Answer:
Copying the book would be analogous to transcription
Explanation:
The copies made from the copying process would be analogous to mRNA. Taking the copy to a workbench would be analogous to the mRNA moving from the nucleolus to the ribosomes in the cytoplasm. The actual building of the dog house would be analogous to the ribosome assembling up the protein using amino acids. Following the instructions of the copy would be analogous to the ribosome reading the codons and bringing in the respective amino acids.
My boss isn't willing to increase the number of vacation days we get each year. that means she doesn't care about our health. it's wrong not to care about employees' health. she should be replaced with someone who cares about employees' health."
Talk to someone higher than her in status in the job?
Final answer:
Decisions about vacation policies involve various factors; it is not solely a measure of how much employers care about employee health. Supporting employees in work-life balance and understanding the implications of workplace health is becoming increasingly important in modern businesses. Engagement and support from supervisors are crucial in encouraging employees to take their allotted time off.
Explanation:
The assertion that a boss who is not willing to increase the number of vacation days does not care about employee health may not be entirely accurate. There are various factors influencing decisions around employee benefits beyond just caring for employee well-being. However, it is true that there is a growing understanding in the business community about the importance of employee health and work-life balance.
In 2015, according to Project Time-Off, 55% of U.S. workers did not use all of their paid vacation time and as a result, a staggering 658 million vacation days were lost. Businesses are beginning to recognize that unhealthy habits like smoking or being overweight increase health care costs, which in turn affect the company's bottom line. Companies seek to motivate employees to work hard, be productive, behave ethically, and stay healthy. Managers, like your boss, who seek suggestions to make it easier for employees to balance work and nonwork demands, are taking steps towards valuing employee health. The pressures of workload, job security, and affordability of vacations contribute to the hesitance to take time off.
The notion that someone should be replaced for not increasing vacation days is a matter of company policy and employee negotiation. It is important to note that the feeling of support from supervisors can significantly influence an employee's decision to take that much-needed time off.

Name three factors that are important in promoting venous return
1.The presence of valves 2.the milking action of skeletal muscles 3. the veins as the muscles contract
Venous return is the rate of back flow of blood to the heart. It mainly depends upon the factors such as blood volume, blood pressure, and the cardiac suction.
What is Venous return?Venous return is the rate at which blood flows back to the heart. It limits the cardiac output. Superposition of the cardiac function curve in an organism and venous return curve are used in hemodynamic model preparation.
Peripheral venous pressure is the pressure in the peripheral veins of the body which drains the body organs and tissues. It is the pressure differential between the peripheral and central veins which determines the venous return.
Venous return is facilitated by a number of different factors, including inspiration, increased blood volume, cardiac suction effect, the presence of venous valves and the skeletal muscle pump of the body.

The energy that excites the photosystems is supplied by
Answer:Light energy enters the process of photosynthesis when pigments absorb the light. In plants, pigment molecules absorb only visible light for photosynthesis. The visible light seen by humans as white light actually exists in a rainbow of colors. Certain objects, such as a prism or a drop of water, disperse white light to reveal these colors to the human eye. The visible light portion of the electromagnetic spectrum is perceived by the human eye as a rainbow of colors, with violet and blue having shorter wavelengths and, therefore, higher energy. At the other end of the spectrum toward red, the wavelengths are longer and have lower energy.
Final answer:
Light supplies the energy that excites chlorophyll molecules in photosystems during the process of photosynthesis. This energy transfer initiates electron excitation necessary for the light-dependent reactions, with electrons in Photosystem II being sourced from the splitting of water.
Explanation:
The energy that excites the photosystems is supplied by light. In the process of photosynthesis, light energy is captured by chlorophyll molecules within the photosystems. Specifically, photons are absorbed by chlorophyll, which then transfers the energy to the primary electron acceptor. This energy then excites electrons, which in Photosystem II are sourced from the splitting of water, resulting in the release of oxygen. In Photosystem I, the excited electron comes from the chloroplast electron transport chain. Both photosystems, which contain a light-harvesting complex and a reaction center, absorb different wavelengths of light and are involved in different stages of the light-dependent reactions of photosynthesis.

A plant cell uses the molecules in the list to synthesize a protein. What role do the
ATP molecules play in the protein synthesis process?
Answer:
The light reactions of photosynthesis use chemiosmosis to produce ATP that will be used in the Calvin cycle.
Explanation:
ATP is one of the most important compounds inside a cell because it is the energy transport molecule. ATP (Adenosine TriPhosphate) is considered a transporter of energy (photosynthesis) because when one of the phosphate groups is broken off, turning it into Adenosine DiPhosphate (the Tri means 3 phosphate groups, the Di means 2 phosphate groups). When a phosphate breaks off, through chemical reactions in a cell, energy (photosynthesis) is released which the plant uses for cellular processes.
ATP molecules provide the energy necessary for protein synthesis, enabling the formation of peptide bonds and the loading of amino acids onto tRNA. It also supports the ribosomal movements during translation. ATP is a critical energy source for cellular functions and protein synthesis cannot occur without it.
The ATP molecules play a crucial role in protein synthesis by providing the energy required for various steps of the process. Protein synthesis, specifically during translation, involves decoding an mRNA message into a polypeptide chain, where amino acids are covalently linked by peptide bonds.
ATP is essential as it supplies the biological energy needed for forming these bonds, as well as for other processes such as loading the amino acids onto tRNA molecules, and driving the conformational changes of the ribosome and associated factors that enable the synthesis to proceed.
ATP releases energy when its phosphate bonds are hydrolyzed, which is then used to power the tRNA charging and the ribosomal movements during synthesis. This makes ATP an indispensable molecule in the high-energy-demanding process of protein synthesis. In summary, without ATP, the complex machinery that orchestrates protein synthesis would not have the energy to perform its task, thereby inhibiting the formation of proteins.

Protist arent monophyletic meaning that they don’t a)have one chromosome b)share one common ancestor that isn’t also shared by organisms in other groups c) Live their lifespan in one place but instead can move d) have one mode of reproduction
B. They don’t share ancestors with other organism in the same grouping. Protists belong in a paraphyletic group
Answer:
The correct answer is option B.
Explanation:
Protists are not monophyletic, meaning that they did not represent a single, whole branch of the common life form.
A paraphyletic group is the group of some descendants of a common ancestor. Protists are considered a paraphyletic group.
Example of the monophyletic group is mammals as each and every mammal share a common single ancestor that is not shared by another group of organism.
Thus, the correct answer is option B.

In horses, a black coat is dominant to a brown coat (B = black, b = brown). Long legs are dominant to short legs (L = long, l = short). A black short-legged horse is crossed with a brown long-legged horse. The offspring of the cross is a brown short-legged horse.
a) Identify the genotypes of all three horses.
Answer:
Bb ll for the black short-legged horse
bb Ll for the brown long-legged horse
bb ll for the offspring
Explanation:
In order for the offspring to have the two recessive traits, the parents must have been carrying the recessive genes on at least 1 allele. The first horse is black, but it must have a little b for the offspring to gain a little b from it. The second horse and the offspring are brown, so they must both have two little b's. The same goes for the length of the legs. The first horse and offspring must have two little l's because they have short legs and the second horse must have 1 little l in order for the offspring to inherit 1.
The genotypes of the horses are as follows: the black short-legged horse is Bbll, the brown long-legged horse is bbLl, and the brown short-legged offspring is bbll. These genotypes reflect the recessive nature of the brown coat and short legs phenotype in the offspring.
The genotypes of the three horses involved in the cross can be determined based on the given phenotypes and the known patterns of inheritance for coat color and leg length in horses. A black coat is dominant (B) over a brown coat (b), and long legs are dominant (L) over short legs (l). Here's how the genotypes can be identified:
The offspring is brown with short legs, indicating a recessive phenotype for both traits. Therefore, its genotype must be bbll.The offspring can only get one set of alleles from each parent. Since it is bb for coat color, each parent must have contributed one b allele.The black short-legged parent must be Bbll, having one dominant allele for coat color and two recessive alleles for leg length.The brown long-legged parent must be bbLl, having two recessive alleles for coat color and being heterozygous for leg length.Summary of Genotypes:
Black short-legged horse: BbllBrown long-legged horse: bbLlOffspring (brown short-legged horse): bbllAtoms with certain characteristics are radioactive. which of those below will always be radioactive?

The electromagnetic repulsion of the protons in the nucleus is overcome by strong nuclear forces that keep the nuclear particles together. However, as the atomic number gets bigger so does the size of the nucleus. Therefore, the repulsive electromagnetic forces become greater than the nuclear forces hence the atom becomes unstable. Instability of the nucleus means the atoms become naturally radioactive.

Cesium is a radioactive element which was released into the ocean after the Fuushima nuclear power plant meltdown in 2011. Cesium's half-life is 30 years, which means that for every unit of cesium, half of it will decay over 30 years. How does this affect the human populations that eat fish from this area?
A.) Cesium's half-life is relatively long, so biomagnification could become a concern.
B.) All of the cesium will decay in approximately thirty years; therefore, humans can just avoid eating the contaminated fish for thirty years.
C.) Cesium levels will be acceptable in a short time, so biomagnification is not a concern and humans can eat fish as normal.
D.) Cesium will only decay by half in fifteen years, so human populations should avoid eating fish in this area and avoid contamination
Answer: Option A
Explanation:
A cesium's half life is relatively long( 30 years) which is quite a long period. This element can enter the food chain of the marine ecosystem and can lead to biomagnification.
Bio magnification can be defined as the phenomenon in which there is an increases in the toxic concentration as we move up in the food chain.
Cesium can enter into plankton and form there the concentration of cesium will increase as we will move towards the upper side of the food chain.

The main hormone secreted by the corpus luteum, a temporary gland in the ovaries, is progesterone. It readies the uterus for possible pregnancy and sustains it if fertilization occurs.
Explanation:The principal hormone secreted by the corpus luteum is progesterone. The corpus luteum is a temporary gland formed in the ovaries following the release of an egg during the menstrual cycle. Its main function is to secrete progesterone to prepare the uterus for a potential pregnancy. If no fertilization occurs, the corpus luteum degenerates, leading to a decrease in progesterone levels and the start of menstruation. Progesterone plays a vital role in maintaining the health of the pregnancy as well as preparing the body for childbirth.

Why are birds that inhabit areas with high acid deposition more likely to lay eggs with thin shells?
a.acid deposition acts as an endocrine disruptor that interferes with reproductive hormones in bird species.
b.high rates of cancer due to acid deposition impact birds ability to form eggs.
c.in acidic soils calcium, an important nutrient for eggshell production, washes away and so less is available to birds in their diets
d.acid deposition increases the effects of ddt which has already been implicated in thinning eggshells?
Answer:
C
Explanation:
When it precipitates, the acid in the soil becomes dissolved forming an acidic solution. The low pH solution dissolves the calcium ions in the soil washing them away in runoffs and also leaching them deeper into the soil. This depletes the calcium ions hence making them unavailable to the birds. Calcium intake is important in birds because the ion is a significant component of eggs shells (makes them strong and not brittle hence the eggs don’t break easily)..
A small town in New Mexico discovers that a chemical plant outside of town recently learned that one of their underground pipelines had broken without their knowledge and had been leaking a toxic organic compound for over a month. The spill occurred 5m below the surface in a sandstone above a thin shale bed in the local bedrock. The beds are flat lying and this shale crops out 200m from the chemical plant. The town gets is water from deep wells, about 300m deep. What should the town worry about from this spill?
The major concern for the town in the described scenario is that the freshwater they use from the wells may get polluted by toxic organic compounds that will make the water unsafe and dangerous for usage. The toxic organic compounds have been released for a whole month bellow the surface in a sandstone layer. The sandstone is very easy to penetrate through, so the toxic matter will easily go down through it. As it reaches the lower layers, the shale bedrock comes as the only barrier between it and the freshwater used from the wells. The shale is a soft sedimentary rock, so with enough accumulation of the toxic organic compound it will soon have cracks and the toxic matter will reach the water. Once it mixes with the water, it will pollute it, thus making the deep wells unusable, and the people from the town will be left without their primary source of freshwater which can turn into a catastrophe.

5. Nucleus
6. mRNA
7. Cytoplasm
8. Ribosome
9. Translation
10. anti-codons
11. codon
12. amino acids
13. protein
Explanation:
Deoxyribonucleic acid or DNA hold all the instructions that make up an organism. It determines the physical structure and even the function of the different cells that make up all organisms.
The DNA are all stored in the NUCLEUS of cells. Typically, eukaryotic cells have a nucleus except red blood cells. The nucleus has a nuclear envelope that keeps the DNA stored inside but it has nuclear pores that allows it to interact with the cytoplasm.
In order for DNA to be replicated, it needs to be turned into messenger RNA, otherwise known as mRNA. The mRNA decodes the DNA in order for the cell to use the code. The process is called transcription.
Transcription is done within the nucleus. Before the cell can understand what to do with DNA, mRNA transcribes to know what information it needs to produce specidic proteins.
Once transcription is done, it will then bring the information out of the nucleus and into the cytoplasm. The cytoplasm is the viscous gel-like solution that holds the organelles of the cell. In the cytoplasm you have ribsomes.
Ribosomes is where protein synthesis takes place, this is why it is called the protein factory of the cell. It is a molecule that is made up of ribosomal RNA, which direct the chemical processes involved in protein synthesis. For protein synthesis to happen, it will need another type of RNA, which is the tRNA.
tRNA is transfer RNA and they translate the mRNA sequence into proteins. tRNA have amino acids attached to it.
Each 3 bases of the mRNA are collectively known as codons. These codons correspond with specific tRNA that hold the anticodons. These anticodons code for specific amino acids that they also hold.
When they pair up, the tRNA drop off the amino acid which form a chain with the other tRNA amino acids that complete the code. These chain of monomers then make the protein specific to the DNA code that was copied in the beginning.
