Mitochondria evolved from aerobic bacteria while chloroplasts evolved from cyanobacteria.

Mitochondria and chloroplasts likely evolved from engulfed prokaryotes that once lived as independent organisms. A eukaryotic cell engulfed an aerobic prokaryote, which then formed an endosymbiotic relationship with the host eukaryote, gradually developing into a mitochondrion.

Chloroplast evolutionarily derives from a primitive cyanobacteria that was engulfed by non-photosynthetic cells and, progressively, after losing most of its DNA, became the actual chloroplast that retains only a fraction of the original cyanobacterial genes. Chloroplasts of plants and algae are currently believed to originate from a cyanobacterial endosymbiont.

Introduction to Biology: Biomolecules

In the options, they are listing the four more abundant elements in living beings: carbon (C), hydrogen (H), nitrogen (N), and oxygen (O). Given that all of them are essential to forming the molecules found in living beings, we need to check their chemical properties, because they are telling us that is an element that can form long chains.

• Hydrogen, has only 1 electron and can form one bond at a time, so it cannot form long chains

• At normal conditions, ,Oxygen, form molecules of only 2 oxygen atoms (O₂), not long chains.

• Nitrogen, is a similar case to oxygen because at standard temperature and pressure it forms a diatomic gas (N₂)

• Carbon ,has ,4 atoms that can form covalent chemical bonds,, which allows it to form ,polymers, at, standard temperatures.

This means the correct answer is a) carbon.

You can calculate the real size of small objects with the microscope, so in a field, it is important to calculate the diameter.

You may determine the actual size of things that are too tiny to be seen with the eye by measuring the microscope's field of view.

The largest useable field diameter in early microscope objectives typically ranged from 18 millimeters or less, but with a contemporary plan, it can occasionally approach 26 millimeters.

A microscope measurement can be used to classify an object into a certain size group or to determine whether the produced form of a specific feature is within dimensional.

Therefore to find the size of the smallest object in the microscope calculates the diameter of the field.

The Cambrian period. Cambrian explosion, the unparalleled emergence of organisms between 541 million and approximately 530 million years ago at the beginning of the Cambrian Period. The event was characterized by the appearance of many of the major phyla (between 20 and 35) that make up modern animal life.

Answer:Key Points. Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level.

Explanation:

To fill the Punnett Square we must place the alleles from one of the parents horizontally oriented on the top of a 3x3 diagram, and the alleles from the other parent vertically oriented on the left border of the diagram. After that, we must cross each one of the alleles from one parent with the alleles of the other, positioning the result of those crossings (Ee) in the blank space where those alleles meet. Therefore, we must look at the combinations and extract the allele that appears in the same line or in the same column, as follows:

Therefore, the parental genotypes are: EE x ee.

Environmental scientists employ the natural sciences they have learned to save the environment. Natural science expertise is used by environmental specialists to safeguard both the environment and public health. In order to reduce waste, they might collaborate with industry, advise legislators, or clean up contaminated places.

The study on organisms and how they interact with their environment is called ecology.. The interaction between living organisms and their environments is studied by ecologists.

Explanation:

When both double-bond carbons are directly connected to a carbon and a hydrogen, cis-trans can happen. In this instance, a new isomer is produced by switching the substituent on one of the double-bond carbons. Thus, option D is correct.

The molecule must restrict rotation. Each doubly bound carbon atom must have two nonidentical groups.

Molecules with the same atomic connectivity are what the cis isomers are known as. On the same side of the double bond, they stand in for comparable page groups.

Cis-trans isomers display a form of stereo isomerism, in which the atoms are arranged differently in three dimensions.

Therefore, On the other hand, trans isomers are made up of molecules with comparable side groups that are situated on the other side of the double bond.

A recession may be defined as A.6 quarters of declining GDP

Recessions are times of economic collapse that are indicated by rising unemployment, falling stock prices, and a decline in the housing market.

A recession is characterised as a protracted period of real GDP (output) growth that is weak or negative and is accompanied by a considerable increase in the unemployment rate. A recession also weakens a lot of other economic activity indices.

In simple words, a recession occurs when the economy's performance declines over a protracted period of many months, as seen by a reduction in GDP, an increase in the unemployment rate, and decreased consumer expenditure. A recession may have a huge influence on people's daily life.

Dredging by definition is the removal of sediments from the bottom of water bodies such as lakes, rivers, reservoirs, and others, this process is done mainly to maintain the water flow, deth or even increase it, as such is an entirely artificial process, therefore we can say that the correct answer is option A.

Answer:A

Explanation:

All plants need the right temperature, light, water, air, and food to have a proper metabolism and to grow. The height of the plant is directly related to the number of nutrients in the soil and the light for its photosynthetic processes. On the other hand, the lower the number of herbivores, the less likely it is that the branches will be cut and the height of the plant will be reduced.

We can conclude that the correct answer is:

C. Decreased amount of herbivores, increased amount of sunlight.

The fluorescence microscope differs from the compound light, and transmitted light, not so much because of the structure, but instead because of how light is used to generate an image/ see the sample.

In the fluorescence microscope, the light does not go through the sample per se, instead, a filter is needed, it works with a higher wavelength, in this case, the light rays go to the sample and excite the species marked with the fluorescence substance, that is to say, the sample must be previously treated so it can absorb light and re-emitted as fluorescence (electromagnetic radiation) therefore creating an image, of light. This is possible due to the proprieties of some molecules, such as fluorochromes.

The phrase dune erosion by ocean water along a shoreline best describes a density-independent limiting factor that can affect ecosystem stability (Option B).

A density-independent limiting factor can be defined as any factor in a given ecosystem that may alter the homeostasis of the population that lives in a given geographic area.

These factors (density-independent limiting factors) are generally abiotic factors such as hurricanes, extreme temperature conditions, the presence of contaminants in the air that hamper life in a given area, etc.

Conversely, density-dependent limiting factors are biotic factors such as competitive species that alter the development of another population.

Therefore, with this data, we can see that a density-independent limiting factor is any abiotic condition that may alter the life of a population in a give geographic area and thus alter the homeostasis of the whole ecosystem.
