Answer:

A. Transporting packaged molecules from the Golgi apparatus to be released out of the cell

Explanation:

Activities involving the production of substances like proteins occurs inside a living cell. However, these molecules need to be transported within the cell. Here comes the role of VESICLES. Vesicles are small structures inside a cell that deals with the storage and transport of molecules within the cell.

In this diagram, the small vesicles are transporting molecules from the Golgi apparatus, which is a cellular organnelle that functions in the packaging and modification of molecules like fats, proteins etc. In the diagram, the vesicle is heading towards the plasma membrane, which it will fuse to in order to empty its stored contents out of the cytosol.

irina [24]

Answer:

The correct answer will be option- A and D

Explanation:

<em>E.coli</em> is a bacteria which is pathogenic to humans and<em> E. histolytica</em> is an amoeba which is a parasite.  Both are different species but both are single-celled organism which to survive share feature among them.

The common characters shared by these two species are: they depend on the source of energy for their survival which they usually get from the hosts. Both the species reproduce to produce progenies like them which help them maintain continuity of the species of Earth.

Thus, options- A and D are the correct answer.

Fill in the missing words. naturalselection foundereffect geographicallyisolated species evolution
grandymaker [24]

Hi!


The ancestral finch founded a new population on one of the Hawaiian Islands. Due to the founder effect , allele frequencies of the first small population on one of the islands could have differed from their continental goldfinch-like ancestors. The process of natural selection resulted in adaptation and evolution of the island population into a new species over time. Some of the birds crossed to some of the other islands where they were geographically isolated and evolved into more species occupying different niches.


In terms of population genetics, founder effect is when there is a loss of genetic diversity as a result of the establishment of a new population by a relatively few individuals. Following such an establishment, natural selection is the process  which results in the genes of the fittest individuals of the population being selected over generations. This process ultimately results in evolution, and over time may give rise to new species. Geographical isolation is the physical separation of a population from another owing to geographical changes in the terrain or area. If two populations of the same species are geographically isolated, there is a great chance over time they may evolve into two different species.


Hope this helps!

Explain how the data from your experiments showed that cyanide was used to poison Jared, and that 2-deoxyglucose, arsenic and ol
Aliun [14]

The question is incomplete as the background of the case and symptoms of Jarod is not provided, however, the missing data required for the question is as follows:

Jared was investigating a drug cartel and ate a meal with one of the suspects. After the meal, he had trouble breathing and felt weak and dizzy. Jared may have been poisoned. He is being taken to the CIA hospital for treatment. You are a medical toxologist working for the CIA. It is your job to find out what poison was given to Jared and try to save his life. Patient: Jared Sondheim Age: 32 Occupation: CIA Agent Symptoms: Muscle Weakness Shortness of Breath Dizziness. Jared has arrived at the hospital! It is your job to find out what toxin was used to poison Jared. You can then give him the correct antidote to save Jared's life.

Answer:

Poisning by 2-deoxyglucose syops the glycolysis process which leads to cardiovascular and respiratory symptoms. Due to property of inhibiting the enzyme reqquired for glycolysis, glucokinase. So, there is no ATP production takes place.

Arsenic poisoning inhibits the second stae of cellular respiration, the Krebs cycle which leads to pyruvate accumalation. The symptoms associated with arsenic are diarrhea, sking tone, abdomunal pain, and muscle cramps.

Oligomycin is used as an antibiotic to inhibit proton ATPase present in mitochondria membrane which blocks ATP formation. Watery eyes, cough, congestion in chest and nose are sysmptopms of oligomycin poisining.

The symptoms cyanide poisoning are dizziness, short breath, nd muscle weakness which matches with the symptoms of jarod.

Select the statements that explain why duplication is a driving force for evolution and the generation of new genes.
Paha777 [63]
<span>It is vitally important to life, any form of life. Life in it's self is what we are all striving to grasp, hold and not let escape. It is the endless search for meaning to understand and comprehend. Evolution which is the symphonic struggle of nature to overcome and create the most suitable specimen ensuring its survival within its species from its predators and the world at large. Duplication is natures way to regenerate and strengthen the gene pool of species. It allows newer generations to improve on the genes to enable it to adapt better to the current environment is is facing. It is a constant and never ending process.</span>
