Protists are difficult to characterize because of the great diversity of the kingdom. These organisms vary in body form, nutrition, and reproduction. They may be unicellular, colonial, or multicellular.

It is hard to demonstrate one certain way a protist reproduces :

Some protists use agamic reproduction at one stage in their life and then use gamic reproduction at another stage in their life.

Thus, Protists are difficult to characterize because of the great diversity of the kingdom.

High-fat diets can play a part in the development of breast, colon, and pancreatic cancer. So, the correct option is A.

A High-fat diet may be defined as a diet consisting of at least 35% of total calories consumed from fats, both unsaturated and saturated fatty acids.

High fat can be acquired from eating excess fatty compounds. There are a number of foods that ensure excess body fat content. Such foods are meat, eggs, and even milk and products that come out of such foods.

Therefore, High-fat diets can play a part in the development of breast, colon, and pancreatic cancer.

answer explanation:

All group 16 elements combine with hydrogen to form hydrides. Acidic nature and bent shape decrease from water. The H-E bond length increases as the bond dissociation enthalpy decrease down the group. Thermal stability and reducing character also decreases because the H-E bond length increases down the group.

The associations are involuntary, digestive tract and arteries  >> smooth; whereas voluntary, tendons, extensors >> skeletal and electrical nodes >> cardiac.

Muscles are a special type of tissue that has the ability to contract in response to a given stimulus.

There are different three types of muscle fibers: cardiac muscle, skeletal muscle and smooth muscle.

Cardiac muscle and smooth muscle are involuntary muscles, whereas skeletal muscle is a voluntary muscle.

https://brainly.com/question/1283837

Answer:

Involuntary: Smooth

Voluntary: Skeletal

Electrical Nodes: Cardiac

Tendons: Skeletal

Digestive Tract: Smooth

Arteries: Smooth

Extensors: Skeletal

Explanation:

Types of muscles. The three kinds of muscle in the body are the skeletal muscle, the smooth muscle, and the cardiac muscle. The skeletal muscles are attached to the bones and allow one to move at will. Because the skeletal muscles are mostly under your conscious control, they are sometimes called "voluntary" muscles. Smooth muscle lines the inside of such hollow organs as the digestive system, bladder, and arteries. Smooth muscles work automatically and are beyond your conscious control. They are referred to as "involuntary" muscles. Cardiac muscle is unique to the heart.

Although skeletal muscles seem to be under your control, a lot happens of which you are not aware. First of all, your posture, even when asleep, is controlled by skeletal muscles without your paying much attention to it. Your mouth, for instance, would flap open if your brain did not maintain a certain tension in your chewing muscles all the time. Your chin would spend a lot of time resting on your chest if your neck muscles didn't hold your head up. And your movements of all kinds would be pitifully awkward if your cerebellum did not coordinate all the muscles necessary to perform even the simplest actions. Just scratching your nose, for instance, requires dozens of muscles to move in exactly the right way at exactly the right time. You are truly "fearfully and wonderfully made."

We will now take a closer look at the other two types of muscles. Skeletal muscles can be attached to other muscles or to bones either directly or by a thin band of connective tissue called a tendon. Do not confuse this tendon with a ligament, which connects bone to bone and not muscle to bone. Two good examples of tendons can be found in the back of your legs. One is the Achilles tendon which attaches the calf muscle in the lower back part of your leg to your heel. The other tendons are on the back side of your knee, called the hamstrings. They serve to attach muscles in the upper back part of the leg to the bones of the lower leg and flex your knee. Locate these structures on your own leg.

The point at which a muscle is attached to the less movable part of the body is called the origin. The point at which a muscle is attached to the more movable part of the body is called the insertion. The biceps muscle of your upper arm is a good example of both these points. The biceps has its origin in your shoulder and its insertion in the bones of the forearm.

Skeletal muscles differ relative to their effect on the body. Those muscles that bend a joint are called flexors, and those muscles that straighten a joint are called extensors. Muscles always work in pairs, one opposing the action of the other. For instance, the upper arm has biceps on the front, which serves as the flexor. The muscle that opposes this motion and serves as the extensor of the forearm is the triceps, which is located on the back of the upper arm. When one muscle contracts, the other must relax. Study the diagram and then see if you can feel the alternating contraction of the biceps and triceps in your own upper arm as you bend and straighten it.

You should be careful to get enough exercise to keep your muscles in good shape. Muscles will grow larger and have better tone, which means they will always be slightly contracted, if they are used. If a person is lazy or is confined to a bed or wheelchair for a prolonged period of time, the muscles not being used will become smaller and lose their tone. This condition is called atrophy. A muscle atrophies at a rate of about 1% a day, so that it will lose a full third of its strength after a month of disuse. Disuse also causes bones to soften by losing their calcium. "Use it or lose it" is a solid maxim of physiology.

Answer:

two traits ,

Explanation:

In an example of pleiotropic genes, the flower color gene studied by Mendel affected a single trait.

Pleiotropy refers to a phenomenon where a single gene influences multiple, seemingly unrelated traits or characteristics in an organism. However, in this specific case of Mendel's flower color gene, it affected only one trait, which is the color of the flower.

Genes are the basic factors of inheritance. They are found in the DNA of all living organisms. They are responsible for transmitting genetic information from one generation to the next and play a crucial role in determining an organism's traits and characteristics.

Intermittent streams have a statistically lower macroscopic invertebrate species diversity than the seasonal streams.

Intermittent streams are ecosystems where water flow is stopped at least twice in a given period of time.

Intermittent streams exhibit biodiversity that is different from other types of streams because species can not be adapted.

The statement environmental influences begin at birth and continue throughout life is definitely False.  

Anything which is present in the surrounding of an organism is called its environment. The environment is surrounded by abiotic and biotic factors.

Environmental influences will not remain the same throughout life. If a human is affected by a natural disease, it will definitely be cured with medications. Environmental influences sometimes behave as genetic diseases, which stay long or sometimes endless.

Mirror neurons respond both when perceiving an action and while executing an action. They provide a direct internal experience of another person's actions or emotions and may be the neurological basis of empathy.

Explanation:

Mirror neurons respond to perceiving an action while executing an action. They provide a direct internal experience of action or emotion of another person and are the neurological basis of empathy.

Mirror neurons are a category of neurons that modulate activity both when an individual executes a specific motor act and also when they observe a similar act performed by another individual.

Mirror neurons activate when for example when monkeys break peanuts when they see others doing the same even in darkness as they hear peanuts being broken.

The mirror neurons are the scientific explanation for empathy.

Answer:

Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities.

The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.
