The following indicates that an endothermic reaction has occurred when temperature decreases, which is in the last option as the endothermic reaction needs heat to carry out the reactions.
What is the significance of the endothermic reaction?There are two types of reactions, such as the reaction that requires heat to form the product, the endothermic reaction, while some of the reactions that release heat are called the exothermic reaction, and the exothermic reactions have more energy at the reactant side than the product side. In the case of a endothermic reaction, the product usually has more energy than the reactants, and the change in free energy here is positive.
Hence, the following indicates that an endothermic reaction has occurred when temperature decreases, which is in the last option as the endothermic reaction needs heat to carry out the reactions.

Answer:
A section of DNA that provides instructions for building a specific protein and A packet of genetic information that can be passed down from one generation to the next
Explanation:
A DNA molecule is not a gene, it is a nucleotide. The entire collection of genetic information in a given species results isn't a gene although many genes comprise what is the genome. Given that those two answers are not what genes are, the other two options are correct.

Suppose we completely stopped burning fossil fuels immediately. How many years would it take to return to atmospheric CO2 levels from the year 1800, about 600 GtC? Use the Gizmo to find the answer.
Answer:
Explanation:
It would take 50 years to return to atmospheric CO2 levels from the year 1800. I know this because I set the fossil fuel usage to 0 and proceeded to simulate 50 years and that’s when the atmospheric CO2 levels returned to 600 GtC.
As per observation It could take 50 years to go back to atmospheric CO2 degrees from the yr 1800.
Each year, there has been no extrade in the quantity of CO2 withinside the ecosystem because of soil and land plants. coal also can be the answer.
What is co2 quantity ?Since 2000, the worldwide atmospheric carbon dioxide quantity has grown with the aid of using 43.5ppm, an growth of 12 percent. The contemporary-day document of atmospheric carbon dioxide degrees commenced with observations recorded at Mauna Loa Observatory in Hawaii.

What is the difference between reproduction and heredity?
Reproduction is the process of passing on traits, whereas heredity is the process of
producing offspring
Reproduction is the process of producing offspring, whereas heredity is the process
of passing on traits.
Reproduction always involves changes in inherited characteristics, whereas heredity
does not
Heredity always involves changes in inherited characteristics, whereas reproduction
does not
Answer:
Reproduction is the process of producing offspring, whereas heredity is the process
of passing on traits.
Explanation:
PLEASE MARK BRAINLIEST, if you think this is correct and best! Thanks!
Reproduction generally means making copy of something, like giving birth/breeding, duplicating.
Heredity is inheritance of traits/ passing on traits from parents t thsir child/children through genes. It makes children have same traits as their parents and looks so what same like their parents!
They definitely aren’t same!
Reproduction is the process of producing offspring, whereas heredity is the process of passing on traits.
What do you mean by heredity?Heredity, also called inheritance or biological inheritance, is the passing on of traits from parents to their offspring; either through asexual reproduction or sexual reproduction, the offspring cells or organisms acquire the genetic information.
Heredity explains why offspring resemble, but are not identical to, their parents and is a unifying biological principle. Heredity refers to specific mechanisms by which characteristics or traits are passed from one generation to the next via genes.
Heredity can be defined as the transfer of genetic characters from parents to offsprings by the process of fertilization, where the nuclei of male and female gamete fuses with each other and forms the genetic material of the zygote.

Mary Simpson
This flower must have grown in neutral soil, with little aluminum.
In some varieties of bigleaf hydrangeas (Hydrangea macrophylla), soil pH determines whether the plant will produce blue or pink flowers. Blooms appear bluest when grown in acidic soil with a pH in the 5.0 to 5.5 range. The same cultivar may sport pink blossoms in soil with a more neutral pH, such as 6.5 to 7.0. Florists control flower color by potting soil mixture

20. Lipids
21. Lipids
22. Carbohydrates
23. Lipids
Explanation:
Carbohydrates are organic molecules composed of carbon, hydrogen and oxygen. Carbohydrates can be classified into three types: monosaccharides (e.g. glucose), disaccharides (e.g., lactose), and polysaccharides (e.g., starch). Cellulose is a carbohydrate where many glucose rings chain together, while chitin is a polysaccharide consisting of chains of modified glucose molecules.
Lipids represent a diverse group of organic molecules that include, among others, fats, waxes, oils, hormones, etc. Lipids play a role by insulating (and protecting) the body. For example, there is a layer of fats beneath the skin which enables to maintain body temperature relatively constant. In animals, lipids constitute about 50% of the mass of cell membranes. These membrane lipids are mainly phospholipids, glycolipids and cholesterol. There are hormones that derive from lipids such as steroid hormones, which derive from cholesterol. Some examples of steroid hormones are testosterone, estrogen and cortisol.

What groups of organisms are most in danger of extinction?
A. Those with small population
B. Those that migrate or need special habitats
C. Those with large populations that breed quickly
D. Both a and b
Explanation:
D.Both a and B
As organisms with small population and those who migrate and need special habitat are most in danger of extinction.
The group of organisms that are in danger of extinction is those that have small populations and those that migrate or need special habits. So the correct option is D.
What is the extinction of species?
In biology, extinction refers to the extinction or death of a species. Extinction happens when a species' numbers are reduced due to evolutionary changes in its members, such as genetic inbreeding, poor reproduction, and population decline, or due to environmental factors like habitat fragmentation, climate change, natural disasters, and overexploitation of the species for human use.
The majority of species that have ever existed on Earth have gone extinct, but the fossil record indicates five very significant extinctions, known as mass extinction events, each of which resulted in the extinction of enormous numbers of species. The bulk of extinctions, which happen continuously and are described as background extinctions, are separated from these glaring decreases in the variety by the term "mass extinction."
Therefore, the correct option is D.

Explanation:
The rate of chemical is a measure of the speed of a chemical reaction.
The measurement of the reaction rate is based on the disappearance of a reactant or appearance of a product with increasing reaction time.
Reaction rate is usually expressed in terms of a change in concentration of the chosen reactant or product per unit of time.
During a reaction, the concentration of the reactant decreases exponentially with time while that of a product increases exponentially with time.
Reaction rate = [tex]\frac{change in concentration of a reactant/product}{Time taken}[/tex]
