During apoptosis, which cellular organelle does the work of breaking up the nucleus and causing the cell to die?
ribosome
mitochondrion
lysosome
Golgi apparatus
Answer: Lysosomes
Explanation: Lysosomes are involved with various cell processes. They break down excess or worn-out cell parts. They may be used to destroy invading viruses and bacteria. If the cell is damaged beyond repair, lysosomes can help it to self-destruct in a process called programmed cell death, or apoptosis.
Question: As a result (because) of diffusion, the concentration of many types of substances:
A: always remains greater inside a membrane.
B: eventually becomes balanced/equilibrium on both sides of a membrane.
C: always remains greater on the outside of a membrane.
|| ▼ Answer ▼ ||
B: eventually becomes balanced/equilibrium on both sides of a membrane.
|| ✪ Explanation ✪ ||
Diffusion is the movement of molecules from a high to a low concentration. The effect of diffusion on different substances' concentrations is balance/ equilibrium on both sides of a membrane. In the process of the movement of molecules, the concentration becomes balanced. A typical example of diffusion is a perfume sprayed inside a room. The smell of the perfume will eventually be balanced in the entire room.

How are proteins related to DNA? What con cause damage or a change in DNA, and how does that change the structure and function of proteins?
Answer:
hi there, proteins are related to DNA because DNA carries the instruction for synthesizing proteins, which can code for a certain amino acids based on the sequence.
Explanation:
A change in base sequence can be either good or bad. But... Usually... a mutation could be a main factor that changes the sequence of the protein, which causes it to code for a different amino acid than the original. Base pairs could either substituted, deleted, or inserted, which usually are what a mutation could be caused by or consisted of. This is also known as a gene mutation, which are changes in genes .

What adaptation has the stigma developed that helps with fertilization?
An adaptation in the stigma that helps with fertilization is the ability of pollen grains to germinate on this structure. It allows plants to reproduce.
What is an adaptation?
An adaptation can be defined as a type of trait that allows organisms to survive and reproduce in particular conditions.
Adaptation favors the process of natural selection, which involves differential survival and reproduction.
Moreover, stigma is a plant structure that receives pollen grains (male gametes) during fertilization.

A 30.0 x 10^8 L sample of nitrogen inside a rigid, metal container at 19.50 °C is placed inside an oven whose temperature is 78.50 °C. The pressure inside the container at 19.50 °C was at 864.5 psi. What is the pressure of the nitrogen after its temperature is increased?
Answer:
Answer:
3.31 atm.
Explanation:
Gay-Lussac's law states that for a given mass and constant volume of an ideal gas, the pressure exerted on the sides of its container is directly proportional to its absolute temperature.
∵ P α T.
∴ P₁T₂ = P₂T₁.
P₁ = 3.00 atm, T₁ = 20.0 °C + 273.15 = 293.15 K.
P₂ = ??? atm, T₂ = 50.0 °C + 273.15 = 323.15 K.
∴ P₂ = (P₁T₂)/T₁ = (3.00 atm)( 323.15 K)/(293.15 K) = 3.307 atm ≅ 3.31 atm.

How do you think a human egg is similar to a chicken egg? How are they different ?
Answer:
They both eventually lead to the birth of a chicken or human. And they start very similarly. They are very different, also, because instead of having a physical egg, humans have oval eggs that eventually make the baby, before birth. Chickens on the other hand give birth to the chick that is still inside the egg.

What are the two divsions of the peripheral nervous system?
Answer:
The answer will be somatic nervous system and autonomic nervous system.
Explanation:
Nervous system contain many interconnecting nerves that helps brain to respond according to stimuli. The nervous system is divided into central and peripheral nervous system. Peripheral nervous system again divided into the somatic nervous system and the autonomic nervous system.
What is nervous system?The peripheral nervous system consists of nerves that comes out from brain and spinal cord.
These nerves helps to form a network for communication between central nervous system.
Peripheral nervous system is divided into:
Autonomic nervous system: It is visceral efferent system as it sends motor impulse to visceral organs.Somatic nervous system: It contain sensory and motor neurons that sends and receive sensory information from motor neurons.Thus, there are two divisions of peripheral nervous system, these are autonomic and somatic nervous system.
