Summarize why the monocot and dicot distinction is inconsistent with recent evolutionary information

Answers

Answer 1
Recent studies of  DNA on both monocots and dicots indicates that the monocot and dicot distinction does not completely reflect the evolutionary relationship of both plant groups. Recent data suggests that the hypothesis of monocots form from a clade but reveals the species known as dicots are polyphyletic. This means that monocot could arise form a group of organisms that believed to evolved from a common ancestor. However, dicots are considered to arise from a loosely unrelated organisms descended from one or more ancestors.

Final answer:

The nucleolus is the structure inside the nucleus responsible for producing ribosomes by assembling ribosomal RNA with proteins. Subunits of ribosomes are transported to the cytoplasm through nuclear pores for protein synthesis.

Explanation:

The structure found inside of the nucleus that helps produce ribosomes is called the nucleolus. The nucleolus aggregates ribosomal RNA (rRNA) with associated proteins to assemble ribosomal subunits. These subunits are essential for protein synthesis and are transported out of the nucleus through the nuclear pores to the cytoplasm.

Chromosomes within the nucleus contain sections of DNA that encode ribosomal RNA. The nucleolus, a darkly staining area in the nucleus, centralizes the production of rRNA necessary for constructing ribosomes. Finally, the ribosomes, which are responsible for making proteins, move to the cytoplasm where they decode genetic messages into amino acids and build proteins.

A(n) _______ is often responsible for our disliking of a particular food after gastric illness.

a. odor trauma

b. learned taste aversion

c. virus

d. odor dilemma

e. restricted aversion

Answers

b. learned taste aversion

Final answer:

A learned taste aversion is the psychological phenomenon responsible for disliking certain foods after feeling ill. It is considered an evolutionary adaptation to help avoid harmful foods, demonstrated through research that shows how organisms are conditioned to avoid tastes associated with sickness.

Explanation:

A learned taste aversion is often responsible for our disliking of a particular food after gastric illness. This phenomenon occurs when an association is formed between a food item consumed and a subsequent feeling of nausea or illness, despite the fact that the food itself might not be the actual cause of the illness. This type of conditioning is quite robust, and an interval of several hours may pass between the ingestion of the food (the conditioned stimulus) and the onset of nausea or illness (the unconditioned stimulus).

Research into taste aversion reveals that it may be an evolutionary adaptation that helps organisms quickly learn to avoid harmful food, thus contributing to species survival through natural selection. Experiments, such as those conducted by Garcia and Koelling, have demonstrated that certain types of conditioning have biological constraints, showing that rats could easily be conditioned to avoid flavors associated with illness, but not lights and sounds. This emphasizes that classical conditioning can be critical for helping organisms avoid dangers to their health.

Based on this genetic information, which phylogenetic tree is most parsimonious? select the most parsimonious tree. if there is a tie, select both trees. (for help approaching this problem, open hint 2.)

Answers

Final answer:

The most parsimonious phylogenetic tree is one that implies the fewest character changes, namely the fewest reversals, independent changes, and total changes. To build these trees, scientists collect and analyze both morphologic and molecular data, then use cladistics to organize the events. However, without the specific trees to study, we can't identify the most parsimonious one.

Explanation:

Based on the idea of maximum parsimony, the most simple and obvious phylogenetic tree with the fewest character changes is considered the best. With this approach, the fewest number of character reversals, independent character changes, and total character changes throughout the tree, is most ideal. To construct the tree, scientists use character information, and morphologic and molecular data to identify homologous characteristics and genes. Once homologies are identified, cladistics helps to organize these elements to provide an evolutionary timeline with the least number of major divergences. So without the specific trees to inspect, we cannot identify the most parsimonious one, but now you know how to evaluate it when provided.

Explain three differences between apomictic and automictic parthenogenesis.

Answers

apomictic refers to plants and it means the offspring is genetically identical to the parent. Automictic means that gametes fuse after meiosis - which means offspring are genetically not identical to parents.

A plant's progeny is said to be apomictic if it is genetically identical to its parent. Automictic reproduction occurs when gametes combine after meiosis, resulting in children that are genetically distinct from their parents.

What is apomictic and automictic parthenogenesis?

Apomictic parthenogenesis results in children who are exact clones of their mothers. Among them are aphids. Meiotic parthenogenesis is more challenging. Sometimes, the progeny are haploid (for example: male ants).

A haploid cell may duplicate its chromosomes via automixis (also known as automictic parthenogenesis), or it may combine with another haploid cell. In each instance, diploid zygotes mature into diploid adults.

In apomictic parthenogenesis, which is frequent in plants, the diploid germ line cells (gametocytes) undergo ordinary cell division, or mitosis, rather than meiosis to produce gametes; the children are clones of the mother. The children of automictic parthenogenesis, also known as automixis, are partially clones of the mother.

Therefore three differences between apomictic and automictic parthenogenesis are explained.

There are choices for this question namely:

A) B cells produce IgE antibodies
B) B cells release cytokines
C) cytotoxic T cells present the class II MHC molecule-antigen complex on their surface
D) helper T cells release cytokines

The correct answer is "helper T cells release cytokines". Cytokines are released by helper T cells when B cells attach to them via receptors. These T cells "help" these B cells to differentiate by secreting certain cytokines. When B cells differentiate, they are converted to plasma cells and able to secrete antibodies to the antigen presented to the T cells.

B.They both result in a subspecies evolving into a subpopulation.

D.They both involve speciation due to physical barriers.

I Think The Answer is A. but i'm not sure tell me if i am correct or not! They both are mechanisms by which new species arise.





Answers

They both are mechanisms by which new species arise.

Sympatric speciation and allopatric speciation are both mechanisms of species creation. Allopatric speciation occurs when a population is physically divided and evolves distinctly, while sympatric speciation happens within the same location, often due to niche differentiation or genetic changes causing reproductive isolation.

Indeed, you are correct. Both sympatric speciation and allopatric speciation are mechanisms by which new species arise. Allopatric speciation occurs when a population is separated by a physical barrier (like a mountain or a river), which prevents gene flow between different groups in the population. Over time, these isolated groups may diverge and form new species.

On the other hand, sympatric speciation, which is less common, happens without a physical barrier. Instead, it can occur when a subpopulation evolves to exploit a different niche or when genetic changes result in reproductive isolation within the same location.

Thus, in essence, both processes result in the formation of new species, which is why your answer is correct in stating that they are mechanisms by which new species arise.
