-Natural selection leads to evolution.
-Evolution leads to natural selection.
-Natural selection is the same as evolution.
-Evolution and natural selection are not related.
Answer:
Natural selection leads to evolution.
Explanation:
Natural selection is a process where organism that are better adapted to an environment will survive and reproduce. This means that the advantageous alleles of this variants organism are passed on to offspring. Over many generations, the process of natural selection leads to evolution occurring.Answer: A. Natural selection leads to Evolution

Having dimples is a dominant trait. Having no dimples is recessive. A father has the genotype Dd and a mother has the genotype dd. If they have a child, what is the probability of their child having dimples?
The probability of the child of a couple with heterozygous father and homozygous recessive mother is 50%.
What are the recessive traits?Recessive traits and alleles refers to the relationship which is between an observed trait and the two inherited versions of a gene which are related to that particular trait. Individuals which inherit two versions of each gene are known as alleles, from each parent.
In the case of a recessive trait, alleles of the trait-causing gene are the same, and both alleles must be present in an organism to express the trait. A recessive allele does not produce a trait when only single copy is present. This contrasts to a dominant trait, which requires that only one of the two alleles be present to express the same trait.
The cross between a father with genotype Dd and mother with genotype dd will produce the child with dimples (recessive trait) and the probability will be 50%.

Explique em que medida os medicamentos diuréticos podem ajudar a diminuir a tensão arterial num paciente com uma dieta com ingestão de quantidades elevadas de sal.
Answer:
As drogas diuréticas ajudam os rins a aumentar a quantidade de sal e urina removida na urina. Isso é pertinente porque o excesso de sal no corpo pode levar ao aumento da pressão nos vasos sanguíneos. O excesso de líquido não necessário ao organismo é assim removido. Esses medicamentos tornam-se eficazes dentro de 2 horas após a ingestão. Um exemplo típico é a clortalidona.

If you lined up TMV ( tobacco mosaic virus) particles end to end, how many would fit along the length of the same paperclip? the paperclip is a length of 3.0 cm.
Answer:
100,000 TMV
Explanation:
Length of one TMV is 300nm. Length of paper clip is 3.0cm. First step is to convert either value to match the units of other.
So 3.0cm to nm is 3.0 * 10^7 = 30,000,000nm
SO now it becomes simple because we just divide the total length by length of TMV to find number of particles that can fit:
30,000,000/300 = 100,000 TMV

Which statement is true about the CO2 cycle? Reservoirs add more carbon dioxide to the environment than they remove. Carbon dioxide travels through the environment in a single direction. Carbon dioxide is constantly moving throughout the environment. When carbon dioxide enters a reservoir, it no longer cycles.
Answer:
Carbon dioxide is constantly moving throughout the environment.
Explanation:
The True statement about CO₂ cycle is ; Carbon dioxide is constantly moving throughout the environment ( C )
The CO₂ cycle is the process involving the addition and removal of carbon dioxide from the atmosphere and it involves several process like cellular respiration, photosynthesis and Burning of fossil fuels.
This cycle is a continuous process because carbon continues to move in and out of the atmosphere as long as respiration, photosynthesis and burning of fossil fuels remains a continuous process.
Hence we can conclude that The True statement about CO₂ cycle is ; Carbon dioxide is constantly moving throughout the environment.

How might disease be responsible for the rise in buffalo population that our investigation is centered on
Answer:
Suppose that the buffalo has a natural predator A.
Now, if there is new disease introduced, that particularlly atacks the natural predator A of the buffalo, we may be in a situtation where the percentage of the buffalo population that was predated by A is decreased (as we have a smaller number of predators A that are active). This means that we have more live buffalos, and as most biological organism, the growth of population is exponential. So having more buffalos today, means that in some months we will have plenty more of them, and this is why a disease can conclude in a rise in the population of some species.

Describe the relationship between temperature, rainfall, and the type of forest
Answer: The more rainfall, the bigger the tree, so that creates a rainfall
Explanation:
1. Trees influenced the temperature by soaking heat and having “refrigeration”, thus cooling local climates.
2. Soils also soaked more moisture than non-forest soils, more water for catchments and allowing trees to produce this moisture in the atmosphere.
How do temperature and rainfall affect the distribution of biomes?Biomes are determined largely by temperature and rainfall, biomes at higher latitudes ) are cooler and drier.
Nearer to the equator, biomes are generally warmer and wetter, as warmer air holds more moisture than colder air.
Thus, temperature, rainfall, and the type of forest are interconnected.

Explanation:
A change in body temperature will have which of the following effects on enzymes in the body?
O A change in the ability of some enzymes to bind with their coenzymes
A change in the ability of some enzymes to bind with their substrate
A reduction in the concentration of some enzymes in the body
An increase in the concentration of some enzymes in the body
Answer:
A reduction in the concentration of some enzymes in the body
Explanation:
As temperature is increased the enzymes and substrate gain kinetic energy (move more quickly). This increases the frequency of collisions and the formation of enzyme-substrate complexes. Therefore as the temperature is increased the enzyme activity and the rate of reaction increases.
Increases in temperature increase molecular activity, and can result in a higher rate of collisions between enzymes and substrates. If the temperature rises too high, however, the enzymes could become denatured, and the positive effects of the temperature increase could be nullified.

A sequence of three nitrogenous bases in a messenger-RNA molecule is known as a codon. Therefore, option A is correct.
What is a codon?The set of instructions utilized by living cells to convert data from genetic material contained in proteins is known as the genetic code. tRNA reads a triplet of RNA nucleotides. A codon is made up of three nucleotides. One amino acid corresponds to one codon.
There are 64 distinct codons, of which 3 serve as stop signals and 61 identify amino acids.
The genetic code contains the STOP codons UAG, UAA, and UGA. During translation, these codons indicate the polypeptide chain's conclusion. Because they do not encode an amino acid, these codons are often known as nonsense or termination codons. Therefore, option A is correct.
