(BRAINLIEST FOR CORRECT FAST ANSWER!!!) Look at each of the thirteen primates and determine the following. Which is the largest? Which is the smallest? How many have tails? Which ones have the largest eyes relative to body size?
The gibbon is not a monkey. They are considered lesser apes since they are smaller than great apes yet are members of the ape family.
What similarities primates share among together?Although the anatomy of the noses of lemurs and tarsiers are similar, lemurs have a material behind their irises that reflects light, whereas tarsiers don't.
Primates share genetic traits since they are linked to one another. In general, chimpanzees and bonobos, who are the closest living cousins of humans, share roughly 99% of human DNA with our most distant ape ancestors.
Baboons always live on the ground, unlike monkeys, which can either be terrestrial or arboreal. Not all monkeys have a long muzzle like a dog, only baboons do.
Therefore, The same characteristics apply to monkeys. Tarsier skulls have similar olfactory and visual characteristics to monkey skulls.

Muscle cells Nerve cells Skin cells Blood-producing cells Digestive tract cells Cells that do not divide once they have developed
Cells that grow and divide throughout life
Answer:
Explanation:A few types of differentiated cells never divide again, but most cells are able to resume ... life to replace cells that have a high rate of turnover in adult animals. Cell proliferation is thus carefully balanced with cell death to maintain a constant ... Cells of this type include skin fibroblasts, smooth muscle cells, the endothelial cells ...
The cells that do not grow or differentiate once they are developed are usually in the internal structures.
Muscle cells
Nerve cells
Digestive tract cells these cells once developed do not divide once they have been developed.

So, what is actually produced during the light reaction? Do you know the chemical
equation?
Answer:
The light-dependent reactions convert light energy into chemical energy, producing ATP and NADPH. 5. The light-dependent reactions can be summarized as follows: 12 H2O + 12 NADP+ + 18 ADP + 18 Pi + light and chlorophyll yields 6 O2 + 12 NADPH + 18 ATP.
Water is oxidized, electrons are transported from water to NADP+, and ATP is generated during the light processes.
What is light reaction?The light reactions are the first step in photosynthesis. The pigment chlorophyll in the thylakoid membranes of the chloroplast absorbs the energy from sunlight during these reactions. The energy is subsequently briefly transferred to two molecules, ATP and NADPH, which are used in photosynthesis' second stage. Two electron transport networks produce ATP and NADPH. Water is used in the light processes, and oxygen is created. Because the process requires sunlight to begin, these reactions can only take place during daylight hours.the reaction is provided in the image below:

What might an elevated skin temperature indicate beside a fever from a cold, flu, or other typical viral disease? How might you test for an elevated temperature?
Answer: Fever is a common symptom of illness. The Centers for Disease Control and Prevention (CDC) defines fever as a temperature above 100.4° F, though children often run higher fevers than adults.
Many types of infection can cause fever, as your body will increase temperature to effectively fight off the virus or bacteria causing the infection. These fevers will usually resolve themselves as your body works to get rid of the foreign invader.
Explanation:
Fever is one of the common symptoms of different illnesses and is also a defense mechanism of the body. A temperature above 100.4° F is considered as fever.
Fever can be caused due to:
1. The rise in the skin temperature is generally due to the infection from bacteria or viruses that can result in the flu, cold, or certain viral diseases. The fever can be an indication of any infection or inflammation in any part of the body.
2. The activities like exercising can also lead to an increase the body temperature. The contraction of muscles releases 20% energy and the rest 80% is converted into heat energy. The heat is then circulated to different parts of the body, causing an increase in the temperature.
3. The rise in the temperature can be measured by the thermometer. It is a device that measures body temperature either digitally or traditionally.
Thus, the cause of fever can be a defense mechanism, exercise, and infection from the pathogen.

answers to Video 1 and 2 don't copy word for word
Explanation:
Video 1 questions:
1.Viking 1 and Viking 2 transmitted six years of panoramic views from Mars to Earth, while the pathfinder spent three months transmitting large quantities of Martian environment data. For study, the Viking 1 and 2 probes sent photographs of the Martian landscape back to Earth, while the pathfinder was the first robotic rover to reach the Martian atmosphere directly.
2.It contributed to the discovery that life on Mars once actually existed because of evidence of water being found underground at the Martian poles.
3.it helped us to discover that life on Mars once probably existed because of signs of water being found underground at the Martian poles.
4.Spectrometric equipment that could analyze Mars' atmosphere was needed by Mars Odyssey and Mars Express.
5.A probe is a spacecraft that flies across space to gain information about science. Probes have no astronauts. Probes submit data back to earth for analysis by scientists. Voyager 2 and many more are one example of a space probe.

1.Radio waves are a type of electromagnetic radiation that is best recognized for its use in Technologies for contact, such as television, cell phones and radios. Such devices receive radio transmitters In the speaker, waves and transform them to mechanical vibrations to produce sound waves.
2.A radio telescope is essentially a telescope equipped to receive space-based radio waves.
3.It has three numerical elements, each of which has one or more antennas to absorb the incoming radio waves. Two is a receiver and amplifier to lift to a detectable level the very weak radio signal. And lastly, a recorder to hold a signal log.
4. An electromagnetic wave is a radio wave. The speed of light flows with it. In the electromagnetic spectrum, it is the longest wavelength. This is used in RADAR for wireless and radio communication that is obtained by an antenna, and radio waves are also used. RADAR is a method of tracking used to determine object velocity.
5.Through studying the frequency, power, and timing of radio emissions from these objects, radio telescopes help advance our knowledge of the universe, and astronomers will enhance our understanding of the universe.
Answer:
1. Viking 1 and Viking 2 probes transmitted panoramic views of the red and rocky soils back to Earth after six years later. The Pathfinder probe sent back large amounts of data of the environment especially about climatic variations in only three months. You can tell the technology was very different between these two because of how long it took for each probe to gather data.
2. In 1965, Mariner 4 and 9 probes found geological formations (Olympus Mans). The Mariner 4 sent back the first image of Mars. The Mariner 9 found erosion marks that indicated that there was once water on Mars. In 1976, the Viking 1 and 2 probes transmitted panoramic views of the soils. From 1965 to 1976, they were able to discover more about Mars over improving the technology. When the Viking probes were launched, we discovered more than when the Mariner probes were launched. For example, we were able to uncover how red and rocky the soils were.
3. We now receive information differently thanks to wireless technology. For instance, we now have computers and phones that let us contact someone by simply pressing a button. GPS may now be used to display various places. Additionally, we can now forecast the weather. We can know the weather for every day because forecasters have access to a ton of technology. Thus, we now substitute archaic methods for digital ones.
4. Fire alarm and air conditioning systems include technologies that incorporate various communication systems that enable them to react to changes in the atmosphere or temperature. Therefore, when the atmosphere's temperature fluctuates, they are utilized.
5. Viking 1 and 2 were used to find life on Mars. Since they launched the Mainer probes, they found that there was once water on Mars which later created the Viking 1 and 2 probes for further investigation. Along with finding life on Mars, they were also created to take better photos of the planet.

Based on his experiments on pea plants, how many factors did Mendel conclude an offspring receives for a single characteristic?
Answer:
The answer is 2
Explanation:
Based on his experiments on pea plants, Gregor Mendel concluded that an offspring receives two factors / genes for a single characteristic. These factors exist in pairs, with one factor inherited from each parent. So, here option A is correct.
Mendel's experiments involved cross-breeding different varieties of pea plants and carefully tracking the inheritance patterns of specific traits, such as flower color, seed texture, and plant height. Through his observations, he formulated the fundamental principles of inheritance, which laid the foundation for modern genetics. Mendel's conclusion was based on his observation of the consistent segregation of traits in the offspring. He found that when two pea plants with different forms of a trait (such as tall and short plants) were crossed, the first generation of offspring (F1 generation) all displayed the dominant form of the trait (in this case, all tall plants).
