Both involve the transfer of energy through direct contact.
Answer:
Both transfer thermal energy from warm objects to cooler objects.
Explanation:
Radiation involves the transfer of energy in the form of light, heat and electromagnetic waves such as x-rays while conduction involves the transfer of energy through direct contact of the two substances. The both of them involve involve the transfer of thermal energy from hotter objects to colder objects.
Radiation is involved in the transfer of energy through empty spaces while conduction involves transfer of energy through direct contact.
The statement which best compares radiation and conduction is both transfer thermal energy from warm objects to cooler objects.
To answer the question, we need to know what heat transfer is
What is heat transfer?This is the transfer of thermal energy from one body to the other.
Types of heat transferThere are 3 types of heat transfer namely
Conduction - This is the transfer of thermal energy from warms objects to cooler objects through direct contact. This usually occurs in solids.
Convection - This is transfer of thermal energy from warmer objects to cooler objects by movement of the whole object. This usually occurs in fluids.
Radiation - This is transfer of thermal energy from warm objects to cools objects through empty space by electromagnetic waves.
So, the similarity between conduction and radiation is that both transfer thermal energy from warm objects to cooler objects.
So, the statement which best compares radiation and conduction is both transfer thermal energy from warm objects to cooler objects.

Consuming small amounts of_______can increase menta alertness. C. Consuming______may enhance muscle recovery after intense physical activity. D. An ergogenic aid that increases muscle mass but may also cause uncontrolled growth of the heart or other organs and is banned by the International Olympic Committee is______.
Answer:
Using beta-hydroxy-beta methylbutyric acid (HMB) can improve performance for those who perform explosive repetitions of activity, such as running or lifting weights. Consuming small amounts of caffeine can increase mint alertness. C. The consumption of branched-chain amino acids and creatine can improve muscle recovery after intense physical activity. D. An ergogenic aid that increases muscle mass but can also cause uncontrolled growth of the heart or other organs and is prohibited by the International Olympic Committee: anabolic steroids.
Explanation:
In the answer I leave you the text with the blanks completed ... It is also important that you know that amino acids are important for the formation of muscle mass and its recovery, in addition to creatinine.
On the other hand, these supplements are administered in people who have high performance in sports, and accompanied by a good diet and specific diet, otherwise they will not work.
Anabolics are chemical structures that promote energy reserves and anabolism for muscle tissue hypertrophy, but they do not have a selective effect on the skeletal muscle, but rather affect other parts of the body, that is why they are risky, cause heart failure, cardiovascular, liver, kidney, and even possible alterations of the gallbladder.
An organism is _______ for a gene if it has two copies of the same allele for the gene.
The genotype of an organism and the interaction of the genotype with the environment determine the organism’s _______, or observable characteristics.
The law of independent assortment states that the separation of alleles for one gene are independent of that of other genes, unless the genes are _______.
Mendel’s law of _______ governs which allele is expressed in an individual.
Respond to the following based on your reading.
In the previous section, you learned that the allele for brown eyes (B) is dominant, and blue (b) and green eyes (g) are recessive, while green eyes are dominant over blue eyes. What eye color would someone with the following genotypes exhibit? (a) BB, (b) Bb, (c) gb, (d) Bg, (e) bb.
Discuss the law of segregation and explain why each organism has two copies of the gene for each trait expressed.
What type of experiments did Mendel conduct, and what did he want to find out about the heritability of the seven traits he chose to study?
Answer:
1. Purebred (N.B: the exact word is considered a foul word)
2. Phenotype
3. Linked
4. Segregation
5) (a) BB- Brown eyes
(b) Bb- brown eyes
(c) gb- green eyes
(d) Bg- brown eyes
(e) bb- blue eyes
The other questions are explained below
Explanation:
1. A purebred organism is that which possess two copies of the same alleles in its genotype. An allele is a contrasting form of a gene. If the two alleles are the same, the organism is said to be purebred.
2. Phenotype of an organism is the observable characteristics of the organism. It is determined by the organism's genotype in interaction with its environment.
3. Mendel's law of independent assortment states that the alleles of a gene will separate into gametes independently of another gene unless the genes are linked. Linked genes are genes that are too close to each other on a chromosome and hence, do not sort independently. They're rather inherited together.
4. Mendel’s law of Segregation governs which allele is expressed in an individual. According to this law, an organism will express the allele it randomly receives from each parent. If an organism receives two different alleles, it will express the allele that is dominant. In other words, an organism will only express the recessive trait if it receives two recessive alleles from both parents.
5. a) BB- Brown eyes because the organism is purebred for the dominant (brown) allele
(b) Bb- brown eyes because the brown allele (B) will mask the expression of blue allele (b) and express itself.
(c) gb- green eyes because the allele for green eyes (g) is dominant over the allele for blue eyes.
(d) Bg- brown eyes because the brown allele (B) is dominant over the allele for green eyes (g), hence, it will mask its expression
(e) bb- blue eyes because the organism is purebred for the blue allele i.e. same recessive (blue) alleles in the gene.
6. The law of segregation as proposed by Mendel states that the alleles of a gene will separate into gametes during gamete formation (meiosis). This is done in such a way that each gamete contains only one allele of each gene. Hence, an organisms will contain two copies of a gene because they receive each copy (allele) from each parent during fusion of their gametes.
7. Mendel conducted an hybridization experiment i.e. a cross involving two individuals that possess different traits. He did this in order to find out how different traits/characteristics in organisms were transferred from one generation to another. Mendel chose the pea plant for his experiment because they could easily be manipulated for self and cross pollination. Mendel studied seven (7) different traits or characteristics in pea plants including height, seed shape, seed color, flower color etc.

what are the problems and the challenges in classifying living things
Answer:
below
Explanation:
there are so many different kinds of living things that its so difficult to classify them as there would be too many classifications that it would become absurd to have only a few organsims in a single group. the role of classification is to organize as well as simplify so it proves to be a challenge when the subgroups branching from eukoryotes vs prokaryotes become too small and therefore it becomes a giant mess. even the current classification system (taxonomy) is flawed.
The problems/challenges associated with classifying living things is : The challenge of having a very small number of living thing classified into a subgroup and having an enormous amount of subgroups.
Although the main reason of classification of organism is to organize/categorize every living thing into a suitable group as well as simplify the subgroups( this leads to having a lot of subgroups ). there is also a challenge whereby the subgroups become so small when trying to categorize every organisms following all the rules of taxonomy. while
Taxonomy is the science of classifying living things into different groups and subgroups following certain similar characteristics exhibited by the organism.
An example is : The subgroups of eukaryotes vs prokaryotes becoming too small. because the rules of Taxonomy been followed.
hence the challenges are: very small number of living thing classified into a subgroup and having an enormous amount of subgroups.
