Mr. Harris mows his lawn twice each month. He claims that it is better to leave the clippings on the ground. Which long term effect will this MOST likely have on his lawn?
Answer:
It will provide the lawn with needed nutrients
Explanation:
Robert and his wife are ready to start a family, but they are concerned about having a child an inherited disease. This disease is a recessive disorder which requires both parents to contribute a recessive allele in order for the child to express the disorder. If both Robert and his wife are heterozygous for this trait, what is the probability that one of their children will have the disease?
The probability is 1/4
Both parents are heterozygous.
Aa + Aa
This will give the following possibilities for offspring genotype:
AA, Aa, Aa, aa
As you can see the chance of a offspring having 2 copies of the recessive allele (which is required for the offspring to have the inherited disease is only a 1 in 4 chance.

how humidity affects the rate of transpiration?
Answer:
Relative humidity: As the relative humidity of the air surrounding the plant rises the transpiration rate falls. It is easier for water to evaporate into dryer air than into more saturated air. Wind and air movement: Increased movement of the air around a plant will result in a higher transpiration rate.

3. Synthesize in your own words, explain why scientists believe that threats to amphibians present a warning about a number of environmental threats to Earth's biodiversity Refer to the Case Study.
Explanation:
Scientists give three reasons. First, amphibians are sensitive biological indicators of changes in environmental conditions such as habitat loss, air and water pollution, ultraviolet (UV) radiation, and climate change.Amphibians are sensitive biological indicators of environmental circumstances such as habitat loss, pollution of the air and water, ultraviolet (UV) radiation, and temperature change.
What is biodiversity?The variety and variability of life on Earth is referred to as biodiversity or biological diversity. A measure of variation at the genetic, species, and ecosystem levels is called biodiversity.
Biodiversity refers to the variety of all the diverse species of organisms that dwell on our planet, including the plants, animals, insects, and microorganisms.
Each of these things exists in a delicate balance and coexists with the others in ecosystems that nourish and sustain life on earth.
Amphibians are sensitive biological markers of changes in environmental conditions like temperature, UV radiation, habitat loss, and air and water pollution.
Thus, scientists believe that threats to amphibians present a warning about a number of environmental threats to Earth's biodiversity.

Mutated codons code for what in silent mutations?
Answer:
Code for the same amino acid as the original codon
Explanation:
Mutation, which is any alteration in the nucleotide sequence of a gene, can occur when there is a replacement of base nucleotides. This is called SUBSTITUTION MUTATION. Substitution mutation can either lead to missense, nonsense or silent mutations.
As stated in this question, SILENT mutation is the one in which there is no change in the amino acid sequence after translation of the mutated mRNA. In other words, the mutation leads to an alteration of codon but the MUTATED CODONS CODE FOR THE SAME AMINO ACID as the original codon, hence, no effect on the protein produced or individual, in general.

Answer:
Typically, the nucleus of a cancer cell is larger and darker than that of a normal cell and its size can vary greatly. Another feature of the nucleus of a cancer cell is that after being stained with certain dyes, it looks darker when seen under a microscope
Explanation:
In contrast to normal cells, cancer cells don't stop growing and dividing, this uncontrolled cell growth results in the formation of a tumor. Cancer cells have more genetic changes compared to normal cells, however not all changes cause cancer, they may be a result of it.

It is mistakenly believed that the rapid evolutionary changes of punctuated equilibrium are the result of some mechanism of evolution other than natural selection, thus seeming to undermine evolutionary theory. This belief is mistaken because:
Answer: Natural selection can be defined as the differential survival and reproduction of members of the population of a species that have suitable traits to survive in a population of species.
Explanation:
The punctuated changes in the population of species have been found inordinately faster in the geological time scale, but changes per-generation have been relatively slow. Also, the rate of evolution in such a population is also slow. The punctuated changes in the population are because of evolution but the per-generation changes are the outcomes of the natural selection, in which only the beneficial traits are passed from one generation to another.

What happens to the cells of a person who has cancer?
Explanation:
Cancer happens when cells that are not normal grow and spread very fast. Normal body cells grow and divide and know to stop growing. Over time, they also die. Unlike these normal cells, cancer cells just continue to grow and divide out of control and don't die when they're supposed to.

When tulips bloom, they are attempting to pollinate using the process of meiosis which part of tulip is related to meiosis? Why do tulips need to under go meiosis?
Answer:
The correct answer is - pistil and stamen.
Explanation:
Meiosis is the type of cell division that takes place only to produce gametes that are megaspore and microspore, in sex cells of the flowering plant. In tulip and other similar flowering plants have ovary at the base of the pistil that contains and produced megaspore (female spores) by meiosis.
Similarly, anthers in the stamen of the tulip flower produce male spores called microspores and contain. Meiosis is essential in sexual reproduction to ensure that each cell has the correct number of chromosomes and responsible for recombination.
During pollination Tulip under meiosis in other to produce the required gametes needed for sexual reproduction. The parts of the Tulip that contains the megaspore and microspore gametes are :
Pistil : The ovary that produces and stores the female spores via meiosis is located at the base Stamen : The anthers which produces the male spores via meiosis is located at the stamen.Also Tulips undergo meiosis to ensure that the cells have the accurate number of chromosomes that is to be used for recombination.
