Answer:
A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another; the levels in the food chain are producers, primary consumers, higher-level consumers, and finally decomposers.
Explanation:
Answer:
The flow of energy is always unidirectional. The energy passes from primary producers to primary consumers. From the primary consumers, the energy is passed to secondary consumers and then to tertiary consumers. Thus the energy pyramid is always upright.

represses gene transcription and promotes mRNA translation.
determines which end of the egg will become the head and which end will become the tail.
is found only in adult somatic cells.
Answer:
represses gene transcription and promotes mRNA translation.
Explanation:
Homeotic gene refers to any group of genes that controls the pattern of formation of body structure during early embryonic development of organisms. These genes encode proteins which is called transcription factors that direct cells to form various parts of the body. Homeotic genes is the master control genes that regulate other groups of genes that are responsible for the development of body parts that will develop in different locations.

DNA replication is said to be semiconservative. Which of the following statements correctly explains what this means?
Answer: DNA is a double stranded molecule. When DNA is copied the two strand of DNA (old strands) separate and new nucleotides match up with the two separated strands.
This process creates two identical double stranded DNA molecules are formed. Each DNA molecule contains one strand of the original DNA molecule and one newly synthesized (made) strand.

The semi-conservative nature of DNA replication illustrates that each strand in the DNA double helix function as a template for the synthesis of a new or complementary strand.
What is DNA replication?DNA replication may be defined as a type of biological process that deals with the synthesis of two identical replicas of DNA from one original DNA molecule during cell division.
The semi-conservative model of DNA was proposed by Watson and Crick. This model implies that each double helix of DNA is composed of one new and one old strand.
In semi-conservative replication, the parental double helix is half conserved and each parental single strand remains intact.
Therefore, DNA replication is said to be semi-conservative due to the process of each new double strand consisting of one parental strand and one new daughter strand.

When exercising routinely, timing the food that you eat around your exercise activities is important. Carbohydrate intake is particularly influential, with different ideal timings for simple carbohydrates and complex carbohydrates. The best types of carbohydrates to eat during and/or immediately after exercise are simple carbohydrates, whereas complex carbohydrates are ideally consumed a couple of hours before exercise. Complex carbohydrates take longer to digest and enter the bloodstream and can help build glycogen stores.
Sort the following food items into their respective bins based on whether they are simple, complex, or noncarbohydrate-rich foods.
Drag the appropriate items into their respective bins

Why does a floating leaf indicate that photosynthesis is occurring?
Answer and Explanation:
A floating leaf indicates that photosynthesis is occurring because it means the leaf is producing oxygen, a biproduct of photosynthesis. It is possible that photosynthesis is occurring in a leaf that is not floating because it's possible that the leaf is denser than the solution and can't float.

On the planet Kermit, in the Muppet population, there are two autosomal loci of interest. The first locus has alleles A and a, and the second locus has alleles B and b. A and B are the dominant alleles at the respective loci. The loci act in an epistatic manner, identical to the way two genes interact to produce coat color in labradors. The phenotype here is muppet hair color. We have the following results:
Muppet hair color as a function of two-locus genotypes
Two-locus genotype Muppet hair color
A_B_ Cookie monster blue
aaB_ Elmo red
