What are the vestigal organs present in human body??
Answer:
Charles Darwin listed a number of putative human vestigial features, which he termed rudimentary, in The Descent of Man (1871). These included the muscles of the ear; wisdom teeth; the appendix; the tail bone; body hair; and the semilunar fold in the corner of the eye.hope it's helpful .!pls mark me in brainlistIn this experiment, you are looking at the effect of various germicides on microbial growth. The organism that you are using for this experiment is baking yeast, which is a eukaryote. Do you think that this organism would be more or less susceptible to the various germicides than a prokaryotic organism, such as bacteria?
Answer:
Less susceptible.
Explanation:
This organism would be less susceptible to the various germicides than a prokaryotic organism, such as bacteria because the form and structure of eukaryotic organism is different from the prokaryotic organism so the germicides no or less affected the eukaryotic organism so we can say that the the eukaryotic organism which is used in baking would be less susceptible to the various germicides than a prokaryotic organism.

Answer:
This question lacks options, options are:
A) glial cell
B) interneuron
C) sensory neuron
D) motor neuron.
The correct answer is D.
Explanation:
The brain sends instructions to the muscles that control voluntary movement through nerve cells called motor neurons. The function of the motor neuron is basically to carry the information that comes from the descending pathways of the spinal cord, in order to generate an activation in the tissues of the skeletal and visceral muscles of all parts of the body. Motor neurons need the information sent to them by sensory or efferent neurons. Since in order to perform the appropriate muscle movements for the situation, our brain must receive information from the outside. By sending sensory stimulation through interoreceptors, motor neurons can regulate visceral activity, stimulating or inhibiting the activity of their effector tissues. In this way, our nervous system integrates the information from both types of neurons and allows us to move and react according to the demands and circumstances of our external context.

White a paragraph comparing the organices in a to the organs in your body.
Answer:
An organ is a part of the body of a living organism perform a specific role in the body such as the stomach, the liver and many more. Organelles on other hand are like organs of the cells that are contained in the cytoplasm of cell these also have a certain specialized roles to play for the cell, and they all depend on each other. The example of the organelles are nucleus, mitochondria and many more.
* Organelles are structures inside the cytoplasm of cells
* Organs are amde up of tissues composed of group of specialized cells that, has a particular role in the body
characteristics between invertebrates and vertebrates in a tabular form.
Answer:
Invertebrates: Do not possess a backbone and doesn't have an internal skeleton. Has an exoskeleton. Are generally smaller than vertebrates. Possess an open circulatory system. The majority have compound eyes. Includes radial or bilateral body symmetry. Presence of a simple and unorganized nervous system. Mode of nutrition includes Autotrophic, Parasitic, and Heterotrophic. 95% of animal species are invertebrates. Flatworms, arthropods, sponges, insects are few examples of Invertebrates.
Vertebrates: Possess a backbone and has an internal skeleton. Does not have an endoskeleton. Larger than invertebrates. Possess a closed circulatory system. Do not have compound eyes. Has bilateral body symmetry. Presence of complex and highly specialized organ systems with specific functions. The mode of nutrition is usually heterotrophic. 5% of animal species are vertebrates. Mammals, fish, reptiles, amphibians, and birds are examples of Vertebrates.
The second generation of purebred cross of -hom-ozygo us recessive organism, with a —hom-ozygous dominant organism, contain a ratio of approximately _______ expressed dominant traits to recessive traits.
A. 2:1
B. 1:1
C. 1:3
D. 3:1
Answer:
D. 3:1
Explanation:
Gregor Mendel, in one of his numerous studies, performed a cross between purebred dominant (TT) pea plants and purebred recessive (tt) pea plants. All the offsprings of this cross appeared heterozygous tall (Tt) in the F1 generation.
However, when he self-crossed the F1 generation i.e. Tt × Tt, Mendel obtained a phenotypic ratio of 3 tall plants (dominant traits) : 1 short plant (recessive). This showed that the masked gene (recessive) was still present.

One way in which a virus gains control of a cell is to direct the synthesis of new viral proteins. Therefore, the synthesis of mRNA is a central issue for all viruses. How does a retrovirus like HIV that causes AIDS achieve this goal
EVOLUTION CONNECTION The history of life has been punctuated by several mass extinctions. For example, the impact of a meteorite may have wiped out most of the dinosaurs and many forms of marine life at the end of the Cretaceous period. Fossils indicate that plants were less severely affected by this mass extinction. What adaptations may have enabled plants to withstand this disaster better than animals
Answer:
Dissaster like meteorite impacted all type of living forms, however, animals are impacted the most and plants are impacted least. It is possible due to ability of plants to prepare their food on their own as they are autotrophic and use photosynthesis. The raw material for preparing these are easily available that are sunlight, CO2 and water.
They are not depende on other for their cellular respiration. The other major reason is that the Plant seeds can remain dormant in unfavorable conditions for many years in the soil. The roots always provide nutrition even the stems get effected.
Decide whether the following statement is TRUE or FALSE.
A symporter would function as an antiporter if its orientation in the membrane were reversed (that is, if the portion of the protein normally exposed to the cytosol faced the outside of the cell instead).
Answer:
False
Explanation:
Uniporters, symporters, and antiporters are membrane proteins that transport substances across cell membranes. Uniporters are proteins that carry one specific ion or molecule. Moreover, symporters are carriers that transport at least two substrates/solutes in the same direction, i.e., from one side of the membrane to the other at the same time. On the other hand, antiporters are carrier proteins that catalyze the exchange of two substrates/solutes (ions or molecules) in opposite directions at the same time. In consequence, turning around a symporter would not convert it into an antiporter, only would cause the symporter to bind two solutes on the opposite side of the membrane.

Intercostal nerves Group of answer choices are also known as cervical nerves. do not enter into a plexus and directly connect to the structures they supply. are found in the C6-T4 area of the vertebral column. extend through the sacrum. do not exist in humans.
Answer:
The correct answer is: do not enter into a plexus and directly connect to the structures they supply.
Explanation:
The anterior rami of the thoracic spinal nerves from T1 to T11 give birth to the intercostal nerves, which are part of the somatic nervous system.
The intercostal nerves supply the thoracic pleura and abdominal peritoneum, and they vary from the anterior rami of the other spinal nerves in that they each take their own path without forming a plexus, directly connecting to the structures they supply.
The intercostal nerves are derived from the somatic nervous system, unlike the autonomic nervous system nerves that innervate the visceral pleura of the thoracic cavity. They can govern muscle contractions and give sensory information about the skin and parietal pleura as a result of this. This explains why damage to the thoracic cavity's interior wall can be felt as a severe discomfort in the damaged area. Damage to the visceral pleura causes a pain that is not localized.

Explanation:
What do you think will happen to the convention currents in the mantle if the interior of Earth eventually cools down
Answer:
No convention currents occur.
Explanation:
If the interior part of the Earth is cool down, it will leads to convection currents to stop. Due to this cool down of the earth's interior part cease the motion of the plates and the Earth would become geologically dead. Convection currents within the Earth's mantle occurs when the hot material rising upwards and then dropping back toward the core due to cooling so if the mantle is cool so no movement occurs as well as no convention currents.

In a study involving a cell-free translation system from coli, the polyribonucleotide AUGUUUUUUUUUUUU directs the synthesis of the oligopeptide fMet-Phe-Phe-Phe-Phe. In the presence of a new class of translation-targeting antibiotics that bind to the large ribosomal subunit, the ribosomal complex forms, the initiator tRNA binds the mRNA, the second tRNA enters the A site of the ribosome, but no peptide bonds form. Which of the following is a likely function of these new antibiotics?
a. Blocks peptidyl transferase activity
b. Inhibits tRNA aminoacyl synthetase function
c. Inhibits ribosomal translocation along the mRNA
d. Prevents anticodon base-pairing with the codon
e. Blocks binding of the Shine-Dalgarno box to the rRNA
Answer:
c. Inhibits ribosomal translocation along the mRNA.
Explanation:
Initiator tRNA is thought to bind directly to P-site of small ribosomal sub unit. These tRNA are positioned at P site and remain attached to tRNA located at this site. Initiation factor helps to mediate this event.

which is an example of incomplete dominance?
a] A red flower and a yellow flower mating to produce a yellow flower.
b] A red flower and a yellow flower mating to produce a red flower.
c] A red flower and a yellow flower mating to produce an orange flower.
d] A orange flowers mating to produce an orange flower.
Answer:
c] A red flower and a yellow flower mating to produce an orange flower.
Explanation:
An incomplete dominance in biological terms means a situation where one allele doesn't totally take the expression in a gene, but rather the two parental traits combine to form a secondary trait. As a result of this, a third phenotype comes up, with the physical trait being a mix of the phenotype of the parents.
Therefore, an example of incomplete dominance is a red flower and a yellow flower mating to produce an orange flower.
Answer:D
Explanation:
D is a Orange with orange meaning its incomplete dominance because it both the same theres no other color dominance the other
