Fossil evidence indicates that some dinosaurs had feathers. If birds are indeed descended from dinosaurs, feathers are what kind of character?.

Answers

Answer 1
That would be a physical characteristic.
Answer 2
Feathers would be an analogous character because in this case, it appears that feathers originated in an ancestor of the taxon and they were passed down to birds.

Why are the lysosomes useful during entrapment of particles?

Answers

Answer:

Lysosomes

Explanation:

Lysosomes are membrane-enclosed organelles that contain an array of enzymes capable of breaking down all types of biological polymers—proteins, nucleic acids, carbohydrates, and lipids. Lysosomes function as the digestive system of the cell, serving both to degrade material taken up from outside the cell and to digest obsolete components of the cell itself. In their simplest form, lysosomes are visualized as dense spherical vacuoles, but they can display considerable variation in size and shape as a result of differences in the materials that have been taken up for digestion. Lysosomes thus represent morphologically diverse organelles defined by the common function of degrading intracellular material.

If a deer eats grass, what percentage of energy will the deer acquire from the grass? 0. 1 percent 1 percent 10 percent 100 percent.

Answers

The deer eats grass, the percentage of energy will the deer acquire from the grass will be dependent on the food chain then the accurate solution is 10 percent.

In a food chain, the simplest 10 percent of the strength is transferred from one trophic stage to another. The grass is the manufacturer and the deer is the number one consumer, so, whilst the deer eats the grass, it acquires 10 percent of the entire strength of the grass. Rest strength is dissipated withinside the surroundings thru the metabolic tactics taking location withinside the grass.

What is the position of deer in the food chain?

The 2nd trophic stage includes organisms that consume the producers. These are known as number one purchasers or herbivores. Deer, turtles, and plenty of varieties of birds are herbivores. Secondary purchasers consume the herbivore.

Thus it is clear that 10 percent of energy will the deer acquire from the grass.

During light detection in a photoreceptor, light directly causes what molecular change?.

Answers

During light detection, the light causes a retinal change from cis to trans conformation in regards to the opsin protein.

What is a photoreceptor?

Photoreceptors are the name we use to refer to a specialized form of neuron cells. These cells are crucial in our ability to see, they allow vision. Their job is to receive and interpret light as information. They do this using a protein named opsin, as well as specific conformations of the retina, such as cis or trans, which change with the light.

Therefore, we can confirm that during light detection, the light causes a retinal change from cis to trans conformation in regards to the opsin protein.

What are Heterotrophs known as ?

Answers

Answer:

An organism that doesnt not produce its own food

Explanation:

Heterotrophs are consumers who eat other organisms for food, while autotrophs or producers make food by process of photosynthesis.

Answer:

A heterotroph is an organism that eats other plants or animals for energy and nutrients. The term stems from the Greek words hetero for “other” and trophe for “nourishment.”

Organisms are characterized into two broad categories based upon how they obtain their energy and nutrients: autotrophs and heterotrophs. 

Heterotrophs are known as consumers because they consume producers or other consumers. Dogs, birds, fish, and humans are all examples of heterotrophs.

Heterotrophs occupy the second and third levels in a food chain, a sequence of organisms that provide energy and nutrients for other organisms. Each food chain consists of three trophic levels, which describe an organism’s role in an ecosystem. Occupying the first trophic level are autotrophs, such as plants and algae. Herbivores—organisms that eat plants—occupy the second level. Carnivores (organisms that eat meat) and omnivores (organisms that eat plants and meat) occupy the third level. Both primary (herbivores) and secondary (carnivores and omnivores) consumers are heterotrophs, while primary producers are autotrophs.

A third type of heterotrophic consumer is a detritivore. These organisms obtain food by feeding on the remains of plants and animals as well as fecal matter. Detritivores play an important role in maintaining a healthy ecosystem by recycling waste. Examples of detritivores include fungi, worms, and insects.

Why is carpolestes a prime candidate among plesiadapiforms to be a euprimate ancestor?.

Answers

Answer:

Why is Carpolestes a prime candidate among plesiadapiforms to be a Euprimate ancestor? It had an opposable thumb. It had a nail instead of a claw on its first foot digit.

It had an opposable thumb. Its first foot finger had a nail rather than a claw. Plesiadapiforms were previously thought to be extinct members of the order Primates.

What is the Plesiadapiforms?Carpholites has a two-chambered auditory bulla, like Tarsius, which distinguishes it from early EU primates and all other known Plesiadapiforms.Plesiadapiforms are primitive primates, which means they lacked some primate characteristics while exhibiting others. Plesiadapiforms means "nearly adapiform," and refers to Plesiadapiforms that resemble some adapiforms (or adapoids; later-appearing species).Plesiadapiforms were on a much lower evolutionary stage than modern primates, possibly comparable to living tree-shrews despite sharing some skeleton traits. Plesiadapiforms first appear in the fossil record between 65 and 55 million years ago, though many had become extinct by the Eocene. They were possibly the first mammals to have finger nails instead of claws.
