How would you change your model to show what happens when other cell receives the protein
Answer:the protein to enter the cell the molecular size should be small to pass the cell membrane because it is selective membrane.
But if it is cell wall it is fully permable so it can pass easily and enter to the cell membrane which is selective membrane
Toxoplasma is a protist that must infect cats to be able to reproduce. The infection doesn’t benefit cats and only rarely harms them. What type of symbiotic relationship is this, and why?
Answer:
The correct answer is : parasitism.
Explanation:
Parasitism is a symbiosis relationship in which two organism lives together but only one is benefited and other harm in any means. Toxoplasma is, in this case, parasite which is benefited while cats are host and harmed in this relationship.
Degree and chances of harm or benefit do not defines the symbiosis relationship between two organism. Cats are rarely harmed but still harmed in this relationship.
Thus, the correct answer is : parasitism.
Answer: Parasitism
Explanation: There is no benefit to the cat and there is only a benefit to the toxoplasma.
Which of these is a pure substance

Which statement best describes the limits of science?
O A. Science cannot answer philosophical questions.
O B. When used properly, science can answer all questions.
O.C. Science can usually answer only mathematical questions.
D. Science cannot answer any difficult questions.
Answer:
A. Science cannot answer philosophical questions.
Explanation:
Because at least some philosophical problems are not real problems. Instead of a language disease, the solution is not solved by scientific means, but by standardizing the use of language and slenderness. For people who are obsessed with philosophical questions, no scientific explanation can convince them.
a) Antonie Van Leeuwenhoek is considered to be the first microbiologist. His work was completed before Pasteur's. He was the first to use microcscopes to observe and describe single-celled organisms, which he originally referred to as animalcules, and which we now refer to as microorganisms. How did Van Leeuwenhoek's work provide the basis for Pasteur’s work on disproving the theory of spontaneous generation? (4 points)
Answer:
Explanation:
The spontenous genrration theory states that living organisms can be spwan without descent of similar organisms; so in other words, it is possible for living creatures could arise from nonliving matter such as water. Similarily in 1676 Van Leeuwenhoek discovered tiny organisms living in his cup of water- the first bacteria observed by man. Pasteur's spontenous generation theory came into the limelight after his most noteable experiment in 1859; in which he boiled meat broth in down ward tipped flasks. It is importnat to note that the tip of the flask (the neck) is what prevented particles to fall freely and instead the bent neck allowed air to travel through the flask- if the flask were to be tilted on its side the particles would seep into the broth and create a cloud within the flask. Pastuer further decided to boil the broth to possible create bacietia. Boiling the broth exposed the contents to air vessels which contained a filter to stop the particles from seeping thorugh into the broth. What Pastueru concurred from his experminet was that flasks with filters and no filters that did not allow the particles to pass into the medium of the flask, were unsucessful with createing bacteria life. Thus, Pasteur found that noithing grew in the flasks unless they were broke open, disapproving that living organisms could be spotenously generated within the broth, was instead created from outside the inards of the flask- and were created as spores or dust.
during meiosis, a single male germ cell will produce ______ sperm, whereas a single female germ cell will produce _____ egg.
Answer:
The correct answer is : 4 sperms, and 1 egg.
Explanation:
Germ cells are the cells that have ability to divides in to gametes that will fused with the gametes of opposite sex to reproduce sexually and produce offspring.
Meiosis is one of the cell division process where one cell goes under the division twice to make four cells with the half of the genetic content than the parent cells. These cells are gametes or sex cells known as sperm in males, eggs in females.
In this process germ cells go under division twice to produce four daughter cells that are haploid, in males these cells are called as sperms, whereas in females the three cells become polar bodies and the fourth cell termed as egg.
Thus, the correct answer is : 4, and 1.

Why woman's have big hips? what are the advantages & disadvantages of having big hips?
Answer:
Women have wide hips or big hips in order to be prepared for the childbirth and permitting pregnancy. The size of the hips of the women starts to wide during puberty as hips bone widens due to the estrogen that leads to increase in size of pelvis.
Advantages of big hips in women:
Besides the sexual attraction widen or big hips are the essential for the physical support and helps in conceiving pregnancy and permitting childbirth. It is also helps in advantage of store fat.
There are not enough significant disadvantages of wide hips other than physical and sexual challenges.
Explain how energy flows through the trophic levels
Answer:
through an ecosystem
Explanation:
The amount of energy at each trophic level decreases as it moves through an ecosystem. As little as 10 percent of the energy at any trophic level is transferred to the next level; the rest is lost largely through metabolic processes as heat.

A learner was walking along a road when she saw an object under a tree. When the learner touched the object, it rolled over and divided into two . Which characteristics of living organisms did the object show?
Answer:
growth, reproduction, and sensitivity
Explanation:
The characteristics of living organisms displayed by the object are growth, reproduction, and sensitivity.
When the organism reacted by rolling over in response to touch from the learner, it was displaying sensitivity. Sensitivity has to do with the ability of living organisms to be sensitive to things such as touches.
When the object divided, it was displaying growth and reproduction that are characteristics of living organisms. Growth can be defined in this case as an irreversible increase in the number of cells and reproduction can be defined as the production of new individuals.
By dividing into 2, the object has increased its number of cells and has also produced a new individual.
Hence, the characteristics of living organisms shown by the object are growth, reproduction, and sensitivity
Provide a food web for Grassland starting with the Earth's primary source of energy.
Answer:
Sun energy >>> Grass >>> Mouse >>> Fox >>> Puma/Mountain Lion>>>Microorganisms.
Explanation:
Organisms that can synthesize inorganic substances, such as light, and turn it into food according to their own needs are producers, and they are called autotrophic organisms. These organisms are by excellence all plants, that photosynthesize. Organisms that are incapable of producing their food are called heterotrophic. They depend on other organisms from the trophic chain such as plants or other animals to feed on, so they can get proteins and energy. In the trophic chain, heterotrophic organisms occupy the first, second, or third consumer level, after producers.
The trophic web is the process of energy transference through a series of organisms, in which every organism feeds on the preceding one and becomes food for the next one. The first link is an autotroph organism or producer, such as a vegetable, that can synthesize organic matter from inorganic matter. The next links are the consumers: herbivores are primary consumers and feed on producers. Carnivores are secondary consumers and feed on herbivores, and so on. The last links are the decomposers, microorganisms that act on dead animals degrading organic matter.
In the exposed example of a food web for Grassland, we can differentiate:
Producer: Grass. An autotrophic organism that synthesizes organic matter from the sun energy. These species reproduce sexually and produce seeds for dispersion. These seeds are also an important source of food for many animals.Herbivores (Primary consumer): Mouse. A heterotrophic animal that feeds on the seeds of the grasses. Carnivore (Secondary consumer): Fox. A carnivore heterotrophic animal that hunts mouses and feeds on them.Carnivore (Tertiary or superior consumer): Puma/Mountain lion. A superior consumer, carnivore heterotrophic animal that hunts foxes and feeds on them.Decomposers: Microorganisms. When the puma dies, these organisms degrade the animal´s organic matterHELP!!!

List the energy transformations from the sun until energy is lost
Answer:
Chemical Energy - Mechanical Energy and Heat
Explanation:
The energy that is in the sunlight gets absorbed by plants and gets turned into chemical energy by photosynthesis.
Than this energy is transferred to animals who eat the plants as chemical energy.
Lastly the ATP that contain the chemical energy gets burned in the cells and gets turned into mechanical energy and heat-loss to the environment.
I hope this answer helps.

A strain of Streptococcus pneumoniae is no longer able to synthesize its capsular polysaccharide. What is a likely outcome?
a. It will no longer be motile
b. It will not be able to appropriately transport ions across its plasma membrane
c. It will produce more potent toxins which damage the host
d. It will no longer be able to carry out fermentation
e. It will be readily phagocytized upon entering the host
Answer:
e. It will be readily phagocytized upon entering the host
Explanation:
Streptococcus pneumoniae is a Gram-positive bacteria of the genus Streptococcus, being this pathogen known to produce respiratory tract infections and one of the most important causes of meningitis and pneumonia. The capsular polysaccharide of S. pneumoniae is required for its virulence. Based on capsule virulence factors, S. pneumoniae can be classified into 90 distinct serotypes, but only a few serotypes are able to produce serious diseases. The virulence factors localized in the capsule include invasins and adhesins, which act as antiphagocytic and immunogenic factors, respectively.
