Answer:

Explanation:

The type of battery that Jackson's toothbrush is using is a secondary cell; this is because it can be recharged (meaning the electrochemical reactions taking place in the battery can be reversed). Batteries generally work in such a way that, while using it, electrons move from the anode of the battery to the cathode. In primary cells, this process continues until there are no electron to be transferred from the anode to the cathode and then the battery "dies" and is disposed. But in a secondary cell, just like the battery of Jackson's toothbrush, when the battery is been recharged, the electrons start moving from the cathode back to the anode; which makes electrons available again in the anode for use.

Explanation:

Answer:

exchange O2 and CO2 gases.

Explanation:

The respiratory system's main function is to exchange oxygen and carbon dioxide gases within the body. The organs that make up the respiratory system include the nose, pharynx and larynx, the trachea, bronchi, and the lungs. Each of these organs help with the process of breathing and/or the exchanging of gases within them.

I hope this help :)

Answer: It should be one only, if I’m wrong I’m sorry

Explanation:

Answer:

They are all used as primary energy sources during exercise. They are each stored in the liver to be used as a ready energy reserve. They each can be broken down to provide ATP to cells.

Answer:

The statement that correctly describes what proteins, lipids, and glycogen have in common is C. they each can be broken down to provide ATP to cells. Proteins, lipids, and glycogen all consist of a group of molecules, which means they can be broken down to these smallest items. ATP, or adenosine triphosphate, is a molecule that can be found in anything, and which we need for everything because it is a source of energy in living beings.

Answer:

Phytoplankton are essential for atmospheric and climate regulation.

Explanation:

Phytoplankton are autotrophs, they use solar energy, along with inorganic carbon and water to produce their own food source via photosynthesis. During photosynthesis, they also produce oxygen, integral for the planet's atmospheric composition.

At their large biomass, phytoplankton contribute to a majority of the oxygen used by consumers (most animals).

             6 CO2 + 6 H2O + light  →  C6H12O6 + 6 O2

Carbon Dioxide + Water + Light       Glucose + Oxygen

Along with fossil fuels, human agricultural practices have contributed large amounts of CO2 to the atmosphere, This causes global warming, a major environmental crisis- global warming also leads to landmass loss, biosphere disruption and reduces biodiversity in mass extinction events.

Phytoplankton carbon cycling produces organic matter which functions as carbon sinks in our oceans. Thus, as phytoplankton use large amounts of CO2, they help combat warming cycles, along with producing O2 in atmospheric and climate regulation.

Answer:

A. stroma

Explanation:

The Calvin Cycle occurs in the inner parts of the chloroplasts, which is also referred to as the stroma.

Answer:  I and II  (1 and 3)

Explanation: The spiders could destroy the ecosystem of a region where it had not been presented, since insects or some mammals are defenseless against this species because they had never seen or interacted with it, it can hunt and reproduce to a great extent, becoming a problem, and by taking flowers from another region totally different from yours (in animal and plant life) can cause serious damage, since these flowers could bring dangerous insects even for humans, and for native species, ending with what can eat.

Rodents are reservoirs and hosts for several zoonotic diseases such as plague, leptospirosis, and leishmanias

Answer:

The Animal Welfare Act: Signed into law in 1966, the Animal Welfare Act (AWA) is the primary federal animal protection law. The AWA mainly involves animals kept at zoos and used in laboratories, as well as animals who are commercially bred and sold like those in puppy mills

Explanation:

Psychometry is a psychic ability in which a person can sense or "read" the history of an object by touching it. Such a person can receive impressions from an object by holding it in his/her hands or, alternatively, touching it to the forehead.

Answer:

Eubacteria are typically classified into five different phylums: Chlamydias, Cyanobacteria (Blue-green algae), Gram-positive bacteria, Proteobacteria, and Spirochetes. Chlamydias are often parasitic bacteria. Cyanobacteria are most commonly known to be aquatic and obtain energy via photosynthesis.

Answer:

passive transport

Explanation:

passive transport moves molecules and ions from a higher concentration to lower concentration without any energy.

Answer:

Key Points

Nutrients and water are absorbed through the plants root system.

Carbon dioxide is absorbed through the leaves.

From seedling to mature plant, there is a complex dynamic between plants and their environment (soil and atmosphere).

Key Terms

germinate: to sprout or produce buds

photosynthesis: the process by which plants and other photoautotrophs generate carbohydrates and oxygen from carbon dioxide, water, and light energy in chloroplasts

nutrient: a source of nourishment, such as food, that can be metabolized by an organism to give energy and build tissue

Explanation:

Plants are unique organisms that can absorb nutrients and water through their root system, as well as carbon dioxide from the atmosphere. Soil quality and climate are the major determinants of plant distribution and growth. The combination of soil nutrients, water, and carbon dioxide, along with sunlight, allows plants to grow. In order to develop into mature, fruit -bearing plants, many requirements must be met and events must be coordinated.

Answer:

What sends oxygenated blood back to the heart from the lungs?

Oxygen-rich blood flows from the lungs back into the left atrium (LA), or the left upper chamber of the heart, through four pulmonary veins. Oxygen-rich blood then flows through the mitral valve (MV) into the left ventricle (LV), or the left lower chamber.

Explanation:

Answer:

cells use checkpoints at the end of G1 phase, end of G2 phase, and move through the cell cycle, do they breeze through from one phase to the next. The spindle checkpoint, at the transition from metaphase to anaphase. The general answer is that internal and external cues trigger signaling.

Answer:

It has a positive change in stroke volume.

Explanation:

The amount of blood pumped out of the left ventricle of the heart during each systolic cardiac contraction is referred to as stroke volume. During systolic contraction, the heart pumps blood into circulation.

Sympathetic nerves also innervate or stimulate the middle muscular layer of the heart wall. Therefore, an increase of activity in the sympathetic nervous system will trigger an increase in the force of contraction of the heart and, therefore, increase stroke volume. An increase in stroke volume also translates to the pressure of blood being pumped through the arteries.
