Because of their capacity for rapid growth and reproduction, or because their new environments are devoid of any native predators or pests, invasive species frequently thrive in their new ecosystems. Thus, option B is correct.

What is a characteristic of invasive species?

An invasive species doesn't develop slowly; on the contrary, they accelerate their growth because they are superior to all other species and have taken over the area completely.

Because of this, invading species may pose a threat to native species and interfere with crucial ecosystem processes.

A species must be easily adaptable for it to be invasive. It needs to multiply swiftly. It must result in harm to local property, the local economy, or the local fauna and flora. Accidental introduction of invasive species into a new area is common.

They are so successful because they can adapt and aren't intrusive. Because they have no competition, they are thriving while not being threatened.

Therefore, They take resources from native species.

Colder climates promote higher biodiversity because they are usually larger in size. This provides space for more organisms.

Answers

Answer:

False  

Explanation:

The relationship between climate and biodiversity can be defined as follow: warmer climates are generally associated with higher biodiversity because these conditions promote the life of primary producers such as those organisms that produce organic compounds using simple substances and energy from light. Primary producers form the basis of the food chain, thereby their presence is fundamental to generate sustainable high biodiversity environments. For example, warmer climates such as tropical ecosystems promote plants (i.e., primary producers) to grow year-round, thereby supporting more organisms (i.e., species richness) that rely on plants.

Answer: No atoms can be created and no atoms can be destroyed.

(don't know if thats what you were looking for)

Explanation:

Well according to Dalton’s theory atoms of the same element are alike in all respects and atoms of different elements are different. So elements can be combined to make a new element but can not be the same element. It’s kinda hard to explain but essentially if it’s the same then it will stay the same and if it’s different then it will stay different. It can’t change in that regard but it can be combined to create anew.

The idea of laissez-faire, or how much the government should do, is

DONE

Answers

Answer:

Laissez-faire means that the government does not interfere with people's right to pursue happiness.

The idea of laissez-faire, or how much the government should do, is debated heavily.

Explanation:

Laissez-faire is the main concept defended by economic liberalism and capitalism, mainly in the USA and other countries that adopt this type of concept. In a simple way, Laissez-faire can be defined as the separation of the State and the commerce of a region. This means, that in places where Laissez-faire is adopted, the State, ie the government, does not have the right to interfere in any type of commercial relationship and should only be responsible for guaranteeing property rights and consumer protection, otherwise, trade must regulate itself, within its own limits.

While many people see this policy as beneficial, preventing government from interfering with people's happiness, others believe that Laissez-faire is not beneficial and that government interference, or lack of it, should be discussed.

Your teacher will grade your responses to questions 24 and 25 to ensure you receive proper credit for your answers. Identify the systems that move your body, and explain how these systems work together.

Answers

Answer: Nervous system, skeletal system, muscular system. The nervous system control the muscles and the skeletal system helps to support those muscles.

Explanation:

The nervous system consists of a set of cells specialized in conducting electrical and chemical signals, called neurons, and glial cells that are supportive. The nervous system picks up external stimuli from the environment or signals from the organism itself (internal stimuli), and this information is transmitted by nerves to the brain, where everything is processed and a signal is emitted that causes the contraction of certain muscles.

The nervous system is divided into central and peripheral systems. The central nervous system comprises the spinal cord and brain, while the peripheral nervous system comprises the nerves that connect the central nervous system to the body. Within the peripheral nervous system, there is a sensory (afferent) nervous system responsible for incorporating information from receptors (such as the eyes, the skin for touch, etc.), and a motor (efferent) system that carries the information to the muscles.  

From the functional point of view, it is also differentiated into somatic and autonomic system. The somatic nervous system consists of neurons that control voluntary actions, while the autonomic nervous system is responsible for involuntary functions. And within the latter group are included the sympathetic nervous system (which is activated in situations of danger to stimulate many organ functions that cause a rapid response), the parasympathetic (which is involved in the regulation of several organs and its action is opposite to that of the sympathetic nervous system) and the enteric nervous system in the gastrointestinal tract.  

The muscular system is a set of muscles that can be controlled voluntarily, if we refer to skeletal muscles. Their main function is mobility, an action that takes place when stimuli from the nervous system provoke the contraction of the muscle fibers. There are three types of muscle tissue: skeletal, smooth and cardiac, and all of them are able to contract but they differ in certain characteristics, location and the way in which the contraction is regulated, which can be voluntary or involuntary.  

Muscle tissue receives electrical impulses from the nervous system and responds to them by generating a contraction movement. The neuromuscular junction plate is the connection established between a motor neuron and a muscle, by means of which the neuron transmits electrical impulses to the muscle fiber and between them there is a space called synaptic cleft. When a nerve impulse called action potential travels through the axon of a motor neuron, the neurotransmitter acetylcholine is released into the synaptic cleft, which binds to the muscle cell membrane and causes it to alter its membrane potential causing a depolarization that triggers contraction.  

Finally, the skeletal system consists of a rigid structure formed by bones, and has several functions such as mechanical support, maintenance of posture, makes possible the bipedal position and protection of vital organs. The joints between two adjacent bones, called articulations, make muscular movements possible. In addition, the bones serve as insertion sites for the tendons of the muscles, which allow movement that is controlled by the nervous system and carried out mainly by the muscular system.

So, the nervous system control the muscles and the skeletal system helps to support those muscles.

Which of the following shows the stage of mitosis in the correct order?​

Answers

answer: B !

hope this helps! please mark me as brainliest :)

Prophase, prometaphase, metaphase, anaphase, telophase, cytokinesis is the correct order of mitosis. Therefore, option (B) is correct.

Mitosis is a cellular process that ensures the accurate division of a cell's genetic material into two identical daughter cells. It consists of several distinct phases that occur in a specific order.

Interphase: The cell prepares for division by growing, duplicating its DNA, and synthesizing necessary proteins.

Prophase: Chromatin condenses into visible chromosomes, the nuclear membrane disintegrates, and spindle fibers form.

Metaphase: Chromosomes align at the center of the cell, known as the metaphase plate, and attach to spindle fibers at their centromeres.

Anaphase: Sister chromatids separate and are pulled to opposite ends of the cell by the spindle fibers.

Telophase: Chromosomes reach the opposite poles of the cell, and new nuclear membranes form around them. The chromosomes begin to decondense.

Cytokinesis: The cytoplasm divides, leading to the formation of two distinct daughter cells, each containing a complete set of chromosomes.

What characteristics of the blood cell helps it to pass freely through blood capillaries

Answers

Answer:

The cell is flexible and assumes a bell shape as it passes through extremely small blood vessels. It is covered with a membrane composed of lipids and proteins, lacks a nucleus, and contains hemoglobin—a red iron-rich protein that binds oxygen.

Answer:

The cell is flexible and takes the form of a bell through extremely small blood vessels. It is clothed in a fluid and protein-membrane, lacks a nucleus, and has hemoglobin—a rich red iron protein that binds oxygen.

Explanation:

The hemoglobin in red blood cells contains four iron-binding heme groups.

Heme groups of hemoglobin are binding on oxygen. Each molecule of hemoglobin can bind up to four molecules of oxygen.

Hemoglobin has a cooperative binding affinity to oxygen. The saturation of the molecule increases by oxygen. The connection of the initial molecule of oxygen affects the form of the other binding sites. For additional oxygen molecules, the binding becomes more favorable.

The four iron-binding hemo-groups are located in each hemoglobin molecule. Hemoglobin is known as oxygen-bound hemoglobin.

The reversible carbon dioxide is transformed into the carbonic acid reaction by the enzyme carbenoid anhydrase by the Red blood cells altering the blood PH.

Instead of being converted to carbonic acid, pH is controlled by carbon dioxide bindings to hemoglobin.

CO2: The enzyme found in RBCs catalyzing the reaction between carbonic anhydrase and carbonate dioxide and water.

Co-operative binding: When a first molecule is binding to a binding location, the same molecule is favored for the remainder of the binding locations by means of increased binding affinity.

Explanation:

Small-scale biological disturbance.

Answer:

O D. small

Explanation:

In ecology a disturbance is an event that causes a change in the environment. There are small-scale disturbances and high-magnitude disturbances. Small-scale disturbances are typically driven by biological processes -for example the fall of a tree- while high magnitude disturbances are typically driven by physical processes -for example, storms-. Small-scale disturbances as single-tree blowdowns are very important  to create and maintain diversity and heterogeneity in the forest.

Ecosystem ecology refers to how ______ and ________ come into an environment and move around.

Answers

1. biotic

2.Natural environment

Ecosystem ecology refers to how energy and nutrients come into an environment and move around.

What is ecosystem?

Ecosystem ecology is concerned with the interactions and movements of energy and nutrients within an ecosystem, which are critical for understanding how ecosystems work.

Photosynthesis by primary producers, such as plants, introduces energy into ecosystems, which then flows through the food chain to consumers.

Nutrients such as carbon, nitrogen, and phosphorus cycle through the ecosystem via biological and geological processes and are critical for the ecosystem's health and productivity.

Understanding how energy and nutrients enter, move, and cycle within ecosystems is therefore critical for understanding ecosystem functioning and sustainability.

Thus, the movement of energy and nutrients in an ecosystem is referred to as ecosystem ecology.
