1. Write a statement that uses (correctly) the terms gamete, fertilization, and zygote. (2)
Answer:
The zygote simply is the fertilized ovum or egg cell or female reproductive cell. It is the result of the process of fertilization of the fusion of the male reproductive cell (gamete) and the female reproductive cell ( gamete). In human, the zygote is the resulted cell of fertilization of the sperm and the ovum. It is diploid or 2N which means it contains two sets of chromosomes; one set from the male and the other from the female.
The gamete is the reproductive cell. There are two types of gametes; male gamete and female gamete. In human, the male gamete is called the sperm and the female gamete is called the ovum. The gamete is the last stage of the reproductive cells to be completely formed.
Fertilization is the fusion of the male gamete and the female gamete to form the zygote. Fertilization may be external as in fish or internal as in human.
please help fast. How do both systematics and taxonomy relate to phylogeny?
Answer: “ Systematics is concerned both with Taxonomy, the naming and classification of life, and Phylogeny, the science and study of understanding the family tree of all life on Earth. ... Systematics, then is the classification of life according to its phylogenetic (evolutionary) relationships.” -http://palaeos.com/systematics/
Systematic is related to the study of the evolution of a species over time and the relationship between them. Taxonomy is the naming and classification of animals and plants. The phylogeny is the study of family trees of every species on Earth, Hence they all are related to each other.
What is taxonomy?Taxonomy includes the study of naming and classifying animals and plants. By seeing the characteristic of a new organism, it is classified and put into kingdoms and groups.
Phylogeny and systematic are related to the evolutionary relationship between them, the family tree, and how an organism evolved over time.
Thus, Systematic has to do with the investigation of how a species changes over time and how they interact. The naming and categorization of plants and animals are known as taxonomy. Phylogeny is the study of family trees. These terms are related to each other.

Describe the environmental conditions that extremophiles are able to live in. Describe the environmental conditions that extremophiles are able to live in. Extremophiles were microbes that could only live in conditions that prevailed early in Earth's history when environments had high temperatures and pressure and lacked oxygen. Extremophiles includes those microbes that thrive in very high-salt, high-temperatures, low-temperature, high-pressure, low-pH, or high-pH harsh conditions. Extremophiles can only survive in habitats where there are extreme changes in close proximity, such as hydrothermal vents at the bottom of the ocean, where water as hot as 300°C emerges and mixes with 4°C seawater. Extremophiles are able to tolerate extreme conditions found in space such as a near vacuum and temperatures in excess of 300°C or several hundred degrees below 0°C.
Answer:
Extremophiles includes those microbes that thrive in very high-salt, high-temperatures, low-temperature, high-pressure, low-pH, or high-pH harsh conditions.
Explanation:
Extremophilic organisms are life forms that can grow in extreme environmental conditions, such as the above mentioned. In general, extremophiles are prokaryotic organisms (i.e., archaea and bacteria), although there are some eukaryotic species that are considered extremophilic organisms. Extremophiles are classified into two main types: 1-microorganisms that live in extreme conditions and 2-microorganisms that have the ability to tolerate extreme environmental conditions. Extremophiles are extremely important both in basic and applied research. An example of this is the thermostable Taq DNA polymerase obtained from the bacterium Thermus aquaticus (an extremophile that lives in areas of high temperature and pressure), which is essential to carry out the Polymerase Chain Reaction (PCR).

Most of the ocean floor is a type of rock called basalt. At the edge of continents, this basalt erodes and becomes small particles. Over time, the particles are compressed and form what type of rock? A. Igneous B. Basinic C. Metamorphic D. Sedimentary
Answer: D. Sedimentary
Explanation:
Sedimentary rocks are formed overtime are different particles of sand, shells, pebbles and other fragments of materials form layers and harden into rock.
The particles are compressed and form sedimentary rocks in the ocean floor. Ocean floor is the bottom of the waterbody. Thus, the correct option is D.
What is Ocean Floor?The seabed or ocean floor is the bottom of the ocean. All the floors of the ocean are known as 'seabed'. The structure of the ocean floor of the global ocean is governed by the plate tectonics.
Most of the parts of the ocean are deep, whereas the ocean floor is known as the abyssal plain. The seabed also known as the seafloor, ocean floor, and ocean bottom is the bottom of the ocean.
The ocean floor can be divided into three distinct regions which are the continental margins, abyssal plains, and the mid-ocean ridges. The ocean floor has rocks which are called basalt. Here, the basalt particles are compressed which forms the sedimentary rocks. Sedimentary rocks are formed by accumulation of minerals.
Therefore, the correct option is D.

w, use what you have learned about heredity to complete the chart below. The allele pairs in the left column represent eye color in fruit flies. Ris the
ominant color (red), and r is the recessive color (white). Study the chart and fill in the missing phenotypes.
Answer:
RR is hom0zygous dominant and will Red
Rr is heterosygous and will also be red
rr is hom0zygous recessive and will be white
Explanation:
The filling of the chart with respect to the genotype given is as follows:
RR (homozygous dominant) gives Red eye color in fruit flies. Rr (heterozygous) will also deliver red eye color in fruit flies.rr (homozygous recessive) gives white eye color in fruit flies. What is meant by Genotype?Genotype may be defined as the ultimate combination of alleles of those genes which are selected for specific study in order to deliver some sort of genetic information.
As it is an organism is its complete set of genetic material. These can also be utilized in order to refer to the alleles or variants an individual carries in a particular gene or genetic location.
In fruit flies, red eye color is dominant over white eye color. So, when red eyed-colored (RR) flies are crossed with white-eyed colored flies (rr), they produce offspring with the genotype Rr and phenotype of red-eye color. This all deals with the law of dominance.
Therefore, the filling of the chart with respect to the genotype given is well described above.

The gene for a long neck also gives stronger, faster muscles, which gives tortoises with this trait
an advantage in catching insects. How would this advantage affect the population of tortoises from
Generation 1? How may that affect subsequent generations?
Answer:
it would help them thrive
Explanation:
because it anables them to catch more with there stronger faster necks
The shift in the traits of tortoises in the population states how natural selection drove the evolution of the tortoises.
Why do tortoises shift in their traits?During the evolution, with an extended period of time, the shorter vegetation became less available and tortoises with short necks had the disadvantage to survive in that area.
Tortoise develops genes for a long neck and having stronger, faster muscles, which gives tortoises with this trait an advantage in catching insects.
This natural selection helps the tortoises, to survive by catching more food in a particular area, it states tortoises with long necks are the only tortoises living during evolution.

Diabetes is a disease characterized by the inability to break down sugars. Often a person with diabetes has a defective DNA sequence that messes up the code for making insulin. Suppose a person has a mutation in their DNA, and the first triplet for the gene encoding insulin is CCC (instead of CCA). Determine what amino acid the new DNA triplet codes
Answer:
The new CCC codon codes for proline, while the original CCA codon also encodes for proline
Explanation:
A synonymous substitution is a mutation produced by the substitution of one nucleotide for another in an exonic gene segment which doesn't modify the original amino acid in the protein sequence. Moreover, a silent mutation is any alteration in the nucleotide sequence that does not produce an observable effect on the organism's phenotype. The example above describes a synonymous substitution because the new codon (CCC) also codes for the same proline amino acid as the original non-mutated codon, thereby the resulting protein sequence remains unchanged. Consequently, in this case, mutations associated with diabetes are located at other gene regions. The genetic code is degenerate because different codons can code for the same amino acid.
