No, some organisms have similar (analogous) structures but are not closely related . A more accurate way of finding evolutionary connections would be to compare the DNA of different organisms.
What is evolution?The gradual change of an organism over a period of time is called evolution.
Evolution is the population phenomenon. The sudden change in an individual is called a mutation.
These are the thing that leads to the evolution:-

which of these is a form of liquid precipitation
Explanation:
Rain and drizzle are the form of liquid precipitation.Can someone help MMEE!
Answer:
D
Explanation:
This may seem difficult to answer at first, cuz A and even B sounds plausible, but the relative direction of where she's drawing the picture is not known. And we know that the sun does not rise and set in the same place everyday. So the best answer would be D
23. Each trait has two alleles. How many alleles would have to be a dominant allele for the offspring to express a dominant trait
Answer:
One (1) of the alleles
Explanation:
According to Gregor Mendel in his series of experiments, he discovered that two forms of a gene called ALLELE contributed to the formation of a trait. However, in his law of dominance, Mendel stated that one allele called the DOMINANT ALLELE has the ability to mask the phenotypic expression of the other allele called RECESSIVE ALLELE when present.
This means that, in a combination of both alleles in a gene (heterozygous), only one allele coding for a phenotypic characteristics will be expressed. This phenotype is called the DOMINANT TRAIT.
For example, if tall allele (T) is dominant over the short allele (t), the tall trait will be expressed when the genotype is "Tt" meaning that only one of the alleles would have to be a dominant allele for the offspring to express a dominant trait.
Bats hunt using echolocation, in which they send and receive high frequency sounds to locate prey. When bats hear the sounds of others, they typically begin hunting in the same area. As the number of bats hunting in the area increases, individuals become more successful at locating and capturing prey.
Some populations of bats live in areas with high levels of noise pollution, such as near heavily trafficked bridges. How might the hunting behavior of bats be affected by such an environment?
A.
Bats would be better able to use echolocation, which would improve their ability to find prey.
B.
Bats would be unable to use echolocation, which would prevent them from finding any prey.
C.
Bats would be more likely to hunt in groups, so an individual's success in catching prey would increase.
D.
Bats would be less likely to hunt in groups, so an individual's success in catching prey would decrease.

Two short haired guinea pigs are mated several times. Out of 100
offspring, 25 of them have long hair. What are the probable
genotypes of the parents?
Answer:
Both heterozygous, with the trait for short hair being dom over the long hair
Explanation:
25% would be homzygous dominant, 25% homzygous recessive and 50% heterozygous

What would happen if the temperature was increased past 30°C?
Answer: we could frezze to death
Explanation: we would be to cold
When plants carry out photosynthesis the
chemical called _____ traps light energy
The
energy
is used to combine raw materials
to make______
The process mainly happens
in the
______ of leaf
>
The process mainly happens in the stomata of the leaf
Answer:
chemical : Chlorophyll
sunlight
the process of photosynthesis takes place in the mesophyll or stomata of the leaves
Explanation:
A few characteristics of a type of reproduction are shown below:
1. Involves two organisms
2. Gametes are not produced
3. Cell divides only by mitosis
4. Offspring show genetic variation
5. Involves one parent only
Which of the above are characteristics of asexual reproduction? (4 points)
1, 2, and 3
1, 3, and 4
2, 3, and 5
2, 4, and 5
Answer:
C. 2, 3 and 5 would be the answer
Answer:
2, 3, and 5 because sexual reproduce needs two parents, variation, and to produce gametes, asexual reproduction is the opposite

Explanation:
Where does fertilization take place in the female?
Answer:
Fallopian tube
Explanation: A pregnancy starts with fertilization, when a woman's egg joins with a man's sperm. Fertilization usually takes place in a fallopian tube that links an ovary to the uterus. If the fertilized egg successfully travels down the fallopian tube and implants in the uterus, an embryo starts growing.
How do human activities lead to primary succession?
Answer:
This succession is influenced by environmental factors such as soil type, water regimes, vegetation history, climate, and invasive species. Humans affect all of these factors. The human dimension introduces the greatest amount of unknown variability. Forest lands are under increasing development pressure.
What’s is the punnet square?
Answer:
The Punnett square is a tabular summary of possible combinations of maternal alleles with paternal alleles. These tables can be used to examine the genotypical outcome probabilities of the offspring of a single trait (allele), or when crossing

Logging entails cutting down trees and selling the timber. Identify the possible effects logging could have on various parts of nature.
During a field trip, an instructor gently touched a moth resting on a tree trunk. The moth raised its forewings to reveal brightly colored eyespots on its hind wings. The instructor asked why the moth lifted its wings. One student answere that sensory receptors had fired and triggered a neuronal reflex culminating in the contraction of certain muscles that ralsed the wings. A second student responded that the behavior frightens predators and that this allows the moth to escape. Which statement best describes these explanations?
A. The first explanation is biological, whereas the second is philosophical.
B. Both explanations refer to proximate causation.
C. Both explanations refer to ultimate causation
D. The first explanation refers to proximate causation, whereas the second refers to ultimate causation
E. The first explanation refers to ultimate causation, whereas the second refers to proximate causation.
Answer:
D
Explanation:
In protein synthesis, the role of the ribosome is to: A. Translate mRNA into tRNA B. read the mRNA code C. Pick up and carry amino acids D. Translate tRNA into amino acids PLEASE HELP!
Answer:
B. read the mRNA code
Explanation:
Ribosomes are cellular organelles present in both eukaryotic and prokaryotic cells. The ribosome is the site of protein synthesis in a living cell i.e. it is where the translation of mRNA into protein (amino acids) occurs.
The mRNA molecule is read in the ribosome with the aid of another type of RNA molecule called tRNA (transfer RNA). The tRNA in the ribosome reads the mRNA codon using its anticodon and carries the corresponding amino acid to the growing polypeptide chain. Therefore, the ribosomes play the role of reading mRNA code during protein synthesis.
After the milk and bacteria ferment, what are the two parts that we separate?
Answer:
Latic acid and rennet cause the milk to curdle,which SEPARATES the curds.
Why is phenomenon crossing over important?
DNA polymerase only travels in the__________to________direction.
Answer:One Direction
DNA Polymerase Only Moves in One Direction
Explanation:
After a primer is synthesized on a strand of DNA and the DNA strands unwind, synthesis and elongation can proceed in only one direction. As previously mentioned, DNA polymerase can only add to the 3' end, so the 5' end of the primer remains unaltered.
