What process facilitates locomotion for the ovum?

Question 6 options:

a. Once the ovum leaves the ruptured follicle it is captured by the uterus and then directed into the Fallopian tube, where it is pushed along towards the oviducts.


b. Once the ovum leaves the ruptured follicle it is captured by the fimbriae and then directed into the Fallopian tube, where it is pushed along towards the uterus via cilia.


c. Once the ovum leaves the ruptured follicle it is fully matured and propels itself into the Fallopian tube, where it moves along towards the uterus.


d. Once the ovum leaves the ruptured follicle it is captured by the cervix and then directed into the Fallopian tube, where it is pushed along towards the uterus via cilia.

Answer:

Chemical energy from food molecules (potential energy) may also be transformed to mechanical energy (kinetic energy) when the body moves. In every energy transformation, some energy is given off as heat. This is why the body warms up during different activities like exercising, lifting weights, and even digestion!

Answer: The program completed in a quarter of the time with four computers versus one computer

Explanation:

Distributed computing simply means using distributed systems in solving computational problems and this is done as the problem is divided into many tasks, whereby the tasks are accomplished by one or more computers.

Following the information given in the question, a speedup of 4 indicate that the program completed in a quarter of the time with four computers versus one computer.

Answer:

In the founding population, the allele frequency is different from the original bigger-sized population. The size of the new population affects this difference even more. Some of the alleles will tend to increase, while some others will tend to decrease in frequency.

Explanation:

Genetic drift is an evolutive force. It is the random change that occurs in the allelic frequency of a population through generations. Its effects are harder in a small-sized population, meaning that the magnitude of this change is inversely related to the size of the original population.  

Genetic drift results in some alleles loss -including the beneficial ones-, while some other alleles get fixated. Low-frequency alleles are the most likely to be lost. The changes produced by genetic drift accumulate in time and results in a loss of genetic variability within a population.  

Genetic drift affects a population and reduces its size dramatically due to a disaster or pressure -bottleneck effect- or because of a population split -founder effect-. The bottleneck effect most likely affects smaller populations.  

Founder effect refers to the origin of a new population from only a few individuals that are coming from a bigger-sized population. These founder individuals, which are carrying some of the genes of the original population, settle down in a new area and reproduce. The new and small population might or might not be genetically representative of the original one. Some rare alleles might be exceeded or might be lost by complete. Consequently, when the small population increases in size, it will have a genetically different composition from the original one. In these situations, genetic variability is reduced, and there exists the possibility of developing a peculiar allelic composition. When the number of individuals that originated the new population is low, the founder effect will be very extreme because the genetic drift effects are inversely proportional to the original number of individuals.

isotonic

Explanation:

In hypotonic environments, the cells fill with water and bloat until they explode.

In hypertonic environments, the cells will lose their water and shrink.

In an isotonic environment, the cells would remain constant and thrive.

Answer:

Logistic Growth Model

Explanation:

The logistic model is realistic because it suggests the fact that the population of species is regulated and controlled by the carrying capacity (maximum members that an ecosystem supports) of the ecosystem. The population becomes small when the carrying capacity decreases.

Answer:

I've grown potatoes on top of loose earth that's covered by a thick layer of loose straw. It allows the green leafy parts to easily push through to the sunlight above while keeping developing tubers protected from light. I've grown them this way because I really enjoy the taste of fresh new potatoes and have no desire to store mature potatoes for winter. I want to get the most baby potatoes possible while not damaging the plants with tiny potatoes not big enough to eat yet. It also keeps the potatoes cleaner than if grown under the soil.

When I start lifting the straw back to pick the largest new potatoes, I can see the development of the other potatoes. While the biggest potatoes are 1 1/2 to 2 inches in size, others range in size all the way down to 1/4 inch or less.

When a specific garden plant blooms, most of the flowers open within a very short time period. Now think of tomato plants. The flowers continue to open over a period of months and both ripe tomatoes, large and small green tomatoes as well as flowers can all be found on the same plant. Not all the fruit will be ripe before cold weather kills the plant.

Potatoes are closely related to tomatoes and like tomatoes, not all the tubers will be full size when the plant dies back. So I'd say it's neither genetics nor environmental factors but the inherent life and growth cycle of potatoes that account for the tuber size difference.

The difference in the tuber size in plants of potatoes and tomatoes does not depend upon its genetics or environmental factors rather it depends upon the inherent life and growth cycle of the plant.

Growth cycles are the recurrent fluctuations in the series of deviations from the usual trend of the plant growth. Thus, the growth cycle contractions in the plant include slowdowns as well as absolute declines in the activity, whereas business cycles contractions include only the absolute declines or recessions.

Potatoes are the plant species which are closely related to tomatoes and just like tomatoes, not all the tubers will be full size when the plant dies back in time. So, it is neither the genetics nor the environmental factors but the inherent life and growth cycle of the potato plants that account for the tuber size difference in the plants which are genetically identical to each other.

Answer:

Amino acid generated from tyrosines and tryptophan (end in '-ine') and includes adrenaline and norepinephrine. The (produced by the adrenal medulla). Thyroxine (production from the thyroid gland) and melatonin are also included in the amino acid hormones (produced by the pineal gland).

Explanation:

The main control over hormone production and release is negative feedback. The stimulation causes the release of a chemical in negative feedback systems; once it reaches a specific level, the substance sends a signal stopping further discharge.

This ensures a narrow range of the levels of hormones in the blood.

For example, blood glucose is controlled via negative feedback to secrete insulin and glucagons.

uracil

Explanation:

uracil is complenentary to adenine in transcription

The diagram below shows part of the process of DNA transcription. Uracil mRNA base will go in location 1.

The process of turning a piece of DNA into RNA is called transcription. Messenger RNA is said to be produced when DNA segments are transcribed into RNA molecules that can encode proteins.

DNA record is the cycle by which the hereditary data held inside DNA is re-composed into courier RNA (mRNA) by RNA polymerase. After that, this mRNA leaves the nucleus and serves as the foundation for DNA translation.

The nucleus is where transcription takes place. An RNA (mRNA) molecule is produced by using DNA as a template. During record, a strand of mRNA is made that is corresponding to a strand of DNA.

Answer: C. 10% of the energy Primary consumers absorb is lost as heat.

Explanation:

According to the ten percent law of energy flow only 10 percent energy is transferred from one trophic level to the next trophic level and rest of the energy is used to develop the biomass and lost as heat. As the loss of heat is an essential exothermic reaction after the digestion and assimilation of food the energy is lost as heat from the body of the primary consumers is 10%. Primary consumers are animals that are dependent on plants for their food requirements for example deer, goat and others.
