Which of the following types of RNA carries genetic instructions fo building a specific protein?

After a big meal, in those individuals who do not have type i diabetes, the pancreas secretes insulin, which circulates through

chubhunter [2.5K]

This is an example of negative feedback.

After a big meal, glucose levels in the bloodstream increases. The body recognises this change and goes through homeostasis, or the regulation of bodily state or internal environment.

The pancreas secretes insulin, which then binds to insulin receptors. This will result in the uptake of excess glucose from the bloodstream into cells and converted into glycogen to be stored in cells as energy storage molecules.

Since there is the counter effect of body (i.e. when blood-glucose concentration increases, the body sends a signal to decrease the blood-glucose concentration, this is called a negative feedback (instead of a positive feedback, which occurs if for e.g. the body signals cells to increase blood-glucose concentration even after blood-glucose concentration increased after a heavy meal).

Hope this helps! :)

Please help! Match each organism with the correct trophic level it occupies in the food chain.

ale4655 [162]

Blueberry: 1st Trophic Level

Rabbit: 2nd Trophic Level

Snake: 3rd Trophic Level

Cat: 4th Trophic Level

Hope this helps :P

plz give me the brainliest if it does : )

What is the function of the sporangium? question 11 options: a) passes characteristics from one generation to the next b) forms

Ivenika [448]

Answer:

D) Protects the developing mother spore cells

Explanation:

A structure called a sporangium is found in some plants and other creatures and is responsible for producing and storing spores. Spores, which are haploid structures made by organisms, aid in the germination and formation of new organisms.

A structure called a sporangium is found in some plants and other creatures and is responsible for producing and storing spores. Spores, haploid structures produced by organisms, aid in germination and the development of new species. They assist in the process of reproduction, in other words. What does it actually imply that they are haploid, though? Simply said, it indicates that there are just half the chromosomes needed to create a complete diploid creature. The sporangia can divide through mitosis, or cell division, to manufacture and release spores.

A single, potentially complex morphologically produced sporangium is produced by an unbranched sporophyte in mosses, liverworts, and hornworts. The majority of ferns, many lycophytes, and non-vascular plants are homosporous (only one kind of spore is produced). Some ferns, the majority of lycophytes, and some bryophytes are heterosporous (two kinds of spores are produced). These plants generate gametophytes that are functionally male or female, respectively, by the development of microspores and megaspores. Occasionally, two types of spores are generated in the same sporangium and may even form a spore tetrad together.

Microsporangia and megasporangia, two different types of sporangia, are present in the majority of heterosporous plants. All seed plants, as well as a few ferns (Salviniaceae and Marsileaceae), some lycophytes (genera Selaginella and Isoetes, as well as the extinct lepidodendrids), are heterosporous with two types of sporangia.

Sporangia can grow near the terminals of stems, along their sides, or in close proximity to leaves. In ferns, sporangia are often located on the abaxial surface of the leaf, or the underside, where they are tightly grouped into clusters called sori. An indusium, a type of structure, could be present across Sori. The sporangia of certain ferns are dispersed along with the shortened leaf segments or along (or just in from) the leaf edge.

The sporangium has an indirect involvement in sexual reproduction and an active part in asexual reproduction in several phyla of fungus. The sporangium, which has haploid nuclei and cytoplasm, develops on the sporangiophore. Each haploid nucleus and cytoplasm are encased in a hard outer membrane as the spores develop in the sporangiophore. These spores spread by wind during asexual reproduction and develop into haploid hyphae.

Although sexual reproduction in fungus differs between phyla, the sporangium indirectly contributes to sexual reproduction in some fungi. When two haploid hyphae from different individuals combine to produce a zygosporangium in response to adverse circumstances, sexual reproduction takes place in Zygomycota. The zygosporangium's haploid nuclei subsequently combine to form diploid nuclei.

When the environment is more favorable, the zygosporangium germinates, goes through meiosis, and develops into a sporangium that releases spores.

Modify the existing vector's contents, by erasing the element at index 1 (initially 200), then inserting 100 and 102 in the show

Aleonysh [2.5K]

Answer:

Following are the code to this question:

#include <iostream>//defining header file

#include <vector>//defining header file

using namespace std;

void PrintVectors(vector<int> numsList)//defining a method PrintVectors that accept an array

{

int j;//defining integer variable

for (j = 0; j < numsList.size(); ++j)//defining for loop for print array value

{

cout << numsList.at(j) << " ";//print array

}

cout << endl;

}

int main()//defining main method

{

vector<int> numsList;//defining array numsList

numsList.push_back(101);//use push_back method to insert value in array

numsList.push_back(200);//use push_back method to insert value in array

numsList.push_back(103);//use push_back method to insert value in array

numsList.erase(numsList.begin()+1);//use erase method to remove value from array

numsList.insert(numsList.begin(), 100);//use insert method to add value in array

numsList.insert(numsList.begin()+2, 102);//use insert method to add value in array

PrintVectors(numsList);//use PrintVectors method print array value

return 0;

}

Output:

100 101 102 103

Explanation:

In the above-given code, inside the main method an integer array "numList" is defined, that use insert method to insert value and use the erase method to remove value from the array and at the last "PrintVectors" method is called that accepts a "numList" in its parameter. In the "PrintVectors" method, a for loop is declared, that prints the array values.
