Answer:
Viruses are not alive
Explanation:
Viruses are acellular structures capable of performing some biological functions.
What are viruses?Viruses are parasitic structures made of an outer protein capsid and genetic material which are able to replicate in a living cell and thus cause infection in the cell.
Viruses hijack the replicative machinery of the host to produce copies of its own genetic material. A single infected cell is capable of producing thousands of viruses.
The virus only injects the nucleic acid inside the target cell, the envelope and capsid are left outside. The hijacked genetic machinery of the host produces further copies of the nucleic acid, capsid and envelope.
These structures are assembled to give rise to new viruses.
If a large number of viruses are synthesized rapidly, it results in cell lysis. This type of infection is called the lytic cycle.
If the virus genome incorporates with the host genome, it is present there silently and being replicated. Upon receiving an activation signal lytic cycle is activated. It is called the lysogenic cycle
Therefore, viruses are acellular structures capable of performing some biological functions.

What can be used to measure the rate of photosynthesis
Answer:
the answer it at the bottom
Explanation:
Uptake of CO2 by plants: Since CO2 is needed for photosynthesis, measuring how much of it is taken up by the plants gives us information on how much of photosynthesis is happening.
Release of O2: The amount of O2 produced during photosynthesis can be measured.

Nucleic Acids
Carbohydrates
Lipids
O Proteins
Answer:
Okay, I got this from google and my notes but the cells inside of a cell membrane are composed primarily of fatty-acid-based lipids and proteins.
Explanation:
Membrane lipids are principally of two types, phospholipids and sterols (generally cholesterol). These membranes are composed primarily of phospholipids and proteins and are typically described as phospholipid bi-layers. They also contain cholesterol in the phospholipid bilayer.
Most pneumonia infections are caused by a virus or bacteria. What characteristic could scientist use to distinguish an infection caused by bacteria from an infection caused by a virus? Group of answer choices The bacteria would grow by itself outside the person. The virus would have DNA. The bacteria would make another person sick. The virus would have proteins.
Answer:
The bacteria would grow by itself outside the person
Explanation:
The bacteria would grow by itself outside the person. - this is correct. Bacteria are independent organisms that do not need other cells to replicate. However, viruses require the cell's machinery to divide and cannot survive independently
The virus would have DNA. - Both bacteria and viruses have DNA (or the virus might have RNA)
The bacteria would make another person sick. - Both viruses and bacteria could make another person sick
The virus would have proteins - Both viruses and bacteria have proteins

Answer:
14. f. diffusion
15. a. excreting waste
16. b. exocytosis
17. a, endocytosis
Explanation:
14. The movement of molecules from a high concentration to a low concentration is diffusion. Active transport uses energy to move molecules against their concentration gradient (from low to high). Osmosis specifically refers to water molecules. Endocytosis is the movement of molecules inside the cells via the cell membrane engulfing it.
15. The membrane controls the substances that enter and exit the cell, therefore it is involved in excreting waste products from inside the cell.
16/17 Endocytosis is engulfing substances to bring them inside the cell. Exocytosis is the reverse process, where substances exit the cell by fusing with the cell membrane. The movement of molecules from a high concentration to a low concentration is diffusion. Osmosis specifically refers to water molecules.

Answer:
1. For generating healthy cells to form replacement organs like brains
Stem cells can be used for curing heart disease by regenerating damaged heart tissue. The correct option is 4.
What is stem cell?Stem cells are the raw materials of the body, the cells that give rise to all subsequent cells with specific responsibilities.
Under the right conditions, stem cells divide to establish more cells known as daughter cells in the body or in a laboratory.
Bone marrow stem cells, for example, may be able to generate bone or cardiac muscle cells.
This research has resulted in early-stage clinical trials to assess the effectiveness and safety of the product in humans.
Adult stem cells, for example, are currently being examined in people suffering from neurological or cardiovascular disease.
Thus, the correct option is 4.
