¿Qué moléculas orgánicas tienen como función formar parte de las membranas celulares?

Answers

Answer:

lípidos (fosfolípidos y colesterol)

Explanation:

Las membranas celulares están formadas principalmente por fosfolípidos, los cuales son lípidos compuestos por una molécula de glicerol con dos ácidos grasos unidos y un grupo fosfato. Los fosfolípidos se disponen formando una bicapa, dentro de la cual los grupos fosfatos (con mayor afinidad por el agua, es decir hidrofílicos) se orientan hacia el exterior celular y hacia el interior de la célula, mientras que las colas de ácidos grasos (hidrofóbicas, por lo que tiene mayor afinidad por sustancias no polares) se encuentran en la parte interna. Además, la membrana posee otro lípido: el colesterol, el cual tiene como principal función la regulación de la fluidez de la membrana.

Which of the following choices
correctly shows the way energy
flows in an ecosystem?
A. Seaweed to Fish to Seal to Polar
Bear to Bacteria
B. Polar Bear to Seal to Fish to
Seaweed to Bacteria
C. Bacteria to Seaweed to Fish to Seal
to Polar Bear
D. Seaweed to Bacteria to Seal to Fish
to Polar Bear

Answers

Answer:

C. Bacteria to Seaweed to Fish to Seal to Polar Bear

Explanation:

Every ecosystem consists of multiple organisms. These organisms feed on each other, forming a food chain. The energy within an ecosystem flows through the food chain.

Here, we're supposed to determine which food chain is the correct one. All organisms can be divided into producers and consumers. Producers are organisms that produce their own food, while consumers feed by consuming other organisms.

The only food chain that makes sense is shown in option C. I wouldn't say that bacteria belong to it as the seaweed is an example of a producer. It doesn't consume other organisms. But, fish feed on it, then seals eat the fish, and polar bears eat the seals. This is why we can safely say that option C is the correct one, despite bacteria being present there. Any other combination wouldn't work as, for example, bacteria (A) and seals (B) can't eat polar bears and the fish can't eat seals (D).

Describe the main molecule found in nucleus and explain how it controls the cells functioning​

Answers

The main molecule found in nucleus is called DNA(deoxyribonucleic acid). This molecule is made of subunits called nucleotides. A nucleotide is made of a nitrogenous base that can be adenine, thymine, guanine or cytosine; a five carbon sugar called deoxyribose and a phosphate group. This molecule controns protein synthesis. Proteins are crucial to the cell's function.

How do police use DNA to try and solve crimes? Do you think city police departments should make their own DNA databases? Explain why or why not. Back up your answer with facts and details from the Article.

Answers

Answer:

Police matches the DNA with the criminal present in their database.

Explanation:

Police use DNA that are collected at the site of crime in order to solve crimes because the criminals DNA are mostly found at the site of crime. the police collected these DNA and search in their database where the DNA of all the criminals are present. if the DNA matches with the criminal present at the database so it  means that this criminal commit this crime so it is arrested and further investigation will be held. Yes, city police departments should make their own DNA databases in order to solve the case quickly.

When chunks of stone fall from a mountainside to the ground below, it is because gravity pulled it down. When a glacier moves through a mountain range, slowly flattening or carving the earths surface in that area, it is because the pull of gravity forces the glacier downhill.

When comparing animal to plant cells, they are different in size, shape, and how they store energy. They have similarities, as well. Which organelles perform similar functions in both plant and animal cells. Group of answer choices D. Ribosome, cell membrane, chloroplast C. Cell membrane, cell wall, nucleus

Answers

Answer:

ribosome, cell membrane, nucleus

Explanation:

The organelles that perform similar functions in both plant and animal cells among the listed organelles would be the ribosome, the cell membrane, and the nucleus.

First of all, chloroplast and cell wall are limited to the plant cell only. Animal cells do not have these organelles.

The ribosome functions as the site of protein synthesis in both plant and animal cells. The cell membrane acts as a channel for the control of the movement of materials in and out of the cells and is found in both plant and animal cells. The nucleus is also present in both cells and serves as the control unit of the cell by housing the genetic materials and dictating how the cells will behave.

Describe the nitrogen cycle. How do organisms obtain nitrogen? (minimum 5 sentences) ILL GIVE BRAINLIEST

Answers

Answer:  Plants, from their roots, suck up nitrogen compounds. These compounds are obtained by animals as they consume plants.

Decomposition is the process by which:
Carbon atoms are released into the soil
Carbon is converted to CO2
Organisms obtain energy by breaking down glucose

Answers

Answer:

Decomposition is the process by which carbon atoms are released into the soil.

Explanation:

Organic decomposition involves the process of degradation of a living organism by releasing its elemental components.

In the process of decomposition, chemical elements such as carbon are released mainly in the soil, contributing to its enrichment and use by other living beings.

The release of carbon —product of decomposition— to the soil, for recycling, is part of the carbon cycle.

The other options are not correct because:

The conversion of carbon into CO₂ is combustion. Organisms obtain energy by breaking down glucose is part of cellular respiration.

Can you think of any organism that make their own food but also eat other organism or their byproducts to survive?

Wheat has flowers similar to those in Fig. 5.1, but reproduces by self-pollination. Explain the consequences of self-pollination for a population of plants.

Answers

Answer:

The transfer of mature pollen grain from anther of the flower to the stigma of the same flower of the same [species  is called self pollination.

Generally, the transfer of pollen grains by wind,animals,and water  to stigmas is called pollination. It is a means of vegetative propagation which ensures reproduction.

Therefore during self pollination, the same genes are distributed  from one generation to another. Thus genetic purity is ensured. It also ensured reproductive success. because there is little chance of the pollen grain getting lost in transit. It is also certain  a particular plant would always breed true.

Additionally it prevent  the process of transfer of genes in some transgenic crops( rice, maize) where through genetic engineering some genes are introduced in their genome.

The only negative effect is lack of genetic diversity. Therefore after a period of time the plants get  weak and prone to diseases and infection. Because of poor resistant from lack of variation.
