Answer: Answer is explained below.

Explanation:

Solar system formation put in order:

  • A solar nebula forms.
  • Gravity pulls the solar nebula upon itself.
  • The solar nebula spinsfaster and faster.
  • The solar nebula flattens into a disk.
  • Gas becomes hot and dense and forms a star.

Using random sampling technique, select 3 grid segments for a sample taken from the plot above. List the 3 grid segments you selected. (1 point)

Answers

Answer:

I don't know exactly what you need but I give you an example so that you can create your samples through the Excel program, I hope it helps.

Just enter your sampling frame (the clients of which you have contact information) in the spreadsheet. Once you have a sampling frame (possible respondents) in Excel, you can easily select a random sample among them. For example, in your case that it is a work of biology and neceists three random samples here you can apply it with the following rules:

-Add a new column in the spreadsheet and name it "Random Number".

-In the first cell below your header row, type "= RAND ()".

-Press “Enter” and a random number will appear in the cell.

-Copy and paste the first cell in the other cells of the column.

-Once each row has a random number, organize the records from the "Random number" column.

-Then, select the first samples. In this way you will randomly choose from all samples.

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. In this situation what is natural selection selecting for? In this situation what is natural selection selecting against? How do you predict this population will evolve? Identify how each of the listed conditions from the above scenario that influence natural selection.

Answers

Explanation:

Natural selection is the mechanism that is responsible for the evolution of organisms.  

In the given case, the Freshwater shrimp has been introduced to a pond in which the two species with variations are introduced.  

The C. cantonensis is brighter in color whereas the C. multidentata is mottled drab in color. The predator fish can feed easily on the species which is brighter therefore C. cantonensis is more susceptible. The mottled drab species is not easily predated by the species.  

The 30 % offsprings of C. cantonensis can survive till the reproductive age  whereas 75% of C. multidentata. This shows that natural selection has acted on the color of the shrimp species selected against the predator fish species.

The species with mottled drab color is the result of the differential reproductive rate.

Final answer:

Natural selection is favoring the Caridina multidentata species due to its mottled coloration providing protection against predators, and acting against the Caridina cantonensis species due to its conspicuous coloring. Higher survival rates to reproductive age in Caridina multidentata suggest that, over time, this species will increase in population assuming other environmental factors remain constant.

Explanation:

In the given scenario, natural selection is favoring the Caridina multidentata species. The mottled and drab coloration is providing higher survival rates by offering protection against predation. On the other hand, natural selection is acting against the Caridina cantonensis species which has bright colors that make it easily detectable by predators, leading to its lower survival rates.

The given conditions of coloration and survival rates to reproductive age influence natural selection. The higher survival to reproductive age in Caridina multidentata ensures the transmission of its color characteristics to a larger number of offspring. This leads to the prediction that over time, the population of Caridina multidentata will tend to increase compared to Caridina cantonensis, assuming all other environmental factors remain constant.

#SPJ12

In guinea pigs, a single gene with two alleles (B and b) determines coat color. Black (B) is dominant over white (b). A guinea pig from a true-breeding black strain is mated with a guinea pig from a true-breeding white strain. The F1 progeny are all black. Two of the F1 progeny are mated with each other. What proportion of the black F2 progeny is expected to be heterozygous?

Answers

Answer: Half of the black F2 progeny is expected to be heterozygous.

Explanation: I used a Punnett square to predict the next generations’ alleles.

On April 26, 1986, Reactor 4 at the Chernobyl Nuclear Power Station in Ukraine exploded, releasing radioactive isotopes into the air. The majority of the isotopes that were released and spreading thousands of miles were of the element iodine. As a class, discuss what endocrine glands would be most affected and how it would become apparent in the nearby population.

Answers

The thyroid gland will be mostly affected in this case. The element Iodine is

the major precursor which is involved in the formation of two hormones.

Thyroid hormones

  • Triiodothyronine (T3)
  • Thyroxine (T4).

When an individual is exposed to radioactive iodine , it alters the production

of the hormones which leads to series of effects such as:

  • Decreased metabolism
  • Low body weight
  • Goitre etc.

Answer:

In the given case, the thyroid gland will be affected the most due to the exposure of the element iodine. For the synthesis of thyroid gland hormone, T3 and T4 iodine is required. As the exposure of the radioactive iodine element is taking place, therefore, it will result in the deterioration of the thyroid gland. Radioactive iodine is generally used in the treatment of hyperthyroidism.  

However, in normal individuals, the exposure of the radioactive iodine element results in a decrease in the level of thyroid hormones below the normal level due to the destruction of the thyroid cells. The symptoms seen can be neck tenderness, swollen salivary gland, and loss in body weight.

NEED HELP QUICK!!!1). The Miconia plant is not a native plant to Hawaii. Since its introduction into Hawaii 40 years ago, it has become a popular decorative plant. However, this shallow-rooted plant has replaced many of the native deep-rooted plant species and increased the likelihood of landslides on the island. Which is one of the BEST methods of dealing with this invasive plant?A) The plant should be shared with the smaller islands.B) The plant should be fed to the native livestock on the island.C) The plant should be uprooted from all regions in the island.D) The plant should be cross-bred with deeper-rooted plants.2). In the Everglades, a system of canals and levees diverts water to urban areas and the Everglades National Park. This water management system has caused changes in the natural flow of the water during the wet and dry season. Wading birds are especially sensitive to wet and dry seasonal changes. How have water cycle disruptions MOST likely affected wading birds?A) The reduced salinity results in more eggs being laid.B) The water quality for feeding has been improved by runoff.C) The release of water dilutes food sources for their young.D) The higher water levels allow longer-legged birds to survive and reproduce.3). In Florida, humans have caused more than 2,000 manatee deaths since 1974. Collisions with boats and boat propellers cause roughly twenty-five percent of all manatee deaths. Another significant cause of the declining population is the disappearance of manatee habitats, resulting primarily from coastal development, water quality problems, and the change in water levels caused by Florida’s flood control systems. A constitutional amendment has been proposed that would protect natural systems and biological diversity. Which would be the MOST likely requirement of a constitutional amendment to protect the manatee population?A) moving manatees to locations outside of the EvergladesB) restricting manatee hunting in the Everglades to certain times of yearC) raising more manatees in captivityD) placing a limit on speedboat use in manatee habitats
