Recessive allele means one is present... A hybrid is the result of two different breeds breeding. A purebred is an organism that always passes down the same genetic makeup.
name two characteristics that all these animal share ( frog, buck, doves, lizard, dragonflies )
Answer:
They all have a beating heart, and a brain
Explanation:
Beating the heart and a brain is the two characteristics that all these animal shares frog, buck, doves, lizard, and dragonflies.
What are the different characteristics of animals?Frogs are cold-blooded animals and are classified into the class of amphibians, they are vertebrate animals with backbones.
The lizard was included in the class reptilia, they are creeping and burrowing terrestrial animals situated on the land, and also have scales on their body. Similar to the frog, they are also cold-blooded animals having a backbone.
The major classification of the animals is done by the presence of a backbone, which differentiates them in vertebrates and invertebrates.
Therefore, in the given question all the animals share common feature of having a heart and brain.

The phase of mitosis that is characterized by the disappearance of the nuclear membrane is
Answer:
Prometaphase (late prophase)
Explanation:
Mitosis is the kind of cell division in which two genetically identical copies of a cell is formed from a cell. Mitosis comprises of stages which include prophase, metaphase, anaphase and telophase. Each phase is characterized by specific occurrences that all work together to achieve the main goal of forming two daughter cells.
According to this question, PROPHASE stage is the stage characterized by the condensation of chromatids into chromosomes, the disappearance of nucleolus and BREAKDOWN of NUCLEAR MEMBRANE.

Introspection is one of the many sleeping disorders experienced
by people with sleep apnea.
Select one:
True
False
Answer:
The statement is false.
Explanation:
Sleep apnea is a respiratory disease characterized by the fact that people who suffer from it habitually snore, have repeated stops of breathing (apneas) and drowsiness during the day. As a consequence, patients who suffer from it cannot rest well during the hours of sleep.The obstruction of breathing causes a decrease in oxygen levels in the body, the persistence of this lack of oxygen could cause pulmonary hypertension and a future right-sided heart failure or myocarditis. Introspection, on the other hand, is the immediate reflective capacity of the human mind to know its own states; it is not associated with sleep apnea.

C.

D.
It can detect objects behind the moon.

Explanation:
The main reason we put telescopes into space is to get around the Earth's atmosphere so that we can get a clearer view of the planets, stars, and galaxies that we are studying. Our atmosphere acts like a protective blanket letting only some light through while blocking others.
A scientist runs an SDS-PAGE experiment two separate times on a protein with a molecular weight of 200 kD. For the first experiment he treats the protein with SDS only and for the second experiment he treats the protein with both SDS and a reducing agent. If the first gel yields one band showing a molecular weight of 200 kD and the second run yields one band showing a molecular weight of 25 kD, the researcher should conclude that
Answer:
This protein consists of 8 subunits of equal size linked by disulfide bonds
Explanation:
The sodium dodecyl sulfate-polyacrylamide gel (SDS-PAGE) is a technique widely used in molecular biology laboratories to separate proteins with molecular weights between 5 and 250 kDa. SDS is an anionic detergent used to denature proteins before electrophoresis. SDS can denature proteins by altering non-covalent bonds such as hydrogen, hydrophobic and ionic interactions, but they cannot cleave disulfide bonds. In this case, reducing agents (e.g., β-mercaptoethanol or dithiothreitol) have been used to cleave disulfide bonds.
