Why do structural similarities between living things point to common ancestry?
Explanation:
Comparative anatomy is the study of the similarities and differences in the structures of different species. Similar body parts may be homologies or analogies. Both provide evidence for evolution. ... The structures are similar because they evolved to do the same job, not because they were inherited from a common ancestor.
What are two ways that meiosis contributes to genetic variation? How do these two ways lead to variation?
Answer:
During prophase of meiosis I, the double-chromatid homologous pairs of chromosomes cross over with each other and often exchange chromosome segments. This recombination creates genetic diversity by allowing genes from each parent to intermix, resulting in chromosomes with a different genetic complement.Hope this is fine for you!!The process of animals relocating to different environments in response to seasonal changes is called:
Explanation:
Many birds, such as geese, seasonally fly to warm places when the weather gets cold. They then return when the weather warms. This process is called migration. ... Migration enables many animals to move to places where it is easier for them to survive.

Explanation:
Cuando una celula se va a dividir, la cromatina se contrae y compacta y forma estructuras como la que se ve al lado. Diga qué nombre reciben estas estructuras y cuantas hay en una célula humana
Answer:
cromosomas
Explanation:
Los cromosomas son moléculas lineales de ADN que contienen parte o todo el material genético de un organismo. El ciclo celular se divide en dos etapas: 1-interfase o etapa de 'no división' y 2-división celular. Durante la interfase, las fibras de cromatina no poseen un grado de condensación suficiente como para hablar de cromosomas. Durante la primera etapa de división celular (es decir, durante la profase), las fibras de cromatina se condensan para formar estructuras compactas conocidas como 'cromosomas' los cuales serán distribuidos entre células hijas. Las células somáticas de los seres humanos son diploides (2n = 46 cromosomas), esto significa que contienen 23 pares de cromosomas homólogos los cuales se alinean durante la metafase de la mitosis en la placa ecuatorial de la célula para ser distribuidos equitativamente entre células hijas durante las fases posteriores del ciclo celular (anafase, telofase y citocinesis). Por otra parte, las células germinales o gametos (espermatozoides masculinos y los óvulos femeninos) son haploides (n = 23 cromosomas) las cuales contienen un sólo set completo de cromosomas.

What are the two forms of stored chemical energy produced in the light reactions of photosynthesis?
A. ATP and NADPH
B. ATP and carbon dioxide
C. water and NADPH
Answer:
A. ATP and NADPH
Explanation:
The two forms of stored chemical energy is ATP (Adenosine Triphosphate) and NADPH (Nicotinamide Adenine Dinucleotide Phosphate).
Answer:
A. ATP and NADPH
Explanation:
The light reactions capture energy from sunlight, which they change to chemical energy that is stored in molecules of NADPH and ATP. The light reactions also release oxygen gas as a waste product.
how much of our body is made of muscle? What does this muscle do?
Answer:
about 30 percent of our body is muscle and we use only 10 percent of it
Explanation:
Answer: hello, the answer to you question is The muscular system is responsible for the movement of the human body. Attached to the bones of the skeletal system are about 700 named muscles that make up roughly half of a person's body weight. Each of these muscles is a discrete organ constructed of skeletal muscle tissue, blood vessels, tendons, and nerves.

Name the process in which a cell develops new sub-cellular structures to let it perform a specific function:
Answer:
Explanation:
In the process of differentiation the stem cells develop different sub-cellular structures to turn into the different types of cells - specialisation. The specialised cells can now carry out their important specific functions - essential for the efficient and healthy viability of any organism.
Cell differentiation is the process in which a cell develops new sub-cellular structures.
What is cell differentiation?It is a biological process in which cells in an entity acquire specialized roles and switch from one cell type to another.During human development, a fertilized egg differentiates into other specialized cells found in the body, such as muscle, neurons, etc. Stem cells are undifferentiated cells. These stem cells can be found in both embryos and adults.What is the purpose of cell differentiation?A single cell gives rise to all cells in multicellular organisms. Cell differentiation is how cells acquire their specific phenotype and functionality at maturity. Cell differentiation results in various cell types that perform essential functions.Why is cell differentiation significant?Occurs when a single cell develops into various tissues and organs.It aids in forming an organism from a single cell zygote.Thus, we can conclude that cell differentiation leads to a cell developing a new sub-cellular structure.

A man inherits dominant allele for the trait from father and recessive allele from mother. what trait will this man expressed which alleles will his sperm cell contain??
Answer:
Explanation:
The dominant trait, since he has a dominant and a recessive allele.
Sperm cells are haploid, meaning contains only one of the two alleles available, in a random fashion. Therefore on the average, half of his gametes (sperm cells) will have the dominant allele, and the other half will have the recessive allele.
Small, prolific mussels called zebra mussels were first introduced into the Great Lakes by a foreign cargo ship. They became a serious problem because they attached themselves to smooth, hard surfaces, and often clogged water intake pipes. Congress determined that zebra mussels posed a great threat to the economic welfare of the Great Lakes region and passed a statute requiring all Great Lakes water intakes to be coated with a special chemical compound that repels zebra mussels. Studies by biologists at a major state university showed that while the special chemical compound that the federal government has required was effective, it also was toxic to other aquatic life. The biologists recommended that Great Lakes intake pipes be coated with a less toxic and less expensive copper-based paint. On the basis of those studies and the recommendation, three Great Lakes states adopted laws permitting municipal water districts to coat their intake pipes with copper paint.
Can municipalities using copper-based paint on their intake pipes successfully be prosecuted for violating the federal law?
A. No, because the Tenth Amendment prevents Congress from interfering with integral government functions.
B. No, because the municipalities are taking effective steps to combat zebra mussels in compliance with the spirit and purpose of the federal law.
C. Yes, because Congress is in a better position to regulate the entire Great Lakes region than the individual states.
D. Yes, because Congress may adopt laws regulating navigable waters.
Answer: Yes, because Congress may adopt laws regulating navigable waters.
Explanation:
It should be noted that municipalities using copper-based paint on their intake pipes can successfully be prosecuted for violating the federal law because Congress may adopt laws regulating navigable waters.
Under the Supremacy Clause, when the action of either the state government or the local government conflicts with the federal laws which are deemed valid, then such cities can be prosecuted.
Human skin cells are specialized to do what
Answer:
The primary function of these cells is to create the barrier between you and the rest of the world. Keratinocytes produce the protein called keratin, and by the time the cells have been pushed up from the basement membrane, they are mostly sacks filled with keratin.

1) ATP levels would decrease
2) O2 levels would decrease
3) glucose levels would increase
4) CO2 levels would decrease
The container in which the snails are found will experience a decrease in oxygen level.(Option 2)
What are animals?Animals require to take in oxygen in order to breakdown complex food materials during the process of metabolism. Unlike plants that take in carbon dioxide, animals take in oxygen.
