Answer:

i'm learning DIT

Explanation:

so this year we were learning excel, word, and PowerPoint. currently we are learning how to use word in the beginning it was excel because my teacher said it was the hardest and would take the longest then we learned PowerPoint and last we learned word

Answer:

scientist is attempting to build a cladogram that shows the evolutionary closeness of three organisms in relation to humans. After doing DNA analysis, they determine that the organisms share the following percentages of DNA:

Organism A and humans share 85% of their DNA.

Organism B and humans share 80% of their DNA.

Organism C and humans share 90% of their DNA.

Based on this information, which order should they go on the cladogram (from least related to most related)?

(1 point)

A, B, C, humans

C, B, A, humans

C, A, B, humans

B, A, C, humans

2.A cladogram shows the evolutionary relationship between humans, chimpanzees, and gorillas. The cladogram currently shows humans and chimpanzees with a more recent common ancestor compared to gorillas. Which piece of evidence, if true, would most likely weaken this hypothesis?(1 point)

Fossils of humans appear in deeper sedimentary rock layers compared to fossils of chimpanzees.

Amino acid analysis of the cytochrome c protein shows significant differences in the sequence of amino acids between humans and gorillas.

DNA sequence analysis of the hemoglobin alpha gene shows that humans and chimpanzees have a more similar sequence to each other than they do to the gorilla’s DNA sequence.

The cells of the eye in embryos of gorillas and humans follow a similar pattern of development while chimpanzee embryos are different.

3.The forelimbs of bats and humans have a very similar bone structure even though they appear very different on the outside. These structures are known as __________ because they result from species evolving __________.

Which of the following answer choices correctly completes the above statement?

(1 point)

homologies; similar adaptations in similar environments

analogies; from the same common ancestor

analogies; similar adaptations in similar environments

homologies; from the same common ancestor

4.All vertebrate embryos have a tail and gill slits at some point during embryonic development. What does this suggest about vertebrates?(1 point)

The embryos of these species require these structures to survive.

These species evolved in similar environments.

These species have the exact same DNA sequence.

These species share a common ancestor.

5.Fossil A is found closer to the surface compared to Fossil B. Which of the following conclusions can be made based on this statement?(1 point)

Fossil A is from an older species than Fossil B.

The species of Fossil A existed at the same time as the species of Fossil B.

The species of Fossil A evolved from the species of Fossil B.

Fossil B is most likely older than Fossil A.

6.Vertebrate embryos all follow a very similar developmental process. Which statement could explain this similarity?(1 point)

All vertebrates require the same nutrients during embryological development.

All vertebrates develop a backbone that protects the spinal cord.

All vertebrates inherit the same sequence of DNA from their parents.

All vertebrates live in similar environments which require the same adaptations.

7.Some mutations, or changes in the sequence of DNA, do not have any effect on the characteristics of the organism. Why is this?(1 point)

The immune system repairs the mutated sequence during development.

The protein built from this mutated sequence is deactivated by the cell.

The mutated sequence still codes for the same amino acid.

The cell recognizes mutations and ignores them when expressing the gene.

8.What is typically studied when analyzing not-yet-born (or unhatched) animals?(1 point)

embryological development

evolutionary theory

causal records

DNA sequencing

9.What can scientists analyze to get a better understanding of how plants and animals evolved from a common ancestor?(1 point)

petrified bones and imprints of plants

DNA molecules

vertebrate embryos

life cycles and behaviors

10.How can embryos help scientists understand evolution?(1 point)

Embryos contain the code for all life on Earth.

Embryos go through various stages that suggest the animal’s evolutionary process.

Embryos provide evidence for which life forms existed at the same time.

Embryos are frequently fossilized and illustrate change over time.

11.Astronomers have made great strides in sending probes out to other planets and moons in our solar system. If they were to find a living creature some place other than Earth, how could DNA analysis help them better understand the organism? Explain in 1–2 sentences.(2 points)

12.In 1973, biologist Theodosius Dobzhansky wrote an essay titled “Nothing in Biology Makes Sense Except in the Light of Evolution.” Why is evolution so important for understanding biology? Explain your answer in 1–2 sentences.(2 points)

13.You are a scientist tasked with writing a journal article on the evolution of alligators. In 3–5 sentences, describe the different forms of evidence you might use to analyze the evolution of alligators.(4 points

maw [93]

Complete Question:

1. Organisms don’t all reproduce the same way. However, by comparing the ____ of these organisms, many similarities between them are ____

2. of these organisms, many similarities between them are revealed. These similarities suggest that they’re ___ linked. This type of study is called developmental biology.

Group of answer choices.

A) Cells B) Embryos C) Mode of reproduction D) Evolutionarily. E). Revealed.

Answer:

embryo; revealed; evolutionarily.

Explanation:

Reproduction can be defined as a biological process which typically involves living organisms producing an offspring.

Basically, there are two (2) methods of reproduction and these are;

I. Asexual reproduction: it involves the cloning of a living organism to produce an offspring because there is only a single parent.

II. Sexual reproduction: it involves the combination of the genome (gamete) of a male and female living organism during fertilization.

It's a fact that all living organisms do not reproduce the same way.

However, by comparing the embryo of these organisms, many similarities between them are revealed. These similarities suggest that they’re evolutionarily linked.

Hence, we refer to this type of study as developmental biology
