The false statement about dinoflagellates is their fossil remains form limestone deposits.

Thus, the correct answer is E.

Dinoflаgellаtes аre motile unicellulаr аlgаe chаrаcterized by а pаir of flаgellаe. Mаny dinoflаgellаtes аre photosynthetic, whereаs others аre mixotrophic. Whereаs most аre strictly mаrine, some dinoflаgellаtes occupy brаckish аnd freshwаter environments.

Dinoflаgellаtes аlso exhibit remаrkаble trаits: In аddition to chlorophyll, some possess cаrotenoid pigments (dinoxаnthin аnd peridinin), giving them а flаmboyаnt red colorаtion, whereаs others аre bioluminescent. Some species form blooms in the oceаns, а phenomenon cаlled “red tide” due to colorаtion of the wаter resulting from the intense concentrаtion of аlgаl cells.

The signaling molecules used in endocrine signaling are called hormones. Hormones are chemical messengers that are produced by glands in the endocrine system and released into the bloodstream, where they can circulate throughout the body and regulate the function of various organs and tissues. Some examples of hormones include insulin, thyroid hormone, and estrogen.

Explanation:

The restriction enzymes when combined with the DNA containing restriction sites lead to cuts at those sites yielding restriction fragments. The second statement is correct.

The restriction enzymes are the enzymes that recognize specific sites known as restriction sites. These are enzymes that are found in bacteria and this feature is used as a modern biotechnology tool for genetic editing.

There are two ways the ends are formed after the action of a restriction enzyme. It can form blunt ends or sticky ends. The sticky ends have a region at the end that is single-stranded. This region can then join according to the complementary base pairing with another strand having complementary sticky ends.  

If it is assumed that the RE (restriction) enzyme is not interrupted during the generation of restriction fragments, the resulting restriction fragments would not yield more restriction fragments when re-incubated with the RE enzyme.

A restriction enzyme cuts only at restriction sites forming restriction fragments that do not yield more restriction fragments on subsequent action of the restriction enzyme.

In conclusion, the action of restriction enzymes on DNA gives smaller fragments of DNA. The second option is correct.

A sharp increase in capillary hydrostatic pressure would directly cause an increase in fluid movement to the interstitial spaces.

Capillary hypertension causes the production of a protein-poor ultrafiltrate, which when it enters the interstitial space increases the amount of the interstitial fluid.

A rise in small artery, arteriolar, or venous pressure raises capillary hydrostatic pressure, which favors filtration. Fluid filtration will be reduced if the hydrostatic pressure gradient (PC - Pi) reduces due to an increase in interstitial pressure. Large rises in tissue interstitial pressure, on the other hand, can cause tissue damage and cellular death.

Edema occurs when plasma oncotic pressure falls, hydrostatic pressure rises, capillary permeability rises, or a combination of these variables occurs. When lymphatic flow is impeded, edema can develop.

Darwin did not know that genetics existed, but he did collect evidence from birds with a common ancestor and theorized that they split because of evolution.

Have a good day!

The one strength of Darwin's theory is the large amount of data which is supported by his work. Thus, the correct option is C.

Darwin proposed a theory which describes that a species can change over time, that a new species come from the pre-existing species, and that all the species share a common ancestor. In this model of Darwin, each species has its own unique set of heritable or genetic differences from the common ancestor, which have been accumulated gradually over a period of very long period of time.

Darwin used multiple lines of evidence to support his theory of evolution of population through natural selection such as fossil evidence, biogeographical evidence, and anatomical evidence. The one strength of Darwin's theory is the large amount of data which is supported by his work.

Genotype alludes to the alleles you have for a specific quality or set of qualities. phenotype is the actual quality itself, which might be affected by genotype and natural variables.

The term "phenotype" alludes to the detectable actual properties of a life form; these incorporate the organic entity's appearance, improvement, and conduct. An organic entity's not entirely set in stone by its genotype, which is the arrangement of qualities the living being conveys, as well as by natural impacts upon these qualities.

A singular's genotype is the blend of alleles that they have for a particular quality. A singular's aggregate is the mix of perceptible attributes or qualities. While a living being's genotype is straightforwardly acquired from its folks, the phenotype is just impacted by the genotype.

In the process of transcription, DNA is used as a template for making another type of nucleic acid called RNA. The process begins when the enzyme RNA polymerase binds to a region called the promotor.

Transcription is a genomic process in which RNA is generated from DNA. This will generate an mRNA that will contain the genetic information of the protein that the gene encodes.

Transcription will be generated in the nucleus of the cell, there the RNA polymerase will bind to the DNA in the promoter to begin to generate the RNA copy, generating a transcription bubble to generate the RNA.

The transcription is preceded by the traduction that will take place in the cytoplasm of the cell to generate proteins from the mRNA.

Therefore, we can confirm that in the process of transcription, DNA is used as a template for making another type of nucleic acid called RNA. The process begins when the enzyme RNA polymerase binds to a region called the promotor.

The cortical areas indicated by E are involved in the functions of the production and interpretation of language.

The true choice is A.

The most important part of the brain in language activities is the cerebrum. The part of the cerebrum that is directly involved in language processing is the cerebral cortex. The cerebral cortex is the part that looks like white lumps and is the largest part of the human brain system. This section regulates or manages cognitive processes in humans, and one of them, of course, is language.

The cerebral cortex consists of two parts, namely the left hemisphere and the right hemisphere. The right hemisphere controls the processing of spatial and visual information (seeing, coloring, or perceiving spaces or objects in three dimensions). While the left hemisphere controls language activities besides, of course, other cognitive processes. Coordination between the two is possible because of the structure that identifies these two parties, namely the corpus callosum.
