For the first page: These adaptations are advantageous. For example, the dart frog’s bright colors warns predators to stay away from them. This will help them survive because they will not be bothered by any predators. Because the Hosta lives in such a crowded environment it is to its advantage that it has big leaves to get as much sunlight as possible. This makes it more likely to survive than other plants. Both of these advantages help the living thing to be stronger.
For page 2: These adaptations are advantageous. The Toucan has a long and narrow beak that helps it get fruit other birds cannot get. This gives them access to more food which can help them outlive other birds. The Monstera plant has adapted so that it does not mold. This helps it stay healthy whereas other plants may grow mold. These two organisms have adapted so that they have one sure advantage that will help them live longer than other species. The advantages are different but they both serve the same purpose.

If we know myofibrils are made of protein strands, what would expect to find a large number of in the myofibrils themselves.

Answers

Answer:

the Z lines and thick filaments of the myofibrils within the muscle fibers are aligned.

Explanation:

Myofibrils are made up of units that repeat along their length, called sarcomeres.

What is Myofibril what are its myofilaments?

Every muscle cell contains contractile protein filaments of two types: actin and myosin. These myofilaments (or myofibrils) are distinguished from one another by molecular weight, which is higher in the myosin filament.

With this information, we can conclude that myofibrils are made up of units that repeat along their length, called sarcomeres.

Identify the species of horse fossils that would be found in the uppermost layer of rock.

C Hyracotherium
D Miohippus​

Answers

Answer: I think the answer would be D miohippus

Explanation:

Miohippus would be found in the uppermost layer of rock. Therefore, option (B) is correct.

What is Miohippus?

Miohippus is an extinct genus of early horse that lived in North America during the Miocene epoch, around 23 to 5 million years ago. It was a small, three-toed horse that was slightly larger than its predecessor, Mesohippus.

Miohippus had a relatively short face, with a long, narrow skull and teeth that were adapted for grinding tough vegetation. It is believed that Miohippus was the ancestor of the modern horse, and that its evolution was characterized by an increase in size, a reduction in the number of toes, and changes in the shape of the skull and teeth that allowed for a more efficient grazing diet.

A gymnosperm is a plant that has seeds unprotected  by a fruit.

Now, whats a fern?

A fern is a flowerless plant that  has feathery or leafy fronds and reproduces by spores released from the undersides of the fronds.

Okay, now, what makes them different? Ferns are flowerlessFerns do not have seedsFerns are grouped into one divisonFerns have smaller speciesGymnosperms have seeds.Gymnosperms are grouped in  more than one divisonGymnosperms have a larger species.

Now, what do the have in common?They are both vascular They both have sporophyte dominant generation

Some gymnosperm types

cycads. Palm-like plants found mainly in tropical and subtropical regions.ginkgoes: maidenhair tree. One species: Ginkgo biloba; the maidenfern tree no longer living in the wild, and only found in cultivation.gnetophytes: mormon tea, welwitschia, gnetum.conifers: pines, spruces and firs.

Some types of ferns

Here is paragraph form:

Gymnosperms are different because they have seeds and ferns do not. Gymnosperms also have more than one divison.Both gymnosperms and ferns are vascular. They also both have sporophyte dominant generations. So this is what makes them similar and different.

are the benefits of dialysis worth the cost?

Answers

Answer:

The cost of alternative dialysis modalities for the treatment of end-stage renal disease (ESRD) was evaluated, using a societal viewpoint, in a regional nephrology program in south-western Ontario. The dialysis treatments compared were hospital hemodialysis, home hemodialysis, self-care hemodialysis, and continuous ambulatory peritoneal dialysis (CAPD). The participants were all patients treated by the same dialysis modality for the fiscal year April 1990 to March 1991. Fully allocated costs are expressed in 1993 Canadian dollars. The average costs per patient year were $88,585 for hospital hemodialysis, $55,593 for self-care hemodialysis, $44,790 for CAPD, and $32,570 for home hemodialysis. The dialysis treatment costs were $54,929 for hospital hemodialysis, $43,313 for self-care hemodialysis, $31,918 for CAPD, and $26,048 for home hemodialysis. These data quantify the magnitude of the differences between fully-allocated costs among the dialysis modalities in a regional nephrology program in Canada. The methodology used in this economic analysis can be applied to programs which differ in structure and scale. The breakdown of dialysis treatment costs into overhead, support department, personnel, supplies, and medication identifies potential areas for cost reduction strategies.

Living things need energy
Your essay need to include;
producer
consumer
decomposer

Answers

Answer/Explanation:

∴ ║ Living Things Need Energy ║∴

The ability to obtain and use energy is one of the eight characteristics of all living things.  Scientists classify organisms based on how they get their energy: autotrophs or heterotrophs.  Organisms are divided into three main groups- the producers, the consumers and the decomposers.  

Producers get their energy from abiotic factors (non-living sources).  Most producers are plants and get their energy directly from the sun using a process called photosynthesis.  There are also some bacteria that can make their own food from chemicals using a process call chemosynthesis.  Examples of common producers are grasses, trees and flowers.  Algae (which are protists, not plants) are the main producers in aquatic ecosystems. Remember we call these autotrophs because they can make their own food.  

Consumers cannot make their own food.  Instead, they get their energy by eating other organisms.  These are also called heterotrophs.  There are many types of consumers.  Herbivores, such as grasshoppers and prairie dogs, only eat producers.  Carnivores eat animals.  Coyotes, badgers, and falcons are all carnivores.  Organisms that eat both producers and other consumers are known as omnivores.  Most humans are omnivores.  Scavengers are a special type of omnivore.  They eat dead plants and animals.  Vultures and many insects are common scavengers.  

Decomposers are a very special type of heterotroph because they get energy by breaking down dead or dying organisms.  Bacteria and fungi (mushrooms, molds and mildews) are examples of decomposers.  Decomposers are important to ecosystems because they return important nutrients such as water, carbon dioxide and nitrogen to the soil.  Plants then use these nutrients to grow, creating a cycle of nutrients through the ecosystem.        

Each of these organisms depends on the others.  Producers get energy from the sun or chemicals and then give some of this energy to consumers.  The consumers then give some of their energy to the decomposers.  Together, these organisms form a food chain.  A food chain is a series of events in which food energy is transferred from one organism to another.   All food chains have the basic structure of producer  ⇒ primary consumer  ⇒ secondary consumer ⇒ tertiary consumer  ⇒ decomposer.  There are many overlapping food chains in an ecosystem.  These overlapping food chains are known as a food web.  

As energy passes from level to the level in a food chain within a food web, the amount that each organism receives decreases.  For example, in a grassland ecosystem, the grasses get energy needed for life from the sun.  Some of this energy is used by the grass to grow and reproduce.  When a prairie dog eats the grass, it only gets 10% of the energy the grass originally had.  The prairie dog then uses some of the energy from the grass to grow and reproduce.  When a coyote eats the prairie dog, it only gets 10% of the energy the prairie dog originally had.  This decrease in energy at each level of the food chain can be represented by an energy pyramid.
