Answer:
a. Obesity is associated with lower amounts of UCP1.
c. The set-point theory suggests that the body responds to both energy restriction and overeating with physiological changes to maintain its weight within a narrow range.
Explanation:
Correct statements:
a. Obesity has been associated with a low expression of the UCP-1 gene in the brown adipose tissue. For example, in transgenic mice, it has been shown that the overexpression of the UCP1 gene is associated with the stimulation of fatty acid oxidation.
c. The set point theory indicates that the human body has a preconfigured weight which is based on information contained in the genome. In consequence, the set point theory states that fluctuations in weight are limited, where there are people that have higher weight set points compared to other persons, and inherent natural mechanisms in the body try to maintain within these ranges.
Incorrect statements:
- Genetic factors account for 50-80% of the body mass index (BMI). The remaining value is due to environmental factors and the interaction between a genotype and the environment.
- The Fat mass and obesity-associated gene (FTO) is a gene located on chromosome 16 which encodes for the alpha-ketoglutarate-dependent dioxygenase enzyme. Although it has been suggested that some allelic variants of this gene are associated with obesity, this gene is always expressed (i.e., constitutively expressed) in the hypothalamus, where its expression is linked to the food intake.
- The 'thrifty gene' theory states that gene variants (alleles) evolved to favor a more efficient use of nutrients, thereby promoting diseases associated with an excess of calories such as obesity and type 2 diabetes.
The correct statements about biological influences on body weight include:
Obesity is associated with lower amounts of UCP1.The set-point theory suggests that the body responds to both energy restriction and overeating with physiological changes to maintain its weight within a narrow range.People who have the fat mass and obesity (FTO)-associated gene are generally heavier than those without the gene.It should be noted that there are biological influences that affect the weight of a person.
The individuals who have the fat mass and obesity (FTO)-associated gene are generally heavier than those without the gene. Also, obesity is associated with lower amounts of UCP1.
In conclusion, the correct options are A, C, and E.

Is biodiversity renewable or nonrenewable?
Answer:
renewable
Explanation:
Biodiversity refers to the variety of plant and animal wild life in the world or in a particular habitat which is important in that specific location. Renewable is anything that recycles itself through its consumption. Which is what happens in biomes. Life dies off and provides the necessary resources for new life to be reborn and so on, thus making Biodiversity renewable.
When the concentration of a substance higher on one side of the cells selectively permeable membrane, certain molecules may move by osmosis or diffusion through the membrane without the cell using any energy. This process is called
A.passive transport
B.active transport
C. Mitosis
D. Replication
Answer:
A.
Explanation:
osmosis and diffusion are both passive transport bc it doesnt require energy and only moves down cocentration gradient, never against concertration gradient. Give me a brainliest if i helped! ♡
When certain molecules may move by osmosis or diffusion through the membrane without the cell using any energy, the process is called passive transport.
When diffusion takes place between compartments separated by a membrane permeable to that solute, it is called simple diffusion.
Passive transport does not require any additional energy other than the movement of the molecules, moving these in favor of their concentration gradient.
In other words, simple diffusion does not require ATP expenditure, since it is a spontaneous phenomenon.
The molecules that are mobilized by simple diffusion through the membrane are the nonpolar and small, the fat-soluble and the small polar ones, but without a net electric charge, such as H2O.
In the particular case of H2O, passive transport is called osmosis, the passage of water through the membrane by osmosis always takes place spontaneously and very quickly.
H2O will diffuse from the compartment with the lowest concentration of solutes or hypotonic medium, to the compartment with the highest concentration of solutes or hypertonic medium, in such a way as to equalize the concentrations in both compartments.
Therefore, we can conclude that when certain molecules may move by osmosis or diffusion through the membrane without the cell using any energy, the process is called passive transport.

How do the hypothesis of microspheres and the RNA World hypothesis build off of each other?
Answer:
Microspheres are formed of proteins. It has been found that when an amino acid is permitted to get desiccated, then this amino acid produces proteins that in turn give rise to microspheres.
On the basis of the RNA world hypothesis, the first genetic substance was considered to be an RNA, and then later the DNA turned out to be the genetic substance of higher species during the passage of evolution. It was also believed that microspheres comprised encoded information within it, and at the time of the splitting of microspheres, this encrypted information may have got transferred to the upcoming generation.

9) What trend do you notice about carbohydrates in the graph above?
your help is appreciated thanks ! :)
Answer:
carbohydrates burn within 2 hours after eating while lipids last 6 hours
Explanation:
carbohydrates are short term energy
and lipids are longer term of energy
The trend which can be noticed about carbohydrates in the graph above is that it increases the blood sugar level than the other food type.
In Science, biological macromolecules are mainly grouped into four (4) categories and these are;
Lipids.Nucleic acid.Proteins.Carbohydrates.Carbohydrates are typically found in energy-giving foods and they aid in the proper functioning of the body of a living organism such animals and human beings.
Also, carbohydrates are broken down in the body into sugar but not proteins or fat.
This ultimately implies that, an increase in the intake of carbohydrates can cause a subsequent increase in the blood sugar level.
Based on the graph above, we can deduce that carbohydrates increases the blood sugar level than the other food type.

An earthworm taking in soil for nutrition
Answer:
earthworm taking soil for nutrition
Explanation:
it's consuming the energy unlike the rock
An earthworm taking in soil for nutrition is another example of an open system, option B is correct.
An open system is characterized by its ability to exchange matter and energy with its external environment. In the case of an earthworm, it actively takes in soil for nutrition, breaking down organic matter and absorbing nutrients through its digestive system. This process allows the earthworm to grow, reproduce, and carry out essential life functions.
The exchange of soil, nutrients, and gases (such as oxygen) occurs continuously, sustaining the earthworm's biological activities. In contrast, a rock in a field does not interact with its environment in the same way. It remains a closed system, passively experiencing natural forces without actively receiving external inputs or engaging in metabolic processes, option B is correct.

Answer the following question. How might the human condition be improved through biological and environmental
engineering?
Answer:
This chapter examines the range of human consequences of, and responses to, global environmental change. We begin by developing the concept of human consequences and showing why, to understand them, it is critical to understand the variety of human responses to global change. We then offer a framework for thinking about human responses and discuss the pivotal role of conflict. The next section examines three cases that illustrate many of the major factors influencing the human consequences of global change. The following sections describe the human systems that are affected by or respond to global change, and how they interrelate. We conclude by offering some general principles for research and some research implications.
