their population may fall rapidly.

Therefore, the population of the Cactus finches suddenly experiences a decline when a large portion of the cacti on the Galapagos islands was killed by a disease.

Answers

Answer:

A lighting producing organ to attract mates and prey.

Explanation:

Camouflage would do very little for a fish that spends most of it's day in the middle of a dark ocean. Mimicking other deep sea creatures would actually be more of a disadvantage than an advantage, as the sounds would be more likely to scare away potential prey, rather than attract them. A light however, would attract the prey's curiousity and urge them to check out the light.

which sun is providing energy to this planet, and can the planet sustain life ?

Answers

Answer:

Without the sun's heat and light, life on Earth would not exist.

Explanation: The sun has extremely important influences on our planet: It drives weather, ocean currents, seasons, and climate, and makes plant life possible through photosynthesis.

Answer:

no it cannot sustain itself without the sun.

Animals need the sun for vitimin D plants need it to photosynthesis and in the few cases that this isn't the case those plants are parasitic and still need photosynthesing plants to get energy from. So by removing the sun we lose plants that many herbovore animals rely on then they starve resulting in lose of food for carnivores so they starve aswell. And any life left after that would most likely freeze.

cell wall
centriole
nucleus
cell membrane

Answers

The answer is Cell wall

The tough and rigid layer that surrounds plant cells, as well as some algal and bacterial cells, is called the cell wall. Therefore, the correct statement is option A.

What are the functions of cell wall?

The cell wall provides mechanical support to the cell, thereby, protecting it from damage caused by external factors. The cell wall consists of complex carbohydrates, such as cellulose, lignin, etc.

The cell membrane is selectively permeable, and the cell wall is porous allowing the passage of some molecules. The cell wall also helps in cell communication and signaling.

The cell wall determines the shape of the cell and helps in the regulation of growth and development. The thickness and composition of the cell wall change with respect to different environmental conditions and helps in the survival and function of many types of cells.

Therefore, the tough and rigid layer that surrounds plant cells is called the cell wall.

Answers

Answer:

Spraying plants with insecticides

The method of moth control would be most dangerous to the honeybee, which is needed for plant pollination is spraying plants with insecticides.

What is pollination ?

Pollination is the transfer of pollen from a plant's anther to its stigma, allowing fertilization and seed production, most commonly by an animal or by wind.

Pollination is the transfer of pollen grains from stamens, the flower parts that produce them, to ovule-bearing organs or to the ovules (seed precursors). Pollen is simply caught in a drop of fluid secreted by the ovule in plants where the ovules are exposed, such as conifers and cycads.

Pollination is the process of moving pollen grains from the anther to the stigma of the same or different flowers. Self-pollination and cross-pollination are the two types of pollination.

A species of moth has a 2 varieties of wing color: brown and white. As winter approaches, the trees where the moths live loose their leaves. The moth's predators are birds who hunt for the moths as they rest on the dark tree bark. Every moth lays 100 eggs, but only about 10 from each egg cluster live to adulthood

Answers

Assuming that this question makes reference to the survivability of the two moth variations, we can confirm that the brown-colored moth will be better adapted to survive in the winter months.

Why are the brown moths more likely to survive?

This has to do with their ability to better hide from predators. As described in the question, their primary predator are birds that hunt them while resting on the tree bark. This means that the white-colored moths will stand out against the dark tree bark and be easier prey for the birds. This will eventually lead to all the moths in the area being brown-colored through the process of natural selection.  

Therefore, we can confirm that the brown-colored moth will be better adapted to survive in the winter months due to their ability to hide from predators.
