Which statement is true regarding the taxonomic system?
Charles Darwin was the primary creator of the current taxonomic system.
All of the past, extinct species have been cataloged.
The current taxonomic system is based on the Linnaean classification system.
All of the current, living species in the world have been cataloged.
Answer:
1) taxonomy
2) species
3) the animal has sharp, pointed teeth
4) the current taxonomic system is based on the Linnaean system
5) he only had two kingdoms, animals and plants
Explanation:
did the quich check
The statement 'the current taxonomic system is based on the Linnaean classification system' is TRUE.
Taxonomy is a field of study focused on naming and classifying groups of organisms according to their morphological and genetic features. The taxonomic system organizes species from larger to more specific taxonomic categories in a hierarchical system.The botanical taxonomist Carolus Linnaeus is considered the father of taxonomy because he was the first person to formulate a system for classifying different species of plants and animals.Nowadays, the taxonomic system includes eight (8) categories from larger to more specific: domain, kingdom, phylum, class, order, family, genus, and species.In conclusion, the statement 'the current taxonomic system is based on the Linnaean classification system' is TRUE.

how do organisms with many cell types develop from a single cell
Cell division, torso axis formation, tissue and organ development are all part of development, and cell differentiation refers to acquiring a final cell type identity.
What is cell division?The process by which a parent cell divides into two daughter cells is known as cell division.
Cell division is usually part of a larger cell cycle during which the cell grows and replicates its chromosomes before dividing.
Cell division occurs in two stages: mitosis and meiosis. When most people say "cell division," they're referring to mitosis, the process of creating new body cells.
Meiosis is the process by which egg and sperm cells are formed. Mitosis is a necessary process for life.
Multicellular organisms form in a variety of ways, including cell division and the aggregation of many single cells. Colonial organisms form when many identical individuals band together to form a colony.
Thus, this way, organisms with many cell types develop from a single cell.

Answer:
Both are multicellular (plants have different cells for the leaves and the stem, animals have skin cells, brain cells etc so they are called multicellular).
Plants are autotrophic - they make their own food (glucose) by photosynthesis
Animals are heterotrophic - they eat other organisms, cannot make their own food.

Explain how sexual and asexual reproduction both lead to better evolutionary fitness.
Answer:
Hope you get done. friend me back. and can I have brainliest
Explanation:
To get diversity in individuals, genetic differences are required, and different phenotypes must be expressed. Since sexual reproduction is more conducive to driving evolution than asexual reproduction, much more genetic diversity is available for natural selection to work on. Evolution can happen over time.
The routes nerve impulses from our senses.
A. thalamus
B. hippocampus
C. brain stem
D. corpus callosum
Answer:
a
Explanation:
The correct answer is C. Brain Stem.
How does the brain stem function?The thalamus and other areas of the brain receive nerve signals from our senses through the brain stem. It is made up of the medulla, pons, and midbrain and is situated at the base of the brain.
The brain stem is in charge of regulating life-sustaining processes including breathing, heart rate, and blood pressure. It is also in charge of transmitting sensory data from the body to the thalamus, which subsequently transmits the data to the relevant parts of the brain.
Although the brain stem is the main pathway for nerve impulses from our senses, the hippocampus, corpus callosum, and thalamus are all important in the processing of sensory information.

Ronald observes a sparrow's nest in a shrub outside his home. The table below describes his findings.
Week
Observations
1
Six eggs were laid in the nest.
3
Five eggs hatched, and one egg did not hatch.
One of the chicks disappeared.
7
Three of the chicks learned to fly, and another one disappeared.
What part of natural selection did Ronald observe?
adaptation
overproduction
selection
variation
Answer:
B. Overproduction
Explanation:
Overproduction is one of the main part of natural selection whereby an organism reproduces more offspring, of which only a few would be able to survive given the environmental condition amd factors that would be against the survival of the offspring to maturity.
From Ronald observation, we can see that the bird produces more eggs than would survive. Only 3 of the chicks survived.

Students in a Biology class were formulating an argument about a cell they viewed under the microscope. Half
of the class argued it was a plant cell and the other half argued in favor of an animal cell. Below is the image the
students saw under the microscope. Which argument is supported by the image?
A. The students who said the plant cell are correct because there are chloroplasts
B. The students who said a plant cell are correct because there are mitochondria present.
C. The students who said animal cell are correct because there are chloroplasts present.
D. The students who said an animal cell are correct because there are mitochondria present.
Answer:
the answer would be A
Explanation:
Animal cells are oval and egg shaped so we can cancel out c and d
A is the correct answer because we can see green dots within the structure. Chloroplasts contain a green pigment called chlorophyll. This green pigment makes the chloroplast and the structure green (as we can see in the picture). Photosynthesis occurs in the chloroplasts, and it is where the plant gets its glucose from
