Explanation:
Mine has multiple answers but if yours doesn't I hope this helps!
The tentacles of an octopus and the limbs of a lizard are analogous organs. So the correct option is B.
What are analogous organs?The organs possessed by different species which have different anatomical structures but perform the same function as one another are called analogous organs. The development of analogous organs is a form of convergent evolution.
In convergent evolution, different types of species evolve separately and independent of each other but at some point, their functions or the functions of their organs converge with one another.
These analogous organs are developed in totally unrelated species but due to their environment, their evolution works in such a way that they develop in a similar way even after sharing no similarities with each other.
The convergent evolution giving rise to analogous organs is called homoplasy in terms of cladistics.
Thus, the tentacles of an octopus and the limbs of a lizard are analogous to each other. Therefore the correct option is B.

Which describes the two cells formed through mitosis?
They are identical to each other but unlike the parent cell.
They are different from each other and the parent cell.
They are identical to each other and to the parent cell.
Answers
Answer:
The third one.
Explanation:
Mitosis doubles the DNA and then splits the cell in two so it will have identical daughter cells.
Answer:
They are identical to each other and to the parent cell.
Explanation:
Mitosis is used to produce daughter cells that are genetically identical to the parent cells. The cell copies - or 'replicates' - its chromosomes, and then splits the copied chromosomes equally to make sure that each daughter cell has a full set.

How does a lion get its source of nitrogen to form its DNA or proteins?
Answers
Answer: The protein in their diets
Explanation:
The lion gets its source of nitrogen to form protein in its diet.
What is protein?Proteins are macronutrients that are present in foods. There are two types of proteins. Essential and nonessential. Non-essential proteins are synthesized in the body and essential proteins are needed to eat by taking food.
A lion is an animal, and animals synthesize some proteins in their body, and some proteins are to be taken from the food. Protein is necessary for the growth of the body. It gives strength to the body.
The protein synthesis is done in the cell of the animals. But the nitrogen, that the animals get is from the diet they eat which is meat and plants. It depended upon its diet. Some animals are carnivorous and some are herbivorous.
Therefore, the lions get their protein from their diet.

Why is it logical for the level of FSH to fall greatly following ovulation?

During each menstrual cycle, there is a rise in follicle stimulating hormone (fsh) in the first half of the cycle that stimulates follicular growth in the ovary. After ovulation the ruptured follicle forms a corpus luteum that produces high levels of progesterone. This inhibits the release of fsh!
In 1815 a volcano erupted spewing billions of tons of ash into the sky. This ash "cloud" caused global annual temperatures to drop below normal, causing "a year without a summer" in 1816.Which sphere did this ash "cloud" affect to cause these changes? *
Answers
Answer:
The Atmosphere
Explanation:
1816 was a year without summer because the billions of tons of ash that was spewed blocked radiation preventing it from reaching the surface of the earth.
A volcano is a break in the crust of planetary bodies like Earth that allows gasses, volcanic ash, and hot lava to escape. Volcanos are one of the major factors that cause climate changes on Earth mostly because of their cooling effect.
The ash, gasses and lava usually escape to the atmospheric layer of the earth with their cooling effect. And they cool the earth by blocking incoming solar radiation. This can go on for months or years depending on the components and severity of the eruption and can lead to "a year without summer" as witnessed in 1816.

D) All of the above
Whether a molecule can cross the plasma membrane depends upon D. All of the above
Which molecule can pass the plasma membrane?
Small nonpolar molecules, consisting of O2 and CO2, are soluble in the lipid bilayer and consequently can effectively cross cell membranes. Small uncharged polar molecules, which include H2O, can also diffuse thru membranes, however large uncharged polar molecules, inclusive of glucose, cannot.
How do molecules pass across the plasma membrane?Explanation: Molecules pass throughout the plasma/mobile membrane through diffusion. If they're not small sufficient, they need to break down by means of other substances, which include enzymes, which can be biological catalysts. If they are small enough, usually, the easiest way for them to move is through diffusion.

Metal are malleable and ductile. Explain on the basis of the electron sea level?
Answers
Metallic Bonding is restricted to metals only. In the metallic bonding, There is a electrostatic force of atrraction between the metal ions (which are positive)
and the electrons(which are negative).
The metal ions are arranged in a lattice pattern which is the regular repetitive structure.
_____________________________________Electron Sea Level:Every metal atom donate one or two valence electrons, so due to the BULK presence of the electrons, It results in a formation of sea of electrons. So the valence electrons don't just stay on their own atom, they roam around the whole metal. They are just like a sea of electrons. This is why it is called the electron sea model. basically metal ions are present as a iceberg or island in the freely floating sea of electrons.
_____________________________________How is Sea of electron related to the malleable and ductile property?The sea of electron works as a electron GLUE, That means the metal ions are strongly ATTRACTED to the electron, so When apply pressure on the metals they DONT BREAK that means they are not brittle but malleable and ductile. This is because of the moving electrons and because the cations slide easily past each other, The ability of the atoms to roll over each other into new positions without breaking the metallic bond is because of the electron glue.
_____________________________________IMPORTANT STATEMENTSBrittle; Hard but breakable due to absence of sea of electron.
Malleable and Ductile; Transformed into sheets and thin wires so they are somewhat ELASTIC.
A student claims that the monarch population increases and decreases in a cycle, similar to the pattern of predator-prey populations like wolves and moose. Use the data to evaluate this claim
Answers
Answer:
yes that is true because by looking at the graph you can tell that it starts to increase then slowly decrease.
Explanation:
The monarch population represented by the graph depicts a fluctuating pattern which epitomizes a rise and fall pattern in the area occupied by monarchs over the winter season between 1995 and 2005.
The predator-prey population depicts the sharp decline in the prey population as they are being fed on in large numbers as the number of predator multiplies. This is followed by a decrease in the number of predators due to starvation as the available prey are insufficient to cater for their number. The cyclic nature of the graph shows similar pattern as areas occupied by monarchs declines as the winter season progresses over time.Learn more :https://brainly.com/question/18576344?referrer=searchResults
