# To See Why, Calculate The Energy Absorbed From Your Body If You Eat 0.70 Kg Of -9 C Snow Which Your Body (2023)

Biology High School

The energy absorbed from the body = 302.82 J

Explanation:

Note: a Snow is an an ice

The heat absorbed from the body = heat required to change the temperature of snow from -9 °C to 37 °C. + The latent heat of snow

H = c₁m(t₂-t₁) + c₂m ........................... Equation 2

Where H = heat absorbed from the body, c₁ = specific heat capacity of ice, c₂ = specific latent heat of fusion of ice, m = mass of ice.

Given: m = 0.7 kg, t₂ = 37 °C, t₁ = -9 °C

Constant: c₁ = 2.1 g/g.°C, c₂ = 336 J/g

Substituting these values into equation 1,

H = 0.7×2.1×(37+9) + 0.7(336)

H = 67.62 + 235.2

H = 302.82 J

Thus, the energy absorbed from the body = 302.82 J

In vitro, free oligonucleotides, such as mRNA transcripts, have a short half-life in the cytosol. What mechanism is used to stabilize these molecules?

Explanation:

This is the mechanism of adding a poly(A)tail to a mRNA to protect the RNA.This tail is made up of adenosine monophosphate(AMP) compound, and therefore consists of only this purine base stretch.(adenine is purines).

Polyadenylation participate in production of mature mRNA for the process of translation in the cystosol, therefore ensuring stability.

However this tail shortened with time, and in extreme shortness the mRNA is degraded by enzymes in the cells.

Conclusively, the protection provided by the poly(A) tail

and production of mature mRNA ensured the stability of these molecules

The complete question is as follows:

When considering the applicability of the Americans with Disabilities Act (ADA) and other disability related laws to research activities involving subjects who are decisionally impaired, researchers must:

The correct answer is "determine if the research is 'targeting' a disabled population".

Subjects that are decisionally impaired are people that for numerous reasons are not able to provide an autonomous consent about participating in a study. Since subjects that are decisionally impaired can be suffering from psychiatric, organic, developmental or other types of disorders, sometimes is not clear if a study is 'targeting' a disabled population. In these cases, the Americans with Disabilities Act (ADA) and other disability-related laws to research activities must determine it.

What is independent assortment? During which phase(s) of meiosis does independent assortment occur and what is the significance ofthis process?

independent assortment occurs in metaphase I and anaphase I

Explanation:

Independent assortment is the development of haphazard combinations of chromosomes in meiosis and of genes on separate pairs of homologous chromosomes through the passage as stated by the laws of probability i.e one of each diploid pair of homologous chromosomes pairs into each gamete independently of each other pair. This principle describes and demonstrates how different genes independently separate from one another when reproductive cells develops.

Part of the significance of independent assortment is to produce new genetic combinations that increase genetic variations within a population.

To increase the genetic diversity in the offspring.

What evidence must be considered when determining whether or not a trait is an adaptation

An adaptation can be viewed as a trait that emerged and developed for a certain condition so as to increases the organism changes of survival or fitness.

For a trait to be called adaptive, it must have had a positive influence but not majorly a trait that develops in reaction to a certain selection pressure.

Categorically, a trait is seen as adaptation if it is the aftermath of selection, and adaptive if it is of favourable influence at the existing time.

An adaptation is a trait that "evolved" for a particular condition that allows the animal to survive. Something is adaptive if it is a useful trait but not necessarily one that occurred in response to a particular selection pressure. Basically a trait is an adaptation if it is the product of selection, and adaptive if it is beneficial in the present time.

Once DNA is collected at a crime scene, it must be processed in the lab. If there is a limited quantity of DNA available, what step must the technician take in this process?

PCR is used to amplify the DNA.

Explanation:

PCR is acronym for polymerase Chain Reaction, a molecular biology procedure for amplifying segments of DNA, through the production multiple copies with the aid of the enzyme DNA polymerase under controlled factors. In PCR, thermal cycling or the continuous heating and cooling of the sample for DNA melting and replication is employed.

In this case, Once DNA is collected at a crime scene, it must be processed in the lab. But the DNA obtained was of limited quantity therefore it is advisable for the technician to amplify the DNA using PCR.

What other hypotheses can you suggest concerning yeast's ability to use fermentation to make atp? (refer to "alcohol" page in lab 2)?

Yeast has the capacity to employ fermentation as a tool to obtain ATP energy. I would suggest the hypothesis that, a very high concentration of sugar would eliminate the yeast causing little or no cellular respiration activities.

An organism has 3 pairs of chromosomes. How many different combinations of chromosomes are possible as a result of meiosis if crossing over or chromosomal mutations do not occur?

2^3= 8 possible combinations

Explanation:

Mendel discovered in his experiments that a pair of chromosome in an organism consists of two similar but non-identical chromosomes called HOMOLOGOUS CHROMOSOMES in which each comes from each parent.

During meiosis, each homologous chromosomes get sorted into gametes in accordance to Mendel's law of segregation and independent assortment.

For each chromosome, a variant form of gene called allele is gets randomly sorted into gametes to form 8 possible combinations for an organism with three (3) pair of chromosomes.

Possible number of combination of gametes is determined by the formula 2^n, where n is the number of character or chromosome pair in this case.

Hence 2^3= 8 possible chromosomal combinations of gametes produced by meiosis.

Which term describes learning that takes less time because the brain has already stored some of the information needed

Learning is the process of gaining new knowledge, habits, abilities, beliefs, or preferences or changing ones, relearning that already exist.

What is learning?

Humans, animals, and some robots all have the capacity to learn, and there is evidence that some plants also have some capacity for learning.

While some learning is quick and brought on by a single occurrence (such as getting burned by a hot stove), many skills and knowledge are developed over time through repeated experiences.

Therefore, relearning the process of picking up new information, skills, values, attitudes, and preferences is known as learning. It's a lengthy procedure that takes at least 12 to 16 years.

Design a planned community that preserves biodiversity and accommodates the human population

Explanation:

Humankind is facing many environmental challenges, such as climate change caused by global warming, pollution, deforestation, oil spills, the use of non-biodegradable materials and others.

These effects were largely caused by the shift from rural to industrial society, as there were several environmental changes and increased use of natural resources.

But there is a greater population awareness of environmental preservation, and this is the starting point for the creation of a society that protects biodiversity. When the population becomes aware of the importance of prevention and protection of the environment, it consequently forces companies to be more socially and environmentally responsible and that the legislation becomes stricter for prevention. There are also easy measures to be performed on a daily basis, such as waste reduction, the use of smart systems that generate green energy, water collection and reuse, reduced consumption of red meat, greater use of non-polluting transport and others.

What causes hemoglobin to unload more oxygen to metabolically active tissues such as skeletal muscles during exercise?

Answer: The Bohr Effect allows for enhanced unloading of oxygen in metabolically active peripheral tissues such as exercising skeletal muscle. As more metabolism takes place, the carbon dioxide partial pressure increases thus causing larger reductions in local pH and in turn allowing for greater oxygen unloading.

Identify TWO specific human activities that result in a loss of aquatic biodiversity and explain how each activity lowers aquatic biodiversity.

Aquatic biodiversity refers to the different species of plants and animals that live in the aquatic environment, i.e. ocean, lakes.

• A wide array of human activities affect aquatic biodiversity.
• Some of these activities include hunting, habitat destruction, and foreign species importation.
• Importing foreign species disbalances the local biodiversity that often proves harmful for the local aquatic biodiversity.
• Hunting is the direct destruction of biodiversity by killing aquatic species just for the purpose of fun and pride.

Thus, two activities affecting aquatic biodiversity are hunting and importing foreign species.

Homologous chromosomes separate from each other in: meiosis II. They never separate from each other during any form of cell division. meiosis I. mitosis.

Explanation:

Generally, meiosis is a type of cell division where four gamete cells are produced, this occurs when the number of chromosomes in the parent cells is reduced by half. This process can be divided into meiosis I and II.

In meiosis I, the reproducing organism produces reproductive cells. The nucleus is divided into four nuclei, and each containing half of the chromosome number, This result in spores formation in plants and gametes in animals. The meiosis I is also known as reduction division.

Meiosis II is similar to mitosis. Mitosis occurs to replace dead or damaged cells and to replace cells with short life span.

What is the relationship between temperature and kelp productivity?

Kelp productivity is inversely related to temperature. It may be characterized as when the temperature of a region gradually rises, the productivity of kelp declines.

What is Kelp?

Kelp may be defined as a large, brown plant that significantly grows in the part of the sea and will be utilized in some food sources and medicines. In a more simple sense, kelp may also be characterized as a mass of large seaweeds.

According to various research, it may be concluded that Kelp forests grow best in temperature ranges between 5-20°C. Apart from this, they also need nutrient-rich space with clear and transparent water.

They must be clear in order to reach the sunlight on the ocean floor. It may be the characteristic feature that if the water is too warm or the temperature is too high, the population of kelp does not survive as well as compared to normal.

Therefore, kelp productivity is inversely related to temperature. It may be characterized as when the temperature of a region gradually rises, the productivity of kelp declines.
