What do amino acids, fatty acids, and sugars (monosaccharides) have in common?
A. They are made of carbon, oxygen, and nitrogen.
B. They are made of carbon, oxygen, and hydrogen.
C. They are used to make lipids.
D. They are used to make proteins.
Answer:
Explanation:
C. They are used to make lipids.
What amino acids, fatty acids, and sugars (monosaccharides) have in common is that they are made of carbon, oxygen, and hydrogen which is option B.
Amino acids are the basic structural units of proteins. Each amino group (-NH₂) and a carboxyl group (-COOH) in its molecule. Thus, from the molecular structure of an amino acid, the carboxyl group of the molecule contains carbon, oxygen and hydrogen elements.
Fatty acids are commonly found in lipids ans are made up of long chain alkanoic acids of general formular, RCOOH where R contains about 10 to 18 carbon atoms. the terminal -COOH group contains carbon, oxygen and hydrogen elements.
Sugars (monosaccharides): they are naturally occuring organic compounds containing carbon, hydrogen and oxygen, with the hydrogen and oxygen present in the ratio of 2:1. The general formula for monosaccharides is C₆H₆O₁₂.
Therefore, amino acids, fatty acids, and sugars (monosaccharides) have carbon, oxygen, and hydrogen in common.

A species of Coral snake has a red, yellow and black stripe pattern. One
gene controls if the stripes are thick or thin. Thin (T) is dominant over
thick (t). If two snakes heterozygous for this gene are crossed, what will
be the genotype(s) of their offspring? You may need to use a Punnett
square to answer the question.
Question Progress
OA. TT and Tt
B. TT, Tt, and tt
C. TT and tt
D. All Tt
The genetic attributes of the organism are determined by the genotype. The cross of the heterozygous genes in Coral snakes results in offsprings with TT, Tt, and tt. Thus, option B is correct.
What are genes?Genes are the functional and physical basis of the inheritance that passes from generation to offspring with various traits and attributes. The gene contains a recessive and a dominant allele.
Heterozygous genes are represented as Tt as it contains one dominant and one recessive allele. The cross between the two heterozygous (Tt) Coral snakes is attached to the image below.
From the cross, it can be seen that 75 % of the coral snakes have thin strips while the 25 % of the species have thick strips. The ratios are:
Genotype = 1 : 2 : 1
Phenotype = 1 : 3
Therefore, option b. the genotype(s) of the offspring will be TT, Tt, and tt.

Growers often wrap potted plants in plastic sleeves prior to shipping. If plants remain in these sleeves too long, their leaves curl and fall off. Imagine you are working at a garden center and have been asked to make a presentation to a local garden club. Unit 5 DQ Question: Explain the processes that may cause the leaves to drop and fall.
Answer:
Shock, age and climate.
Explanation:
The processes that may cause the leaves to drop and fall are shock, age and climate. The plants drop their leaves due to shock when they experience by transplanting from place to another. When the leaves get older having yellow colour so due to no function it falls. The climatic condition is also responsible for the dropping of leaves. Those plants which can't grow in cool season so when the winter comes they shed their leaves and wait for the summer season.

What can increase the rate that lactic acid is removed from the muscles?
A. A cool-down exercise
B. Drinking water
C. Stop exercising immediately
D. Applying a muscle cream with a base to neutralize the acid
The rate at which lactic acid is removed from the muscles can be increased by DRINKING WATER
HOW LACTIC ACID FORMS IN MUSCLES:
Lactic acid is produced in the muscle cells when there is lac of or insufficient oxygen to perform aerobic respiration. During vigorous exercise e.g. running, oxygen is used up faster, hence, causing cells to switch to anaerobic respiration (fermentation) leading to the build up of lactic acid.WAY TO HELP THE BODY GET RID OF LACTIC ACID IN MUSCLE CELLS:
Lactic acid buildup often comes with pain and soreness in the muscles. However, the rate of removal of lactic acid in the muscle cells can be increased by staying hydrated (drinking water) prior to, during and post exercise.The rate at which lactic acid is removed from the muscles can be increased by DRINKING WATER.

change the hypothesis if mussels died in
both aquariums?
The new hypothesis could be that there is another alternative factor that is negativey afecting dwarfs survivorship.
The previous hypothesis of high levels of phosphate killing mussels is not necessarily disproved. But the death of mussels from both the control and the treatment groups might be related to one of the controlled variables that could be actually afecting them.
----------------------
Probably different levels of phosphate are also affecting invididuals´ survivor rates. However, the fact that mussels from all the aquariums died suggests that there is something else going on that caused the death of all the individuals.
The control group is used to identify any other factors influencing the results obtained in the study, apart from the modified variables of the treatment. Individuals of the control group are selected from the same population as the treatment group. These two groups are identical in all aspects except for the independent variable, which changes in the treatment group but remains constant in the control group.
We know that mussels in this experiment were taken from the same population and grown under the same controlled conditions. Only the treatment group received phosphate, but all mussels died, not only the ones that receive phosphate. This result turns to be useful because it is indicating that there is another variable that is killing mussels. Phosphate might be a cause of death, but there is also something else. So the researchers should pay attention to the controlled variables, such as water quality, temperature, pH, food supply, light exposure, or others.
These variables might be reflecting the real conditions under which mussels live. The results tell that one of these is related to individual death and could be a consequence of climate change or soil use, among other causes.

what are the four postulates of "the theory of inheritance of acquired characters”?
Summary of four postulates of the theory of inheritance of acquired characteristics:
1. Living organisms or their component parts tend to increase in size.
2. Production of new organ is resulted from a new need.
3. Continued use of an organ makes it more developed, while disuse of an organ results in degeneration.
4. Acquired characters (or modifications) developed by individuals during their own lifetime are inheritable and accumulate over a period of time resulting a new species.
Explanation:
1. New needs:
Every living organism is found in some kind of environment. The changes in the environmental factors like light, temperature, medium, food, air etc. or migration of animal lead to the origin of new needs in the living organisms, especially animals. To fulfill these new needs, the living organisms have to exert special efforts like the changes in habits or behaviour.
2. Use and disuse of organs:
The new habits involve the greater use of certain organs to meet new needs, and the disuse or lesser use of certain other organs which are of no use in new conditions. This use and disuse of organs greatly affect the form, structure and functioning of the organs.
Continuous and extra use of organs make them more efficient while the continued disuse of some other organs lead to their degeneration and ultimate disappearance. So, Lamarckism is also called “Theory of use and disuse of organs.”
So the organism acquires certain new characters due to direct or indirect environmental effects during its own life span and are called Acquired or adaptive characters.
3. Inheritance of acquired characters:
Lamarck believed that acquired characters are inheritable and are transmitted to the offsprings so that these are born fit to face the changed environmental conditions and the chances of their survival are increased.
4. Speciation:
Lamarck believed that in every generation, new characters are acquired and transmitted to next generation, so that new characters accumulate generation after generation. After a number of generations, a new species is formed.
