Cells that primarily produce steroid hormones, such as testosterone and estrogen, have large quantities of.
Answer: Smooth endoplasmic reticulum
Cells that primarily produce steroid hormones, such as testosterone and estrogen, have large quantities of smooth endoplasmic reticulum.
Thus, Depending on whether ribosomes are present or not, the endoplasmic reticulum may be smooth or rough.
Small, spherical organelles called ribosomes produce the proteins that cells need.
They are also known as the cell's protein factories. Ribosomes are found in both bacterial and eukaryotic cells. The two forms of ER frequently give the impression of being distinct, yet they are actually parts of the same organelle, the endoplasmic reticulum.

Why does an analysis of all an animal’s genes reveal more about its classification than studying its visible features or behavior?
The analysis of all an animal’s genes reveals more about its classification than behavior because fine-tuning evolution is evidenced by homo-logous sequences.
What is sequence homo-logy?Sequence homo-logy refers to different nucleotide sequences that are similar due to a common origin.
Behavior may be due to the convergence of a feature in distinct lineages, but evolution is largely determined by homo-logy between gene sequences.

Two genes are 14 map units apart on the X chromosome. What percent of the father's gametes will be recombinant
Two genes are separated by 14 map units on the X chromosome. The percentage of the father's gametes that will be recombinant is 30%.
How is the recombination rate calculated?To assess the occurrence of the permutation, the rate of recombination between two genes is determined. As the ratio is multiplied by 100, the value expresses the percentage of recombinant gametes in the total gametes. Thus, if the recombinant gametes make up 30% of the total, the recombination rate is 30%.
With this information, we can conclude that Parental Gametes are formed even if there is no recombination and appear in greater numbers. Recombinant Gametes are formed only if there is an exchange and appear in smaller numbers.

They then examined the infected cells and found that they contained 32P which demonstrated that DNA is the phage's genetic material.
Scientists weren't sure if a cell's genetic material was made up of proteins or DNA until the middle of the 20th century.It was known that some viruses could transmit their genetic material into hosts and only contained DNA and a protein coat.Alfred Hershey and Martha Chase performed several tests in 1952 to demonstrate that DNA was the genetic material.In order to radioactively label a particular viral component, viruses (T2 bacteriophage) were cultured in one of two isotopic media.Viral proteins that had been radiolabeled during growth in radioactive sulfur (35S) (sulfur is present in proteins but not DNA)Radiolabeled DNA was found in viruses growing in radioactive phosphorus (32P) (phosphorus is present in DNA but not proteins)After the viruses had a chance to infect the bacteria (E. coli), they were centrifuged to separate the bacteria from the virus.While the tiny viruses stayed in the supernatant, the larger bacteria formed a solid pellet.The 32P-viruses (DNA) were found to make the bacterial pellet radioactive, but not the 35S-viruses (protein)Because DNA was transferred to the bacteria, it was proven that DNA, not protein, was the genetic material.learn more about Hershey and Chase experiment here: https://brainly.com/question/14452453

The CRISPR system targets DNA sequences for precisely cutting DNA and then letting natural DNA repair processes take over.
What is the CRISPR system?
CRISPR/Cas9 edits genes by accurately slicing DNA, which is then repaired by the body's mechanisms. The Cas9 enzyme and a guide RNA make up the system's two components. CRISPR stands for Clustered Regularly Interspaced Short Palindromic Repeats, which some bacterial species use as a component of their antiviral defenses. Co-founder Dr. Emmanuelle Charpentier and a team of researchers figured out how to employ this technology as a gene-editing tool (Jinek, et al. Science 2012) An enzyme known as a CRISPR-associated (Cas) endonuclease that functions as a "molecular scissors" to cut DNA where a guide specifies RNA. Deoxyribonucleic acid (DNA) is the genetic informational molecule that most organisms use to store the "instructions for life". Living beings employ ribonucleic acid (RNA), a molecule related to DNA, for a variety of tasks, including carrying and reading the DNA "instructions." RNA molecules known as "guide RNA" (gRNA) attach to Cas9.

The action potential spreads through an axon by depolarizing adjacent membrane to threshold.
K+ departs the cell after Na+, which enters the cell first. Ions can move freely across the axon membrane because of the difference during the action potential.Because sodium contains a positive charge, the neuron becomes more positive and depolarized. Potassium channels take longer to open. As soon as the cell does open, K+ rushes out, reversing the depolarization known as repolarization.Sodium channels close during the peak of the action potential when potassium leaves the cell. When potassium ions are effluxed, the membrane potential is lowered or the cell becomes hyperpolarized.Outside of the cell, the concentration of Na+ is greater than inside the cell. while the concentration of K+ is is greater inside the cell than outside.learn more about action potential here: brainly.com/question/6705448

Diagnostic reagents useful for detecting antigen by the COAGGLUTINATION reaction may be prepared by binding antibody to killed staphylococcal cells via the Fc receptor of staphylococcal protein A. The class of antibody bound by this protein is IgG.
IgG antibodies are monomers and do not agglutinate immediately (termed non-agglutinating antibodies).IgG antibodies are powerful molecules that have the special capacity to connect foreign particles to innate immune cells. IgG antibodies attach to cellular Fc receptors with a low affinity while recognizing antigens with a high affinity. Immune complexes are formed during these encounters, producing high-avidity interactions.

Visual and hearing receptors are irreplaceable, but the taste and olfactory receptors are continuously renewed True False
The statement "although taste and olfactory receptors are constantly renewed, visual and auditory or hearing receptors are irreplaceable." is true.
Visual Receptors: Rods and cones are the two types of cells present in the retina of the eye. They work as visual receptors which establishes a synaptic network involving neurons which connects the receptors to brain and help us in visualizing. However loss of neurons in the retina because of any kind of physical or biological damage permanently cuts the connection of receptors with brain and it cannot be replaced naturally.
Hearing receptors: Inside the ears there is a small structure known as cochlea which contains the Organ of Corti which further contains the hair cells [sensory cells] working as hearing receptors but research till date concludes that mammalian cochlear hair cells do not regenerate, either spontaneously or after damage.
Taste receptors: The small little bumps present of our tongue are known as papillae which functions as taste receptors as they contain taste buds. Scientifically there taste buds die off and regenerate every few weeks.
Olfactory receptors: These receptors keep on replacing due to continuous differentiation of basal cells which develop and are capable of reestablishing the connection with Central nervous system.
