Explanation:

Taxonomy is the science of naming and classifying organisms based on structural and genetic evidence. It's a critical component of biology, helping to organize the evolutionary history of organisms. The modern taxonomic systems use genetic methods for a more precise classification.

Taxonomy is the science of naming and classifying organisms based on structural comparisons and genetic evidence. Swedish botanist Carolus Linnaeus was a key figure in the establishment of this system.

Taxonomy is a critical component of biological studies. It helps organize humans and their evolutionary ancestors, both spatially and temporally. Two types of evidence focused on in taxonomy are morphologic (form and function) and genetic.

In the modern era, genetic methods have become a standardized way to compare all living organisms, providing a more defined and accurate classification system. These methods have become integral to the science of taxonomy.

Organisms that share similar physical features and genomes are usually more closely related. Such overlapping features, known as homologous structures, stem from developmental similarities that are based on evolution.

Transcription begins when RNA polymerase binds to the promoter of the gene. It then works to assemble RNA nucleotides into a strand that complements the DNA template, till it reaches a termination sequence.

For transcription to begin in a cell, the first thing that needs to occur is that RNA polymerase attaches itself to the promoter of the gene. The promoter is a specific DNA sequence that indicates where the process of transcription should start. The RNA polymerase is an enzyme that carries out the process of transcription, forming a new mRNA molecule by reading the DNA strand.

Answer:

The 3 types of muscle tissue are cardiac, smooth, and skeletal.

Explanation:

Cardiac: Cardiac muscle cells are located in the walls of the heart, appear striated, and are under involuntary control.

Smooth: Smooth muscle (so-named because the cells do not have striations) is present in the walls of hollow organs like the urinary bladder, uterus, stomach, intestines, and in the walls of passageways, such as the arteries and veins of the circulatory system, and the tracts of the respiratory, urinary, and reproductive

Skeletal: Skeletal muscle is found between bones, and uses tendons to connect the epimysium to the periosteum, or outer covering, of bone.

Final answer:

The three types of muscles in the human body are skeletal muscles for voluntary movement, smooth muscles in internal organs for involuntary functions, and cardiac muscle found only in the heart. They differ by striation, control, and location.

Explanation:

The human body has three major types of muscle tissues: skeletal, smooth, and cardiac muscles. Each type has distinct characteristics and locations within the body.

Skeletal Muscles

Skeletal muscles are attached to bones and are responsible for voluntary movements. These muscles display a striped, or striated, appearance under a microscope and are usually under conscious control. Examples include the biceps and quadriceps

Smooth Muscles

Smooth muscles are found in the walls of internal organs such as the stomach, intestines, and blood vessels. They control involuntary movements and do not show striations, appearing smooth under a microscope.

Cardiac Muscle

The cardiac muscle is specialized muscle tissue found only in the heart. It is striated like skeletal muscle but operates involuntarily, controlling the heartbeat.

Striated muscles: Skeletal and cardiac muscles

Non-striated muscle: Smooth muscle

Voluntary muscle: Skeletal muscle

Involuntary muscles: Smooth and cardiac muscles

Answer: 4 : 0  (long spines to short spines)

Explanation:

Dominant allele: L

Recessive allele: l

When is there at least one dominant allele in the phenotype it shows the dominant trait (long spines)

There has to be two recessive alleles to make the phenotype the recessive trait (short spines).

Therefore since there is one L in every box, all of the offspring will show the dominant trait (long spines).

Explanation:

Geothermal energy is a practical, renewable energy source that works best when magma pools are close to the Earth's surface. Contrary to the false statement, it is most effective in volcanically active areas.

In assessing the statements about geothermal energy, the untrue statement is: a. it is not a practical source of energy. In reality, geothermal energy is highly practical, particularly in regions where volcanic activity or other heat sources exist near the Earth's surface. Geothermal energy is a renewable source of energy because it is constantly replenished by the heat generated by the Earth's core. This heat is used to produce steam, which then powers turbines to generate electricity. Geothermal energy works best when the magma, or molten rock, pool is close to the Earth's surface, making statement c is also correct. Therefore, geothermal energy is not only a practical source of energy, but it is also renewable and advantageous in certain geographical settings, particularly those that are volcanically active (statement b).

Answer:

Plants, animals, factories.

Explanation:

Plants and animals are living organisms that undergoes aerobic respiration that takes in Oxygen and released carbon dioxide.

Do not be mislead that plants do not give out CO2. During the night, when rate of photosynthesis is slower than rate of respiration, CO2 is released to the atmosphere and acts as a source of CO2.

Animals can only respirate and not photosynthesize. Hence, it is definitely a source of CO2

Factories are sources of CO2 assuming that their operations releases CO2 as by-product which is a very probable event for most factory operations.

Sunlight is a abiotic factor that does not cause CO2 to be released on its own to act as a source of CO2 in the atmosphere.

Plants, animals, and factories are sources of carbon dioxide in the atmosphere.

Plants, animals, and factories are significant sources of carbon dioxide emissions into the Earth's atmosphere. Plants play a dual role in the carbon cycle. During photosynthesis, they absorb CO2 and convert it into oxygen (O2) and organic carbon compounds, helping regulate atmospheric CO2 levels. However, when plants decay or burn, they release CO2 back into the atmosphere.

Animals, through respiration, release CO2 as a byproduct of metabolism. This carbon comes from the food they consume, and when they exhale, it contributes to atmospheric CO2 levels. Factories, particularly those burning fossil fuels for energy and industrial processes, release substantial amounts of CO2 as a result of combustion. These human activities significantly impact global carbon levels and contribute to climate change and global warming. Sustainable practices and reduced emissions are critical to mitigate these effects.

Final answer:

The proportion of F2 progeny with the allele for wrinkled skin is expected to be 1/4 when considering a dihybrid cross of two heterozygous pea plants. This is based on the principles of Mendelian genetics and the monohybrid 3:1 ratio characteristic of a single trait with one dominant and one recessive allele.

Explanation:

When considering a dihybrid cross and determining the proportion of progeny that carries an allele for a specific trait such as wrinkled skin in peas, we utilize the principles of Mendelian genetics, particularly the concept of independent assortment and dominance.

For the trait of seed texture, the allele for wrinkled skin in peas is recessive, typically represented as 'r'. In a dihybrid cross of two heterozygous F1 plants (RrYy), we expect to see a phenotypic ratio of 9:3:3:1, which can be broken down into two separate monohybrid 3:1 ratios, one for each trait. Thus, considering only the texture, three-quarters of the F2 offspring will display the dominant round phenotype (R_), and one-quarter will display the recessive wrinkled phenotype (rr). This is because the proportion of F2 progeny with wrinkled skin (homozygous recessive condition rr) is expected to be 1/4, as determined by the product of the probabilities for each independent event: (1/4) × (1/4).

Answer:

mm

Explanation:

the only way for it to be recessive, is to remove the dominant

The genotype for a recessive offspring in this scenario is 'mm,' as this reflects the presence of two copies of the recessive allele required for the recessive trait to be expressed.

The genotype for a recessive offspring, when "M" represents the dominant condition and "m" represents the recessive condition for a trait, would be mm. This is because a recessive trait is only expressed when an individual has two copies of the recessive allele.

Therefore, for the offspring to display the recessive trait, both alleles must be m, resulting in the homozygous recessive genotype mm. Genotypes are often abbreviated using a single letter, with the dominant trait typically indicated by a capital letter and the recessive trait by a lowercase letter. In cases where "B" represents a dominant black allele and "b" a recessive brown allele, the parallel is that a recessive brown offspring would have the genotype bb.

Through sunspots that are centers of high magnetic field, that have 11 year cycles.

Explanation:

In the Sun, the flows of hot plasma in the convection zone create the solar magnetic field. This is sustained by nuclear fusion in the Sun. Sunspots are regions of very strong magnetic field that are perceptible on the Sun's surface or photo-sphere. The number of sunspots on the sun increase and decrease over time in a regular, approximately 11-year cycle, which is, in fact the solar magnetic activity cycle.

The answer is 4. basalt.

Here's why:

Location B is at the Mid-Atlantic Ridge. This is a divergent plate boundary, where plates are moving apart and magma is rising from the mantle.

Magma that rises at the Mid-Atlantic Ridge is basaltic. Basalt is a fine-grained, dark-colored igneous rock formed by the rapid cooling of magma.

Granite and rhyolite are not typically found at Mid-Atlantic Ridges. They are felsic igneous rocks, which are lighter in color and coarser-grained than basalt. They are more commonly found in continental settings, where magma cools slowly underground.

Conglomerate is a sedimentary rock. It is formed from the erosion and deposition of other rocks, not from the cooling of magma.

Therefore, based on the location and the type of rock formation that occurs at Mid-Atlantic Ridges, the rock samples taken from location B would most likely be composed of basalt.

The diagram below shows a portion of earths crust near the mid Atlantic ridge. Letters A B C D and E represent locations on the sea floor. Rock samples taken from location B would most likely be composed of

#SPJ2

Both of the female's parents would've had to give her a recessive X chromosome in order for the allele to be expressed.

Final answer:

A female needs two copies of a recessive X-linked allele to express the associated trait, receiving one from each parent. Carrier females possess one mutant allele and one dominant allele, potentially exhibiting mild symptoms due to X chromosome inactivation.

Explanation:

For a recessive X-linked allele to be expressed in females, they must inherit two copies of the allele, one from each parent. If a female inherits just one recessive X-linked allele, she will be a carrier of the trait, but typically unaffected. This phenomenon is due to the fact that females have two X chromosomes, enabling them to carry a recessive allele without expressing the trait, provided their other X chromosome carries a dominant allele. However, carrier females have a chance of manifesting mild forms of the trait because of the random inactivation of one X chromosome in each cell, which could lead to cells expressing the recessive allele.

Examples of human sex-linked disorders include red-green color blindness and hemophilia. Males, who have only one X chromosome, will express the trait if they inherit one mutant X allele. In contrast, females must receive one recessive allele from each parent. As a result, X-linked recessive traits are more frequently seen in males than in females.
