Examine the physical characteristics of the frog and determine if it is a vertebrate or an invertebrate. Be sure to justify your answer.

Answers

Answer 1

A vertebrate is an animal which has a series of nerves running down from its brain to its back and are covered by special bones. These bones are called as vertebrae make up the spine which protects the nerves and provides the animals a wide range of motion.

Frogs are classified as amphibians and live in forest areas near water bodies and are different from reptiles as they lay eggs in water and not on land.

The physical characteristics of frogs classify them as vertebrates as they possess a full skeletal structure including the spinal cord.

Answer 2

Final answer:

A frog is a vertebrate due to its internal skeletal structure that includes a spine with ten vertebrae, which is characteristic of vertebrates. As a member of Amphibia capable of breathing through lungs as adults and possessing a complex nervous system, it fits within the broader classification of vertebrates.

Explanation:

Based on the physical characteristics described, a frog is a vertebrate. Vertebrae are the series of bones that make up the vertebral column or backbone, which is a definitive characteristic of vertebrates. Frogs have a spine, which is part of their internal skeleton that includes a relatively short backbone with only ten vertebrae. This internal framework is one of the core attributes that classifies an organism as a vertebrate.

In addition, frogs belong to the class Amphibia, which are known to be ectothermic vertebrates that typically spend their life both in water and on land. They have four limbs (making them tetrapods), a three-chambered heart, and they breathe through lungs as adults. Frogs undergo metamorphosis, transforming from tadpoles with gills to air-breathing adults with lungs. The presence of limbs, an endoskeleton, and a complex nervous system also supports their classification as vertebrates.

Amphibians, in general, present a suite of evolutionary adaptations that facilitated the transition from aquatic to terrestrial life. The summary provides additional evidence that amphibian characteristics align with those of vertebrates, distinguishing them significantly from invertebrates, which lack a backbone and complex skeletal structure.

It is crucial that the process of mitosis is error free. This is because otherwise healthy cells can

Answers

Because the cells, if damaged or not made right, could become cancerous cells so therefore the answer is C

The right answer is Become cancer cells.

To multiply constantly, cancer cells bypass many regulations of cell proliferation, which leads them to proliferate uncontrollably. These cells have several solutions to prevent senescence.

In a healthy situation, a cell needs growth factors to proliferate. In a cancerous situation, the cancer cell can mutate an oncogene so that it permanently generates proliferation signals, regardless of the presence of growth factors.

For a cell to proliferate, the critical point it must pass through the cell cycle is the restriction point maintained by the Rb protein. Proliferation signals must be sustained to inactivate this control point as the rest of the cell cycle progresses without external stimulation. To proliferate excessively, the cancer cells thus overactivate the cell proliferation signals to pass the restriction point as quickly as possible. They use several strategies to over-activate these signals.

All organisms require nitrogen to make amino acids, which in turn are used to build carbohydrates

Answers

All plants take in carbon dioxide(CO) and use the carbon to build carbohydrates during photosynthesis, and all organisms require nitrogen to make amino acids(proteins), which in turn are used to build proteins. Nitrogen gas (N2) makes up 78 percent of Earth's atmosphere.

Final answer:

Organisms require nitrogen to synthesize amino acids, the building blocks of proteins, not carbohydrates. Nitrogen fixation by microorganisms converts atmospheric nitrogen into forms usable by plants, which animals then consume, making it a critical component of the nitrogen cycle.

Explanation:

The original statement that all organisms require nitrogen to make amino acids, which in turn are used to build carbohydrates, contains an error. In fact, organisms use nitrogen to synthesize amino acids, which are the building blocks of proteins, rather than carbohydrates. Atmospheric nitrogen (N2), which makes up about 79% of Earth's atmosphere, cannot be utilized directly by most organisms. Through a process called nitrogen fixation, certain microorganisms convert atmospheric nitrogen into forms that plants can absorb, such as nitrate ions (NO3−) and ammonium ions (NH4+). Once assimilated by plants, these nitrogen compounds can be incorporated into amino acids and eventually proteins. Animals obtain their nitrogen by consuming plants or other animals. The cycling of nitrogen between the atmosphere, soil, plants, and animals is an integral part of the nitrogen cycle, which is crucial for life on Earth.

Which femoral structure is located at the distal end of the medial supracondylar ridge?

Answers

The femoral structure that is located at the distal end of the medial supracondylar ridge (also known as medial supracondylar line) is what we call adductor tuburcle. The adductor tubercle also functions as the point of attachment for the adductor magnus muscle.

Final answer:

The adductor tubercle is the femoral structure found at the distal end of the medial supracondylar ridge, serving as an attachment point for the adductor magnus muscle.

Explanation:

Femoral Structure at the Distal End of Medial Supracondylar Ridge

The femoral structure located at the distal end of the medial supracondylar ridge of the femur is known as the adductor tubercle. This small protrusion is found on the medial condyle and serves as the point of attachment for the adductor magnus muscle. The medial epicondyle of the femur is a roughened area on the distal femur located on the medial side of the medial condyle, just above the adductor tubercle. The medial supracondylar ridge is a bony ridge that extends from the adductor tubercle down the shaft of the femur. The structures of the distal end of the femur, including the medial and lateral condyles, the epicondyles, and the patellar surface, articulate with the tibia to form the knee joint and provide attachment points for muscles and supporting ligaments.

How many amino acids are affected by a change in one nitrogen base?answer?

Answers

If one nitrogen base is changed, then one amino acid could change. Three nitrogen bases code for one amino acid. Sometimes, the change of one base can be hidden because for example, UCU and UCC both code for Serine (Ser).

It changes one amino acid in the genetic code if a change in one nitrogen base occurs because one triplet codon is responsible to make one amino acid.

What is genetic code?

DNA is the genetic material that stores information about the organism, this information is first converted into RNA by the process of transcription. After the transcription, this information is converted into the amino acid sequence.

Genetic code is the triplet sequence of a nitrogen base, which codes for the protein if any base is changed with another base, it will change the amino acid. Amino acid is made by triplet code, three bases are responsible for one amino acid.

Therefore, one amino acid is affected by a change in one nitrogen base, due to a triplet genetic codon.

Which of these happens during the postabsorptive state?

Answers

I found the whole exercise on the internet. These are the options:
"a. Blood glucose levels are maintained within an adequate range.
b. Fat reserves are built.
c. Glycogen is formed.
d. Glucose is broken down in the liver."

Correct answer: "a. Blood glucose levels are maintained within an adequate range."
Blood glucose levels are maintained by the breaking down firstly of glycogen in the liver, and then when this is gone, glycogen from the skeletal muscles is used and broken down into glucose. Never in this period, glycogen is being formed but it is rather the opposite. After all the glucose storage is consumed, fat is then also used to keep the levels of glucose stable and is never built.

C) About 10 percent of the desert tortoise's energy transfers to the coyote.

D) About 90 percent of the coyote's energy transfers to the desert tortoise.

Answers

well from what you've said, they'll end up with the same amount of energy from one another at the end as the coyote takes 90% from the desert tortoise and then the desert tortoise is taking 10% of the coyotes energy. At this point we would assume that the coyote ends up with 80% as he takes 90 but the tortoise takes back 10, however we are then told that the tortoise takes 90% of the coyote and the coyote takes 10% so it's exactly the same. Therefore, I can infer from this that the energy transfer would stay the same between the coyote and the desert tortoise. Hope this helps x

Answer:

C) About 10 percent of the desert tortoise's energy transfers to the coyote.

Explanation:

In the given food web, the coyote is the top consumer that feeds on desert tortoise and kangaroo rat. Only 10% of the energy of one trophic level is passed to the next trophic level and 90 % of the energy is lost in respiration.

Hence, only 10% energy of desert tortoise would be delivered to coyote and rest would be lost during respiration.
