Explanation:
biologists knew that South America and Africa contained similar fossils. These fossils led them to believe that a temporary land bridge between South America and Africa allowed ancient species move between both continents. In the twentieth century, evidence showed that South America and Africa were once part of the same larger continent and that there were no land bridges between them How should ologists respond to the new geological finding? 0 Biologists should reject the geological finding, because it is new. Biologists should ask physicists what to do, because physics is a more exact science Biologists should reject the belief in ancient species, because there were no land bridges. Biologists should update the history of life, because it should include the new geological finding Next 3:12 PM 2/10/2021 2 ^ Previous o B Type here to search

African elephants once existed in large populations across the African continent. Elephants use their tusks to dig for water and food. Humans hunt and kill elephants for their tusks. Habitat loss and fragmentation have also reduced the total number of elephants and the size of elephant herds. Scientists estimate that the number of African elephants has decreased from several million to several hundred thousand. Population sizes range from over 100,000 individuals in Botswana to approximately 100 individuals in northern Cameroon. Scientists have also found that the frequency of elephants that never develop tusks is increasing.
Select all the statements that describe probable effects of poaching and habitat fragmentation on clephant evolution
a. The elephant population in Botswana will experience high levels of genetic drift.
b. The poaching of elephants for their tusks is leading to the evolution of tuskless elephants.
c. Having tusks does not provide a selective advantage to African elephants.
d. Habitat fragmentation leads to decreases in population size and increases in genetic drift.
e. The elephant population in Cameroon will experience high levels of genetic drift.
Answer:
Option D
Explanation:
In habitat fragmentation, a large ecosystem or habitat of any species is converted into small ecosystems in such a way that each small ecosystem remains isolated from each other. Being isolated , random genetic drift comes in picture and reduces the gene flow with in the isolated habitats.
Hence, option D is correct

Answer:
Oculus
Explanation:
The organ of vision that consists of the eyeball and the optic nerve. Synonym(s): oculus [TA] .
Answer:
Medical Terminology Ophthalm/o = Eye Ophthalm/o = Eye Ophthalm/o = Eye Opt/o = Vision.
Light passes through the front of the eye (cornea) to the lens. The cornea and the lens help to focus the light rays onto the back of the eye (retina). The cells in the retina absorb and convert the light to electrochemical impulses which are transferred along the optic nerve and then to the brain.

The RNA that is translated into a polypeptide is ______ RNA
Answer:
The RNA that is translated into a polypeptide is messenger RNA
Explanation:
Brainliest please! :)
The RNA that is translated into a polypeptide would be the messenger RNA.
For translation to occur, genetic information on DNA is first transcribed to messenger RNA in the nucleus in a process known as transcription. The pre-mRNA then undergo some modifications before being transported to the cytoplasm where it gets translated into protein.
The mRNA binds to the ribosome and another RNA, the transfer RNA, binds with its anticodons. The genetic codes on the mRNA are read in 3s and the respective amino acids corresponding to the anticodons on the tRNA are released. The amino acids are then linked together by peptide bonds.

Explain how cellular respiration and photosynthesis make a system together.
Answer:
cellular respiration in photosynthesis are biological processes in which matter and energy flow through the biosphere. These two processes are responsible for the exchange of oxygen and carbon dioxide between living organisms and the environment. Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a byproduct. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by-products and ATP is energy that is transformed from the process.
Almost immediately after injection, you find yourself swept into a good-sized chamber, the _(1)_. However, you do not stop in this chamber, but continue to plunge downward into a larger chamber below. You land with a large splash and examine your surroundings.

You report that you are sitting in the _(2)_ chamber of the heart, seeing the flaps of the _(3)_ valve above you. The valve is open and its anchoring cords, the _(4)_, are lax. Since this valve is open, you conclude that the heart is in the _(5)_ phase of the cardiac cycle.
Answer:
Almost immediately after injection, you find yourself swept into a good-sized chamber, the left atrium. However, you do not stop in this chamber, but continue to plunge downward into a larger chamber below. You land with a large splash and examine your surroundings. All about you are huge white cords, hanging limply from two flaps of endothelial tissue far above you. You report that you are sitting in the left ventricle chamber of the heart, seeing the flaps of the mitral valve above you. The valve is open and its anchoring cords, the chordae tendineae, are lax. Since this valve is open, you conclude that the heart is in the systole/contraction phase of the cardiac cycle.
Explanation:
Once the oxygenated blood enters the heart through the pulmonary vein, it goes to the left atrium. From there, it goes down to the left ventricle passing through the mitral valve, also known as the bicuspid valve. This valve prevents blood's backflow when the heart contracts, allowing the blood's flow from the ventricle to the aorta.
The chordae tendineae, also known as tendinous cords, are in the mitral and the tricuspid valve. They are cords that are attached to the valve and the heart walls. They are lax during atrial systole, and with the help of blood pressure, they allow the valve to open and welcome the blood into the left ventricle. The tendinous cords are tense during ventricle systole preventing the valve from opening and causing a backflow from the ventricle to the atrium.
Which of the following flows through ecosystems in one direction?
A.water
B.energy
C.carbon
D.nitrogen
Answer:
B energy
Explanation:
because I just know D.
The energy flows through ecosystems in one direction. so the correct option is B. Firstly the energy flows from the sun to autotrophs, or producers. Then it further flows from producers to consumers. Energy never flows backward from consumers to producers.
What is ecosystem?An ecosystem is refers to as a geographic area in which plants, animals, and other organisms, as well as weather and landscapes, work closely to form a bubble of life.
On average only about 10% of energy stored as biomass in a trophic level and is passed from one level to the next. This is called as the 10 percent rule and it limits the number of trophic levels an ecosystem can support.

Hello, I would really appreciate it if you guys could help me answer this, please answer one of the boxes in your own words, I'm in a rush because it will be due tonight.
Answer:
The definition of kinetic energy (also called energy of movement) is a form of energy that an object has which involves motion, and it's a property of a moving object and depends not only on motion but also on mass.
The definition of thermal energy (also heat energy) would be: the energy that's inside of a system that has sole control over its temp.
