Found: A Plant-Eating Spider. Spiders are meat-eaters. Until recently, scientists thought that was true for the roughly 40,000 spider species in the world. Now, researchers have discovered a spider that eats mostly plants. Bagheera kiplingi, a jumping spider, lives in Central America and Mexico. It nests in the leaves of acacia tree. Scientists have long known that ants live in these trees. The ants eat the tree’s little yellow vegetables. But scientists had no idea that the spiders eat the vegetables too. Is competition likely to occur between the Bagheera kiplingi and ants living in acacia trees? Support your answer. *

Answer:

Precambrian era is the longest era in the Earth's history.  It began 4600 million years ago and ended about 540 million years ago.

Explanation:

Precambrian era makes up the vast majority of Earth's history. So, the correct option is D.

The majority of the history of the planet occurs during the Precambrian epoch. The Precambrian, which occurs before the current Phanerozoic Aeon, is the earliest period in Earth's history. The Cambrian, the earliest period of the Phanerozoic Aeon, is named after Cambria, the Latinized name for Wales, where rocks of this era were first investigated, hence the name "Precambrian."

The Precambrian period is known as the "Age of Early Life." The Precambrian period saw the formation of continents, the emergence of our current atmosphere, and the evolution and flourishing of early life. The world's oceans were home to soft-bodied animals like worms and jellyfish, while the land remained sterile.

Therefore, the correct option is D.

Answer:

I think the number of buffalo should reduced,for the grass to grow better and act as the food for buffalo

If the food source is affecting the buffalo population, the number of buffaloes in the area should decline.

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

Anything that affects the population of any species, it definitely reduces the number of specific species in a particular area. Then the affecting resource has the chance to spread in a much better way.

Therefore, if the food source is affecting the buffalo population, the number of buffaloes in the area should decline.

Answer:

The reason why earthquakes sometimes occur in the same locations as mid-ocean ridges and rift valleys securely is:

Explanation:

Earthquakes are caused by the release of energy that occurs regularly at the edges of tectonic plates, which with their movement allow the release of said energy, which later translates into an earthquake. In simpler words, imagine that tectonic plates are pieces of a domino together next to each other trying not to leave space, each union between one piece and another is a possible focus of energy release if these pieces move, and if that happened, whatever was on them would feel an earthquake or tremor.

There are places that are much more prone to earthquakes than others, for example, San Andreas Fault, which is heard a lot by the great earthquake it could cause in California.

Answer:

Faults form because crust gets cracked when plates move apart along divergent plate boundaries.

Answer: percentage of mice that will be spotted is 100%, and 0% chance of being solid colored.

Explanation:  First, homozygous means each parent have matching chromosomes (Like XX, instead of Xx)

Lets make a punnet square and show the data. We will use 'S' for spotted and 's' for solid

The punnet square shows that the percentage of mice that will be spotted is 100%, and 0% chance of being solid colored.

Hope this helps :)

The percentage of mice that will be spot-ted is 100%, and 0% chance of being solid colored.

In the first time, h-o-m-o-z-y-g-o-u-s means each & every parent should have matching chromosomes (Like X-X, instead of X-x)

So based on this, we can say that The percentage of mice that will be spot-ted is 100%, and 0% chance of being solid colored.

in this way, the percentage is determined.

Explanation:

C.) Ridges are the feature that separates watersheds.

A watershed is a region or area of land that collects and drains water into a particular river, stream, or other body of water.

Ridges or high points of land are critical in separating watersheds because they provide the boundary or border between two adjacent watersheds. When rain falls or snow melts, the water will flow downhill towards the closest body of water.

However, if that body of water is separated from another by a ridge, the water will flow down opposite sides of the ridge, into different watersheds.

Ridges are created by geologic processes such as tectonic uplift or erosion, and can vary in size and height. In some cases, a single ridge can divide a large drainage basin into two or more smaller ones, each with its own unique set of characteristics and ecosystems.

The boundary or border of a watershed is formed by a ridge or high point of land that separates one watershed from another. Water that falls on one side of the ridge flows into one watershed, while water that falls on the other side of the ridge flows into a different watershed.

B. A group with 30 DD parrots, 40 Dd parrots, and 30 dd parrots.

A group with 30 DD parrots, 40 Dd parrots, and 30 dd parrots is most likely in Hardy-Weinberg equilibrium.

The Hardy–Weinberg principle, also known as the Hardy–Weinberg equilibrium, model, theorem, or law, states that allele and genotype frequencies in a population will remain constant from generation to generation.

The Hardy-Weinberg equilibrium is a principle stating that the genetic variation in a population will remain constant from one generation to the next in the absence of disturbing factors.

For populations in the Hardy-Weinberg equilibrium, the equation connects allele frequencies to genotype frequencies. This equation allows us to compare a population's genetic structure in reality over time to the expected genetic structure.

Lung

Explanation:

Lungs expand to pull oxygen into the body and contract to push it back out. The larynx is known as the voice box which is an air way passage to the lungs and a pharanx is membrane lined cavity behind the nose and mouth. Neither of these really expand or contact during inhalation so the answer is Lungs.

Carbon is also found in the atmosphere where it's a part of carbon dioxide gas emitted when fossil fuels are burned and when living organisms breathe. It's in organic matter in the soil, and it's in rocks. But far and away the most carbon on Earth is stored in a surprising place: the ocean.

Answer:

Explanations:

Homeostasis can be defined as the phenomenon whereby there is balance or stability within the internal and external environment of a cell or the body. The internal environment of the organism is kept constant during homeostasis. During this process there is adjustments in the

internal environment Because there is always change in the conditions inside and outside the cell. When the system of the body is able to adjust itself it's reffered to as homeostatic regulation.

The endocrine system which contains glands that is responsible for the secretion of hormones into the bloodstream play also vital part during Homeostasis, This is because hormones which are the chemical messaged effect some change cells in another part of the body. The endocrine system is responsible for the regulations of

metabolism as well as the development of some body cells and systems via feedback mechanisms, hormones such as

Thyrotropin-Releasing Hormone during Homeostasis. Therefore as Joey eats strawberries for lunch the hormones makes adjustment of muscle metabolism and also regulate fluid and ion concentration in the system or body

Answer:

The simulation only shows how a population can change overtime in response to the changes in the environment. During the industrial revolution, one particular phenotype of moths had an advantage over the other and hence, was subjected to natural selection. What this simulation does not tell us is the causality and correlation aspect of the change that occurs in the moths. Correlation does not equal causation, and the simulation does not shed any light on these variables in this case.
