Explanation:
Radioactive dating technique
To confirm the ages obtained with magnetic records, and get an absolute age of the seafloor, scientists use the radioactive dating technique. When the lava solidifies at the ridges to form the new seafloor, radioactive elements coming from the mantle are trapped in it.

how can evolution lead to reproductive success?
Answers
Answer:
Evolution in humans is happening spontaneously and the development of species can improve the capability of offspring and the intelligence of species. All animals today are evolutionary, we came from bacteria to being are millions of times the size of that organism with millions of years going through evolution. We have gone from splitting our cells to make more, to creating life to another to do the same.

What order allows animals to get usable fuel from the sun? multiple chose
1.sun, consumer, producer
2.producer, consumer, sun
3.sun, producers, consumers
4.producers, sun, consumers
Answers
Answer:
3. Sun, producers, consumers
Explanation:
Energy from the sun shines upon a producer. The producer then photosynthesizes and converts the sun's energy into fuel for itself. If a consumer happens to eat the producer, it will absorb its energy.
Consumers eat producers, and producers use the sun to make food. Therefore, the easiest way for consumers to get fuel is through producers.
how does the respiratory and digestive system work together to maintain homeostasis
Answers
When groups of tissues work together, they are called organs. Some
examples of organs are the heart, lungs, skin, and stomach. When organs work together, they are called systems. For example, your heart, lungs, blood, and blood vessels work together. They make up the circulatory system.
There are eleven systems in the human body: muscular system, respiratory system, digestive system, integumentary system (skin), skeletal system, circulatory (or cardiovascular) system, excretory (or urinary) system, reproductive system, nervous system, lymphatic system, and endocrine system. Each system has a special job.
All of your body systems have to work together to keep you healthy. Your bones and muscles work together to support and move your body. Your respiratory system takes in oxygen from the air. It also gets rid of carbon dioxide.

Your digestive system absorbs water and nutrients from the food you eat.
Your circulatory system carries oxygen, water, and nutrients to cells throughout your body. Wastes from the cells are eliminated by your respiratory system, your excretory system, and your skin. Your nervous system controls all these activities with electrical impulses. If any system in your body isn't working properly, other systems are affected.
Think of your body as a building. A building has a plumbing system, a heating system, a cooling system, an electrical system, and a support system. If any system in a building breaks down, other systems can be affected.
As one example, think about a building's electrical system. Suppose a mouse chewed through an electrical wire to a furnace. Without electricity, the heating system would not work. If this happened in very cold weather, the plumbing system could be affected. Water pipes might freeze and burst. If a lot of water leaked into the building's walls, its support system would be damaged. Like a building's systems, your body's systems have to work together.
The respiratory system brings oxygen into the lungs when you breathe. The digestive system breaks food down into nutrients such as glucose. Now the circulatory system enters the picture. It transports glucose and other nutrients from the digestive system to the cells.
HOPE IT HLPS UH WELL✌✌DNA strands run in 1 of 2 directions depending on which end of the strand is free and which end has a phosphate bond. One direction is 5' to 3' (__________) and the other direction is 3' to 5' (downstream). __________ polymerase binds to the DNA at the TATA box and unzips the double helix. Working along the DNA chain, RNA polymerase reads the DNA nitrogenous bases and matches RNA nitrogenous bases from the nucleus (uracil instead of thymine). As it moves, RNA polymerase re-zips the DNA behind it and lets the mRNA separate from the DNA. It continues to do this until it reaches a sequence downstream called a __________ signal. In other words, RNA polymerase copies the DNA sequence downstream of the TATA box into an mRNA strand.

The answers in the blank spaces:
1. Upstream
2. RNA
3. Terminator
Explanation:
This question is describing the process of transcription, which is the process whereby DNA template is used to synthesize an mRNA molecule. Transcription involves three stages viz: initiation, elongation and termination.
- DNA strands run in 1 of 2 directions depending on which end of the strand is free and which end has a phosphate bond. One direction is 5' to 3' (UPSTREAM) and the other direction is 3' to 5' (downstream). An enzyme called RNA polymerase binds to the DNA at the TATA box and unzips the double helix (INITIATION).
- Working along the DNA chain, RNA polymerase reads the DNA nitrogenous bases and matches RNA nitrogenous bases from the nucleus (uracil instead of thymine). As it moves, RNA polymerase re-zips the DNA behind it and lets the mRNA separate from the DNA (ELONGATION).
- It continues to do this until it reaches a sequence downstream called a TERMINATOR signal (TERMINATION). In other words, RNA polymerase copies the DNA sequence downstream of the TATA box into an mRNA strand.

How will antibiotic resistance affect human populations if no action is
taken by our agricultural system?
Answers
Answer:
Explanation:
Antibiotic resistance is when the bacteria develop resistance to antibiotics. Antibiotic resistance will affect human populations is no action is taken by our Agricultural system because bacteria itself develop antibiotics resistance and these causes infections on humans and animals. The infections caused by antibiotics resistance bacteria are difficult to treat than those that are not caused by it. These the result in higher cost of medical treatment and treatment of animals, prolonged hospital admission and these can also lead to increased mortality or increase rate of death of Agricultural animals. When there is high mortality of Agricultural products due to this, there won't be enough consumption of these by humans and also there can be passage of these infections to human which can result to mortality.

Submit Answer
Answers
Answer:
1, uranus and neptune
Explanation:
i just did it
Based on the diagram above, the two planets having diameters that most closely resemble this comparison are: 1. Uranus and Neptune.
A solar system is an astronomical system which comprises both the inner and outer planets alongside celestial bodies such as a Moon, that are typically in orbit (traveling) around the Sun in slightly elliptical orbits..
Basically, the nine (9) planets that are found in the solar system orbiting around the sun include;
Mercury. Venus. Earth. Mars.Jupiter.Saturn.Uranus.Neptune.Pluto.Generally, the planets found in the solar system vary considerably in terms of shape and size as shown below:
1. Uranus and Neptune: the mean diameter of Uranus is 50,724 km (31,518.43 mi) while that of Neptune is 49,244 km (30598.8 mi).
2. Jupiter and Saturn: the mean diameter of Jupiter is 142,984 km (88,846 mi) while that of Saturn is 120,536 km (74897.6 mi).
3. Earth and Mars: the mean diameter of Earth is 12,756 km (7926 mi) while that of Mars is 6779 km (4212.275 mi).
4. Mercury and Venus: the mean diameter of Mercury is 4,879 km (3031.67 mi) while that of Venus is 12,104 km (7521 mi).
From the above data on diameter, we can deduce that both Uranus and Neptune are mostly related in terms of size as depicted in the diagram, by using two (2) circles of equal sizes.

4. Compare and Contrast Which kind of plant–a sun plant or a shade plant-has a
higher rate of photosynthesis when light intensity is below 200 umol photons/mº/s?
When light intensity is above 400 umol photons/mº/s?
Answers
Answer:
Below 200 umol photons/mº/s, shade plant grow best.
Above 400 umol photons/mº/s, sun plant grow best.
Explanation:
A shade plant has a higher rate of photosynthesis when light intensity is present below 200 umol photons/mº/s because shade plants needs low light intensity for higher photosynthesis while on the other hand, a sun plant has a higher rate of photosynthesis when light intensity is above 400 umol photons/mº/s because it requires high intensity of light for photosynthesis if other factors are also present in large amount such as water and nutrients in the soil.
