In a cell, the fluid within the cell membrane is called
And the fluid Outside the cell membrane is called:
cytoplasm; interstitial fluid
interstitial fluid: cytoplasm
interstitial fluid: tissue fluid
tissue fluid: interstitial fluid
In a cell, the fluid within the cell membrane is called cytoplasm, and the fluid Outside the cell membrane is called interstitial fluid. The correct option is A.
What is cytoplasm?The gelatinous solvent that fills the inside of a cell is known as cytoplasm. It is made up of water, salts, and organic molecules.
Certain intracellular organelles, including the nucleus as well as the mitochondria, are separated from the cytoplasm by membranes.
The cytoplasm of a cell performs all functions related to cell expansion, growth, and replication.
Interstitial fluid can be found in the spaces between cells. It is caused by substances leaking from blood capillaries.
It aids in the delivery of oxygen and nutrients to cells as well as the removal of waste products.
Glucose, salt, fatty acids, and minerals such as calcium, magnesium, and potassium are all found in interstitial fluid.
Interstitial fluid contains nutrients from blood capillaries. It can also contain waste products from metabolism.
Thus, the correct option is A.

Which of the following is an example of how culture can help humans
survive?
A. Inventing tools can help humans survive in their environment.
B. Overusing resources can make a survival practice unsustainable.
O .
C. Developing different religions can lead to conflict among
societies.
D. Having opposable thumbs helps humans grasp objects.
Answer : A
Explanation:
Inventing tools can help humans survive in their environment. Therefore, option (A) is correct.
Why inventing tools help human survive?Culture refers to the shared beliefs, values, practices, and knowledge that characterize a group or society. Humans have relied on culture to survive and thrive for thousands of years. Inventing tools is an example of how culture can help humans survive. By creating and using tools, humans are able to adapt to and manipulate their environment to meet their needs. For example, early humans used tools to hunt, gather food, and build shelters, which helped them survive in their environment.
Overusing resources can lead to unsustainability and environmental degradation, which can threaten human survival. Developing different religions can lead to conflict among societies and does not necessarily help humans survive. Having opposable thumbs is a physical adaptation that has helped humans develop complex motor skills, but it is not an example of how culture helps humans survive.

It is based on phagocytes as well as natural antimicrobials that will immediately go into action once foreign organisms are detected in the body to eliminate any threats these organisms might pose.
Describe how humans benefit from photosynthesis
Answer:
The energy we get from the food we eat originally came from plants, which absorbed energy from the sun. Photosynthesis is also important because of the oxygen it produces. They recycle the carbon dioxide we breathe out and turn it back into oxygen so that we never run out.
Explanation:
Answer:
Equally importantly, photosynthesis is the source of oxygen and also removes carbon dioxide from our atmosphere. Oxygen is required for cellular respiration, the process by which food is broken down into energy. Thus, human beings are also solely dependent on photosynthetic plants for their oxygen requirements.
Explanation:

Snow owls prey on lemmings in their arctic habitat, and their survival is closely linked to the abundance of lemmings. In years when there are many lemmings, snowy owls may raise a dozen babies. How might a scarcity of lemmings affect the snowy owl population?
As you mentioned, the snow owls are linked with the lemmings. This is true of any predator-prey population model. If there aren't many lemmings (prey), then the owl population will go down. This is due to lack of food. The unlucky members will starve and die off. As the predator owl population decreases, the lemming population will go back up. This is because the lemmings aren't being eaten by the predators (as there are less owls to be eating the lemmings). Then as the lemming population goes up, so does the owl population.
As one population goes up, the other does too. This is until they reach the carrying capacity and the populations go down. This cycle repeats itself. It's quite common to find populations in flux all the time like this. Keep in mind that we're only focused on the food aspect and not other factors such as habitat. If the lemming habitat is severely compromised, then that will also affect the lemming population. To keep things relatively simple, we'll assume the habitat stays constant.
Side note: The common misconception is that lemmings jump off cliffs on purpose, and kill themselves, but this is a myth that was unfortunately spread around. Lemmings do not do this. If they did, then the species would have died off long ago.
Why do plants use gravity?
Answer:
Gravity perception is important to plants because they need to send their roots downwards towards water and nutrients and their shoots upwards towards light. Plants are known to detect gravity using statelets, which are small starch-filled packets that settle at the bottom of gravity-sensing cells

Answer:
Genotype Ratio: 1:4
Phenotype Ratio: 1:4
Explanation:
Tt x tt
So, it tells us that for sure the mother has 2 recessive alleles and the father has for sure at least 1 dominant allele and 1 recessive allele (we know this because the offspring can only have a recessive trait if the offspring has 2 recessives, this can only happen if the father has a dominant and a recessive allele). If you put this into the Punnett Square you should find that the probability of Tt is 50% and tt is also 50%.
this would make both the Genotype and the Phenotype 1:4

3) Morphological characteristics of aliens are used to identify them and to name them.
Explanation:
1) The dichotomous keys give you information about the groups that are being differentiated to correctly identify them. All you need to do is follow the description of the organisms and the numbers where each description drives you. If you observed correctly the organism, you will reach the scientific name, or genus, or any other taxonomic group you are looking for.
2) Taxonomy is the study of different organisms, their classification into categories according to their morphological and molecular characteristics and their evolutionary relationships. A binomial name is assigned to each organism, composed of a genus and the epithet.
Among all the categories where organisms are classified, we can find the genus, which includes many species that share some common characteristics that are used to group them together.
In this example, Alienus is the genus of all these aliens species.
3) Morphological characteristics of aliens are used to identify them and to name them.

A 450 kg horse starts a running. If the horse is accelerating at 1.2 m/s2,
which force is closest to the net force acting on the vehicle?*
Answer:
Force of 540 Kgm/s^2 is closest to the net force acting on the vehicle.
Explanation:
Force is the change in momentum per unit time
This relationship is equivalent to product of mass and acceleration
Thus F = Mass * acceleration
Substituting the given values in above equation we get -
F = 450 Kg * 1.2 m/s^2
F = 540 Kgm/s^2

Can someone please give a small description on these words based off of animals cell
Golgi body
Cell membrane
Centrosome
Nucleus
Vacuole
Mitochondrion
Answer:
1.A Golgi body, also known as a Golgi apparatus, is a cell organelle that helps process and package proteins and lipid molecules, especially proteins destined to be exported from the cell.
2.The plasma membrane, or the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell, and that membrane has several different functions. One is to transport nutrients into the cell and also to transport toxic substances out of the cell.
3.The cytocenter or centrosome is a cellular organelle that is not surrounded by a membrane; ... " centrosome- related bodies " (CRBs for centrosome- related bodies) are often seen at ectopic sites.
4.The nucleus is a membrane-bound organelle that contains genetic material (DNA) of eukaryotic organisms. As such, it serves to maintain the integrity of the cell by facilitating transcription and replication processes. It's the largest organelle inside the cell taking up about a tenth of the entire cell volume.
5.A vacuole is a membrane-bound cell organelle. In animal cells, vacuoles are generally small and help sequester waste products.

Most forms of vaccination consist of injecting a person with inactive viruses. How do the proteins from the inactive viruses protect the person from later infections by those viruses?
A. The proteins cause a mild infection that prevents the person’s body from responding to later infections.
B. The proteins bond with receptors on the cells of the person so that later active viruses cannot bind with them.
C. The proteins stimulate an immune response, which produces memory cells that can generate antibodies when new active viruses try to infect cells.
D. The proteins remain in the body and serve as a food source for later active viruses instead of feeding on the person’s tissues and causing the infection.
Answer:
C
Explanation:
Because when you get a vaccine the proteins and bacteria are working against each other so when the doctor says its normal to run a low fever thats why.

Which of these decreases as greenhouse gas pollution increases?
A. Rate of ice-sheet melting
B. Ocean salinity
C. Ocean surface temperature
D. Sea levels
The climate-changing gases present in the atmosphere are greenhouse gases. An increase in greenhouse gas decreases the salinity of the oceans and sea. Thus, option B is correct.
What are greenhouse gases?Greenhouse gases are the major factor contributing to global warming and climate change. They are present in the atmosphere and have increased with a rise in the level of pollution.
The greenhouse gases have an inverse effect on the salinity or the thermohaline circulation. The increased temperature affects the glaciers and results in the melting of the ice caps thereby increasing the water level and surface temperature.
The increased water level and temperature increase the evaporation rate and elimination along with the circulation rate of the water from the poles and equator resulting in decreased salinity.
Therefore, the greenhouse gases decrease salinity.
