Differentiate between sub-cellular and acellular particles with examples
Answer:
Explanation:
Sub-cellular particles are particles smaller than the living cell and are found suspended in the cytosol (of a cell) like the nucleus, golgi complex and the mitochondria.
While acellular particles/organisms are particles that do not have a cell like the virsues, viroids and prions. They are not alive/inactive outside a living environment but become active immediately they are inside a living environment (like a cell).
Sub-cellular particles are structures that are found within a cell. These structures perform specific functions and are essential for the cell to carry out its biological processes.
Examples of sub-cellular particles include organelles such as the nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, and lysosomes. These structures are composed of both proteins and lipids and are enclosed by a membrane.
Acellular particles, on the other hand, are particles that do not possess a cellular structure and are not alive. These particles are much smaller than cells and are unable to carry out any metabolic processes.
Examples of acellular particles include viruses, prions, and viroids. These particles are composed of either DNA or RNA and can replicate themselves only within a host cell. They do not have their own metabolism and rely on the host cell for replication and survival.

What are muscle cells?A muscle cell exists also known as a myocyte when directed to either a cardiac muscle cell or a smooth muscle cell as these exist both small cells. A skeletal muscle cell exists long and threadlike with many nuclei and is named a muscle fiber. Muscle cells originate from embryonic precursor cells named myoblasts.
The muscle cells exist as a specialized kind of cell (one of the four tissues) that can contract to exert action.
These cells (muscle cells) can be paralyzed by utilizing various inhibitors of movement such as poisons.
In conclusion, the cells in the prey that exist most likely affected by the poison present in the darts exist the muscle cells.

ANP is a hormone that causes:_________ a. constriction of the afferent arterioles and inhibition of renin release. b. dilation of the afferent arterioles and inhibition of renin release. c. dilation of the afferent arterioles and release of renin. d. constriction of the afferent arterioles and release of renin.
Answer:
b. dilation of the afferent arterioles and inhibition of renin release.
Explanation:
Atrial Natiuretic Peptide is a hormone which is mainly made and secreted in the atria. It helps in the regulation of blood pressure levels with the use of the kidney through an increase in water and sodium excretion.
The hormone helps in the regulation of blood pressure by ensuring there are dilation of the afferent arterioles to give room for increased flow of blood due to the increased pressure. Study also shows that the enzyme inhibits the release of renin.

Explanation:
Pasteur's experiments proved that ________. Pasteur's experiments proved that ________. spontaneous generation can only occur if nutrient broth is left open to the environment cells cannot survive in swan-necked flasks preexisting cells present in the air can grow in sterilized nutrient broth sterilizing nutrient broth prevents spontaneous generation in order to grow, cells need to be supplied with oxygen
Answer:
preexisting cells present in the air can grow in sterilized nutrient broth
Explanation:
Spontaneous generation, which is the theory that life can arise from nonliving matter, has long been believed to be the way living organisms develop. However, in 1858, a French scientist called Louis Pasteur disproved the theory of spontaneous generation.
Louis Pasteur conducted an experiment to show that it is the existing microorganisms in air that causes life to grow and not the air itself. Pasteur made use of a swan-necked flask, which contained a sterilized (by boiling) broth. The swan-necked flask was designed in such a way that it would allow air to enter but trap any airborne microorganism, preventing them from reaching the broth.
Hence, if it were truly air and not existing life organisms that caused life growth, organisms should begin to grow from the broth. He conducted another experiment where be broke the neck of the flask to allow the entry of microorganisms into the sterilized broth and found out that growth of microorganisms occured on the broth.
Therefore, Pasteur, via his experiment was able to prove that preexisting cells present in the air can grow in sterilized nutrient broth if allowed entry but when there is no entry, there would be no life growth. This experiment disproved the theory of spontaneous generation.
At label ________, the cell is not hyperpolarized; however, repolarization is in progress, as the sodium channels are inactivated or becoming inactivated, and many potassium channels have opened.
Answer: C
Explanation:
When a neuron receives a stimulus, the sodium channels present in the membrane are opened, and therefore Na+ enters the cell in favour of the concentration gradient, so that the membrane potential changes to positive by means of ion exchange, producing depolarization. If this depolarization reaches a certain threshold value, an action potential is generated. The next step is the opening of the potassium channels and the inactivation of the sodium channels, so that the repolarization of the membrane takes place. The sodium channels, will return to the closed state in the hyperpolarization to continue in this state during all the rest potential achieving the action potential to return to -70 mV (repolarization).; until the arrival of a new action potential which produces the activation and opening of the sodium channels, repeating the cycle again and generating a new depolarizing action. This process is part of the synaptic transmission.
So, hyperpolarization is any change in the cell's membrane potential, which makes it more polarized. This means, hyperpolarization is an increase in the absolute value of the cell's membrane potential. Thus, changes in membrane voltage where the membrane potential is more distinctly positive or negative are hyperpolarizations.
During the repolarization period after an action potential, the membrane potential is more negative than when the cell is in "rest period". In the picture, this repolarization period is about 1-2 milliseconds. So, repolarization is the time in which the membrane potential is hyperpolarized with respect to the resting potential.
In the attached figure, part C indicates this repolarization period.

Light level is an important factor in aquatic ecosystems.
The physical or chemical parts of the environment that affect the organisms that are in that environment.
What is aquatic ecosystem?An aquatic ecosystem is a water-based environment. Abiotic factors are the non-living components that form the environment in which organisms subsist in a current.
The main abiotic factors in the marine environment are as; light, temperature, salinity, and hydrostatic pressure. dissolved oxygen, acidity (pH), salinity and depth.
Here Without pollution or acid rain, most lakes and streams would have a pH level of around 6.5.

Explain why fermentation stops after
a certain time in making
making bread?
Answer:
The yeast die at 140° F
Explanation:
The fermentation process is caused by the living organisms called yeast feeding on the sugar in the dough. As the yeast feed on the sugar they release CO² which causes the bread to rise but once the bread in the oven reaches 140° all the yeast are killed off and the fermentation process stops.
The process of fermentation stops after a certain time in making bread because the organism which carries this process has been killed.
What do you mean by Fermentation?Fermentation may be defined as a process a chemical process by which molecules such as glucose are broken down anaerobically in the presence of yeast.
During fermentation, the yeast produces excess carbon dioxide due to which the dough of bread swells. But after the completion of fermentation when bread places in the oven or any other warmer temperature, it killed the yeast, and hence fermentation stops.
Therefore, the process of fermentation stops after a certain time in making bread because the organism which carries this process has been killed.
