The role of a keystone species is..
A. To kill off invasive species in the area
B. To maintain biodiversity in the ecosystem through complex interactions with other animals in the area
C. To be able to make the environment safe
Answer:
The answer is B
Explanation:
A keystone species is an organism that helps define an entire ecosystem. Without its keystone species, the ecosystem would be dramatically different or cease to exist altogether. The ecosystem would be forced to radically change, allowing new and possibly invasive species to populate the habitat.

Alex is studying a population of fifty organisms that belong to the same species. Some of the organisms have dark spots, some have light spots, some have no spots, and some have stripes.
How does this species most likely reproduce?
Answer:
Sexual reproduction
Explanation:
There is a significant amount of genetic variation (diversity) here. Asexual reproduction results in little to no diversity, so we can assume this species reproduces sexually. Hope it helps :)

Explain how a single base mutation can encode a protein that has many missing amino acids.
Answer:
Silent mutation: Some mutations that change DNA bases do not have any effect on the sequence of amino acids in the protein. These mutations are called silent mutations and they do not affect the structure or function of the protein because there is no effect on the amino acid sequence.

Is the following sentence true or false? During meiosis, the two alleles for each gene stay together.
Answer:
False
Explanation:

What’s the answer please??!!!
Answer:
A
Explanation:
Almost all embryos of vertabrites look the same at early embryo stages, even humans to other organisms. This is because they all have a common ancestory, adn orginated from a organism with an embryo that looked like this.
It is clear it cannot be the other answers for the folowing reasons:
The organisms will definatly not look the same, considering they are birds and reptiles. The 2nd answer speaking of geography isnt very accurate, and cannot be determined because as I said above, any vertibrate embro looks very similar, and close geopgraphy isnt what made them look similar.
Again, all vertabrites have the same embryos, and that is a phylum. Not a genus. There are many genus in a phylum, and the ecaxt one cannot be determines.
As I said above, HUMANS look simiar to BIRDS and REPTILES, but clearly grow to be much different.
Answer:
A: the organisms share a common ancestory

Many organizations release indexes used to measure the development of the world's countries. As we learned in this lesson, these indexes measure many factors, from life expectancy to happiness. In your opinion, what are the three most important factors we can use to determine how developed a country might be? Explain your answers in a few sentences. << Read Less
Answer:
The correct answer is - GDP nominal, human resources and right, and GDP per capita.
Explanation:
The three major and most reliable factors about determining the development of a country out of all the indexes are GDP nominal, the human rights index, and the GDP per capita.
The economy and production of a country can be shown by the GDP nominal if it is showing progress or declines.
The Average income of the citizen of the country is exhibited by GDP per capita to examine if the wealth of the country shares that gives an idea about rich, poor or the middle class.
The human rights index defines the basics of life expectancy and the rights they have that decides the happiness.

what is the difference between an alligator and a crocodile
Snout Shape: Alligators have a wide, rounded, u-shaped snout, while crocodiles have long, pointed, v-shaped snouts. ... Crocodiles are different from alligators in this sense, where both upper and lower jaws of a crocodile are the same size, exposing their teeth as they interlock, creating the look of a toothy grin.
Alligators have U-shaped faces that are wide and short, while crocodiles have thin V-shaped muzzles. When an alligator closes its mouth, you tend to see only its upper teeth. Crocodiles on the other hand flash a toothy grin with their top and bottom teeth interlacing.
Which measure would be MOST effective in increasing the human population's immunity against contagious diseases?
A. Getting vaccinated against contagious diseases
B. Treating the first person infected with the contagious disease
C. Isolating the first person infected with the contagious disease
D. Distributing antibiotics in the community to avoid the contagious disease
The measure that would be most effective in increasing the human population's immunity against contagious diseases is getting vaccinated against contagious diseases, which is option A.
What are contagious diseases?The most effective measure for increasing the human population's immunity against contagious diseases is getting vaccinated against them. Vaccines are designed to stimulate the immune system to produce a response against specific diseases without causing the disease itself. When people get vaccinated, their immune systems are able to recognize and fight off the disease if they come into contact with it in the future. Vaccination is a safe and effective way to prevent the spread of contagious diseases and protect individuals and the community as a whole.
Hence, the measure that would be most effective in increasing the human population's immunity against contagious diseases is getting vaccinated against contagious diseases, which is option A.

This is the original strand of DNA: ATG AAG TTT GGC TAA
Which option would represent a frame shift mutation due to deletion during replication?
Answer:
ATG AAG TTG GCT AA
Explanation:
I took the test
A genetic modification in which there is an acquisition and omission of nucleotide base in the series is called frame-shift mutation.
It modifies the reading frame of the series that can vary the amino acid sequences and the protein that it forms.
The correct answer is:
ATG AAG TTG GCT AA
This can be explained as:
In the sequence given in the question ATG AAG TTT GGC TAA there is a deletion mutation in the Thymine (T) nucleotide.The deletion of thymine (T) causes the reading frame of the three-nucleotide to change and the reading pattern gets altered.The frame now changes and the reading will start with altered three base pairs.So, the sequence ATG AAG TTT GGC TAA will be mutated to ATG AAG TTG GCT AA.
