WHICH STATEMENT IS the strongest evidence in support of endosymbiotic theory of eukaryote evolution
Answer:
Please see my answer below.
If you like my response you can mark it as brainliest.
If you have any doubts (no joke) you can reach out to me in the comments.
Explanation:
The endosymbiotic theory states that some of the organelles in eukaryotic cells were once prokaryotic microbes. Mitochondria and chloroplasts are the same size as prokaryotic cells and divide by binary fission. Mitochondria and chloroplasts have their own DNA which is circular, not linear.
Which statement best describes why the body tries to maintain homeostasis?
- The body must maintain homeostasis so that the internal environment matches the
outside environment
- The body must maintain homeostasis so that the internal environment stays the same if the outside environment changes.
- The body must maintain homeostasis to make sure that a person’s heart and respiration rates are the same.
****Its the second one, (just took test) im just posting for other peeps****

In 1915, the scientist Thomas Hunt Morgan discovered that certain genes on chromosomes are associated with specific traits in fruit flies. However, the mechanism through which this process occurs was not detailed until 1966. That is when Marshall Nirenberg and several other scientists demonstrated that specific sequences of nucleotides in DNA correspond to specific proteins. After gene sequencing was introduced in 1977, scientists were able to use Nirenberg's discoveries to predict an organism's proteins from its DNA sequences.
How does the information above illustrate the nature of science?
A.
It shows that scientific progress is made primarily through observational rather than experimental evidence.
B.
It shows that earlier scientific ideas are typically incorrect since genes code for proteins and not traits.
C.
It shows that scientific ideas are durable but are developed as new data are collected.
D.
It shows that scientists like Nirenberg did not rely on ideas of others in making major discoveries.

movement through the cell cycle is not controlled in the cells?
True or False
Answer:
False is the correct answer
Cell-cycle control is entirely dependent on post-transcriptional mechanisms such as phosphorylation of Cdk activity and the binding of regulatory proteins such as cyclins, which are themselves regulated by proteolysis.
movement through the cell cycle is not controlled in the cells is True.
What regulates the movement of a cell through the cell cycle?In addition to this structural function, the cytoskeleton is in charge of cell movement. Internal transport of organelles and other structures (such as mitotic chromosomes) through the cytoplasm is one of these.Cell-cycle control is entirely dependent on post-transcriptional mechanisms such as phosphorylation of Cdk activity and the binding of regulatory proteins such as cyclins, which are themselves regulated by proteolysis.Disruption of normal cell cycle regulation can result in diseases such as cancer. When the cell cycle is uncontrolled, cells can divide haphazardly and accumulate genetic errors, which can result in a cancerous tumor.To learn more about : Cell cycle

Electronegativity increases when atoms
A. are located on the right on the periodic table
B. are located on the left on the periodic table
c. have a large atomic radius
D. have a small atomic radius
Answer:
A. and D.
Explanation:
If we go horizontally, from the left to the right on the periodic table, the electronegativity increases.
If the radius is small, that means the electrons are closer to the nucleus, which makes them more electronegative.

According to the gate control theory, what is one reason we are able to block the perception of pain?
Answer:
Gate theory claims that pain sensations must pass through a space, or gate, in the spinal cord, which can be closed to block pain signals sent from the brain or peripheral receptors.
Explanation:
According to the gate control theory, the activities of large fibres cause the excitation of inhibitory neurons. This reduces the transmission of pain signals.
What is gate control theory?
This is a type of defence mechanism by our nervous system. In this mechanism, the signals that are sent to the brain, by the spinal cord for the perception of pain, are managed by the spinal cord itself.
This may include the mechanism of reducing or increasing the pain. Therefore, the gate theory can heighten or decrease the perception of pain meaning the gate can either be closed or it can be open. The pain signals will pass to the brain if the gate is open and they will be restricted to the spinal cord if the gate is closed.
A painful or noxious stimulus of pain can be restricted or managed by a non-noxious stimulus. Like a backache can be managed by a gentle back massage.
Therefore, a gate control mechanism helps in blocking the perception of pain in the spinal cord.

Write a “lifeline” of a robin over the first year of its life. Include important events.
Explanation:
Robins are born in the spring or summer and are mature birds and ready to breed in the following spring or summer. They do not mate for life. Pairs usually remain together during an entire breeding season, which can involve two or three nestings. However, in spring, sometimes a male and female who mated the previous year will both return to the same territory and end up together for another year. This happens most frequently when they were successful raising babies the previous year. Robins lay one egg per day, for a total of 5–6 eggs in a clutch. The eggs hatch about 12 - 14 days after the last egg was laid. Baby robins jump from their nest when they are about 13 days old, but the range is 9 - 16 days. After leaving the nest (fledging), it takes another 10-15 days for babies to become strong fliers and independent birds. The parents continue to feed their young during this period.
Most robins die their first year. But the lifespan goes up dramatically for the ones that survive this critical time, because they've learned so many important life skills. Of those that survive their first year, most wild robins live to be about 5 or 6. As of February, 2001, the longest-living banded wild robin ever recorded had survived 13 years and 11 months, according to the Bird Banding Laboratory at the Patuxent Wildlife Research Center. In captivity, robins have survived longer than 17 years.
Answer:
In the spring, robins travel north and mate. Much chirping and singing go on among the robins before they mate. The eggs are fertilized inside the female's body. Newborn robins are nearly helpless. Their eyes are closed. They cannot feed themselves, so their parents get insects and bring them to the young. When another animal or bird gets near the nest, the parents protect the young robins. After the little robins grow enough to survive on their own, they are pushed from the nest by the parents.

The biological levels of organization of living things arranged from the simplest to most complex are: organelle, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystem, and biosphere.
Explanation:
The major levels of organization in the body, from the simplest to the most complex are: cells, tissues, organs, organ systems, and the human organism.
What is the simplest level of body organization?The human body is made up of atoms, cells, tissues, organs, and organ systems. The chemical level, which is the simplest, is made up of atoms. Cells are the smallest units of life that can do work.
Similar cells form tissues. The main types of tissues are epithelial, muscular, connective, and nerve.
Organs are structures made up of at least two types of tissue that do specific jobs in the body. The liver, the stomach, the brain, and the blood all do different things. Organs help the body perform functions.
Then come the organ systems. A system of organs is a group of organs that work together.
