please help The Archaeopteryx lithographica fossil shown in the image is the oldest-known fossil with feathers. The fossil shows evidence that the organism had teeth, wings with fingers and claws, and a backbone that extended into a tail. For these reasons, the Archaeopteryx lithographica is considered a transition fossil, meaning that it links and exhibits traits from two different ancestral groups. Use the chart in part B to identify the two animal groups that this fossil links together. Also explain how transition fossils provide evidence for evolution.

Bees are declining at alarming rates in some ecosystems. Which of the following would be a loss of an ecosystem service due to bee declines? The declines in abundance could cause extinctions of bee species or genotypes. Bees pollinate plants, so declines could cause declines in native plant abundances. Bees pollinate many crops, so declines could reduce agricultural production. Bees have many predators, so declines could affect their consumers. Bee declines could cause losses of microbial species not yet known to science.

The declines in abundance could cause extinctions of bee species or genotypes. Bees pollinate plants, so declines could cause declines in native plant abundances.

The genotype of an organism is its complete set of genetic material. Genotype can also be used to refer to the alleles or variants an individual carries in a particular gene or genetic location.

A genotype is a scoring of the type of variant present at a given location (i.e., a locus) in the genome. It can be represented by symbols. For example, BB, Bb, bb could be used to represent a given variant in a gene.

The different types of genotypes are- homozygous recessive (pp), homozygous dominant (PP), and heterozygous (Pp). The homozygous dominant and the heterozygous genotypes show the same phenotypes.

Combustion is an organic material reaction to burning in the presence of oxygen. It is the process of conversion to the carbon cycle.

The earth must sustain its current level of carbon. The carbon cycle keeps this going.

Plants use the carbon from the atmosphere, which is then passed to mammals. Carbon dioxide is released into the atmosphere when animals breathe.

Additionally, after spending a long time in the soil, plants and animals perish and turn into fossil fuels. The carbon dioxide in the atmosphere is then released once they are burned.

Due to the massive amount of fossil fuels burned, a level of carbon dioxide that is above normal is released.

This is causing many respiratory disorders and ocean acidification.

Answer:

based on the temperature of the layers and how far away they are from earth (or any planet with an atmosphere)

Explanation:

the different layers have a series of different temperatures that helps us differentiate them. for example, the farthest atmospheric layer from earth is the hottest because it is closest to the sun, and the layer closest to earth is the coolest because it is farthest from the sun.  

All the countries of the world need to lower their emission rates in order to reduce CFC emissions globally.

CFCs is an acronym for chlorofluorocarbons, a group of non-toxic gases consisting of atoms of chlorine, fluorine, and carbon.

The compounds are found artificially in products like aerosol sprays, old refrigerants, and many other man-made products invented to make life generally better for humans. The gases are considered generally safe and unreactive in lower atmospheres down here.

In the stratosphere, however, CFCs are highly reactive. They undergo photolytic decomposition, a process that is largely catalyzed by the availability of UV light in the stratosphere. When this happens, chlorine molecules are released.

The free chlorine molecules react with the protective ozone layer and as a result, the ozone layer gradually gets destroyed. A single chlorine molecule can react with 100,000 ozone molecules.

Thus, in order to protect the ozone layer by reducing the emission of CFCs, all the countries in the world need to put their hands on deck. The whole world shares a single atmosphere. Thus, CFCs released in one part of the world eventually circulate to every part of the world.

The main disadvantage of fragmentation is the loss of biodiversity. Asexual reproduction is performed by a single parent, and as a result, only its traits, genes, and characteristics are passed down to the next generation organisms.

Fragmentation is a type of asexual reproduction as well as culturing whereby a microbe has been segmented into shards in multi - cellular or colonisation organisms. Each of the fragments gets older in to the mature adults which are exact copies of the original organism.As a result, As habitats fragment, the remaining habitat patches (core areas) may become too small to support species that require a large area to survive. As a result, while some suitable habitat may remain, it may not be large enough to support all of the species associated with that habitat type. Memory blocks are never used.

Without the creation of seeds, asexual reproduction produces new plants. sprouting of new plants. Asexual reproduction of this kind creates new plants from the roots, stems, leaves, and buds. Vegetative propagation refers to reproduction that occurs through a plant's vegetative components. The vegetative components of plants, such as their leaves, roots, stems, and buds, are used for asexual reproduction. Vegetative propagation is what this is known as.

Cell differentiation is the process by which undifferentiated embryonic cells become specialized cells. This happens as a result of a process known as gene expression.

Gene expression refers to the specific combination of genes that are turned on or off (expressed or repressed), and it determines how a cell functions. Gene expression is triggered by signals in your body, both inside and outside of your cells.

Gene expression refers to the process by which information from a gene is used to build the structures of a cell. Because RNA translates and transcribes the DNA code into proteins (cell structures), it also aids in cell differentiation.

Gene expression is a tightly controlled process that allows a cell to respond to changes in its surroundings. It functions as an on/off switch to control when proteins are produced as well as a volume control to increase or decrease the amount of proteins produced.
