The sex of an organism is typically determined genetically, but environmental factors can also play a role. Scientists examined the roles of genes and environmental temperature in the sex determination of a lizard species. Individuals with a ZWpair of chromosomes are always female (ZWf), while individuals with a ZZ pair of chromosomes can be either male (ZZm) or female (ZZf). Scientists mated ZWf or ZZf females with ZZm males and incubated the eggs produced in 20 clutches at temperatures ranging from 23°C to 36°C. When the young hatched, the scientists determined their sexes (Table 1). Among the eggs that did not hatch, the mortality of embryonic lizards was approximately the same for both males and females.
(b) Using the template, construct an appropriately labeled graph, including error bars, to represent the data in Table 1. Based on the data, compare the ZZm×ZWf crosses and the ZZm×ZZf crosses to determine whether there is a significant difference between the two crosses in the fraction of female progeny produced at 24°C, 32°C, and 36°C.

What is the application of biology to biotechnology?Biotechnology is defined as the use of biology to solve problems and make useful products with the help of microbes. The most prominent approach is genetic engineering which enables scientists to alter and modify an organism's DNA. Microbiology has proved to be one of the most significant fields in biology, making it possible to define microorganisms that cause diseases, discover treatments for different diseases, and use microbes for industrial applications, etc.
Each human body hosts about ten microorganisms for every human cell, and these microbes help in digestion, produce vitamin K, enhance the development of the immune system, and remove harmful chemicals. Microbes are essential to making many foods such as bread, cheese, wine etc.
So we can conclude that the application of biology especially the role of microbiology and biotechnology leads to the welfare of humans.

Answer:
Produce sperm and egg cells (option d)Make identical types of cells (option b)Cancer (Option c)Interphase (option b)10% (option a)46 chromosomes (option b)Prophase (option a)Metaphase (option b)Anaphase (option c)Spindle fibers (option b)Telophase (option d)Cytokinesis (option b)Explanation:
There are two principal types of cells in the organism: Somatic diploid cells (2n) that reproduce by the process of mitosis, and germ cells that are diploid reproductive cells in charge of gamete production. Germ cells divide by mitosis and meiosis. Through the process of mitosis, they originate more sexual cells, but through the process of meiosis, they give place to haploid gametes, called sperm and egg cells, through the gametogenesis process.
Both somatic cells and germinal cells will end their cycle becoming two daughter cells with the same genetic dotation. Mitosis produces two daughter diploid cells (2n) from a diploid somatic cell (2n). During mitosis, the whole cell (23 chromosomes) first duplicates producing 46 chromosomes. Then the duplicated cell separates, producing two equal cells carrying 23 chromosomes each.
When we talk about the cell cycle, we refer to the interphase and the cell division (mitosis or meiosis).
The interphase occurs before mitosis and involves 90% of the cell cycle. The interphase is conformed of the G1, S, and G2 stages.
• During the G1 stage, it occurs a high intense biochemical activity. The cell duplicates its size, and the organelles and other molecules and cytoplasmatic structures also double. Some structures, such as microtubules and actin filaments, are synthesized from zero. The endoplasmic reticulum increases in size and produces a membrane for the Golgi complex and vacuoles, lysosomes, and vesicles. During this stage, the pair of centrioles separate, and each centriole duplicates. Mitochondria and chloroplasts also replicate.
• During the S stage, the DNI replication process occurs. This is the only stage in which the DNI molecule replicates. The synthesis of histones and other associated proteins also occurs.
• G2 stage is the interphase last step. DNI molecule begins to slowly condensate. The centrioles duplication process completes. The spindle fibers get assembled.
Once the whole interphase is completed, mitosis occurs involving 10% of the cell cycle.
During mitosis, the original cell with duplicated material suffers division, originating two exact same daughter cells. Mitosis occurs in only one phase.
In the prophase, it occurs chromosomes condensation and nuclear membrane breaks. During the metaphase, fibers of the spindle drive chromosomes and take them to the cell equatorial plane, where they line up. Each chromatid joins with a microtubule of opposites poles, but sister chromatids are still together.In the Anaphase, enzymes are activated to break the bonds and separate the chromatids, which migrate to the opposite poles, helped by the single apparatus fibers.In telophase, the duplicated chromosomes are already in the corresponding poles, and the nuclear membrane forms again in each pole.Finally, occurs cytokinesis, which involves the invagination of the cell membrane and cytoplasmic division.Next week produces a heat wave in Prince George's County. Most scientists would say:
A. Global warming is the cause
B. Human activity is the cause
C. Local temperatures over one week tell us more about weather than climate
D. Our climate is getting warmer
Answer:
A. Global warming is the cause
Explanation:
Our climate is getting warmer due to production of heat wave because the heat wave has high temperature which increases the temperature of the surrounding environment. Researchers found that as global temperatures increase, heat waves will become more frequent and the time between them will become shorter and we know that global temperature increase due to global warming so we can say that global warming is the cause of more heat wave.

Describe 2 processes that are a part of the carbon cycle . Additionally why is it important to study and understand the carbon cycle
Through the cycle of photosynthesis, carbon dioxide is pulled from the air to deliver food produced using carbon for plant development. Carbon moves from plants to creatures. Through natural ways of life, the carbon that is in plants moves to the creatures that eat them. Creatures that eat different creatures get the carbon from their food as well.

DNA sequencing by the chain-termination method utilizes DNA polymerase I to make a complementary copy of the target or template DNA molecule. A reaction with a 20 bp template and dideoxyadenosine nucleotides as terminators results in the production of a 5 bp fragment. Based on this result, we can conclude that the template contains A) a cytosine at position 5. B) a thymine at position 5. C) a cytosine at position 16. D) a thymine at position 16
Answer:
D) a thymine at position 16
Explanation:
The chain termination method (Sanger sequencing), is a sequencing technique used to determine the nucleotide sequence of a specific fragment of DNA. The classical method has three steps: 1- the target DNA fragment to be sequenced is used as a template for chain-termination PCR technique where modified deoxyribonucleotides (ddNTPs) are added to the PCR reactions to be incorporated by the DNA polymerase during in vitro DNA replication, 2-the DNA fragments of different sizes are separated by electrophoresis, and 3-determination of the DNA sequence by observing the identity of the terminal ddNTP in each band of the electrophoresis gel. For example, if the bottom band in the electrophoresis gel colocalizes in the column with ddATP as terminator, then this fragment finishes with ddATP, which means that the last nucleotide from the 5' end is Adenine.
Why are humans able to live in a variety of places on Earth?
Answer:
Early humans used to move from place to place to those days. Reason are given below.
Explanation:
200,000 years ago from the present, modern humans have already started to roam around the planet. They learned everything around them. They risked their lives to become more modern. They invented weapons, tools, hunting, agriculture, communication methodologies and more in order to survive.
During the early ages, humans are the most sensitive species on the planet. They have just evolved to be a six sensed animal and have no idea about the planet. However they have learned to survive on the planet by hunting other animals and eating them. Their life cycle seemed to be stuck with some sort of danger all time. So they wanted to move from place to place in order to survive.
When they started to move across continents, geographical location and climate have influenced their behavior and life style. Humans have started to multiply within some suitable geographical locations. They started to improve their life style by adapting the location.
