No, two haploid offspring produced by parthenogenesis would not be genetically identical

because the cells that the organisms grow from would be the products of meiosis and therefore the chromosomes in each cell would be random and unlikely to be the same.

Parthenogenesis is a kind of reproduction from an ovum without fertilization, especially as a normal process in some invertebrates and lower plants, but also occurs in fish, reptiles, and amphibians.

Parthenogenesis  is useful Because it  allows female animals to reproduce when no males are available to reproduce with and it is not useful too because it decreases genetic diversity

There is no six-legged starfish in existence. Fixation may be to blame. Fixation is a condition in which there is only one allele in the population and the other allele is extinct.

Given that in total 26 starfish are normal and 1 has 6 legs.
Genotypic frequency of 6 legs is 1/27 =0.037.
Genotypic frequency is always 1 and is given by p2 + 2pq + q2 = 1.

Allelic frequency = p + q = 1
So, frequency of p = 1-0.19 = 0.81

After 2 years, the Chi-square value:

            Observed    Expected    O-E      (O-E)2         (O-E)2/E

5 leg: 0.81               0.6           0.16        0.0256        0.039385

6 leg: 0.19               0.35      -0.16        0.0256        0.073143

                                                                                              0.112527

So Chi-square value is 0.112527.

Genotypic frequency of 6 legs is 4/31 =0.129

        P = 1 - 0.35

        P = 0.65

So new allelic frequency for 6 legs is 0.35.

New allelic frequency for 5 legs is 0.65.

This random change of allelic frequency is called as genetic drift.

Question correction:

On your Spring Break in Mexico, you take a break to count the starfish in a tidal pool. You notice that there is a rare recessive trait that causes the starfish to have 6 legs instead of 5. Of the 27 starfish you can find, only 1 has 6 legs. What are the allele frequencies for this population? Two years later, you return to the same beach and count the starfish again. This time you find 4 starfish out of 31 that have 6 legs. Are the genotype frequencies the same as two years earlier? Test using Chi square. If it is not, calculate the new allele frequencies. Given that the current mutation rate is O and that there is no natural selection acting on these starfish, what is this random change in allele frequency called?)

Seven years later, you come back to the beach. This time you can find no starfish with 6 legs. Given the most recent allele frequencies you know, is this what you would expect? (What is the complete loss of a allele called?)

When the normal process is blocked in Jost's experiment then the normal way the embryos would develop as he removed the parts in all the embryos in his experiment that would develop that are from the gonads.

Male and female gonads are the most important regenerative organs. The testicles are the male balls, and the ovaries are the female genitals. These regenerative framework organs are liable for the advancement of male and female gametes, which are expected for sexual proliferation.

In Jost's experiment, the typical cycle impacted is the hormone creation by the embryo’s gonads during advancement. The job of these gonads in creating mammalian genitalia was that without a sign from the male balls, all embryos create as female, whether or not they are hereditarily male (XY) or female (XX).

The experiment suggests that without the signal from the male gonads, whether the embryo is male or female, they would develop as male.

The independent variable is the variable that changes.

An independent variable is one that you adjust, control, or modify in an experimental study to look at its consequences. Because it is unaffected by any other study variables, it is called "independent."

The independent variable in an experiment is the thing you modify, and the dependent variable is the thing that changes as a result of the independent variable.

This is an easy way to conceive of independent and dependent variables. The independent variable can alternatively be viewed as the cause, and the dependent variable as the result.

Predictor variables are another name for independent variables. This is so that changes in reaction can be "predicted" and explained using this variable. For instance, an independent variable like the amount of fertilizers can help us to know how much plant growth will occur.

The passage of energy from one place to another is known as energy transfer. When energy transforms, it goes from one type to another.

The greatest strategy to reduce energy consumption in challenging circumstances, such as when the outside temperature is at or below 0 °C, is to hibernate.

Animals are found to incur expenditures during hibernation. Both the negative physiological side-effects of hibernation and the costs associated with being unable to respond to stimuli are included in these expenses.

According to definition, hibernation is a state of torpor that is only experienced during the winter and is sustained for periods longer than 24 hours. A mammal's metabolism slows down during hibernation, allowing the body temperature to drop to a few degrees above ambient levels. The animal will actively produce heat when its body is too chilly to keep alive.

False. An increase in the capacity or affinity of the transport protein would reduce the amount of free hormone and its effect on the tissue.

Hormones that are attached to proteins are in an equilibrium state, whereas unbound hormones are concentrated less. Free hormones in serum leave the bloodstream to operate on tissues, whereas bound hormones separate from their binding protein.

Transport proteins defend against spikes in hormone output and aid in spreading hormones uniformly to all of the cells in large organs like the liver.

Hence, false is the correct answer because of the transport protein's attachment to other hormones, an increase in its capacity or affinities will result in a decrease in the amount of free hormone rather than an increase.

Membrane fusion is the membrane activity that occurs both in the fertilization of an egg and in neurotransmission across a synapse.

One of life's most essential processes, membrane fusion, happens when two distinct lipid membranes combine to form a single continuous bilayer. Fusion reactions have similar characteristics, but different proteins operate as their catalysts. In order to destabilize the lipid/water barrier and start the mixing of the lipids, these proteins facilitate the first identification of the membranes that are intended for fusion and bring the membranes close together.

To provide strict control in space and time, assemblies of protein complexes or a single fusion protein may be all that is needed for intracellular fusion processes. In order to effect the merging of the bilayers, cellular fusion machines are modified to suit the requirements of various reactions, but they function according to similar principles.
