Answer:
To move substances against a concentration or an electrochemical gradient, the cell must use energy. This energy is harvested from ATP that is generated through cellular metabolism. Active transport mechanisms, collectively called pumps or carrier proteins, work against electrochemical gradients.

the nerve impulse is an electrical current that travels along dendrites or axons.
Answer:
i think your answer is true! :)
Explanation:
The statement: The nerve impulse is an electrical current that travels along dendrites or axons is true.
Dendrites are the branched projections of a neuron that receive signals (chemical or electrical) from other neurons or from sensory cells. They are often referred to as the input zone of the neuron, as they receive and integrate incoming signals from other neurons.
A nerve impulse is an electrical signal that travels along the dendrites or axons of a neuron. When a neuron is stimulated, it generates an electrical charge that spreads along its membrane, causing an action potential.
This electrical signal then travels along the axon of the neuron, where it can be transmitted to other neurons or to muscle cells or glands. The speed at which the nerve impulse travels can be influenced by factors such as the diameter of the axon, the presence of myelin sheaths, and the concentration of ions inside and outside of the neuron.Therefore, the mentioned statement about the nerve impulse is true.

D. massive compact halo objects
E. spiral galaxies
F. galaxy clusters
Answer:
A. Weakly.. B. Black.. D. Massive..
Explanation:
Well, I already took the quick check and got them wrong, and then got the answers for y'all
The options that scientists might think of to make up dark matter are as follows:
Weakly interacting massive particles.Black holes.Massive compact halo objects.Thus, the correct options for this question are A, B, and D.
What is meant by Dark matter?Dark matter may be defined as the type of particles that do not absorb, reflect, or emit light significantly. Due to this, they cannot be exposed by visualizing electromagnetic radiation. The materials of dark matter can not be examined directly.
According to the context of this question, dark particles considerably include weakly interacting massive particles along with the part of black holes and massive compact halo objects. Hypothetically, it is believed that approximately 85% of the matter in the universe accounts for dark matter.
Therefore, the correct options for this question are A, B, and D.

what are four examples of nutrients cycled in a biogeochemical cycle
Answer:
The Gaseous cycles include those of nitrogen, oxygen, carbon, and water; while the sedimentary cycles include those of iron, calcium, phosphorus, sulfur, and other more-earthbound elements.
Explanation:
Major examples are carbon, phosphorus, nitrogen, and oxygen in nutrient cycles in the biogeochemical cycle.
What are important nutrients in the biogeochemical cycle?Most of the elements are important to flow in the ecosystem to obtain living things and their surrounding environment in a balanced state.
This cyclic flow provides energy at every level in the ecosystem, carbon is an important substance synthesis during the photosynthesis process and this plays role in energy molecule flow in a particular direction.
In the biogeochemical cycle carbon cycle, oxygen cycle, nitrogen, and phosphorus cycle flow between the living organism and nonliving matter.
Therefore nitrogen, phosphorus, oxygen, and carbon are major nutrients in a biogeochemical cycle.

What is the function of each lymph organ?
Explanation:
The main role of the lymphatic system is the transport of cells of the immune system during the activation of immunity, lipids in the form of lipoproteins, as well as the introduction into the systemic circulation of various objects (small and large molecules, liquids, infectious agents, etc.), packed in delivery vehicles - exosomes and vesicles
The main role of the lymphatic system is the transport of cells of the immune system during the activation of immunity, lipids in the form of lipoproteins.
What is lipoprotein?Particles called lipoproteins are comprised of protein and fat (lipids). They deliver cholesterol to your cells through your bloodstream.
High-density lipoprotein, or "good" cholesterol, and low-density lipoprotein, or "bad" cholesterol, are the two main categories of lipoproteins.
LDL comes in the form of lipoprotein. These lipoproteins transport cholesterol to the artery cells. High levels of LDL particles can cause cholesterol to accumulate in your arteries and create blockages known as plaques. The term "hardening of the arteries" or atherosclerosis refers to this condition.
Therefore, The main role of the lymphatic system is the transport of cells of the immune system during the activation of immunity, lipids in the form of lipoproteins.

What is the source from where organisms get glucose?
This is apart of cellular respiration
Answer:
The source of glucose molecules in plants is the product formed by the process of photosynthesis which is ultimately stored in the parts of plants. In animals, glucose is formed by the oxidation of carbohydrates which are obtained from food.
Explanation:
In the process of photosynthesis, plants and other photosynthetic producers create glucose, which stores energy in its chemical bonds. Then, both plants and consumers, such as animals, undergo a series of metabolic pathways—collectively called cellular respiration.
