what are osmosis..in 50 words ​

Answers

Answer 1
osmosis:

Osmosis is a passive process and happens without any expenditure of energy. It involves the movement of molecules from a region of higher concentration to lower concentration until the concentrations become equal on either side of the membrane.

Any solvent can undergo the process of osmosis including gases and supercritical liquids.

Let us have a detailed look at the different types and effects of osmosis in detail.

Answer 2

Osmosis, the spontaneous passage or diffusion of water or other solvents through a semipermeable membrane (one that blocks the passage of dissolved substances—i.e., solutes). The process, important in biology, was first thoroughly studied in 1877 by a German plant physiologist, Wilhelm Pfeffer. Earlier workers had made less accurate studies of leaky membranes (e.g., animal bladders) and the passage through them in opposite directions of water and escaping substances.

A student is presented with a model of a digestive system and is asked to remove one structure (small or large organ) that will have the largest impact on decreasing chemical digestion. Which structure should the student remove

Answers

Answer:

Small intestine

Explanation:

Digestion is the process of breaking down food molecules into simpler and usable forms by the body cells. The process of digestion involved the mechanical aspect and chemical aspect. The mechanical one deals with using physical means like chewing to break down the food particles.

However, the chemical one deals with the usage of chemically-secreted enzymes to work on the food molecules. Lots of digestive organs are involved in this chemical digestion, but, the most of chemical digestion takes place in the SMALL INTESTINE. The small intestine is where most of the chemical digestion occurs including absorption.

Hence, according to this question, the student should remove the SMALL INTESTINE because it will have the largest impact on decreasing chemical digestion.

a. Position of geese flying in V formation
b. Color and shape camouflage of praying mantis
c. Muscle atrophy in aging dogs
d. Male dominance in a pack of wolves

Answers

i think the answer would be B, because the color and shape is a trait/characteristic that will improve its survival chances

The color and shape camouflage of praying mantises is an example of an heritable trait possessed by an animal that will improve its reproductive ability and survivability in its environment. So, the correct option is (B).

What are Traits?

A phenotypic trait is defined as a specific type of a phenotypic characteristic of an organism that can be either inherited or environmentally determined, but usually occurs as a combination of both.

These are characteristics or features of an organism that are expressed by genes and/or influenced by the environment including physical properties of the organism such as hair color, leaf shape, size, etc., and behavioral characteristics such as bird nests.

The color and shape camouflage of praying mantises is an example of an heritable trait. Thus, the correct option is (B).

Which process is identified by number 1 in the diagram and where in the cell does this process occur?
DNA
mRNA
Protein
1
2
O replication; during the cell cycle
O transcription; in the nucleus of the cell
translation; at the ribosome
transcription; at the ribosome

Answers

Correct answer - Translation, at ribosome.

Why? - In molecular biology and genetics, translation is the process in which ribosomes in the cytoplasm or endoplasmic reticulum synthesize proteins after the process of transcription of DNA to RNA in the cell's nucleus. The entire process is called gene expression.

The process is identified by number 1 in the diagram and where in the cell does this process occur is translation, at the ribosome. Thus option 3 is correct.

What is translation?

Translation is defined as the process by which a messenger RNA (mRNA) molecule's sequence is converted into an amino acid sequence during protein synthesis.

It is also be defined as when DNA is converted to RNA in the cell's nucleus, the process through which ribosomes in the cytoplasm or endoplasmic reticulum synthesize proteins. Gene expression refers to the entire process.

Initiation, elongation, and termination are the three phases of an mRNA molecule's translation by the ribosome.

Thus, the process is identified by number 1 in the diagram and where in the cell does this process occur is translation, at the ribosome. Thus option 3 is correct.

Weak hydrogen bonds between the nitrogenous base pairs hold the two strands of DNA together. Why are the strands held together by weak hydrogen bonds instead of covalent bonds

Answers

Answer:

Explanation:

Hydrogen bonding is usually occur wen interaction with hydrogen atoms occur.

Hydrogen bonds joins DNA polymers because an hydrogen atom occur on on one base which is called hydrogen bond donors and another oxygen or nitrogen atoms on the base across from it which is called hydrogen bond acceptors.

Adenine “A” a purine and Thymine “T” a pyrimidine each have a donor and one acceptor, whereas Cytosine “C” a pyrimidine has one donor and two acceptors, and Guanine “G” a purine has one acceptor and two donors.

This atoms allows for hydrogen bond between them that gives them structure of DNA molecule.

A nucleotides is hydrogen bonded to T nucleotides while C nucleotides is hydrogen bonded to G nucleotide this is called complementary base pairing.

A lichen is an organism that structurally appears to be a single organism. But a lichen is actually two different organisms—a fungus and green algae—living together as one organism. The fungal partner derives its nutrition from the photosynthesizing algae. How does a lichen differ in its photosynthetic activity from Elysia chlorotica, the sea slug that’s considered to be a photosynthesizing animal?
A.
In lichens, the fungi photosynthesize on their own, while Elysia chlorotica forms a relationship with a photosynthesizing plant.
B.
In lichens, the relationship with the algae lasts throughout the life cycle, but in Elysia chlorotica, the relationship occurs only during the immature juvenile stage of the slug’s life cycle.
C.
Lichens can photosynthesize only because of the living algal partner, while Elysia chlorotica incorporates chloroplasts from algae into its cells.
D.
In lichens, the association between the fungi and algae is permanent, while Elysia chlorotica associates with a photosynthesizing organism only when it requires food.

Answers

Answer:

B. Cycle

Explanation:

Lichen performs photosynthesis with the assistance of an algal partner, but Elysia chlorotica incorporates the chloroplast from an algal partner, which is how lichens vary from Elysia chlorotica in this regard,  hence option C is correct.

How does lichen photosynthesize?

A process known as photosynthesis is one in which green plants and some photosynthetic algae produce their own food, glucose, using carbon dioxide and water in the presence of light.

Lichen is a symbiotic association between an algal component that produces food and a dominant partner fungus that gives the lichen its thallus form and fruiting bodies. A particular species of mollusc called Elysia chlorotica uses the chloroplast of an algal partner to carry out the photosynthesis process.

Therefore, Lichens can photosynthesize only because of the living algal partner, while Elysia chlorotica incorporates chloroplasts from algae into its cells, hence option C is correct.

Need help plz!!! Trying to catch up on biology anything can help!!!!

Answers

Answer:

See the answer below

Explanation:

The control group in an experimental study is the subject group that is not administered the treatment variable. The control group forms the baseline for comparing the effects produced by the treatment variable on the experimental group.

Thus, in this case, the control group would be the 10 mice that were not exposed to the radio waves.

The independent or the manipulated variable, in this case, is the exposure or otherwise of the mice to the radio waves.

The dependent variable is the actual variable that is going to be measured, otherwise known as the effect variable. In this case, the dependent variable would be the strength of the mice measured by their ability to push the block of wood blocking their food.

Since 8 out 10 mice and 7 out of 10 mice were able to push the wooden block in both the experimental and the control group, Bart's conclusion should reject the hypothesis that the radio waves make mice extra strong.

Bart's experiment can be improved by increasing the number of subject mice in each group. The more the number of subjects, the more the accuracy of the outcome would be.

Some genes are important enough to be called "molecular switch" or "master" genes. What is the purpose of these genes?

A. They control when other genes are expressed
B. They determine the organization of the genome
C. They regulate cell metabolism
D. They modulate the rate of translation

Answers

Answer:

Genes called "molecular switch" or master genes have the purpose of control when other genes are expressed (option A).

Explanation:

Master gene is so named because it has the function of controlling the behavior of other genes, organizing their functions and regulating when they can be expressed.

The name of molecular switch is synonymous with the master gene, since its activation determines the genetic regulation necessary to establish cell differentiation and even the determination of the sex of some species.

The other options are not correct because:

    B. Master genes do not determine the organization of the genome .

    C. Regulation of cell metabolism depends of substances as hormones and enzymes.

    D. The rate of translation does not depend on the activity of master genes.

In 1520, the Spanish conquistador Hernn Corts wrote to Spanish King Charles V from the Aztec city of Tenochtitlan inwhat is now Mexico. Read the following excerpt from his letter. Then answer the questions based on the excerpt.This great city contains a large number of temples, or houses, for their idols, very handsome [buildings]... theprincipal ones religious persons of each particular sect are constantly residing, for whose use, besides the housescontaining the idols, there are other convenient habitations. ... Among these temples there is one which farsurpasses all the rest, whose grandeur of architectural details no human tongue is able to describe; for within itsprecincts, surrounded by a lofty wall, there is room enough for a town of five hundred families. ... There are fullyforty towers, which are lofty and well built, the largest of which has fifty steps leading to its main body, and is higherthan the tower of the principal tower of the church at Seville. The stone and wood of which they are constructed areso well wrought in every part, that nothing could be better done, for the interior of the chapels containing the idolsconsists of curious imagery, wrought in stone, with plaster ceilings, and wood-work carved in relief, and painted withfigures of monsters and other objects.Three halls are in this grand temple, which contain the principal idols; these are of wonderful extent and height, andadmirable workmanship, adorned with figures sculptured in stone and wood; leading from the halls are chapels withvery small doors, to which the light is not admitted, nor are any persons except the priests, and not all of them. Inthese chapels are the images of idols, although, as I have before said, many of them are also found on the outside; theprincipal ones, in which the people have greatest faith and confidence, I precipitated from their pedestals, and castthem down the steps of the temple, purifying the chapels in which they had stood, as they were all polluted withhuman blood, shed ill the sacrifices. In the place of these I put images of Our Lady and the Saints, which excited not alittle feeling in Moctezuma and the inhabitants, who at first (protested], declaring that if my proceedings were knownthroughout the country, the people would rise against me; for they believed that their idols bestowed on them alltemporal good, and if they permitted them to be ill-treated, they would be angry and without their gifts, and by thismeans the people would be deprived of the fruits of the earth and perish with famine. I answered, through theinterpreters, that they were deceived in expecting any favors from idols, the work of their own hands, formed ofunclean things, and that they must learn there was but one God, the universal Lord of all, who had created theheavens and earth, and all things else, and had made them and us... and they were bound to adore and believe Him,and no other creature or thing.I said everything to them I could to divert them from their idolatries, and draw them to a knowledge of God our Lord.... Afterwards, Moctezuma and many of the principal citizens remained with me until I had removed the idols, purifiedthe chapels, and placed the images in them, manifesting apparent pleasure; and I forbade them sacrificing humanbeings to their idols as they had been accustomed to do; because, besides being abhorrent in the sight of God, yoursacred Majesty had prohibited it by law, and commanded to put to death whoever should take the life of another.Thus, from that time, they refrained from the practice, and during the whole period of my abode in that city, theywere never seen to kill or sacrifice a human being.Part AWhat is Corts describing in this passage?
