Which is true about frogs and loads?
Answer:
theres no question
Explanation:
Answer:
Frogs and toads are both members of the same class — Amphibia — which means that they're both amphibians. Amphibians are cold-blooded vertebrates that spend the early part of their lives in water (breathing with gills) and the rest of their lives on land (breathing with lungs).

Although some bacteria have membranes around their DNA, we do not call these structures nuclei because they lack ____. a. pores b. ribosomes c. phospholipids d. proteins e. a bilayer construction
Answer:
A. Pores
Explanation:
To be considered nuclei, the DNA membrane structures have to have pores.
Nuclear pores are necessary to connect the nucleus with the cytoplasm, and to regulate the transportation of materials between the two areas.
So, the correct answer is A.
Geothermal energy is derived from the sun.
Please select the best answer from the choices provided
T
F
i think that the answer would be False
Geothermal energy does not come from the sun, though. The heat that exists within the Earth is converted into geothermal energy. This heat is a result of the creation of the Earth, radioactive element decay, and solar energy absorption by the Earth's surface.
What is the source of majority of the heat ?The majority of the heat that drives geothermal energy comes from the Earth's creation. The heat that was generated during the Earth's formation resulted in a layer of molten rock surrounding the planet's core.
The heat for geothermal energy comes from this molten rock, which is still there today. The heat of the Earth is also influenced by the radioactive elements' decay.
Throughout their long-term decay, radioactive elements like uranium and thorium release energy into the a heat source. Geothermal energy is also fueled by this heat. The heat of the Earth is also influenced by the solar energy that the Earth's surface absorbs. The Earth's surface absorbs the sun's rays, and the heat is then retained in the planet's core. Geothermal energy is then produced using this heat.
Therefore, geothermal energy is not produced by the sun. Geothermal energy is produced by the Earth's internal heat, which is produced by the creation of the planet, radioactive element decay, and solar energy that the Earth's surface absorbs.

ATP synthase depends on the facilitated diffusion of which of the following to make ATP? *
1 point
A. Hydrogen ions
B. Oxygen
C. Water molecules
D. Carbon dioxide
Hydrogen ions pass through ATP synthase to transform ADP into ATP(ADP+H₃PO₄-->H₂O+ATP)
ATP synthase extract energy from the hydrogen ion gradient by allowing the facilitated diffusion of hydrogen ions to make ATP. So, the correct answer is (A).
What is ATP Synthase ?ATP synthase is a mitochondrial enzyme which is located in the inner membrane. It catalyzes synthesis of ATP from ADP and phosphate.
ATP synthase consists of two protein entities, those are [tex]F_{1} and F_{0}[/tex] which are soluble protein situated in mitochondrial matrix and is bound to inner mitochondrial matrix respectively.
F1 is composed of three copies of each of subunits α and β, and one each of subunits γ, δ and ε. F1 subunits γ, b and ε constitute the central stalk of complex.
It is driven by the flux of protons which across a gradient generated by electron transfer from the proton chemically positive to the negative side.
It also referred to as Complex V or [tex]F_{1}- F{0}[/tex] synthase.
Thus, ATP synthase extract energy from the hydrogen ion gradient by allowing the facilitated diffusion of hydrogen ions to make ATP. So, the correct answer is (A).

Answer: nebula
Explanation:
Because it's right.
Nebula contains the ingredients for a star to be born. Thus, option A is correct.
What is nebula?
A nebula is a large cloud which is composed of gas and dust in space contain hydrogen, helium, and/or plasma; They are also called as nurseries, because these are the address where stars are created and born.
There are different kinds of nebula formations with no clear beginning or end, and no clear boundaries called as diffuse nebulae.
The formation of Other kinds of nebulae are the explosions of dying stars, called as supernova remnant nebulae, some are planetary nebula which is created with the loss of material from a red giant phase of a dying star.
To take the picture of nebula astronomers use very powerful telescopes are used like Space telescopes such as NASA's Spitzer Space Telescope and Hubble Space Telescope are used.

While writing a paper on cancer, Maria discovers a lot of information about what happens in a cell to cause the uncontrolled growth that is characteristic of cancer. Which statement most correctly explains the uncontrolled growth?
Answer:
Explanation:
Cancer is unchecked cell growth. Mutations in genes can cause cancer by accelerating cell division rates or inhibiting normal controls on the system, such as cell cycle arrest or programmed cell death. As a mass of cancerous cells grows, it can develop into a tumor.
The statement that most correctly explains the uncontrolled growth is During the G1 phase of the cell cycle, the DNA continued to replicate repeatedly, causing it to grow into a cancerous tumor. The correct option is A.
What is cancer?Cancer is a genetic disease that causes tumors in the body. Cancer happens due to genetic changes. The normal cells convert into cancer cells.
The cancer cells grow and divide rapidly. Their uncontrolled growth and division cause the situation of tumors in the body. Cancer cells are treated to stop the division, but it is a hard process.

reaction?
A) synthesis of coenzymes by enzymes
B) initial formation of an enzyme-substrate
complex
C) separation of the enzyme and the products of
the reaction
D) destruction of the enzyme
Answer:
C)
Explanation:
separation of the enzyme and the products of the reaction.
The activity that complete the enzyme-controlled reaction is separation of the enzyme and the products of products. The correct option is C.
What is enzyme controlled reaction?Using enzymes to manage biochemical reactions is an important part of cellular maintenance.
Enzymatic activity enables a cell to respond to changing environmental demands and regulate metabolic pathways, both of which are critical for cell survival.
Enzyme-controlled reactions are broadly classified as those that create a new, larger molecule from two or more substrates (anabolic reactions) and those that break a molecule into smaller parts (catabolic reactions).
Enzymes basically aid in the acceleration of certain chemical reactions in the human body. They are required for respiration, digestion, muscle and nerve function, and thousands of other functions.
Detachment of the enzyme and the products of components is the activity that completes the enzyme-controlled reaction.
Thus, the correct option is C.

write some differences between unisexual and bisexual organisms
Answer:
Unisexual and bisexual organisms are differentiated based on the reproductive systems they posses. Unisexual organisms have separate sexes male or female. Male and female reproductive systems are present in different individuals hence unisexual organisms produce male or female gametes but never both. Bisexual organisms have both male and female reproductive systems within the same individual. Hence, they are capable of producing both types of gametes. Some flowers are unisexual, and they possess only pistils or stamens. Some flowers are bisexual, and they possess both stamens and pistils together. This is the difference between unisexual and bisexual organisms.
