Answer:
3.Golgi apparatus, because n packages proteins received from the ER
Explanation:
1. Mitochondria, because they rely on the ER as an energy source - this is false. The mitochondria are the energy-producing organelles in the cell. They do not rely on the ER for energy
2.Ribosomes, because they receive proteins made by the ER - this is false, the ribosomes are the protein synthesis factories of the cell. Some of them are even attached to the ER
3.Golgi apparatus, because n packages proteins received from the ER - this is true. The ER is involved in folding and modifying proteins, which are passed to the Golgi for further modification and transport.
4.Cytoplasm, because it relies on the ER for structural support - this is false, structural support is provided by the cytoskeleton

In what order do the electrons move through the electron transport chain?
Answer:
Four Stages: Glycolysis (a transition reaction that forms acetyl coenzyme) A, the citric acid (Krebs) cycle electron transport chain, and chemiosmosis.
Explanation:
The flow of electrons through the components of the electron transport chain occurs in order of increasing reduction potential.
Electronic transport chain is the set of enzymatic complexes embedded in the mitochondrial membrane that oxidize NADH and FADH2, generating a proton gradient.
It basically comprises 2 processes:.
1) Electrons are transported across the membrane, from one carrier protein complex to another.
2) Protons are translocated through the membrane, which means that they are passed from the interior or mitochondrial matrix to the intermembrane space causing a proton gradient.
Oxygen is the final acceptor of the electron, combining with them and the H ion to produce water.
This chain comprises numerous associated components in the form of enzyme complexes, each of which has transmembrane proteins that support the complex on the inner mitochondrial membrane, an Fe-S flavoprotein, ubiquinone, and the cytochrome chain.
The electrons start out in order with very high energy, which they lose as they pass through the chain. In other words, the carrier molecules are reduced and oxidized, lowering electrons from high energy levels to lower ones.
Therefore, we can conclude that the flow of electrons through the components of the electron transport chain is carried out in order from high energy levels to lower ones.

(Q005) Humans are unusual because our cultural practices can actually change our environmental circumstances. We can change the environment in which natural selection acts on our traits. Describe how this process has played out in the evolution of adult lactose tolerance. Can you hypothesize any similar situations where our future evolution may be influenced by cultural practices we have today
Answer:
Lactose tolerance conferred an evolutionary advantage, thereby this beneficial mutation increased its frequency in the population
Explanation:
Originally, adults were unable to digest lactose. But approximately 8,000-10,000 years ago something remarkable happened: a mutation near the gene that produces the lactase enzyme appeared in a raising cattle population from Europe-Middle East, making adults able to digest lactose. Nowadays, many adults from different societies are tolerant to digest lactose because this mutation increased its frequency and extended to different populations. It is a classical example of how a beneficial mutation may eventually become the most common gene variant by increasing its frequency in the population, and, subsequently extending to other populations. It is possible to hypothesize that new mutations associated with human activities may appear in current human societies, thereby conferring an evolutionary advantage in the same way that lactose tolerance in cattle-raising people. For example, nowadays, mutations in human behavior-associated genes might confer beneficial social skills (thereby increasing the frequencies across time or across populations).

Which of the following statements correctly describes some aspect of protein excretion in prokaryotic cells? a Prokaryotes are unlikely to be able to excrete proteins because they lack an endomembrane system. b The mechanism of protein excretion in prokaryotes is probably the same as that in eukaryotes. c Proteins that are excreted by prokaryotes are synthesized on ribosomes that are bound to the cytoplasmic surface of the plasma membrane. d In prokaryotes, the ribosomes that are used for the synthesis of secreted proteins are located outside of the cell. e Prokaryotes contain large pores in their plasma membrane that permit the movement of proteins out of the cell.
Answer:
The correct answer is option c "Proteins that are excreted by prokaryotes are synthesized on ribosomes that are bound to the cytoplasmic surface of the plasma membrane".
Explanation:
Many prokaryotes secrete proteins, particularly, extracellular enzymes that have a function outside the cells and toxins that are not needed by the cell. As any other protein, proteins that are excreted by prokaryotes are synthesized on ribosomes that are bound to the cytoplasmic surface of the plasma membrane. However, excreted proteins go to the general secretion (Sec) pathway, where they are tagged and further processed.

C. 10 ul of 1 mg/ml BSA is mixed with 990 ul TBS.
D. 10 ul of 0.1 mg/ml BSA is mixed with 990 ul TBS.
Answer:
A. [tex]C_2=1.5\frac{mg}{mL}[/tex]
B. [tex]C_2=0.075\frac{mg}{mL}[/tex]
C. [tex]C_2=0.01\frac{mg}{mL}[/tex]
D. [tex]C_2=0.001\frac{mg}{mL}[/tex]
Explanation:
Hello.
In this case, we must compute the final concentration in all the cases so we solve for it in the given equation:
[tex]C_2=\frac{C_1V_1}{V_2}[/tex]
Thus, we proceed as follows:
A. Here, the final diluted solution includes the 300 μL of the 5 mg/ml-BSA and the 700 μL of TBS.
[tex]C_2=\frac{300\mu L*5\frac{mg}{mL} }{(300+700)\mu L}\\\\C_2=1.5\frac{mg}{mL}[/tex]
B. Here, the final diluted solution includes the 50 μL of the 1.5 mg/ml-BSA, the 450 μL of water and the 500 μL of TBS.
[tex]C_2=\frac{50\mu L*1.5\frac{mg}{mL} }{(50+450+500)\mu L}\\\\C_2=0.075\frac{mg}{mL}[/tex]
C. Here, the final diluted solution includes the 10 μL of the 1 mg/ml-BSA and the 990 μL of TBS.
[tex]C_2=\frac{10\mu L*1\frac{mg}{mL} }{(10+990)\mu L}\\\\C_2=0.01\frac{mg}{mL}[/tex]
D. Here, the final diluted solution includes the 10 μL of the 0.1 mg/ml-BSA and the 990 μL of TBS.

1. What did Linnaeus use to classify living things?
Answer:
Perhaps the single greatest contribution Linnaeus made to science was his method of naming species. This method, called binomial nomenclature, gives each species a unique, two-word Latin name consisting of the genus name and the species name. An example is Homo sapiens, the two-word Latin name for humans.
Explanation:
Can I have brainliest
It is from Google
Binomial nomenclature, which Carolus Linnaeus created, is a system for categorizing living things. Linnaeus was a Swedish botanist and biologist.
Binomial nomenclature is a biological system for naming organisms.
It is quite difficult to identify an organism internationally and keep track of the number of species when it has multiple local names.
Some of the features of binomial nomenclature that Linnaeus used to classify living things are:
Latin names are used because they are universal and consistent.
The process of naming each organism uniquely using the two words "genus" and "species."
The arranging of living things into a hierarchy, with each organism being given a position based on how similar it is to others.
Humans, for instance, are known as Homo sapiens. Its name, Homo, translates to "man" in Latin. The name of the species, sapiens, means "wise".
Therefore, Binomial nomenclature is used by Linnaeus to classify living beings.
