4.index fossils, intrusions, and cross-cutting relationships

Explanation:

There are various geologic features or phenomenon that determines the relative ages of rocks . This geologic features or events includes index fossils , intrusions, cross cutting relationship etc. Note relative ages of rock does not give the actual ages oft the rocks but instead compares the ages of these rocks. Knowing the relative ages of rocks, one can decipher which rock is older or which one is younger. The geologic features give details on the sequence of event that happens through the formation.

Like the principle of cross cutting relationship states that the geologic feature which cut across or intrudes another geologic feature is younger than it surrounding rock.

Index fossils are remains of organisms that are widely spread. The deposition of this remains can give the sequence for deposition of the surrounding rocks which these fossils are found.

Intrusions occurs when geologic features like plutons invades another rock body. Geologically, the plutons will be younger than the surrounding or host rock.

The correct list of three different geologic features that help scientists determine the relative ages of rocks by their position is option 4, "index fossils, intrusions, and cross-cutting relationships".

Index fossils are used by geologists as clues to determine the age of rocks. These fossils are useful because they contain the remains of certain organisms, which scientists can relate to a specific period in time, thus offering clues as to the age of the rocks that surround them.

Intrusions are when magma dries and forms its own layer above other rocks. Scientists use these as clues as to the age of the other rocks because whenever this happens, we can know that the dried magma is younger than the surrounding rocks.

Finally, cross-cutting relationships are when one form of rock cuts through the layers of other rocks, this follows a geological rule which states that the cross-cutting rock will be younger than the others, offering yet another clue to the age of the rocks.

For these reasons, the correct list of geologic features that help scientists determine the relative ages of rocks by their position is option 4, "index fossils, intrusions, and cross-cutting relationships".

Body fluids are located within regions called "compartments in the body", each with a potentially different composition.

Body fluids are located within regions called compartments in the body, each with a potentially different composition.

These compartments include intracellular fluid, extracellular fluid, and various specific locations such as the bloodstream, lymphatic system, and cerebrospinal fluid, among others.

The location of body fluid can vary depending on the type of fluid and its function. For example, blood is located in the circulatory system, while urine is located in the urinary system.

Each compartment may have a potentially different composition due to variations in the types and concentrations of ions, proteins, and other molecules present. This is important for maintaining proper fluid balance and ensuring that the body's physiological processes can function properly.

A gene for microtubule proteins is being made in a cell. The mRNA representing an exact copy of that gene is put together using base pairing rules.

Gene expression is the process by which genetic information carried by DNA is converted from genes via messenger RNA to proteins.

mRNA is the molecule that links genes to proteins. The mRNA is formed through the process of transcription from a gene strand. The mRNA is then translated into protein by the joint action to transfer RNA and the ribosome.

mRNA therefore, serves as a temporary copy of information found in the DNA. Thus, mRNA represents an exact copy of the gene and it is put together using base pairing rules.

If the e and f genes are expressed, the Xi chromosome will be prevented from reaching 100% frequency if XsXs flies have the **highest fitness** of any genotype.

The expression of the e and f genes on the X chromosome is responsible for the phenomenon of meiotic drive, where one allele is preferentially transmitted to the next generation at the expense of the alternative allele. If XsXs flies have the highest fitness of any genotype, then they will be selected for and will produce more offspring, which will counteract the drive of the Xi chromosome. This will prevent the Xi chromosome from reaching 100% frequency in the population. The fitness of other genotypes, such as XiY and XsY or XiXs and XsXs, will not have an effect on the prevention of the Xi chromosome from reaching fixation.

Answer:

#2 & #3

Explanation:

both have the same amino acids. like leucine

Knowing that more than one codon codes for the same amino acid during protein building, we can affirm that sequences #2 and #3 code for the same protein.

During protein synthesis, the ribosome reads mRNA molecules from the 5' to 3' extremes.

While doing it, tRNA recognizes the codons of the molecules and adds the correct amino acids.

Codons are short sequences of three nucleotides that code for one amino acid.

So the sequence of codons determines the sequence of amino acids in the building protein.

There are 64 possible codons,

Knowing this, we can build the protein by reading the mRNA sequences.

Split-brain patients have undergone a surgery that severs the corpus callosum, the band of fibers that connects the two hemispheres of the brain. This means that information received through the right senses (ear, eye, or side of the body) is processed by the left hemisphere and vice versa. The correct answer is c)Speak about info received exclusively in their left hemisphere.

Split-brain patients are unable to speak about information received exclusively through their left hemisphere because that information cannot be transferred to the language centers in the left hemisphere for verbal expression. However, they can perform tasks that involve integrating logical and spatial information because both hemispheres are still able to process information independently. They may also have difficulty coordinating movements between major and minor muscle groups, but this is not a specific symptom of split-brain syndrome.

An allele is a normal variation of a specific gene. An allele can be any of the numerous alternative forms of a gene that arise by mutation and are located in the same position on a chromosome.

An allele is a variant of a gene, a unit of hereditary information located on a particular position of a chromosome. A single gene can have several different alleles. Because we inherit two copies of each chromosome, we also receive two copies of each gene.

A normal variation of a particular gene is the definition of an allele. Hence, Option (C) is the correct option: an allele is a normal variation of a specific gene.

The part of the brain where habits are formed, known as the basal ganglia, can be activated by events that are rewarding, exciting, unexpected, intense, and cues from the environment associated with those events. The basal ganglia plays a crucial role in habit formation and reinforcement learning. When we engage in behaviors that are associated with positive outcomes or rewards, the basal ganglia is involved in encoding and reinforcing those habits. Similarly, cues from the environment that are linked to rewarding experiences can trigger the activation of the basal ganglia and influence habit formation. Therefore, the statement is true.

Answer:

antigen-antibody interaction.

Explanation:

An anaphylactic reaction also known as anaphylaxis can be defined as a severe short-term allergic reaction that usually occurs within seconds or minutes after being exposed to an allergen.

Basically, an anaphylactic reaction is potentially life threatening i.e it is capable of causing death to patients and as such a medical diagnosis is required and it must be treated by a medical professional (expert) immediately after exposure to an allergen.

Hence, an anaphylactic reaction occurs because of an antigen-antibody interaction.

An epinephrine (adrenaline) may be quickly administered (given) to the patient by the medical professional.

Some of the symptoms of an anaphylactic reaction are;

I. Running nose and sneezing.

II. Skin rash.

III. Dizziness, fainting, vomiting, paleness, diarrhea etc.
