Hello there!!

I love protozoa so this should be fun.

1. Protozoans are unicellular beings that live in wet environments.

2. Protozoans have 2 prevalent ways of feeding:

a) the most common is utilized by heterotrophs like amoeba. An amoeba extends its elastic body until it completely surrounds the victim. Then the amoeba simply has to digest its food.

b) The second most common is through cilia. Paramecia use this method. The hair-like cilia in its mouth catch hold of food and push the meal into the paramecium's digestive tract.

3) The only protozoan to have its own family is Euglena.

4) Euglena has its own family because it has chloroplasts (meaning it can undergo photosynthesis) but it can also feed like a heterotroph. Because Euglena exhibits both plant and protozoan qualities, it has its own category.

5) Rotifers move by two spinning wheels of cilia. This type of propulsion makes the rotifer a speedy little protozoan.

I hope this answers your question. :)

(please pick as Brainliest)

There are several microorganisms all around us, they all come in different shapes and sizes. It might be quite difficult to identify one organism from the other. To solve this problem scientists came up with a method of naming and grouping microorganisms into different categories, this method is known as TAXONOMY.

Taxonomy is the method of classifying different organisms into various groups. The scientist that first came up with this method is known as Carl Linnaeus. The different categories include; kingdom, phylum, class, order, family, genus, species.

Hence scientists group similar organisms together through a process called TAXONOMY.

Following are the roles of the digestive, excretory and endocrine systems in terms of homeostasis:

Explanation:

Role of Endocrine System:

The endocrine system mediates all the chemical signaling in the body.

Hormones are chemical messengers that the endocrine system uses to maintain chemical homeostasis.

Endocrine system manages glucoregulation by controlling the secretion of the hormones glucagon and insulin by the pancreas. Low and high blood sugar levels are sensed by the brain which then signals the endocrine system to release glucagon and insulin respectively.

The endocrine system is also indirectly involved in thermoregulation. A low core temperature signal received by the hypothalamus initiates the release of TSH by the pituitary gland and then that of T3, T4 thyroid hormones that stimulate shivering thermogenesis in the skeletal muscles.

Role of Digestive System:

The digestive system regulates the amount of nutrients absorbed in the body.

Although the absorption of nutrients in food is not exactly according to bodily needs, the absorption of dietary iron and calcium is strictly regulated by the digestive system.

Role of Excretory System:

The excretory system carries out osmoregulation which is the maintenance and regulation of water and salt levels in the blood.

The excretory system regulates the excretion of toxic waste from the blood.

Excess water, salts, urea and bilirubin (produced as a result of RBC break down) are some of the excretions.

please mark me as brainliest

Answer:

Following are the roles of the digestive, excretory and endocrine systems in terms of homeostasis:

The endocrine system regulates the secretion of various hormones and homeostatic mechanisms in response to signals of the hypothalamus and pituitary glands.

The excretory system maintains homeostasis by purifying the blood and getting rid of toxic waste from the blood.

The digestive system is mainly involved in the transfer and regulation of nutrients from food.

Answer:

1) The word ‘evolution’ was first mentioned in the book ‘The Origin of Species’ in 1859, by Charles Darwin. Darwin put forward the concept of evolution during his journey to the Galapagos Islands. 

2)Natural selection is an important mechanism of evolution. It states that the organisms that are able to survive and reproduce with the changing environmental conditions are selected by nature while the ones that cannot survive are eliminated.

3) Evolution mainly deals with the origin of life on earth. The conditions and the forms of life on earth were entirely different from what we see today.

please forgive me I cant answer 4th one..

5)Charles Darwin, an English naturalist of the 19th century made an extensive study of nature for over 20 years. 

1. The fossil record provides crucial evidence for biological evolution. Fossils are the preserved remains or traces of past organisms, providing a record of life on Earth over millions of years.

By studying fossils, scientists can observe changes in organisms and their characteristics over time. Fossils show a progression of simpler life forms in older layers to more complex ones in more recent layers.

2. Natural selection is a mechanism for biological change because it leads to the adaptation of populations to their environments over time. It is based on the concept that individuals within a population exhibit variation in traits, and those traits that enhance survival and reproduction are more likely to be passed on to future generations.

Through natural selection, individuals with advantageous traits have higher chances of surviving and reproducing, leading to the increased frequency of those traits in subsequent generations.

3. Chemical evolution, also known as abiogenesis or prebiotic evolution, explains the origin of life on Earth by proposing that life arose from non-living matter through a series of chemical reactions.

According to this theory, in Earth's early conditions, simple organic molecules formed from inorganic compounds through processes like lightning, volcanic activity, and reactions in the atmosphere and oceans.

These molecules then underwent further reactions, leading to the formation of more complex molecules like amino acids and nucleotides, which are the building blocks of proteins and nucleic acids, respectively.

4. Scientific theories such as biological and chemical evolution represent the strongest explanations for the changes observed in the fossil record because they are supported by extensive evidence from multiple scientific disciplines.

These theories have withstood rigorous testing, scrutiny, and peer review over many years. They are based on a large body of evidence, including the fossil record, comparative anatomy, genetics, molecular biology, and observations of natural populations.

5. Scientific theories on evolution and the fossil record can change over time as new evidence is discovered, technologies advance, and scientific understanding improves.

The process of scientific inquiry involves continuous investigation, testing, and refinement of theories based on new data and observations.

As scientists gather more evidence from fossil discoveries, genetic studies, experimental research, and other fields, our understanding of evolution and the fossil record can deepen and evolve.

If tRNA does not bring back the appropriate amino acids, the protein may fold incorrectly. so, the blank is tRNA.

The type of RNA that helps in the synthesis of proteins from mRNA, called as tRNA. tRNA acts as an adapter molecule during the translation process, and as an adapter, it connects amino acids to nucleic acids. It carries the amino acids that are added to the peptide chain and decodes the same codons in the mRNA molecule.  

The structure of tRNA can be separated into primary, secondary and tertiary structures. The structure tRNA has four arms (the acceptor, D, anti-codon and -arms), three loops (D, anti-codon and -loop) and a variable region.

It binds amino acids to specific codons present in the mRNA, by acting as an adapter. Therefore, If tRNA bring wrong amino acid to ribosome for assembly of protein, protein may fold incorrectly.

The planet pluto originally was considered as a real planet until its demotion as a dwarf planet.

Genetic recombination is most closely associated with: Choice D: Viral replication in host cells

Definition:

Genetic recombination (otherwise termed genetic reshuffling) is simply the exchange of genetic material between different organisms which leads to production of offspring with combinations of traits that differ from those found in either parent.

In retroviruses, recombination actually occurs at the point during replication when the retrovirus genome is in a DNA form and takes place by the same break-rejoin technique as in cells and DNA viruses.

Recombination can occur both between two related retroviruses and between the retrovirus DNA and the host DNA.
