Circadian rhythms in constant environments are said to be ________________, and their duration is called the _________________.
mars1129 [50]

Circadian rhythms in stable contexts are referred to as diurnal rhythms, and the free-running period refers to their duration.

The rhythm lasts for roughly 24 hours under continuous circumstances, i.e., perpetual darkness. The Greek letter is used to represent the free-running period, which is the rhythm's time under constant conditions (tau). This criterion's justification is to separate circadian cycles from straightforward reactions to daily environmental inputs.

What exactly is a circadian rhythm?

A circadian rhythm, also known as a circadian cycle, is an internal, naturally occurring process that controls the sleep-wake cycle and occurs roughly every 24 hours. It can refer to any process that is endogenous, or occurring inside an organism, and reacts to its surroundings (entrained by the environment). This 24-hour cycle is driven by a circadian clock, and they have been found in a variety of organisms, including cyanobacteria, fungi, and mammals.

The words circadian, which mean "around," and dies, which mean "day," are Latin words. Diurnal rhythms are more commonly used to describe 24-hour cycles; they should not be referred to as circadian rhythms until endogenous, not environmental, origins can be established.

Despite being endogenous, circadian rhythms are adapted to the local environment by outside factors known as zeitgebers, which include light, temperature, and redox cycles. A circadian rhythm sleep disorder is the term used in clinical settings to describe a disturbed circadian rhythm in humans.

cupoosta [38]

Answer:

A. The man's genotype is Bb. Phenotypes of the offsprings:- heterozygous brown-eyed- homozygous blue eyedGenotypes of the offsprings:- Bb- bbb. The blue is recessive, so the woman's genotype is bb. It is impossible for her to have B because it is dominant over b.c. The woman can only produce bb or blue-eyed.d. The man's genotype is Bb. It is impossible for him to produce an offspring with blue-eyes if his genotype is BB.e. The man can produce Bb or brown-eyed and bb or blue-eyed.

Which best describes reproduction? Asexual reproduction produces offspring that are identical to the parent. Sexual reproduction
Juliette [100K]

The right answer is Asexual reproduction produces offspring that are identical to the parent.

Sexual reproduction is ensured by fertilization, that is to say by fusion of male and female gametes giving an egg (or zygote). This reproduction allows the maintenance of a genetic diversity within the populations, because it ensures the genetic mixing.

Asexual reproduction (sometimes vegetative propagation) refers to all other means of multiplication in which neither gamete nor fertilization occurs. In this case, the sex of the parents and the descendants remains identical, because only the mitosis ensures the transmission of the genetic information to the new cells. It is a form of natural cloning.
