What evidence did Darwin use to support his theory of evolution? Check all that apply.
in-depth studies of individual organisms
observations of fossils
finches on different islands had different types of beaks
young finches that acquired desirable traits as they aged
observations of different species with varying traits
Darwin used observations of fossils, variances in finches' beaks across different islands, and the diversity of traits among different species to validate his theory of evolution. These evidences solidified the basis for his concepts of natural selection and adaptive evolution.
Explanation:Charles Darwin used various forms of evidence to support his theory of evolution. This evidence played a critical role in the establishment of evolutionary biology as a valid scientific discipline. Key sources of evidence included observations of fossils, the noticeable difference in finches' beaks on different islands, and his vast observations of different species with varying traits.
His fossil observations allowed Darwin to perceive evolutionary change over long periods of time. The finches displayed how species could adapt in response to environmental factors, such as food availability, which impacted the form and function of their beaks. Moreover, his observations of diverse species exhibited the capacity of life forms to develop different characteristics in response to their circumstances, further grounding his argument for natural selection and adaptive evolution.

Determine which of the following characteristics are environmental, not inherited.
I. Weight
II. Blood group
III. Language spoken
IV. Eye color
Answer:
Environmental characteristics (not inherited): Weight and Language spoken.
Explanation:
Environmental characteristics are traits or features that are primarily influenced by external factors in an individual's environment rather than being inherited through genes. For example, weight can be influenced by factors such as diet, exercise, and lifestyle choices. Language spoken is another environmental characteristic as it is learned from the surrounding culture and the community a person grows up in. These characteristics can vary significantly among individuals based on their unique experiences and interactions with their environment.

The sun rotates
O
A. around Earth once per year.
O
B. at different speeds along its sphere.
O
C. every 31 days.
O
D. once per year.
Answer: B
Explanation: the sun is made of gas, which doesn't all spin together at the same speed like a solid rock would.
The sun rotates at different speeds along its sphere, a phenomenon known as differential rotation. The rotation period near the sun's equator is about 25 days and increases with latitude.
The correct answer to the question of how the sun rotates is B. at different speeds along its sphere. This phenomenon is known as differential rotation. Unlike a solid body like Earth, the Sun, being a gaseous body, does not rotate at a uniform speed. At its equator, the Sun's rotation period is about 25 days, but this rotation period increases with latitude — being around 28 days at latitude 40°, and up to 36 days near the poles. Galileo discovered this by observing sunspots and their movement across the Sun's disk, indicating that the Sun does indeed rotate on its axis.

Neritic zone = It is located on the continental shelf, the water is not very deep and many nutrients and sunlight are found. Open ocean zone = It is the ocean beyond the continental shelf where water is very deep and nutrients may be scarce.Molds, casts, coprolites, and petrified wood are all example of
Answer:
Molds, casts, coprolites, and petrified wood are all examples of fossils.
Explanation:
Molds are fossils formed by the authigenic preservation of an organism- it is covered gradually in mud or silt which hardens into rock leaving indents there after it has decayed. Similarly, casts are mineral deposit filled casts, which produce fossilized copies of the organism. Coprolites, fossilized fecal matter, are a type of trace fossil, which provides records the presence, diet and other habits of the organism in an area by its preserved excrement. Petrified wood,like molds and casts are mineralized, however the differs from molds as it has not undergone decay.
The correct answer is fossils.
Molds, casts, coprolites, and petrified wood are all examples of fossils. Fossils are the preserved remains or traces of animals, plants, and other organisms from the remote past. Here's how each of the given examples fits into the category of fossils:
- Molds are fossils that form when an organism's body decays completely, leaving a hollow space in the rock that is the exact size and shape of the organism.
- Casts are fossils that occur when the hollow space left by a mold is filled with minerals, creating a replica of the organism's body.
- Coprolites are fossilized feces that provide information about the diet and behavior of ancient organisms.
- Petrified wood is formed when the organic remains of a tree are replaced by minerals, turning the wood into stone. This process preserves the original structure of the wood in fine detail.
Each of these fossil types provides valuable information about the biology and ecology of past life on Earth.

Label the steps for protein synthesis in order, beginning with the first step
The steps for protein synthesis in order are:
1. Copy of one side of DNA strand is made (called mRNA, messenger RNA)
2. mRNA moves to cytoplasm, then ribosome.
3. mRNA goes through ribosome 3 bases at a time.
4. transfer RNA (tRNA) matches up with the open DNA bases.
5. tRNA releases the amino acid at the top, which joins the chain of amino acids being produced.
Answer:
Steps of protein synthesis:
1) DNA double helix unwinds into a single strand and exposes a sequence of nitrogenous bases, this is also known as the unzipping process.
2) Transcription: In this process, DNA transfer the genetic instruction to mRNA in the nucleus.
3) Translation: In this process mRNA couples the ribosomes & tRNA helps to bring amino acids to ribosomes. This process is known as Initiation.
4) Elongation: Anti-codons present on tRNA recognizes codons present on mRNA.
5) Termination: In this step when the stop signal on mRNA is reached, the process of protein synthesis is terminated.
