describe the subcellular structures that found in all bacteria​

Answers

Answer:

The subcellular structures found in bacteria are: cell wall, cytoplasmic membrane, cytoplasm, ribosomes, vacuoles, plasmids, nucleoid —circular DNA— and annexes, such as pili, cilia and flagella.

Explanation:

Bacteria are unicellular prokaryotic organisms, characterized by a simple structure, lacking a nucleus and most of the organelles, with a circular DNA molecule that is free in the cytoplasm.

The sub-cellular structures present in the bacetry are

Cell wall, surrounding the plasma membrane, composed of peptidoglycan. Plasma membrane of lipidic nature, which covers and protects the cytoplasm.  It is possible to find in some bacteria two plasma membranes.Cytoplasm, lacking endomebrane system. Nucleoid is not a true nucleus with nuclear membrane, but corresponds to circular DNA that is free in cytoplasm. Plasmids are fragments of DNA that are associated with the nucleoid, useful for the exchange of genetic material with other bacteria. Ribosome, which participate in the synthesis of bacterial proteins.Vacuoles are structures that are responsible for the storage of reserve substances, useful for bacterial metabolism. The structures annexes to bacteria are the pili, cilia and flagella. The pili are small villi present on the bacterial surface and participate in the process of intercellular communication and conjugation in prokaryotes. Cilia and bacteria serve for the mobility of bacteria.

How might volcanic eruptions change the flow of energy on earth?

Answers

Answer:

It causes global warming due to emission of carbondioxide gas.

Explanation:

Volcanic eruptions change the flow of energy on earth by emitting gases such as carbondioxide and sulfur dioxide gases. Volcanic gases like sulfur dioxide is responsible for global cooling by reflecting solar radiation back to the space, while on the other hand, carbon dioxide emitted from volcanoes, has the ability to promote global warming by blocking solar radiation. If the amount of carbondioxide gas is higher as compared to sulfur dioxide gas so global warming occurs.

what makes one mineral harder than the other? Explain

Answers

Answer:

The hardness of a mineral is mainly controlled by the strength of the bonding between the atoms and partly by the size of the atoms. It is a measure of the resistance of the mineral to scratching, the Mohs scale is for natural minerals.

Answer:The ones that are tightly bound together look different than do ones with looser bonds. For example, in the illustrations below, (A) shows the atomic structure of carbon in a diamond, and (B) is the carbon arrangement in graphite. (A) is more compact than (B), hence it is harder.

Explanation:Rocks are made of minerals, and different minerals have different crystal structures. The chemical bonds that hold atoms together in these minerals are stronger in some than in others, and the atoms themselves determine which bonds are stronger than others.

Which statement describes how maps represent Earth's surface? They have a three-dimensional surface. They use symbols to represent land features. They all use the same scale to show distance. They accurately represent the relative shape of Earth.

Answers

Answer:

B. They use symbols to represent land features.

Explanation:

In Geography, topography can be defined as the shape and structure of the Earth surface. Thus, a topographic map is used to graphically describe this features.

A topographic map can be defined as an accurate and detailed graphical (two-dimensional) description, representation or records of both natural and man-made (artificial) features on the surface of the Earth.

A topographic map uses contour lines to represent points of equal elevation above sea level such as mountains, hills, plains, valley etc.

The two-dimensional model of a topographic map graphically represents the height of a mount and the steepness of a slope through the use of contour lines.

Contours can be defined imaginary lines used for connecting locations that are having similar elevations on the Earth's surface. These contour lines are typically used for modeling the three-dimensional shape of the Earth surface in a topographic map.

Hence, the statement which best describes how maps represent Earth's surface is that, they use symbols to represent land features.

Answer:

B. They use symbols to represent land features.

Answers

Answer:

1. Individuals in a species vary in characteristics because of differences in their genes.

Individuals will be born with various characteristics due to their genes for instance some people are short and other are tall.

2. Individuals have to compete when resources (such as food)  are limited.

Resources are generally limited so individuals would have to compete t get those resources and survive.

3. Individuals with variations that help them get more of the  resources are more likely to survive.

Some of the characteristics that these individuals have which are different will give them an edge and enable them to get more resources and thus survive.

4. Individuals that survive can pass their genetic variations on to  their offspring.

The individuals that survive will now have offspring and will pass on their genes to their offspring which give give them the same edge their parents had.

5.   Over time, there are more individuals with the variations that  are well adapted to the environment.

Eventually there will be more of those offspring that can adapt as opposed to those who couldn't and keep dying out.

Scientists are looking to determine the primary productivity of a lake by analyzing its oxygen net primary productivity. How are scientists able to measure how much oxygen is used during a plant’s cellular respiration processes?(1 point)

by observing cellular respiration under bright light conditions

by observing cellular respiration only when photosynthesis occurs

by observing cellular respiration by studying biomagnification

by observing cellular respiration under the absence of light

Answers

Question: "Scientists are looking to determine the primary productivity of a lake by analyzing its oxygen net primary productivity. How are scientists able to measure how much oxygen is used during a plant’s cellular respiration processes?"

Answer: "Out of all the options given, the best way for scientists to have the chance to measure the usage of oxygen during a plant's cellular respiration processes would be by 'observing cellular respiration under the absence of light'. So, I would say the best option would be Option D. "

To measure how much oxygen is used during a plant’s cellular respiration processes, scientists did by observing cellular respiration in the absence of light, hence option D is correct.

How to measure oxygen level?

As a result, in the absence of photosynthesis, there would be no glucose or oxygen for respiration, and since photosynthesis requires carbon dioxide, only anaerobic respiration would be possible.

Examining a lake's oxygen net primary production, researchers hope to ascertain the lake's primary productivity. By monitoring the output of oxygen or the intake of carbon dioxide, primary productivity is typically calculated. The standard unit of measurement for production rates is grams of organic carbon per unit area per unit of time.

Therefore, observing cellular respiration in the absence of light.

Describe how an organism's genotypes codes for their phenotype. In your answer use the vocabulary terms: Phenotype, genotype, DNA, mRNA and protein. Please dont answer if you dont know it.

Answers

Answer:

The organism's genotype encodes their phenotype because the genotype corresponds to the characteristic that is determined by genes —formed by fragments of DNA— which are transcribed into mRNA to be translated into amino acid sequences in the synthesis of proteins, determining the morphological and functional characteristics of an organism, that is, its phenotype.

Explanation:

Genotype corresponds to the genetic information contained in the DNA, according to the sequence of nucleotides in its molecular structure. This genotype includes characteristics or polymorphisms that define the appearance and function of living beings.

Each DNA molecule constitutes a chromosome, formed by genes —DNA fragments— each of which determines specific characteristics.

When DNA is transcribed into mRNA, information is being sent that is necessary for the incorporation of amino acids into a protein that is being synthesized. The proteins, in turn, determine morphological and functional characteristics that constitute the phenotype of an individual.
