what system allows you to walk, talk and breathe.
The body system that allows a person to walk, talk, and breathe is the respiratory system. The respiratory system is composed of the airway, the lungs, and the muscles of the respiration. The respiratory system allows a person to taken in the air allowing him to breathe in the oxygen, and breathe out the carbon-dioxide. The ability to speak is also dependent on the breathing in of the air. The person can walk, or run, as a thanks to his respiratory system, which is constantly inhaling oxygen to provide him the energy.
Hence, the answer is 'respiratory system'.

Explain how bone marrow can be called tissue
Final answer:
Bone marrow is considered a tissue because it is a connective tissue with specialized functions—the yellow marrow stores energy, and the red marrow is responsible for hematopoiesis, the production of blood cells.
Explanation:
Bone marrow is referred to as a tissue because it is a connective tissue that fills the interior of bones. There are two types of bone marrow: yellow marrow and red marrow. Yellow marrow is rich in adipose tissue and stores energy in the form of triglycerides within adipocytes. Red marrow plays a crucial role in hematopoiesis, the production of blood cells, including red blood cells, white blood cells, and platelets. This process involves the proliferation of stem cells, which are self-renewing and differentiate into various blood cell types. Bone marrow functions as a vital component within bones, which are considered organs containing multiple types of tissues such as blood, connective tissue, nerves, and bone tissue. Osteocytes within bone tissues create the mineral matrix that characterizes bones.
What is a spring tide abs would a spring tide occur
A spring tide occurs during the new and full moon phases when the Sun and Moon align, leading to the highest and lowest tides of the month. This contrast creates the greatest tidal range.
A spring tide occurs when the gravitational forces of the Sun and Moon align either on the same side of Earth or on opposite sides.
This alignment happens during the new moon and full moon phases, where the combined gravitational pull results in the highest high tides and the lowest low tides of the month, leading to the greatest tidal range.Conversely, a neap tide occurs when the Sun and Moon are at right angles to each other, during the first and third quarters of the moon. During this period, their gravitational forces partially offset each other, leading to the smallest tidal ranges of the month.Describe the importance of mitosis in the root tips of plants
The importance of mitosis in the root tip is that it helps the growth of the root; as a result, the root can grow more and absorb more nutrients from the soil, which helps the plant grow further.
What is the role of mitosis?Mitosis is a process in which the cell divides equally and both the parent cell and the daughter cell look alike. In this process, the plant root grows during mitosis, the old cell is replaced by the new cell, the cut is filled, and so on.
The mitosis completes in five steps, such as the prophase, metaphase, anaphase, telophase, and cytokinesis, where the cell faces many changes, such as the nuclear envelope dissociating and the cytoplasm of the cell dividing. The mitosis is the result of the body size growth that is seen in the child, and this is the result of the mitogens.
Hence, the importance of mitosis in the root tip is that it helps the growth of the root; as a result, the root can grow more and absorb more nutrients from the soil.

The butterflies shown below all belong to the same species, but one of them has inherited a rare mutation for blue wings rather than orange wings. The butterflies feed on nectar from orange flowers, and their color acts as camouflage while they feed.
What will most likely happen to the butterfly with blue wings?
Their population will decrease while that of orange-winged butterflies will increase. Therefore the allelic frequency for blue colored wings will be eventually eliminated from the population.
This is because the blue-winged butterflies will be predated more because they are more conspicuous. Most will not produce before they are predated on hence reducing their numbers. The next generations will have more and more of orange-winged butterflies until the blue-winged butterflies no longer exist in the population.
Answer:
It will be less likely to survive because it will be more visible to predators.

Explanation:
What feature would you expect to find in a population in which sexual selection depends on female choice?
Where sexual selection is based on male competitiveness, bright-colored males are expected to be seen.
What distinguishes sexual selection?Sexual selection theory holds that the emergence of some noticeable physical qualities in animals, such as pronounced colour, increased size, or spectacular adornments, may provide the possessors of these traits more success in attracting mates.
Because the number of gene copies in the next generation is also dependent on relative mating success, the strength of sexual selection is proportional to the relative increase in the number of offspring surviving to reproduce (Sn) and the relative number of mates a male with that character obtains.

Answer:
The correct answer is 60 percent.
Explanation:
The Clean Water Act refers to a federal law of United States, which observes the release of contaminants into the surface waters of the country, comprising rivers, lakes, wetlands, streams, and coastal areas. Approximately 30 years after passing of the Clean Water Act in the United States, the percentage of surface water, that is, regarded safe for swimming and fishing had enhanced from 36 percent to 60 percent, which is approximate twice the original value. Some kind of policies and programs were implemented as part of the act.
which of following is something almost everyone can do to reduce his or her carbon footprint? A.Heat the house more in the winter B.Turn up the water heater C.Use a fan instead of air conditioning D.Drive the car more often
The correct answer is option C, that is, use a fan instead of air conditioning.
The greenhouse gases like methane, carbon dioxide, and ozone contribute to ozone depletion, pollution, and global warming. The carbon footprint of humans signifies towards the net amount of greenhouse gases generated by them or by the things used by them, of the things fossil fuels being a prime contributor.
The things like heating, driving a car, and cooling, and using electrical power from coal and gas discharge carbon dioxide, and enhances the concentration of greenhouse gases in the atmosphere.
In order to reduce carbon footprint, one can use a fan in place of the air conditioner, as ACs emits chlorofluorocarbons, which can further aggravate the situation of greenhouse gases and can donate more to ozone layer depletion.

which statement best describes how a muscle moves a bone
Muscles move bones by contracting and pulling on tendons attached to the bones, which causes the bones to move like levers with joints serving as fulcrums.
Explanation:The statement that best describes how a muscle moves a bone is that skeletal muscles contract, which pulls on tendons that are connected to bones, causing movement. Muscles work across a joint and are attached to both sides of a joint by tendons, which are strong cords of connective tissue. When these muscles contract, they shorten and pull on bones, making them move like levers with joints acting as fulcrums. This is how the muscles facilitate movement in the body by applying force to the skeleton.

1. Describe how radio telescopes are used to explore space.
Radio telescope picks up the radio spectrum of electromagnetic waves from celestial bodies (just like telescopes like the Hubble pick up visible light – only that radio waves are invisible to our eyes). They are therefore used to detect objects in space that produces radio waves. Examples are quasars and pulsars. Radio telescopes also enable astronomers to be whats beyond gas and dust in space that blocks out most of the visible light spectrum.
Answer:
Radio waves from space are sensed by a giant parabolic reflector which concentrates them toward the top of a focusing antenna. A radio receptor converts the radio waves into electrical signals which are amplified and then transmitted to the center of the parabola. They are then recorded and analyzed in the laboratory so that scientists can obtain a radio image of the source observed. The parabolic antenna can usually be oriented to detect radio waves from all directions of space.
