Answer:
The correct answer is - The neuron's intracellular charge must get more positive to meet a certain thresh hold in order to depolarize. If the neuron does not hit that threshold, then the neuron will not fire
Explanation:
In neuroscience, the depolarization of neurons shows the all or none law which is also called as all or nothing response. It states that all action potentials have the same size and the potential or strength of a nerve cell does not depend on the stimulus strength as all are the same size.
If a stimulus reaches a particular threshold cell or fiber will fire so either it will fire or not cross the threshold this is all or nothing response or law and depolarization is an example of it.
When making yogurt, bacteria and milk are mixed together and set in a warm area. The container is sealed and no gasses are allowed to enter the container. After 24 hours the container is opened, and there is still no gas. Upon tasting the mixture there is a tart flavor. What type of respiration were the bacteria most likely carrying out?
A.
photosynthesis
B.
alcoholic fermentation
C.
lactic acid fermentation
D.
aerobic cellular respiration
Answer:
When making yogurt the tart flavor get in the end is more likely because the bacteria have carried out a type of respiration named lactic acid fermentation (option C).
Explanation:
The process of obtaining yogurt from whole milk involves the association of the bacterial species Streptococcus and Lactobacillus. In order to carry out the lactic acid fermentation that produces yogurt, the bacteria act in a different way:
Streptococcus is in charge of removing the oxygen from the milk product.Lactobacillus promotes the conversion of lactose sugar into lactic acid.This fermentation process leads to the conversion of milk into a coagulated and tart flavor product.
Other options are not correct because:
A. Photosynthesis : is the process that occurs in plants to obtain chemical energy from sunlight.
B. Alcoholic fermentation: in this chemical process alcohol is obtained from the fermentation of a sugar.
D. Aerobic cellular respiration: does not involve fermentation, but the series of processes that convert glucose into energy.

1. The epithelial membrane that lines the closed ventral cavities of the body.
2. The epithelial membrane that lines body cavities open to the exterior membrane
3. Consists of keratinized stratified squamous epithelium.
4. Found lining the digestive and respiratory tracts.
5. Makes up the pleura and pericardium.
6. Lines blood vessels and the heart.
Answer:
Some of these sentences both refer to the same term.
1. The epithelial membrane that lines the closed ventral cavities of the body. - 5. Makes up the pleura and pericardium. This is called the serous membrane.
2. The epithelial membrane that lines body cavities open to the exterior membrane . - 4. Found lining the digestive and respiratory tracts. These statements refer to the mucous membrane.
3. Consists of keratinized stratified squamous epithelium. - cutaneous membrane.
6. Lines blood vessels and the heart. - endothelium.
Explanation:
All of these membranes are formed by epithelial tissue - one of the four basic tissues found in the human body, with important tasks that many times give the organs they're part of their main function.
The epithelium can vary in shape and size in order to adapt to the necessities of the organ. If the organ needs protection from abrasions, like the skin or the stomach, this tissue will have many layers and be called "stratified epithelium". On the other hand, an organ with the function to exchange substances, like the blood vessels or the alveoli, will have only one layer of epithelium, to ease the diffusion of gases and other molecules.
The other three basic tissues are: connective tissue, muscle tissue, and nervous tissue.

The correct order from smallest to largest is:
1. organism
3. population
2. community
4. ecosystem
5. biome
5. biosphere
Explanation:
Biological term related to the number of individual organisms from smallest to largest is organisms, populations, communities, ecosystem, biome, and biosphere.
An organism is a single organism or unity entity in a population, a population is a group of similar individuals that combinedly form a community with other types of population.
A community is a group of various types of populations, that interact with one another. If a community interact with other biotic and abiotic factors it is known as an ecosystem that together with other ecosystems forms a biome

Which type of cell have membrane bound organelles?
prokaryotes
Or
eukaryotes
Answer:
eukaryotes
Explanation:
Like a prokaryotic cell, a eukaryotic cell has a plasma membrane, cytoplasm, and ribosomes. However, unlike prokaryotic cells, eukaryotic cells have: a membrane-bound nucleus. numerous membrane-bound organelles (including the endoplasmic reticulum, Golgi apparatus, chloroplasts, and mitochondria)
Eukaryotic cell have membrane bound organelles. Thus, the correct option is eukaryotic cell.
What is eukaryotic cell?The eukaryotic cell is known as the fully developed and it contain membrane bound organelle. The multicellular organism are made up of the eukaryotic cell and they contain cell organelle it contain mitochondria, ribosomes, RNA, DNA, golgi appratus, and nucleus as well as other cell organelles.
Multicellular organisms are made up of eukaryotic cell and the eukaryotic cell is consist of different cell organelles to carry out different functions in the cell. The multicellular organisms perform different life process in different cells because they have specific cell for specific function.
Amoeba has known as an unicellular organism in which all the activities related to life carried out in a single cell. The example of multicellular organism is human beings and other animals as well plants are also came in the category of multicellular.
Therefore, Eukaryotic cell have membrane bound organelles. Thus, the correct option is eukaryotic cell.

Which of these is a distinguishing characteristic between the domains Bacteria and Archaea?
Answer:
This question lacks options, the options are:
a. Their size
b. The chemical composition of the cell wall and cell membrane
c. Their ability to grow at high temperatures
d. The shape of their mitochondria
The answer is B
Explanation:
Living organisms has been classified into three domains namely; Eukarya, Archaea, and Bacteria. However, domians Archaea and Bacteria are most similar in the sense that they both have cells without a membrane-bound nucleus, hence, they are both PROKARYOTIC. Also, they are both strictly unicellular organisms.
Despite these similarities, differences exists between them. One major difference is in the chemical composition of the cell wall and cell membrane. The cell walls of bacteria cells have a unique structure called PEPTIDOGLYCAN. This is absent in the Archeae group. Also, the cell membrane of Archeae is made up of ether linked lipids compared to the ester-linked lipids that constitutes bacteria cell

How do interdependent factors—such as climate and lack of resources—impact the carrying capacity of an ecosystem?
Answer:
Ecosystems have carrying capacities, which are limits to the numbers of organisms and populations they can support. These limits result from such factors as the availability of living and nonliving resources and from such challenges such as predation, competition, and disease. If this helps you could I possibly have brainliest?
Explanation:
The impact of climate and lack of resources on the carrying capacity of an ecosystem is discussed below :
The carrying capacity of an ecosystem can be described as the maximum amount of organisms which can be naturally catered for giving the resources available in an environment.
Climate has an important role to play in the type of resource available or resources which can thrive in an environment. Similarly harsh climate conditions aren't favorable for survival, hence resulting in low carrying capacity of such ecosystem.
Also, organisms, animals depend on the available resources available in an environment for survival, when the available resources aren't enough to cater for a large population, the carrying capacity of the ecosystem is impeded.
