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.

What are the products of krebs cycle?
Answer:
What are the Krebs Cycle products? Electron Carriers (NADH and FADH2), ATP, and Carbon Dioxide.
Explanation:
For one cycle, two molecules of carbon, three molecules of NADH, one molecule of FADH2 and one molecule of ATP or GTP are produced. Each glucose molecule produces two molecules of acetyl CoA, enough for two cycles. These products can be multiplied by two to produce the per-glucose yield. Though only one ATP (or GTP) is produced directly per cycle, the products NADH and FADH2, can produce ATP (or GTP) in a further process of cellular respiration called oxidative phosphorylation. The main function of the Krebs cycle is to produce energy, stored and transported as ATP or GTP. The cycle is also central to other biosynthetic reactions where the intermediates produced are required to make other molecules, such as amino acids, nucleotide bases and cholesterol. The Krebs cycle is found in all cells that use oxygen. Combined with the process of oxidative phosphorylation, the Krebs cycle produces the majority of energy used by aerobic cells with the percentage energy provided for humans being greater than 95%.
A scientist at the polar ice cap was studying an ice sample from hundred of meters below the surface. While examining the ice, the scientist found some cells from many years ago. Using an electron microscope, the scientist identified these cell structures: a cytoskeleton, mitochondrion, nucleus, cell wall, and ribosomes. What kind of organism did the scientist find? (LS1.2)a. plantc. virusb. bacteriad. animal
Answer:
the organism is a plant.
Explanation:
As the scientist, a cytoskeleton, mitochondrion, nucleus, cell wall, and ribosomes, we can say that it is a eukaryotic cell since it has a differentiated nucleus. Also within eukaryotic cells, plant cells are those that have cell walls.
All structures are typically found in a plant cell.

How can humans influence traits in dogs or other organisms?
Answer:
In artificial selection, humans have the capacity to influence certain characteristics of organisms by selective breeding. One can choose desired parental traits determined by genes, which are then passed on to offspring.
Dog breeding is another prime example of artificial selection. Although all dogs are descendants of the wolf, the use of artificial selection has allowed humans to drastically alter the appearance of dogs.
Explanation:
Humans can influence traits in dogs or other organisms by the process of artificial selection through which desired characters can be added to the offspring.
How can humans influence traits in other organisms?Humans can influence the process of natural selection by the process of artificial selection, or selective breeding. In artificial selection, humans can select a specific set of desirable traits in the agricultural plants or animals, and thus produce desirable offspring (products) for benefit.

The function of the cork cambium is to produce
Answer:
The cork cambium produces cork and phelloderm.
Explanation:
Cells' structural components decide their function. Cells arrange themselves into tissues, where specialized cell types carry out their functions in tandem. As cells mature, their function may even change over time, as they undergo certain subcellular changes in protein expression and signaling.
In larger plants, rigid tissues are needed to help support their modified stems, and transport water, minerals, other nutrients and food to different regions. Cork cambium is an unspecialized tissue found in the outermost plant layers. These act as meristematic regions; here, new tissues arise, growing outwards- these include:
phelloderm- they mature into inner secondary cortex cork- dead air-filled cells called cork that form a strong protective layer on the stems of woody vascular plants.Animals in the taiga and alpine biomes hibernate during winter.

The crossing of a hybrid and a dominant purebred will always result in offspring which are what?
Answer:
Dominant
Explanation:
A hybrid trait is also known as heterozygous, which is the combination of the dominant and recessive alleles of a gene. On the other hand, a purebred is combination of the same two dominant alleles or the same two recessive alleles. For example, in the gene coding for height, allele for tallness (T) is dominant over the allele for shortness (t).
A purebred for this trait will either be "TT" or "tt" while a heterozygous or hybrid will be Tt. Hence, according to this question, crossing of a hybrid (Tt) and a dominant purebred (TT) will always result in offspring which are DOMINANT (see attached image).

Within the mitochondrial matrix of mitochondria, the Krebs cycle occurs. In the cytoplasm of the cell, glycolysis happens, hence option C is correct.
What is Krebs's cycle?The Krebs cycle processes occur in the mitochondrial matrix, a dense solution that surrounds the mitochondrial crests in eukaryotes. In addition to water, the matrix also includes all the enzymes, coenzymes, and phosphates required for the cycle's biochemical reactions.
While the majority of anaerobic (without oxygen) and aerobic (with oxygen) respiration respectively occurs in the cytoplasm and mitochondria of the cell.
The cycle occurs in the mitochondrial matrix and results in the production of chemical energy in the forms of ATP, FADH2, and NADH.
Therefore, in the mitochondrial matrix of mitochondria, the Krebs cycle occurs, hence option C is correct.

Landslide is the massive movement of material from high altitude to low altitude, producing slope breaks. The correct option is B. The type of mass movement described in the example is landslide.
What is a landslide?A landslide can be defined as a massive movement of materials that include rocks, soil, plants, debris, and other elements composing the ground.
Mass of material moves from high altitude to low altitude due to the action of gravity and the influence of other factors as humidity excess.
These movements occur because the material is exposed to external forces (gravity) that supersede the strength of these materials producing slope breaks.
Other factors such as rains, increase in water level, snowmelt, erosion, earthquakes, human activities, and others influence the landslide occurrence.

Why do you think the Staghorn coral's skeleton is so lightweight?
Answer:
The success of staghorns is partly due to their lightweight skeletons, which often grow quickly enough to outcompete other corals for sunlight, a resource demanded by their photosynthesizing algae.
