compare and contrast the passive and active cellular uptake of glucose molecules and ions
Passive transport does not require energy for the transport of molecules where active transport requires energy for transport.
Active transport VS passive transport A glucose is a large molecule so its diffusion across a membrane is difficult that's why it diffuses across membranes through facilitated diffusion against the concentration gradient.While on the other hand, Active transport is the movement of molecules into or out of a cell through the cell membrane, from a region of lower concentration to a region of higher concentrationso we can conclude that passive transport does not require energy for the transport of molecules where active transport requires energy for transport.Learn more about transport here: https://brainly.com/question/25802833
How is a light element like helium is formed in stars and how is a heavier element like gold formed by stars? YALL HELP ME WITH THIS PLEASE
1. Elements are not formed in stars. All elements were formed during the Big Bang and no elements have been formed since then.
2. Both light and heavy elements are formed only under very high energy conditions, such as a supernova.
3. Only light elements like helium are formed by stars. They are formed from the fusion of hydrogen nuclei. A hydrogen nucleus is made of a single proton. When protons fuse together, a new atom of helium is formed. Heavier elements like gold cannot be formed under any condition.
4. A light element like helium is formed by the fusion of hydrogen nuclei. A hydrogen nucleus is made of a single proton. When protons fuse together, a new atom of helium is formed. Heavier elements like gold form under very high energy conditions, such as a supernova, when helium atoms combine under enough successive collisions to form very heavy elements.
Answer:
its d
Explanation:
lol im pretty sure im right but i could be wrong
The theory behind the formation of helium and gold is the fusing of hydrogen nuclei results in the formation of a light element like helium. One proton makes up the hydrogen nucleus. New helium atoms are created when protons combine. When helium atoms combine through enough consecutive collisions, as occurs during a supernova, they combine to generate heavier metals like gold. The correct option is 4.
What is fusion?
Fusion is a process in which two nuclei combine to form a large, heavier nucleus. This is a nuclear reaction. Nuclear reactions are of two types, fission, and fusion.
Smaller element or lighter elements like hydrogen and helium are formed by the process of nuclear fission, in which the division of element occur from smaller nuclei.
Heavier elements are formed by the process of nuclear fusion. Where lighter elements joined to create heavier elements.
Thus, the correct option is 4.

ANSWER QUCK PLS Why is it important for a cell membrane to be selectively permeable?
Answer:why is it important that the cell membrane is semi permeable? ... The solution around the cell has a lower concentration of solutes and a higher concentration of water than the inside of the cell. The cell gains water and swells. Selective permeability is a property of cellular membranes that only allows certain molecules to enter or exit the cell. This is important for the cell to maintain its internal order irrespective of the changes to the environment. ... Movement across a selectively permeable membrane can occur actively or passively.

Answer:
1. Reaction Formation
2. Denial
3. Regression
4 .Acting Out
5. Dissociation
Explanation:
Answer:
hand-to-hand combat
a gun
heavy object (baseball bat or something like that)
Explanation:
I don't know what situation you mean, but if the person is caught off guard, the first defense mechanism is your own body, punches, kicks, stuff like that
If someone is attacking, there's a 50/50 chance that they will have a gun, in that case, the gun can be used on either side, the attacker or the attacked
If someone is attacking, it is also possible that heavy objects, baseball bats, table legs, pipes, are going to be used on either side.

6. What type of bond does carbon make? How many bonds will one carbon make? Why
is this important in terms of the shape and structure of macromolecules?
Answer:
First answer is covalent bonding
Second answer is 4 bonds. Because carbon has 4 electrons in its outermost shell
Lastly Yes, This allows them to form strong covalent bonds with a number of elements. Carbon can also bond with itself, allowing it to form long chains or rings of carbon atoms
To summarize what you have learned about transcription, explain how a gene directs the synthesis of an mRNA molecule. Include in your explanation the words and phrases: base-pairing rules, complementary nucleotides, DNA, gene, mRNA, nucleotide, nucleus, and RNA polymerase
Answer:
Please find a detailed explanation of the process below
Explanation:
Transcription is the first stage of gene expression in living organisms in which a DNA sequence is used to synthesize a mRNA molecule. This process, which occurs in the NUCLEUS of eukaryotes and cytoplasm of prokaryotes, is catalyzed by an enzyme called RNA POLYMERASE.
- In the initial stage called INITIATION, RNA polymerase binds to the promoter of GENE and starts to unwind the double strand of the DNA sequence.
- The RNA polymerase, then, begins to add complementary NUCLEOTIDE bases following the COMPLEMENTARY BASE PAIRING RULE, which states that Adenine will pair with Thymine (Uracil in RNA) while Guanine will pair with Cytosine i.e. T-A, A-U, G-C etc. This stage is called ELONGATION.
- The last stage called TERMINATION involves the stopping of the process because the RNA polymerase has encountered a termination signal.

explain why cells must divide rather than grow. explain how surface area and volume as well as transport across the cell membrane are related to cell size and homeostasis
Answer:
Cells must divide rather than grow in order to replace damaged cells and reproduce unicellular organisms. The surface area to the volume ratio gets smaller as the cell gets larger. Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume. Along with this, cell transport helps cells maintain homeostasis by keeping conditions within normal ranges inside all of an organism's cells.

The images show the stages of human development. At which stage does cell differentiation start?
Between the eighth and sixteenth weeks of pregnancy, the human fetal pituitary experiences cellular differentiation.
What is cell differentiation ?The process of cell differentiation is how dividing cells alter their phenotypic or functional type. It is likely that all cells originate from stem cells and acquire their functions as they develop. Stem cells are typically at the top of a hierarchical structure that represents cellular composition.
The transformation of a single-celled zygote into a multicellular embryo and then into the complex multisystem of several cell types that is a fetus is an illustration of cell differentiation.
Gene expression and cell differentiation can both be influenced by environmental variables. Available nutrients, salinity, and temperature, for example, are all elements that can alter gene expression in organisms.

A man with a blood genotype IAi marries a woman with a blood genotype IAi. What phenotypes could be expected in their children? 1. Both type A and type O 2. Type O only 3. Type A only 4.Type B only
Answer:
1. Both type A and type O
Explanation:
Blood genotype in humans follow the ABO system. The allele iA (type A) and iB (type B) are co-dominant but both dominant over the allele i (type O). This means that only a human with two i alleles will be type O.
Type A - iAiA or iAi (heterozygous)
Type B - iBiB or iBi (heterozygous)
Type O - ii
In this question, a man with a blood genotype IAi (type A) marries a woman with a blood genotype IAi (type A). Each of the parents will produce a gametes iA and i. Using these gametes in a punnet square (see attached image), offsprings with the following genotype will be produced: iAiA, iAi, and ii.
iAiA and iAi are type A while ii is type O. This means that both type A and type O could be expected in the children of this cross.
