There are two species of freshwater shrimp that are introduced to a pond. The first species, Caridina cantonensis, is brightly colored with red and white stripes. The second species, Caridina multidentata, is more mottled drab in coloration. Fish have an easier time finding and eating Caridina cantonensis due to their bright colors. When each of these species reproduce they produce about 100 offspring, but only 30% Caridina cantonensis offspring survive to reproductive age, while 75% Caridina multidentata offspring survive to reproductive age.
A. In this situation what is natural selection selecting for?
B. In this situation what is natural selection selecting against?
C. How do you predict this population will evolve?
D. Identify how each of the listed conditions from the above scenario that influence natural selection. Population must have variation. Some variations are favorable More offspring are produced than survive Those that survive have favorable traits Differential reproductive success

Answers

Answer 1

Answer:

A. Colour of the freshwater shrimp

B. Predator fish problem

C. Based on the number of offsprings that has survived

D. Differential reproductive success

Explanation:

A. The freshwater shrimp species C. cantonensis is brightly coloured which is easy to find by fish whereas C. multidentata is mottled drab in colour which can hide in the environment. Therefore the natural selection will select for the mottled drab of the shrimp.

B. The mottled drab colour of the shrimp will be selected against the predator species which feeds on the shrimp population as the predator species can find the brightly coloured species easily but the mottled drab colour will not be found.

C. The population is evolving can be identified based on the number of population found in that area as 75% of C. multidentata species reach reproductive stage while only 30% of C. cantonensis reach the reproductive rate.

D. The condition will be known as Differential reproductive success.

What about these molecules requires them to have this tetrahedron shape?

Answers

Answer:

There are four atoms required for having tetrahedron shape.

Explanation:

Tetrahedron shape molecule is made up of four atoms. The structure of tetrahedron shape molecule is just like pyramid. One atom is present at the top while the remaining three atoms attached to it at the bottom with bond angles of about 109.5°. So the structure of molecules only be possible if the molecule is made up of at least four atoms and have four unpaired electrons. Examples of such molecules are methane, water and ammonia.

What anatomical features makes it possible for Homo erectus to be a biped runner. Pick only one feature discussed in this week's material that allowed Homo erectus to be a biped runner. How is your chosen feature different from Australopithecus aferensis equivalent feature? Briefly explain the difference. Lastly, I would like you to briefly explain in your own words how endurance running would enhance the fitness of the Homo genus.

Answers

Answer:

Explanation:

The early homo erectus had tendors, ligament and mass spring which enables them become adapted runner.

The mass spring is energetic contributing to high speed.

The mass spring is mechanism aids in the exchange of kinetic energy and potential energy in the presence of tendors and ligaments that stores up the energy this enables them to run.

Nocturnal ligament that is present in homo erectus the helps to keep the head in position is absent in Australopithecus. This ligament usually activated during running in erectus and makes running more convenient.

Endurance running helps the early homo's to survival as they often run to get preys and animals to feed on. Because they do not have all the tools needed to hunt, the need to move in close range to get the prey hunted.

The plane of Earth's orbit around the Sun is called the: ?

Answers

Answer:

its called The Ecliptic.

Explanation:

The plane of Earth's orbit around the Sun is called the "ecliptic plane." The ecliptic plane is an imaginary flat plane that represents the average path traced by Earth as it orbits the Sun.

The Ecliptic plane serves as a reference plane for locating the positions of celestial objects in the sky, including the Sun, Moon, planets, and stars. The ecliptic plane is inclined at an angle of approximately 23.5 degrees with respect to Earth's equator, giving rise to the changing seasons as Earth orbits the Sun.

Therefore, the ecliptic plane represents the average path of Earth's orbit around the Sun and serves as a reference for understanding celestial positions and movements. Its tilt plays a vital role in determining Earth's seasons, and its alignment with other planets enables various astronomical phenomena.

Explain how vaccines work? Using the words virus, immune system, white blood cells, memory cells and vaccine

Answers

Vaccines work by training the immune system to recognize and combat pathogens, either viruses or bacteria. In order to do this, certain molecules from the pathogen need to be introduced into the body to trigger an immune response. These molecules are called antigens, and they’re present on all viruses and bacteria. Memory cells are then formed to remember the same pathogen for faster antibody production in future infections. Vaccinations increase the level of circulating antibodies against a certain antigen. Antibodies are produced by a type of white blood cell (lymphocyte) called B cells.

2. Once the most populous species of its kind in North America, these were hunted to extinction by 1901.
3. When sailors stocked its island with pigs, the pigs destroyed this species' ability to reproduce.
4. This species was almost wiped out by collectors who prized its rarity.
5. Once a major resource in Canada, the population crashed in the 1990s. Recovery is slow because they cannot reproduce until age 7.

Answers

Answer:

Explanation:

Dodo- When sailors stocked its island with pigs, the pigs destroyed this species' ability to reproduce.

Canadian cod- Once a major resource in Canada, the population crashed in the 1900s. Recovery is slow because they cannot reproduce until age 7.

Rothschild's orchid-This species was almost wiped out by collectors who prized its rarity

Whales- Multiple species were almost wiped out, but are slowly recovering after a moratorium on hunting them.

Passenger pigeon- Once the most populous species of its kind in North America, these were hunted to extinction by 1901.

Overharvesting and using natural reservoirs including plants and animals, when their breeding rate is declining, is called overexploitation.

The correct matches are:

A. Dodo- Option 3. When sailors stocked its island with pigs, the pigs destroyed this species' ability to reproduce.

The influx of new animals in their territory and habitat destruction was the cause of the extirpation of the Dodo bird.

B. Canadian cod- Option 5. Once a major resource in Canada, the population crashed in the 1900s. Recovery is slow because they cannot reproduce until age 7.

They are now threatened species because of overfishing. Their breeding rate is also slow making them endangered species.

C. Rothschild's orchid - Option 4. This species was almost wiped out by collectors who prized its rarity.

The area in which the plant species thrives is now cleared and the plants are wiped out by collectors.

D. Whales- Option 1. Multiple species were almost wiped out, but are slowly recovering after a moratorium on hunting them.

Pollution, contamination and over whaling has led this variety to the verge of endangerment.

E. Passenger pigeon- Option 2. Once the most populous species of its kind in North America, these were hunted to extinction by 1901.

Their habitat loss and overexploitation for their meat are the main causes for which they went obsolete.

Explain why scientists the Albert and kaibab squirrels are examples of speciation

Answers

- Kaibab Squirrel gives us one nice example of the evolution that is caused by geographical isolation - about 10,000 years ago when the last Ice Age ended, physical formations in the valley changed in a way that prevented squirrels from reaching the Colorado River. The valley has become a geographical barrier separating forests and squirrels on each edge. One group of squirrels became two separate groups that were no longer able to mate, kaibab squirrels. Abert squirrels are North American species, found across a group of locations. Kaibab squirrels are a subspecies of Abert squirrels, found only in one region in the United States. - Kaibab and Abert squirrel live in ponderosa pine forests, where they build nests of twigs and pine needles. They eat nuts, fruits, and fungi, as well as seeds, bark and twigs from the trees they make at home. The most important source of food in the squirrel Kaibab is the seeds contained in the cones of ponderosa

Answer:

The Abert’s squirrel is found on the south rim of the grand canyon and surrounding states.

The Kaibab squirrel can only be found at the north rim of the canyon.

Scientists believe they were separated by plateau erosion that separated the forests of the Grand Canyon, isolating the Kaibab population of squirrels.

The population of rabbits could have overrun human population ordinarily, but the presence of limiting factors would hinder it.

The limiting factors are biotic and abiotic environmental factors that prevents the population of organisms from getting to their biotic potential. In other words, limiting factors will not let the population of organisms grow perpetually. These factors include:

Competition for limited resourcesDiseasesNatural disastersPredation

sitting in a chair getting hit with a reflex hammer in the knee

Answer:

A reflex arc is a neural pathway that controls a reflex. In vertebrates, most sensory neurons do not pass directly into the brain, but synapse in the spinal cord. This allows for faster reflex actions to occur by activating spinal motor neurons without the delay of routing signals through the brain.

It uses a reflex arc because a reflex controls the brain and makes you think quick to do a fast movement that is known as a reflex, a example is something falling and your instinct is to catch it.

Fungi and other decomposers feasst on dead matter and break them down. This increases soil fertility and allows more plants to grow.

Answer:

The role fungi plays is a decomposer.

Explanation:

Decomposers are plants that don't make their own food. They get their food from breaking down dead plants and animals. Usually you see fungi in forests because its more moist and has more greens.
