you could use to describe a cockroach
Do not answer if you don’t know I will report your “answer”
Answer and Explanation:
A few characteristics shared by all cockroach species might be useful to identify them.
Their body shape is flattened, wide and oval. Pronotum: There is a big plaque joined to the thorax, composed of three segments. The first segment covers and protects the small head.Head: Small heads carrying two typical long, thin, and flexible antennae used to sense the environment. They also have two big composed ocellus or eyes. The oral structures are adapted to bite, chew, and absorb. Abdomen: The abdomen is composed of 10 segments. Exoskeleton: Their whole body is covered by a hard, resistant exoskeleton, covered with a cerous substance. Receptors: They have many thermal, tactile, and gustatory receptors to sense the environment. Wings: Two pairs of wings. The tegmens are the hard front pair that protects the body and the second pair of wings. The second pair is membranous and used to fly. Legs: Three pairs of robust legs joined to the thoracic segments. The last pair of legs are much longer than the others. All of them have ornaments that look like spines, and might have a sensory function and help the insect to displace through different fields.What is the dental formula of a cow
Write down the functions of
1.microtubules
2.tripletsof microtubules
Answer:
Microtubules are filamentous intracellular structures that are responsible for various kinds of movements in all eukaryotic cells. Microtubules are involved in nucleic and cell division, organization of intracellular structure, and intracellular transport, as well as ciliary and flagellar motility
Centrioles are cylindrical structures that are made up of protein tubes called microtubules. Specifically, nine groups of three microtubules, known as triplet microtubules, are linked together to make the walls of the cylinder.
Hope it helps :)
Answer:
Microtubules have several functions. For example, they provide the rigid, organized components of the cytoskeleton that give shape to many cells, and they are major components of cilia and flagella (cellular locomotory projections). They participate in the formation of the spindle during cell division (mitosis).
triplet microtubules are linked together to make the walls of the cylinder.

When Avery and McCarty were attempting to identify the substance involved transferring hereditary material, they tested the ability of a bacterial S cell extract to transform R cells after different components of the extract were degraded by enzymes. Which treatment inhibited the ability of the S cell extract to transform R cells
Answer:
D). DNA degrading enzymes
Explanation:
As per the question, the 'DNA degrading enzymes' is the treatment that has obstructed the S cell extract's potential to convert into R cells. The enzyme called 'deoxyribonuclease' functions to produce hydrolytic breakup that leads to the degradation of the DNA. It promotes the 'joining of the nucleotides to form the appropriate pairs by degenerating the molecules of the DNA that has pyrimidine dimers.' Thus, this is the reason due to which S cell is devalued before being transformed into the S cell as this DNase enzyme focuses on developing a new tract of efficient and correctly joined nucleotides. Hence, option D is the correct answer.

which water based animals have a mechanism to prevent water from diffusing into their bodies
Answer:
Osmoconformers are marine animals which, in contrast to osmoregulators, maintain the osmolarity of their body fluids such that it is always equal to the surrounding seawater. Osmoconformers decrease the net flux of water into or out of their bodies from diffusion.
Explanation:
Which of the following can be inferred from the genetic code?
A.All organisms have a common biochemical evolutionary origin.
B.Organisms can live without genetic code.
C.Four nucleotides.
D.Four nucleosides.
Answer:
A. All organisms have a common biochemical evolutionary origin.
Explanation:
Genetic code is the biological mechanism by which the DNA in our body is used to synthesize protein needed for growth and development. The genetic code comprises of all the possible 64 codons i.e. a group of three nucleotides that encode an amino acid.
One of the characteristics of the genetic code is that it is UNIVERSAL. This means that all known living organisms make use of the same genetic code and hence, this portrays that all living organisms share a common biochemical evolutionary origin.
What will be the impact on productivity of plant if CO2 reduction stops during photosynthesis?
Answer:
As carbon dioxide concentrations increase, the pores don't open as wide, resulting in lower levels of transpiration by plants and thus increased water-use efficiency.
Explanation:
Occasionally, plates like the ones inoculated as part of this exercise are allowed to remain in the incubator for extended periods of time (two weeks or more). When the plates are examined, the agar is desiccated and Halobacterium salinarium is seen growing on plates labeled 5% NaCl and 10% NaCl, despite the fact that H. salinarium requires a minimum of 13% NaCl for growth. Explain why this happens.
Answer and Explanation:
This happened because when the agar was desiccated, all the water was released, but the solutes used in the culture medium remained in the petri dish, that is, all the nutrients remained available to H. salinarium, which survived by consuming these nutrients. Although the growth of H. salinarium requires a higher level of NaCl than the level left in the petri dish, we can consider that some colonies of H. salinarium adapted to the low level of NaCl and managed to survive, passing this characteristic to new colonies.
How do scientists believe the Earth formed???????
Answer:
Formation. When the solar system settled into its current layout about 4.5 billion years ago, Earth formed when gravity pulled swirling gas and dust in to become the third planet from the Sun. Like its fellow terrestrial planets, Earth has a central core, a rocky mantle and a solid crust.
The "homunculus" constructed on the basis of somatosensory representations in the human primary somatosensory cortex
Answer:
The correct answer is -
a. has a grossly enlarged face and hands compared to torso and limbs
c. is distorted because of the disproportionate representation of certain body parts relative to others in the somatosensory cortex
Explanation:
" Homunculus" is a graphical representation of a small but fully grown man which the foetus is believed to develop whereas somatosensory homunculus is a neurological representation of the brain of humans that shows the motor and sensory functions of the body.
It has a large number of sensory nerves from the hand that take a large part of the brain. The face also has many nerve endings and are represented by large areas of the homunculus. A distorted look comes from this uneven representation of different body parts in the homunculus.

IN YOUR OWN WORDS, what is the definition for Zygote?
Answer:
Zygote, fertilized egg cell that results from the union of a female gamete (egg, or ovum) with a male gamete (sperm). In the embryonic development of humans and other animals, the zygote stage is brief and is followed by cleavage, when the single cell becomes subdivided into smaller cells.
Which of the following is an example of a
homologous trait?
A. the wings of bees and birds
B. the forearm of different animals
C. the DNA of land animals
Answer:
the wings on bees and birds
An example of a homologous trait is the wings of bees and birds. The correct option is A.
What are homologous traits?The Theory of Evolution can be used to explain the homologous features of related species. According to this hypothesis, species develop over time from a common progenitor.
In order to adapt to the new environment, species separated from one another and developed new features. The variety of species observed on Earth today is the result of a process known as speciation.
The homologous features that are shared by related species are proof of their shared ancestry. For instance, despite being different, the wings of a bat and a bird share characteristics.
Therefore, the correct option is A. the wings of bees and birds.

Why are genetically engineered mammalian cells sometimes needed to produce certain proteins instead of genetically engineered bacteria?
A. Mammal cells are larger and can produce greater volumes of protein.
B. Mammalian cells are not needed; bacterial cells can produce the same proteins as long as they have the gene that codes for it.
C. Mammal cells have more precise restriction enzymes.
D. Bacteria make proteins differently than mammals, and cannot make certain human proteins.
Answer:
C
Explanation:
As mammal cells have more precise restriction enzymes, it sometimes needed instead of bacteria. The correct option is C.
What is genetic engineering?Genetic engineering also referred to as genetic modification is a process that uses laboratory-based technologies to alter an organism's DNA makeup.
Because mammalian cells have more precise restriction enzymes, it is sometimes necessary to use them instead of bacteria.
Herbert Boyer and Stanley Cohen, biochemists, create genetic engineering in 1973 by implanting DNA from one bacteria into yet another.
There are three basic stepping stones to genetic engineering. These are:
Isolating DNA fragments from a donor organism.Inserting an isolated donor DNA fragment into a vector genome.Growing a recombinant vector in an appropriate host.Thus, the correct option is C.

Which of the following is NOT a stage in the cell cycle?
A. Gap 1
B. Gap 2
C. Development
D. Mitosis
Answer:
C. Development
Explanation:
The cell cycle involves two major kinds of division; mitosis and meiosis. These divisions is each composed of stages/phases. Mitosis, for example, is divided into: interphase and mitotic (M) phase.
The interphase stage consists of Gap 1 (G1) phase, Synthesis (S) phase and Gap 2 (G2) phase while the mitotic phase consists of mitosis and cytokinesis etc. Hence, according to the question, development is not a stage of the cell cycle.

what is the function of red blood cells in the circulatory system
Answer:
Red blood cells carry oxygen from our lungs to the rest of our bodies.
Explanation:
The function of the red cell and its hemoglobin is to carry oxygen from the lungs or gills to all the body tissues and to carry carbon dioxide, a waste product of metabolism, to the lungs, where it's removed from the body. In invertebrates, oxygen-carrying pigment is carried free in the plasma; its concentration in red cells in vertebrates, so that oxygen and carbon dioxide are exchanged as gases, is more efficient and represents an important evolutionary development. The mammalian red cell is further adapted by lacking a nucleus—the amount of oxygen required by the cell for its own metabolism is thus very low, and most oxygen carried can be freed into the tissues.
