The digestive tract of the frog is well vascularized because it aids in the absorption of nutrients.
The digestive tract of a frog is a hollow long tube that extends from the mouth to the anus which helps in the ingestion and digestion of food.
The digestive tract of frog has the following characteristics:
alimentary canal of the frog is not long, that is, it is short. It has accessory organs of digestion such as liver, gall bladder and pancreas.All the digested food substances are absorbed at the small intestine due to the presence of microvilli.
This microvilli is made up of a central core that is vascularized, that is, it contains artery, vein and lymphatic capillary.
Therefore, the vascularized microvilli of the small intestine of frog help in the absorption of nutrients.

nucleosomes?
Answer:
Nucleosomes are made up of DNA that's wound around histones
Explanation:
Hope this helps.
Answer:
The nucleosome is the fundamental subunit of chromatin. Each nucleosome is composed of a little less than two turns of DNA wrapped around a set of eight proteins called histones, which are known as a histone octamer. Each histone octamer is composed of two copies each of the histone proteins H2A, H2B, H3, and H4.
membrane molecules that use the energy of atp to move ions against a concentration gradient are called
Membrane molecules that use the energy of ATP to move ions against a concentration gradient are called PUMPS. This type of transport is called active transport.
Active transport is a type of transport that requires energy (e.g, ATP) to move molecules and/or ions against a concentration gradient.
In active transport, specific membrane transporter proteins referred to as pumps are used to move ions against an electrochemical gradient across biological membranes.
These protein pumps are fundamental for creating electrochemical gradients that are subsequently used by cells for diverse purposes (e.g., muscle contraction).

Describe a freshwater biome.
Define a wetland.
Why do wetlands have high biodiversity?
A developer wants to extend a golf course into a wetland. Outline environmental arguments you could make against this plan.
Freshwater biomes are large communities of plants and animals centered around waters with less than 1% salt concentration. They are very important to survival on Earth. Types of freshwater biomes include ponds, lakes, streams, rivers, and even some wetlands. Wetlands are not always considered freshwater biomes because they usually have too high of a salt content.
2.
Wetlands are areas where water covers the soil, or is present either at or near the surface of the soil all year or for varying periods of time during the year.
3.
Wetlands have been called “biological super systems” because they produce great volumes of food that support a remarkable level of biodiversity. In terms of number and variety of species supported, they are as rich as rainforests and coral reefs.

Glands that have branched ducts and secretory cells that form sacs at one end of the ducts are called compound alveolar glands.
What is an exocrine gland?The exocrine gland secretes enzymes outside the gland through the duct. The gland can be unicellular, multicellular, compound, tubular, alveolar, etc. Their modes of functions vary too. An example of an alveolar gland is the mammary gland. Sweet glands are an example of tubular glands.

A species that is naturally rare or that has been depleted to dangerous levels is known, according to the Endangered Species Act, as a(n) ________ species.
Answer:
vulnerable would be the answer
Currently, there are more than 1,300 species in the US that are either endangered or threatened. Species that are in risk of going extinct include those plants and animals that have become so scarce.
What Endangered Species Act, as a vulnerable species?A species that is endangered is one that is in danger of going extinct. The two main factors that cause a species to become endangered are habitat loss and genetic diversity loss.
Natural occurrences may result in habitat loss. For instance, dinosaurs had their home removed some 65 million years ago.
A species that has been designated as vulnerable by the IUCN is one that is predicted to go extinct unless the conditions that jeopardize its existence and reproduction change.
Therefore, A species that is naturally rare or that has been depleted to dangerous levels is known, according to the Endangered Species Act, as a(n)(vulnerable) species.

Making changes to the secondary structure of hair has a different outcome than making changes to its tertiary or quaternary structure. How does this outcome differ
The outcome differs in the way that the protein folds itself at each level. The changes in the way that it folds lead to:
modifications in the function, shape or in the combination with other proteins.
Protein has different levels of structure. Each of them is related to how the amino acids and other molecules interact with each other. Hair is made of proteins, so if one of the structures is affected, the hair is too.
Let's analyse what happens in each level of structure:
In the case of the primary structure, which is the sequence of amino acids, the modification will give a non-functional protein that will not fold into the following structural level. So, there won't be new hair.For the secondary structure, a modification here can lead to a different folding. In other words, it can change from an α helix to a β pleated sheet or the other way round. This will give a different shape to the hair, like curly or straight.A modification in the tertiary structure modifies the interaction of the R groups in the protein, so the three-dimensional structure that this interaction gives will change, giving a different type of hair.Lastly, if we modify the quaternary structure, the protein won't interact with some proteins, but it may interact with others.
In conclusion, the modification of the secondary structure changes the interaction between the elements of the protein giving hair with different shapes.

Although we consume different foods, the parts are eventually used in cellular respiration. Does it matter if they originate from crickets or cows or candy bars?
Given what we know about biological processes, we can confirm that it does not in fact matter where the nutrients come from in terms of cellular respiration.
We consume food to provide the energy we need to function on a daily basis, for this, we may reach for an apple or opt for a candy bar. However, this is irrelevant on a cellular level. Cells do not eat the food the way that we consume them.
They use a process known as cellular respiration to change the food into energy to be used by cells. The most important of this process is the transformation of high-level sugars into simple sugars like glucose and other monosaccharides.

Which of the following most accurately describes what affects Earth's ocean tides?
The Sun and Moon, but the Sun impacts Earth's tides more because it is closer in distance to the Earth.
The Sun and Moon, but the Moon impacts Earth's tides more because it is closer in distance to the Earth.
The Sun and Moon, but the Sun impacts Earth's tides more because it much more massive than the Earth.
The Moon is the only celestial object that influences Earth's ocean tides because it so close in distance to the Earth.
The answer option that most accurately describes what affects Earth's ocean tides is: B. The Sun and Moon, but the Moon impacts Earth's tides more because it is closer in distance to the Earth.
A tide can be defined as the rise and fall of water level in water bodies such as lakes and oceans, especially due to the combined effects of the gravitational force of attraction exerted by the Moon and Sun on planet Earth.
Hence, an ocean tide describes the episodic changes in the height of the surface of an ocean as a result of the gravitational force of attraction exerted by the Moon and Sun on planet Earth.
In conclusion, the Earth's ocean tides is largely affected by the gravitational force of attraction exerted by the Moon than that of the Sun because the Moon is closer in distance to the Earth (approximately 400,000 kilometers).
