Answer:

Courtship can be defined as the behavior used to obtain copulation with a partner, or to maintain reproductive interactions with an existing partner.Courtship, in animals, behaviour that results in mating and eventual reproduction. Courtship may be rather simple, involving a small number of chemical, visual, or auditory stimuli; or it may be a highly complex series of acts by two or more individuals, using several modes of communication.It help strengthen a pair bond that may last through the raising of the young or even longer.Courtship is its use as an isolating mechanism, a method of keeping different species from interbreeding.

Answer:

to ensure that the two individuals are of the same species

Explanation:

It also involves stereotyped behaviours. Courtship behaviour informs a potential mate that the intention is breeding and not aggression.

1. A person who is interested in how athletic activity affects the body might pursue a career in 1. endocrinology 2. gene therap

Brut [27]

Answer:

1. sports medicine

2. gene therapy

3. Adrenal gland

4. false

5. Hormones

6. To regulate body activities (like growth and immunity) by sending chemical messages

Explanation:

1. Sports medicine is the branch of medicine that is related to physical fitness, so if the question ask for someone who is interested in athletic activity, the correct answer is number 4.

2. Gene therapy is an experimental technique that in order to treat or even to prevent disease genes are used to help with their treatment, so a person who is interested in genetics and its relation with health, the correct answer is number 2.

3. Adrenal gland this is the gland that sintetice Adrenaline also known as epinephrine which is a hormone or also a medicine that plays an important role in the fight or flight response, this hormone is the one in charge of giving us several symptom like tachycardia or dilated pupils in order to survive in dangerous situations, so the correct answer to Sarah's problem is number 1.

4. False the endocrine system serves as a messenger to regulate hormone synthesis and are secreted to the circulatory system.

5. Hormones, as we have answer before hormones are regulated by the endocrine system.

6. To regulate body activities (like growth and immunity) by sending chemical messages hormones play an important part in human development and growth, these chemical messages serve to regulate the synthesis (creation) and secretion (liberation) of the hormones in the specific quantity as the body needs them.

Troyanec [42]

Answer: b. False

Explanation: It is the other way round when it comes to the definition of these terms.

Kinematics is the study of the motion of objects or points with its basic reference to factors such time, velocity, acceleration, distance, angle and so on. It is also known as the Geometry of Motion.

Kinetics is the study of the forces that are involved in the motion of an object. It deals basically with the cause and effect of that object.

Basically derived from Newton's Laws of Motion.

Which type of mining is likely the least harmful to the environment? a. Surface mining b. Placer mining c. Subsurface mining d.

Roman55 [17]

There are different types of mining activities that depend on the extraction magnitude, the size and deepness of the mineral deposit, and its costs. The least harmful to the environment is Subsurface mining. Option C.

--------------------------

There exist different types of mines depending on the extraction magnitude and methods.

The method used to extract minerals depends on the mineral deposit, the deposit size and deepness, and the work costs.

The environmental and health problems that mining activities produce involve the extraction process, transport of material, mineral processing, and the residues and wastes left at the extraction site that remain there for too much time and disperse to other areas polluting water, air, and soil.

Among the types of mines, the less destructive might be subsurface mining.

This type of mining has a less environmental impact because the disturbance caused on the land surface is minor than the impact caused by surface mines.

However, it still has harmful effects on the water and soil by contaminating them with acids and metals and intercepting aquifers.

Other forms of life are affected as well because of this pollution.

Workers are exposed to even more dangerous conditions.

Although subsurface mines have less permanent damage to the environment, they are still damaging and lack control policies.

Describe what a wave is and how it travels

Nezavi [6.7K]

Waves involve the transport of energy without the transport of matter. In conclusion, a wave can be described as a disturbance that travels through a medium, transporting energy from one location (its source) to another location without transporting matter.
