What is the ten percent rule of ecology
Answer: law
Explanation:
10% law. When organisms are consumed, approximately 10% of the energy in the food is fixed into their flesh and is available for next trophic level (carnivores or omnivores). When a carnivore or an omnivore in turn consumes that animal, only about 10% of energy is fixed in its flesh for the higher level.

The difference in the chromosome arrangement during meiosis in the metaphase plate can lead to greater genetic diversity in a population. Explain your answer
Explanation:
Like mitosis, meiosis is a form of eukaryotic cell division. However, these two processes distribute genetic material among the resulting daughter cells in very different ways. Mitosis creates two identical daughter cells that each contain the same number of chromosomes as their parent cell. In contrast, meiosis gives rise to four unique daughter cells, each of which has half the number of chromosomes as the parent cell. Because meiosis creates cells that are destined to become gametes (or reproductive cells), this reduction in chromosome number is critical — without it, the union of two gametes during fertilization would result in offspring with twice the normal number of chromosomes!
Apart from this reduction in chromosome number, meiosis differs from mitosis in yet another way. Specifically, meiosis creates new combinations of genetic material in each of the four daughter cells. These new combinations result from the exchange of DNA between paired chromosomes. Such exchange means that the gametes produced through meiosis exhibit an amazing range of genetic variation.
Finally, unlike mitosis, meiosis involves two rounds of nuclear division, not just one. Despite this fact, many of the other events of meiosis are similar to those that occur in mitosis. For example, prior to undergoing meiosis, a cell goes through an interphase period in which it grows, replicates its chromosomes, and checks all of its systems to ensure that it is ready to divide. Like mitosis, meiosis also has distinct stages called prophase, metaphase, anaphase, and telophase. A key difference, however, is that during meiosis, each of these phases occurs twice — once during the first round of division, called meiosis I, and again during the second round of division, called meiosis II.

What is duplication event ?
Answer:
Duplications arise from an event termed unequal crossing-over that occurs during meiosis between misaligned homologous chromosomes. The chance of it happening is a function of the degree of sharing of repetitive elements between two chromosomes.

The Barton Springs salamander is an endangered species found only in a single spring in the city of Austin, Texas. There is growing concern that a chemical spill on a nearby freeway could pollute the spring and wipe out the species. To provide a source of salamanders to repopulate the spring in the event of such a catastrophe, a proposal has been made to establish a captive breeding population of the salamander in a local zoo. Suppose you are asked to provide a plan for establishing this captive breeding population, with the goal of maintaining as much of the genetic variation of the species as possible in the captive population.
What factors are likely to lead to a loss of genetic variation in the captive population?
a. increased rate of mutation
b. a founder effect
c. reduced genetic drift over time
d. a lack of inbreeding
What strategy would likely be effective in mitigating the loss of genetic variation in the captive population? a. keeping the sex ratio as close to 50:50 as possible
b. stopping gene flow to and from the captive population
c. regularly mating individuals that are related
d. keeping the captive population as small as possible
Answer:
1. b. a founder effect
2. a. keeping the sex ratio as close to 50:50 as possible
Explanation:
The founder effect is a phenomenon that occurs when a small subset of individuals split from a larger population in order to establish a new colony. The founder effect is known to cause a reduction in genetic variation of the colony due to genetic drift, i.e., due to the random sampling of the individuals that form the colony (which doesn't reflect the total genetic diversity of the original population). Moreover, the sex ratio refers to the proportion of males to females in a population. When establishing a captive population, it is recommended to maintain a sex ratio as close to 50:50 as possible because it reduces inbreeding, and thereby mitigating the loss of genetic variation. In some populations, it has been proposed that a 50:50 sex-ratio might also increase the competition between males, which is believed to be fundamental for maintaining a healthy genetic structure of the population.

Consider the following scenario:
An animal is born with a shorter tail. This makes no difference to its ability to survive or reproduce, but as a result of pure luck, the animal survives, reproduces, and passes its shorter tail down to its offspring. Over time, the species develops a shorter tail.
What type of process is described in this scenario?
Answer:
1. genetic drift
2. genetic modification.
3. The fish experienced an evolutionary change because of genetic drift.
4. A farmer intentionally breeds oranges to be more resistant to aphids.
5. evolution.
Explanation:
100% Evolution Versus Natural Selection Quick Check
Recessive alleles are the alleles that get masked and dominant are the traits that get expressed. The short tail of the animal is a recessive trait. Genetic drift is described in the scenario.
What is Genetic drift?The alteration of the frequency of the existing allele for a specific trait with another or the recessive due to random sampling is called genetic drift. The sample allele plays a role in the determination of the survival rate and the reproduction rate of the organisms.
Natural selection is the process of choosing the organism with the better trait qualities that can survive and reproduce in the altered environment, while artificial selection is the man-made selection.
Genetic modification is the manipulation of the genes or the genetic material of the organisms either naturally by mutation or through genetic engineering by humans. So, the adaptation of the short tail in the organism is not genetic modification.
Therefore, the process of genetic drift is explained in this scenario.

Explanation:
Pablo’s blood type is B+ while his mother’s blood type is O-. Which are the potential blood types of his father?
Answer:
the father may be BB++ BB +- BO ++ or BO +-
Explanation:
The blood type is a monogenic inherited trait that has three different alleles: A and B alleles are dominant, while the O allele is recessive. Each parent donates one ABO allele to their offspring. On the other hand, the Rh factor single gene inherited trait that has two alleles: the Rh-negative (-) factor is recessive to the Rh positive (+). Each parent donates one Rh factor allele to their offspring. In this case, the mother has the genotype OO -- (recessive for both genes), while Pablo has a phenotype of B+ and a genotype BO+- (i.e., Pablo is heterozygous for both genes). In consequence, the father may have the following genotypes: BB++ BB +- BO ++ or BO +-, from these combinations you could get a son with the genotype BO+- .

Two DNA molecules, containing the same
genetic code as the original DNA molecule, are
produced.
New DNA molecules are formed that have new
sequences of DNA nucleotides from the
original
Answer:
Two DNA molecules, containing the same genetic code as the original DNA molecule, are produced.
Explanation:
DNA replication is a very important process that must occur in every living cell prior to cellular division. It is the process by which a DNA molecule makes another copy of itself i.e. duplicates itself, to form two identical molecules of DNA.
In the process of DNA replication, the double-stranded molecule first unwinds to form two single strands of DNA. Each DNA strand serves as a template for making another complementary strand of DNA. At the end of replication, each copy of DNA molecule contains one new strand and one old strand. Both copies contain the same genetic code as the original DNA molecule.

Plant stems can be ______, ______, thick,______, or _________.
Answer:
Underground stem, Aerial stem, and subaerial stem.
Explanation:
Plant stems can be Underground stem, Aerial stem, and subaerial stem due to its presence and strength of the stem. Underground stem are thick stems that run below the ground surface. e.g rhizome. Aerial stems are thin stems that can not stand erect. Examples include watermelon and strawberry etc. Subaerial stems are very thin stems that do not rise up but grow just above the ground. for example, water plantain, flowering rush etc.
