Which best describes an example of conduction? a heater warming a room water boiling in a pot on a stove an ice cube melting in a cup of hot chocolate cold water moving toward the bottom of a swimming pool
Answer:
boiling in a pot on a stove
Explanation:
Conduction is one of the methods of heat transfer (the other two being convection and radiation). Conduction is the direct transfer of heat through a solid medium. The heat causes the molecules of the objects, which are in direct contact with one another to vibrate, hence, passing the heat.
Based on the above description of conduction, the example that best fits this is BOILING IN A POT ON A STOVE. This is because the pot is in contact with the stove, which is the source of the heat. Hence, heat is transferred from the stove to the pot.

The variety of different ways in which species within an ecosystem perform "jobs" that benefit the ecosystem and make it more resilient in the face of change is called ____________.
A. Ecosystem Diversity
B. Functional Diversity
C. Species Diversity
D. Genetic Diversity
E. Biological Diversity
Answer: B. Functional Diversity
Explanation:
Functional diversity can be defined as the component of the biodiversity which is concerned with the range of functions that organisms of an ecosystem perform to sustain their lives. These functionals are important for maintaining the stability in the ecosystem among the members. The organisms can change their functions depending upon the situation of the surrounding environment this is called functional adaptation.

Describe the natural process that creates a human clone.
Answer: Natural cloning also occurs in animal organisms during processes such as budding (offspring grows out of the body of the parent), fragmentation (the body of the parent breaks into distinct pieces, each of which can produce an offspring), and parthenogenesis. In humans and other mammals, the formation of identical twins is a type of natural cloning.

which best describes a gene?
Answer:
Asegment of chromosomal DNA
Explanation:
A gene is a hereditary unit consisting of a sequence of DNA that occupies a specific location on a chromosome and determines a particular characteristic in an organism. Genes undergo mutation when their DNA sequence changes. It is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. However, many genes do not code for proteins. Alleles are forms of the same gene with small differences in their sequence of DNA bases. These small differences contribute to each person's unique physical features.

A sequence of a DNA template strand is shown. 3’ TCC AAT GGC TTA TTT GCA 5’ Which of these is the correct amino acid chain produced from the DNA template strand?
Answer:
Arginine- Leucine- proline- Asparagine- Lysine- Arginine
Explanation:
The correct amino acid sequence for 3’ TCC AAT GGC TTA TTT GCA 5’ would be - Arginine - Leucine - Proline - Asparagine - Lysine - Arginine
The genetic code is stored in a sequence of three nucleotide bases sequence of DNA called base triplets, which act as a template for which messenger RNA (mRNA) is transcribed.
A sequence of three successive nucleotide bases in the transcript mRNA is called a codon.The template strand is one of the DNA strands whose base sequence helps in building mRNA through complementary base sequencing.Template strand or runs in 3'- 5' direction, opposite to the coding strandEach codon code for the specific amino acid.The coding strand for the given template strand would be: 5' AGG UUA CCG AAU AAA GCA 3'Each amino acid code for Arginine - Leucine - Proline - Asparagine - Lysine - ArginineThus, The correct amino acid sequence for 3’ TCC AAT GGC TTA TTT GCA 5’ would be - Arginine - Leucine - Proline - Asparagine - Lysine - Arginine

The image below shows a close-up of the crystals formed in a pegmatitic rock. Which characteristic provides the best evidence that is rock solidified deep underground?
low density
light color
very coarse texture
Answer:
Option C (very coarse texture) is the appropriate one.
Explanation:
Everything always cools quickly because once magma reinforces above that of the ocean floor and perhaps the shape it possesses seems to be agricultural context, color temperature, and so on. But as magma settles down underneath the layer, it gets sufficiently opportunity to solidify, culminating in a much more gritty texture as well as color change, respectively. We then assume that perhaps the assumption of whether concrete solidified buried underground correlates to a rather coarse framework.Other decisions aren't linked to the circumstance issued. So the one above is indeed the best one.

If a DNA strand has 32 % guanine, what percent thymine does it contain?
A) 36%
B)18%
C)64%
D)32%
Answer:
B
Explanation:
Guanine and Cytosine pair together. So, if 32 percent is guanine, then 32 percent should also be cytosine. This is a total of 64 percent. The remaining 36 percent is split between thymine and adenine. So, Thymine will have half of 36 percent which is 18 percent.

Prey is the food of predators, if a prey population decreases, then the predator population decreases. Hence, The prey population is considered a limiting factor.
What are predators?
an animal that preys on other animals and survives by killing and devouring them. predators such as wolves and bears. The natural enemies of rabbits regulate their numbers.
Predation can be classified into four categories: carnivory, herbivory, parasitism, and mutualism. Depending on whether or not the victim dies, each sort of predation can be classified.
The term "prey" refers to the living things that predators eat. Both carnivores and omnivores can be predators. Predators include lions, tigers, sharks, and snakes.
