Answer:
B. Metabolism
Explanation:
Viruses cannot make food, take in food, or produce waste
All of the characteristics listed are true for viruses except for b) metabolism.
What is a virus?A virus is a non-living infectious agent that can only replicate inside the host cell. They are extremely small and can only be seen under an electron microscope. Viruses are composed of genetic material (DNA or RNA) enclosed in a protective protein coat called the capsid. They do not have the ability to replicate or survive on their own and rely on host cells to provide the necessary metabolic machinery to replicate
Viruses are ultramicroscopic in size and do not have a definite shape. Viruses also infect host cells and utilize the host's metabolic machinery for replication. Viruses lack a metabolism of their own, and are thus not considered living organisms.

Imagine that, of three species, it is known that species 1 and 3 were separated 10 million years ago, based on geologic measurements. Genetic analysis at a neutral locus indicates that these species differ by 100 substitutions. If there are 10 substitutions separating species 1 and 2, approximately how long ago did these species diverge?.
(C) 1 million years ago is the approximate time that the species diverge. This is because Genetic analysis at a neutral locus indicates that these species differ by 100 substitutions. If there are 10 substitutions separating species 1 and 2.
Divergence in evolutionary biology refers to an evolutionary process in which a population of an inbreeding species splits into two or more descendant species that have progressively diverged in their morphologies and structural characteristics.
The difference between species 1 and 3 is 100 substitutions, and humans split off 10 million years ago. As a result, there will be 10 substitutions in a million years. As a result, 1 million years ago, species 1 and 2, which are divided by 10 substitution, diverged.

Darwin called the units of inheritance that pass traits from parents to offspring.
Darwin called the units of inheritance that pass traits from parents to offspring gemmules.
Charles Darwin proposed the pangenesis theory to describe the units of inheritance between parents and offspring. The minute particles of inheritance that are derived from parent cells were referred to as gemmules. His theory suggested that these gemmules can be modified in any part of the body and are transferred into the reproductive organs of the parents. The gemmules then are transferred to the offspring.
As of now, Charles Darwin's theory is replaced by the chromosomal theory of inheritance, and the concept of gemmules is replaced by that of genes. A theory of inheritance of acquired characteristics (IAC) was further considered by Darwin from which he explained the concept of gemmules.

Which brain structure receives information from all the senses except smell? hippocampus amygdala pons thalamus
Brain structure that receives information from all the senses except smell is known as the thalamus.
Thalamus is a central, egg-shaped region in the human brain. It serves as a relay station including all incoming listening, taste, vision, and sensation (but not smell) sensory inputs from the body to the brain.
A specialized brain structure located deep within the temporal lobe is the hippocampus. It plays a significant part in memory and learning. It is a flexible and delicate structure that is responsive to many stimuli. According to studies, it is also impacted by a number of neurological and mental problems.

In _____linked glycoproteins, the sugar can be attached to the protein by a bond to lysine
In N-linked glycoproteins, the sugar can be attached to the protein by a bond to lysine.
N-linked protein glycosylation of proteins occurs in all three domains of life. The pathway at the periplasmic membrane of prokaryotes and the process at the ER membrane are considered to be homologous . The high conservation of the process across all domains of life makes it possible to identify the underlying principles of the pathway and to develop general concepts of N-linked protein glycosylation.
The assembly of an oligosaccharide on an isoprenoid lipid (bactoprenol in the bacterial systems and dolichol in archaea and eukaryotes) from nucleotide activated monosaccharides on the cytoplasmic side of the membrane by a set of specific glycosyltransferases and the subsequent translocation of the lipid-linked oligosaccharide is a unifying scheme in all systems.
In eukaryotes, the oligosaccharide is further extended by lumen-oriented glycosyltransferases, but these enzymes use dolichylphosphate-bound monosaccharides as substrates. The acceptors of the oligosaccharide are selected asparagine residues of polypeptide chains that have entered the periplasm or the lumen of the ER, respectively. Oligosaccharyltransferase, the central enzyme of the N-glycosylation pathway, catalyses the formation of an N-glycosidic linkage of the oligosaccharide to the side-chain amide of asparagine residues that are specified by the consensus sequence N-X-S/T.

The correct option is (a) To measure the amount of rainfall
A rain gauge is a meteorological device used to gauge how much rain falls over a specific area in a specified amount of time.
What is rain gauge and what is its function? The oldest known meteorological instruments are rain gauges, which are considered to have been in use in India more than 2,000 years ago. Simply put, a rain gauge is a cylinder that collects rain. An inch of rain has fallen if there is an inch of accumulation in the cylinder. It's that easy. The majority of common rain gauges feature a large funnel leading into the cylinder and are calibrated so that when rain collects within, one inch of rain equals one-tenth of an inch. The cross-sectional area of the funnel is ten times that of the tube. With this device, rainfall as little as.01 inches can be measured.

Answer:
All of the above. I think this is the answer.
the sense of equilibrium maintains the stability of the head and body when they are motionless. the sense of equilibrium balances the head and the body when they are suddenly moved or rotated.
The sense of static equilibrium maintains the stability of the head and body when they are motionless. The sense of dynamic equilibrium balances the head and the body when they are suddenly moved or rotated.
Static equilibrium occurs when a body is at rest. There are two forces acting upon the body during static equilibrium, but they occur in opposite direction, and as a result the body remains static. For example, when an organism stands still in its position, it is acted upon by the force of gravity downwards and normal force upwards and thus remains in static equilibrium.
Dynamic equilibrium occurs when a process is going on. It detects the angular acceleration of the movement of head. In humans, the semicircular canals help in maintaining the dynamic equilibrium.
