Please Help!!! Which two body systems are most affected when a person is participating in a long jump?

A. endocrine and digestive
B. endocrine and muscular
C. skeletal and digestive
D. skeletal and muscular

Answers

The two-body systems that are most affected when a person is participating in a long-jump are skeletal and muscular (Option D).

The muscular system is composed of three different types of muscles: smooth muscle, cardiac muscle and skeletal muscle.

The skeletal muscles are muscles responsible for controlling voluntary movements (e.g., jump) and they are attached to the skeleton by a type of connective tissue known as tendon.

The skeletal system is composed of all bones of the body and they are responsible to provide support and protection to the internal organs.

In conclusion, the two-body systems that are most affected when a person is participating in a long-jump are skeletal and muscular (Option D).

Why are invasive species dangerous to the environment?
A)They pollute the environment.
B)They are always predators.
C)They threaten biodiversity.
D)They bring abiotic factors.

Answers

Answer:

C

Explanation:

They threaten the other animals. They can take their food, homes, and they don't have natural predators.

Invasive species are dangerous to the environment as they threaten the biodiversity. Thus, the correct option is C.

Invasive species are those imported species that are able to thrive rapidly in another foreign area by adapting and reproducing quickly.

Invasive species of plants and animals lead to an increase in the competition for survival, which results in decrease in the population of the native species.

The invasive species also affect the food web that is existing in the particular ecosystem, because of which other all organisms which are part of the food web are affected. They outcompete the native species for food,

Thus, biodiversity is threatened due to the invasive species.

Explain how the structures of plant tissues and organs are directly related to their roles in physiological processes.

Answers

Answer:

How the structures of plant tissues and organs are directly related to their roles in physiological processes.

o Plant organs are limited to roots, stems, leaves, flowers, fruit and cones.

o Physiological processes are limited to photosynthesis, cellular respiration,

transpiration, and reproduction.

o Plant tissues are limited to meristematic, ground, dermal and vascular tissues.

o Plant structures are limited to cambium, guard cells, phloem, seed, stomata and

xylem

Explanation: Hope this helps have a safe and happy new year

Roots, stalks, leaves, flowers, fruit, and cones are the only organs found in plants. Photosynthesis, metabolic processes, transpiration, and fertilization are the only physiological activities.

Plant and plant tissues:

Photosynthesis and the movement of mineral-containing water ions are critical processes in the development of healthy plants. Plants have three primary structures or organs:

LeavesStemsRoots

They're made up of groupings of specialized tissues with structures that are tailored to the functions they do.

Adaptations are distinctive features that help plants survive in their specific settings. Plants rely on their specialized structures to provide their fundamental requirements, protect themselves from predators, and aid reproduction.

the ability to maintain homeostasis

the ability to maintain homeostasis

the ability to grow and develop

the ability to grow and develop

the ability to adapt and evolve

the ability to adapt and evolve

the ability to reproduce

Answers

Answer:

Sweating helps the human body maintain homeostasis by cooling the body when it starts to overheat so the internal temperature is kept more or less the same. When sweat evaporates from the skin, it uses up some of the excess heat energy on the skin, thus helping to keep the body cool.

According to cell theory, all living things are made of cells, and living cells come only from other living cells. Gene theory states that the characteristics of living things are controlled by genes, which are passed from parents to their offspring.

Sample answer: The concentration of oxygen in the atmosphere is maintained at 21 percent by a balance between two opposing processes: removal of oxygen from the atmosphere by most living things and addition of oxygen to the atmosphere by living things such as plants.

Sample answer: The human ability to sweat is an adaptation that helps maintain homeostasis in a hot environment by removing heat from the body when it evaporates. Like other adaptations, the ability to maintain homeostasis by sweating evolved by natural selection sometime in our evolutionary past.

a. Gene theory

b. Homeostasis

B

An adaptation is a trait that helps a living thing survive and reproduce in a given environment. Sample example. The chameleon’s ability to change color to match their background is an adaptation.

False

False

Humans began life as a single cell because we develop from a fertilized egg cell.

Gene theory states that genes are passed down from parents to their offspring. Genes determine the characteristics or traits of an organism. If these traits are particularly beneficial or adaptive, natural selection will cause the organisms with beneficial traits to produce more offspring compared to those without the beneficial traits. This results in a change in traits over time, which is called evolution.

No. Evolution is defined as a change in the characteristics of living things over time. Evolution through natural selection causes differences in the amount of offspring produced. Having offspring (or not) is, by definition, more than one generation.

Sample answer. I think that when ancestors of chameleons could change their color to match their background, they were less likely to be detected and killed by predators than those that couldn’t change their color. Therefore, the individuals that had the color matching ability were more likely to survive and reproduce than those that didn’t. This is an example of natural selection. Over time, this led to the population evolving the color changing ability, as those that didn’t have the ability died out.

Why is some amount of air is left inside in your lungs after inhalation

Answers

Answer: Residual volume (RV) is the volume of air remaining in the lungs after maximum forceful expiration. In other words, it is the volume of air that cannot be expelled, thus causing the alveoli to remain open at all times. The residual volume remains unchanged regardless of the lung volume at which expiration was started. The residual volume (RV) is the amount of air that is left after expiratory reserve volume is exhaled. The lungs are never completely empty: There is always some air left in the lungs after a maximal exhalation.

So your answer will be Residual volume...

Hope this helps........ Stay safe and have a Merry Christmas!!!!!!!!! :D

It is left because exhaling will never remove all air from your lungs, if it did your body would shut down due to lack of oxygen to all organs. It distributed the atoms throughout the body.

The option that represents the activation energy of a catalyzed reaction is C. X; the activation energy is greater in an uncatalyzed reaction.

Activation energy simply means the minimum amount of energy that should be provided for compounds that'll result in a chemical reaction.

It should be noted that the activation energy for uncatalyzed conversion to the products will be more than that of the catalyzed reaction. In this case, X; the activation energy is greater in an uncatalyzed reaction.

Use the earthquake magnitude scale to predict the amount and type of damage residents should expect from future earthquakes of similar magnitude.
Then suggest a way to minimize the effects of future earthquakes on the skyscraper.

Answers

According to the scale, residents should expect major damage and the potential for the skyscraper to collapse if a future earthquake were to occur.
Ways to minimize future earthquakes impact on the skyscraper could be using stronger materials, creating better routes to quickly escape should an earthquake occur, and overall a more supported structure that can withstand the earthquakes magnitude.
