Mark me brainliest please I really need itExplanation:
In biology, evolution is the change in the characteristics of a species over several generations and relies on the process of natural selection. The theory of evolution is based on the idea that all species are related and gradually chamge over time.Darwin's theory consisted of two main points; 1) diverse groups of animals evolve from one or a few common ancestors; 2) the mechanism by which this evolution takes place is natural selection.Evidence that supports the theory of evolution are fossils, embryological studies, anatomical and morphological characteristics (homologous organs, analogous organs, vestigial organs), molecular biology (comparing DNA sequences).What is the only form of nitrogen that plants can absorb?.
The only nitrogen plants can absorb is nitrate. Nitrogen assimilation in plants. Plants absorb nitrogen from the soil in the form of nitrate (NO3−) and ammonium (NH4+). In aerobic soils where nitrification can occur, nitrate is usually the predominant form of available nitrogen that is absorbed.

B
The lizard and humans share a common ancestor because of the presence of a backbone and legs.
С
The trout and humans share a common ancestor because of the presence of a backbone.
D
Earthworms were the most recent to evolve because of the absence of the derived characteristics
The lizard and humans share a common ancestor because of the presence of a backbone and legs statement is true.
What is Evolution?Evolution refer to the change or variation in in the characteristics of organisms over several generations and this depends on the process of natural selection.
some Organisms evolved from the same ancestors and they share some similarities in characteristics like hair, legs.
Humans and lizards evolve from same ancestors of over 320 million years ago.

What are the different systems of classification of organisms
Answer:
kingdom, phylum, class, order, family, genus, and species.
Explanation:
kingdom, phylum, class, order, family, genus, and species.
Classification is a grouping of individuals according to their similarities and differences. It is used to group organisms according to ranks of similar characteristics and evolutionary basis.
What are the levels of classification?Classification system is divided into various levels in order to rank the organisms.
It has following levels:
Kingdom: It is the highest level of classification. There are a total of five kingdoms.Phylum: It is classified on the basis of phenetics and phylogenetics.Class: each phylum can contain multiple class.Family: it is group of genera having similar traits.Genus: it helps to determine species of the organisms.Species: it is the lowest rank in this category. It is group of organisms having similar characteristics.Thus, kingdom, phylum, class, family, genus, species are the classification system of organisms.

During cell polarization, what are the two resultant edges called?
Answer:
The leading and trailing edge
Explanation:
Cutting the front edge of each wave's half cycle using leading edge dimming. Trailing edge dimming, on the other hand, eliminates the second half of each wave's half cycle.
~
During cell polarization, the two resultant edges are called the leading edge and the trailing edge.
What do you mean by Cell polarization?Cell polarization may be defined as a phenomenon by which cytoskeletal arrangement, extra- and intracellular signals, and organelle and membrane reorganization occur due to maintaining the cell shape.
Leading-edge works on the front edge and separates the half-wave cycle, while the trailing edge works on the back edge and cuts the second half of the wave.
Therefore, during cell polarization, the two resultant edges are called the leading edge and the trailing edge.

Neurons in the visual cortex respond to which type of stimulus?
Answer:
luminance
Neurons in the visual cortex respond essentially to the variations in luminance occurring within their receptive fields, where each neuron fires maximally by acting as a filter for stimulus features such as orientation, motion, direction and velocity, with an appropriate combination of these properties
Explanation:
Neurons in the visual cortex respond to luminance stimulus. They respond selectively to various stimuli depending on the features.
What do you mean by Neurons?Neurons may be defined as the cells which are responsible for receiving sensory input from the external world and processed in the brain.
Neurons in the primary visual cortex respond to local edges or contours at a particular orientation, motion, direction, and stereoscopic depth.
Therefore, neurons in the visual cortex respond to luminance stimulus.
