If the emission spectrum of a star is redshifted, it indicates that the star is moving away from Earth, while if it is blueshifted, it indicates that the star is moving towards Earth.

Stars are made up of a combination of different elements, but the most abundant elements found in stars are hydrogen and helium. Hydrogen makes up about 74% of the mass of the Sun, while helium makes up about 24%.

The remaining 2% of the Sun's mass is composed of heavier elements such as oxygen, carbon, neon, iron, and others. The exact composition of a star depends on its mass, age, and evolutionary history.

The emission spectrum of a star can be redshifted or blueshifted depending on the motion of the star relative to the observer (Earth).

If the star is moving away from Earth, the light waves emitted by the star will be stretched out, which causes the wavelength of the light to appear longer than expected. This shift towards the red end of the spectrum is known as redshift.

Conversely, if the star is moving towards Earth, the light waves emitted by the star will be compressed, which causes the wavelength of the light to appear shorter than expected. This shift towards the blue end of the spectrum is known as blueshift.

The options given by Francis Collins to reconcile evolution and faith was in his argument that advances in science present “an opportunity for worship,” rather than a catalyst for doubt.

Francis Collins is known as an American physician-geneticist who discovered the genes associated with a number of diseases and led the Human Genome Project.

Francis Collins believed in seeing God as the creator of the universe – in all of its amazing complexity, diversity and awesome beauty – then science, which is, of course, a means of exploring nature, also becomes a means of exploring God’s creative abilities.

Francis Collins wanted to reconcile faith and evolution, and has been lauded for showing how a religious believer can rise to the highest levels of the scientific establishment while keeping his faith intact and while integrating his faith with his science.

Answer: The cell is the basic unit of life.

Explanation:

Answer:

the answer is C

Explanation:

Sometimes, a single gene can influence many traits in an organism. This is possible due to gene interactions. Thus, the correct option is C.

Genetic interaction is the set of functional association between different genes in an organism. Genetic interactions are the relationship is called as epistasis. Epistasis is the interaction of non-allelic genes where the effect of one gene in an organism is masked by another gene to result either in the suppression of the effect of that gene or they both combine to produce a new trait or character.

In epistasis, the gene which masks another gene is called as epistatic gene, and the gene whose expression is being masked is termed as hypostatic gene. Epistasis is also referred to as the inter-genic or inter-allelic gene interaction.

Therefore, the correct option is C.

Answer:

There is no cartilage but there is epithelium

Explanation:

The pharynx of the human respiratory system does not contain cartilage.

The pharynx,  part of the human respiratory system, is a muscular tube that connects the nasal cavity and mouth to the larynx and esophagus. It serves as a passage for  air and food. The gorge is made up of several regions, each with its own distinctive features.

The nasopharynx, the top part of the throat, contains no cartilage. Instead, it is lined with pseudostratified ciliated  epithelium.This special epithelium helps to trap and transport mucus along with any particles or pathogens in the digestive system for elimination.

These regions also lack cartilage but  are lined with  stratified squamous epithelium. This type of epithelium provides protection from mechanical stress and potential abrasion caused by the passage of food and other substances down the pharynx.

Four groups of microorganisms in nutritional categoyries are: bacteria, algae, protozoa, and viruses

Bacteria feed in a number of ways: Heterotrophic bacterial get their energy through consuming organic carbon. Saprophytic bacterial feed on dead organic material, such as decomposing flesh. Parasitic bacteria kill their host, while others help them.

Protozoa are heterotrophs too and feed on other microorganisms or on organic particles.

Algae feeds on the waste materials produced by decomposing materials and the waste of marine animals.

There are some microbial life that can indeed exist in the complete absence of sunlight or organic nutrients but there are also some that cannot.

There are bacteria that live in hot springs and other volcanic water that get their energy from chemicals released as a result of volcanic activity.

The bacteria's DNA polymerase is very stable at high temperatures, which means it can withstand the temperatures needed to break the strands of DNA apart in the denaturing stage of PCR

The whole process of forming ATP from the electron transport chain is known as oxidative phosphorylation. Electrons carried by NADH + H+ and FADH2 are transferred to oxygen via a series of electron carriers, and ATPs are formed. Three ATPs are formed from each NADH + H+, and two ATPs are formed for each FADH2 in eukaryotes.

The amount of organic material which is available for transfer to the next trophic level after subtracting material used for respiration is known as Net primary productivity. Thus, the correct option is C.

Net primary production is the biomass which provides the energy for all the heterotrophic activities in an organism. Consumers who capture the energy stored within the organic molecules of their food sources such as carbohydrates. Therefore, each of the trophic level acquires the energy which is represented by the biomass consumed by that organism from the lower trophic level.

Net primary production (NPP) is the amount of biomass or the carbon produced by primary producers of the food chain per unit area and time, obtained through subtracting plant respiratory costs (RP) from gross primary productivity (GPP) or the total photosynthesis.

Dormancy comes in two forms: seed coat dormancy and embryo dormancy

Answer:Plants that reproduce by seeds. Seed plants have special structures on them where male and female cells join together through a process called fertilisation. After fertilisation, a tiny plant called an embryo is formed inside a seed.

The statement that would correctly explains the weight you would experience on each planet is You would weigh less on planet A because it has less mass than planet B. Option D

Weight is the force experienced by an object or person due to gravity. Since it is as a result of gravitational force, it depnds on both the mass of the objct or person and the level of gravity of the planet.

Gravity is dependent on th mass of the planet, and if planet A has lesser the mass of planet B, its gravitational force will be most likly be weaker.

This therefore means a person is going to weigh less on planet A than on planet B, even though both planets have the same size.
